He has to finish the experiment today. He must be in the lab, ______?A.mustn’t he | B.won’t he | C.doesn’t he | D.isn’t he |

答案
D |
解析
试题分析:考查反意疑问句中尾句部分的助动词用法,must be结构中的中心词应为be,且He must be in the lab相当于I think he is in the lab,故其尾句部分为isn"t he。 考点:考查反意问句 点评;表示猜测的情态动词的反意问句,不应该用情态动词做反意问句,而是根据情态动词后面的动词来定。如情态动词+have done表示推测,如果句中有过去时间,就用过去时的反意问句,如果没有过去时间,就用现在完成时的反意问句。 |
