Usage of parenthesis in interrogative sentences

The first sentence is correct. Parentheses like do you think not only play the role of parenthesis, because they sometimes affect the normal word order of sentences and form double interrogative sentences.

The definition of double interrogative sentence should be: "A complex sentence contains two questions, which are not juxtaposed, but a subject and a predicate, but actually only express one question. Such a question is called a double question. "

There are two main types of double interrogative sentences:

First of all, from the general question+question word+clause, (the clause adopts normal word order) as an example:

Can you tell me when he will go abroad for his holiday?

Tell me when he will go abroad for his holiday.

The main clause of this sentence pattern is a question, and the clause is an object clause composed of indirect questions, so it constitutes a double question. The following sentences all belong to this sentence pattern.

1. May I ask you what my teacher will let me do in his office?

Then can I ask your teacher what to do in his office?

Do you know how I can get there in five minutes?

Do you know how I can get there in five minutes?

Do you know whether the army is in urgent need of food at present?

Do you know whether the army is in urgent need of food at present?

Do any of you know where he has gone?

Do any of you know where he went?

Do you know which book is mine?

Do you know that book is mine?

Second, by interrogative words++what do you think+other parts (using normal word order), such as:

What do you think they should do to solve their problems?

This sentence is another form of double question, which is a mixture of general question and special question. When using this sentence pattern, we should pay attention to the following points: ① general interrogative sentences (as you think in this sentence) use interrogative word order; ② Special questions should pay attention to the change of form or word order, that is, special questions should be placed at the beginning of the sentence (such as what in this sentence) and the word order of declarative sentences should be used; Besides think, verbs that can be used in this sentence pattern include say, guess, believe, posture, suggest, imagine, propose and so on. , for example:

1. How old did you say she was? Tell me, how old is she?

2. Guess where we can see him? Where do you think we can meet him?

Who do you think is friendly to him? Who do you think is friendly to him?

What do you think happened to him? What do you think happened to him?

5. How do you imagine him making fun of you?

Can you imagine how he laughed at you?

The meaning of double interrogative sentences is mainly used to ask the other person's opinion, guess or guess.

We can also change the second double interrogative sentence into the following two forms: ① Insert a general interrogative sentence "Do you think" and "Do you believe" after the interrogative word at the beginning of the sentence; ② Add a general question "Do you think" and "Do you believe" after the special question, and change the question mark after the special question into a comma. For example:

1. What do you think they should do to solve their problems?

What do you think they should do to solve their problems?

These two sentence forms can be regarded as variations of double interrogative sentences, because the concept of "what do you think" in the sentence can be ignored, and only an additional question is added in the middle or at the end of the sentence to confirm the facts. "Do you think" in these two formal sentences is generally regarded as parenthesis.

It is worth noting that the first sentence consists of interrogative words+general interrogative sentence "What do you think"+other parts (in normal word order); The second sentence consists of special question+general question "What do you think".
