When help, you should say “thank you.” or “It is kind of you”.
A. offering
B. offered
C. To be offered
D. to offer

A. offering(答案→)B. offeredC. To be offeredD. to offer解析：考查状语从句的省略：句意：当被提供帮助的时候，你应该说“thank you.”或“It is kind of you”。这是省略句，完整的句子是：When you are offered help，当主从句的主语一致的时候，可以省略从句的主语和be动词，选B。
