The collocation of be verb and subject?

English be verb is a verb with complicated usage. There are two reasons for this complexity:

1. Besides the original be, different personal pronouns, singular nouns and plural nouns have various forms and abbreviations. To sum up, there are seven forms: be, am, is, are, was, was, bee and being. Their collocation relations with personal pronouns and noun singular and plural are as follows:

The present tense I am, you are, he/she/it/yes, we/you/they are; Is is used for singular nouns and uncountable nouns, and for plural nouns.

Abbreviations I am, you are, he is, we are, you are, and they are.

Negative abbreviation I'm not, not, not.

I was, you were, he/she/it/was, we/you/they were; Singular nouns and uncountable nouns are used as was, and plural nouns are used as was.

The negative abbreviation is' t, were t.

Past participle been

Present participle being

2. In a sentence, be has two main functions: first, as a connecting verb, it can act as a predicate verb; Secondly, as an auxiliary verb, it forms various tenses and passive voices together with the predicate verb.

Let's explain it briefly.

First of all, the be verb is a copulative verb.

"1, connecting verb+predicate" structure

When the be verb is used as a copula, it mainly forms the structure of "copula+predicate" and acts as a predicate in the sentence. Predicates can be nouns, adjectives, adverbs, prepositional phrases, etc. For example:

This man is a science teacher.

Mary's new skirt is brightly colored.

Mom is in the kitchen now.

I have been there before.

They will be here tomorrow 10:00.

That can't be true.

You are not very polite.

Your brother is very annoying tonight

2. The general interrogative sentence of the 2.be verb is moved before the subject or at the beginning of the sentence.

Is this man a science teacher? Yes, he is. No, he isn't.

Is Mary's new skirt brightly colored? Yes, they are. No, they aren't.

Was mom in the kitchen then? Yes, she is. No, she isn't.

Were you at home the day before yesterday? Yes, I am. /No, I'm not.

Was she late this morning? Yes, she is. No, she isn't.

3.be verbs are used in special interrogative sentences.

In special interrogative sentences, be verbs still move to the front of the subject, but special interrogative sentences start with special interrogative words, so be verbs can only be said to move to the front of the subject or behind the special interrogative words. For example:

Whose bike is broken? Xiaoming's bike is.

Who is singing in the room? Mr. Zhang is.

Where are you from? I come from Wuhu.

Which class are you in? We are in Class Two.

How old is Tom? He is ten years old.

4. The negative sentence of the 4.be verb

When the verb be is used as the predicate, its negative form is to add not after be, which can be abbreviated. For example:

Today is not sunny.

Tom and his friends are not in the park.

You were less than nine years old when I went to college.

When he was a student, he was often late for class.

I was not here yesterday.

My parents were not at home last Sunday.

5.be verb imperative sentence

The imperative sentence of be verb has two forms: affirmative sentence and negative sentence. The masculine form begins with a be verb, while the feminine form or stressed sentence form should be added with don't or Do. For example:

Be careful!

Be a good boy!

Don't be silly!

Don't be silly!

Be sure to listen!

Be careful.

Second, be an auxiliary verb.

The auxiliary verb be has two basic uses, one is to form various tenses with the predicate verb, and the other is to form the passive voice.

1 and "be+ present participle group" are various progressive tenses. For example:

Tony's maid is cleaning his new car.

The children are playing in the field.

Samuel was eating when I came in.

We have lived here since 1959.

At this time the next day, they will be sitting in the cinema.

Third, matters needing attention

In English sentences, several auxiliary verbs are often used together to express the need of tense or passive voice. In other words, the auxiliary verb be will be used with other auxiliary verbs. At this time, the general interrogative sentences and negative sentences of the whole sentence do not have to be changed, but are mainly changed by the first auxiliary verb. In other words, which auxiliary verb appears first is the main verb to be changed. For example:

All the wonderful birds can be found in our bird park.

[Question] Can we find all the wonderful birds in our bird park? (Move the first tank)

We can't find all the wonderful birds in our bird park (add not after the first can)

I have been there before. (two auxiliary verbs: have, be)

Have you been there before?

I have never been there before.

I will meet my boss at six tomorrow night. (two auxiliary verbs: shall, be)

[Question] Will you have dinner with me at six tomorrow night?

I won't meet my boss at six tomorrow night. Fourthly, the meaningless auxiliary verb be is used as a predicate verb to assist the main verb in the sentence. Usage is as follows:

1.be+doing: it constitutes the progressive tense, which has two kinds of progressive tenses: present and past. For example:

The girls are reading and copying new words.

Young Tom is always asking questions and trying new ideas.

Be+going to do means "going to or going to do something". Be has two forms: present and past. For example:

We are going to plant trees in the park.

I don't know whether she will come here.

Be+to do means "do something as planned". For example:

The new store won't open until next Monday. One night, an angel came.

Mary told her that she would give birth to this special boy.

Verbs (short for verb) are

There be: there be+ subject part+adverbial part, which means "there is something somewhere". Be is often used in present tense, past tense and future tense. For example:

Oh, cool! And there are many things to see. There is even a deer garden in Sanya.

There are about 80 pyramids in Egypt.

Will there be a football match in your school next week?

Sixth, the real meaning is

Be can be regarded as a notional verb because it has practical significance, such as "becoming; Do; Happen; Hold; Stay; Arrival "and so on. His great dream is to be an animal doctor in his twenties. Kate's birthday party.

Will arrive at 6: 30 this evening. Jim has stayed in China.

More than two years, but he hasn't been to Yichang.
