Question

【题目】—I took care of my grandfather in hospital.

—Is that ________ you had a few days off?

A.whatB.whenC.whyD.where

Answer 1

【答案】C

【解析】

句意：——我在医院照顾我的祖父。——那就是为什么你这几天请假的原因？

考查表语从句。what什么；when什么时间；why为什么；where哪儿。根据“I took care of my grandfather in hospital”可知此处在表达“had a few days off”请几天假的原因，用why来引导表语从句。故选C。
