要学好英语，首先要了解句式结构。
英语中有四种基本的句式：陈述句、祈使句、疑问句和感叹句。
陈述句是对事实、安排或观点进行声明或陈述。

I thought you might have invited her over.我以为你可能已经邀请她过来了。
祈使句是发出命令有时是要求的一种句式。祈使句中一般没有主语，you是隐含的主语。祈使句以句号.
或感叹号结尾。

疑问句就是提出问题的句式。
疑问句中，助动词位于主语前面，而主语后则跟着主动词例如：Are you coming..?。
疑问句以问号结尾。

陈述句或祈使句中进行了强调。

主从复合句中含有一个独立的从句，且至少有一个。两个从句由一个从属连词如which, who, although, despite, if, since等连接起来。My daughter, who was late for class, arrived shortly after the bell rang.我女儿课迟到了，铃声响了一会才到。
