T: Then look at this sentence“He got interested in two theories explaining how cholera killed people.”Why should we use“explaining”here? S: It is also used as an attribute.We can change this sentence into another form: He got interested in two theories which explained how cholera killed people. T: How about this sentence“Only if you put the sun there did the movements of the other planets in the sky make sense.” S: 這句話的意思是: 只有當(dāng)你把太陽放在中心位置上, 天空中其他行星的運(yùn)動才能說得清楚。這是一句倒裝句。因?yàn)閛nly從句放在句首, 句子要用部分倒裝結(jié)構(gòu)。 T: Can you give us more examples? S: Only by studying hard can we learn English well. Step 5 Consolidation T: We have just learned some words, phrases and some sentence structures.Do you have any other difficulties?Now look through the passages to understand more and find out your own puzzles. (The students should be allowed to read the passages, while the teacher had better give them individual help if necessary.If there are some common problems, the teacher should explain them in the whole class.) T: If you haven’t any problems, let’s have a competition.You can choose any of the words or phrases we learned to make up some sentences.For each sentence, I will give you ten marks.The more, the better.Now, let’s begin. Ss: ... (Finally the teacher should sing highly of the winner, and encourage the others to work hard to succeed next time.) Step 6 Homework T: After class, please go over what we have learned today and make up a story in which you had better try to use as many new words and phrases in this unit as possible.Then finish the exercises on Page 4, Page 42 and Page 43. The Design of the Writing on the Blackboard Unit 1　Great Scientist Period 6　Language Focusing Difficult sentences Words and phrases 1.But he became inspired when he thought about helping ordinary people exposed to cholera. 2.He got interested in two theories explaining how cholera killed people. 3.Only if you put the sun there did the movements of the other planets in the sky make sense. 4.So many thousands of terrified people died every time there was an outbreak. 1.put forward 2.know about 3.prove 4.attend 5.ease 6.in addition 7....
