Question

When _____ help,one often says“Thank you.”or“It's kind of you.”

When _____ help,one often says“Thank you.”or“It's kind of you.” A.offering B.to offer C.to be offered D.offered

Answer 1

选D 当状语从句的主语和主句主语一致时，可以把从句中的主语省略。

这句话完整的应该是When one is offered help,one often says"Thank you "or "It's kind of you." 道谢的人肯定是被给予帮助所以用被动语态。

C项虽然也是被动，但不定式表示的是”将来“，这里是描述的一般情况，故用一般现在时的被动，表示经常发生的情况。

类似用法还可以说:

She did an excellent job when given a chance.

She cried her heart out when shown the letter of her son.

one 和offer 的关系是被动，排除A 和B ， C 的动作还没发生，故选D
