be动词后面的动词要加ing吗

2020-06-19 19:33:56文/董玉莹

be动词后不一定加动词ing,也可以加动词ed(过去分词)。be+动词ing表示进行时态,be+动词ed表示被动。例如:1.She was watching TV at this time last night.(was+watching体现过去进行时结构)2.The window was broken by the boy yesterday afternoon.(was+broken体现一般过去时态的被动语态结构)

be动词后面的动词要加ing吗

“Be+现在分词”以组成进行式时态(Continuous Tenses),如:

Tony's maid is washing his new car.

The children are playing in the field.

Samuel was eating when I came in.

We have been living here since 1959.

形式

有不同的be动词,基本上为:

am,is,are,was,were,been,being,be。

被动语态

被动语态的基本结构为be+done(Be动词+动词过去分词)

一般现在时:am/is/are+done

一般过去时:was/were+done

一般将来时:will+be+done

现在进行时:am/is/are+being+done

过去进行时:was/were+being+done

现在完成时:have/has+been+done

过去完成时:had+been+done

一般构句

代词/专有名词+be+普通名词(如我们是亲兄弟)

代词+be+专有名词(如我是爱丽丝)

代词/专有名词+be+物主代词+普通名词(如我是你的亲姐妹)

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:

Don't be silly!

Do be obedient!

Be careful!

Don'tbe a fool!
