Step 1 课前自学

一、知识梳理

Activity 1

1. Look at the sentences from the reading passage and answer the questions.

a. Having seen quite a few productions of Hamlet and read the play many times, I was full of confidence – until the Peking Opera came to town!

b. ... seeing the main characters come on stage, I was surprised!

(1) In sentence (a), who had seen quite a few productions of Hamlet and read the play many times? (Answer: I) In sentence (b), who saw the main characters come on stage? (Answer: I)

(2) Is this structure used more often in spoken or written English?

(Answer: It’s used more often in written English.)

2. Compare them with the following sentences and answer the questions.

c. Since I had seen quite a few productions of Hamlet and read the play many times, I was full of confidence – until the Peking Opera came to town!

d. ... when I saw the main characters come on stage, I was surprised!

(3) What is the difference between the two groups of sentences?

(Answer: The first group uses present participles as adverbial while the second group uses adverbial clauses.)

(4) Why does the author choose to use sentences (a) and (b) in the reading passage?

(Answer: Because the sentences from the reading passage are more concise and formal.)

Now look for more sentences with this structure in the reading passage.

1)作时间状语

Seeing the police, he made a run for the exit. (一看到警察，他就朝出口奔去。）

2)作原因状语
