第23题:[多选题]成绩表score_tb中字段score代表分数,以下()语句返回成绩表中的最低分。【选两项】 A.select max(score) from score_tb B.select top 1 score from score_tb order by score asc C.select min(score) from score_tb D.select top 1 score from score_tb order by score desc 参考答案:BC
第26题:[单选题]Had he worked harder, he ___________ the exams. A.must have got through B.would get through C.would have got through D.could get through 参考答案:C 考查虚拟语气。根据前半句可知该句是省略if的虚拟条件句,表示的情况与过去事实相反,所以主句谓语用would/should/could/might+have+过去分词的形式。相当于:If he had worked harder,he would have got through the exams.故选C。
