1、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 Ethiopian highlands have adapted to living at high alt
2、itudes. 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, but to the ocean. A group of sea-dwelling peop
3、le 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 houses on stilts (支柱) in coastal waters. They ar
4、e 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 harvesting shellfish. We were so amazed that they cou
5、ld 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 if centuries of diving could have led to the e
6、volution 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.What does the author want to tell us by the exa

9、earchD.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 who think it is a waste of money. There is one
10、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 locally grown. Originally this was true. Over
11、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 many organic companies to stay in business. Toda
12、y, 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 professionals disagree. Few studies prove that organic
13、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 important too. Most people agree that naturally
14、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 concern of organic food consumers?A.Freshness.B.Pri
15、ce.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.B.It is easier to grow.C.It contains more fat.
16、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 ten permanent residents, and for more than 50 yea
17、rs 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. Myken is far out at sea, so as far as possible i
18、t 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 says. Many point to the idea that the solution
19、 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 production than the undersea cable option. And it
20、 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. The Myken project has attracted several technol
21、ogy 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 during periods when all the energy generated is no
22、t 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 work in the hydrogen plant. Since the island has
23、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 Norway alone there are about 300 islands inhabite
24、d 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 for Myken?A.It is perfect in size for small isla
25、nds.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 experiment on the raw materials.D.The research
26、 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 the project?A.Promising.B.Systematic.C.Irrepla
27、ceable.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 start to pull out some cash, the person behind th
28、e 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 most common payment method among consumers, its
29、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 is most likely to be used in small transactions
30、($ 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 Sweden, cash accounts for only 2 percent of the
31、 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? Its true that not handling cash could allow for
32、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 affect those who are less likely to have access to
33、 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 advantages, but it can also bring a host of new cha

35、 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 cashless societies.D.To show the influence of cas
36、hless 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、七选五5.
