考题 Passage TwoWhat is your favorite color? Do you like yellow, orange or red? If you do, you must be an optimist (乐观者), a leader, an active person. Do you prefer grays and blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. At least this is what psychologists (心理学家) tell us. They have been seriously studying the meaning of color preference (爱好), and the effect that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.A yellow room makes us feel more cheerful and more comfortable than a dark green one. On the other hand, black is depressing. Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.Remember that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.36. According to this passage,______.A. one can choose his color preferenceB. one is born with his color preferenceC. one's color preference is changeableD. one has to choose his favorite color as soon as he can see clearly

考题 Passage TwoWhen we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.People who are nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.People who are nearsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object outof the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.40. We should take good care of our eyes ______.A. only when we cannot see perfectlyB. only when we can see wellC. even if we can see wellD. only when we realize how important our eyes are

考题 What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly. Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue. Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey. "They tell us, among other facts,that we don't choose our favourite colours as we grow up." "Among other facts" means______. a.besides other facts b.in regard to other facts c.not considering other facts d.according to other facts

考题共用题干 Motoring Technology1.2 million road deaths worldwide occur each year,plus a further 50 million injuries.To reduce car crash rate,much research now is focused on safety and new fuels-though some electric vehicle and biofuel research aims at going faster.Travelling at speed has always been dangerous.One advanced area of research in motoring safety is the use of digital in-car assistants.They can ensure you don't miss important road signs or fall asleep .Most crashes result from human and not mechanical faults.Some safety developments aim to improve your vision.Radar can spot obstacles in fog,while other technology"sees through"big vehicles blocking your view.And improvements to seat belts , pedal（脚踏）controls and tyres are making driving smoot- her and safer. The colour of a car has been found to be linked with safety,as have,less surpris- ingly,size and shape.But whatever is in the fuel tank,you don't want a thief in the driving seat and there have been many innovations（创新）.Satellite tracking and remote communications can also come into play if you crash,automatically calling for help.Accidents cause many traffic jams,but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road.Such jams can be analyzed using statistical tools.Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone's personal chauffeur（司机）,but their latest efforts suggest that won't be soon.Satellite tracking and remote communication systems can be used to______.A: reduce oil consumptionB: remove the obstacles on the roadC: call for help when one's car crashesD: help drivers get out of a traffic jam
