问题     When a drug is one that should be used only under a doctor’s supervision, the law requires that it be sold only by prescription (处方). Special tests or instructions may be needed. Drugs for serious diseases may require a prescription to insure safe and correct use.
    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 shouldn’t you continue to take the same medicine for the same illness without your doctor’s permission?
选项 A、Because some medicines may have side effects.
B、Because there will be better medicines for your illness.
C、Because your illness may become more serious.
D、Because the effect of some medicines may be lost.
答案D
解析 此题问为什么在没得到医生允许的情况下，即使犯了老毛病你也不能继续服用以前用过的药。文章的最后一段说明了其中的原因。根据“Also the drug may have lost strength．”可以看出，D项符合文章的意思。A、B、C三项的内容与文章有出入。
