[解析]
Dear Steve,
How's everything going? I am writing this letter to sincerely apologize for you for not being able to return your MP4 on time.
To begin with, thanks again for lending me your MP4, that indeed helps me a lot with my listening. But unfortunately, when I used it as usually yesterday, it broke off suddenly for no reason. Then I read the instructions carefully, and couldn't find any reason. Then I took it to a shop to have it repair and the worker there said I could get it back on Tuesday. I'm sure I can return it back by then. If not,I will buy ∧new one for you.
Once again, I'm truly sorry for any inconvenience that I've caused. Looking forward to hear from you soon!
Yours,
Rachel
详解:
1. for改成to.考查固定短语.apologize to sb for sth是固定短语"因为某事向某人道歉",所以用介词to.
2. that改成which.考查定语从句.本句是非限制性定语从句,关系代词在从句中做主语,所以用which引导.
3. helps改成helped.考查时态.本文的叙述是过去时,所以用helped.
4. usually改成usual.考查固定短语.as usual是固定短语"和平常一样".
5. off改成down.考查固定短语.break down是固定短语"坏了".
6. and改成but.考查连词.我仔细地读了说明,但是没有发现原因.所以用but.
7. repair改成repaired.考查非谓语.it与动词repair之间是被动关系,所以用过去分词在句中做补语.
8.去掉back.考查动词.return是及物动词"归还",所以back是多余的.
9. 加a.考查冠词.买了一个新的,这里是泛指,所以用不定冠词a.
10. hear 改成hearing.考查动名词.look forward to是固定短语"盼望着",介词to后跟动名词.
