【名词性从句练习题(含答案)经典】在英语语法中,名词性从句是一个非常重要的知识点,它在句子中可以充当主语、宾语、表语或同位语。掌握好名词性从句的用法,有助于提高阅读理解能力和写作水平。以下是一些经典的名词性从句练习题,附有详细解析,帮助大家更好地理解和运用这一语法点。
一、选择题
1. I don’t know ______ he will come tomorrow.
A. that
B. if
C. whether
D. what
答案:B / C
解析:当主句是“don’t know”时,后面接的从句如果是表示疑问的内容,可以用“if”或“whether”,两者在大多数情况下可以互换。但要注意,“whether”常用于正式场合,而“if”更口语化。
2. The teacher asked me ______ I had finished my homework.
A. that
B. if
C. whether
D. what
答案:A
解析:这里从句是一个完整的陈述句,不涉及疑问,因此应使用“that”引导宾语从句。注意:“if”和“whether”不能用于陈述句引导的从句。
3. She is not sure ______ she should go to the party.
A. if
B. whether
C. that
D. what
答案:B
解析:当主句是“not sure”时,后面接的是一个疑问句内容,因此使用“whether”更合适。虽然“if”也可以用,但在这种结构中,“whether”更为常见。
4. The problem is ______ we can solve it in time.
A. if
B. whether
C. that
D. what
答案:C
解析:此句中,从句“we can solve it in time”是一个完整的陈述句,所以应该用“that”引导表语从句。注意:“if”和“whether”只能用于疑问句引导的从句。
5. Do you remember ______ she left?
A. when
B. where
C. why
D. how
答案:A
解析:此句中,从句“she left”是一个完整的句子,但前面有疑问词“when”,所以用“when”引导宾语从句。

正确:She asked me if I had seen the movie.
解析:当主句是“asked”时,后面的从句是疑问句,应使用“if”或“whether”。
3. The fact is that he is honest.
