Question

a) Should have
shouldn I have
b) wouldn't have
d) would have​

Answer 1

Explanation:

a) Should have

Should have is used for the subject to be done something, it's the most common word for using in english grammar.

for example: I should have gone to school

You should have lunch before you go out.

Here, in this 2nd sentence, it refers to the subject which orders the object to do something, had is sometimes used as the word 'eat' or most of the time a helping verb.

b) Shouldn't have

Shouldn't have is used for the subject to be not done in past, it's exactly opposite sentence to the word should have which is affirmative ( positive)

sentence. It is used for many ways.

For example: I shouldn't have go to school

: You shouldn't have lunch before you go out.

The same examples with not added given to the b) to understand the differences. In the same 2nd sentences. The subject orders object to not do something.

some other examples are: it's raining, we shouldn't have cotton shirts with us

We shouldn't have seen this movie as it is scary.

c) wouldn't have

Wouldn't have is used for an subject to not take decision of his/herself or for others. And very common in grammar. This is a negative word just like shouldn't have but way more different.

for example: I wouldn't have go to school when you said it was summer vacation.

: You wouldn't have lunch before you go out.

But in the second sentence, the sentence may feel too complex but helpful when understood clearly. Here, the subject offers object that it's decision is something like improper etc.

d) would have

Would have is a word that is used for a subject to take decisions him/herself so that it may be helpful. And very common in grammar. But affirmative just like Should have.

for example: I would have gone to school

: You would have lunch before you go out.

Here, at the 2nd sentence, again, you see that the subject says the object that it's decision will be done. And very different from the word wouldn't. This is a little complex but simple by the way when you understood clearly.

the other examples are

I would have a raincoat if there was a rain

I would have finished the homework if you let me to write.
