E. 动词

(1)动词变化三大黄金法则：主谓一致 ，就近一致， 双动词关系

主谓一致：谓语动词跟着主语发生变化

第三人称单数现象(集体名词做主语)

Our class are playing football now (与人有关的动作)

Our class is a small one (整体)

主谓一致之就近一致(必考)：

There be 句型Either or Neither...nor...

not only...but also.. Not only they but also I am wrong.

时态一致：从句与主句时态一致

He said he had been there for an hour.

He said the sun is bigger than the moon.(自然规律自然现象用一般现在时态)

He said the moon is running around the earth.(错误，应改为一般现在时态)

时态一致之时态变异(必考)：

A——瞬间动词的-ing形式表将来

The plane is taking off in an hour. The old man is dying.(将要死了)

B——条件状语从句：一般现在时表将来

I don't know if he will come tomorrow.

If he comes, I will call you.

I will ring you as soon as I finish my work.

I won’t go out until my homework is done.

典型考题：

---I will go swimming.

---If you go, so will I.

双动词关系：

单句中，若有两个动词(be动词，行为动词，不包括助动词)，他们的关系有四种：

and 连接——动作先后或并列发生，前后形式一致

改为to do——动作未做，准备做 改为doing——动作正在做或已做

改为-ed 形式——后一动作被动发生

特例：* 使、让(make ，let， have)

主动不带to，被动带to

make sb. do /make sb not do/be made to do let sb. do

* The teacher asked the students to stop talking and to listen to her.

* I have my carrepaired.(我请人修理了我的车。车被人修)

I have repaired my car.(我修理了我的车。现在完成时态)

I have him repair my car.(我让他修我的车。Have ab do sth)

(2)动词分类与句型转换

be 动词 am, is, are, was, were

助动词

(1)do, does, did—帮助行为动词做句型转换

(2)have, has, had

will, would, shall, should 帮助表时态

(3)can, may, must, need 帮助表情态

行为动词 like, cry, smile...等等(占99%) 行为动词的所有句型转换均需do家族三兄弟do、does或did帮忙

Be动词、助动词不需任何帮忙

I don't have lunch at home. Neither do you.

(前后主语不一样，Neither do you主谓倒装)

I have been here an hour. So have you.

(前后主语不一样，Neither do you主谓倒装)

---I bought a new book ,Tom.

---So you did.(I 和you 指同一个人，主谓不倒装)
