题目内容

12．You can't get good grades _____ you study harder than before．（　　）

A．

B．

unless

C．

when

D．

分析除非你比以前更加努力学习，否则你不会取得好成绩的．

解答答案：B．
本题考查的是从属连词的辨析．根据语境推测句意是"除非你比以前更加努力学习，否则你不会取得好成绩的．"从句意来看，这里需要一个表假设的连词，说明后句是表假设的条件状语从句，结合选项，unless可以引导一个表假设的条件状语从句，意为"除非"，相当于if not．故选B．

点评本题主要考查连词的用法，连词在句子中主要起联系上下文的作用，他们之间的区别就是表示逻辑关系的不同，所以在解题时先要理解上下文含义，然后根据上下文逻辑关系选择合适的连词．连词的用法都比较多，语义之间还有交叉，熟记其基本应用规则，了解其区别，注意固定搭配对象，是做好此类题型的关键．

4．（83）For those of us who are studying at school，the time of exams is very stressful and difficult．Some people find exam times so bad that they become ill，because they are afraid of failing； they are afraid of letting their parents and family down．If exams are really making you ill or worried，don't hide your feelings．Talk to someone about it．Maybe you can speak to a friend，or someone in your family，or teachers at your place of study．If one person doesn't help you，ask someone else．
How to get through exams？Here are some advice：
Ask a teacher or tutor about how to review your lessons，and exam skills-how to work when you are in an exam．
Take short rests during your time of work．If your mind is tired，it will not remember well．
Plan your work：study at times when you know you will work at your best．
Get enough sleep，and eat healthy food．
You need exercise to work well．Walk，run，play sport-whatever you enjoy．
Stop thinking about the future and failing．
If you feel ill，talk to someone about your worries．But don't be too relaxed! （84）Some stress over exams makes you work hard for them．
If it upsets you to talk to your friends about an exam when it is finished，don't do it!In fact，don't even think about the exam you have finished．What is done is done．You cannot change what you have written!
To this advice，we could add：
If you are studying in the evening，don't go straight to bed．Your mind will still be"going round and round"-thinking too much．Do something else，maybe walk or get exercise．Choose something that will relax you，and make you think of other things．
