注意事项
时间状语从句
when, while, as, before，after, since，until, the moment等
When I was walking along the street, I met a friend of mine.
I will tell him the news the moment he comes.
要注意时态一致，一般情况下，在时间状语从句中，表示将来的动作用一般现在时(不可用将来时)
地点状语从句
where, wherever
Where there is a will, there is a way.
We are always welcome wherever we go.
注意不要和where引导的定语从句混淆，若是定语从句，where前必然有先行词
条件状语从句
if, unless, as/so long as, on condition that, in case等
You should go to school unless you are seriously ill.
He will certainly pass the exam next term if he works hard at his lessons.
条件状语从句和时间状语从句一样，当主句是将来时的时候，从句要用一般现在时
原因状语从句
because，since，as，now (that)
He didn’t go to school because he was ill.
As he is a League member, he takes the lead in everything in his class.
①because语气最强，回答why提出的问题；since次之；as最弱；
②as引导的从句往往放在主句前面，for后面的并列分句往往表示一种附带的解释或说明
让步状语从句
although, though, as, even if/though，whatever, however, whoever, no matter what/who/how
Although he is a child, he knows a lot.
Tired as/though I was, I went on with my work.
①当用though或 although引导从句时，后面的主句不能有but；
②as引导的让步状语从句必须把表语、状语或动词原形提前
I will go and attend the meeting however busy I am.
结果状语从句
so ...that ..., such ...that ..., so that
He runs so fast that no one can catch up with him.
It was such an interesting novel that I read it three times. I got up late so that I missed the early bus.
