until前的动词要使用什么形式

问题描述

精选答案

1. until用在肯定句,谓语动词通常是延续性动词,如stand, stay, talk, wait等,表示主句动作终止的时间。

如:③I waited until he came back.我一直等到他回来。

④The war lasted until 1945.战争持续到1945年。如果用在否定句,谓语动词通常是瞬间性动词,如open, start, leave, arrive, finish, stop等,强调主句动作开始的时间。如:⑤I didnt leave the boy until his mother turned up.直到这孩子的母亲来,我才离开。

⑥The noise of the street didnt stop until it was midnight.街上的噪音直到半夜才停止2.连词until引导的从句中谓语动词的时态1)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
