三、until，so that，although的用法
1. until的用法
（1）作介词，表示＂直到……为止＂。
The meeting may last until Friday. 会议可能要延续到星期五。
Mark will be working until 5 o’clock. 马克将一直工作到五点钟。
【注意】由上面两个例句可知：until用于肯定句中表示动作一直持续到until短语所表示的时间为止，即表示动作的终点，意为＂直到……为止＂。在这种用法中，句子的谓语动词必须是延续性动词，如：live，wait，last，love，like，stay，work等。
（2）作连词，表示＂直到……为止；在……以前；不到……（不）＂。
①用于肯定句中
Please wait here until I come. 请在这里等到我来。
②用于否定句中
I won’t stop shouting until you let me go. 你不放开我，我就一直喊叫。
【注意】 until作连词用于否定句中，从句的动作先发生，主句的动作后发生，意为＂直到……才……＂。
2. so that的用法
（1）so that引导目的状语从句，从句谓语动词常用情态动词may/might/can/could等。
（2）so that引导目的状语从句，当主句主语与从句主语一致时，可用＂so as to(in order to)＋动词原形＂转化为简单句。
（3）so that还可以与in order that互换。
【知识拓展】
so...that...表示＂如此……以至于……＂，引导结果状语从句。
The boy is so young that he can’t go to school. 这个男孩太小还不能去上学。
3. although的用法
（1）although较正式，引导的从句放在主句的前后均可。
（2）although不能与but连用，但可与yet，still连用。
