高中英语状语从句分类练习题50题(带答案)1. I will call you ____ I arrive in Beijing.A. as soon asB. whileC. sinceD. until答案解析：A。
本题考查时间状语从句。
as soon as表示“一……就……”，句意为我一到达北京就给你打电话，符合语境。

2. She was reading a book ____ her mother came in.A. whenB. whileC. asD. after答案解析：A。
when在这里表示“当……时候”，从句的动作可以是短暂性的，当她妈妈进来这个短暂动作发生时，她正在读书。
while 强调主句和从句动作同时进行，且从句的动作是持续性的，her mother came in是短暂动作，所以不选while。
as表示“一边……一边……”或者“随着”，不符合语境。
after表示“在……之后”，语义与原句不符。
3. ____ he was a child, he liked to ask questions.A. AsB. WhenC. WhileD. Since答案解析：B。

since表示“自从”或者“因为”，不符合语境。

高中时间状语从句及练习(含答案)
状语从句状语从句在句中作状语，修饰主句中的动词、形容词或副词等。
状语从句放在主句之前时，常用逗号分开;放在主句之后，一般不用逗号。
状语从句按其意义和作用可分为时间、原因、地点、条件、让步、目的、结果、方式、比较等9种。
1.时间状语从句时间状语从句表示主句动作发生的时间，主要由when，while，as ; before, after; till (until); once, by the time, as soon as, no sooner ... than和hardly ... when及名词词组the moment等引导。
1) when“在……的时候”; while “在……期间”; as “正当……的时候”when意为“在……的时候”，强调“特定时间”。
When spring came, he felt like a trip.When he was eating his breakfast, he heard the doorbell ring.说明：连词when在状语从句中还有如下几种含义：①表示突然发生的事，含义为“（正在……时）忽然”。
I was just coming along to see you when I ran into Wilson.I had been working a couple of months when I had a letter from Jane.②表示过早发生某事，意为“（还没……）就”。
此含义有时可用before代替。
I hadn’t been reading for half an hour when I heard steps outside.我刚读了不到半个小时就听到外面有脚步声。
I had been there little more than a week when I set to work in earnest.③表示“在……的情况下”，常可译为“虽然”，“既然”，“如果”。

高一英语时间状语从句单选题50题1. I was reading a book ____ the teacher came into the classroom.A. whenB. whileC. asD. since答案：A。
解析：when可表示在一个动作发生时，另一个动作突然发生。
此句表示当老师走进教室这个动作发生时，我正在看书这个动作正在进行，强调突然性。
while通常表示两个动作同时进行，强调动作持续的时间段，这里强调的不是同时进行的时间段，所以B不正确。
as表示两个动作同时进行，强调一边一边，这里不符合语境，C错误。
since表示自从，引导原因状语从句或时间状语从句表示从过去某时开始，与本题语境不符，D错误。
2. ____ we were having a PE class, it began to rain heavily.A. AsB. WhenC. WhileD. Because答案：C。
解析：while强调在一个较长的动作进行过程中，另一个动作发生。
这里我们正在上体育课是一个持续的动作过程中，开始下大雨这个动作发生了。
as虽然也表示同时进行，但更强调两个动作的同时性和平行性，这里强调的是在体育课进行过程中下雨，所以A不太合适。
when主要强调一个动作发生时另一个动作突然发生，这里不是突然性，B错误。
because表示原因，不符合本题语境，D错误。
3. He was singing ____ he was taking a shower.A. whenB. whileC. asD. after答案：B。
解析：while强调两个动作同时进行，这里唱歌和洗澡这两个动作是同时进行的。

高一英语状语从句练习题40题(答案解析)1. I was reading a book ____ my mother came in.A. whenB. whileC. asD. since答案解析：A。
when在这里表示“当……的时候”，从句中的动作可以是短暂性的，也可以是持续性的。
在这个句子中，“my mother came in”是短暂性动作，“I was reading a book”是持续性动作，这种情况下when是合适的。
while引导时间状语从句时，从句中的动作一般是持续性的，as表示“一边……一边……”或者“随着”，since表示“自从”，在这里不符合语境。
2. ____ he was a child, he has been interested in music.A. SinceB. BeforeC. AfterD. Until答案解析：A。
since表示“自从”，在这里引导时间状语从句，从句用一般过去时，主句用现在完成时，表示从过去某个时间开始一直持续到现在的动作或状态。
Before表示“在……之前”，After表示“在……之后”，Until表示“直到”，都不符合句子的逻辑。
3. The moment I ____ the news, I will tell you.A. will getB. getC. gotD. am getting答案解析：B。

所以这里用get。
4. She didn't go to bed ____ she finished her homework.A. untilB. sinceC. whileD. if答案解析：A。

高中英语状语从句练习题20题带答案1. I will call you ______ I arrive at the airport.A. as soon asB. whileC. untilD. since答案解析：A。
本题考查时间状语从句的引导词。

高一英语状语从句练习题40题(带答案)
高一英语状语从句练习题40题(带答案)1. I was reading a book ______ my mother came in.A. whenB. whileC. asD. since答案解析：A。
when在这里引导时间状语从句，表示“当……的时候”，从句的动作“my mother came in”是短暂性动作。
while引导时间状语从句时，从句中的动词一般是延续性动词。
as强调两个动作同时进行，常译为“一边……一边……”，在这里不符合语境。
since表示“自从”，引导原因状语从句或时间状语从句（ 表示自从某个时间点以来），与本题语境不符。
2. ______ he had finished his homework, he went out to play.A. As soon asB. WhileC. BeforeD. After答案解析：A。
As soon as表示“一……就……”，强调两个动作的紧密衔接，他一完成作业就出去玩了。
While引导时间状语从句时，从句中的动作通常是延续性的，这里“finished his homework”是短暂性动作，不符合。
Before表示在某个动作之前，若选Before则语义为在完成作业之前就出去玩了，不符合逻辑。
After表示在……之后，虽然语义上可行，但不如As soon as能体现出动作的紧凑性。
3. The moment ______ I saw her, I recognized her.A. whenB. whileC. asD. since答案解析：A。
The moment相当于as soon as，在这里引导时间状语从句，when也可以引导时间状语从句，表示“当……的时候”，在这里可以替换The moment。
while引导时间状语从句时，从句中的动词应为延续性动词，这里“saw”是短暂性动词，不符合。
as强调两个动作同时进行，这里不强调同时进行。
