Text 2 To paraphrase 18th-century statesman Edmund Burke,“all that is needed for the triumph of a misguided cause is that good people do nothing.”One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal. 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 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's 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 new 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 acquire 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 community 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.

A moment's drilling by the dentist may make us nervous and upset. Many of us cannot stand pain.

To avoid the pain of a drilling that may last perhaps a minute or two, we demand the "needle"— a shot of novocaine (奴佛卡因) -that deadens the nerves around the tooth.

Now it' s true that the human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us adjust to the world. Without our nerves—and our brain, which is a bundle of nerves— we wouldn't know what's happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain.

But there is a way to handle pain. Look at the Indian fakir(行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain; This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain.

The big thing in withstanding pain is our attitude toward it. If the dentist says, "This will hurt a little, it helps us to accept the pain. By staying relaxed,' and by treating the pain as an interesting sensation, we' can handle the pain without falling apart. After all; although pain is an unpleasant sensation, it is still a sensation, and sensations are the stuff of life.

26. The passage is mainly about______.

A) how to stiffer pain

B) how to avoid pain

C) how to handle pain

D) how to stop pain

B. blame him for his lack of responsibility

Why are so many people so afraid of failure? Quite simply because no one tells us how to fail so that failure becomes an experience that will lead to growth. We forget that failure is part of the human condition and that every person has the right to fail.

Most parents work hard at either preventing failure or protecting their children from the knowledge that they have failed. One way is to lower standards. A mother describes her child’s hastily making table as ―Perfect! even though it couldn’t stand on uneven legs. Another way is to shift blame. If John fails science, his teacher is unfair or stupid.

The trouble with failure-prevention methods is that they leave a child unequipped for life in the real world. The young need to learn that no one can be best at everything, no one can win all the time —and that it’s possible to enjoy a game even when you don’t win. A child who’s not invited to a birthday party, who doesn’t make the honor roll or the baseball team, feels terrible, of course. But parents should not offer a quick comfort prize or say, ―It doesn’t matter because it does. The young should be allowed to experience disappointment —and be helped to master it.

Failure is never pleasurable. It hurts grown-ups and children alike. But it can make a positive contribution to your life once you can learn to use it. Step one is to ask ―Why did I fail? Control the natural impulse to blame someone else. Ask yourself what you did wrong, how you can improve. Second, is the goal you’re to reach the right one? Think about this question. ―If you dosucceed in this, where will it get me? This may help you prevent failure in things you shouldn’t be doing anyhow. The third thing to keep in mind about failure is that it’s part of life. Learn to ―live with yourself even though you may have failed. Remember, ―You can’t win themall.
