He can't help _____ the heavy box for his classmates,for he is ill.

问题描述:

He can't help _____ the heavy box for his classmates,for he is ill.
A carrying B taking C take D to carry 选哪个,为什么?

D
can't help doing 是禁不住怎么样的意思,但这句的意思是这样的:
他不能帮忙()那个沉重的箱子给他的同学,因为他病了.
可以看出来,这句不是“禁不住”的意思,而不是帮忙做什么,help to do 帮忙做某事,所以选D,意思是:帮他同学提箱子
