Passage FourNews has just been received of an air crash in the north of England. The plane , which was on a charter flight from London to Carlisle, was carrying a party of businessmen on their way to a trade fair. It seems likely that the plane ran into a heavy fog as it was approaching Carlisle and was obliged to circle for some twenty minutes. Everything seemed to be going well. The pilot was in constant radio communication with Ground Control when the engines suddenly cut out and all contact was lost. The plane crashed on the site of the ancient Roman camp at Hadrian’s Hill , a place well known to archaeologists(考古学家)and tourists.
So far few details have been reported, but it is feared that at least twenty people lost their lives, among them the pilot, who was killed instantly, The local ambulances and firemen were on the scene within minutes of the crash , but additional help had to be rushed from other areas.
Mr. Lesilie Collins, one of the survivors, told our reporter, “We passengers noticed the engines were making a funny noise. Of course we couldn’t see anything because of the fog, but the pilot said there was nothing to worry about. The next thing we know, the engines went dead. There was a rushing noise-and after that I don’t remember any more.”
Mr. Collins is now in hospital, being treated minor injuries. We will be bringing you further news of crash as we receive it . In the meantime relatives are asked to ring 02-3457211 for information.

For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from or is tested in animals — no meat, no fur, no medicines. Asked if she opposed immunizations, she wanted to know if vaccines come from animal research. When assured that they do, she replied, "Then I would have to say yes." Asked what will happen when epidemics return, she said, "Don't worry, scientists will find some way of using computers." Such well-meaning people just don't understand.
Scientists must communicate their message to the public in a compassionate, understandable way — in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother's hip replacement, a father's bypass operation, a baby's vaccinations, and even a pet's shots. To those who are unaware that animal research was needed to produce these treatments, as well as mew treatments and vaccines, animal research seems wasteful at best and cruel at worst.
Much can be done. Scientists could "adopt" middle school classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and ac- quire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because the ultimate stakeholders are patients, the health research com- munity should actively recruit to its cause not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing, there is a real possibility that an uninformed citizenry Will extinguish the precious embers of medical progress.
The author begins his article with Edmund Burke's words to ______.
A.call on scientists to take some actions
B.criticize the misguided cause of animal rights
C.warn of the doom of biomedical research
D.show the triumph of the animal rights movement
When we see well, we do not think about our eyes very often. (79) 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 seems blurry (模糊的). Many people who do a lot of close work, such as writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant objects clearly.
People who are farsighted 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 olden 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. To prove this to yourself, look at object out of one eye; then look at the same object out of your other eye. You will find the object's relation to the background 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.
We should take good care of our eyes ______.
A.only when we can see well
B.only when we cannot see perfectly
C.even if we can see dell
D.only when we realize how important our eyes are

People who are near-sighted 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 far-sighted 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.

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 out of 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.
