问题 Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell ff the cause is a cold or fin may make a difference in how long the misery lasts.
    The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys in being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking overthecounter remedy, the sooner relief will come.
    The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B, and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA.
    But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are more obvious signs to look for.
    Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.
    The ALA notes that it may be particularly difficult to tell when infant and preschool age children have the flu. It advises parents to call the doctor if their small children have flulike symptoms.
    Both cold and flu symptoms can be eased with overthecounter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome, a rare but serious condition of the liver and central nervous system.
    There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.

If children have flulike symptoms, their parents ______.
选项 A、are advised not to give them aspirin
B、should watch out for signs of Reye syndrome
C、are encouraged to take them to hospital for vaccination
D、should prevent them from mixing with people running a fever
答案A
解析 细节判断题。根据倒数第二段的第二句转折词However之后的信息“children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome a rare but serious condition of the liver and central nervous system．”小孩子和青少年患者应避免服用阿斯匹林止痛，因为那样有可能引发Reye综合症，这种肝部和中枢神经系统的并发症虽罕见但却非常危险，由此可见A项正确而B项错误，C项是预防flu的措施，文章最后说预防伤风的措施之一是远离患者，而不是有流感症状时避免孩子与发烧人群接触，故D错。
