2.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.

    Dog speak Voice 解析:基类中有两个虚函数getType( )和getVoiee( ),在派生类中同样也有。函数type和speak的形参都是Animal类的对象,但是一个是引用调用,另一个不是。当用Animal的派生类Dog类定义的对象调用这两个函数时,type函数会转向:Dog类中的成员函数,而speak函数不会。

    Animal Testing Controversy

    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 comes from or is animals一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一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 nee-- ded 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 re-search.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.

    From the text we learn that Stephen Cooper is________.
    A:a well-known humanist
    B:a medical practitioner
    C:an enthusiast in animal rights
    D:a supporter of animal research

    答案:D
    解析:
    第一段中间提到“Scientists need to respond forcefully to animal rights advocates...”意思是科学家们需要采取行动回应这些动物权利的鼓吹者。这实际上就是一个呼吁,所以答案应该是A。
    第一段最后一句说,被误导的人们“听到医学实验残忍对待动物的指控时,许多人都不明白为什么有人会故意伤害动物”。第二段举了被误导女士的例子,她反对用动物来做研究。第三段最后一句,这些人认为“动物实验说得好是浪费,说得不好是残忍”。A 内容不完整。inevitable:不可避免的;vicious:危险的,所以选项B正确。

    正确答案: G
