Grammar Rules
· 什么是状语从句?
在句中作状语的从句叫状语从句。状语从句可修饰谓语、非谓语动词、定语、状语或整个句子。状语从句一般由从属连词引导,它可以表示地点、时间、原因、条件、目的、结果、让步、比较等。
Teaching Tip:从属连词是用于连接主句和从句的词语,使从句依附于主句,构成复合句。状语从句不能独立成句,必须依附于主句才能表达完整的意义。从属连词有though,although, when, until,after, so that,in order that,if,unless,because,since等。
· although 的用法
让步状语从句由从属连词though,although引导。though,although都意为“虽然”,但注意它们都不能和but在同一个句子中使用。例如:
Although he is quite old,he still jogs every day.
=He still jogs every day though he is quite old.
=He is quite old,but he still jogs every day.
· until的用法
until,till都表示“直到……”。它们都可以作连词,连接时间状语从句;也可以作介词,与其他词构成介词短语,在句中作状语。until和till的语义是相同的,但till主要用在口语中。例如:
We walked and walked till/until it was dark.
We didn't stop walking until it was dark.
Li Ming will wait till/until his father comes back.
Li Ming won't leave here until his father comes back.
· so that 的用法
so that可引导目的状语从句和结果状语从句。当它引导目的状语从句时,从句的谓语里常有can,could,may, might,will, would等情态动词。而当它引导结果状语从句时,则没有上述这些词,而且从内容上看主句和它引导的状语从句有明确的因果关系,主句为因,从句为果。例如:
He always studies hard so that he can make great progress.(目的)He studied hard last term so that he made great progress.(结果)
· if的用法
if 表示“如果”,引导条件状语从句。含if从句的复合句可转换为并列句。例如:
If you use your head,you'll find a way. =Use your head,and you'll find a way.
If you don't hurry up,you'll miss the train. =Hurry up,or you'll miss the train.

Teaching Reflection
The lesson went smoothly overall. Students grasped the usage of adverbial clauses with although,until and so that through practice. Most could finish the exercises correctly, but a few were still confused about their functions. Next time, I'll add more examples to help them understand better.
