Introduction: Grammar includes word formation and configuration as well as word formation and sentence formation. The following are the compulsory knowledge points of college English grammar that I have compiled. Welcome to refer to them!

Sound and tense.

? Did you see those people on Xiaosha Island?

? Yes, they have been wiping handkerchiefs for the past half an hour. I want to know why.

A. wave your hand.

Correct answer d

The college entrance examination examines verb tenses. The present perfect continuous tense: it means that the action started from a certain moment in the past and continued until the speech was still in progress or just ended. Adverbials of time guided by for, since, how long, etc. Often appear in sentences. His phone has been ringing for a long time. It has been raining since last Sunday. How long have you been wearing glasses?

What does this question mean? Did you see those people on the island? Yes, I did. They have been waving for the past half hour. I don't know why. ?

The action of waving a handkerchief started half an hour ago, and then it was waved until the time of speaking, so we use the present perfect continuous tense to emphasize the continuity of an action. Let's look at several other tenses:

Option a is waving? In the past continuous tense, it means: ① a certain moment in the past is going on; (2) A certain stage in the past is in progress; Wave? Past tense, an action that happened at a certain time in the past and has been completed, so we know that both tenses A and B are related to the past and have nothing to do with the present, so both answers A and B are wrong.

C. wave your hand. Past perfect tense: an action or state completed at a certain moment in the past or before an action, and then it expresses the past tense. For example, by the end of last year, we had built five new schools. By the end of last year, we had built five schools. First of all, the past time was the end of last year; And the sentence means before the end of last year, so we use the past perfect tense? There are buildings. Now it is even more irrelevant, so this answer is not correct.

What is the adverbial of time in the stem? In the past half hour? Note that this last one doesn't mean. Last one? , but refers to? Just now? In the past half hour? If the words last, last half hour or recent appear in this sentence, we usually choose the present perfect continuous tense because it refers to? Just now? Then it must mean something. From just now to now? . So the answer to this question is D.

2. Nominal clauses

This information may help _ _ _ _ to take over the work.

A.who are those people

Correct answer c

The college entrance examination sites examine noun clauses. As the name implies, they are nouns, which can act as subject, predicative, object and appositive, so the corresponding noun clauses are also divided into subject clauses, predicative clauses, object clauses and appositive clauses. This question examines the object clause after the preposition to.

What does this question mean? This news may be helpful to anyone who will take over the job. ? Who = who? Who is what? So this answer is correct. Let's look at some other answers. Why are they wrong? English grammar must be tested in college entrance examination.

The detailed analysis of option a is those. If you put those in here, it will become a lack of relative pronoun who. If those are selected, then who will take over the work? Who will take the place of this job? It becomes an independent sentence, not a clause, not to mention an object clause, so it is wrong in principle, so how to correct it? It's very simple, as long as you add a relative pronoun who after those, it will become an attributive clause? Who will take over the job? Who will take over the job? That will do.

The b option is the query of who in the noun clause, for example, who will take over the work has not been decided yet. The d option is anyone. The reason for the mistake is also the lack of relative pronoun who.

Compare who with any of those who, which is the former? Those? People? , the latter said? Really? People? . The difference is that those people are a plural concept. Those people? The predicate verb behind it should be plural; And anyone who means anyone, followed by a singular predicate verb.

3. subjunctive mood and modal verbs

? David, we went to Lake Geneva at the weekend.

? This is a very good change. I wish I had gone there.

A. it must be B. It must be C. It could be D. maybe

Correct answer b

Modal verbs are examined in college entrance examination sites.

First of all, there is must in A and B. What does must table guess mean? Are you sure? This tone is very positive,100%; So when it is necessary to guess, it can also indicate different times, for example:

First of all, what does it mean to have to? Current status? He must be a teacher.

Second, do you have to make representations? What's happening now? They must be having a meeting in the office now.

Third, must you have made a statement? What happened in the past? You must have seen him yesterday. Let's see, general? It must be. Is it correct to fill in the questions? Meaning:? David, we went to Lake Geneva at the weekend. ? Oh, that must be a very good change. I wish I had gone there, too. ? There is a positive speculation here; Because it happened last weekend, it means it has happened, so we use B. must have been instead of A.

A detailed analysis of option C is a slight doubt or euphemistic statement of could's views. Maybe? His story may be true, but I find it hard to believe it is true. The story he told may be true, but I hardly believe it.

D option could have been subjunctive, but what might have happened in the past didn't. Is it possible? The accident could have been avoided. The accident could have been avoided. You could have done better, but you didn't try your best. You could have done better, but you didn't try your best.

4. Pronouns

Once a person expresses his thoughts in words to _ _ _ _ _ _, knowledge begins to grow.

A. Another person

Correct answer b

Examining pronouns in college entrance examination sites

When other is used as a pronoun, what does it mean? Another one? 、? Others? , not used alone: the others, others, the others.

1.other ① The other, used with one (all), and one hand/the other hand ② used as the attribute +[pl. ], and the other one? What about the others? I like this book, and I also like other books. I like this book, and I like all the other books.

2. Others' belongs to others. 【pl。 ]? Other people or things? (But not all). For example, some people are carrying water; Others are watering the trees. Some people are carrying water, others are watering trees. (others mean? Other? Not the rest, but? Part)

3.others is the plural form of other, especially? All the other people or things? . I have ten pencils. Two of them are red and the others are blue. I have 10 pencils, two of which are red and the other (8) are blue.

When other is a pronoun, it is often combined with one to form one? Another one? The other guy? 、? Another thing? , refers to two individuals in the same group. One person may like fishing, while another person may like hunting. One person may like fishing, while another person may like hunting. There can't be two people in the world, so that is to say, there is no one. Another one? )

When one person expresses his ideas to another person through language, the understanding of the meaning of the subject begins to increase. Here refers to another person, there is no specific scope to say who and where the other person is, so use one? Another. d option does not have this usage.

5. Non-predicate verbs

Almost every graduate wants to give a keynote speech at the graduation ceremony. For the speaker, _ _ _ _ _ _ is an honor.

A. invited; Invited

Correct answer b

Non-predicate examination of college entrance examination sites

Four points should be considered when analyzing verbs in detail: ① First, judge whether they are predicates or non-predicates; 2 subjects; ③ the subjective and passive relationship between subject and non-predicate verb; (4) Time relationship between non-predicate verbs and predicate verbs For example, being in the sun for too long will be harmful to the skin. Exposure to the sun for too long is harmful to the skin. The girl's education in a good environment is what her parents expect. The girl's education in a good environment is what her parents expect.

Option A of the invitation is a past participle and cannot act as the subject. The c option be invited is not a non-predicate form. Non-predicate is either infinitive, gerund, present participle or past participle. Option D has an incorrect voice and should be passive.
