Unit 2 Food and Health Reading 主题阅读 夯实基础 Recently,Venetia Berry, an artist in London, counted up the free cotton bags in her house. There were at least 25. She got these cotton bags from CT eco-fashion brands,art shops,hotels,and even an apple farm. "You get them without choosing,"said Berry. Cotton bags have become a way for brands,shops and supermarkets to show that they care about the overuse of plastic bags in packaging(包装). There was a short stop in using cotton bags during the pandemic when there were fears that reusable bags could carry and spread the virus, but they are now fully back in force. So far, so earth-friendly? Not exactly. It turns out the popularity of cotton bags may actually have created new problems. The production of cotton needs lots of water. And dealing with cotton bags in an environmentally friendly way is far from as simple as people think. You can't, for example, just put a cotton bag in a dustbin. Even when a cotton bag does make it to a special treatment plant(处理工厂)，most dyes(染料)used to print pictures on them are PVC- based and cannot be recycled. Printed pictures have to be cut out of the cloth. About 10 to 15 percent of the cotton is wasted this way. That's not to say cotton is worse than plastic. Cotton may use pesticides(杀虫剂) and has dried up rivers from water consumption,but making plastic bags will produce much greenhouse gas and pollute the land and rivers. A clothing company stopped production of its cotton bags in April this year. Some brands are turning to other ways. However, the simplest way may be the clearest—not every product needs a bag. 1.Venetia Berry is mentioned in Paragraph 1 to show______. A. the fame of the artist B. the popularity of cotton bags C. the way people get cotton bags D. the reason why cotton bags are popular 2.Why do many companies use cotton bags? A. They believe cotton bags are friendly to the environment. B. They want to follow the new fashion of cotton bags. C. They think plastic bags are not convenient. D. They think plastic bags can spread the virus. 3.What does Paragraph 3 mainly talk about? A. The overuse of cotton bags. B. The importance of special treatment plants. C. The waste produced by cotton bags. D. The troubles caused by using cotton bags. 4.What does the underlined word“ consumption in Paragraph 4probably mean in Chinese? A.浪费 B.污染C.消耗 D. 蒸发 5.The writer·probably advises us to______. A.try to use bags less if possible B. use cotton bags as often as possible C.use bags made of other materials D. stop using cotton bags completely 语篇解读 为了解决塑料包装袋过度使用这一问题，许多商家选择给顾客提供棉布袋。但是棉布袋并不像想象中的那样环保，它们的使用也带来了一些问题。 答案详析 1.B推理判断题。根据第一段的内容可知，Venetia Berry的家里有至少25个棉布袋，这些棉布袋来自各种商家。由此可推知，棉布袋被广泛使用，故第一段提到Venetia Berry的例子是为了体现棉布袋很流行。 2.A细节理解题。根据第二段第一句“Cotton bags have become a way for brands,shops and supermarkets to show that they care about the overuse of plastic bags in packaging.”可知，棉布袋已经成了许多商家表示他们关注塑料包装袋过度使用这一问题的一种方式。由此可知，许多公司使用棉布袋是因为他们认为棉布袋更环保。 3.D段落大意题。通读第三段可知，本段主要介绍了棉布袋的使用所带来的问题，如耗水、处理过程较为复杂等。故D项正确。 4.C词义猜测题。根据第三段中的“The production of cotton needs lots of water.”可知，棉花的生产需要大量的水；再根据画线词前的has dried up rivers可推知，生产棉花需要水源，因而导致了河流干涸，故推测consumption意为“消耗”。 5.A 推理判断题。根据文章最后一句“However, the simplest way may be the clearest—not every product needs a bag.”可知，作者认为最简单的方法可能是最显而易见的——并不是每个产品都需要袋子。故推测作者建议我们尽量少用袋子。 提升能力 A woman who couldn't feel hungry after a stroke(中风) may help us improve our understanding of one area of the brain. The 28-year-old Canadian was hospitalized after feeling weak on one side of her body and having trouble speaking. The examination result showed that she had a stroke in a brain area called the insula(脑岛). Soon after the stroke.the woman noticed that she never felt hungry any more, even when she hadn't eaten for a long time. She often forgot to eat and lost more than 10 kilograms. The woman could still taste and smell the food, but often ate about half as much as usual because she no longer enjoyed eating. Even chocolate,her favorite food,gave her no pleasure. The woman's hunger finally came back about 12 months after the stroke. The insula is one of the least understood parts of the brain. It works with other parts of the brain to make a feeling of hunger that encourages eating. “This woman's brain would still have been receiving signals（信号)that she was missing calories, but because of the damage(损伤) to her insula, she wouldn't have been aware of them," says Yoav Livneh at the Weizmann Institute of Science in Israel. This finding could help to find new ways to treat obesity(肥胖).For example, it may be possible to use some ways to send signals to the insula to prevent overeating,Livneh says. He agrees that this is a possibility,but says it will be more important not to damage the insula's other functions(功能). 1.Why did the woman eat less just after the stroke? A. She was in a bad mood. B.She was trying to lose weight. C. She was advised to eat less. D. She lost the ability to feel hungry .2.What happened to the woman a year after the stroke? A.She often forgot something. B.She couldn't taste the food. C. She lost interest in chocolate. D. She could feel hungry again. 3.What can we know about the insula? A. It is easy to be damaged after a stroke. B. It is the most important part of the brain. C. It tells us when we should eat something. D.It makes stroke patients difficult to smell. 4.What will the new finding probably help us to do? A. Fight against the stroke. B. Make our brain stronger. C. Go on a healthy diet. D. Deal with the obesity problem. 5.What's the best title for the passage? A. New Treatment on Stroke B. Insula's Newly-Found Role C. Secrets to Fight Obesity D. Some Research on the Brain 语篇解读 一位女士在中风后一年的时间里都没有饥饿感，这是因为她大脑中的脑岛遭到了破坏。这起病例或许可以帮助我们找到治疗肥胖的新方法。 答案详析 1.D 细节理解题。根据第一段中的“A woman who couldn't feel hungry after a stroke”以及第三段中的“Soon after the stroke, the woman noticed that she never felt hungry any more even when she hadn't eaten for a long time.'可知，这位女十吃的比原来少了。是因为她中风后无法感觉到饥饿。 2.D 细节理解题。根据第四段最后一句“The woman's hunger finally came back about 12 months after the stroke.”可知.在中风12个月之后，她的饥饿感又恢复了。 3.C推理判断题。根据倒数第二段第二句“It works with other parts of the brain to make a feeling of hunger that encourages eating."可知，脑岛与大脑的其他部分一起工作来产生饥饿感，从而刺激人们去吃东西。 4.D 细节理解题。根据最后一段第一句“This finding could help to find new ways to treat obesity.”可知，这个新发现可能会帮助我们找到治疗肥胖的新方法，故D项正确。 5.B 主旨大意题。通读全文可知，一位女士在中风后失去了饥饿感,检查结果显示这是因为她大脑中的脑岛受到了损伤。研究人员认为这一发现可能有助于找到治疗肥胖的新方法。故B项“脑岛的新‘角色’”最适合作文章标题。 原创精品资源学科网独家享有版权，侵权必究！2 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$ Unit 2 Food and Health Reading 主题阅读 夯实基础 Recently,Venetia Berry, an artist in London, counted up the free cotton bags in her house.
