关于两句英语的语法问题
Booking the hotel and the flight tickets is difficult.是不是这种情况都是就近
They have been to GW,haven't they不是说如果是经历的话就用didn't they吗
答
Booking the hotel and the flight ticket is difficult (不是就近,是表示一种概念作状语,谓语动单数)
They have been to GW,haven't they ( 反意思疑问句,主动词否定+主语 用法 ,所使用助动词与前面句子保持一致)haven't they?)但是我记得好像如果have后跟的是经历的话,后面是用do接的句子使用现在完成时态 ,助动词 has /have +动词过去分词,表示一种时态,后面反意疑问句,必须助动词+否定+主语(1)前面是肯定句,反意疑问句为否定 :反意疑问 助动词+NOT +主语(2)前面是否定句,反意疑问句为肯定 :反意疑问 助动词 +主语
