Now please complete each sentence and discuss your answers with your partner. At the end, well check the answ
11、ers together.Suggested answers :1. killer 2. alarming 4. citizen 5. responsibility 6. representatives 7. suffering 8. willingness (Then go on with the second part.)T: Now, lets do the second part. First, you should study the words in the boxcarefully. Then put them into two categories. At the end, s
12、tate your reasons. Are you clear?Ss: Yes.T: You can begin now. Work in pairs.(After a while, teacher checks their work. )Suggested answers:Adverbs: really, unfortunately, absolutely, especially, successfullyAdjectives: lonely, lively, ugly, lovely, friendlyStep V Presentation(Teacher shows the follo
13、wing sentences on the screen. )1. Conferences like the Earth Summit help people understand that there exist serious problems and that there is still time to take action.2. Among the speakers was Chinas then Premier Zhu Rongji, who stressed the need for equality and fairness in the world.3. Not until
14、 we know more will we be able to improve the situation.4. Only by changing the way we live can we save the earth.5. Had I known that air conditioners cause so much pollution, I would never have bought one.6. A better understanding of the environment is necessary, as is the willingness to act.7. With
15、out international cooperation, developing countries cannot prosper, nor will sustainable development be possible.T: Now, please look at the sentences on the screen and pay attention to the word order of each sentence. In what way are these sentences different from the usual sentences?Ss: The word or
16、der is not “Subject + Verb” but “Verb + Subject” or “Auxiliary/ Modal + S + V”.(Teacher writes the structures on the Bb.)T: Yes. This kind of sentence is called Inversion, which happens in questions and in a number of other cases. Look at the sentences carefully again, paying attention to the underl
17、ined words. In the first sentence, “exist” is used after“there” to express a state for existence like“there be” structure; the second sentence begins with a preposition phrase. In these two sentences, the whole predicate verb comes before the subject. The third sentence begins with a negative adverb
18、; in the fourth sentence, “only” is placed at the beginning of the sentence with an adverbial. In these two sentences, part of the predicate comes before the subject. In most cases, an auxiliary verb or a modal verb comes before the subject and the rest of the predicate verb comes after. If there is
19、 no auxiliary or modal, do, does or did should be added. Can you understand?Ss: Yes.T: Then look at the fifth sentence and change it into another sentence with the same meaning, which begins with “if”.Ss: If I had known that air conditioners cause so much pollution, I would never have bought one.T:
20、Quite right. In some special forms of unreal conditional clauses, when “if” is left out, part of the predicate like had, should, were should conies before the subject. That is to say, inversion can be used instead of “if”. Are you clear about that?Ss : Yes.T: Next, look at the last two sentences, To
21、 avoid repetition,“as” and “ nor” are placed at the beginning of the sentences which say that people(or thing or situation) are the same as others that have been mentioned. In this case, the structure “as/nor+ auxiliary/modal/do(does, did) + subject” should be used. Besides,“neither” and “so” can be
22、 used like “nor”and “as”. Is that clear?(Bb: as/so; neither/nor + aux./mod. / do( does. did) + subject )Ss: Yes.T: OK. Now， lets change them into the usual word order sentences. Wang Xia ,you try the first.Ss: It is a special sentence pattern like“ There be” structure. “exist” can only come after “t
23、here”.T: Yes. Sit down, please. Then the next sentence.Ss: Chinas then Premier Zhu Rongji was among the speakers, who stressed the need for equality and fairness in the world.T: S3: We will not be able to improve the situation until we know more.S4: We can save the earth only by changing the way we
24、live.S5: If I had known that air conditioners cause so much pollution, I would never have bought one.S6: A better understanding of the environment is necessary, and the willingness to act is necessary, too.S7: Without international cooperation, developing countries cant prosper. Sustainable developm
25、ent will not be possible either.Step VI Grammar PracticeT: Well, now please turn to Page 70. Look at the first part ,Grammar: Rewrite the following sentences, beginning with the underlined part.

Only with better education will people be able to build a better society in harmony with nature.7. Seldom do we t
28、hink of the small changes that we can do to make a big difference.8. Never have I realised that water is so precious.(Then teacher deals part in Grammar.)T: All right. Now lets come to the second part. Complete the following sentences using the words in the box: so, neither, nor, as. At the same tim
29、e, you should pay attention to the verb form before the subject. First do it individually. Then check your answers with your partner. At the end, Ill ask some of you to read the whole sentence.Suggested answers: 1. so/as have 2. neither/nor should3. so/as do 4. so/as am 5. neither/nor do 6. so/as is
30、 7. neither/nor 8. neither/nor can9. so/as can (After checking the answers, teacher says the following. )T: From these sentences, we know the verb-form after “so, neither, nor, as”should be the same as the verb-form after the first subject. The person andnumber should agree with its own subject. Is
31、that so?Ss: Yes.Step VI Summary and HomeworkT: Now, lets look at what weve learnt in this period. At the beginning of class, we revised the contents of the last class. Then we did some exercises to further study some learnt words in the text. At the end, we learnt the usage of Inversion. To master i
32、t better, we also did some exercises. But thats not enough. I hope you can practise more after class. The more you practise, the greater progress you will make. So much for this period. See you tomorrow.Ss: See you tomorrow !Step VIII The Design of the Writing on the Blackboard Unit 9 Saving the earth The Third Period I. Word study II. Grammar: Inversion 1. There exist/be. 2.
