按照句子的结构来分，英语的句子有以下三种类型： 1、简单句：简单句只有一个主语（或并列主语）和一个谓语动 词（或并列谓语动词）。如：My brother and I go to school at half past seven in the morning and come back home at seven in the evening. 2、并列句：并列句由并列连词或分号“；”把两个或两个以上 的简单句连在一起构成。如：It is late, so we must hurry. 3、复合句：复合句由一个主句和一个或一个以上的从句构成。 如： If we want to keep fit, we must always remember that prevention is better than cure. 从以上并列句和复合句的例句来看，我们不难看出它们实际上 是由几个简单句通过并列连词或从属连词连接起来的。因此，只 要我们掌握了简单句的几种基本句型，我们就可以通过在句中寻 找起连接作用的连词来分析复杂的句子。
