He doesn t think i can sing in English instead of an anti meaning interrogative sentence, plus an in

he doesn't think i can sing in english, does he?

The general rule of anti-meaning interrogative sentences is that when the main sentence is an affirmative sentence, the rhetorical question is negative; When the main clause is a negative sentence, the rhetorical question is affirmative. The main sentence of this sentence is negative, and the rhetorical question is negative.

In general, what type of auxiliary verb is used in the main clause, and the rhetorical question is what type of auxiliary verb to use. As the main sentence of this sentence is used"do" is also used as an auxiliary verb when asking rhetorical questions"do"。

If the main sentence is used"be"(is a verb), rhetorical questions should also be used"be"：

you are a student of this school, aren't you?

Other analogy: they can't finish the work by this evening, can they?

she hasn't been to beijing, has she?..

Answer: I think he can't do this,【can he】?

I don't think he can do this, can he?

The antonym question sentence is preceded by no and then yes, and the front is used before and after no, and the negation can is used in front't, so use affirmation later.

I should eat with chopsticks.

This is a sentence containing the modal verb liquid family should, declarative sentence, to change to a general troublesome interrogative sentence, as long as the modal verb should is advanced to the subject i, if the subject is in the first person, to change to the second person, here to change the subject i to the second person you, and then change the full stop at the end to a question mark, as follows:

should you eat with chopsticks?

Should you eat with chopsticks?

The general question sentence is that you can only use yes or no, and you can use yes, i should. in this Zen family

Satisfied, thank you!

This sentence uses the modal emotion to talk about the celebration, and it should be changed to a general grinding question and rotten grip sentence, and put should at the beginning of the sentence, that is, should I eat with chopsticks?

Answers for you.

Let's take it one sentence at a time.

One, when using i think i don't think, the antonym interrogative part is determined by the willingness or absence of the clause. i don't think is actually expressing the negation of the clause, so the antisense question part needs to be affirmed. Therefore, your first sentence is right.

Such as: i don't think that you can do it, can you?(Don't do i?.))

we don't believe that the news is true, is it?(No need to do we?.))

Second, when someone else thinks, we are asking the part of the main clause and asking whether the subject thinks or does so, so according to the willingness of the main clause, you didn't in the second sentence'The he in t he does not refer to, but the subject he.

For example: they all think that english is very important, don't they?(No need.)'t it?)

he didn't think that the news was true, did he?

The answer is; has

In the anti-meaning interrogative sentence, when the statement part is the object clause, the subject of the main clause is the first person, and the predicate is think, suppose, believe, suspect, imagine, etc., the question part corresponds to the object clause to form an anti-meaning interrogative sentence. Such as:

ithinkheis

right,isn't

he?If the subject is not the first cherry blossom blind person, the interrogative part corresponds to the main clause to form an anti-interrogative sentence. Such as:

hethought

theywere

wrong,didn't

he?When negating the preposition, e.g. i

don'tthinkheis

right,is

he?The statement part of the ridge is empty.

ithinkheis

notright

Therefore, the question part is buried with an affirmative structure, which is. ishe?

In this question, first of all, the main clause is the first person, and the predicate verb is think, so the question part corresponds to the clause; The clause is in the present perfect tense, and the question part should be asked with the auxiliary verb has in the present perfect tense; And because the negation precedent is equivalent to the statement part of the negative, so the question part is yes. So, the answer is: has

he?Hope it helps!
