大家好,小跳来为大家解答以上的问题。系表结构英语,系表结构这个很多人还不知道,现在让我们一起来看看吧!

1、1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。

2、 2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。

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。

11、   请大家按句子后面括号内的要求改写句子:   1. Lily is American. (改为一般疑问句)   2. I am from Sichuan. (改为否定句)   3. He looks puzzled. (改为一般疑问句)   4. They feel very excited. (改为否定句)   5. I am not feeling well. (改为肯定句)   6. The news sounds very bad. (改为一般疑问句)   7. We are all here. (改为一般疑问句)   8. The food tastes delicious. (改为一般疑问句)   9. Its name is Mimi. (改为否定句)   10. I feel well. (改为否定句)   Key:   1. Is Lily American?   2. I am not from Sichuan.   3. Does he look puzzled?   4. They don’t feel excited.   5. I am feeling well.   6. Does the news sound very bad?   7. Are you all here?   8. Does the food taste delicious?   9. Its name is not Mimi.   10. I don’t feel well。
