8. 什么叫从句,谁能给我写几个从句 1，从句的作用可以说就是把两句话并成一句话。
2 。每个句子都会有，也只能有一个主语和谓语动词。如果将两句话并成一句话，那就会有两个主语和谓语动词，那怎么办呢？就要将其中的一句变成“从”句，用一个连接词连接主句和从句。
如，
本来应该是 1)It was a rainy day.
2)I went home that day.
就是把这两句合起来，第一句的主语是 It ，动词谓语是was；第二句的主语是I，动词谓语是went.我们要把两句合成一句，就只能有一个主语和谓语，就要把其中的一句变成从句，并用一个连接词连接。It was a rainy day when I went home.后面的 when I went home变成了整个句子的一个时间状语，是整个句子的一个部分，所以找主语和谓语是，I和was是整个句子的主语和谓语。
