26.____________ before we leave,the day after tomorrow,we should have a wonderful dinner party. A.Had they arrived B.Would they arrive C.Were they arriving D.Were they to arrive 考的语法是什么?
D 这是考的过去时的虚拟语气 本来从句前有一个IF的(如果) 将从句倒装就可以将IF省略(如上) 本来是这个样子:If they were to arrive before we leave,the day after tomorrow, we should have a wonderful dinner party.
