九年级英语时间状语从句练习50题(带答案)
九年级英语时间状语从句练习50题(带答案)1. I was reading a book ______ my mother came back home.A. whileB. whenC. asD. since答案：B。
解析：本题考查when引导的时间状语从句。
when引导的从句中的动词既可以是短暂性动词也可以是延续性动词。
在这个句子中，came back是短暂性动词，when表示“当……的时候”，强调在某个时刻发生某事。
while引导的从句中动词应为延续性动词，这里came back是短暂性动词，所以A选项错误。
as表示“一边……一边……”或者“随着”，在此句语境不符，C选项错误。
since表示“自从”，语义和句子不符，D选项错误。
2. ______ we were having a PE class, it began to rain.A. WhenB. WhileC. AsD. Because答案：A。
解析：本题考查when引导时间状语从句。
when引导时间状语从句时，表示“当……的时候”，从句中的动作和主句中的动作可以同时发生，也可以先后发生。
这里“我们正在上体育课”和“开始下雨”是两个同时发生的动作，when适用。
while强调主句和从句的动作同时进行，且从句中的动词应为延续性动词，这里begin不是延续性动词，B选项错误。
as表示“随着”或者“一边……一边……”，不符合句子语境，C选项错误。
because表示原因，与句子逻辑不符，D 选项错误。
3. The students stopped talking ______ the teacher entered the classroom.A. whenB. whileC. asD. if答案：A。
解析：本题考查when引导的时间状语从句。
when引导从句时，从句中的动词enter是短暂性动词，when表示“当……的时候”，当老师进入教室的时候学生停止说话，符合语境。

高中英语时间状语从句结构练习题20题(答案解析)
高中英语时间状语从句结构练习题20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引导时间状语从句时，从句的动作可以与主句的动作同时发生，也可以先于主句动作发生。
在此句中，“我正在读书”这个动作正在进行时，“妈妈进来”这个动作突然发生，这种情况下用when。
while强调主句和从句的动作同时进行，通常从句用进行时态；as表示“一边……一边……”或者强调两个动作同时进行，并且有随着的意思；since表示“自从……以来”，引导原因状语从句或者时间状语从句（表示从过去某个时间点开始一直持续到现在），在这里不符合语境。
2. ____ he was young, he liked to play football.A. WhenB. WhileC. AsD. Until答案解析：A。
when可以表示在某个特定的时间点或者时间段内，“当他年轻的时候”，表示在他年轻这个时间段内，他喜欢踢足球。
while 强调同时进行，在这里语义不符；as有多种含义，但在此处表示“当……时”没有when简洁准确；until表示“直到……”，与句子意思不符。
3. She didn't leave ____ I came back.A. whenB. whileC. asD. until答案解析：D。
until表示“直到……才”，句子的意思是“直到我回来她才离开”。
when、while、as都没有这种“直到……才”的语义。
4. ____ we were walking in the park, we saw a beautiful bird.A. WhenB. WhileC. AsD. Since答案解析：C。
as表示“当……时”，强调两个动作同时进行，并且有随着的意思，“当我们在公园散步的时候（随着我们在公园散步这个动作的进行），我们看到了一只美丽的鸟”。
