2020届人教版高考英语必修四课堂要点精析讲义:Unit2SectionⅠWarmingUp&Reading
Establishing a human colony on the Moon and travelling to Mars has been the stuff of dreams since the dawn of the space age. But these visions face many hurdles (障碍). How can humans survive for months or years in the ultrahostile (极端恶劣的) environment of space? What, for instance, will they eat? Agricultural researchers at a Dutch university say they are taking the first steps towards providing an answer. They are growing vegetables in soils similar to those found on the Moon and Mars, looking for ways of helping space pioneers grow their own crops. “When people go to the Moon and Mars they also have to eat, and it’s easiest for them to grow their own food,” said Wieger Wamelink, surrounded by several dozen plants in a special greenhouse at Wageningen, an agricultural university in central Netherlands. “We wanted to use real Martian and lunar soil, to see if plants would actually grow in it,” Wamelink told reporters. Of course, getting real lunar and Martian potting soil is an impossible task. But an Internet search revealed an unlikely supplier: NASA. “The US space agency makes ground similar to that on the Moon from sand found in an Arizona desert, while Mars’ crimson ’soil’ is scooped (舀;掏) from a volcano in Hawaii,” Wamelink told reporters. The first experiments started in 2013 after Wageningen received an order of 100 kilograms (220 pounds) of NASA’s imitation “space soil” — at a hefty price of 2,000 euros (D|S2,285). “To work in this soil was very special. Nobody, not even NASA, could tell us what would happen, even just by simply adding water,” he said. The imitation ground at first was a little “reluctant” to absorb water, but soon turned out to be good potting soil. “Especially in the Martian soil, plants were growing very fast and very good. They even started to flower, something that we never anticipated (预料,预见),” Wamelink said. Section_ⅠWarming Up & Reading — Prereading A PIONEER① FOR ALL PEOPLE Although he is one of China’s most famous scientists, Yuan Longping considers himself a farmer, for he works the land② to do his research. Indeed, his sunburnt③ face and arms and his slim, strong body are just like those of millions of Chinese farmers, ④for whom he has struggled⑤ for the past five decades⑥. Yuan Longping grows what is called super⑦ hybrid⑧ rice⑨. In 1973, he became the first agricultural pioneer in the world to grow rice⑩ that has a high output⑪. This special strain⑫ of rice makes it possible to produce 20% more of the crop⑬ in the same fields⑭. Now more than 60% of the rice produced in China⑮ each year is from this hybrid strain. Born in 1930, Yuan Longping graduated from Southwest Agricultural College in 1953. Since then, finding ways to grow more rice⑯ has been his life goal. As a young man, he saw the great need for increasing the rice output. At that time, hunger⑰ was a disturbing⑱ problem in many parts of the countryside. Yuan Longping searched for a way to increase rice harvests without expanding⑲ the area of the fields. In 1950, Chinese farmers could produce about fiftysix million tons of rice. In a recent harvest, however, nearly two hundred million tons of rice was produced. These increased harvests⑳ mean that 22% of the world’s people are fed from just 7% of the farmland in the world. Yuan Longping is now circulating his knowledge in India, Vietnam and many other less developed countries to increase their rice harvests. Thanks to his research, the UN has more tools in the battle to rid the world of hunger. Using his hybrid rice, farmers are producing harvests twice as large as before. ①pioneer n.开拓者;先锋;先驱 ②work the land耕种土地 work在此处意为“管理,经营,耕种”,是及物动词。 ③sunburnt/’sʌnbɜːnt/adj.晒黑的 ④for whom he has struggled=whom he has struggled for。 ⑤struggle/’strʌɡl/vi.&n.斗争;拼搏;努力 ⑥decade/’dekeId/n.十年;十年期 for the past five decades在过去的50年里,与现在完成时连用。 ⑦super/’sjuːpə/adj.特级的;超级的 常用来构成合成名词,如:supermarket“超市”,superman“超人”。 ⑧hybrid/’haIbrId/adj.混合的;杂种的 n.杂交种;混血儿 ⑨what is called super hybrid rice是what引导的宾语从句,what意为“……的东西;……的事情”。 ⑩动词不定式to grow rice作定语,修饰pioneer。 当词前有序数词或最高级修饰时,多用动词不定式而非分词短语作定语。 ⑪output/’aʊtpʊt/n.产量;输出(反义词:input) ⑫strain/streIn/n.(植物的)品种;种类 ⑬crop/krɒp/n.庄稼;农作物;产量 ⑭makes it possible是“make+宾语+宾补”结构,其中,it是形式宾语,真正的宾语是to produce 20% more of the crop in the same fields。 ⑮过去分词短语produced in China作后置定语,修饰rice。 ⑯动名词短语finding ways to grow more rice在句中作主语,动词不定式短语to grow more rice作定语,修饰ways。 ⑰hunger/’hʌŋɡə/n.饥饿;欲望 vt.&vi.(使)饥饿 have a strong hunger for sth.有得到某物的强烈欲望 ⑱disturbing/dI’stɜːbIŋ/adj.引起烦恼的;令人不安的 ⑲expand/Ik’spænd/vt.&vi.使变大;伸展 ⑳过去分词increased作定语,修饰harvests。 circulate/’sɜːkjʊleIt/vt.&vi.循环;流传 circulate knowledge传播知识 Vietnam/ˌvjet’næm/n.越南(东南亚国家) thanks to幸亏;由于;因为 battle/’bætl/n.战役;战斗;较量;斗争 vt.&vi.搏斗;奋斗 rid ...of使……摆脱或除去 rid/rId/vt.摆脱;除去 现在分词短语using his hybrid rice作原因状语。 twice as large as ……的两倍大 造福全人类的先驱 [第1~2段译文] 尽管他是中国最著名的科学家之一,袁隆平认为自己是个农民,因为他在田间耕作,进行科学研究。的确,他那被太阳晒得黝黑的脸庞和手臂,以及他那瘦削而又结实的身躯,就跟其他千百万中国农民一样。过去50年来,他一直在努力帮助他们。袁隆平种植的是被称为“超级杂交水稻”的稻种。1973年,他成为世界上第一位种植高产水稻的农业先驱。这种特殊的稻种使得同样的田地多收获20%的产量成为可能。如今中国每年生产的稻米有60%以上出自这种杂交稻种。 袁隆平于1930年出生,1953年毕业于西南农学院。从那时起,找到水稻高产的方法就成为他一生的目标。年轻时,他就看到了对水稻增产的巨大需求。当时,饥饿是许多农村地区面临的一个严重问题。袁隆平要在不增加土地面积的基础上寻求增加稻谷产量的途径。1950年,中国农民能生产大约五千六百万吨稻米,而近来却生产了将近两亿吨稻米。这一粮食产量的增加意味着中国仅用世界7%的耕地养活了世界22%的人口。袁隆平现在在印度、越南和很多其他欠发达国家传播提高水稻产量的知识。由于他的研究,联合国在消除世界饥饿的战斗中有了更多的方法。用他的杂交水稻种子,农民们种出的粮食比以前多了一倍。 Yuan Longping is quite satisfied with his life. However, he doesn’t care about being famous. He feels it gives him less freedom to do his research. He would much rather keep time for his hobbies. He enjoys listening to violin music, playing mahjong, swimming and reading. Spending money on himself or leading a comfortable life also means very little to him. Indeed, he believes that a person with too much money has more rather than fewer troubles. He therefore gives millions of yuan to equip others for their research in agriculture. Just dreaming for things, however, costs nothing. Long ago Yuan Longping had a dream about rice plants as tall as sorghum. Each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. He awoke from his dream with the hope of producing a kind of rice that could feed more people. Now, many years later, Yuan Longping has another dream: to export his rice so that it can be grown around the globe. One dream is not always enough, especially for a person who loves and cares for his people. be satisfied with对……感到满意 freedom/’friːdəm/n.自由;自主 would rather 宁愿;宁可 此处listening to ..., playing ..., swimming和reading均为enjoys的宾语。 动名词短语spending money ...在句中作主语,谓语动词mean用第三人称单数形式。 means very little to him对他来说意义不大 therefore/’ðeəfɔː/adv.因此;所以;因而 equip/I’kwIp/vt.&vi.配备;装备 sorghum/’sɔːɡəm/n.高粱 ear of rice稻穗 ear of corn 玉米穗 grain/ɡreIn/n.谷物;粮食;颗粒 peanut/’piːnʌt/n.花生 that could feed more people是that引导的定语从句,修饰a kind of rice。 export/Ik’spɔːt/vt.&vi.输出;出口 so that it can ...中,so that引导目的状语从句。 [第3~4段译文] 袁隆平很满意他的生活。但是,他对成名并不在意。他觉得出名后搞科研就不那么自由了。他宁愿把时间花在自己的业余爱好上。他喜欢听小提琴乐曲、搓麻将、游泳和读书。在自己身上花钱或者享受舒适的生活对他来说意义也不大。事实上,他认为一个人有了太多钱,他的麻烦事只会更多,而不是更少。于是,他拿出数百万元帮助其他人进行农业研究。 然而,梦想是不花本钱的。很久以前,袁隆平曾梦见水稻长得像高粱一样高,稻穗跟玉米穗一样大,而每粒稻米像花生米一般大。他从梦中醒来,希望能培育出一种能养活更多人的水稻。许多年后的今天,袁隆平还有另外一个梦想,那就是他的稻米可以出口以便长遍全球。一个梦想总是不够的,尤其对一个热爱和关心人民的人来说更是如此。 Prereading Please match the words with their proper meanings. 1.sunburnt A.to provide with things necessary for a certain purpose 2.decade B.extremely good 3.expand C.to try extremely hard to achieve something 4.therefore D.to remove sth.that is causing a problem from a place, group, etc 5.equip E.brown (skin) from spending too much time in the sun 6.export F.making you feel anxious and upset or shocked 7.rid G.to become larger in size, number or amount 8.super H.to send things to foreign countries for sale 9.disturbing I.as a result 10.struggle J.a period of ten years 11.statistic K.a job or profession 12.occupation L.a piece of information shown in numbers 1~5________ 6~10________ 11~12________ 答案:1~5 EJGIA 6~10 HDBFC 11~12 LK Leadin 1.What do you know about farming?

Even if you've only eaten half that much have to admit this: you've let some of that breakfast, lunch or dinner go to waste. And it turns out we're all to blame for this shaming fact: 30% of all food produced in the world each year is wasted or lost. That's about 1.3 billion tons, according to a new report by the U.N. Food and Agriculture Organization. That's the weight of more than 8.6 million fullgrown blue whales, the largest creatures on earth. That's the weight of more than 2.3 million Airbus A380s, the largest planes in existence. That's as if each person in China, the world's most populous country with more than 1.3 billion people, had one ton mass of food thrown into the dustbin. It's almost unfathomable,_isn't it? Setting aside that big number, we find the people with the most money are the ones who waste the most. On average, a person in European and North American countries wastes between 95 and 115 kilograms of food. SubSaharan African, South Asian and Southeast Asian countries waste much, much less — between 6 and 11 kilograms per person. Here's another statistic: all the food that the world's richest countries waste is about equal to all the food that subSaharan Africa produces. The numbers: 222 million tons and 230 million tons, respectively (分别地). Basically, the wasted food of the rich could feed much of the African continent. And these numbers come as we've just been reporting about rising food prices around the world in the past week. And my own personal tip: if I eat at a restaurant and can't finish it all, I ask for a doggie bag. I used to be a waiter years ago and will never forget the amounts of food I saw left on the table after the bill was paid. There's no reason to waste food. It's up to all of us to use our common sense to eat and shop just a bit more wisely. 语篇解读:本文为一篇说明文。根据联合国粮农组织的一份报告,目前全球生产出来的30%的食物在消费过程中被浪费。 1.What does the underlined word “unfathomable” in Paragraph 2 mean? A.Possible to imagine. B.Impossible to change. C.Impossible to understand. D.Possible to understand. 解析:选C 词义猜测题。根据第二段可知,每年浪费的食物的重量超过了860万头地球上最大的动物——蓝鲸的重量,也超过了230万架世界上现有的最大的飞机——空中客车A380的重量。这也好比在世界拥有超过13亿人的人口最多的国家——中国,人均向垃圾桶里倾倒一吨的食物。由此可推知这种现象使人难以理解。unfathomable意为“难以理解的;深不可测的”。 2.It can be learned that the food the rich waste can support ________. A.half the people in Europe B.most people of America C.most people of Asia D.most people of Africa 解析:选D 细节理解题。根据第四段倒数第二句“Basically, the wasted food of the rich could feed much of the African continent.”可推知,富有的国家浪费的食物可以养活非洲大陆大部分地区的人。 3.The author gave his personal tip based on the fact that ________. A.he was once very poor B.he was once a farmer C.he once worked in a restaurant D.the price of food is very high 解析:选C 细节理解题。根据最后一段第二句“I used to be a waiter years ago and will never forget the amounts of food I saw left on the table after the bill was paid.”可知,作者的建议是根据他曾是一个餐馆服务员的工作经历而给出的。 4.What is the purpose of this article? A.To show the author's opinion of food. B.To let us live more wisely and not waste food. C.To show the amount of wasted food a year. D.To ask the richest countries to help African people. 解析:选B 写作意图题。根据第一段倒数第二句“And it turns out we're all to blame for this shaming fact: 30% of all food produced in the world each year is wasted or lost.”和最后一段最后两句“There's no reason to waste food. It's up to all of us to use our common sense to eat and shop just a bit more wisely.”可推知,文章的写作目的在于让人们不要浪费食物,要更明智地生活。 B Looking for a few extra work hours or a new job?

In the Middle Ages it smelt particularly unpleasant due to its leather tanning (制革) industry. The nobility (贵族) only rarely visited the pretty and charming town to pick up their handmade and tanned leather gloves. Compared with the large area of land in the surrounding countryside, Grasse was certainly a necessary evil with no selfrespecting noble owning buildings there. Molinard, a Grasse tanner himself, created the first Grasse perfume. Word spread like wildfire amongst the nobility about the designer perfumed gloves. Molinard offered a pair of his gloves to Catherine de Medici (the Queen), who gave plenty of praise to her Grasse fragrant (芳香的) gloves; she almost singlehandedly assured Grasse's reputation as the perfume capital of the world. Thanks to Catherine de Medici, Grasse merchants were encouraged to grow the fragrant plants that tanners needed to supply perfumed leather to the nobility. Grasse has four perfume factories and perfumeries as well as a perfume school and a perfume museum. Fragonard's perfume museum is situated on the first floor of its perfume factory and displays an amazing private collection of perfume bottles, presentation boxes, documents and equipment that tell the history of perfume making from its earliest beginnings to the present day. The perfume museum is open every day, Sundays and public holidays included. Grasse is certainly a fragrant heaven, a_far_cry from its smelly beginning as a leather tanning town. Now famous for a far sweeter smell, Grasse is surrounded by fields of jasmine, roses and so on. Those looking for real estate in France would have to go a long way to find anywhere more charming than Grasse with the city of Nice and its airport just a short drive away and plenty of activities to enjoy in the surrounding countryside. Real estate in Grasse is situated between the Southern Alps and the Cote d'Azur, allowing owners the best of both worlds. 8. Why was Grasse considered to be necessary although it was an “evil”? A.It produced leather gloves. B.It was a beautiful and attractive town. C.It made the nobility look respectable. D.It beautified the surrounding countryside. 解析:选A 细节理解题。文章第一段中的“its leather tanning (制革) industry”“only rarely visited the pretty and charming town to pick up their handmade and tanned leather gloves”说明格拉斯当时制造的皮手套非常著名。故选A。 9.What does the underlined part “a far cry” in the last but one paragraph mean? A.A long cry. B.A great surprise. C.Very different. D.Very distant. 解析:选C 词义猜测题。画线词前后的“a fragrant heaven”和“from its smelly beginning as a leather tanning town”说明格拉斯现在是香水天堂,不同于它刚开始时是一个有皮革臭味的小城。 10.According to Para.3, Fragonard's perfume museum ________. A.has several perfume factories B.is famous for its perfume school C.shows visitors the history of Grasse D.can be visited all the year around 解析:选D 细节理解题。文章第三段的最后一句提到Fragonard香水博物馆每天(包括周日和公众假日)都对人们开放,因此选D项。 Ⅱ.阅读七选五 How to Make Friends with Neighbors Most people have neighbors where they live, whether it is in a house, a townhouse, or an apartment.
