五种基本句型-主系表结构
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。
练习 找出下面句子中的主语、系动词及表语，并指出主语和表语分别是由什么词性或词类来充当的。 1 Tom is a student. 2 He is fat. 3 I am tired . 4 We are students. 5 The bag was lost . 6 The boy was foolish . 7 They were kind. 8 She is in the room. 9 The books are on the desk. 10 Snow is white. 11 Kate was here yesterday. 12 My father became a teacher in 1978. 13 The weather gets hot in summer. 14 She looks beautiful. 15 The flower smells good. 16 We were very happy. 17 You are right. 18 The soup tastes delicious. 19 The chair is yours. 20 The children are asleep. 21 The story is interesting. 22 He feels better today. 23 The leaf turns green. 24 I stayed awake all the night. 25 The weather still remained cold in April. 26 The little girl is six. 27 My work is to look after the baby.
