Not only Mary but also her brothers are going to dance. 4, because和 so because 与 so在英文中两者不能并用的，只能在句中用其一。如， He didn't go to school yesterday because he was ill.  He was ill, so he didn't go to school. 5.由when，while, before, after, as soon as, until, if， unless等引导的含有时间和条件状语从句复合句，在谈论将来事情时，符合“主将从现”， 即主句一般将来时，从句一般现在时。如， I don’t know if it will rain tomorrow. If it doesn’t rain tomorrow, I will go fishing. Tom will call you as soon as he reaches Beijing. 即时训练 一、 单项选择 1· —Did you enjoy yourselves in the park? —Yes.
