Question

【题目】When _______help, one often says ‘Thank you. ‘or 61t's kind of you.'

A offering

B. to offer

C. be offered

D. offered

Answer 1

【答案】D

【解析】句意：当一个人得到帮助时，往往会说“谢谢”或“你真好”。when offered help是省略了主语与be动词的时间状语从句。在when，while，if等引导的状语从句中，当主句主语与从句主语一致且从句谓语动词含be动词时，从句主语与be动词可省略。此处主语one是动词offer的承受者，从句应用被动语态，完整句式为when one is offered help，省略后即为“when offered help”，故选D。
