It is a noun clause that can be used as the object of the predicate verb, as well as a preposition and a non-predicate verb (the verb is indefinite). (form, gerund, participle, adjective) object. According to the different conjunctions that guide the object clause, the object clause can be divided into three categories.

and informal style.
For example:

2. An object clause introduced by the connecting pronouns who, whom, whose, what, which and the connecting adverbs when, where, why, how. These linking pronouns and linking adverbs act as components in the object clause. For example:

3. Object clause introduced by if or whether. If and whether in the sentence mean "whether". For example:

He asked me whether (if) I could helphim.
(2) Object clause The word order of
The word order of the object clause should be the word order of the declarative sentence. For example:

(3) The tense of the object clause

For example: I don't think (that) you are right.

2. If the tense of the main clause is past tense, the object clause can only use the corresponding past tense (past tense, past continuous tense, past future tense, past perfect tense) ). For example:
He asked what time it was.
He told me that he was preparing for the sports meet.
He asked if you had written to Peter.
He said that he would go back to the U.S. soon.
3. If the object clause states objective truth, its tense is usually in the present tense.
For example:
Our teacher said that January is the first month of the year.
Scientists have proved that the earthturns around the sun.
4. When the main clause is the predicate When the verb is think, believe, imagine, etc., when the following object clause wants to express a negative meaning, it must be realized through the negative form of the main clause, that is, it negates the verb in the main clause. e.g. I don’t think he will come tomorrow.
(wrong) I think he willnot come tomorrow.
(right) I don't think he will come tomorrow.
Some adjectives can also be followed by Object clause, these adjectives are: sure, certain, glad, pleased, happy, afraid, surprised, satisfied, etc. e.g. I’m sure you can learn English well.
