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。

Whilee) _______ I was waiting for the bus, a stranger asked me for directions.1. When2. While文章正文：When and while are commonly used to talk about actions or events happening at the same time. However, there is a slight difference in their usage."When" is used to refer to a single, specific event that happens at the same time as another event. It emphasizes the momentary coexistence of two actions.For example, in the sentence "When I was cooking dinner, my friend called," the cooking and the phone call happened simultaneously. The focus is on the coincidence of these two events occurring at the same time."On the other hand, "while" is used to describe two ongoing or continuous actions that happen at the same time. It emphasizes the duration of the actions.For example, in the sentence "While I was cooking dinner, my friend called," both the cooking and the phone call were happening over a period of time. The focus is on the actions being carried out at the same time.Now let's move on to the practice questions:1. Fill in the blanks with "When" or "While":a) _______ I was cooking dinner, my friend called.b) _______ I was watching TV, the phone rang.c) _______ I was studying, my brother came into my room.d) _______ I was reading a book, it started to rain outside.e) _______ I was walking in the park, I saw my teacher.2. Choose the correct answer and fill in the brackets:a) _______ I was doing my homework, my favorite song came on the radio.1. When2. Whileb) _______ I was driving to work, I noticed a beautiful sunrise.1. When2. Whilec) _______ I was eating breakfast, my cat jumped onto the table.1. When2. Whiled) _______ I was sleeping, my phone rang.1. When2. Whilee) _______ I was waiting for the bus, a stranger asked me for directions.1. When2. WhileIn conclusion, "when" and "while" both indicate actions happening simultaneously, but "when" emphasizes a single specific event, while "while" highlights ongoing or continuous actions. Practice using these words to improve your understanding and fluency in English.。
