■as 引導時間狀語從句表示“當……的時候”“在……期間”時,該從句的謂語通常是那些表示動作意義的動詞,而不能是be(是、在), have(有),like(喜歡),belong(屬于)等表示狀態或靜態意義的動詞。 我打算去郵局。——當你在郵局的時候,請幫我買幾張郵票好嗎? 誤:I’m going to the post office.—As you are there, can you get me some stamps? 正:I’m going to the post office.—While you are there, can you get me some stamps? ■正因為 as 引導時間狀語從句表示“當……的時候”“在……期間”時,從句的謂語不能是表示狀態或靜態意義的動詞,所以當下面第一句變為第二句這樣的狀語從句時,不能再用 as,而應用 when: As a student he had known great poverty. =When he was a student he had known great poverty. 他當學生時,經歷過很貧困的生活。 ■但是,當 as 引導原因狀語從句時,其謂語動詞可以是狀態或靜態動詞。如: As there was very little support, the strike was not successful. 由于支持的很少,罷工未獲成功。 As I was anxious to please him, I bought him a nice present. 因為我急于討好他,我給他買了一件精美禮品。 As there isn’t anything more to do, I may as well go home early 既然這里沒有別的事要做,我還不如早點回家。 |
