We didn't reach the cinema on time because of the heavy rain yesterday

问题描述:

We didn't reach the cinema on time because of the heavy rain yesterday

复杂句……complex sentence,其实它叫复合句啦.由字面意思上解,就是由一个独立的句子在加上一个或多个从句组成.只含有一个主谓结构并且句子各成分都只由单词或短语构成的独立句子或分句叫做简单句.
你的这个句子只有一套主谓宾所以是简单句,接下来我们把它变成复杂句只需要再添加从句就好了.
We didn't reach the cinema on time是主句,原因由because of 短语连接,所以我们把because of 改成beacuse连接的原因状语从句就好,然而什么下雨?没有主语,就加个it
算了,我讲的不是很清楚,直接上句子:We didn;t reach the cinema on time,because it rained heavily yesterday.有不懂的地方,欢迎追问.
