重点语法：时间状语从句
考向1：
1. until作连词, "直到……为止",引导时间状语从句时,需注意:
主句是肯定句时,其谓语用延续性动词,强调主句的动作或状态一直持续到从句的动作发生时为止, "直到……为止"
I’ll stay here until you come back. 我会待在这里,直到你回来。
2.主句是否定句时,其谓语用非延续性动词,强调主句的动作在从句的动作发生之后才开始, "直到……才……"
(1) We cant get off the bus until it stops.
直到公共汽车停下来时我们才可以下车。
(2) We didnt start our discussion until he arrived.
直到他到了,我们才开始讨论。
例题：
-- Do you know the traffic rules?
--Sure,one of them is that we can’t go across the street____the light is green.
A. until B. after C.if
考向2：
so that 意为"为了,以便，引导目的状语从句,相当于in order that，从可中多含有can 、 could 、 may、might等情态动词。
I took a taxi so that I could get there earlier.
我搭了一辆出租车,为的是能早点儿到那儿。
【拓展延伸】
so that还可引导结果状语从句, "因此;所以"。此时从句中通常不含情态动词。
The movie was boring so that half of the audience was asleep.
这部电影太无聊了,所以—半儿的观众都睡着了

although “尽管；然而”引导让步状语从句，相当于though
1.Although we are neighbors, I dont know them well.
尽管我们是邻居，但我对他们却不太了解。
2.Although she was in poor health, she continued to carry out her duties.尽管她身体不好，但仍然继续执行任务。
{易错警示]
although或though不能与but用在同一句子中,但可以与yet still同时使用。
