Brief Statements Based on the Unit
The topic of this unit is about the human being’s 1ife in the future．This unit is made up of warming up，listening，speaking，pre-reading，reading，post-reading，language study and integrating skills．These tasks will be finished in five periods．
In the first period，we’ll do warming up，listening and speaking to improve the student’s listening and speaking abilities．At the same time．arouse the students’interest in the topic of this unit．
In the second period，we’ll finish the task 0f pre-reading,reading and post-reading．In post-reading，let the students give free rein to their imagination by discussing some questions．We’11 read a passage about 1ife in the future．It will tell us what the human being’s life will be like in the future．In the meanwhile we’ll learn some useful words and expressions．
The third period consists of two parts：Word study and Grammar-Noun Clauses．
Through word study we’ll revise some words and phrases，which are related to the topic of this unit．As to the grammar：Noun clauses,we can master them by doing more practical practice given in the textbook and workbook．
The main purpose of the fourth period is to train the students’reading and writing abilities by reading and writing a short pas-sage about 1ife in the future．
In the last period,we’ll deal with the grammer in this unit-Noun C1auses．
In a word,we can train the students’listening,speaking,reading and writing abilities by doing the exercises the textbook and the workbook provide．
Ⅱhing Goals
1．Talk about life in the future．
2．Practise making predictions．
3．Learn about Noun Clauses(2)．
4．Write a definition paragraph．
Ⅲ．Teaching Time：Five periods：
Ⅳ．Background Information
d in the Future
Scientists think that wonderful things may come true in the future．Future means a time that not yet come．It can be a short time from now or a long time from now．Some of the underwater wonders are almost ready to come true now．Others won’t come true,we think，until a long time from now．Some,of course．may never come true-but
who knows for sure?They may．What are some of the wonders that may come true in the future?
Let’s go back to dry land and take a future journey the other way--up instead of down．
Huge rocket liners take you into space to visit the Moon Camp．You walk around on the moon in s special moon suit．You visit an observatory where a giant telescope looks far into space--farther than anyone has ever been able to see from Earth．You go deep down into one of the moon mines．
After you have visited the moon,you visit the Mars Colony and the Venus Explo-ration Outpost．
Let’s go back to Earth．
In the far，far future，girls-and boys,too--may be playing with dolls that look like the people of the planets visited by our space-man．
To control or run all kinds of toys,boys and girls may learn to use special ccmputers--machines that answer questions and do arithmetic faster than you can think．
Bicycles and perhaps skates may be run by jet power,and a new thing to ride may be a small flying saucer．Imagine a race between them!
There may be telepathy helmets that send thought waves from your brain to that
of your friend miles away．You just think a thought and your friend knows it!You can have secrets with each other that nobody else can turn it on!
There will be other surprises in the future．How would you like to have a robot
playmate?
Having robot playmates may not be so much fun as it seems．But maybe a boy with a wrench and a screwdriver can fix the robot so that it won’t be too perfect!
What about the food of the future? Scientists think that much of it will be artificialmade in factories from such surprising things as coal．1imestone。air and water．
You don’t think that ice-cream or cake or candy or even bread and potatoes made out of these things will taste very good．You may be wrong．These artificial things will be blended so skillfully be food chemists that the food of the future probably wi11 be delicious．It probably will also be healthful be-cause life will be put into it．
Scientists of the future will almost certainly find other ways to make life last longer．They probably will find cures for most diseases．Hospitals will probably have“body banks”that can give you almost any new part you need to keep on living．People of the future may live to be a lot older than 100 years．
Are you wondering whether there’11 be television in the future? There’ll almost certainly be wonderful programs. Television screens probably wi11 be large and flat，hanging on the wall or going across the four walls of a room．People on the screen will look real as if they were right in the room with you．What about highways of the future? Well, a very small child probably will be able to drive a car．Nobody will need to steer．Electric signals will hold each car on the right road to get wherever the“Driver”wants to go．And it probably will be impossible for cars to smash together。Controllers that won’t even have to be touched will make all speeding cars miss each other or will put on the brakes．Driving in a car will be as safe as being at home．
But maybe the most wonderful surprise in the future will be weather control，Cities may have giant plastic domes over them to keep out snow，rain，or storms．
When you plan a picnic in a park。you won't have to worry about rain．It will rain only when the“ weatherman”thinks it is needed to freshen the air inside the city．All other days will be fair and warm．
The future should be a wonderful time in which to live．But the time you are living in now was also“ a wonderful future”to the people who lived 100 years ago．
2。Three Things That Will Change Your Life
Today our lives are changing faster than at any time in history．Here we report on three important changes that will have a big impact on our everyday lives in the future．
The cashless society Cash and bank-notes wi1l disappear almost completely．They will be replaced by smart cards--plastic cards with microchip processors“loaded”
with some money．When we pay for goods．the retailer w1l insert our smart card into a payment terminal and money w．1l be transferred from our card to the retailer's card．When all the money is used up，we will be able to“re-load”it by inserting it into a telephone，dialing our bank account and transferring money to the card from the account．1f we want to transfer money from our card to a bank ac-count．we will use the same method．Smart cards will be able to hold several different currencies at the same time．so if we go aboard．we will use our smart cards in the same way．
Interactive telephones Human telephone operators will be sharply replaced by talking computers．These computers will recognize speech．ask us what information we need，access the information from a database，and convert it to speech．If we want to book a flight or pay a bill by phone，we will interact with a talking computer to do SO．Of course，this won't happen until all the technology is
in place，but when it is we will soon get used to interacting with computers in this way．Human telephone operators will be used only for more complex operations
such as dealing with complaints or solving concrete problems．
Intelligent cars Traffic congestion in cities will be reduced because drivers will use electronic route maps to find the quickest route to their destination and avoid traffic jams．Congestion will also decrease when electronic systems start changing motorists for driving in cities．As soon as motorists have to pay to drive in cities，they will stop Using their cars and use public transport instead．
Speed control systems will be built into cars．These systems will automatically regulate the speed of the car to take account of traffic and weather conditions and prevent accidents．It will be many years before these changes bring results but when they do，there will be a titanic improvement in road safety．
The First Period
Teaching Aims：

n the students'1istening ability．
ove the students’ speaking ability by practising making predictions．
Teaching Important Points：
1. Train the studcnts'1istening ability．
2. Let the students give free rein to their1 imagination.
Teaching Difficult Points：
1．How do improve the students' listening ability．
2．How to finish the task of speaking.
Teaching Methods:
1．Listening-and-answering activity to help the students go through the listening material．
2．Individual，pair or group work to make every student work in class．
Teaching Aids：
1．some pictures
2．a tape recorder
3，a projector
4．the blackboard
Teaching Procedures：
Step I Greetings and Lead-in
T：Good morning／afternoon，everyone.
Ss：Good morning／afternoon，teacher.
T：Sit down，please．Now we're having a class in a bight and spacious class-room with modern equipment such as radios and computers．And we all live a happy life today．We can get whatever we want．Do you know how did people live in the past?
(One student stands up．)
S：When I was a child，my great-grandfather often told me the stories of him in the past. He often got hungry and didn’t have enough money to go to school and had no chance…I think people live a miserable life in the past.
T：Yeah．People lived a hard in the past．With the development of science and technology, people's life has changed a lot．Now we all live happily. What do you imagine life will be like in the future? Today we are going to study Unit 6 Life in the future. (Bb: Unit 6 Life in the future)It will tell us what life will be like in the future.
Step Ⅱ Warming up
T：Now let's first have a discussion about the future of one of the areas in our books．Discuss them in groups of four．After a while，I'1l ask one of you to re-
port the results．
T：Now please discuss some questions．(Show the picture and questions on the screen．)
How will people travel in the future?
Where will they go? Why?
(Give the students another two minutes to discuss．)
T：Who’d like to tell me how people will travel in the future and where they will
go and why?
(One Student puts up his hand．)
T：Oh，Li Jun，you have a try．
S：I think people will travel by using public transport．Electric cars will be
traveling through the streets day and night．Anybody will be able to stop one and take it．They can go wherever they want．
S：I think people will travel by car，which doesn't burn gas，but solar energy．In-
stead of wheels，the car needs a Cushion of air．Thus。it can float in the air．You
can go wherever you want as long as you press a button on the computer in the
car．What's more，it won't cause any pollution．
(And then ask some Students to re-port．)
How wi1l people communicate in the future?
S: People will communicate with each other with computers, which are set in the watches.
Where will people work in the future?
What kind of jobs will they have?
S：People wil1 work at home．The only thing that people do is to control the robots by pressing the buttons on t11e computer and let them work for us．
How will people do business in the future?
What kind of money will they use?
S：By the year 2l00，shops will no longer exist．Computers will have replaced them，and people will order goods from home．Instead of paper money，they will use credit cards．
What languages will people speak in the future?
Will people still speak Chinese and Eng1ish?
S：Instead of any language，people Will use code to talk with each other．If they use a language to communicate，I think t11ey Will speak Chinese．Because our country will be the strongest one．
What will schools be like in the future?
What subjects will people study?
S：Schools will be set up on the Internet．Students can stay at home and use computers to study．We can also down-load some information．We'll study social sciences，natural sciences and so on．Schooling wi11 be much more interesting and effective．
(After discussing all the questions，the teacher says the following．)
T：In spite of all these changes，man in the future will still have a lot in common with us．They wi1l have thoughts and emotions similar to ours．Anyhow，they will be human beings．
Step Ⅲ Listening
T：Now open your books at Page 42．Let's do some Listening．First Part 1．You're going to listen to a letter about Mekanika's life．Listen carefully and pay
attention to the year when she is living，the place where she 1ives,the things that happened to the people on the earth and the reason why she is writing you this letter．Write down what you hear．At last I'll check the answers with you．Is that clear?
Ss：Yes．
T：OK．Let's begin．
(Teacher plays the tape for the first time．Then plays for the second time，during which time teacher may pause for the students to write down the in-formation
．Finally teacher checks the answers in Part l with the whole class．)
T：Next listen to Part 2 and do the two exercises in them．
(Teacher lets the students go through the Exx in Part 2 and then plays the tape for the students．At last check the answers．)
Step Ⅳ Speaking
T：NOW look at the picture in Speaking Part．There are two girls in the picture．One girl is working on the computer．The other is making a phone call．Can you find anything different between them?
Ss：No．They are the same．Maybe they are twins．
T：No，they aren't twins．One of them is cloned．With the development of technology，scientists will be able to clone persons as well as animals．Suppose the year is 2089 and scientists have discovered how to make“doubles”，ex-act copies of a person that can do everything the original can do．Now work in groups of four to discuss the question whether the new techno1ogy should be used．First give your opinion and tell the reason．Write it in your textbooks．After that make up a short dialogue,
using the information in your books and the useful expressions on the blackboard.
(Bb：It would be wonderful if…
It would be bad for…if…
It’s possible/impossible to predict…
No one can predict what／when…
Just imagine if…
We can only guess…)
(Teacher gives the students four minutes to prepare in groups of four and then asks some groups to read their dialogues before the class．)
Sample dialogue：
SA：With the development of science and techno1ogy，the double would be made in the future．I think it would be a good idea to have a double. Because we could use the double to do the things we don't enjoy，for example, we could let the double finish our homework．
SC：I agree with you．I would 1ike to have a double, too，because I don't have time to do all the things I'd like to do．For example，if I didn't have time to watch an exciting football game, I would let the double watch it.
SB：I don't agree with you．I think having a double might be dangerous because you don't know what the double might do．For example，the double might steal what they what they want or kill the person they hate.
SD：Yes，they might do something wrong. What's more，having doubles would make people confused，because no one would know who the double really was or how to treat it．For example, the double wouldn’t have any parents and no one would see to them.
SC：But having a double would be wonderful，because you could let the double do whatever you want them to do．
SA：Having a double would also be good because the double could attend an important meeting instead of you if you were ill．
SD：But I think it would be bad for society if people had doubles because they would make trouble for our society.
Step V Summary and Homework
T：Today we've done some listening and speaking and known how to make pre- dictions．Besides，we've also learnt some useful expressions on the black- board．After class．write down the dialogue you made in your exercise books and preview the reading passage on Page 43．

S：Let me try．In the future, we will travel by car，taxi，bus or train that won't pollute the air any more．We’ll buy things on the Internet instead of in the shop．
And we’ll be able to enjoy a longer and healthier life…
Step Ⅱ Word Study
T：Very good．In the text．we also learnt some important words and expressions．Now let’s have a dictation．Take out a piece of paper and write them down on it．
(Teacher dictates the words and expressions learnt in the last two periods.
Including forcast，trend．Urban consumer，tiny，customer, cash，regularly．effort，and physician．After that，let the students hand them in．)
T：OK．Now look at Language Study on Page 45．First look at Ex．I in Word study．Read the sentences and find a word from what we dicatated just now to complete each. You are given five minutes to do it．Read first and then complete the sentences according to the meaning of them．Is that clear?
Ss：Yes．
T：OK．First do it by yourselves．Then discuss them in pairs．After a while，I’ll ask some of you to say you’re answers and give the Chinese meaning of each sentence．
(After a while，teacher checks their answers and corrects the mistake if any．Teacher can give some explanations．)

T：Well done．Now look at Ex2．Choose the correct phrase to fill in each blank．First look at the phrases in the box．Let’s revise the meanings of them together．(Students say the Chinese meanings of the phrases together．) Now you're given three minutes to finish it．
(After a while，teacher checks their answers.)
Suggested answers：
In general, in store, keep in touch with, lead to, paying no attention to
T：Now read this passage again and try to continue the story．Write an ending to the story．After a while，I'll ask some of you to read out your story．
(After a while，ask some students to read out their own ending to the story．)
Step Ⅲ Grammar
T：Thank you for your stories．Now please look at the sentences on the blackboard．
(While the students are preparing their stories，the teacher writes the following sentences on the black-board and underlines the clauses with coloured chalk．)
(Bb：1．Who bought the book is un-known?
2．They know that the habit may kill them．
3．All I can say is that he has always been good to me．)
T：Who can tell me the function of the clause in each sentence? Any volunteers? OK．Wang Li，please．
S：In the first sentence，“who-clause” is used as the Subject．“That-clause” in the second sentence is an object clause while in the last sentence “that-clause” is a predicative clause．
T：Is what she said right?
Ss：Yes．
T：Very good．In the Object Clause“that”is optional and can be omitted．But in the Predicative and Subject Clauses，“that”is necessary and can not be omitted．You must remember that．Are you clear?
Ss：Yes．
T：OK．Look at the sentences on the screen and tell which part the Noun Clause act as．
(Show the following on the screen．)
1．What life will be like in the future is difficult ot predict．
2．They are careful about what they eat and exercise regularly．
3．The schools of the future will proba-bly be quite different from what they are today．
4．We can not be sure whether our dreams will come true，but we can at least be hopeful that…
5．If we learn to accept change and appreciate what is new and different, we will be well-prepared for whatever the future may have in store．
(Teacher asks the students to do it one by one．)
S1：“What life will be like in the future” is used as the subject．
S2：“What they eat and exercise regularly” is the object of preposition“about”．
S3：“What they are today” is the object of preposition “from”．
S4：“Whether our dreams will come true” is used as the predicative．
S5：“What is new and different” is used as the object of verb “appreciate” and
“whatever the future may have in store” serves as the object of preposition “for”
Step Ⅳ Practice
T：OK．Look at Part 2 on Page 46．Use the expressions in the right box to change your questions about the future in the left box into Noun Clauses．You may do like this．
e.g．How we should use modern technology is a big issue．But you should pay attention to the word order in the Notm Clause．Normal word order is used in it. Do you understand?
Ss：Yes．
(Give the students three minutes to practise and then ask some of the students to read out their sentences．
One student, one sentence．)
Suggested answers：
1.I can’t imagine what the advantages of e-schools are．
2．Scientists have(not)found answers to the question why there is no life on the moon.
3．The problem is how we should use modern technology．
4．We cannot be sure when we’ll be able to travel in space．
5．They are worried about whether robots will be smarter than people．
6．We cannot be sure whether the future will be better．
T：Now let’s do the exercise in Part 3．The main purpose of this exercise is to
help you understand the differences between a Noun Clause and an Attributive C1ause．Who’d like to tell me the differences between them?
S：I’d Iike to try．A Noun Clause is used as a subject，object，predicative or op-
positive in the main clause．An Attributive Clause serves as an attribute to
some noun or pronoun in the main clause，and it is often placed after this noun or pronoun．The Attributive Clause is introduced by the relative pronouns and the relative adverbs．
T：Very good．Sit down please．Now please read the sentences in Part 3 first．Then identify the type of clause in the sentences．If it is a Noun C1ause，write“NC”；if it is an Attributive C1ause，write“AC”．Are you clear?
Ss：Yes．
T：Now you are given three minutes to prepare it．
(Three minutes 1ater，ask five students to say their answers one by one．)
Suggested answers!
1．NC 2．NC 3．AC 4．AC 5．NC
T：Well done．Now look at Part 4．Re-write the sentences so that they be-come the type of noun clauses in brackets．If you have any problem，you can look at the example．
(Teacher gives them four minutes to finish it．After that, ask the students to read out their sentences．)
Suggested answers：

T：In this unit，we’ve also read a passage about life in the future．Now please
think out some words you can use to describe life in the future．
(After a while，ask some students to say out the words．)
Step Ⅲ Reading and Writing
T：OK．As we know，people’s life has
been changing．It’s getting better and better．What do you think life in the 3lst
century will be like?will it be the same as that today?
Ss：No．We think life in the 3lst century will be very different from that in this century．We’ll live more easily than today．We’ll have a machine do what we want them to．The only thing we need to do is to press the buttons on the computer．
T：OK．Thank you．Today we’re going to read a letter about the way people will
live more than one thousand years lat-er and we can know what the life in the 3lst century will be like．First let me explain some phrases to you：keep sb．Company,a bit and clear up．
(Show the following on the screen．)
sb．company：remain with sb．so that he is not alone．
stayed at home to keep his wife company．
I’ll stay here and keep you company．
2．a bit：rather
e.g．He is feeling a bit tired．
The book costs a bit much．
3．clear up：put in order／make sth．Tidy
e.g．Clear up your desk before you leave the classroom．
Would you please clear up the cup-board?
(Bb：keep sb．Company,a bit，clear up)
T：Now open your books at Page 47．Look at Reading and Writing．Here is a letter from Mekanika．Now you’re given four minutes to read it．Then answer some questions under the letter．
(The students begin to read．After a while．teacher checks their compre-hension．)
T：Who’d like to tell me what you would use an e-friend for，if you had one?
(One students stands up．)
S：Let me try．If I had an e-friend．I would let him help me with what I couldn't do，keep me company,talk with me and help me with my homework．
(Another student begins to give the answer．)
S：I think I would have the e-friend help me take notes when I was listening to a lecture and play chess with me．Fur-thermor，I would let my e-friend help me if I was in trouble．
T：Thank you．Now the second question：Why is it sometimes difficult for Mek-anika to know what is real and what is an image?Any volunteer?
S：Because the world and people are imi-tated so well that we can see them，hear them，touch them，talk to them and feel them．They are just like the real world and real people．
T：OK．The last question：How is our 1ife different from the way people lived one thousand years ago?
S：Now life is much easier and more con-venient than in the past．We can keep in touch with each other by cellphone or by computer instead of by writing letters．
S：We can travel by car instead of on foot．We can buy things on the Inter-net．We can also get the latest infor-mation by surfing the Internet．
…
Step Ⅳ Listening and Reading Aloud
T：Now let’s listen to the tape．When I play it for the first time，just listen carefully．When I play it for the second time，please listen and repeat．Then read the passage aloud．Pay attention to your intonation．Are you clear?
S：Yes．
(Play the tape for the students to lis-ten．Then when the students read the passage．the teacher goes among them and corrects their mistakes in pronun-ciation，intonation and stress．)
Step V Writing
T：We have known what the life will be in the year 3044．Imagine that you have come back from a trip to the future．You visited the year 4367 and you saw a wonderful invention called a Mogray．Now work with your partner and decide what a Mogray is，what it looks like and what it is used for．
(Teacher asks the students to discuss the questions．And then collect their
answers．After that，the teacher says the following．)
T：Now you know what it is like．Please write a paragraph about what a Mogray is．Before writing，you have to complete the outline on the screen．
(Show the following on the screen．)
What can a Mogray
Be used for? What does a Mogray
look like?
How does it work?
(Teacher asks the students to write the outline in their exercise books．Students may have various answers．)
T：OK．You have finished your outline．Please use it to write your paragraph．
(Teacher may let the students hand them in after class,if time is limited．)
One possible version：
Life in the year 4367 is quite differ-ent from life in the 21st century．We will
still do many things we do today，but we do them differently．For example，we can
use a Mogary to help us．A Mogary is an intelligent robot，which looks exactly like a human being．It can be used in many fields．such as at home，in the factory or in nature．
The Mogray can be easily and con-veniently used at home．If you want to travel，you can turn it into all kinds of transport that you like，such as a plane，a car or a train，which use the solar energy without pollution．When it is too cold or
too hot，the head of the Mogray can be used as an air-conditioner,which can keep a proper temperature．There are all kinds of recipes in its head．It can cook all kinds of healthy and delicious food for yoi if you press the buttons on it．When you are bored，it can read some books for you，which are stored in its brain．It can also play chess with you or communicate with you．It has thoughts similar to yours,Your life will be rich and colorful with a Mogray companying you．
It can be used in many fields．In a word，the earth will become even more beautiful with the help of it．
Step Ⅵ Summary and Homework
T：Today，we’ve learned a passage about the life in the year 3044．At the same time，we wrote a passage about the life in the year 4367．What’s more，we’ve revised the Noun Clause and the useful expressions in this unit．such as in general,keep in touch with，in store…(Write them on the blackboard．After class，you should master them further by revising what we’ve learnt in this unit．Don’t forget to prepare for the next unit．That’s all for today．Class is over．)

(Teacher shows the exercise on the screen．)

S2：The second answer is B．
S3：The third answer is D．
S4：The last answer is D．
T：Well done!Sit down，please．Who can tell me what clauses they are?
S5：…
Suggested answers：
Subject Clause
2．the Predicative C1ause
3．the Appositive Clause
4．the Obiect Clause
Step Ⅲ Explanation and Summary
T：As we all know，the Noun Clauses can be classified into the Subject C1ause,the Predicative Clause，the Object Clause and the Appositive Clause ac-cording to the function of each clause in the main clause．
(Bb：the Subject Clause．the Predica-tive Clause，the Object Clause and the Appositive Clause)
T：Now look at the sentences on the screen．
I．the Subject Clause
1．Whether he has enough time to finish the work is still a question．
2．It is still a question whether he has enough time to finish the work.
3. Who did that is unknown to all.
Ⅱ Predicative Clause
1. The question is who can do the experlment.
2．He looked as if he was going to cry．
3．The reason for his lateness was that he got up late．
4．That was because he got up late．
Ⅲ．the Object Clause
1．I didn’t know that Pierce Brosnan is from Ireland.
2．I find it hard that I learn English well．
Ⅳ．the Appositive Clause
1．Some senior officials eat chicken in public in order to remove the Chi-nese citizen’s fear that it is not safe to eat chicken．
2．Word has come from his sister that she will arrive on Friday．
T：Attention，please．1．In order to keep the sentence balanced．We often use“it”as the formal subject,which re-places the real subject．For example,the No．2 sentence in the column of the Subject．2．“As if”“as though”and“be-cause”can also be used to introduce the Predicative Clause．For example,the No．2 and the No．4 sentences in the column of the Predicative Clause．3．In the sentence if the verb is“make／find／think／believe…”,we can“it”as the formal object,which replaces the real object．We put the real object behind the Object complement．That is to say，
Sub．+find／make／think／believe…+it+Object Complement+that clause．For example，I thought it strange that he failed to call me．Now we have known about the usages and the func-tions of the Noun Clauses．But we must pay attention to the conneetives introducing the Noun Clauses．Now please look at the diagram on the screen．You’d better remember them．
(Teacher shows the diagram on the screen．)
T：Attention,please.
1．In the Noun Clauses，we must use the normal word order-Connective
+Subject+Verb．That is to say,there is no inversion．
e.g．Whether he left is unknown．
That’s why he fell i11．
Can you make sure where Alice has left the gold ring?
The fact that he hadn’t said any-thing surprised everyone．
(Teacher writes the four sentences on the blackboard．)
2．Don’t use double connectives in the Noun Clauses．
3．The subordinate conjunction“wheth-er”can introduce all the Noun Clau-ses，while the subordinate conjunc-tion“if”can only introduce an Ob-ject Clause used as the object of a verb．For example，we can’t say“It all depends on if they will support us”．We should say“It all depends on whether they will support us”．
4．The subordinate conjunction“that”has no meaning and doesn’t act as any omponent in the Noun Clau-ses．When“that”is introducing a Noun Clause as the object of a verb(believe，consider，hear，know，say，understand etc)，it can be omitted．
5．The conjunctive pronoun“what”means“the thing that／all that”in the Noun Clauses．“what”intro-duces a Noun Clause．At the same time it can be used as the subject，the object or the predicative in the Noun must pay atten-tion to the differences between“that”and“what”．Now let’s look at these sentences on the screen．
That she was closed made us very happy．
What he did quite surprises us．
This is what interests me most．
The reason was that he had never seen her before．
Stcp Ⅳ Practice and Consolidation
T：Now you have known something about the Noun Clauses．Let’s do some exer-cises so that we can use them correctly and freely．Please look at the screen．
