英语单句改错题10道＜最好说明错的原因＞．

The doctor tried to persuade him to give (up) smoking but failed.
give in是屈服,give up是放弃.放弃吸烟(即戒烟)
The soldier was (badly) wounded and sent to a hospital at once.＜顺便请翻译出来＞
badly修饰wounded,应该用副词
士兵受得伤不轻,被立刻送往医院.
I didn't go to bed until midnight last night.
go to bed,固定搭配.
When you are in trouble,come to me for help.
When...是“当……就……”的句型,不用and作连接.
After listening to his advice,she found (it) impossible to finish the task on time.
found是及物动词,少了宾语
His poor mother did all she could (to) buy him the expensive toy.
Respecting others (does) everybody good.＜顺便请翻译出来＞
动名词是单数,用does而不用do.
尊重别人对每个人都有好处.
The price of the computer is very (high).
东西贵,价格高,没有说价格本身贵的,又不是在卖价格.
You will surely (succeed) in the exam if you work hard.
如果你努力,你一定会在考试里成功.(怎么反而用了fail,觉得不是语法问题.)
The field,(删除了being) covered with green crops,extends as far as the mountain foot.
种满了绿色庄稼的田地,一直延伸到山脚下.
如果加being的话,就是暗示extends和covered with green crops有必要的联系.但是这里田地有多宽广跟种没种庄稼没关系,所以去掉.

1)The doctor tried to persuade him (to give改giving) in smoking but failed.
persuade sb. doing sth.固定用法
2)The soldier was bad wounded and (been)sent to a hospital at once.＜顺便请翻译出来＞
这个士兵伤得...

1.in改为up give in 屈服，让步 give up 放弃
2.bad改为badly wounded受伤的，形容词，应用副词badly修饰，而不能用形容词bad
“那个战士受伤很严重，被立刻送往了医院”
3.去掉the go to bed 上床睡觉，而不是go to the bed(到床上去，不一定睡觉)
4.将and改为“，” 这两个句子并不应...

The doctor tried to persuade him into giving up smoking but failed.
The soldier was badly wounded and sent to hospital at once.＜顺便请翻译出来＞
士兵受了重伤，立即被送往医院
I didn't go to bed until midnight ...

补充一点（二楼的回答）
His poor mother did all she could buying him the expensive toy.
此句中的buying应该为to buy ( 不定式作目的状语）
