Question

【题目】Mr Jiang isn’t as busy as before because there no home robot to help him．

A. used to beB. may beC. used to haveD. may have

Answer 1

【答案】A

【解析】

句意：江先生不如以前忙，因为过去没有家用机器人来帮助他。used to be过去是， may be可能是， used to have过去有，may have可能有。There be句型，表示存在，意为“有”。根据Mr Jiang isn’t as busy as before可知此处指的是过去，故用used to be。故选A。
