【 Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状 况仍将持续。 Until是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在 那个时刻之后，该事情或该状况将中止（不怎么可能持续）。固定组合里 from morning till night，till/until是不能替换的，】

时间状语从句
2.till / until，表示“一直到……”，主从句都用肯定形式；表示“直到……才….”，主句否定 ，从句肯定。
He worked until it was dark. 他一直工作到天黑。 He did not get up till his mother came in. 一直到母亲进来他才起床。
状语 up late.
He got up late.
练一练
He got up late.
He was late for school.
练一练
He got up late.
He was late for school because he got up late.
原因状语从句
2.for意为“因为”，引导的从句并不说明主句行为发生的直接原因，只提供补充说明，且不可位于 主句前。for前往往用逗号或分号与主句分开，引起的从句对主句加以解释。
I didn't go to see him, for a heavy snow was falling. 我没有去看他，因为在下大雪。 The days were short, for it was now December. 白天短了，因为现在已经是十二月了。
让步状语从句
1.although/ though意为“虽然” Although I didn't know anybody at the party, I had a good time. 虽然晚会上的客人我一个也不认识，但我玩得很愉快。
注意： "although...but"是个典型的错误，因为but是并列连词，不能与从属连词although连用。但是， although可与yet或still连用，因为yet，still是副词，它可使前后关系更明确。

I would leave if he came.
I will leave if he comes.
The train had been away when I arrived.
过去配过去
过去配过去
现在配现在
现在配现在

条件，即“在…条件下，某事才能发生”，在句子中充当状 语，因此称之为条件状语从句。
