Ask a few English questions to answer and analyze and involve relevant grammar, be detailed, if you

Depending on the context, one of them did not recognize the other, so the first person would say, "It's you!" I didn't recognize you just now (because the other person had cut his hair and wore new glasses). Because it is now recognized, it is in the past tense.

It is possible to use the method of elimination. Because the ** bell is no longer ringing, C (ringing often) and D (ringing in the past to the present) are excluded, A must have a past time point in time when it is completed in the past, and B means smoothly: ** is ringing just now, and it is in the past continuous tense.

According to the sentence: we were all surprised when he indicated that he would leave the office immediately. Seeing that soon is used in the future tense, the main clause is in the past tense so the clause is also in the past tense, so it is in the past future tense

According to the meaning of the sentence, a reporter from vanity fair has been playing for a day and is still playing (now), so it makes sense to use the present perfect continuous tense (an action has continued from the past to the present and is still in progress) When the present completion continuous and the present perfect tense appear in the options at the same time, it generally makes sense, but it is better to give priority to the former, oh haha, but it still has to be based on the sentence meaning

41 selections from last month and continuity time for three days. It can be known that the verb is used in the form of state

47 out of Awas waiting According to the question, I was waiting for my uncle at the station when I was supposed to go to the movies.

It could be this.

Explain that he has been waiting for his uncle at the station at that time.

1. d for three days indicates that it is continuous and cannot be used. Went last month means that it is in the past, so a or b in the present perfect tense is not selected

3. A is in the context of the past continuous tense, "I was waiting for my uncle at the station".

Even though we hadn't seen each other in 30 years, I recognized him as soon as I saw him.

i recognized him the moment i saw him, though we hadn't seen each other for thirty years.

I recognized him when as soon as I saw him, you have doubts, it makes sense. The best way to use it is to leave this blank blank unfilled, because it is redundant to fill in any of the options!

This is the test point of the definite clause, the antecedent is the minute the moment that expresses "time", and the leading word of the clause (relative adverb when) is usually omitted.

If you have to choose one of the four options, only A is possible.

This question examines the choice of relative words in the definite clause, so we should be clear about 1The relative word of the definite clause replaces the noun that precedes it, which is called the antecedent 2Relative words act as sentence components of clauses in definite clauses.

3.Relative words are divided into relative pronouns and relative adverbs, usually, relative words are used as subjects, objects, predicates, and definite clauses in definite clauses, and relative pronouns are used, such as that, which, who, whom that, whose, and relative adverbs are used as adverbs, such as why, when, where, how

Knowing these three rules, we will find that the choice of relative words is 1Related to antecedents, 2It has to do with the sentence component that the relative word acts as a clause.

A common mistake students make is that when the antecedent is time and place, the relative word may be that, which, or when, where, and the key depends on the sentence component that is used in the definite clause.

Let's look at this question, the antecedent is the minute, which refers to time, so the key is to look at the sentence component of the minute in the definite clause. The clause is i saw him (at the minute), and I saw him at that moment. So it acts as a temporal adverbial.

Therefore, the relative adverb should be used, when.

The answer is C, this is a phrase, the minute (that) has when... The meaning can be seen as when or while, and there is also a··· Just... It's actually the same as when... It's almost the same to use.,It's the usage of as soon as.,Why can't other options?,As long as there is no minute,Other options can be selected.,They all have when··· Usage.

I think b should be chosen, and as means that the action of the main clause and the action of the subordinate clause occur at the same time. This means that I recognized him as soon as I saw him. Seeing and recognizing are simultaneous.

First of all, this blank can actually be left unfilled, in that case, the minute is equivalent to a conjunction, leading the time adverbial clause, which means "one." Only. Equivalent to the second, the moment.

Secondly, there is something to be filled in here, which tends to be a definite clause, in which case you can fill in that or at which.

although we hadn't met for 30 years, i recognize him the minute __that__i saw him.

a. when b. as c. that d while

the minute moment instance that is equivalent to the time adverbial clause when leading clause; eg.

the minute （that）i saw her, i realized something was wrong.

as soon as i saw her, i realized something was wrong.

when i saw her, i realized something was wrong.

Answer a, definite clause, sentence can be seen as i saw him at the minuteWhen is equivalent to at which

1.It's easy to understand, because whether it's this part of the book or another part, the nouns referred to are books, plural.

2.The first thing to understand is that one side tries to attack the other side's opinions, where one side tries to refute the other's point of view. Where refers to this, this one aspect.

3.Semantically, he asked me if I had donated to Project Hope. There is no doubt about the choice of whether, whether it means or not.

Most of books refers to parts, so with plural, the rest also refers to parts.

Non-restrictive definite clauses, no components.

Usually whether is used in conjunction with or not, and according to the meaning of the sentence "What did the squad leader tell you just now", I learned that "he asked me if I had donated to Project Hope".

It is recommended that you buy a grammar book and read it, which has detailed explanations.
