Help! Two questions in junior high English

1c in one's twenties in someone's twenties.

another five years.

3c, a and b are all missing objects, do is a transitive verb and needs an object, and d has a preposed object what, so it is redundant.

4,b。The a tense is wrong and should be used as had madeThe words of c are declarative sentences, while the wondered of the main clause indicates doubt, which should be followed by an interrogative sentence.

Hello classmates!

Pick B. It means that he has already flown to the United States and will not return until two days later. It should be used in the present perfect tense to emphasize that he is gone.

If you choose A, Flew is just a statement of the general past and has no impact on the present, so it is inappropriate.

Hope it helps!!

No, if you choose A, Flew should be followed by an adverbial of past time, but no, it can be seen that it is just a general statement. The present perfect tense is right.

No. Flew is in the past tense and has flown is in the present perfect tense. The difference is that the past tense only denotes the action of the past, and the present perfect tense indicates the effect of the action that took place in the past on the present, and the title means that he flew to the United States, and the effect on the present is that you can't see him.

b Because the person is already in the United States, the present perfect tense is the influence of the present in the past, and the future tense is later used.

b Analysis: Because the present perfect tense indicates the impact of past actions on the present, he is now in the United States, and the effect on the present is that you can't see him, and you have to come back in two days.

No, the present perfect tense means that the action has occurred or ended, and from the title, he has gone to the United States, so choose B

bAffect the present application in the present perfect tense.
