Step II Revision and Lead -in

T: Yesterday we read a passage about the Earth Summit and some of the major

problems facing the world. Through the passage we know at the Earth Summit, representatives from more than one hundred countries discussed some of the most important problems facing our planet. Up to now, several Earth Summits have been held and much progress has made. Can you tell me in which city the 2002 Earth Summit was held?

Ss: Johannesburg in South Africa.

T: Do you remember one of the main themes of the 2002 Earth Summit？And what was it?

Ss: Yes. It was sustainable development, or the question of how we can continue

developing the world without damaging the environment.

T: What are the three biggest killers in the world?

Ss: Contaminated drinking water, poor sanitation and air pollution.

T: What other problems did the speakers speak about?

Ss: Poverty, war and violence.

T: What did China's then Premier Zhu Rongji stress?

Ss: The need for equality and fairness in the world.

T: How can we save the earth?

Ss: By changing the way we live.

T: What is the key to the future?

Ss: Education.

T: Quite right. The Earth Summit is not just about problems, but also a place to find solutions for the future. We should believe that the future of our planet must be more and more beautiful with the whole world's effort, Today, we'll learn to use the language points appearing in the passage. First, word study. Then Grammar-Inversion.

Adjectives: lonely, lively, ugly, lovely, friendly

Step V Presentation

(Teacher shows the following 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 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. Without 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 order 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 underlined 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; 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 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: 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 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 used like “nor”and “as”. Is that clear?

(Bb: as/so; neither/nor + aux./mod. / do( does. did) + subject )

Ss: Yes.

T: OK. Now， let's 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 “there”.

T: Yes. Sit down, please. Then the next sentence.

Ss: China's 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 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 can't prosper. Sustainable development will not be possible either.

following sentences, beginning with the underlined part. First study the example, and then complete each sentence below. A few minutes later, I'll check
