A few fun grammar questions, a grammar question

1 means that only a few of them are ......

2 To mean "up to......"Only use as many as if" and ......As much as "can be used so."

3 the means specifically refers to the people in the back is "nation", but it is indeed a bit awkward.

4 in the town seems to be comfortable with the highest grade in the front.

5 Fish is uncountable when it comes to "fish".

6 Generally refers to all giraffes Not just these or those with long necks.

7 Isn't it common to say what a surprise, such a big surprise?

The correct answer is A, and the analysis is as follows:

1.Question Focus: Usage in the past continuous tense.

2.Common usage of the past continuous tense: Use a longer action or state to show the context in which something happened.

The past continuous is often used in conjunction with the simple past tense, and the simple past tense denotes the action or state in the past continuous tense.

A shorter action or state that occurs in the background.

3.In a word: long movements, carried out in the past; short movements, generally past;

4.Translation of this question: When the teacher and six girls in her class, eight boys are visiting the museum (background, long movement or state), ** happened (short movement);

5.The reasons why option C is wrong, not in line with common sense, are as follows:

Had been visiting is the past perfect continuous tense, which means that the action started before a certain moment in the past, continued until this moment in the past, and will continue to continue, then if the choice c is translated as follows:

At the time of the ** incident, the teacher and six girls in her class, and eight boys were visiting the museum (subtext: at the same time as the ** happened, the teachers and students continued to visit the museum, which was fierce enough!!

A The subject is the teacher 3 single.

This sentence could be changed to the teacher, visiting a museum when the earthquake 6 girls and 8boys of her class

So don't you just choose was, can you understand when I say this?

The answer is a with the accompanying situation, and the subject is the teacher

If there is no comma after class, choose A, if there is, you can't choose A, you can only choose C

a Because this examines subject-verb agreement and tense discrimination, first of all, with when the time adverbial clause can only be used in the general past tense, and then with is the principle of subject-verb agreement, which is determined by the teacher.
