Step I Warming up

Show the pictures of some great scientific achievements that have changed the world on the PowerPoint. Divide students into groups and ask them to discuss which one is the most important and what these achievements have in common. (The exercises in warming up on Page 1).Students may have different opinions. The most important thing is to encourage them to think and express their opinions.

T: Please look at these great achievements and work in groups and discuss the following questions. You may have different answers. But you will have to tell us your reasons. (Show the following questions on the PowerPoint.)

1. Among the great scientific achievements that have changed the world, which one do you think is the most important? Why?

2. What are some other scientific achievements that you think are important?

3. Do these achievements have anything in common? If so, what?

Five minutes later ask some students to speak out their opinion.

T: Ok. Please stop here. I’d like to listen to your opinions.

S1: I think electricity is the most important. The modern world cannot work without electricity. Electricity has changed our way of life. This summer in some areas there wasn’t enough electric power, so some factories had to close and people had lot of problems in life.

S2: In my opinion the most important is Radio and television. Radio and television have changed the way we look at the world.

S3: That’s true. But I still think the most important is solar energy. Because by using solar energy, we can save other energy resources. And what’s more we can protect our environment…

T: Good! Do these achievements have anything in common?

Ss: These great achievements have changed the world.

S8: And all these great achievements were made by westerners/ foreigners.

T: That’s true. My dear students please think thousands of years ago our ancestors made 4 great inventions that changed the world. We are proud of them. But among the recent 75 greatest achievements, none was achieved by us Chinese .So I hope you study hard and make great scientific achievements. I will be very proud of you. Every Chinese will be proud of you.

Step II Listening

T: The listening material contains two parts. You are going to hear some words said by some famous people at the time when they achieved success. Can you follow me?

Ss: Yes.

T: Well, now look at the chart in Exercise 1 at the top of Page 2 quickly. Then I’ll play the first part of the tape for you to complete it. After that, I’ll check your answers.

(After checking the answers to Exercise 1,teacher goes on to deal with Exercise 2)

T: Well done. Now, listen to Part 2 and complete the sentences in Exercise 2.If necessary, I’ll play it twice for you to finish or check your answers. OK?

Ss: OK.

T: I’ll play it. Listen carefully!

(At last, teacher deals with Exercise 3.)

T:OK. So much for the tape. Now imagine you were the first person on Mars, or the first cloned human being or the first person to travel in time, what would you say? Any volunteer?

S1:If I were the first person on Mars, I would say “I’m here from the earth.”…

S2:…

T: Wonderful. If you want to do research about something, besides hard work, what else do you need?

Ss: Modern equipment and money, especially money. You get enough money, and then you get the equipment you need. Funds are essential for doing research.

T: You are right. Now, please look at the Speaking part.

Step III Speaking

T: Here are four scientists who want to get money to complete their project. Each scientist will have to introduce his or her project and explain why it is the most important. Now, I’ll put you in groups of five to have a discussion. Four group members represent scientists; one member will listen to all the scientists and ask questions. At the end of the discussion, he or she must decide who will get the money and why. Is everything clear?

Ss: Yes.

T: And following the situation, there are some useful expressions. You can use them to express your intentions and wishes. Let’s go through them together before your discussion.

(Teacher and the students go through the expressions. After that, teacher puts the students in groups of five and gets them to prepare for a few minutes. At the end, teacher asks one or two groups to report their work to the rest of the class.)

Step IV Summary and Homework

T: In this class, we’ve mainly talked about scientific achievement. Centering on this topic, we did some listening and speaking. This way, we’ve learnt more about science and scientific achievement. Moreover, we’ve learnt some useful expressions to express intentions and wishes, such as “If I got the money I would…;My plan is to…;”(Teacher writes them on the blackboard.)After class, try to practise using them and preview the reading part. So much for today. Goodbye, everyone.

Ss:Goodbye, Mr/Ms…

The Third Period Grammar

Teaching Aims:

1. Learn the Grammar--- Word formation (I)

2. Study the ways of forming a word and enlarge students’ vocabulary.

3. Enable students to use context clues and what they know about word parts to guess the meaning of new words.

Teaching important points:

The ways of forming a word.

Teaching difficult points:

How to guess the meaning of a new word.

Teaching methods: Explaining and practising

Teaching aids: 1. a projector 2. a computer

Teaching procedures:

Step I Lead in

T: Good morning afternoon, class!

Ss: Good morning afternoon,Mr/Ms…

T: This week we are learning Unit 11 Scientific achievements .Now pay attention to the two words. Will you please tell me how the two words are formed?

S1“Scientific”is the adjective form of” Science”.

S2:“Achievement “ is the noun form of “achieve”.

T: Observe them carefully; can you explain how they are formed?

S3:” Science” is a noun, if we add –fic to it, then we get its adjective.

S4: “achieve” is a verb. If we add –ment to it, we get its noun.

T: Excellent ! That is how the two words are formed. The basic part of any word is the root; to it, you can add a prefix at the beginning and/or a suffix at the end to change the meaning. For example, in the word "unflattering," the root is simply "flatter," while the prefix "un-" makes the word negative, and the suffix "-ing" changes it from a verb into an adjective (specifically, a participle).This is the grammar we are going to learn in this class.(Show Word Formation on the powerpoint.)

Step II Grammar

Ask students to observe the given words carefully and find out how words are formed.

T: How do learners improve their vocabulary? There are no super shortcuts to vocabulary, but there are various forms of support. Here is one example. Increasing your vocabulary is so important that you just can't forget about it. Don't bury your head in the sand. OK.. Please look at the following words and tell how they are formed. (Show the following words on the PowerPoint.)

affix

infix

prefix

suffix

Teacher explains the following.

T: What do these words (nouns) have in common?

Ss: All of them contain the root “fix”.

T: Well, they do have a number of things in common. Let's settle for the most obvious, the 'fix' at the end. So if we split them, this is what we get

af + fix

in + fix

pre + fix

suf + fix (These will be shown on the PowerPoint)

T: What does 'fix' mean?

Ss: Fix means attach to, fasten, stick, glue.

T: What about 'af' , 'in' , 'pre' , 'suf' ? in' and 'pre' are understandable, aren't they ?

'in' a room, 'in' a sentence, 'in' a word.

'pre' means before like in pre-war, pre-school, premature.

So what do infix and prefix actually mean? infix - to attach something inside (a word).prefix - to attach something at the beginning of (a word)

What about 'af' and 'suf'?

That's a bit more difficult to explain. 'af' is actually from the beginning the Latin word 'ad', and the meaning is the same as the English word add. Add 4 and 5 and you get 9.

'suf' is the Latin word 'sub', like in submarine, subway, suburb. The meaning is under, after (outside).

Why have the d in 'ad' and the b in 'sub' changed into f?

The reason is really quite simple. 'adfix' and 'subfix' are difficult to pronounce. There is economy in everything! You simply leave out the d and the b, but in order to mark their existence the words are spelt with an extra f .

So what do affix and suffix actually mean?

Ss: affix - to attach something to (a word)

suffix -to attach something at the end of (a word)

T: We have now fixed the fixes, haven't we? affix - something you add (stick) to a word

There are three kinds of affixes:

added inside the word - infix

added at the beginning of the word - prefix

added at the end of the word – suffix

Ss: What's this good for then?

T: Well, there are thousands of words with prefixes and suffixes. The infixes are fewer and less useful to you.

The English vocabulary basically consists of words of Latin and Germanic origin. There are prefixes in both groups.

If you know the basic meaning of a prefix or a suffix you can often 'guess' the meaning of an English word. There are a limited number of Latin prefixes and suffixes. If you learn the meaning of them, and learn to recognize them in English words, you will increase your vocabulary much faster.

Here are some of the most common Latin prefixes (for the meanings of the Latin roots, look up the words in a good dictionary): (Show the following on the PowerPoint.)

ab

(away) abstain, absent, absolve

ad

(to) adverb, advertisement, advance, adjoin

in /il-/im-/ir-

(not) incapable, indecisive, intolerable , illegal, impossible, irrugular

inter

(between, among) international, interaction interdependent, interprovincial

pre

(before) prerecorded, preface prefer

post

(after) postpone, postscript, postwar

sub

(under, not quite) subsoil, subscription, suspect ,subway, subnormal

trans

(across, to a changed state) transfer, transit, translate, transport ,transform

Step III Practice

T: Are you ready for some exercises? Open your books and look at Page6. Let’s do the exercises. Let’s do Exercise 1 first .How are these words formed? (Or show the following words on the PowerPoint).

international= inter-+national telephone= tele-+phone

mankind=man+kind broadband= broad+band

extremely=extreme+-ly manned= man+ -ed

hi-tech= high+technology email= electronic mail

IT= information technology CSA= Chinese Space Agency

S1:I think international and telephone are formed in the same way. We add prefix inter- to national and tele- to phone.

T: Good! What about the others?

S2: Mankind and broadband are formed in the same way. Each is made up of two words.

S3:Extremely and manned are formed by adding a suffix.

S4:Hi-tech is the shortened form of high technology and e-mail is the shortened form of electronic mail.

S5: IT stands for information technology. We use the first letters of the two words to form a new one .We use the first letters of Chinese Space Agency to form the word CSA.

T;Well done .So we know that words are formed in these ways. When you come across a new word, you can easily guess the meaning. Ok ,let’s come to Exercise2.

Deal with the rest of exercises in the same way.

Step IV Exercises( workbook)

T: After doing theses exercises I’m sure you have a better understanding on word formation. I hope this will help you to improve your vocabulary. When you come across a new word, try to guess its meaning in this way. Good luck to you! Today’s homework Finish all of the Vocabulary and Grammar exercises on the workbook That’s all for today.
