Adverbial clause:

Attributive clause:

Adverbial clause:

When one sentence (clause) is used as an adverbial of another sentence (main sentence), the sentence used as an adverbial is called an adverbial clause. What kind of adverbial is called what kind of adverbial clause. For example, a conditional adverbial clause is a conditional adverbial with sentences.

Classification of adverbial clauses:

(1) adverbial clause of time

All clauses should have leading words, and the words that lead to adverbial clauses of time are when, before, after, until, only, while and so on.

(2) Conditional adverbial clauses

Mainly look at the conditional adverbial clauses guided by if. If means "if". When introducing a conditional adverbial clause, it means that if there is an action of the clause, there will be (not) an action of the main clause. For example:

If it doesn't rain tomorrow, we will go there by bike. If it doesn't rain tomorrow, we will go there by bike.

If I get there earlier, I can see the doctor soon. If I get there earlier, I can see the doctor soon.

3) The usage points of locative adverbial clauses

Where (where) and where(where)eg are commonly used.

Where there is a will, there is a way. Where there is a will, there is a way.

We will go where mother needs us most. We will go where our motherland needs us most.

(4) The usage points of adverbial clauses of reasons

The commonly used leading conjunctions are because, as and since. The difference between the two is: when answering questions, use because; For obvious reasons, such as or because; Often used; As and since clauses are often placed before the main clause, while because clauses are often placed after the main clause. For example.

Why are you going? I went because Tom asked me to. Why are you going? That's because Tom wants me to go.

He was angry not because we were late, but because we made noise.

He was angry not because we were late, but because we made noise.

Since you are not feeling well, you'd better not go to work. Since you are not feeling well, you'd better not go to work.

(5) The usage points of the adverbial clause of purpose

Commonly used leading conjunctions are so that and order that. For example.

Please speak slowly so that we can take complete notes. Please speak slowly so that we can take detailed notes.

I'll write down your address in case I forget it. I'll write down your address in case I forget it.

I sent the letter by airmail so that he could receive it in time. I sent this airmail letter so that he could receive it in time.

Note: the object adverbial clause can be replaced by infinitive verbs. For example.

We work harder than we finish it in a week. In order to finish the work in a week, we worked harder than usual.

Third, the temporal consistency of the subject and clause.

In time adverbial clauses and conditional adverbial clauses, the time consistency of the main clause and clause is generally divided into the following two situations:

1. If the main clause is imperative, or there are modal verbs in the main clause, or the predicate verbs in the main clause are general future tense, then the sentence uses the general present tense to express the general future tense. For example:

Be careful when crossing the road. Be careful when crossing the road.

Please raise your hand if you have any questions. Please raise your hand if you have any questions.

When the red light is on, traffic must stop. When the red light is on, the vehicle must stop.

2. If the predicate verbs in the main sentence all state the past, then the main sentence can use the simple past tense. For example:

She could sing when she was four years old. She could sing when she was four years old.

Object clause:

An object clause is a sentence used as an object component. Its composition is "leading word+subject+predicate+others", and the word order is declarative sentence word order. There are many conjunctions that lead to object clauses, and most of them have practical significance, which are called intentional conjunctions; That can also lead to an object clause, but it has no substantive meaning in itself, which is called an unintentional conjunction.

1 The guided object clause can be used as the object of verbs, adjectives, etc. The common predicate verbs in the main sentence are say, know, hear, see, hope, think, believe, write, tell and so on. After adding adjectives such as fear, worry and affirmation. For verbs, you can also use the object clause guided by them.

I hope he will come back soon. I hope he will come back soon.

2. In that-guided object clauses, conjunctions with no specific meaning can often be omitted in spoken or informal style, and the nature and meaning of the original sentence will not be affected after omission.

3. The tense in the object clause guided by 3.that is usually divided into three situations: if the main clause is the simple present tense or the simple future tense, the object clause can choose the tense according to the specific situation; If the main clause is past tense, the clauses generally use the corresponding past tense; If the clause expresses objective truth, famous sayings, natural phenomena, etc. The tense of a clause is not limited by the main clause.

4. If the main sentence is what I/we think (believe, guess, assume, imagine ...) and the object clause behind it wants to express the negative concept, the negative word not will be transferred to the predicate of the main sentence.

I don't think you are right. I thought you were wrong.

5. When a compound sentence with an object clause becomes an ambiguous question, if the predicate verbs of the main sentence are think, believe, guess, assume, imagine, etc. And the subject is the first person, and the part of additional questions should be decided by clauses; On the contrary, the additional questions are determined by the main sentence.

I don't think he can answer this question, can he? I don't think he can answer this question, can he?

Attributive clause:

Attributive clauses are used as attributes in sentences to modify nouns or pronouns, and the modified nouns, phrases or pronouns are antecedents. Attributive clauses usually appear after antecedents and are guided by relative words (relative pronouns or adverbs).

Relative pronouns are: who who, who, who, who, that, which, etc.

Relative adverbs include: when, where and why.

I like this music, which is why he doesn't like it. I like this kind of music for a reason, but it is just the opposite of me.
