1. He usually goes to school by his father’s car.

by加上名詞表示一種交通方式，中間什么都不加，如by car, by bus, by plane等；如果名詞前有其他的詞修飾，則應除by以外的其他介詞，此處把by改為in.

2. Please wait me at the school gate.

wait為不及物動詞，需加介詞for后才能再跟名詞或代詞做賓語。

3. He has been married with Betty for more than twenty years.

marry不跟 with連用，應把with改為to。

4. I finished the work on time under the help of him.

“在…的幫助下”用with而不用under。

情態(tài)動詞

1. He can be at home now because the light in his room is still on.

表特別有把握的肯定判斷時用must，表特別有把握的否定判斷時用can, can表判斷時只用在否定句中。因此把can 改為must。

2. He need come here before the meeting begins.

作情態(tài)動詞時need用在否定，疑問和條件句中，不能用于肯定句中，而作實意動詞時則可以。所以應改為：He needs to come here before the meeting begins.

3. He used to get up very early in the morning, and now he is still doing so.

used to 用來表示過去常常做某事而現(xiàn)在不了，所以應把后半句改為：but now he is not doing so.

4. I needn’t come yesterday because all the work had been finished.

由于情態(tài)動詞本身不體現(xiàn)時態(tài)，所以在談論過去的事情時在情態(tài)動詞后加 have done，因此在 needn’t 后加have。

5. You hadn’t better stay up too late because you have to get up early tomorrow.

had better 的否定在 better 后面加not.

動詞的時態(tài)

英語的常用時態(tài)有十六種，一般根據(jù)上下文和時間狀語來確定時態(tài)。

1. I will tell her about that when she will come tomorrow.

主句為將來時，其時間、條件、方式和讓步狀語從句中用一般現(xiàn)在時。因此將will come改為comes。

2. The meeting is about to begin in ten minutes.

be about to 一般不與具體的時間狀語連用。因此把 in ten minutes 去掉。

3. The boy opened his eyes for a moment, looking at the captain and then died.

此處look并非伴隨狀語，而是三個并列的謂語動詞，因此把looking 改為looked。

4. I have bought this bike for ten years and I am still using it now.

當句中有for加一段時間作狀語時，謂語動詞必須為延續(xù)性動詞，此處把bought改為kept。

5. I haven’t learnt any English before I came here.

我來這兒已經(jīng)是過去的動作，在此之前發(fā)生的事應該用過去完成時。因此應把haven’t改為hadn’t
