idea后接動詞和從句的用法問題
1. 表示做某事的想法,其后要接 of doing sth作定語,一般不接不定式。如:
I hate the idea of getting old. 我討厭變老這個想法。
The idea of parachuting out of a plane terrifies me. 一想到要從飛機上跳傘,我就感到很害怕。
其后雖然不直接跟不定式,但有時可接帶連接代詞或連接副詞的不定式。如:
I have no idea of how to do it. 我不知道如何做此事。
I had no idea what to say to her. 我不知道對她說什么。
注意下面一句中idea后的不定式不是定語,而是主語:
It’s not a good idea to come between a man and his wife. 最好不要介入人家夫妻間的事。
2. idea 之后可接一個由 that 引導的同位語從句,用以說明idea的具體內容,此時的 that不能改用 which。如:
She had no idea that I was unhappy. 她不知道我不高興。
The idea that you can do this work without thinking is wrong. 你可以不動腦筋做此工作的想法是錯誤的。
但是,如果其后接的是定語從句,則可以用which來引導,此時的which在定語從句中用作主語或賓語。如:
The idea which she put forward was interesting. 她提出來的想法很有趣。
3. 后接that引導的從句時,不用介詞 of;接續(xù)疑問詞引導的從句時,可用介詞of(也可省略)。如:
Have you any idea (of) when he will come? 你知道他什么時候來嗎?
This will give you some idea (of) what relativity means. 這會使你對相對論的意義有所理解。
