系表结构

主系表结构
本结构是由主语+系动词+表语组成，主要用以说明主
语的特征，类属，状态，身份等。

系表结构有两部分构成：连系动词和表语。

下面分别解释一下：
一连系动词：
连系动词分为三类：be 动词，感官动词，趋势动词。

1) Be 动词：am, is, are, was, were
2) 感官动词：sound, look, taste, feel, smell
3) 趋势动词：appear, become, grow, get, turn, seem, remain
二表语：
下列成分都可以做表语：名词，形容词，副词，动词不定式，动名词，现在分词，过去分词，表语从句．
使用举例(注意：连系动词不能够单独作谓语，他们必须和表语一起工作构成谓语):
1) 名词:
False：I am.
Right：I am a student.
2) 形容词：
False：He became.
Right：He became strong.
3) 副词：
False：She remained.
Right：She remained there.
4) 现在分词：
False：The story seemed.
Right: The story seemed interesting.
5) 过去分词：
False：The windows seemed.
Right: The windows seemed broken.
6) 动名词：
False：His job is teach English.
Right: His job is teaching English.
7) 动词不定式：
False：Her plan is become the winner in the game.
Right: Her plan is to become the winner in the game.
6）和7）的区别：
6）中动名词表示某人经常干某事：她从星期一到星期五天天教英语；
7）中动词不定式表示某人将要干某事：她的计划是将要成为比赛的胜者。

系动词有:
1.表示特征和存在状态的be, seem, feel, appear, look, smell, taste, sound;
2.表示状态延续的remain, stay, keep, continue, stand;
3.表示状态变化的become, get, turn, go, run, fall, come, grow;
