课时跟踪练17 Unit 2 Working the land Ⅰ.阅读理解 A Have you ever heard of agritourism where you can experience farm life? If not, Dr Cindy AyersElliott will tell you the real story of Foot Print Farms.‎ The original idea of building Foot Print Farms was simple.When AyersElliott returned to her hometown after graduation, she didn't have to look any further than her state's alarming health statistics to find a mission.Everywhere she turned, there were reports of high blood pressure,diabetes,obesity and heart disease.“The problem was already identified,” explains AyersElliott.“Too many Mississippians were seriously unhealthy and it didn't take research to see that.And many of the state's greatest health challenges could directly result from poor diet.”‎ These days, Foot Print Farms, which started with a few raised beds of herbs and vegetables, is making fresh, naturally grown food.“When speaking of the key to my success, the coop model works because we share the work and rewards,” notes AyersElliott.“A perfect example is the Wingfield High School football team.To earn the money for equipment and other items, players committed to working five hours a week on the farm, and by the end of the summer they had produced 1,000 melons and the profits from their sales helped to buy weights, Tshits, sweat suits and pregame meals. But the lessons they learned about the rewards of hard work and working together to accomplish something were even more valuable products of their efforts.”‎ ‎“It's a model that can easily be learned in other places and I'm looking forward to seeing some of our current partners do just that-to take what they have learned here and spin it off in other communities,” AyersElliot remarks.She is now looking forward to developing an agritourism aspect to the farm, where visitors can experience farm life, learn new skills and take with them seeds of inspiration they can sow in their own communities when they return home.‎ ‎1.What made AyersElliott set up Foot Print Farms?‎ A.The problems faced by local farmers.‎ B.Her further research into heart disease.‎ C.The failure of her career after graduation.‎ D.The health state of people in her hometown.‎ - 8 -‎ ‎2.Why does AyersElliott take the football team as an example?‎ A.To advocate the concept of independence.‎ B.To stress the importance of teamwork.‎ C.To support the idea of coop model.‎ D.To explore the key to success.‎ ‎3.What is AyersElliott's attitude toward the future of Foot Print Farms?‎ A.Optimistic.     B.Skeptical.‎ C.Cautious. D.Ambiguous.‎ ‎【语篇解读】 针对自己家乡人们的身体状况出现的诸多问题,如肥胖症、高血压等,艾尔斯-埃利奥特创建了自己的农场,目的是让游客体验农场生活,学些新技能,回归健康生活。‎ ‎1.解析:细节理解题。根据第二段中的“...she didn't have to look any further than her state's alarming health statistics to find a mission.Everywhere she turned,there were reports of high blood pressure, diabetes,obesity and heart disease.”可知,艾尔斯-埃利奥特在家乡的报道中看到了很多有关高血压、糖尿病、肥胖症和心脏病的问题,而正是由于这一情况,她建立了自己的农场。故选D项。‎ 答案:D ‎2.解析:推理判断题。根据第三段中的“‘When speaking of the key to my success,the coop model works because we share the work and rewards,’notes AyersElliott.‘A perfect example is the wingfield High School football team.’”可知,艾尔斯-埃利奥特借用温菲尔高中足球队的例子说明成功的关键是合作,进而论证自己的观点。故选C项。‎ 答案:C ‎3.解析:推理判断题。根据最后一段中的“‘It's a model that can easily be learned in other places...She is now looking forward to developing an agritourism aspect to the farm...”可知,艾尔斯-埃利奥特认为这一模式便于效仿学习,而且她期望在农场中发展农业旅游。由此可推知,她对农场的未来充满信心。故选A项。‎ 答案:A B Many of us love summer because it's the season when vegetables are in abundance.Fresh vegetables have almost all of the nutrients that our body requires.‎ Fresh cabbage is an excellent source of natural vitamin C.It also contains an adequate number of minerals.Sweet carrot is notably rich in antioxidants (抗氧化物), vitamins and dietary fiber.Onion is a rich source of chromium (铬), a mineral - 8 -‎ ‎ that helps cells respond appropriately to insulin (胰岛素) levels in the blood.As for me, tomato, juicy and delicious, is a wonderful gift to the world.Besides, it contains very good levels of vitamin A and vitamin C, and antioxidants, which are scientifically found to be protective against cancers.‎ Eat at least 5—7 servings of fresh vegetables every day.Seasonal vegetables should be encouraged.Whenever possible, go for organic farm vegetables to get maximum health benefits.Organic ones tend to be smaller but have rich flavor, possess some good concentration of vitamins and minerals and are loaded with numerous health benefiting antioxidants.‎ After shopping your choice of vegetables, the first thing you need to do is to wash them thoroughly, especially leafy green vegetables. Soak in salt water for a few minutes, and gently wash in cool water until you are satisfied with the cleanliness.This way you insure they are free from dirt sand and any chemical sprays.If you need to store them, then place inside plastic wrappings in order to preserve their nutrition for short periods until you use them.However, the best way is to use them early while fresh because, firstly, certain vegetables have very short period life and secondly, the heath benefiting qualities of a vegetable decline with time.‎ ‎4.What does the author seem to like about tomatoes?‎ A.They contain chromium.‎ B.They are high in minerals.‎ C.They have a pleasant taste.‎ D.They can control insulin levels.‎ ‎5.Which of the followings is not the advantage of organic farm vegetables?‎ A.Having more vitamins and minerals.‎ B.Containing more antioxidants.‎ C.Having smaller size.‎ D.Being delicious.‎ ‎6.Which is the best choice about choosing vegetables?‎ A.Fresh and nutritious vegetables.‎ B.Delicious and bigger vegetables.‎ C.Juicy and smaller vegetables.‎ D.Seasonal and organic vegetables.‎ ‎7.From which is the text probably taken?‎ A.A biology textbook.‎ - 8 -‎ B.A health magazine.‎ C.A research paper.‎ D.A travel brochure.‎ ‎【语篇解读】 夏季的蔬菜不仅新鲜,而且营养丰富。本文介绍了卷心菜、胡萝卜及洋葱等蔬菜所包含的营养元素,当然,想要保持健康,除了了解蔬菜的营养成分之外,科学的饮食方法也十分重要。‎ ‎4.解析:细节理解题。根据第二段中的“As for me,tomato, juicy and delicious,is a wonderful gift to the world.”可知,作者喜欢西红柿的美味。故选C项。‎ 答案:C ‎5.解析:细节理解题。根据第三段中的“Organic ones tend to be smaller but have rich flavor,possess some good concentration of vitamins and minerals and are loaded with numerous health benefiting antioxidants.”可知,有机蔬菜的优势是味美、富含维生素和矿物质及抗氧化物,大小不是其优势。故选C项。‎ 答案:C ‎6.解析:细节理解题。根据第三段中的“Seasonal vegetables should be encouraged.Whenever possible,go for organic farm vegetables...”可知,选择蔬菜要重点考虑“应季”和“有机”这两个因素,故选D项。‎ 答案:D ‎7.解析:推理判断题。本文开头说明夏季的蔬菜新鲜、富有营养且多种多样,接下来又介绍了富有营养的若干蔬菜及科学的食用方法,由此可知,本文的话题是健康饮食,所以文章应该选自“健康杂志”。故选B项。‎ 答案:B Ⅱ.七选五 People worldwide are living longer.Today, most people can expect to live into their sixties and beyond.By 2050, the world's population aged 60 and older is expected to total 21 billion, up from 901 million in 2015.‎ While this shift in the proportion (比例) of a country's population toward older ages—known as aging—started in high income countries.For example, in Japan, 30% of the population are already over 60 years old.It is now lowand middleincome countries that are experiencing the greatest change. 1 ‎ At the biological level, aging results from molecular (分子的) and cellular damage over time.This leads to a growing risk of disease and death eventually. 2 That's why we say there is no “typical” older person.While some 70yearolds enjoy extremely good health, other 70yearolds are weak and require a lot of help from - 8 -‎ ‎ others.‎ ‎ 3 Retirement, relocation and the death of friends and partners are some of the possible reasons.For example, moving older people to a better house, which seems admirable behaviour, may do harm to their health eventually.‎ ‎ 4 Some people believe older people can be active and productive. A longer life brings opportunities, both for older people themselves and for society.They can pursue new activities such as further education or a new career.They also contribute in many ways to communities. 5 This can lead to discrimination against older people.Therefore, society as a whole needs to address the ageist attitude by developing sound policies and offering various opportunities so that older people can experience fulfilling aging.‎ A.Nobody can ever escape from the aging process.‎ B.But these changes are only loosely linked to a person's age.‎ C.Yet the extent of their contribution depends heavily on their health.‎ D.Beyond biological changes, aging is also related to other life changes.‎ E.Although aging is a universal trend, views toward older people is different.‎ F.However, to others, older people are weak, dependent, and a burden to society.‎ G.By 2050, many countries like Chile and China will have a similar rate of older people to Japan.‎ ‎【语篇解读】 本文介绍了世界人口老龄化问题,以及人们对于人口老龄化的不同看法。‎ ‎1.解析:根据上文内容可知,人口老龄化现象起源于高收入国家,但是目前中低收入的国家也正经历此次转变。G项“By 2050,many countries like Chile and China will have a similar rate of older people to Japan.”(截至2050年,许多像智利和中国这样的国家也会有和日本相似比例的老年人)承接上文,符合语境。故选G项。‎ 答案:G ‎2.解析:空后讲到这就是为什么我们说没有典型的老年人的原因。一些70岁的人身体非常好,而另一些70岁的人身体却很虚弱,需要别人的很多帮助。B项“But these changes are only loosely linked to a person's age.”(但是这些变化与一个人的年龄没有太大的关系)中的changes指代上文中的随着时间的推移所产生的分子损伤和细胞损伤,语义上引出下文,过渡自然,符合语境。故选B项。‎ 答案:B ‎3.解析:设空处位于段首,有对本段内容进行总结的作用。D项“Beyond biological - 8 -‎ ‎ changes,aging is also related to other life changes.”(除了生理变化,老龄化与其他生活变化也有关系)符合语境;另外,D项中的Beyond biological changes也对应了第三段第一句中的At the biological level(在生物层面上),承上启下。故选D项。‎ 答案:D ‎4.解析:设空处位于段首,有对本段内容进行总结的作用。本段内容主要讲述了人们对于老年人的不同态度。E项“Although aging is a universal trend,views toward older people divide.”[虽然老龄化是一个全球的趋势,但是(不同的人)对于老年人的看法是不同的]符合语境。故选E项。‎ 答案:E ‎5.解析:本段主要讲述了人们对老年人的不同态度,空前是一些人的正面看法,故本空应是另一些人的反面看法。F项“However,to others,older people are weak,dependent,and a burden to society.”(但是,对于另一些人来说,老年人是虚弱的,有依赖性的,是社会的负担)符合语境。故选F项。‎ 答案:F Ⅲ.语法填空 Chinese researchers have 1. (successful) grown and harvested rice in the deserts of Dubai (迪拜) after developing a strain (品种)which 2. (allow) the crop to grow in salt water.‎ A team of scientists, 3. (lead) by China's “father of hybrid rice”, Yuan Longping, have already started growing the crop in diluted (稀释了的) seawater at home and are now bringing the technique to the Middle East.‎ The big harvest of rice last year in the suburbs of Dubai far exceeded scientists' expectations, according to a report by Xinhua News Agency. The high output—7,500 kilograms per hectare (公顷) compared with the 4. (globe) average of 3,000 kilograms per hectare has encouraged scientists to expand the project.They 5. ‎ ‎(plan) to set up a 100hectare experimental farm in Dubai later last year.They will put it into regular use this year and then start expanding after 2020.‎ The Dubai project is a cooperation between China's Sea Rice Research and Development Centre with the private office of Sheikh Ahmed bin Saeed AlMaktoum.The two parties have signed an 6. ‎ ‎(agree) to promote seawater rice across the Arab world to reduce the risk of food shortages in the future.‎ While scientists in some countries 7. water shortages are a serious concern have been developing desalination (脱盐) techniques to change seawater for use in ‎ - 8 -‎ agriculture, China has been working ‎ ‎8. (develop) strains of saltresistant rice for the past four decades.‎ Although 9. is not yet clear how the Dubai project will be able to secure enough fresh water to dilute seawater 10. ‎ largescale rice planting, Chinese scientists have already started growing it closer to home on a commercial scale.‎ ‎【语篇解读】 中国“杂交水稻之父”袁隆平带领的一支科学家小组,开始在国内用稀释的海水种植水稻,并把这一技术带到了中东地区。最近在迪拜沙漠中成功地收获了水稻。‎ ‎1.解析:考查词性转换。句意为:中国研究人员已经成功培育出了一种能在海水中生长的水稻品种,并且已经在迪拜的沙漠中种植,收获了(水稻)。此处作状语修饰动词短语grown and harvested,应用副词。故填successfully。‎ 答案:successfully ‎2.解析:考查动词的时态及主谓一致。句意见上一题解析。which引导定语从句,指代a strain,且在从句中作主语,谓语动词应用第三人称单数形式。介绍这一水稻品种能在海水中生长的事实特征,应用一般现在时。故填allows。‎ 答案:allows ‎3.解析:考查非谓语动词。句意为:由中国“杂交水稻之父”袁隆平领导的一个科学家小组已经开始在国内用稀释的海水种植这种农作物,而且现在正将这种技术带往中东地区。本句谓语是have started和are bringing,故此处应用非谓语动词。又因为A team of scientists和lead之间为逻辑上的被动关系,故用其过去分词形式。故填led。‎ 答案:led ‎4.解析:考查词性转换。句意为:与全球平均每公顷产3 000千克相比,这种每公顷产量高达7 500千克的水稻已经激励了科学家们扩大这一项目。空前有定冠词the,空后average是名词,应用形容词修饰。故填global。‎ 答案:global ‎5.解析:考查动词的时态。句意为:去年科学家们计划以后在迪拜建立一个100公顷的实验田。根据时间状语last year可知,设空处应用一般过去时。故填planned。‎ 答案:planned ‎6.解析:考查词性转换。句意为:这两支团队的当事人已经签署了一项协议,以促进阿拉伯地区的海水水稻种植,从而减少未来粮食短缺的风险。前有不定冠词an,应用名词。故填agreement。‎ 答案:agreement ‎7.解析:考查定语从句。句意为:当一些淡水资源严重缺乏的国家的科学家们一直在研究脱盐技术,试图把海水改变成淡水以供应农业使用时,中国在过去40‎ - 8 -‎ 年一直致力于抗盐水稻品种的研究。设空处引导定语从句,且在从句中作地点状语,先行词是countries,指地点,应用关系副词where。故填where。‎ 答案:where ‎8.解析:考查非谓语动词。句意见上一题解析。本句谓语是has been working,故develop应用非谓语动词形式,此处表目的,应用不定式短语作目的状语。故填to develop。‎ 答案:to develop ‎9.解析:考查代词。句意为:虽然现在仍不清楚迪拜项目将如何保证足够的淡水去稀释海水,以供大规模的水稻种植,但中国科学家们已经开始在国内大规模商业化种植了。此处应用it作形式主语。故填it。‎ 答案:it ‎10.解析:考查介词。句意见上一题解析。名词性短语largescale rice planting是dilute seawater的目的,表示“目的”时介词应用for。故填for。‎ 答案:for - 8 -‎
