an impact on Earth by small and large objects such as asteroids and comets. 【101】If a car approached as you crossed the street, would you rush ahead, return to the sidewalk, or stand in front of it and wait for the collision? Are we going to wait for an impact from space, or are we going to take steps to avoid such a disaster? If the future of Earth is to involve the future of society, we should not wait.

【102】Most people do not like too much change, nor do they like to consider altering natural processes. While society has gradually shown a willingness to manipulate human biology to prevent disease, most people are reluctant to consider the possibilities offered by the controversial subject of cloning. 【103】In a similar vein, society seems to believe that it must accept earthquakes as natural and unavoidable, but there are already methods under consideration to avoid as natural phenomena are to deal with, society must not maintain a parochial attitude toward preventing catastrophes that science may help avoid. Now is the time to change our world, to realize that while bad things can and do happen, we may be able to prevent them or at least ameliorate their effects without harming society or our environment. The threat of an impact from space has been considered, and methods to deal with this threat are being discussed. 【104】At the same time, we need to be aware that venturing into space may provide the ultimate answer to whether into space may provide the ultimate answer to whether or not humans can survive another threat, the evolution of our sun. I hope that we are able to develop a willingness to consider new approaches to our environmental and biological problems.

Clearly, science and society are intricately entwined, and as one progresses, so does the other. Pure science, the search for knowledge without knowing where it will lead, is part and parcel of what will make the world a better place for all mankind. The more we learn, the more questions we can ask and the more answers we can obtain. 【105】But as society struggles to find answers to its problems, it would do well to remember that science has touched upon and improved almost every aspect of our lives.We must therefore conquer our fears so that we can continue to progress on all fronts, and explore space as a new frontier that belongs to all of us.

did not respond when her parents spoke to her, and never react to noises. "She doesn't seem to know what is happening around her," she told the doctor. Without examining Amanda, the doctor assured Edith that her little girl was fine.

But when Amanda was not talking by the time she was two, Edith and her husband became more and more anxious.【1】Finally, Edith took Amanda to an ear, nose and throat specialist, who did an auditory brain-stem response test in which clicking sounds sent through earphones are measured in the brain. This examination showed that Amanda was severely hearing-impaired in both ears. The tragedy was that late detection had delayed her language development and threatened, long-term, to hinder her growth socially.

Hearing impairment is one of the most common birth defects in Asia today.【2】Dr. Andrew Smith, medical officer with the World Health organization's Activities for Prevention of Deafness and Heating Impairment Team in Geneva, Switzerland, estimates that 5.5 million children in Asian-Pacific region are deaf or hearing-impaired. He says that the lack of awareness among parents and some physicians about hearing impairment is a major reason for late detection in children.

Choy Kwee Yuen of Singapore initially did not suspect there was anything wrong with his child. At six month, Choy Jing Xian cooed and gurgled like any other baby. But when Jing Xian was eight months old, Choy became concerned. The infant would sleep through loud noises, including slaps of thunder. His doctor referred the boy to a specialist, who found that Jing Xian had a severe hearing impairment.【3】"All babies up to six months old make vocal noises--it's a natural reflex," says the specialist, "It's hard to distinguish between a three-month-old hearing baby and a three-month-old deaf baby."

He also stresses that even children with moderately severe hearing loss may hear loud sounds or react to hand movements.【4】If a doctor tests a young deaf child's hearing by ringing a bell next to his ear, he may react to the movement of hand rather than the sound. Because hearing problems are often not detected, many children muddle along until hearing screenings are given at school. They don't know they have a problem, and their symptoms may be misinterpreted.

【5】Mounting evidence shows that the longer the delay in diagnosing the problem, the more trouble the child has in developing language and social skills.

您也许已经注意到生活和工作中紧密相处的人是如何在举止上趋于类同的。我们常常会不自觉地模仿我们所接近、所爱、所仰慕的人。因此，球迷会模仿某个运动员独有的耸肩行走的样子；一对情人连摇头的方式也相同；而雇员则会学他老板的习惯，也在思考问题时手指间玩弄一支笔。

有影响的人物并非在所有的情形中都有意识地觉察到这种仿效，但是这种仿效的存在会使他感到舒服。如果他确实察觉到别人的手势或动作与他一样，他会感到高兴，因为那意味着他对别人产生影响，他对这些人有吸引力。
