高一英语状语从句单选题20题
1. I was doing my homework ______ my mother was cooking in the kitchen.
A. while
B. when
C. as
D. since
答案：A。

本题考查时间状语从句中“while”“when”“as”的用法区别。

“while”强调两个动作同时进行，主从句都用进行时态；“when”既可以表示动作同时发生，也可以表示一个动作在另一个动作正在进行时发生；“as”强调两个动作同时发生，且有伴随的意思；“since”表示“自从”，不符合题意。

本题中“我在做作业”和“妈妈在厨房做饭”两个动作同时进行，都用进行时态，所以用“while”。

2. ______ he came in, I was reading a book.
A. When
B. While
C. As
D. Since
答案：A。

“when”在此处表示一个动作在另一个动作正在进行时发生，“他进来”这个动作短暂，“我在读书”这个动作持续，所以用“when”。

“while”强调两个动作同时进行；“as”强调两个动作同时发生且有伴随的意思；“since”表示“自从”，均不符合题意。

3. I was just reading a book ______ she came to see me.
A. while
B. when
C. as
D. since
答案：B。

“when”表示一个动作在另一个动作正在进行时发生，“她来看我”这个动作短暂，“我在读书”这个动作持续，用“when”。

“while”强调两个动作同时进行；“as”强调同时发生且伴随；“since”表示“自从”，均不符合。

4. ______ time goes by, we become older and older.
A. As
B. When
C. While
D. Since
答案：A。

“As”表示“随着”，引导时间状语从句，符合“随着时间流逝，我们越来越老”的意思。

“when”“while”没有“随着”的意思；“since”表示“自从”，不符合题意。

5. He was playing football ______ it began to rain.
A. while
B. when
C. as
D. since
答案：B。

“when”表示一个动作在另一个动作正在进行时发生，“开始下雨”这个动作短暂，“他在踢足球”这个动作持续，用“when”。

6. If it ______ tomorrow, we will stay at home.
A. rains
B. rained
C. will rain
D. is raining
答案：A。

本题考查条件状语从句中“主将从现”的用法。

主句用一般将来时“we will stay at home”，从句用一般现在时，it 是第三人称单数，rain 要用第三人称单数形式rains。

B 选项rained 是过去式，不符合条件状语从句的时态规则；C 选项will rain 是将来时，也不符合；D 选项is raining 是现在进行时，同样不符合。

7. We'll go for a picnic if it ______ fine this weekend.
A. is
B. was
C. will be
D. has been
答案：A。

“主将从现”原则，主句“We'll go for a picnic”是一般将来时，从句用一般现在时，it 后接is 表示“是”，B 选项was 是过去式；C 选项will be 是将来时；D 选项has been 是现在完成时，均
不符合条件状语从句的时态要求。

8. If you ______ hard, you'll pass the exam.
A. study
B. studied
C. will study
D. are studying
答案：A。

依旧是“主将从现”，主句“you'll pass the exam”将来时，从句用一般现在时，you 作主语，study 用原形，B 选项studied 是过去式；C 选项will study 是将来时；D 选项are studying 是现在进行时，都不正确。

9. I'll call you if I ______ free tomorrow.
A. am
B. was
C. will be
D. have been
答案：A。

遵循“主将从现”，主句“I'll call you”将来时，从句用一般现在时，I 后接am 表示“是”，B 选项was 过去式；C 选项will be 将来时；D 选项have been 现在完成时，均不符合。

10. If he ______ time, he will come to see you.
A. has
B. had
C. will have
D. is having
答案：A。

还是“主将从现”，主句“he will come to see you”将来时，从句用一般现在时，he 是第三人称单数，have 要用has，B 选项had 是过去式；C 选项will have 是将来时；D 选项is having 是现在进行时，都不符合条件状语从句的时态规则。

11. I was late for school ______ the traffic was heavy.
A. because
B. since
C. as
D. for
答案：A。

本题考查原因状语从句的连接词。

“because”表示直接的、明确的原因，语气最强；“since”和“as”也表示原因，但语气较弱，且通常位于句首；“for”引导的是并列句，并非原因状语从句。

在此句中，“the traffic was heavy”是“我上学迟到”的直接原因，所以用“because”。

12. ______ it was raining hard, we stayed at home.
A. Because
B. Since
C. As
D. So
答案：A。

“because”引导原因状语从句，强调直接原因。

“since”和“as”语气较“because”弱，且通常置于句首。

“so”表示结果，不符合
此句逻辑。

此句中“it was raining hard”是“we stayed at home”的直接原因，用“because”最合适。

13. He didn't come to the party ______ he was too busy.
A. because
B. since
C. as
D. for
答案：A。

“because”直接阐明原因，在此句中“he was too busy”清晰地解释了“他没来聚会”的原因，是最强有力的原因表述。

“since”和“as”语气较弱且常置于句首，“for”引导的不是原因状语从句。

14. We have to put off the sports meeting ______ it is raining.
A. because
B. since
C. as
D. for
答案：A。

“because”突出直接原因，此句中“it is raining”直接导致“put off the sports meeting”，是最符合逻辑的原因表述。

“since”和“as”常用于句首且语气较弱，“for”引导的并非原因状语从句。

15. She can't go with us ______ she has a lot of work to do.
A. because
B. since
C. as
D. for
答案：A。

“because”表示明确直接的原因，此句中“she has a lot of work to do”是“she can't go with us”的明确原因。

“since”和“as”常置于句首且语气稍弱，“for”引导的不是原因状语从句。

16. ______ he is very tired, he still keeps working.
A. Though
B. Because
C. If
D. When
答案：A。

本题考查让步状语从句。

“Though”表示“尽管”，引导让步状语从句，符合题意。

“Because”表示原因；“If”表示条件；“When”表示时间，均不符合句子逻辑。

17. ______ she was ill, she still went to school.
A. Even though
B. So that
C. As soon as
D. Such that
答案：A。

“Even though”意为“即使”，引导让步状语从句，在本句中表示尽管她生病了，还是去上学了。

“So that”引导目的状语从句；“As soon as”引导时间状语从句；“Such that”并非常用的引导状语从句的词，不符合本题语境。

18. ______ difficult the problem is, we should try to solve it.
A. However
B. Whenever
C. Wherever
D. Whoever
答案：A。

“However”表示“无论如何，不管多么”，引导让步状语从句，强调程度。

“Whenever”表示“无论何时”；“Wherever”表示“无论何地”；“Whoever”表示“无论谁”，均不符合句子意思。

19. ______ much advice I gave him, he did exactly what he wanted to do.
A. However
B. Whatever
C. Whoever
D. Whenever
答案：A。

“However”修饰形容词“much”，表示“无论多少”，引导让步状语从句。

“Whatever”表示“无论什么”；“Whoever”表示“无论谁”；“Whenever”表示“无论何时”，都不符合本句句意。

20. ______ bad the weather is, we won't put off the sports meeting.
A. Though
B. However
C. Even if
D. As if
答案：B。

“However”修饰形容词“bad”，表示“无论多么糟糕”，引
导让步状语从句。

“Though”引导让步状语从句时，不能修饰形容词；“Even if”意为“即使”；“As if”意为“好像”，均不符合句子逻辑。
