题目

They ______ to Guangzhou ______ the train which ______ at 8:00 in the morning.A.will go off
They ______ to Guangzhou ______ the train which ______ at 8:00 in the morning.
A.will go off … by… will leave
B.are going to go off … by … is going to leave
C.are going off … on … leaves
D.are going off … in … will leave
此题选C 请问最后一空为何不用will leave ,
我个人认为火车将在早上八点离开

答案

我记得以前我们英语老师给我们这么解释的：
有时刻表这类单词出现的时候,就算是将来时,单数名词后的动词都只能用V.+s/es.因为火车发车时间已经固定了的,不能说今天是8:00,到了明天就变成另一个时间了吧?对既定的时间和事实,就只能用leaves.
