一、宾语从句
　　下面例句中，第一句大家都会写;第二句后是介词后的宾语从句，会写的考生不多，要重点学习

　　Traditionally, the approach is to punish criminals by placing them in prison to pay for what they have done (what 引导宾语从句，作为介词for 的宾语)
　　二、状语从句
　　状语从句花样很多，只要求大家复习两种：if 引导的条件状语从句，和while 引导的让步状语从句
　　if
　　If a student wants to learn about job-specific information, they don’t need to sit in a classroom to get it
　　当然很多学生可能会问到，if 引导的虚拟语气很难掌握，其实如果并不想冲刺7分或7.5分的同学都可以不用掌握，即使需要拿到这样的分数，用虚拟的情况都比较少，所以考生可不必在此花费大太的功夫
　　While
　　While the economic development has made our life more comfortable, it has also polarized the society in the distribution of wealth
　　While traditional buildings might look mice from the outside, they are often not very user-friendly
　　三、定语从句
　　复习三种就可以

　　Students who…… ……的学生……
　　Children who…… ……的孩子……

　　2先行词it 开始的主语从句

　　This is because it is the rich and powerful people in our society who are able to impose changes.
