know that animal research saves lives. I am concerned about deceptive claims from anima rights activists about the need for animal research. As we know, animal studies continue to be necessary for advancing human and animal health and have played a vital role in every major medical advance. This includes lifesaving drugs, vaccines (疫苗), new surgical procedures, and improved diagnosis of disease.Animal activists try to deceive people and count on society’s general lack of scientific insight to advance their agendA.These activists misrepresent the ability of computers and emerging scientific techniques to serve as substitutes for animal studies. Government regulations around the world require that new drugs, vaccines, and surgical implants first be tested in animals for potential reactions to poisonous substances. Beyond these formal legal requirements, research into the root causes of disease and how diseases become resistant to current treatments cannot be simulated by computer programs or imitated in test tubes.Although present-day technology cannot yet replace many types of animal research, the research community is committed to finding new ways to reduce and replace animal testing. Animal studies are time-consuming and resource-intensive. If meaningful alternatives exist, companies can save hundreds of millions of dollars in facilities and personnel costs. Concern about animal welfare can take very different forms. Some people are offended by the use of leather and fur as fashion but accept that medical research must unavoidably use animals until alternatives are founD.Some groups argue persuasively against intensive farming practices but, again, recognize the need for animals in medical research.My advice is that people carefully consider not just whether or not a group shares their beliefs, but whether or not they behave morally. The strategies used by opponents have included false claims about alternatives to animal testing and misinformation aimed at provoking community concerns about potential disasters. Fortunately, very few people support such extreme views. Surveys show that most Americans support the need for animal studies aimed at medical advances. There is agreement on one key issue: We all look forward to a day when mankind’s wisdom provides a way to completely eliminate the need for animal studies.

A prescription is as personal as your name. It is designed for you alone. It is based on such factors as your age, weight, general health, allergies (过敏症), and other factors, as well as your illness.
Never take a prescription drug meant for another person, even if you think you have the same illness. Prescriptions aren't supposed to be traded around the family or neighborhood. Each prescription is intended for an individual. It is a violation of federal law to sell a prescription drug without a prescription.
Doctors and dentists are licensed by each state to prescribe drugs for human use. Doctors for veterinary (兽医的) medicine are licensed to prescribe drugs for animal use.
A licensed medical doctor must pass all examination m practice medicine in a certain state. Before doing this, he or she has probably completed at least two years of a premedical course, a four-year medical course, two years of internship (实习) or residency in a hospital, and perhaps an extra year or more of training in a specialty -- altogether at least eight years of medical training, possibly nine.
Don't take prescriptions written for you during a previous illness without first checking with your doctor. Your illness may not be the same as the previous one, even though you think it is. Also the drug may have lost strength. Only a doctor is qualified to advise you about continuing to take a medicine.
Why does the law require that some drugs be used under a doctor's prescription？
A．Because they are not safe.
B．Because they need further special tests.
C．Because they are meant to cure serious diseases.
D．Because the prescription can ensure the safe use of the drugs.
