主系表结构 There be句型,1,一、主系表结构,主谓宾=主语+实义动词+宾语，be是系动词，不能用于主谓宾中。 主系表=主语+系动词(最常见的是be，还有“五感”feel、look、sound、smell、taste和其它动词如become、grow等）+表语（名词、代词、形容词、时间地点副词、介词短语、表语从句等）。,2,如I am a boy.这句话中没有宾语，属于主系表，I是主语，系动词am是谓语动词，a boy是表语，系动词和表语合起来作谓语。由此可见在主系表中，谓语谓语动词；而在主谓宾中，谓语=谓语动词，如I love my parents. 总之，系动词和宾语是不共戴天的仇人，誓不两立。系动词后面接的是表语，而宾语前面接的是谓语。,3,所谓主系表结构就是英语句子中的主要成分是主语、系动词和表语。主要用以说明主语的特征，状态，身份等。,定义,主系表（S+V+P）： 1. 主语（ Subject ） 2. 系动词（ Link verb ） 3. 表语（ Predicative）,4,所谓主系表结构就是英语句子中的主要成分是主语、系动词和表语。主要用以说明主语的特征，状态，身份等。 1. 主语（ Subject ）：主语是一句话的中心，表示所说的是谁或是什么，其位置一般放在句首。英语中主语一般不省略。主语主要由名词、动名词、代词或起名词作用的短语或从句来充当。 例如： Li Lei is a Chinese boy. （ Li Lei 是名词，作主语。） He is from England. （ He 是代词，作主语。） Feeding the birds is my hobby. （“ Feeding the birds ”是动名词短语，作主语。） What she said is right. （“ What she said ”是从句，作主语。,5,2. 系动词（ Link verb ）：系动词本身有一定的词义，但不能独立作谓语，必须和句子中的表语一起构成谓语。简单地说，将主语和表语联系在一起，并构成一个完整句子的动词就叫做系动词。目前学到的系动词有 be ， feel ， look ， sound ， taste ， smell 等。 例如：This flower is beautiful. I felt very tired. You look worried. It tastes delicious.,6,常见的系动词,（1）表示特征和存在状态的 be, feel, look, smell, taste, sound. （2）表示状态延续的 keep （3）表示状态变化的 become, get, turn, go, come,7,3. 表语（ Predicative ）：表语是用来说明主语的身份、特征或状态的。它又叫作主语补足语。表语位于系动词之后，主要由名词、代词、形容词、数词、副词、介词短语、分词（短语）或动名词（短语）等来充当。例如： I am fine . （ fine 是形容词，作表语） He is a boy . （ boy 是名词，作表语） Five plus two is seven . （ seven 是数词，作表语） We are here . （ here 是副词，作表语） He is not at home . （“ at home ”是介词短语，作表语） My hobby is reading . （ reading 是动名词，作表语）,8,二、There be 句型,there be：表示某地有某物，指没有生命的物体有。 例如：There are many books in the schoolbag. have/has: 表示有生命的人或者动物有。 例如：I have many books.,9,单数is 复数are 不可数的 用is,There _ a doll in the toy box.
