高二英语外研版选择性必修第二册寒假作业 (9)Unit 3 Times change! 含解析
（9）Unit 3 Times change！——高二英语外研版寒假作业一、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 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 adaptation—not to air or to food, 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, they've also built houses 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 harvesting 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 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.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.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.Highlanders' Survival SkillsC.Basic Methods of Genetic ResearchD.The World's 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 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 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 weren't enough organic ingredients (原料), such as grain and cattle. This made it difficult for many 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 professionals 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 important 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 concern 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.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 ten 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."Myken 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 Myken's 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 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 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 isn't shining, or the wind isn't blowing.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 during 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 work 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 aneven 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 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 we're talking about 10,000 similar islands."1.Why is a hydrogen plant suitable for 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 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 the project?A.Promising.B.Systematic.C.Irreplaceable.D.Time-saving.4. It's lunchtime, and I'm 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 the counter interrupts me. "No cash, please!" says the cashier.These days, establishments that no longer accept cash have increased greatly. It's 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 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 Francisco's 2020 Diary of Consumer Payment Choice. What's more, because cash is 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 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?It's 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 affect those who are less likely to have access to noncash payment methods—namely 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 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 happened 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 cashless societies.D.To show the influence of cashless payments on people's 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. 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: ①_________Libraries meet students' new needs digitallyTo support modem research, libraries will need to offer students access to the digital 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. ②_________Flexible workspaces③_________ Most commonly, universities are redesigning libraries to make them suitable for collaboration(合作) —meaning 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-informed librariansIn today's university culture, librarians should make sure students have solid understanding of the digital resources they are using. ④_________ These and other changes are also influencing the way that universities teach the next generation of library professionals. At the University of Michigan, 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 power⑤_________ However, university libraries are here to stay. By using digital tools and creating flexible spaces, libraries will 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 example, 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.

命运的漩涡——《俄狄浦斯王》中的两次神谕班级：07汉文2班学号：312007********* 姓名：王梁宇索福克勒斯在《俄狄浦斯王》中为俄狄浦斯王设计的最后一句台词是这样的：“当你没有进入坟墓之前，你要说自己是幸福的，谁知道明天会发生什么。
”这就是命运！因为谁也说不准命运会在什么时候给人以迎头一击，西方有“上帝是个孩童”。
这样一种说法，而命运又何尝不是一个孩童呢？在《俄狄浦斯王》中这种命运的悲剧表现到了极致。
故事是从底比斯城的瘟疫开始，进而倒叙整个故事，底比斯城瘟疫就是俄狄浦斯悲剧命运的一个外显与爆发点，在没有瘟疫之前，一切都还是那么的风平浪静，但生活中往往就是这样，在平静的表象下往往潜藏着巨大的不安的分子，不是它们不存在，而只是你没有发现他们的存在，它们或许正在蓄势待发，准备给你以致命一击，它们正在等待这样一个机会，只要你一触及到它的机关，它就会如潘多拉的盒子一样打开来，什么坏的因子都窜了出来，唯独希望还被关在里面。
故事一开始就已经暗含了俄狄浦斯巨大的悲剧命运，而俄狄浦斯的悲剧也就随之浮出水面，犹如多米诺骨牌一样一步步拖着他走向命运万劫不复的深渊。
俄狄浦斯从最开始就已经跌进了命运的陷阱，早在他出生时，神谕就为他设计好了命运的牢笼，告诉他的父亲拉伊俄斯这孩子将来要弑父娶母，因此拉伊俄斯想把这个孩子处死，一个刚出世的孩子就得面对死亡，这本身就是一个悲剧。
但是如果他果真被处死，那么他所有的悲剧也就此结束，而事实绝对不可能也不会如此，命运也往往不会这么痛快，就如猫鼠游戏一样，因此俄狄浦斯在各种偶然因素（命运的安排）的影响下而免于被处死，成了科林斯国王的养子，似乎这一切都很平静，都在趋于常态，俄狄浦斯也本可以就此一生，但是命运却不会轻易放过一个悲剧的人，因而更大的悲剧命运也就会随之而来，神谕又一次充当了俄狄浦斯悲剧命运的设计师，让俄狄浦斯知道自己将来会弑父娶母。
到此，俄狄浦斯就完全沦为命运的傀儡，在命运的摆布下走向自己的悲剧深渊。
