Question

【题目】The old people _______ lonely at all since we began to visit them once a week．

A. don't feel B. hasn't felt C. haven't felt D. didn't feel

Answer 1

【答案】C

【解析】句意：自从我们开始每星期一次探望那些老人以后，他们就不再感到寂寞了。由since引导的时间状语从句可推测出主句应用现在完成时，表示过去已经开始并持续到现在（也许还会继续下去）的动作或状态，故排除A、D。又因句中主语people为是集体名词，表示复数，排除B，故答案选C。
