原因状语从句练习题及解析答案详解
原因状语从句练习题及解析答案详解原因状语从句是表达某件事情发生原因的从句，由because，since，as等引导；目前在英语中是比较常用的一类从句。
下面将为大家列举一些原因状语从句练题并附上详细解析答案，希望对大家在研究中有所帮助。
练题2. We must obey the traffic rules _____________ we may cause accidents.3. I didn't go swimming this afternoon ____________ I was busy.4. This is _________________ the little girl burst into tears.5. The reason why he is late is ______________ his car broke down.答案详解1. As指"由于"，表示原因，因此所填的状语从句为原因状语从句，因而可以形成“因果关系”，完整的句子为：“由于他病了，他没有来参加晚会。
”2. 一个句子中只有一个主语和一个谓语，在前面的句子中已经有了谓语，所以只能用连词“or”“and”“but”等来连接两个句子。
因此题目应填因果关系连词because。
完整的句子为：“我们必须遵守交通规则，因为否则我们可能会造成事故。
”3. as是一个比较平常的原因状语从句的引导词，as引导的原因状语从句，常作句子的前置状语。
表示由于，因为；它所在的句子通常已经表示了结果。
完整的句子为：“我今天下午没去游泳，因为我很忙。
”4. 笑是因为快乐，而哭是因为悲伤。
本句话含有转折关系，故可选but，表示转折；句意为“这就是为什么小女孩会哭"。
5. 这个句子又可以按照"why"型原因状语从句来处理，即后面宾语从句的结构就是“ “the reason” + “why” + “主语” + “谓语””，因此which是不可用的，答案应为：the reason why，意为“他迟到的原因是因为他的车坏了。

解析：本题考查原因状语从句。
because用来引导原因状语从句，表示“因为”。
句子表达我喜欢读书的原因是能让我学到很多东西。
选项A“so”表示“所以”，是结果关系；选项B“but”表示“但是”，是转折关系；选项D“and”表示“和、并且”，是并列关系，都不符合句子逻辑。

4. My mother cooked a big dinner ____ my father was coming back.A. whileB. asC. becauseD. since答案：C。
解析：句子的意思是我妈妈做了一顿丰盛的晚餐，原因是我爸爸要回来了。
because强调原因。
