几道英语单选题,谁能给我解释一下选项的原因~
I couldn't help her _A___the heavy bag for Lucy,as I was too tired at that time.
A carrying B carry C with carrying D being carried(为什么不选B)
The girl is lucky enough to have many people __A_ her with the work.
A help B to help C helped D helping(为什么不选B)
I'll get my secretary _B__the letter.
A copy B to copy C copies D copied(为什么不选A)
Whose turn _A__ on duty today?
A it will be B is it to be C is D will be
If you _D__ keep out of trouble,you must study harder.
A want B will be C are going to D are to(为什么不选C)
The light A__ went out ,so she had to go to bed.
A went out B has gone out C turned off D had gone
打错了第四题选B

【1】B.可能是答案错了吧,如果用doing,那应该是can‘t help doing sth“情不自禁做某事”不应该有her.相信自己!
【2】让某人做某事的几种说法：
let sb do sth
= have sb do sth
= get sb to do sth
【3】同【2】
【4】可以先把它化成陈述句：
It will be one’s turn on duty today
对one’s turn提问,显然选A
【5】考察be going to do 和be to do 区别
be going to do表示打算或计划要做某事
be to do表示安排要做某事,另外还有一种“想要……”的意思,如：
If trees are to survive,they should be watered in time.
【6】go out “灯熄灭；耗尽”不及物,无被动语态.
以上是我个人愚见,希望对你有用
