Fill in the blank in English, when to fill in that and when to fill in what

Distinguish between pronouns and interrogative words.

It depends on what kind of question you fill in.

There are two ways to keep the finger file round:

1.Dual-function method: what is equal to the "antecedent + relative pronoun" in the definite clause, for example:

they reached (a place which/that )is called nanjing.(They came to a place called Nanking.) ）

In the sentence, which is called nanjing is a definite clause, which that is a relative pronoun, modifying the antecedent A place

Can be converted to: they reached (what) is called nanjing

They reached ( is called nanjingThink of it this way: the object needs to be followed by reach; The subject needs to be preceded by is, so the only word on this space must have a dual function.

2.Three-point comparative method:

that: (1) conjunctive sentence, (2) does not act as a component in the clause, and (3) has no Chinese meaning.

For example: that he is a greatest scientist is known to us all(He is known to be a great scientist.) )

what() connects the sentence (2) as a component in the clause (3) and has a Chinese meaning.

For example: what he said is right(He was right).

What is connected to the leading clause, as the object of said, means that "what is said is stupid".

what

1.Introductory noun clause: i don't understand what he is talking about.

In this sentence, what is an object in a noun clause).

it is difficult to decide what should be done first.

In this sentence, what is the subject in the noun clause).

2.Introductory exclamation: i can't believe what a beautiful girl she is.

thatthat is the subject, predicate or object in the definite clause, and can be omitted when it is used as an object.

Cases in which that must be used:

Antecedents: There are people and things.

Antecedents have adjectives superlative.

Antecedents are indefinite pronouns.

Antecedents have indefinite pronoun modifications.

Questions that begin with who, which.

Antecedents are modified by words such as the very, the same, and the last.

Antecedent words are ordered to be numerals, and when the numerals are modified.

When a relative word is used as a predicate in a definite clause.

Cases in which that cannot be used:

Preposition + relative.

Non-restrictive definite clauses.

For example: is this the book that you borrowed in the library?

Is this the book you borrowed at the library?

who that break the window should be punished．

Whoever breaks a window will be punished

all that is needed is a supply of oil.

All that is required is the issue of oil supply.

finally,the thief handed everything that he had stolen to the police.

The thief eventually handed over all the stolen items to the police.

That and what guide the way to distinguish noun clauses.

he did not comment on what i said.When I say it, I mean what I say, which has a practical meaning, something like that. And that does not contain the meaning of what is spoken.

If there is that, then the object of said is missing, and the structure is incomplete.

Therefore, we choose what, just like what to say do and so on.

that

Both with what can lead to the subject clause, that

It is not a sentence component in a clause, but it cannot be omitted.

What can be used as a subject in a clause

Objects, predicates, etc., cannot be omitted. Such as:

What he said at the meeting was very important.

What surprised us is that he did it alone.

Make. (Subject).

That he did it alone surprised us.

That is used to guide the subject clause, and it is not used as an ingredient in the sentence) This question what is the object of said.

Hello, remember two methods:

1.Dual-function method: what is equal to the "antecedent + relative pronoun" in the definite clause, for example:

they reached (a place which/that )is called nanjing.(They came to a place called Nanking.) ）

In the sentence, which is called nanjing is a definite clause, which that is a relative pronoun, modifying the antecedent A place

Can be converted to: they reached (what) is called nanjing

They reached ( is called nanjingThink of it this way: the object needs to be followed by reach; The subject needs to be preceded by is, so the word on this space must have a double function.

2.Three-point comparative method:

that: (1) conjunctive sentence, (2) does not act as a component in the clause, and (3) has no Chinese meaning.

For example: that he is a greatest scientist is known to us all(He is known to be a great scientist.) )

what() connects the sentence (2) as a component in the clause (3) and has a Chinese meaning.

For example: what he said is right(He was right).

What concatenate the leading clause, as the object of said, which means "what has been said".

That can be used as an object, or it can be followed by a sentence.

What is usually a question, sometimes placed in a clause as an object (followed by the word order of a declarative sentence).

There are too many of these situations to summarize at all.
