　　t: yes, you're right. and we know that the past participle used as adverbial      can express different adverbials, such as: time, cause, condition, manner and      so on. do you know what the past participle in each sentence expresses? who     knows?

　　sa: the past participle in the first sentence expresses time. the second one       expresses condition. and the last one expresses cause.

　　t: very good. now, i'll give you a few minutes to discuss with your partner

　　about how to replace these past participles by using adverbial clauses.

　　t: (a few minutes later.) who'd like to try the first sentence?

　　t: ok. sit down, please. now, the last sentence. who wants to have a try?

　　s: beeause the house had been destroyed by the earthquake, it had to be rebuilt.

　　t: good.

　　(teacher writes the sentences above on the blackboard.)

　　step vi comparison

　　t: as we all know, the past participle and the present partieiple can be used as adverbial, for example: (teacher writes the following examples on the

　　blackboard. )

　　1. seen from the hill, our school looks more beautiful.

　　2. seeing from the hill, we can see our beautiful school.

　　t: look at these two sentences carefully. can you tell us the difference between       them?

　　s: the first sentence uses the past participle as adverbial while the second       sentence uses the present participle as adverbial.

　　t: good. do you know why?

　　s: because the subject in the first sentence is “our school”, but in the second       sentence the subject is “we”.

　　t: very good. when we are using participles, we should pay attention to the       subjects in the sentences, and the participle we use must have the same logical subject as the subject in the sentence. if the subject in the sentence receives the action, we should use the past participle as adverbial; if the subject in the sentence does the action, we should use the present participle as adverbial. do you nderstand?

　　ss: yes.

　　step v practice

　　t: look at the sentences on the screen. join each of the following pairs of

　　sentences turning one of them into a participle phrase and making other

　　necessary changes. do it in pairs or groups. example: we were disturbed by the        noise and had to finish the meeting early.

　　→disturbed by the noise, we had to finish the meeting early.

　　rewrite the sentences, using the past participle.
