系表结构是什么

麻烦举一些例子,还有,系动词

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 等动词。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。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)
  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。
  2. 主语+助动词( do/ does )+ not + feel/ smell/ look…… +表语。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。

  1. Lily is American. (改为一般疑问句)
  2. I am from Sichuan. (改为否定句)

如be,like,feel,taste等感官动词都是系动词,后面跟的形容词、动名词、名词一般都是表语。举个例子,如:I feel tired now.一句中,feel tired 就是系表结构。
