1、（9）Unit 3 Times change！2021-2022学年高二英语外研版（2019）寒假作业一、阅读理解1. We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopi

2、an highlands have adapted to living at high altitudes. Cattle-raising people in East Africa and northern Europe have gained a mutation(突变) that helps them digest milk as adults. On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptationnot to air or to food,

3、 but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, theyve also built h

4、ouses on stilts (支柱) in coastal waters. They are simply a stranger to the land, said Rodney C. Jubilado, a University of Hawaii researcher who studies the Bajau. Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harves

5、ting shellfish. We were so amazed that they could stay underwater much longer than us local islanders, Dr. Jubilado said. I could see them actually walking under the sea. In 2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered

6、 if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. It seemed like the perfect chance for natural selection to act on a population, said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.1.

7、What does the author want to tell us by the examples in Paragraph 1 ?A.Environmental adaptation of cattle raisers.B.New knowledge of human evolution.C.Recent findings of human origin.D.Significance of food selection.2.Where do the Bajau build their houses?A.In valleys.B.Near rivers.C.On the beach.D.

8、Off the coast.3.Why was the young Jubilado astonished at the Bajau?A.They could walk on stilts all day.B.They had a superb way of fishing.C.They could stay long underwater.D.They lived on both land and water.4.What can be a suitable title for the text?A.Bodies Remodeled for a Life at SeaB.Highlander

9、s Survival SkillsC.Basic Methods of Genetic ResearchD.The Worlds Best Divers2. Organic food is very popular. It is also expensive. Some organic food costs twice as much as non-organic food, but new parents and pet owners are willing to pay up to 200% more for organic food. However, there are people

10、who think it is a waste of money. There is one main difference between organic and non-organic food. Organic farms do not use agricultural chemicals, such as pesticides. In many countries organic foods have special labels. These guarantee that the products are natural.Some people think organic means

11、 locally grown. Originally this was true. Over time organic farming became more difficult. The demand for organic food grew larger than the supply. Small companies had to sell out to large companies. There werent enough organic ingredients (原料), such as grain and cattle. This made it difficult for m

12、any organic companies to stay in business. Today, many large companies have an organic line of products. Is organic food more nutritious? This is part of the debate. Many farmers and consumers believe it is. They think agricultural chemicals cause health problems such as cancer. Many health professi

13、onals disagree. Few studies prove that organic foods prevent health problems. Health specialists worry more about bacteria (病毒), such as E.coli and salmonella. These can get into contact with organic and non-organic food. Doctors recommend washing produce very carefully. Handling meat carefully is i

14、mportant too. Most people agree that naturally grown food tastes better. Is tastier food worth the extra money? This is a matter of opinion. Whether it is healthier or not may require more research. However, organic consumers argue it is better to be safe than sorry.1.What is probably the major conc

15、ern of organic food consumers?A.Freshness.B.Price.C.Safety.D.Variety.2.What is the doctors suggestion?A.Grow your own food.B.Reduce the use of pesticides.C.Buy large companies products.D.Make sure the food is clean.3.Which of the following do most people agree on organic food?A.It is more nutritious

16、.B.It is easier to grow.C.It contains more fat.D.It tastes better.4.Where does this text probably come from?A.A recipe book.B.A health magazine.C.A medical report.D.A chemistry paper.3. Surrounded by the sea off the coast in Mid-Norway, there is an island called Myken. This small island has about te

17、n permanent residents, and for more than 50 years has been supplied with electricity via a 32-kilometre undersea cable (电缆). A break that appeared in the cable last autumn resulted in two months without power, so the island community started looking into a better way of sourcing their electricity. M

18、yken is far out at sea, so as far as possible it should be taking care of things itself, says Trude Tokle, who is the project manager of Mykens energy project. This is why we want Myken to become entirely self-sufficient in energy. It is also important to take the environment into consideration, she

19、 says. Many point to the idea that the solution may lie in a hydrogen(氢) plant, specifically tailored for small islands. The raw materials for hydrogen production come from nature itself in the form of the sun and wind. Researchers have calculated that energy costs will be lower by using hydrogen pr

20、oduction than the undersea cable option. And it is possible to store energy in the form of hydrogen for longer periods. This means that supplies will not have to rely on a lot of expensive batteries or external energy sources, even during periods when the sun isnt shining, or the wind isnt blowing.

21、The Myken project has attracted several technology companies. They are currently working on a pilot project. The project involves experiments on the feasibility(可行性) of the hydrogen system in which electricity is generated from solar and wind sources. The electricity can be used immediately, but dur

22、ing periods when all the energy generated is not required, the spare energy can be used to split seawater into hydrogen and oxygen. The hydrogen can be stored in a tank, and used later to generate electricity. The pilot project will help researchers know more about how effectively the system will wo

23、rk in the hydrogen plant. Since the island has a distillery(酿酒厂), where the distillation (蒸溜) process relies on energy, a hydrogen plant on Myken offers an even greater environmental benefit. Spare heat from the hydrogen system can also be used for the heating part in the distillation process. In No

24、rway alone there are about 300 islands inhabited all year round by small populations, says Kyrre Sundseth, a hydrogen researcher in Norway. All of these islands may be candidates for using this technology. In global terms were talking about 10,000 similar islands.1.Why is a hydrogen plant suitable f

25、or Myken?A.It is perfect in size for small islands.B.It can send electricity to faraway places.C.It will restore local natural environment.D.It provides green and sustainable energy.2.What is mainly talked about in Paragraph 4?A.The study on the energy storage.B.The test on the hydrogen system.C.The

26、 experiment on the raw materials.D.The research on the innovation of the pilot project.3.According to the passage, a hydrogen plant will _.A.produce purified seawaterB.prove more effective workC.contribute in more than one wayD.benefit from the distillation process4.What does Kyrre Sundseth think of

27、 the project?A.Promising.B.Systematic.C.Irreplaceable.D.Time-saving.4. Its lunchtime, and Im eager to try a new establishment that opened near our office in midtown Manhattan. I walk to the shiny new storefront, place my order and make my way to the counter(柜台) to pay. As I dig into my wallet and st

28、art to pull out some cash, the person behind the counter interrupts me. No cash, please! says the cashier. These days, establishments that no longer accept cash have increased greatly. Its long been said that cash is king, but the tendency could be turning in the US. While cash continues to be the m

29、ost common payment method among consumers, its usage is declining. The use of cash in 2019 dropped by 3 percentage points to 30 percent of all transactions(交易) in just two years, according to the Federal Reserve Bank of San Franciscos 2020 Diary of Consumer Payment Choice. Whats more, because cash i

30、s most likely to be used in small transactions ($ 10 or less), it accounted for only 9 percent of the total payment value in the same year. The use of cards, at the same time, has held steady, and mobile payments have begun to grow. Nearly cashless societies are already a reality outside the US. In

31、Sweden, cash accounts for only 2 percent of the value of all payments, and total cash in circulation accounts for just 1 percent of Swedish GDP. China, meanwhile, leads the way in mobile payments, recording more than $ 20 trillion in 2019. But should a cashless future be accepted enthusiastically? I

32、ts true that not handling cash could allow for an increase in speed and efficiency(效率). Cashless payments, however, have their downside. We might start to see a rise in cybercrimes(网络犯罪), while a cashless society could decrease physical crimes. Critics argue that cashless establishments unfairly aff

33、ect those who are less likely to have access to noncash payment methodsnamely the unbanked/underbanked. According to the Pew Research Center, those in households earning less than $ 30,000 per year are more likely to use cash than those with higher incomes. A cashless society, no doubt, has its adva

34、ntages, but it can also bring a host of new challenges.1.What problem does the author have at lunchtime?A.He loses his way.B.He forgets to bring cash.C.He fails to have his lunch.D.He is asked not to pay in cash.2.What can we learn about the use of cash in the US in 2019?A.It saw a fall.B.It only ha

35、ppened in small transactions.C.It accounted for 3% of all its transactions.D.It was less frequent than the use of mobile payments.3.Why does the author mention Sweden and China?A.To list the benefits of cashless payments.B.To voice his doubt about cashless societies.C.To show the global spread of ca

36、shless societies.D.To show the influence of cashless payments on peoples life.4.What is one reason why the author is against a cashless society?A.It is inconvenient for small transactions.B.It puts some people at a disadvantage.C.It puts the underbanked in danger.D.It encourages physical crimes.二、七选

37、五5. In higher education, 21st-century librarians are seeing their roles changing. University library buildings are also taking a new look. However, one thing is clear: _Libraries meet students new needs digitally To support modem research, libraries will need to offer students access to the digital

38、versions of scholarly research. Ringling College of Art and Design set out to create a library that would better provide its students with the services they actually need. _Flexible workspaces_ Most commonly, universities are redesigning libraries to make them suitable for collaboration(合作) meaning

39、open, social spaces where small and large groups can gather and share materials. For example, Norwich University in Vermont decided to create more high-tech collaboration spaces in its library by designing 11 group study rooms that have movable furniture. Modern libraries need digitally well-informe

40、d librarians In todays university culture, librarians should make sure students have solid understanding of the digital resources they are using. _ These and other changes are also influencing the way that universities teach the next generation of library professionals. At the University of Michigan

41、, a new library science program will create education models that help future librarians complete the difficult tasks of supporting researchers.Digital tools give libraries staying power_ However, university libraries are here to stay. By using digital tools and creating flexible spaces, libraries w

42、ill continue to be relevant to colleges. In fact, digital tools have made it even easier for libraries to serve students.A.University libraries are here to stay.B.Librarians are going to lose their occupations.C.Libraries are disappearing in this technology age.D.One must-have characteristic, for ex

43、ample, was a 24-hour computer lab.E.For example, librarians can help students get reliable information better.F.Some people predicted that the next generation would witness the death of printed books.G.Changing study habits also give libraries an opportunity to redesign their physical spaces.三、完形填空6

Many people find new emojis an exciting way of communicating. They expand upon the way we communicate.

50、 Emojis, by design, make a direct link between written communication and the real world, by using pictures or icons that represent ideas or emotions. They are accessible, so we also dont _(necessary) substitute (代替) an English word for an emoji when we read a text (contain) one. So then how should w

51、e consider emojis collectively? Are they a language, when they _ (use) only in writing? You can send someone anentire message _ (compose) of emojis. But you probably cant use emojis by _ (they) as a self-contained way of communicating with people without sooner or later turning to English or another

82、ck hole, Barry broke out in a cold sweat. He might have run into the house like the badly injured driver had it not for the old mans kind reminder. He thanked the old man millions of times. As they parted, the old man gently squeezed Barry on the shoulder and said softly, Young man, learn to slow do

83、wn and a host of carelessaccidents can be avoided. Absolutely, I will keep that in mind.Barry nodded heavily as he turned away. Back to the office, Barry threw himself into his armchair, deep in thought. The old mans words kept ringing in his ears, which he felt made a huge sense. In fact, so quick-

84、paced was he that Barry hardly noticed the No Speeding sign on the roadside, in which case he might have crashed into the same hole and knocked the house down, whose ruins would swallow his car as a whole and bury him alive. At the thought of this, Barry felt the familiar cold sweat returned. Slow down. He jotted down the two words on his note sticker and put it up where he could see it easily.
