请教专家:
1a:Many of the pilots were to achieve eminence in the aeronautical world.
1b:Many of the pilots were to have achieved eminence in the aeronautical world.
2:If it were to rain tomorrow, we would stay at home.
关于were to的问题,
(1)1a和1b显然不是虚拟语气,书上说这种were to是表示过去的安排,打算,注定,预计,这种说法怎么理解,是否正确?
其中,在这种用法下,were to 和 were to have 含义有何不同?
(2)2是虚拟语气,were to 用作表示将来的虚拟语气中,我的困惑是,1a,1b中的were to 和 2中的were to 是同一个用法,同一个含义吗???
还是完全不同的2种were to用法?我们很多同学都很混淆,把上面的were to 都理解成一样的用法,错了吗?
还麻烦专家澄清一下,谢谢。
