　　【教学难点】

　　【教学过程】
　　Step 1  Language practice
　　To master the use of “although, that, but” by filling the blanks.
　　1. I can look after myself,________ it won’t be easy for me.
　　2. ________ they loved me, I felt a bit unhappy with them.
　　3. My clock rings____ loudly _____ it will certainly wap.
　　Step 2 Grammar结果状语从句和让步状语从句
　　1. so…that…引导的结果状语从句
　　so…that…结构的意思是“太……以至 于……”。so后面接形容词或副词, 表示程度, that后接从句表示这一程度造成的影响或结果。
　　e.g. We were so noisy that our next-door neighbour came to complain.
　　我们太吵了, 以致隔壁邻居前来抱怨。
　　I was so careless that I forgot something important.
　　我真是粗心, 以致忘记了重要的事情。
　　He speaks so fast that I cannot understand him.
　　他说话太快了, 以致我没理解他的意思。
　　2. 让步状语从句
　　although引导的让步状语从句, 表示“尽管……, (但是)……”。
　　e.g. I can look after myself, although it won’t be easy for me.
　　我还是可以照顾自己的, 虽然这对我来说不容易。
　　Although Kevin is alone, he is ver y happy at first.
　　尽管凯文独自一人(在家), 但他刚开始还是挺高兴的。
　　让步状语从句也可以由though引导, 表示表示“尽管……, (但是)……”。在一般情况下, 可以与由although引导的让步状语从句互换使用。在口语中, though较为常用。
　　e.g. He went on fighting, though he was wounded.
　　尽管受了伤, 他还是继续战斗。
　　注意: 汉语中“虽然/尽管”与“但是”往往同时使用, 但在英语中却不是这样。
　　e.g. I do not often make dinner, but I can cook.
　　我不经常做饭, 但是我会做。
　　Although I do not often make dinner, I can cook.
　　虽然我不经常做饭, 但是我会做。
　　对比这两个句子可以看出, 在英语中，although与but通常是不能同时使用的。
