Step II Revision and Presentation
T: In the third period of Unit 4, we learned the Past Participle used as Attributeand Adverbial. Now look at these sentences. Can you tell me which past participle is used as Attribute and which is used as Adverbial?
(Show the following on the screen.)

2. Given more attention, the trees could have grown better.
3. The professor came into the classroom, followed by his students.
4. The first textbooks written for teaching English as a foreign language
came out in the 16th century.
Ss: Yes, we can.
T: Who can tell us in the first sentence what the Past Participle is sued as?
S1:I know. It is used as Attribute, modifying the noun “artists”.
T: Yes. OK. Li Lu, you try, please.
S2: I think it is used as Adverbial in the second sentence.
T：Good.
S3: It is used as Adverbial in the third sentence, too.
T: (To the rest of the class.) Is that right?
Ss: Yes.
T: Good. No problem. Now, the last sentence. Who knows?
S4: Let me have a try. I believe it is used as Attribute. It modifies “ the first
textbooks”.
T: (Ask another student.) Do you agree with him/her?
S5: No, I don't think so. I think it is used as Adverbial.
T: Yeah, now, we have two different opinions. which one is correct? Whose opinion do you agree with?
Ss: The first answer is correet. It is used as Attribute, not Adverbial.
T: Why?
Ss: Because it modifies the word, “textbooks”.
T: Good. It is used as Attribute. I agree with the first student.
Step III Explanation
T: We know that the Past Participle can be used as Adverbial. Now look at these sentences on the blackboard.
(Teacher writes the following on the blackboard.)
1. Don't speak until spoken to.
2. Given more time, we could do the work much better.
3. Destroyed by the earthquake, the house had to be rebuilt.
T: What are these past participle used us?
Ss: They are all used as Adverbial.
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?
Sb: I'd like to. “Don't speak until you're spoken to. ”
T：Good. Please sit down. What about the second sentence? Who knows?
Sc: I know. If we were given more time, we could do the work much better.
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.
