have been 和 has been的区别

1. have been 和 has been的区别

have been 和 has been的区别,主要看主语，主语是三单用has，不是就用have。

have been的主语是除了第三人称单数以外的人称，如
I have been to Beijing many years before.
They have been to Shanghai for a long time.

has been 的主语是第三人称单数，如
He has been to Harbin before.
Shs has been to Hainan these days.

have/has + pp 是主动语态
have/has + been + pp 是被动语态

2. 时态的十个公式，如下格式：have/has+been+pp。had+been+pp。would+be+pp..越多越好，谢谢

1. 一般现在时  He cleans the blackboard. The blackboard is cleaned by him.
2．一般过去时 He cleaned the blackboard. The blackboard was cleaned by him.
3．一般将来时 He will clean the blackboard. The blackboard will be cleaned by him.
4．现在进行时 
He is cleaning the blackboard. The blackboard is being cleaned by him.
5．过去进行时 He was cleaning the blackboard. The blackboard was being cleaned by him.
6．将来进行时 He will be cleaning the blackboard. The blackboard will be being cleaned by him.
7．现在完成时 He has cleaned the blackboard. The blackboard has been cleaned by him.
8．过去完成时 He had cleaned the blackboard. The blackboard had been cleaned by him.
9．将来完成时 He will have cleaned the blackboard. The blackboard will have been cleaned by him.
10．现在完成进行时 He has been cleaning the blackboard. The blackboard has cleaned by him.(完成进行时没有被动语态，该意思用相应的完成时语态或进行时语态表示。可参看薄冰语法）（The blackboard is being cleaned by him.)

11．过去完成进行时 He had been cleaning the blackboard. The blackboard had cleaned by him.（The blackboard was being cleaned by him.）

12．将来完成进行时He will have been cleaning  the blackboard. The blackboard will have been cleaned by him.（The blackboard will be being cleaned by him.）

3. 现在完成式的句子当中，have-has+pp两个是当一个动词来看？还是pp动词，have-has助动词？

虚拟语气中会这样用。
have has +pp     have 、has 、had   它们都只是助动词 have has 使后面的动词变成了现在完成式
现在完成时：就是说这个动作已经发生完了，但对现在还有影响

had 是后面的动词变成了过去完成时。我丢了钥匙（我可能进不去屋了）
过去完成时：动作发生在过去的过去。（昨天早上我进办公室前他已经打扫完了卫生）

在虚拟语气中：
与过去事实相反的假设时：条件句 过去完成时
主句  过去将来完成时
If I had used that word to describe you,it would have been better.
If I had eaten the rice,I would have gone to school with you.

4. have+P.P和have been+p.p有什么区别

应该选B啊，表被动。A是将要被替换，和后面时态不一致所以不选。C和D是主动，不应该选。这个句式应该用被动，意思是所有的坏窗户已经被换了，所以屋里更加的暖和。

5. 求is/am/are+being +pp 和 have/has+being +pp的分别

前者是现在进行时的被动语态
后者是现在完成进行时的被动语态

希望可以帮到你

6. have/has+v.(p.p)是什么意思

v.(p.p) 指过去分词have / has + 过去分词  构成现在完成时

I have been to Japan twice. 我去过日本两次。

7. was were＋动词ing与be＋动词过去式区别，had＋pp.与have\has＋pp.的区别

was/were＋v-ing是过去进行时，描述过去正在进行的事情
be＋pp是被动语态的形式，表示动作被做

had＋pp.与 have\has＋pp都是完成时态，都表示动作已经完成，只是前者是在另一动作前就已经完成，而后者强调此时已经完成，并对于现在产生影响

8. **pp++ 和**++pp和*++*pp的区别
