请解释并说出“before，until，as soon as，after，while，when”等词的用法及意思 再帮我补充一些

谢啦

在....之前  He will leave here before Monday.

直到.....才... I dont go to bed until 10.

一....就..... I will call you as soon as i arrive home.

在.....之后 the students play games after class.

当...的时候(表示两件事同时进行的) Mum is cooking while Dad is reading the newspaper

当...的时候(两件事不是同时进行的) He fixes the bike when the doorbell is ringing.

before 在...以前，介词，一般后面接doing sth.如：I play volleyball before I doing my homework.

常用短语：before long不久之后 before sunset 日落之前

until 直到...才 一般与not连用，如：I didn't sleep until I finished  doing  my homework.

until june 直到六月

as soon as不久之后 常用短语：as soon as possible 尽可能地，如：We need to send the letter off as soon as possible.

as soon as not 宁可

after在..之后，后面一般接时段，如：after a few days 介词，后面接doing sth.

After some time they came out.

while当...的时候，后面加时间段，只能接延续性动词（延续性动词：动作可延续一段时间，而不是瞬间结束

如：work，study，be动词等。）

while引导的从句常用过去进行时，强调主从句动作同时进行时，主句也常用过去进行时

如While I was reading the book，my mom was cooking dinner.

如果主句动作在从句的过程中发生，从句常用进行时。

while可表示对比或相反的情况，意思“而”，表示并列关系 I am good at English while Jim does well in

English.

when引导的从句可以是延续性动词，也可以是非延续性动词（即，瞬间动词，极为短暂，如knock，hit）

when引导的时间从句用一般过去时，主句用过去进行时。

The boy was sleeping when his mom got back home.

（补充：in ，还有一个意思，就是在...之后，一般用于将来时态，in three days 在三天之后，若是问，就要用How soon）
