1、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
2、、 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。 练习找出下面句子中的主语、系动词及表
