五种基本句型——主系表结构
主（语）＋系（动词）＋表（语）
主语.主语是五种基本句型都具备的。
从位置上来看.主语一般在句子开头.也就是一个句子的 “头把交椅”。
从意义上理解.主语一般是一个句子的“陈述对象”.后面的一切都是针对主语来说的。
主语一般是名词或代词（当然还有其他.这里暂且详细讨论）
系动词是联系动词的简称.顾名思义.它是起到联系作用的动词.是连接主语和表语的。系动词的数量是有限的.常见的只有十来个.我们把它们分成四组.这样有助于我们记忆系动词：
一、 be动词类： am、 is 、are 、was 、were
二、 表示变化类：become、 get 、 turn 、 grow 、go
三、 感官动词类: 眼（look ）耳(sound)鼻(smell)舌(taste)身(feel)
四、 表示延续性的动词 ：remain 、stay 、keep
表语
从位置上来讲.它总是在系动词后面（系动词和表语关系甚为紧密.没有系动词.就没有表语：没有表语.就没有系动词。
二从意义上讲.表语通常是来说明主语的性质、特征的。表语通常是由形容词、介词短语、名词、代词、动词不定式、doing 等来充当。
上面就是对主系表结构的简要介绍.其中.系动词是主系表结构的核心.它是这个结构的标志.看到了系动词.也就能立刻判断出句子的结构是主系表.因此.记住系动词非常重要。
