答案:D
B
Two of the hardest things to accomplish in this world are to acquire wealth by honest effort and, having gained it, to learn how to use it properly. Recently I walked into the locker room of a rather well known golf club after finishing a round. It was in the late afternoon and most of the members had left for their homes. But a half dozen or so men past middle age were still seated at tables talking aimlessly and drinking more than was good for them. These same men can be found there day after day, and, strangely enough,each one of these men had been a man of affairs and wealth,successful in business and respected in the community. If material prosperity were the chief necessity for happiness, then each one should have been happy. Yet, it seemed to me, something very important was missing, or else there would not have been the constant effort to escape the realities of life through Scotch and soda.They knew, each one of them, that their productivity had ceased (停止). When a fruit tree ceases to bear its fruit, it is dying. And it is even so with man.

One of the main creators of the World Wide Web,Sir Tim Berners­Lee has warned that the fast growth of the Internet is also creating serious problems.He especially warns of false information being easily spread around the Internet,“A great danger is that it becomes a place where untruths start to spread more than truths,or it becomes a place which becomes increasingly unfair in some way.” In particular, he mentions the phenomena of blogging.Blogging enables friends and contacts to easily spread information.However, he argues that people may too easily trust information mentioned in a blog.This inaccurate information can then easily become an accepted truth on the Internet.He suggests that the most important development of the Internet will be in creating ways of allowing people to check the correctness of information by providing original sources.Sir Tim admits that this is an important challenge.It’s interesting to note that Wikipedia(维基百科) has had to take steps to prevent false i nformation from being added to the biographies of living people.It’s easy for anybody to edit the open source.However,some people have pointed out that it has been used to spread false materials.In seeking to raise standards,Wikipedia has sought to stop the false materials.At the same time there is a growing view that the Internet has had a great effect on the way millions of people work.The last two years have seen a big growth in the use of the Internet.There appears no slowdown in the growth of the Internet with increasing access in the developing countries.Sir Tim says another major challenge will be to provide free Internet for everybody.Sir Tim has recently launched a new joint initiative(倡议) between the University of Southampton and the Massachusetts Institute of Technology to create the first degree in Web science.The two schools hope to raise the standards of web content.【解题导语】本文是一篇说明文。

using poisonous cleaners.Throughout the month of April,Canadians are being asked to “Give It Up for Earth Day!” Earth Day has been cele brated every year on April 22 since 1970.Earth Day Canada’s president Jed Goldberg says that as people become more environmentally aware,they want to find ways to reduce their environmental influence,not just celebrate one special event.“Earth Day is a gr eat launching_pad for thinking about environmental action every day,” said Goldberg.“Choosing healthier options,even for the short term,can lead to thinking about the influence of our decisions for a lifetime.”That’s the reason behind the “Give It Up for Earth Day” campaign.It’s designed to encourage healthy habits that benefit people and the planet.It challenges everyone to help create a healthier world by making changes in their daily routine.“We wanted to plan an action­targeted campaign that will gi ve people a chance to act on their concern for the environment in a positive way,” said Goldberg.The campaign has identified four daily actions that can add up to huge environmental savings.They include pledging (保证) to turn off the TV,giving up the use of poisonous cleaners,reducing consumption of consumer products and cutting out meat.At the end of April,all of the pledges will be recorded and converted (转化) into the number of TV hours not watched,dollars not spent on unnecessary items,electricity saved,greenhouse gas emissions (排放) avoided by cutting out meat,and poisonous chemicals produced from homes and landfills.“What we’re trying to achieve this year for Earth Day is to give people a chance to do something that is meaningful and measurable,” said Goldberg.1.The aim of the campaign mentioned in the passage is to________.A.enable people to save more money for future useB.help people develop environmentally friendly habitsC.prevent people from making changes in their daily routineD.warn people against reducing consumption of consumer products2.The underlined part “launching pad” in Paragraph 3 probably means “________”.A.starting point B.finishing lineC.exchanging stage D.reforming age3.We can conclude from the passage that________.A.Earth Day was first celebrated over half a century agoB.short­term decisio ns will by no means influence our livesC.Earth Day Canada is actually an everyday environmental actionD.daily actions must be measured to benefit the environment4.Which disagrees with the spirit of “Give It Up for Earth Day”?A.Switching off the TV. B.Riding bikes.C.Using poisonous cleaners. D.Saving electricity.B(2014·四川省资阳市二模)So here’s the bad news for the 5.3 million New York City workers who depend on the subways to get from place to place:The entire system—all 1,050 km and 468 stations of it—is shut down,much of it flooded with corrosive (腐蚀性的) salt water.The Metropolitan Transit Authority (MTA) freely admits it has never faced anything like the severe damage from Hurricane Sandy,and has absolutely no idea when the system will be up and r unning.“We’ll know it after everything is done,” says MTA spokesman Charles Seaton.But the good news is—well,never mind.There isn’t any.Really,it’s that bad,and if there’s no telling when things will be repaired,there’s even less ways of knowing what the eventual price tag will be.Yes,there are lessons to be learned from the current emergency for both New York itself and urban planners everywhere;the question is whether they’ll be heeded.New York’s woes (难题) are partly a function.New York’s subway syst em is 108 years old.Its tunnels and stations are located close to or under rivers and harbors,and water seepage (渗水) is unavoidable.“We have three pump trains,300 pump rooms and dozens of portable pumps around the system,” says Seaton.“Even on a day when t here’s no rain,we pump out 13 million gallons of water.”Hurricane Sandy,of course,put a lot more stress on the system than an ordinary rainless day.Flood water in lower Manhattan rose to 4.2 m,beating the record of 3 m set by Hurricane Donna in 1960.Much of Manhattan below 40th St.is without electricity.No subway system will ever be truly immune to weather events.This is especially so in great cities like New York,whose very greatness in part depends on their nearness to rivers,harbors and other bodies of water.But spending money on the city’s basic transport system is perfectly possible,and indeed essential.That kind of preventive investment always seems too expensive at first,but only until you’re suddenly faced with the much higher repair bills New York is dealing with today.And as oceans continue to warm and sea levels continue to rise,the problem is only getting worse.In the past 20 years,Hurricanes Andrew,Floyd,Katrina,Rita,Dean,Irene,Isaac and others have tried to remind us of thatsimple truth.Now Hurricane Sandy is adding her voice.One of these days,we might actually listen.5.What can we infer from Para.1?A.The subway system may start running soon.B.The whole subway system is flooded with corrosive salt water.C.It is difficult to repair the New York subway system.D.The MTA doesn’t know how to clean the subway system.6.Before Hurricane Sandy,New York’s subway has long been troubled by________.A.corrosive salt water B.water seepageC.old pumps D.poor power systems7.In the last paragraph,which is mentioned as a threat to New York’s subway system?A.Climate change. B.The technical problem.C.Nearness to rivers. D.The high running cost.8.To solve the problem caused by weather events,the author suggests________.A.changing the subway’s locationB.building a new power systemC.making preventive investmentD.repairing the pumping systemⅤ.书面表达最近某高中开展以“校园杜绝零食”为主题的活动。

Unit 4 Global warmingⅠ.阅读理解A体裁:说明文话题:天气词数:303 时间:6′Droughts(干旱) caused by global climate change have led to a drop in wheat production,a worldwide shortage and high food prices around the world.The global wheat supply is at its lowest point in 50 years,with only an estimated 10 weeks of supply left.This has been one factor pushing the prices of bread,beer and other wheat-containing foods steadily higher.According to Hilton Dinner,a bakery owner from Edmonton,Canada,the price of flour has more than doubled over the past eight months.In 19 years of business,Dinner said,he has never seen prices rise like this.“Prices creep up seasonably,” he said.“They might go up 10 percent,then down 5 percent.They never go back to where they started,but they creep.This is not creeping,this is drastic.”Also to blame for the global wheat shortage is the rising population,coupled with increasing meat consumption worldwide.This has led to the increasing diversion of grain to animal feed.Analysts anticipate that the shortage may be resolved within 12 months,as farmers pull fallow land into wheat production.But even when the shortage resolves,food prices are only expected to keep climbing due to other factors,such as high energy and shipping costs.“It's not something that's going to go away,” Dinner said.“Food in general is going to go up.As wheat goes up,so does the price of eggs and chicken because they eat grain-based feed.It affects people who can't afford to pay more for their food.”Public health experts have expressed concern about the effect that rising food prices have on the poor.The United Nations recently reported that in 2007,the cost of food imports in the world's neediest countries increased 24 percent,to a total of $107 billion.【语篇解读】气候变化引起干旱,干旱又引起小麦产量的下降,产量下降又引起小麦价格的上涨。

(2018·贵州普通高中招生适应性考试)A record of 6.15 million trips was made by Chinese mainland tourists to overseas destinations during the seven­day Spring Festival holiday, which ended on Thursday, according to the China National Tourism Administration. That is an increase of 7 percent compared with last year’s Spring Festival. About 374,000 trips were organized by travel agencies, a 2.5 percent increase.The administration also reported growth from individual and high­end(高端的)travelers and said that in addition to top and coastal cities, inland cities—such as those in the Guangxi Zhuang Autonomous Region—became important source markets. With many Chinese now traveling abroad for Spring Festival, their choice of destinations has expanded along with their growing interest in foreign cultures and services.“Chinese tourists are increasingly willing to experience local cultures and services, including staying in private homes, appreciating plants and watching monkeys in hot springs,” Li Xuejing, the agency’s marketing manager, said.A Chinese tourist surnamed Guo, who was vacationing on an island in the Philippines, said:“I now pay more attention to relaxation and enjoyment during the holidays instead of shopping or choosing gifts for relati ves.”Another choice is Britain. Though the devaluation(货币贬值) of the pound is a factor, Britain’s rich history and famous education tradition have caught the eye of Chinese.【解题导语】本文是一篇新闻报道。

Everyone knows that death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two stages —clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have stopped functioning, but have not suffered permanent damage. The organism can still be saved. Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues. Death is then unchangeable and final.To show how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began taking blood out from an artery (动脉). The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta’s heart became active once more. After fifteen minutes, spontaneous (自发的) breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin (青霉素) injection, Keta seized the syringe (注射器)and ran with it around the room. Her behavior differed little from that of a healthy animal.1.For a person who suffers from the clinical death _________.A. he is still very much aliveB. he cannot avoid final deathC. his most important organs are damaged foreverD. he still has the possibility of getting back to life2.Scientists try to make the time of clinical death longer in order to _________.A. cool the organismB.C. slow down the body’s metabolismD. bring vital cells and tissues back to active life3.The text mainly talks about _________.A. clinical death and biological deathB.an experiment on a monkeyC. the meaning of deathD. the process before death4.From the underlined sentence in the last paragraph we can know that _________.A. Keta was impoliteB. Keta was healthyC. Keta was illD. Keta was crazy【文章大意】本文主要叙述了为了延缓生理死亡的到来,科学家尽量延长临床死亡的时间。

Unit 4 Global warming Ⅰ.阅读理解 A Dear Alcohol, You've been around forever. I can remember all the pain you've caused me. Do you remember the night when you almost took my father's life? I do. He loves you. Sometimes I think he loves you more than he loves me. He's addicted to you and to the way you promise to rid him of his problems only to cause more of them. You just sat back and laughed as his car went turning through the street, crashing into two other cars. He wasn't the only one badly hurt by you that night. Do you remember the night of my first high school party? My friends were intrigued by you. They treated you as if they were never going to see you again, drinking all of you that they could. I spent two hours that night helping my friends who had fallen head over heels for you. “I'm so embarrassed,” they said as I held their hair back so that they could throw up. “I'm sorry,” they said when I called taxis for them, walking them out and paying the driver in advance. “This won't happen again,” they said as they were sent to the hospital to have their stomachs pumped. Two 15­year­old girls slept in hospital beds that night due to you. Do you remember the night when you took advantage of my 17­year­old neighbor who had to drive to pick up his sister from her dance lessons? Do you know how we all felt when he hit another car head­on and killed two people in the other car? He died the next morning too. His sister walked home from her dance lesson, and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. She didn't realize her brother was among them at all. She never saw him again. And it was all your fault. I wish you'd walk out of my life forever. I don't want anything to do with you. Look at all the pain you've caused. Sure, you've made people happy too from time to time. But the damage you've caused in the lives of millions is not excusable. Stop attracting the people I love! Stop hurting me, please. Sincerely, Me [语篇解读] 这篇文章是一封书信。作者用拟人化的手法,写信给酒,痛斥它给人们带来的伤害,以此劝诫人们远离酒。 1.What did Alcohol do to the author's father that night? A.It made him drunken and took his life away.

Recently I walked into the locker room of a rather well­known golf club after finishing a round. It was in the late afternoon and most of the members had left for their homes. But a half­dozen or so men past middle age were still seated at tables talking aimlessly and drinking more than was good for them. These same men can be found there day after day, and, strangely enough,each one of these men had been a man of affairs and wealth,successful in business and respected in the community. If material prosperity were the chief necessity for happiness, then each one should have been happy. Yet, it seemed to me, something very important was missing, or else there would not have been the constant effort to escape the realities of life through Scotch and soda.They knew, each one of them, that their productivity had ceased (停止). When a fruit tree ceases to bear its fruit, it is dying. And it is even so with man. What is the answer to a long and happy existence in this world of ours? I think I found it long ago in a passage from the book of Genesis which caught my eye while I was looking through my Bible.The words were few, but they became memorably impressed in my mind:“In the sweat of the face shall you eat the bread.”
