1. since引导的时间状语从句
时间状语从句
since引导的时间状语从句常与完成时连用, 表示“自从…….”。
I have known Bill since he was born.
自从比尔出生起, 我就认识他。
用从句来表达一件事情或一个行为发生的时间, 这个从句就叫时间状语从句。
不同的引导词引导的时间状语从句的意思也不同，常见的引导词有when，while，before，after，until，since和as soon as。
时间状语从句
一、when引导的时间状语从句
when引导的时间状语从句既可以表示点时间，也可以表示时间的延续，即表示一段时间，因此从句的谓语动词既可以是瞬间动词，也可以是延续性动词。此外，从句的动作既可与主句的动作同时发生，也可先后发生。
e.g. When I got home, I found the door open.
当我到家的时候，我发现门是开着的。
I used to like drawing when I was young.
我年轻的时候曾经喜欢画画。
二、while引导的时间状语从句
while引导的时间状语从句表示时间的延续，即表示一段时间，因此从句的谓语动词用持续性动词或状态动词，且持续性动词常用进行时态。此外，主句的动作发生在从句所表示的时间段之内或主从句动作同时发生。
e.g. There was a big noise suddenly while I was cooking.
我做饭的时候突然一声巨响。
He kept working part-time while he was at university.
他上大学的时候坚持兼职工作。
while
“当……的时候”
While we’re staying with our friends, we’re going to spend one day in Qingdao.
While they were crossing the Atlantic, many people died.
I was writing a diary while my brother was watching TV.
While
表示主句的行为在从句行为进行的过程中发生。While 从句要用持续性动词，常用进行时态。
表示两个动作同时进行。
Grammar
When
2. _____ I got home, I found my baby girl singing in the sitting room.
While
1. _______the lights were changing to red, a car suddenly appeared around the corner.
when和while都表示“当……时候”，但while引导的从句常用进行时态。
when VS while
Grammar
before表示主句的动作发生在从句之前。
如:
I won’t tell you the truth before he comes back.
他回来之前我是不会告诉你事实的。
after表示主句的动作发生在从句的动作之后。
如:
After she finished the work, she went to have supper.
她完成工作后去吃晚饭了。
as soon as表示主句的动作紧随从句动作之后发生的。
如:
After she finished the work, she went to have supper.
她完成工作后去吃晚饭了。
表示“一……就”
I will call you as soon as I arrive home.
我一到家就给你打电话。
I hope to find him as soon as possible.
我希望尽可能快地找到他。
Mother became unhappy as soon as I mentioned his name.
我一提到他的名字，母亲就变得很不开心。
2）若since引导的状语从句的谓语动词是持续性动词或表示状态的静态动词（如live, stay, study, learn, smoke, be等）的过去时, 则从句表示的时间是“从该动作或状态的完成或结束时算起”。如：
　It’s ten years since I’ve seen her.
我已经十年没有见到她了。
