系动词的词义不完整,要与表语一起才能构成谓语.常用的系动词有be, become, look, taste, turn, smell, go, grow, feel, sound, stay, keep等,今天安颖老师就帮同学们详细分析一下系动词的中考考点.
（1）be 动词
be 动词包括am, is, are. am适用于主语是I 的情形,is适用于主语是第三人称单数的情况,其他情况都用are.

（2）感官动词
感官动词主要有look, sound, smell, taste, feel, touch等,这类动词后不能像be 动词那样接任何成分,只能接形容词做表语.注意感官动词无被动语态.
