until用法归纳

使用注意事项：

◇注意事项一

until用于肯定句中，表示主句的动作一直持续到从句动作发生或状态出现时为止。一般可译为“……直到……为止”。在这种用法中，主句的谓语动词必须是持续动词(非瞬间动词)，如live, wait , last, love, like, stay, work, continue 等。

until用于否定句中,表示主句的动作在从句的动作发生之前尚未发生，或者说主句的动作在从句的动作发生之后才开始。一般可译为“直到……才”。

◇注意事项二

until后面的从句中不能用一般将来时，应该用一般现在时代替。所谓的“主将从现”。

He will stay here until his mother comes back.

They will study at the school until their parents come to take them home.

◇注意事项三（该考点为高中内容）

till和until的意思基本相同，用法也基本一样，但until语气较重，多用于较正式的文体里。till多用于英式英语，until多用于美式英语；till不能用在句首，也不能用在not开头的短语或从句里，而until可以。在这种情况下应用倒装语序。

Until he came home, we knew the news. 在他到家之前，我们不知道这消息。Not until nine o’clock yesterday evening did we fi nish the work.

直到昨晚九点，我们才完成这项工作。

◇注意事项四(该考点在初中阶段基本不涉及)

until与before在多数情况下可以替换。意义差别不大。

不可换用的情况：主句为肯定句，且谓语动词为瞬间动词，只能用before不能用until。这时候before常意为“没来得及……”或“……才……”等。
