1、高考英语主旨大意练习 班级 考号 姓名 总分 ARodney Smith is a man with a task.The Bermuda native is in the midst of a trip that will take him to every state in the nation, mowing lawns（修理草坪）.Five years ago, Smith came across a senior man mowing his lawn and stopped to help.“When I came across the elderly man, my life c

2、hanged,” he saiD.After that, Smith went on to create the Raising Men Lawn Care Service (RMLCS) to mow lawns for the elderly, disabled, single moms and former soldiers free of charge.As part of providing free yard work, the organization teaches children about serving their communities and lawn mower

3、safety.A key component of RMLCS is its 50-yard challenge, which sets a goal for children nationwide to mow 50 lawns for free in their community.When a kid signs up for the challenge, the group sends them a white shirt with the Raising Men logo（标识），shades and ear protection.The participants receive a

4、 different colored shirt after every 10th lawn they mow.When they have completed the task for 50 yards, they receive a special visit from Smith or someone with RMLCS.They give the volunteer a new lawnmower, free of charge, and cut other lawns with them.Since this challenge started in 2016, 12 kids h

5、ave already completed the challenge.And both boys and girls are part of it.At present they have 130 kids nationwide taking part in this challenge, including7 inBermuda and the U.K.and one in Canada.So its spreading worldwide.Even the Queen of England took notice the governor of Bermuda presented Smi

6、th with an award late last year on behalf of her.It was also last year that Smith came up with the 50 States 50 Lawns campaign.Now, in 2020，hes on the road again.1.What is the purpose of the Raising Men Lawn Care Service?A.Educate children to work harD.B.Offer free lawn cutting service.C.Make lawnmo

7、wers of high quality.D.Train professional lawn mowing workers.2 Why is the Queen of England mentioned?A.To praise the queen for her care.B.To prove Smith is respected by everyone.C.To show Smiths behavior got recognizeD.D.To introduce where Smiths motivation came from.3.What can be the best title fo

8、r the text?A.Mow Lawns in Order to TravelB.Lawn Mowing a New TrendC.Choose Mowing Lawns to HelpD.Smith a Man Loves Mowing LawnsBAdolescent chimpanzees adopt their younger siblings (兄弟姐妹) if their mothers die.The older siblings keep a close watch on the youngsters and give them lots of comforting hug

9、s.The finding adds to the evidence that chimpanzees can understand when others are suffering and can, to some extent, help them.Similarly, a second study has shown that chimpanzees have a strong emotional response when they see that another chimp or a familiar human is injureD.Rachna Reddy and John

10、Mitani at the University of Michigan were tracking a group of about 200 chimps in Kibale National Park, Uganda, when a deadly disease struck the animals between December 2016 and February 2017.Twenty-five chimps died and 13 lost their mothers.Reddy and Mitani kept a close watch on four pairs of youn

11、g chimpanzee siblings, where the older of the two effectively adopted the younger.The older chimps were 10-17 years old while the younger siblings were 6 to 7 years olD.The pairs spent much more time together after their mothers deaths than they did before.They also comforted each other.It was like

12、they were both seeking physical contact all the time, says Reddy.The behavior makes evolutionary sense, because by helping their siblings, the older chimps are acting in the interest of their own genes. We cant be sure what is going through their minds, but Reddy says the younger siblings were clear

13、ly scared and upset and the older siblings seemed to take the situation seriously.I am hesitant to use a word like responsibility, says Reddy, but she says they were responding to their siblings suffering.In line withthis, chimps react when one of their members is injured: they may inspect or help d

14、eal with a wound, for instance.Yutaro Sato at Kyoto University in Japan and his colleagues have now found that chimps respond on an emotional level to seeing an injury.They showed six chimps a human with whom they were familiar, and who had a serious wounD.The cameras showed a temperature drop insid

15、e the chimps noses, which is known to have links with a strong negative emotion.4.Why did the older chimpanzees adopt the younger siblings?A.Because they enjoyed having playmates.B.Because they observed the law of jungle.C.Because they were taught to take responsibility.D.Because they understood the

16、ir siblings suffering.5.What is the purpose of paragraph 3?A.To show how they conducted the research.B.To make an analysis of the findings.C.To compare the two researches.D.To describe a moving story in the research.6.What does the underlined word this refer to?A.Chimps unwillingness to help.B.Chimp

17、s minds full of sadness.C.Chimps reaction to their siblings suffering.D.The decrease of chimps nose temperature.7.Which is the best title for the text?A.Chimps really do careB.The mystery of chimpsC.Chimps: to be or not to beD.The power of evolutionCWood has many great characteristics that make it t

18、he perfect building material.It is cheap，durable(耐用的),easily available，and most importantly，environmentally sustainable.The one thing it is not, is transparent(透明的).Now thanks to a team of scientists at Stockholms KTH Royal Institute of Technology，the material may even be able to addthat featureto i

19、ts already impressive list.Lead researcher Dr.Lars Berglund said he was inspired to create the transparent wood after learning how Japanese researchers had developed a see-through paper for use in flexible display screens for electronic devices.The team began by pulling out the woods lignin(木质素).The

20、 lignin-free wood was then dipped into a polymer(聚合物)and baked at a temperature of 158F for four hours.The result was a hybrid product that was not only stronger and lighter than the original wood but also，almost transparent.The researchers were able to adjust the level of transparency by varying th

21、e amount of the polymer injected and also by changing the thickness of the wooD.While scientists have previously created a see-through wood for small-scale applications like computer chips, he transparent wood is the first one being considered for large scale applications.The researchers, who reveal

22、ed their findings in Biomacromolecules on April 11, picture using the transparent wood in buildings to allow for more natural light, or to create windows that let in the desired amount of light without sacrificing privacy.Wood that allows light to pass through could lead to a brighter future for hom

23、es and buildings.Berglund also thinks the wood could play a significant role in the design of solar panels.The semi-transparent material would be able to keep light longer and give it more time to interact with the conductor, thus resulting in better solar efficiency.Additionally, substituting the c

24、urrently used glass with this new product would help solar energy manufacturers improve their carbon footprint and lower the cost.They are now experimenting with ways to scale up the manufacturing process so that the transparent material is cost-effective to make and easy to use.8.What does the unde

25、rlined part “that feature” in Paragraph 1 refer to?A.Cheapness.B.Durability.C.Sustainability.D.Transparency.9.Which of the following is not the process in which the transparent wood is made?A.Dip the wood into a polymer.B.Reduce the amount of the polymer.C.Make the wood lignin-free.D.Bake the wood f

26、or some time.10.Which of the following is true according to the text?A.Berglund got the idea of transparent wood while making paper.B.Varying the amount of the polymer changes the woods hardness.C.The cost of making the transparent wood still needs to be cut down.D.The transparent wood would be used

27、 only for homes and buildings.11.What is the last paragraph mainly about？A.The bright future of the transparent wooD.B.The woods role in the design of solar panels.C.The disadvantages of the currently used glass.D.Solar energy manufacturers carbon footprint.DDolphins, African gray parrots and some o

28、ther animals understand the idea of “zero,” but researchers were surprised to find that honeybees also comprehend this abstract concept, considering the insects tiny brains, according to a new study.Honeybees have fewer than one million neurons(神经元), compared with the 86 billion neurons in humansand

29、 yet, they grasp a concept that humans, by some measures, dont start to understand before preschool.The researchers set up two cards, each of which had a set of symbols on them, like triangles or circles.Then, they trained a group of the bees to fly to the card with the lower number of symbols.The b

30、ees quickly learned what the humans wanted them to do to get their delicious, sweet rewards.The trained bees were then shown a card that was empty and one that had symbols on it.There is no need for the bees to be trained to fly more often to the empty cardthus showing that they understood that “zer

31、o” was a number less than the others.Although they flew more often to an empty card than to one that had one symbol on it, it became easier for them to distinguish when the symbols on the card increased in number.For example, they more often flew to the zero when the other card had four symbols than

32、 when it had one.Perhaps these findings will explain the brain mechanism(机制)behind what allows us to understand the concept of “nothing,” Adrian Dyer, a researcher saiD.This understanding, in turn, could help in the development of artificial intelligence (AI) that also understands this concept.“If b

33、ees can understand zero with a brain of less than a million neurons, it suggests there are simple, efficient ways to teach AI new tricks,” Dyer said in the statement.12.What is a surprising finding for the researchers?A.Many animals also comprehend the meaning of “zero”.B.The number of neurons of ho

34、neybees is much smaller.C.Honeybees can understand “zero” with their tiny brains.D.Humans fail to recognize abstract ideas before preschool.13.What can the bees do without further training?A.Fly directly to the card with more symbols on it.B.Fly less often to the card with fewer symbols on it.C.Fly

35、quite slowly to the card without anything on it.D.Fly more often to the card without any symbol on it.14.What does Adrian Dyer say about these findings?A.They offer inspiration to the development of technology.B.They enable people to understand more abstract concepts.C.They suggest ways to teach hum

36、ans some complex tricks.D.They allow people to set a new type of brain mechanism.15.What is the main idea of the text?A.Honeybees know about the concept of “zero”.B.Honeybees can understand much as humans do.C.Honeybees will help to improve AI in the future.D.Honeybees can be trained to comprehend “

37、zero”.附：参考答案A【答案】B【解析】推理判断题。根据第二段“Smith went on to create the Raising Men Lawn Care Service (RMLCS) to mow lawns for the elderly, disabled, single moms and former soldiers free of charge.”可知，史密斯创办RMLCS是为了给老人，残疾人，单亲妈妈和退役军人免费修理草坪。故选B。【答案】C【解析】细节理解题。根据第四段“Even the Queen of England took notice the gover

38、nor of Bermuda presented Smith with an award late last year on behalf of her.”可知，甚至英国女皇都知道史密斯，并派总督代表她给史密斯颁奖。故选C。【答案】C【解析】主旨大意题。全篇叙述了史密斯为特定人员免费修理草坪，并且为全国孩子设立目标：为自己的家园免费修理50码的草坪。这一系列的举动，都是和修理草坪相关，是一种助人的行为。故选C。B【答案】D【解析】理解题干，迅速定位到文本第二段第一句话“The finding adds to the evidence that chimpanzees can understan

39、d when others are suffering and can, to some extent, help them.”由此判断选D项。【答案】A【解析】读懂第三段主要介绍观察对象、过程和结果，即如何具体实施研究，故选A项；第四段介绍了科学家的分析，因此把干扰项B排除；文章介绍了两个实验，第三段中没有进行比较，因此选项C排除；文章是说明文体裁，没有进行故事描写，排除D项。故选A项。【答案】C【解析】理解第三段最后一句话中的“they were responding to their siblings suffering”；理解第四段第一句话“In line withthis, chim

40、ps react when one of their members is injured”，（与之一致，当猩猩看到同伴受伤时，会做出反应）；“this”就是指代第四段中的最后一句话。故选C项。【答案】A【解析】A选项“猩猩的确关爱”。本文通过两个实验发现猩猩在同伴或亲属痛苦受伤时表现出关爱，故选择A选项；B选项“猩猩的神秘”，表述太笼统，与本文主题不相关，故排除；C选项“猩猩，生存还是毁灭”，与本文主题不相关，故排除；D选项“进化的力量”，太笼统，与本文主题不相关，故排除。C【答案】D【解析】词义猜测题。根据第一段中的“It is cheap，durable(耐用的)，easily avai

41、lable，and most importantly，environmentally sustainable.The one thing it is not，is transparent(透明的)”可知，木头便宜，耐用，容易获得，最重要的是，可持续。但是它不是透明的。而最后一句提到：由于科学家的努力，已经将“那个特点”添加到已有的特点单子里了。根据这个语境可以推知，该处应指，科学家们使得木头成为透明的了。“透明”也成为了它的一个特点。故该画线词应该指D选项：透明。【答案】B【解析】细节理解题。根据第二段中的“The lignin-free wood was then dipped into a

42、 polymer(聚合物)and baked at a temperature of 158F for four hours”可知，制造透明木头的过程之一是：将无木质素的木材浸泡在聚合物中，在158华氏度的温度下烘烤4小时。因此B选项提到的“减少聚合物的量”和原文不符。故B选项切题。【答案】C【解析】推理判断题。根据最后一段中的“They are now experimenting with ways to scale up the manufacturing process so that the transparent material is cost-effective to make

43、and easy to use”可知，现在，他们正在尝试扩大制造工艺，使得透明材料制造起来更加合算，易于使用。由此推知，现在制造透明木头的成本仍然很高，需要降低成本。故C选项正确。【答案】A【解析】主旨大意题。最后一段介绍了透明木头将来在家庭，建筑物，太阳能电池板，环保等方面的应用。由此可知，最后一段主要介绍了透明木头的光明未来。故A选项正确。D【答案】C【解析】细节理解题。根据第一段“.but researchers were surprised to find that honeybees also comprehend this abstract concept, considering

44、 the insects tiny brains.”可知，令研究人员惊奇的是蜜蜂的脑容量小，但它们却也能理解像“零”这样的抽象概念。故C选项正确。【答案】D【解析】细节理解题。根据第二段的内容，尤其是最后一句可知，蜜蜂能飞向没有符号的卡片是不需要被进一步训练的。故D选项正确。【答案】A【解析】推理判断题。根据最后一段“If bees can understand zero with a brain of less than a million neurons, it suggests there are simple, efficient ways to teach AI new tricks.Dyer said in the statement.”可知，Adrian Dyer认为这些发现能够为科技的发展提供一些灵感。故A选项正确。【答案】A【解析】主旨大意题。通读全文可知，本文主要是在讲蜜蜂与其他许多动物一样，能理解诸如“零”这样的抽象概念。故A选项正确。7
