In the UK, one in every 10 young people aged 5 to 19, is obese. Obese children are likely to become obese adults, posting them at risk ofP1 serious health problems, say experts. Researchers believe wide availabilityW2 of cheap, fattening food is one of the main drivers. Although child obesity rates appear to be stable in many high­income European countries, including the UK, they are increasing at an alarming rateP2 in many other parts of the world. The largest increase in the number of obese children has been in East Asia. China and India have seen rates “balloon” in recent years. Polynesia and Micronesia have the highest rate of all—around half of the young population in these countries is overweight or obese. The researchers say that if current world trends continue, “obese” will soon be more common than “underweight”. “We have not become more weak­willed, lazy or greedy. The reality is that the world around us is changing.” Dr Fiona Bull from the World Health Organization suggested tough measures to prevent “calorie­rich, nutrient­poor food” and encourage more physical activity. “But so far, just over 20 countries around the world have introduced a tax on sugary drinks，” she said. Dr Alison Tedstone, chief nutritionist (营养学家) at Public Health England, said, “Our sugar reduction programme and the government's sugar tax are world­leading, but this is just the beginning of a long journey to meet the challenge of a generation. The evidence is clear that just telling people what to do won't work. While education and information are important, deeper actions are needed to help us lower calorie consumptionW3 and achieve healthier diets.” 篇章导读：本文是一篇说明文。全球的儿童肥胖问题严重，这些肥胖儿童在长大成人后很可能还带有肥胖症，面临严重的健康问题。为了解决这个问题，各国采取了许多措施，但仍是一个漫长的旅程。 1．What mainly contributes to child obesity according to the researchers? A．Children are driven to consume cheap diets. B．Children don't take enough physical exercise. C．Children become more weak­willed and greedy. D．Children can reach cheap and fattening food more easily. 答案：D　细节理解题。根据第一段最后一句“Researchers believe wide availability of cheap, fattening food is one of the main drivers.”可知，儿童可以更容易得到廉价和容易发胖的食物是儿童肥胖的主要原因。故选D。 2．How can we describe child obesity rates in France? A．Slow. B．Alarming. C.Steady. D.Ballooning. 答案：C　推理判断题。根据第二段第一句“Although child obesity rates ... in many other parts of the world.(尽管在包括英国在内的许多高收入欧洲国家，儿童肥胖率似乎保持稳定，但在世界其他许多地区，儿童肥胖率正以惊人的速度增长。)”可推知，法国是高收入的欧洲国家之一，所以在法国儿童肥胖率是稳定的。故选C。 3．What may Dr Fiona Bull think of the sugar tax? A．It is perfect. B．It needs to be promoted further. C．It is not effective enough. D．It should be made to be less tougher. 答案：B　推理判断题。根据第四段最后一句“‘But so far, just over 20 countries around the world have introduced a tax on sugary drinks，’ she said.(‘但到目前为止，世界上只有20多个国家对含糖饮料征税，’她说。)”可推知，Dr Fiona Bull(菲奥娜·布尔医生)认为需要进一步推广糖税。故选B。 4．What can be inferred from the last paragraph? A．England is the first to tax sugary drinks. B．Solving the problem of child obesity is a hard nut. C．Education plays a small role in controlling child obesity. D．People should be told about the danger of being overweight. 答案：B　推理判断题。根据最后一段中的“The evidence is clear that ... deeper actions are needed to help us lower calorie consumption and achieve healthier diets.(有证据表明，仅仅告诉人们该做什么是行不通的。虽然教育和信息很重要，但需要更深入的行动来帮助我们降低卡路里摄入量，实现更健康的饮食。)”可推知，解决儿童肥胖问题是一件棘手的事情。故选B。 W重点单词 1．trend n. 趋势 2．availability n. 有效，可使用性 3．consumption n. 消耗 P重点短语 1.at risk of 冒……危险 2．at an alarming rate 以惊人的速度 Ⅲ　语法填空 Senior citizens are the first to come to our mind when it comes to hearing loss, __1__ in a recent report, hearing professionals worry teenagers will soon outnumber aging adults. The rise in __2__ (popular) of personal audio devices from iPods to smart phones has had dangerous effect on the ears of those who use them most, teenagers! A research __3__ (conduct) by the World Health Organization finds that nearly 50% of teens __4__ (fall) into the habit of exposing themselves to unsafe levels of sound so far. A sound is considered unsafe when it goes beyond 85 decibels (分贝). At that level, it takes just 8 hours of listening over your lifetime to cause damage. The louder the sound is, the __5__ (little) time it takes. Because hearing loss is __6__ (typical) considered a health problem for the elderly, it's difficult to convince already stubborn teenagers of the damage to their ears. Young adults who __7__ (expose) to loud noise over a period of time may have some hearing loss symptoms. Their ability to learn is compromised, and they may have difficulty developing social skills. __8__ an effort to help teens better protect their hearing, we suggest __9__ (set) volume limits on personal audio devices. It is also good to limit the amount of time exposed to noise and to take listening breaks to give the ears __10__ rest. 1．________　2.________　3.________　4.________ 5．________　 6.________　7.________　8.________ 9．________　10.________ 篇章导读：本文是一篇说明文。最近一项报告显示，听力专家担心青少年将会在听力损失方面超过老年人，这是iPods或智能手机等所带来的负面影响。 1．but　考查连词。设空前后语义表示转折，故填but。 2．popularity　考查词性转换。设空前为冠词in，后为介词of，所以设空处缺少名词，故填popularity。 3．conducted　考查非谓语动词。conduct和逻辑主语research是被动关系，应用过去分词作状语。故填conducted。 4．have fallen　考查动词的时态和主谓一致。根据时间状语so far可知，句子应用现在完成时；主语50% of teens为复数，故填have fallen。 5．less　考查形容词的比较级。固定句型the＋比较级 ...，the＋比较级 ... 意为“越……，越……”，故填less。 6．typically　考查词性转换。应用副词修饰动词，故填typically。 7．have been exposed　考查动词的时态和语态。根据设空后over a period of time可知，应用完成时，全文为现在时态，应用现在完成时；定语从句中，先行词Young adults和expose之间为被动关系，应用现在完成时的被动语态。故填have been exposed。 8．In　考查介词。in an effort to意为“企图做某事，努力做某事”；句首首字母大写，故填In。 9．setting　考查非谓语动词。句意：为了帮助青少年更好地保护他们的听力，我们建议对个人音频装备设置音量限制。固定用法suggest doing sth意为“建议做某事”，故填setting。 10．a　考查冠词。give ... a rest意为“让……休息一下”。故填a。 学科网（北京）股份有限公司 $$
