3、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。
4、目前学到的系动词有 be , feel , look , sound , taste , smell 等动词。
5、例如: This flower is beautiful. I felt very tired. You look worried. It tastes delicious. 3. 表语( Predicative ):表语是用来说明主语的身份、特征或状态的。
6、它又叫作主语补足语。
7、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。
8、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) 二 . 主系表结构的否定形式和一般疑问句形式的构成情况 (一)否定形式: 1. 主语+ be ( is , am , are ) not +表语。
9、 2. 主语+助动词( do/ does )+ not + feel/ smell/ look…… +表语。
10、例如: She is a good girl. → She is not a good girl. You look happy. → You don’t look happy. It smells bad. → It doesn’t smell bad. (二)一般疑问句形式: 1. Be ( Is / Am/ Are )+主语+表语? 2. 助动词( Do/ Does )+主语+动词原形+表语?例如: This girl is in Row One. → Is this girl in Row One? She feels terrible. → Does she feel terrible? We look excited. → Do you look excited? 以上是初中教材中关于主系表结构的重点内容,请同学们一定掌握好。
