Have sth done(选择)
解题思路: 如下
解题过程:
选A正确。
此题考查have的使役动词用法。此题用的结构是have sth done 请别人做某事。
句意是:
--我的腿伤的很重。
--你最好去看医生检查一下。
have sth done, have sb do sth 与 have sb/ sth doing 三种结构的区别:
一、 have sth done

“ have + sth (宾语) + 过去分词(宾语补足语)”意为“让 / 叫 / 使 / 请别人做某事”。宾语 sth 后面用过去分词作宾语补足语,说明 sth 与过去分词表示的动作之间是被动关系。例如:

We had the machine mended just now.

我们刚才请人把机器修好了。

He has had his hair cut.

他(请人给他)理发了。

The patient is going to have his temperature taken.

这个病人准备请 / 叫 / 让人量体温。

二、 have sb do sth

“ have + sb (宾语) + do sth (宾语补足语)”意为“让 / 叫 / 使某人做某事”。此结构中的 have 是使役动词, sb 作宾语,其后的 do sth 是省去 to 的动词不定式作宾语补足语。例如:

The boss often has them work for 14 hours a day.

老板经常要他们一天工作 14 个小时。

I'll have someone repair the bike for you.

我会让人为你修理自行车的。

Don't forget to have Mr Brown come to our party. ( = Don't forget to ask / invite Mr Brown to come to our party. )

别忘了让布朗先生来参加我们的晚会。

三、 have sb / sth doing

“ have +sb / sth (宾语) + 现在分词(宾语补足语)”意为“叫 / 让 / 使某人做某事或让某种情况发生”。宾语 sb/sth 后面用现在分词作宾语补足语,表示宾语与现在分词表示的动作之间为主动关系,且动作正在进行。例如:

Don't have the baby crying! 不要让婴儿啼哭!

Don't have the dog barking much, Lilin. 李林,别让狗狂吠不停。

You'd better have your car running slowly. 你最好把车子开慢点。
最终答案:略
