1、直到完成了工作，你才能回家。
util you finish the work, then you will be able to go home, 中文有这样的说法，但英文不会是这样说的。英文的说法应该是，you have to finish the work before go home. 你得在回家前完成工作。 而且我看了，以下的句子也都是与时间副词有关的条件语法。
2、回到家后，他休息了一会儿。
He takes a rest after he back home.
3、当春天来临时，到处是鲜花。
bloom every where when spring is coming
4、我一到那里，天就开始下雨。
it starts raining when I arrive there.
5、我们到家的凯或岁时候天已经黑了。
it was dark when we arrived home.

当……。正……。
注意时态也是有团绝变化，但前后要一致就好， 我上盯睁面例子就有，请看一下。

1. You can't go home until you finish you work.

2. He didn't rest until he got home.

3. Flowers are everwhere when the spring comes.
