I had a letter_____(send) in the post office
They had us _____(watch) TV at home
They had us ______(stand)over there
速度，最好有解析

Answer 1

I had a letter (sent/to be sent) in the post office.
They had us (watch)TV at home.
They had us (stand) over there.
解析：
这是一个关于have 用法 此处用到了一组短语 have sth. done 和 have sb. do sth. 其中， have sth. done 中其实省略了 to be ， 所以，答案也可以是to be sent.

Answer 2

记住，have有两种用法，一种是表示“有”，那么后面跟动词不定式，比如I have a book to read.另一种是表示“使，让”，结构是have...do sth./have...done

所以这三道题

1. to send
2. watch
3. stand

Answer 3

不同意楼上的
我记得的是 have 有两种用法
一：have sth done 有被动的意思 比如have my hair cut（cut是被动态） 剪头发（头发是被剪） have my cloth washed
二： have sb/sth do 让某人做某事
所以
答案sent watch stand

Answer 4

sended
watching
stand
