题目内容
15.Autumn and winter are cold and flu(流感) seasons.Will the old advice about dressing warmly help prevent a cold,or if you get sick,should you follow the old saying,"feed a cold and starve(挨饿)a fever"?And what about that fever?Should you take medicine to reduce your temperature,or is it better to let the body treat the fever itself?Everyone seems to have an answer.But is popular wisdom valuable?Doctor Nelson knows a lot about cold and flu seasons.Nelson says research may be just starting to provide proofs (证明) for long-held beliefs.For example,scientists for years were against the idea that getting cold and wet might cause colds or flu.But recent studies have shown that cold temperatures cause stress on the body,and that stress can create something more likely to lead to viruses.So maybe it is really important to wear warmly before going outside.
And what about feeding a cold and starving a fever?Nelson says if you have a cold and are hungry,you should eat.But a fever,especially a high one,suggests a more serious problem.He says people are usually not hungry when they have a high fever.Eating might even make a person sick.But drinking enough water is important.A fever easily makes the body lose water.
Finally,when should you treat a fever?Nelson says a fever should be treated if it stays at 40℃or above for a day or more.A high temperature can damage(破坏) brain cells(细胞).The doctor also believes in treating a fever if it prevents a person from sleeping.
Medicine like aspirin,for example,can be used to reduce pain and fever.But aspirin should not be given to children because it can cause serious problems.

A.Why people should eat when having a cold.
B.When people should treat a fever.
C.What the medicine,aspirin,is used for.
D.Whether the old advice about preventing a cold is valuable.

分析 每个人都有自己的答案,但是在流行的说法中有有多少有价值的呢?
加利福尼亚州的阿尔文-奈尔森-艾尔-阿敏博士对于一般性感冒和流行性感冒很有研究,他是芝加哥免疫工程的用药指导.
尼尔森博士说研究只以为许多长久存在的认识提供证据开始,比如,很多年来科学家都对寒湿导致一般性和流行性感冒的说法嗤之以鼻.
但是近期的研究表明低温给身体带来压力,这种压力将给病菌入侵创造更有利的条件,所以外出前注意保暖对防止感冒能起到一定的作用.
那么"伤风时宜吃,发烧时宜饿"这个建议又怎么样呢?尼尔森博士说,感冒时候如果感觉饿了就应该吃东西,但是发烧的话,尤其是发高烧,就建议更加严肃的对待.
他说人们在发高烧时通常不感觉饿,吃东西会使他们呕吐,但是要喝很多水,这是很重要的,因为发烧很容易使身体脱水.
最后一个问题,应该什么时候去采取措施治疗发烧?尼尔森博士说在持续一天以上发烧达到或超过四十摄氏度时就应该治疗了.高烧会损害脑细胞,他也认为在发烧导致无法入睡也要进行治疗.
阿司匹林,退热净和布洛芬都可以用于减少病痛和发烧,但是由于阿司匹林会引发一种罕见症状,所以不能给儿童服用.
解答 28.答案:D.推理题:从文章第四段的句子Nelson says a fever should be treated if it stays at 40℃or above for a day or more.说明如果发高烧达到40度以上长达一天多,就要治疗了,也就是如果刚刚发烧达40度,就没必要治疗.选D.
39.答案:B.细节题:从文章第三段的But drinking enough water is important.可知喝水很重要.选B.
40.答案:A.排除题:B项是出现在第四段.同第一题的解析,文章的第二段Nelson says research may be just starting to provide proofs for long-held beliefs.说明D项正确,文章最后一段的Medicine like aspirin,for example,can be used to reduce pain and fever.说明C项正确,就是没提到A.
41.答案:C.细节题:从文章的最后一段的:But recent studies have shown that cold temperatures cause stress on the body,and that stress can create conditions more inviting to viruses.说明身体有压力的时候很容易生病.选C.

Do you often use a cell phone?Do you take the subway to school every day?These items make our modern life easier.But do you know how we should behave properly while using them?The following suggestions might be helpful.
For cell phone users
◆Keep your voice down when you make a phone call in public.Shouting on the phone may make others feel uncomfortable.And you'd better not use it during a meeting.
◆Don't send messages at a dinner or a party.You shouldn't play cell phone games either.It's a good time to communicate with your family and friends.
◆Don't make or answer a call while driving.It is not only very dangerous for both you and your passengers but also against the law.
For subway(地铁) passengers
◆You are supposed to wait in a line while buying tickets and getting on the subway.
◆According to subway rules,you mustn't eat,drink or smoke on the subway.The smell and noise may trouble others.It's necessary to keep the train clean and tidy.Besides,smoking is bad for your health and harms people around you.
◆You'd better not lie across the subway seats even if the train isn't crowded.Offering your seat to someone who needs it is considered as good manners.
