下面是一道月考题:
Many adults learn English, because it is _______ (use) in their work.
正确答案为 useful,但我写的是 used,可以吗?但是我觉得,它们只是含义不同,但语法都没有错,是这样吗?
就 Many adults learn English, because it is _______ in their work.而言,填 useful 或者 used 都是正确的,只是句子结构和含义不同而已:
(1) Many adults learn English,because it is _______ in their work. 填 useful,是形容词作表语,句子的意思是:很多成人学英语,因为它(英语)在工作中有用。
(2) Many adults learn English,because it is _______ in their work. 填 used,则 is used 是被动语态,句子的意思是:很多成人学英语,因为在工作中使用英语。
