There are many commonly held beliefs about eye glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes. We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight. Another myth about eyes is that they can be replaced, or transferred from one person to another. They are close to one million nerve fibers that connect the eyeball to the brain, so it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible. With the technology we now have, doctors _ . A) can transfer certain parts of the eye in a new person B) can transplant the whole eye in a new person C) still can't do eye transplant even certain parts of the eye D) know almost nothing about eyes

A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as "greenhouse gases". And the way in which they trap heat in the atmosphere is called the "greenhouse effect". This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us. The problem is that in the last century and a half, we have been putting too many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth's temperature of between I and 4degC;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased. Which of the following is not true? A) Burning too much coal and oil produces lots of greenhouse gases. B) It has become warm on the earth now than in the past. C) Gases put into the atmosphere now will affect the earth years later. D) The temperature in a greenhouse is as high as that in the atmosphere.

Ques: When buying from a dealer, the law says that a car must be: As described: This includes the history of the car as well as its specification.For example, if the dealer described the car as previously having "one careful lady owner", it shouldn't turn out to have had several previous "boy racer" owners. Of satisfactory quality: It must meet the standard that a reasonable person would regard as acceptable and be free from any quality problem.Also, bear in mind that a second-hand car will have a slightly different definition of what is considered "satisfactory, because there's certainly an element of wear and tear. Fit for the purpose: It must be reasonable fit for any normal purpose and this includes any purpose that you specify to the seller. *If any of the above is violated, then in theory, you may have the right to reject the vehicle and get your money back if you're reasonably quick. Alternatively, the dealer might offer to replace or repair the car; reduce the price of offering a partial refund .Once you've informed the dealer that you wish to reject the car , you must stop using the vehicle. *If the rejection is not accepted, then it's up to you to prove your case. You'll need to pay for an independent assessment of the car and sue(,)for damages. If you do choose a repair, insist the dealer provide you with a hire car or pay any reasonable traveling expenses thus produced while your new car is in the garage. *If the car is new, it's likely that the claim will be too high to be fought. Using the small claims procedure to you may have to pay for legal representation. All this can be pretty _ and expensive. You need to weigh up the pros and cons before rejecting a car. Would a repair do just as well? Selecting a dealer who offers a clear exchange policy may help. After reading the passage, you will be better at _ . A) choosing a car B) making a claim C) dealing with car sellers D) suing for damages
Ans: C
Ques:Although he will always be remembered for starring "Superman," the greatest role of actor Christopher Reeve's life was as a champion of sufferers of spinal cord injuries and an supporter of stem cell research. Unlike the man of steel, he wasn't faster than a speeding bullet, more powerful than an engine and he couldn't leap tall buildings in a single bound. But the courage and determination Reeve showeed in trying to overcome his paralysis from a 1995 horse-riding accident went beyond any of the achievements of the comic book hero. "He became a real-life Superman. His heroism, his courage was extraordinary," Colin Blakemore, the chief executive of Britain's Medical Research Council said. "Like many people who suffer some terrible injuries, Christopher Reeve was totally changed by that experience and brought the kind of energy and enthusiasm that made him successful as a film star to an entirely different issue, with huge effect." Reeve, 52, died of heart failure on October 10, 2004 after having treatment for an infected pressure wound without realizing his dream of walking again. But in the nine years since his accident, he made personal progress to regain respect and admiration, founded the Christopher Reeve Paralysis Foundation, a non-profit research organization, and used his fame to raise millions of dollars for research into spinal cord injuries. He also provided hope and inspiration to other patients and made speeches to support scientists to be allowed to conduct stem cell research in the hopes of eventually curing paralysis and other illnesses such as diabetes and Alzheimer's and Parkinson's disease. "He has been our champion. If you think of spinal injuries, you automatically recall a picture of Christopher Reeve," said Paul Smith, executive director of the Spinal Injuries Association in England. It is because of Reeve that spinal cord injuries and stem cell research are so widely discussed, according to Smith. The fact that it happened to Reeve showed it can affect anyone, even Superman. Reeve... It can be implied from the passage that _ . A) Reeve remained optimistic after suffering from paralysis B) stem cell research has long been a controversial subject C) paralysis can happen to anyone no matter how strong he seems D) some presently incurable illnesses are to be cured in the near future
