一个高中英语单选题----------务必高手帮忙
14、If he had spent more time practicing speaking English before,he _____ able to speak it much better now.
A：will be B：would be C：has been D：would have been
答案是选项,可是我好像从来没听说would be 有虚拟的用法,也许我没学到这个知识点,请高手赐教,这是哪个知识点,
答
这是 错综 虚拟语气 也就是 虚拟条件句 与过去相反 用过去完成时
主句与现在相反 用过去将来时
所以 答案是 B：would be
注意 这里选D：would have been是错误的 这是与过去情况相反 的虚拟语气。而本句有时间状语now 所以 错误
答
D 句型啊~if had done, would have done
答
B,就是普通的虚拟语气.这里是错综时间,虽然前面是过去的时态,因为后面的now,所以是现在的虚拟,用would/could/should+动词原形,所以选B
这里最容易错选D是没有注意后面的时间.
