1、“直到”你学会until“为止”,主讲人:曾彩霞 2018年1月28日,until既可以用作介词,又可用作连词。作介词时,后面要接具体的时间;作连词用时,后面要接状语从句。,I shall stay here until the next day.,I will keep singing until I get too old to sing.,介词,连词,until,在肯定句中,意为“到为止”谓语动词一般要求是延续的,如:work,live,stay,study,play,wait等,表示动作一直延续到until所表示的时间为止。,until,【练一练】,Things went well _
2、 one night an accident happened.,我想在这儿呆到圣诞节。 _.,until,Id like to stay here until Christmas,until,Notuntil在否定句中,意为“直到才”,表直到until所表示的时间才发生。,The little girl didnt fall asleep until her mom read a story.,基本结构:not主句+until从句,主句,从句,not until,They didnt stop getting on the train until it was full.,not until
3、,I didnt realize she was a famous star until she took off her sunglasses.,not until,【练一练】,You cant have this football back _ you promise not to kick it in class.

5、 not . until :直到才,易错点: 1.何时用until 和notuntil (从时间轴分析:until用在时间点前、not until用在时间点后) (从中文分析: 看句中中文:until直到 , not until直到才) 2.连词until引导的从句中谓语动词的时态: 主句一般现在时,从句一般现在时/ 现在完成时。 CC doesnt wake up until I come back everyday 主句一般将来时,从句一般现在时/ 现在完成时。 CC wont stop eating until I say “NO”. 主句一般过去时,从句一般过去时/ 过去完成时。 CC didnt go back home until it was dark yesterday. 3.连词until引导的从句中谓语动词的类型: until :直到为止(肯定句),主句动词必须是延续性动词。 not until 直到才(否定句),主句动词必须是非延续性动词。,
