　　Very few people enjoy exams．I don't , either．And although I tell myself not to worry about them, I always do! So I am not surprised that my students worry about them, too , even though they usually don't need to．Because they are afraid of failing．However, since it is hard not to worry at all, we all must try not to worry too much．Why? Because worrying makes exams worse ! How to do this ?

　　Ask the teacher about how to revise and about exam skills---- how to work when you are in the exam．

　　Good students don't wait until the week before an exam．They study all through the year．It is not possible to learn everything at the last minutes．So don't leave it till then!

　　If you start planning and working for each exam early and you make sure that you understand what you are studying , then, when it is over, you'll be able to say, ‘What a good exam that was!”

　　Take a short rest during your time of work and revision．If your mind is tired, it will not remember well．Work at the time when you know you will work at your best．

　　If you are studying in the evening, don't go straight to bed afterwards．Your mind will still be “going round and round”----thinking that will relax you, and make you think of other things．

　　If you feel bad, talk to someone about your worries．But don't be too relaxed! Some stress over exams makes you work hard for them．

　　The bicycle is one of the simplest yet most useful inventions(發(fā)明)in the world．What is most surprising is that it was not invented earlier, although the great inventor Leonardo da Vinci had drawn pictures for bicycles and also for flying machines and some other things．Those things were not produced(生產)until long after he died．

　　A person riding a bicycle uses little energy(能量)to make the bicycle move, and there is no pollution(污染)at all when you are riding．Even so, in developed countries, most people don’t travel to work by bicycle．It is not because the bicycles are expensive or people feel tired if they ride to work．It’s because the number of cars on the roads becomes larger．It certainly becomes more dangerous to ride a bicycle．As a result, more people put their bicycles away and go to work in their cars and, in this way, the situation(情形)is made more serious．Perhaps the best way to make riding safer and more popular is to create paths(開設通道)only for bicycles, and to make it so difficult and expensive for drivers to take their cars into the city that they will go back to using their bicycles．
