I. GrammarPlease mind the silenceDespite being used by 1.34 billion people each year, traveling on the Tube in London can actually be quite lonely. An unwritten rule encouraging silence, mixed with classic British reserve, means that ________ ________ you’re packed into an enclosed space with hundreds of other people, the morning commute (上下班) can leave you feeling somewhat isolated.One London resident, however, is trying to change this.“You get on the Tube here and ifs completely silent and ifs weird," says Jonathan Dunne, 42, an American living in London, who has, ironically, started _________ worldwide dialogue after giving out badges (徽章) with the slogan “Tube chat?” last month, encouraging commuters in London to get talking to one another. “I handed out 500 badges during rush hour in a city of 8 million, expecting many refusals and most of them _________ (throw) away, but after about 24 hours it completely snowballed,” he says.Dunne and his “Tube chat” campaign ________(feature) in media across the world ever since, seeing TV interviews in Sweden, Brazil and the UK, as well as countless website, newspaper and magazine appearances.Although Dunne says he’s received mostly positive feedback, not everyone agrees with his sentiment. Londoner Brian Wilson responded with a campaign of ________ own, handing out 500 badges with the word s ‘‘Don’t even think about it” on them.“I ________ hardly stand the idea of having to talk to strangers on the Tube on my way to work,” he told the BBC. Michael Robinson, 24, a student from London, agrees. “Being on the Tube is the only peace and quiet s ome people get on their journeys to and ________work. It doesn’t need to be spoiled by people coming up and chatting to you,” he says. While London has its seemingly antisocial set of regulations to follow, not everywhere lacks a sense of community.Does Dunne hope that some of this community spirit ______ ____(mirror) in the UK following his campaign? “People assume that I just walk up and talk to strangers, ________ I don’t, but it’s been a great way to meet people you would never have normally spoken to,” he says.“On Monday, Oct 10, the curator (馆长) of the London Transport Museum had me over for tea.”So if you ever end up ________ (use) public transport in the West, why not say hello to the person next to you? Just make sure to check for a badge first.II. VocabularyThe rise in stories describing events that never happened, often involving fake people in fake places, has led to Facebook and Google’s _______ to deal with them. But are we really so easy to fool? According to several studies, the answer is yes: even the most obvious fake news starts to become believable if it’s _______ enough times.In the months running up to the US election there was a surge(大浪) in fake news. Accordingto an analysis by Craig Silverman, a journalist, during this time the top 20 fake stories in circulation________ the top 20 stories from 19 mainstream publishers.Paul Horner, a creative publisher of fake news, has said he believes Donald Trump was elected because of him. “My sites were picked up by Trump supporters all the time… His followers don’t fact-check anything –they’ll post everything, believe anything,” he told the Washington Post.Silverman previously ________ rumours circulating online in 2014 and found that shares and social interactions around fake news articles dwarfed(使...相形见绌) those of the articles that exposed them. According to Silverman, fake news stories are engineered to appeal to people’s hopes and fears, and aren’t ________ by reality, which gives them the edge in creating shareable content.You might think y ou’re immune to falling for these lies, but a wealth of research disagrees. Back in the 1940s, researchers found that “the more a rumour is told, the more ________ it sounds”. They suggested this means that a rumour born out of mild suspicion can, by gaining currency, shift public thinking and opinion.This false impression of truth was ________ practically in 1977 when researchers in the US quizzed college students on the actuality of statements that they were told may be true or false. The researchers found that simply repeating the statements at a later date was enough to increase the ________ of the students believing them.Last year, Lisa Fazio at Vanderbilt University in Tennessee and her team found that students become more likely to believe a statement that they know must be false if it is repeated.“Our research suggests that false news can and likely does affect people’s _______. Even ifpeople are conscious that a headline is false, reading it multiple times will make it seem more trustworthy,” Fazio says.Reassuringly, the team found that a person’s knowledge still has a large influence over their beliefs, but it’s still a worrying ________ given that falsehoods appear repeatedly in our newsfeeds every day.III.ClozeTwo key climate change indicators — global surface temperatures and Arctic sea ice extent —have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite data. Each of the first six months of 2016 set a record as the warmest ________ month globally in the modern temperature record, which ______1880, according to scientists at NASA's Goddard Institute for Space Studies (GISS) in New York. The six-month period from January to June was also the planet's warmest half-year on record, with a(n) ________ temperature 1.3 degrees Celsius (2.4 degrees Fahrenheit) warmer than the late nineteenth century.Five of the first six months of 2016 also _______ the smallest respective monthly Arctic sea ice _______ since regular satellite records began in 1979, according to analyses developed by scientists at NASA's Goddard Space Flight Center, in Greenbelt, Maryland. The one _____, March, recorded the second smallest for that month.______ these two key climate indicators have broken records in 2016, NASA scientists said it is more significant that global temperature and Arctic sea ice are continuing their decades-long trends of change. Both trends are ultimately driven by rising _______ of heat-trapping carbon dioxide and other greenhouse gases in the atmosphere.The extent of Arctic sea ice at the peak of the summer melt season now typically ______ 40 percent less area than it did in the late 1970s and early 1980s. Arctic sea ice extent in September, the seasonal low point in the annual cycle, has been _______ at a rate of 13.4 percent per decade."While the El Niño event in the tropical Pacific this winter _______ the gaining global temperatures from October, it is the basic trend which is producing these record numbers," GISS Director Gavin Schmidt said.______ El Niño events have driven temperatures to what were then record levels, such as in 1998. But in 2016, even as the effects of the recent El Niño wear off, global temperatures have risenwell beyond those of 18 years ago _______ the overall warming that has taken place in that time.The global trend in rising temperatures falls behind the regional _____ in the Arctic, said Walt Meier, a sea ice scientist at NASA Goddard."It has been a record year so far for global temperatures, but the record high temperatures in the Arctic over the past six months have been even more extreme," Meier said. "This warmth as well as unusual weather ______ have led to the record low sea ice extents so far this year."21. A. resistant B. respective C. resolved D. remote22.

A. to B. on C. at D. ofReading comprehension(A)I made a pledge (发誓) to myself on the way down to the vacation beach cottage. For two weeks I would try to be a loving husband and father. Totally loving. No ifs, ands or buts.The idea had come to me as I listened to a talk on my car radio. The speaker was quoting a Biblical (圣经的) passage about husbands being thoughtful of their wives. Then he went on to say, "Love is an act ofwill.A person can choose to love." To myself, I had to admit that I had been a selfish husband. Well, for two weeks that would change.And it did. Right from the moment I kissed Evelyn at the door and said, "That new yellow sweater looks great on you."Oh, Tom, you noticed," she said, surprised and pleased, maybe a little puzzled.After the long drive, I wanted to sit and read. Evelyn suggested a walk on the beach. I started to refuse, but then I thought, "Evelyn's been alone here with the kids all the week and now she wants to stay with me." We walked on the beach while the children flew their kites.So it went. Two weeks of not calling the Wall Street firm where I am a director; a visit to the shell museum though I usually hate museums. Relaxed and happy, that's how the whole vacation passed. I made a new pledge to keep on remembering to choose love.There was one thing that went wrong with my experiment, however. Evelyn and I still laugh about it today.Last night at our cottage, preparing for bed, Evelyn stared at me with the saddest expression." What's the matter" I asked her."Tom," she said in a voice filled with distress, "do you know something I don't""What do you mean"" Well...that checkup (体检) I had several weeks ago...our doctor (i)he tell you something about meTom, you've been so good to me...am I dying"It took a moment for it all to sink in. Then I burst out laughing."No, honey," I said, wrapping her in my arms. "You're not dying; I'm just starting to live."76. In the first paragraph, "No ifs, ands or buts" probably means ____.A. UnnecessarilyB. unconditionallyC. impossiblyD. unexpectedly77. During the two weeks on the beach, Tom showed more love to his wife because _____.A. she looked lovely in her new clothesB. she was seriously illC. he was determined to be a good husbandD. he had made a lot of money in Wall Street78.By saying "I'm just starting to live", Tom means that _____.A. he is beginning to feel regretful for what he did to his wifeB. he lived an unhappy life before and is now starting to changeC. he is just beginning to understand the real meaning of lifeD. he is just beginning to enjoy his life as a loving husband(B)As I was thinking about language learning the other day, the image of baking bread came into my mind．I compared some of the exercises and drills that we put ourselves through in order to learn a language to the various ingredients (原料) that go into baking a loaf of fresh bread．Real language learning takes place in human relationships．No one sits down and eats a cup of flour, even if he is hungry and in a hurry．You don' t become bilingual (双语的) by learning lists of vocabulary．You don' tbecome a speaker of a language by memorizing grammatical rules．You become bilingual by entering a community that uses that other language as its basic means of communication．I am not suggesting that we can make bread without ingredients．Flour is necessary, as are yeast (酵母), salt, water and other ingredients．Vocabulary is part of any language and will have to be learned．Grammatical rules exist in every language and cannot be ignored．But merely combining the appropriate ingredients in the recommended proportions does not result in bread．At best, you only end up with a ball of dough (面团)．In order to get bread, you have to apply heat to the dough．And in language learning, that heat comes from the community．Anyone who has learned a second language has experienced that heat．It creeps up your neck when you ask the babysitter “Have you already been eaten” when you meant to say, ‘‘Have you already eaten” When you try to say something quite innocent and the whole room bursts into laughter, you are experiencing the heat that turns raw dough into good bread．Remember the old saying, “If you can' t stand the heat, get out of the kitchen"．This is where language learning often breaks down because we find the heat uncomfortable and we stop the baking process．In other words, we can' t stand the heat, so we get out of the kitchen．However, the language learner who stays in the kitchen－in the heat－until the combined ingredients are thoroughly transformed will enjoy the richness of a quality loaf of bread. He is glad that he did not "get out of the kitchen” at the important moment when the oven seemed too hot.The dedicated language learner knows that becoming bilingual cannot be achieved without the heat.79.According to the author, you can possibly become a speaker of a language by ________．A．bearing millions of words and expressions in your mindB．using the language to communicate with those around youC．Knowing verb conjugations and grammatical rulesD．saying something innocent to be laughed at by others80.'What’s the purpose of illustration of the example-you ask the babysitter,"Have you already been eaten"When you meant to say,"Have you already eaten"A. To verify that you are sure to make some mistakes when you enter a community.B.To show that you should combine the ingredients in the recommended proportions.C. To prove that you may experience"heat"from the community in language learning.D. To indicate that being bilingual calls for your courage, confidence and perseverance.81.According to the passage, which of the following is NOT the necessity of baking bread and learning language?A．Excellent Skills．B．Various ingredients．C．Appropriate proportions．D．Uncomfortable heat．(C)Like most people, I’ve long understood that I’ll be judged by my occupation, that my profession is used by people to see how talented I am. Recently, however, I was disappointed to see that it also decides how I’m treated as a person.Last year I left a professional position as a small-town reporter and took a job waiting tables. As someone paid to serve food to people, I had customers say and do things to me I suppose they’d never say or do to the people they know. One night a man talking on his cell phone waved me away,then called me back with his finger a minute later, saying angrily that he was ready to order and asking where I’d been.I had waited tables during summers in college and was treated like a peon（勤杂工） by plenty of people. But at 19 years old, I believed I deserved inferior（低等的）treatment from professional adults. Besides, people responded to me differently after I told them I was in college. Customers would joke that one day I’d be sitting at their table, waiting to be served.Once I graduated I took a job at a community newspaper. From my first day, I heard a respectful tone from everyone who called me. I assumed this was the way the professional world worked--- politely and formally.I soon found out differently. I sat several feet away from a person in advertising department with a similar name. Our calls would often get mixed up and someone asking for Kristen would be transferred to Christie. The mistake was immediately clear. Perhaps it was because of money, but people used a tone with Kristen that they never used with me.My job title made people treat me with courtesy. So it was a shock to return to be the restaurant industry.It’s no secret that there’s a lot to put up with when waiting tables, and fortunately, much of it can be easily forgotten when you pocket the tips. The service industry exists to meet others’ needs. Still, it seemed that many of my customers didn’t get the difference between server and servant.I’m now applying to graduate school, which means someday I’ll return to a profession where people need to be nice to me in order to get what they want. I think I’ll take them to dinner first, and see how they treat someone whose job is to serve them.82.The author was disappointed to find that_____________83.A. one’s position is used to measure one’s intelligence.B. Talented people like her should fail to get a respectable jobC. one’s occupation affects the way one is treated as a person.D. professionals tend to look down upon manual workers.83. What does the author intend to say by the example in Paragraph 2A. Waiting tables is a hard job.B. Some customers are difficult to deal with.C. The man making a phone call is absent-minded.D. Some customers show no respect to those who serve them.84.What does the author imply by saying"... Many of my customers didn’t get the difference between server and servant (Lines 3-4, Para. 7)A. Those who cater to others' needs are destined to be looked down upon.B. Those working in the service industry shouldn't be heated as servants.C. Those serving others have to put up with rough treatment to earn a living.D. The majority of customers tend to look on a servant as 4. server nowadays.85. The author says one day she’ll take her customers to dinner in order to _______.A. see what kind of person they areB. experience the feeling of being servedC. shoe her generosity towards people inferior to herD.arouse their sympathy for people living a humble life(D)In 1784, five years before he became president of the United States, George Washington, 52, was nearly toothless. So he hired a dentist to transplant nine teeth into his jaw—having extracted them from the mouths of his slaves.That's a far different image from the cherry-tree-chopping George most people remember from their history books. But recently, many historianshave begun to focus on the roles slavery played in the lives of thefounding generation. They have been spurred in part by DNA evidence made available in 1998, which almost certainly proved Thomas Jefferson had fathered at least one child with his slave Sally Hemings. And only over the past 30 years have scholars examined history from the bottom up. Works of several historians reveal the moral compromises made by the nation's early leaders and the fragile nature of the country's infancy. More significantly, they argue that many of the Founding Fathers knew slavery was wrong—andyet most did little to fight it.More than anything, the historians say, the founders were hampered bythe culture of their time. While Washington and Jefferson privately expressed distaste for slavery, they also understood that it was part ofthe political and economic bedrock of the country they helped to create.For one thing, the South could not afford to part with its slaves. Owning slaves was "like having a large bank account," says Wiencek, authorof An Imperfect God: George Washington, His Slaves, and the Creation of America. 'The southern states would not have signed the Constitutionwithout protections for the "peculiar institution," including a clause that counted a slave as three fifths of a man for purposes of congressional representation.And the statesmen's political lives depended on slavery. The three-fifths formula handed Jefferson his narrow victory in the presidential election of 1800 by inflating the votes of the southern states in the Electoral College. Once in office, Jefferson extended slavery with the Louisiana Purchase in 1803; the new land was carved into 13 states,including three slave states.Still, Jefferson freed Hemings' children—though not Hemings herself or his approximately 150 other slaves. Washington, who had begun to believethat all men were created equal after observing the bravery of the black soldiers during the Revolutionary War, overcame the strong opposition of his relatives to grant his slaves their freedom in his will. Only a decade earlier, such an act would have required legislative approval in Virginia.86. In Paragraph 1,George Washington's dental surgery is mentionedto__________A．show the poor medical practice in the past.B．demonstrate the great cruelty of slavery in his days.C．stress the important role of slaves in the entire U.S. history. D．reveal an unknown aspect of his life and introduce the topic87.We may infer from the second paragraph that_____________.A. DNA technology has been widely applied to history research.B. In its early day. s the U. S. was confronted with delicate situations.C. historians deliberately made up some stories of Jefferson's life.D.Political compromises are easily found throughout the U. S. history.88. What do we learn about Thomas Jefferson?A. His political view changed his attitude towards slavery.B. His status as a father made him free the child slaves.C. His attitude towards slavery was complex.D. His affair with a slave ruined his reputation.89.Which of the following is TRUE according to the text?A. Some founding fathers benefited politically from slavery.B. Slaves in the old days did not have the right to vote.C. Slave owners usually had large savings accounts.D. Washington decided to free slaves due to moral considerations. Translation1.社会上，年轻人赶时髦，穿时尚衣服是常有的事。
