be动词后加“形容词、名词、介词短语、动词不定式、动名词、从句”等作表语。
如:
1、He is happy . (形容词作表语)
2、 She is a student.(名词作表语)
3、He is in a white T-shirt today.(介词短语作表语)
4、His dream is to be a doctor.(不定式短语作表语)
5、 Seeing is beliving .(动名词作表语)
6、 It seems that he is very happy . (从句作表语)
例句对照:
一、【当做主动词时,"be"在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。】例如:
1、The man is a science teacher.
这个男子是一位科学教师。
2、Mary's new dresses are colourful.
玛丽的新衣服色彩鲜艳。
3、I havebeen there before.
我以前去过那里。
4、My motheris in the kitchen now.
我妈妈现在在厨房里。
二、这四个都是陈述句,可以变成疑问句,方法简单,把主语和"be"或助动词对换位置即可:
1、Is the man a science teacher?
2、Are Mary's new dresses colourful?
3、Have I been there before?
4、Is mother in the kitchen now?
三、当"be"要在祈使句中出现时,陈述句可借助助动词"do",否定句必须在前加上助动词"don't",如:
1、Don't be silly!
2、Do be obedient!
3、Be careful!
4、Don'tbe a fool!
四、"Be"有两种缩写法,如下:
1、He's not...../He isn't....
2、You're not...../You aren't...
五、但"am + not"的缩写法只有一个:
I'm not.
六、有人用"ain't", 但这并不是标准英语。
