When ______ help, one often says “Thank you.” or “It’s kind of you.”
A.offeringB.to offerC.to be offeredD.offered
D

试题分析:句意:当得到帮助时,人们常说“谢谢你”或者“你真好”。offer sb sth提供某人某物,offer sth to sb给某人提供某物,when所引导的状语从句可以省略从句的主语和be ,故选D
点评:由when/If等引导状语从句,如果主从主语一直,并从句中谓语动词有be动词时,可省略if从句中的be动词和主语。状语从句的省略是高中英语必须掌握的知识,并不难,关键在于平时多留心。
