Question

Mr,Well,together with all the members of his family,( )for Europe this afternoon .C is leaving D leaves
我在语法书上看到:1表示按规定要发生的未来的动作(只限于go come leave等）如the train leaves at three this afternoon .我还看到有时表示即将发生的动作（只限于go come leave等）the ceremony is beginning at four o'clock.我想问的是这2种情况怎么区别呀,都是未来嘛

Answer 1

先看题目,在这题中
is leaving=is going to leave=will leave
没有一本语法书是权威,因为一种语言是一个民族的习惯
习惯是不一定都有法可依的.
就如
the train leaves at three this afternoon
是一种比较随便的用法
正式英语应该说
the train is going to leave at.
或者
the train will leave at...
同样
the ceremony is beginning at four o'clock也只是口语化的表达
应该改为the ceremony is going to begin at...
或the ceremony will begin at...
送你一句话：学语言不要完全死般书本,要活学活用
