World War 2( )when Anthony started school in 1942.
A had been fought B was fighting
C was being fought D was fought
我的问题是：fought 不是也有过去式表被动的用法,be done 也表示被动,如何区分?为什么这题得选C不选B?
World War 2( )when Anthony started school in 1942.
第一,这里注意,是被动语态.B选项是主动语态进行时.战争是被人类进行的.
第二,此题应用被动语态,但是需要表明正在进行,正在进行是需要加-ing的.那怎么办?就需要加一个being表明正在进行,原动作保持被动语态过去分词形式不变就好了.
再问： 谢谢您的回答，那be done 和过去式表被动怎么区别呢？
再答： 嗯，这个问题是个语法难题。 给你举个例子吧，我都有当老师的天分了。 1.The homework is finished.这里是被动语态，标准的。 2.The homework finished by me is very good.这就是过去式表被动。 你要记住，过去式和过去分词是不同的，两者不可混淆。被动语是用的过去分词，而不是所谓的过去式。 使用被动语态还是过去分词表被动，取决于句子的结构，就像我给你举的例子。。我能说的就这么多了。
