An active lifestyle offers a good way of protection from these health problems.”不運(yùn)動(dòng)會(huì)增加青少年患多種疾病的風(fēng)險(xiǎn)。積極的生活方式是預(yù)防這些健康問題的好方法。可知“As much as 75 percent of healthcare spending goes toward treating medical conditions that can be hindered by lifestyle changes”的意思是多達(dá)75%的醫(yī)療支出用于治療可能因生活方式改變而受阻的疾病?！癶indered”的意思是受阻，故選B。 （3）考查推理判斷。根據(jù)最后一段中的“Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.”不參加體育活動(dòng)的學(xué)生，把額外的時(shí)間用于課堂學(xué)習(xí)，在考試中的表現(xiàn)并不比那些為了支持體育而放棄一些學(xué)習(xí)時(shí)間的學(xué)生好。由此推斷出，根據(jù)PCFSN，做運(yùn)動(dòng)幫助學(xué)生在學(xué)習(xí)上做得更好。故選D。 （4）考查主旨大意。第一段中的“But should high school students have physical education?

Taking them for just a week can increase your risk of heart attack by 50%. The research suggested that the risk related to the use of certain drugs was greatest with higher doses (服用量) and during the first month of use. The potential risk may increase by 75% for medicines like ibuprofen (布洛芬) and naproxen, and more than 100% for rofecoxib. It all sounds bad but, your risk is very low, — say, one in a million — a 100% increase means you still only have a two in a million chance. Of course, all painkilling medication that works can have side effects — nothing is safe and effective. Paracetamol (撲熱息痛) has very few unless taken too much, in which case it can cause serious liver danger, but it isn39。t very effective. Drugs like opiates are strong painkillers but easy to be addicted and often have other bad effects. Maybe you find that you are in a dilemma now. But don39。t despair。 you can refer to a pain clinic for some professional guidance. For ongoing pain, music and exercise may be the best choices to help you reduce the feeling of it. Scientist at Harvard have recently done a quite horrible study on mice. They made the mice experience extremes of hot and cold, applied pressure to their back legs and injected the capsaicin (辣椒素) into their feet. And then they timed how long it took them to respond to the pain. Lack of sleep increased the disfort, while stimulants (興奮劑) such as caffeine made them less responsive to pain. This has been widely reported that a good night39。s sleep and a cup of coffee in the morning may help reduce pain. But anyway don39。t throw the pills away because the study also shows taking small doses of drugs, such as for short periods of time can be effective and safe as long as your heart is in good condition.（1）Which of the following painkillers has fewest sideeffects? ....（2）What does the underlined word “despair” in Paragraph 2 refer to? it seriously. any risks. hope. doubtful.（3）The example of mice is used to show that ____ can stand extreme pressure sleep and coffee may decrease pain and feet are more sensitive to pain and stimulants can help reduce pain（4）What is the text mainly about? to stop taking painkillers. new way of reducing pain. risk of taking painkillers. to avoid painkillers39。side effects.【答案】 （1）D（2）C（3）B（4）C 【解析】【分析】本文是一篇說明文，根據(jù)《英國醫(yī)學(xué)雜志》的一項(xiàng)新研究，止痛藥正變成一種真正的疼痛。只服用一周就會(huì)使心臟病發(fā)作的風(fēng)險(xiǎn)增加50%。文章主要說明了止痛藥存在的風(fēng)險(xiǎn)，以及說明了其他一些可以有助于減輕疼痛的方法。研究還表明，只要你的心臟狀況良好，服用小劑量的藥物仍然是有效和安全的。 （1）考查推理判斷。根據(jù)第一段中的“The research suggested that the risk related to the use of certain drugs was greatest with higher doses (服用量) and during the first month of use.
