A.To show who the passage is written for.B.To gather people’s opinions on childhood.C.To get people’s attention and lead in the topic.D.To compare the childhood lives of two generations.2.Which is a reason for the changes?A.Families are bigger today.B.It’s too dangerous to play outside.C.Children play more interactive games.D.Parents worried too much about their children.3.What does the writer focus on in the fourth paragraph?A.Young people today shouldn’t play electronic games.B.Computer and video games have replaced the board games.C.Some games that young people play today aren’t really good.D.Board games are much more interesting than computer games.4.The writer’s attitude towards the childhood changing is________. A.approving B.objectiveC.unconcerned D.optimisticB(2014·黑龙江省哈尔滨四校高三年级统一检测)There are really two kinds of sleep:good sleep or bad sleep.As college students,we should take our sleeping quite seriously.Sure,we can have a good night’s sleep,but then exams roll in and we have to kick studying into high gear.This kick causes us to sleep less and doze off more.It is a nice feeling every once in a while to doze off while studying or in class,but think about the consequences.Your teachers become angry with you,or your grades can suffer because of a bad test grade.So you try to keep yourself up when you feel that a doze moves slowly to you.Stress can also cause sleep deprivation.We stress over grades,family problems,relationships,and so on.It seems hard for us to get rid of stress,but there is a simple solution to help prevent stress:naps.I’m sure everyone on the planet knows that a nap can be an excellent refresher.So next time you feel stressed just take a nap after class or after lunch.Even though stress is a big reason why people have a hard time falling asleep,there is an even bigger reason.Technology is most likely the major reason why people have trouble falling asleep.We call,text,email,or do some other things at night;I’m guilty of watching TV before I fall asleep.Even while we are sleeping,our phones can ring and interrupt a good night’s sleep.However,some people can sleep so deeply that the phone doesn’t even bother them.Although this may be the case,I’m sure a lot of people would actually answer the phone and immediately fall back asleep. There are many reasons why we have bad sleep,but actually it’s up to us to solve the problem to sleep well.The eight hours of sleep can actually make a difference every day.5.What can we learn from the passage?A.Naps will reduce people’s stress.B.All students are facing sleeping problems.C.Family problems have caused sleep disorder.D.Sleeping makes people more stressed.6.Why do the college students sleep less and doze off more?A.Because they take their sleeping quite seriously.B.Because they have to devote their time to study.C.Because they like to doze off while studying in class.D.Because they play computer games at night.7.We can know f rom the third paragraph that________.A.there is no effective solution to getting rid of stressB.technology causes people to sleep lessC.people prefer watching TV to having a sleepD.the author sleeps like a log in most cases8.It can be concluded from the passage that________.A.watching TV is mainly responsible for less sleepB.it is better to refuse to answer the phone at nightC.we can decide whether we can sleep wellD.getting more sleep a day is the best solutionⅤ.短文改错(2014·陕西省西安市重点中学高三年级联考)My parents live in country.They keep a dog calling Ah Fu.One day my parent went to work in the field take my little sister and Ah Fu along.While they were working,my little sister walked to a river nearby.Ah Fu followed her to there.She was trying to pick a flower w hile she fell into the river.Ah Fu barked and jumped onto the water immediately.When my parents heard Ah Fu barking and ran to the river,we saw Ah Fu swimming towards the bank carrying my little sister.My parents praised Ah Fu warm.It was our brave Ah Fu who has saved my little sister.]课时作业(七)Ⅰ.语音知识1.B 2.C 3.B 4.D 5.AⅡ.单词拼写1.competing 2.bargain 3.deserves 4.ancient 5.hopeless6.replaced 7.charged 8.regularⅢ.单项填空1.解析:考查交际用语。
Unit 2 The Olympic Games课时作业Ⅰ.阅读理解(2019·厦门模拟)Did you know that the color of uniforms can influence the performance of an athlete? It may sound strange,but a study suggests this might be true.Two British scientists studied the results of four sports in the 2004 Athens Olympic Games where the athletes had been given either a red or a blue uniform.They discovered that when there was a big difference in the score,color had no influence on the result.But if it was a close match,the athlete in a red uniform was more likely to win.Then they looked at the uniforms of the soccer teams at the Euro 2004 tournament.Again,teams wearing red won more games.The two scientists got their idea from earlier studies of wild animals.It had been discovered that when a male show red on its body,it sends a signal of its power and strength.For example,in many kinds of monkey,the more the male shows off its red scars,the more females it can attract.Based on this fact,the British scientists thought that the idea might work for humans,too.According to them,when an athlete sees a competitor in a red uniform,he gets a feeling that his competitor could be stronger than him.And that_kind_of_feeling may have a bad influence on the player's performance in the actual game.Although the idea is interesting,most people don't accept that color signals in the animals world can really be useful to humans in sports.They think that it is unreasonable to develop an idea based on such a small number of examples.Much more research has to be done to prove the influence of uniform colors on the performance of athletes.【文章大意】本文属于科普类文章。

Unlike many pop singers,especially those who do not write their own material,Swift has the power of turning her ideas into lyrics that will set people thinking.“Hidden beneath Taylor Swift’s notagirl,notyetawoman sweetness is a very skillful songwriting technique,” wrote Leah Greenblatt in an American magazine.Songwriting,as Swift explains,is to cope with issues.“I tend to write about things that really impact me most.” There certainly seems to be something true and honest running through every one of the 14 songs on her album,Speak Now,about “the lessons and confusion and heartbreak and all the different things that go along with being 18,19 and 20.”“For the audience too young to have experienced real passion or heartbreak,Swift’s songs are like a potential road map,promising things will work ou t OK,” commented Dorian ynskey in a British newspaper.Now Swift is getting ready to go further and has so far written about 10 songs f or her 2012 album,which i s about feelings of growing up and becoming an adult.“They’re sad,if I’m being honest.”“They’re about my heartbreaks and my moving on.But more importantly,they are about achieving contentment.You’re not always going to be perfectly happy as you grow up.”1.What does the writer mean by saying “Werde’s words do not come from nowhere”?A.Swift stands out as a singer and songwriter.B.Only Swift writes her own songs.C.Swift begins to take interest in singing.D.Swift decides to deal with problems in her new album.2.Which of the following statements is NOT true according to the passage?A.Swift has the ability to write songs with deeper meanings.B.Swift is both enthusiastic and skillful now.C.Swift became a multiaward winner when she began to sing on the stage.D.Swift’s album Speak Now has 14 songs.3.Taylor Swift’s 2012 album mainly records________.A.dream and reality B.heartbreak and despairC.pain and growth D.problems and society4.What is the best title for the passage?A.Swift comes to people’s attentionB.Swift rises to fameC.Swift wins many awardsD.Swift experiences real passionB(2013·西安市第一次质量检测)More than half of rich Americans have not shown their full wealth to their children,a new survey showed last Tuesday.The survey,published by the Bank of America,studied the rich with $3 million or more in assets.It found that “surprisin gly few of those surveyed have welldeveloped plans to preserve and pass on their assets to their children”.The majority of the 457 people surveyed are selfmade,firstgeneration rich.Fiftytwo percent of parents have chosen not to tell their children jus t how wealthy they are,and 15 percent have given away nothing about the family wealth.One in three parents said they had never thought to do it.They are worried that their children would become lazy,spend money freely,make bad decisions and even become a target for gold diggers.Only 34 percent strongly agreed that their children would be able to han dle any inheritance (遗产) they plan to leave them.“There is an expectation about the wealthy parents that they have a responsibility to pass down their fortune to the next generation,” said Sallie Krawcheck,president of the Global Wealth and Investment Management of the Bank of America.“Our research,however,uncovered changing views of what one generation owes the next.”The trend is led by the world’s richest m an Bill Gates,who promised in 2008 that he would leave his $58 billion fortune to the charity started by him and his wife,the Bill and Malinda Gates Foundation (基金会),and not to his children.“We want to give it back to society in the way that it will have the most positive impact,” he said.Of his plans for his children,Gates said:“I will give the kids some money but not a meaningful percentage...they will need to work but they will feel reasonably taken care of.”5.We can learn from the passage that________.A.rich parents may not know how to manage their inheritanceB.rich parents don’t equal rich kids,at least in the USC.American children don’t get to inherit their parents’ wealthD.poor children don’t expect themselves to be as rich as their parents 6.According to the survey,most rich Americans________.A.think they owe their children nothingB.think it best to give their money back to societyC.doubt their children’s ability to handle wealthD.are confid ent of their children’s ability to handle wealth7.The underlined word “they” in Paragraph 6 refers to________.A.responsible children B.Bill Gates and his wifeC.firstgeneration rich D.rich parents8.From the last paragraph,we can see that Bill Gates wants to show________.A.the trend of leaving no inheritance to childrenB.the positive impact of charity on societyC.the way of giving back to societyD.the importance of independence for children答案:课时作业(七)Ⅰ.单项填空1.解析:考查情景交际。
Unit 2 The Olympic GamesⅠ.阅读理解A(2021·山西太原高三模拟试题)At 39 weeks pregnant most women would only be thinking of racing to hospital. But not Amber Miller, who set off to run the Chicago Marathon while expecting her second child any day.As she neared the final stage of the race, she began to feel pain in the stomach. But the determined athlete managed to cross the finish line in 6 hours and 25 minutes.Unbelievably the Chicago race was not even baby June's first marathon —Miller ran the Wisconsin Marathon earlier this year, four months pregnant. She also ran another marathon when she was about four months pregnant with her son, Caleb.Although there was extra weight, the seasoned runner's time was just 3 hours off her personal best.Miller began to feel pain near the end of the race, but she was not sure if it was labor (临盆), because she typically feels some pain when she runs while pregnant. After her race her husband drove her to Central DuPage Hospital in Winfield where she gave birth to the healthy 7 pounds, 13 ounce baby.Miller decided to run because she and her husband had already signed up for the race. The athletic mother said she experienced an enthusiastic welcome from crowds as she ran along. But the devoted runner, who had completed eight marathons, admitted that she did get a few strange looks along the course.“I know what I can handle. This is something I've been doing for a long time,” the experienced marathon runner said.June was born at 10:29 p.m. on Sunday night after seven hours' labor. “She's absolutely perfect,” Miller said. “We are extremely happy, but very tired.”After her surprising double achievement, Miller says she is planning to take some time off to concentrate on being a fulltime mom.【解题导语】本文讲述了在芝加哥马拉松赛上,Amber Miller已怀孕39周,但她坚持用6个小时25分钟完成了马拉松赛并在当晚产下了小女儿June。
核心素养测评七必修2 Unit 2 The Olympic Games(限时35分钟)Ⅰ. 阅读理解ABreakdancing is set to make its debut(首次亮相) as an Olympic sport at Paris 2024, Tony Estanguet, head of the Paris organizing committee, said on February 21. Skateboarding, sport climbing and surfing which have already been added to the 2024 Tokyo Olympics, have been invited to return in Paris.Estanguet said the choices responded to a need to make the Olympics “more urban” and “more artistic”. “We have chosen to present the International Olympic Committee (IOC) with the four sports because they are creative, appealing to youth and completely in line with our vision. They reflect perfectly Paris 2024’s identity. ”Breakdancing is an example of a sport “which can be played anywhere and anytime in urban and other environments. ” It appeared at the 2024 Youth Olympics in Buenos Aires in the form of head-to-head “battles”. In competitive breakdancing, breakers face off in “battles” against each other, either as individuals or teams. Breakdancers use a mix of physical and artistic skills combining elements from gymnastics or acrobatics(杂技).The IOC had announced that the number of competitors at Paris 2024 would be restricted to 10, 500, which limited the opportunity to add sports. But the organizers said the inclusion would not necessitate the construction of permanent facilities and would involve just 248 competitors, including 32 breakdancers. The surfing events are likely to be held in established surf center such as Biarritz or Lacanau in southwest France.The inclusion still needs to be rubberstamped by the IOC, which is expected to decide on which sports to add in Paris after next year’s Tokyo Games.【文章大意】这是一篇新闻报道。

Where do they come from? What do they mean?People's first names, or given names, are chosen by their parents.Sometimes the name of a grandparent or other members of the family is used.Some parents choose the name of a wellknown person.A boy coul d be named George Washington Smith; a girl could be named Helen Keller Jones.Some people give their children names that mean good things.Clara means “bright”;Beatrice means “one who gives happiness”;Donald means “world ruler”; Leonard means “as brave as a lion”.The earliest last names, or surnames, were taken from place names.A family with the name Brook or Brooks probably lived near a brook(小溪);someone who was called Longstreet probably lived on a long, paved road.The Greenwood family lived in or near a leafy forest.Other early surnames came from people's occupations.The most common occupational name is Smith, which means a person who makes things with iron or other metals.In the past, smiths were very important workers in every town and village.Some other occupational names are: Carter—a person who owned or drove a cart; Potter—a person who made pots and pans.The ancestors of the Baker family probably baked bread for their neighbours in their native village.The Carpenter's greatgreatgreatgrandfather probably built houses and furniture.Sometimes people were known for the colour of their hair or skin, or their size, or their special abilities.When there were two men who were named John in the same village, the John with the gray hair probably became John Gray.Or the John who was very tall could call himself John Tallman.John Fish was probably an excellent swimmer and John Lightfoot was probably a fast runner or a good dancer.Some family names were made by adding something to the father's name.Englishspeaking people add ed s or son.The Johnsons are descendants of John; the Roberts family's ancestor was Robert.Irish and Scottish people added Mac or Mc or O.Perhaps all of the MacDonnells and the McDonnells and the O'Donnells are descendants of the same Donnell.11.Which of the following aspects do the surnames in the passage NOT cover? A.Places where people lived.B.People's characters.C.Talents that people possessed.D.People's occupations.12.According to the passage, the ancestors of the Potter family mostprobably________.A.owned or drove a cartB.made things with metalsC.made kitchen tools or containersD.built houses and furniture13.Suppose an English couple whose ancestors lived near a leafy forest wanted their newborn son to become a world leader, the baby might be named________.A.Beatrice Smith B.Leonard CarterC.George Longstreet D.Donald Greenwood14.The underlined word “descendants”in the last paragraph means a person's________.A.later generations B.friends and relativesC.colleagues and partners D.later sponsorsBSome people love eating food right after it is cooked.I prefer food just taken out from the freezer.Fruit, candy, nuts, chocolate, cakes with butter cream frosting(糖霜), even peas, all of them taste delicious when frozen.In fact, I often eat them that way.I was a kid when I picked up the habit.In my family, lots of things were thrown into the freezer finally, two freezers to prevent them from going bad.Among them were some of the candies my sisters and I had collected on Halloween.If we eat when they are still warm, we'll find ourselves taking the cookies more than we should.It's better if we can put them into the freezer and wait.That way we'll eat less and enjoy them more because they are hard and chewing becomes a slower, more patient effort.That's the point about frozen butter cream frosting.Put it in your mouth at room temperature, and it's gone very quickly.But when it's frozen, you can enjoy the taste much longer as it melts(融化) in your mouth.The freezer treats a lot of fruit kindly.Take frozen grapes for example.I keep a bowl of grapes in my freezer.They become a little icy, and somehow their sweetness is improved.They are the perfect and healthy dessert.This is the same with oranges, apples, bananas…You might think bananas would get superhard when frozen.Wrong! They become cool, creamy and sweet.If you have wisely covered some or all of the bananas with melted chocolate before putting them into the freezer, they will have a double taste.As long as you aren't eating anything that truly has to be hot, go ahead and experiment.15.What is the passage intended to tell us?A.Fruit should be frozen before one eats it.B.Frozen food is better than hot food.C.The author prefers frozen food.D.Hot food is not healthy.16.Why doesn't the author advise us to take hot cookies?A.Because they need more time to prepare.B.Because the taste is not good when they are hot.C.Because they are too delicious to avoid our overeating.D.Because we may eat them quickly and enjoy them less.17.What does the underlined word “it” in the third paragraph refer to? A.The taste.B.Butter cream.C.The cookie.D.Frozen butter cream frosting.18.Which of the following is the advice the author gives on eating fruit?

There are currently 791 pupils on the school roll(名单). The school has a long and distinguished history, and it is also one of the oldest charities in the country, providing scholarships to pupils and organizing a Charity of the Term.The curriculum(课程) at King's is based on strong academic roots. It emphasizes and relies upon what is best in traditional independent school education: scholarly excellence supported by a caring and tutorial system, and a wideranging cocurricular programme. However, it is continually adapting and reacting to the changing demands of modern education: new subjects are added, new teaching techniques are adopted, and there is an increasing awareness of the need to provide programmes of study that match individual needs and skills.The curriculum is divided into three units: the Lower School(Year 9 ), an introductory year; the Middle School(Years 10 and 11 ), working to GCSEs; and the Sixth Form(Years 12 and 13), taking AS and A levels.Full details can be found in: Shell Guide and Handbook; Middle School Academic Guide 2009—2011; Middle School Academic Guide 2010—2012; Sixth Form Guide 2009—2011 and Sixth Form Guide 2010—2012.Formal and structured educational support, for those who need it, is available at all levels. The wellstocked library is open 7 days and 6 evenings pe r week. ICT facilities (including the Internet) are available for all and the whole school(studies within the houses as well as classrooms) is extensively networked.Pupils are offered extensive career advice throughout their time at King's. Almost all go to university, either immediately or following a GAP year. The most popular university destinations are Cambridge, Bristol, Nottingham, Durham, Leeds, Oxford, Edinburgh, Manchester, and University College, London.Director of Studies: Geoff Cocksworth: grc @ kingsExaminations Officer: Elaine McDowell: eam @ kingsschool. co. uk.Click here for more information.11.The best title of the passage might be ________.A.The King's SchoolB.The Curriculum in BritainC.New Teaching TechniquesD.British Education System12.Which of the following is NOT true according to the passage?A.The King's School, Canterbury is a famous high school in Britain.B.The curriculum at King's is best in traditional and modern education.C.All pupils of the school go to university immediately after they graduate.D.Pupils' dormitories as well as classrooms are provided with network.13.The following can be inferred from the passage EXCEPT that________.A.the King's School focuses on pupils' individual developmentB.pupils in the King's School who pass GCSEs will go to universityC.pupils in the King's School have an easy access to the school library D.pupils in the King's School receive good education14.The passage is probably taken from a ________.A.handbook B.websiteC.magazine D.newspaperBThe average temperature around the world is rising. People living in the US Midwest might find a fact hard to believe, though. The scientists suggest that the change in the Midwest climate may have happened because of farming.The first study was led by David Changnon, a climatologist(气候学家) at Northern Illinois University in DeKalb.Changnon and his team studied temperature records from the sites in the Midwest. They found that since 1970, the average temperature in the region during July and August has gone down—by up to one degree Fahrenheit(华氏度)—from what it was during the years between 1930 and 1969. Their investigation also showed that the average rainfall in those states during those two months has increased. Between 1970 and 2009, about 0.33 inch more rain fell than between 1930 and 1969.These_changes may be connected by humidity(湿度), Changnon says. Humidity is the measure of how much moisture is in the air. Humid air, which contains a lot of moisture,takes longer to heat up than dry air, Changnon notes. And humid air often releases its moisture through rainfall.So where did the extra moisture in the air come from?Changnon points to farms in the region. As plants grow, they pull moisture from the ground and release it into the air. And among plants, soybeans (大豆) and corn plants release a lot of moisture. Midwestern farms now plant more soybeans and corn than in the past, with 97 percent of farmland today planted with these two crops. In the 1930s, corn and soybeans covered only about 57 percent, Changnon says. He also notes that the plants are planted closer together now than they used to be, so there are more plants per acre than in the past.The second study, like Changnon's, also found an increase in rainfall in the same area. But it points to another possible source for the increased moisture. Alan Robock at Rutgers University was part of the team that produced the second study and presented the group's findings. The team found that irrigation practices in the Great Plains have changed over the years. The researchers studied a vast area in the region. They found that in 1930, farmers in that region irrigated only about 1.8 million acres of farmland. In 1980, however, farmers irrigated nearly 15 million acres. Plants use the water and then release it into the air.These results by Changnon and Robock and their colleagues are the first step toward understanding a change in the weather.15.What does the underlined term “These changes” refer to?A.Lower temperatures and more rainfall.B.Higher temperatures and higher humidity.C.Making a record both in the past and now.D.The two periods of the 40year investigation.16.Which of the following could be the possible sources for the increased moisture in the US Midwest?A.Scientists' research and farmers' attention.B.Less farmland and more plants.C.More plants and irrigation practices.D.Natural reservoirs and underground rivers.17.The studies show that in America's Midwest,________.A.the average temperature is getting higher and higherB.more and more farmland has been desertedC.the amount of rain is closely related to the temperatureD.summers are now cooler and wetter than they were in years past18.According to the passage, irrigating more and more plants means ________.A.making more space for farms and buildingsB.making more and more water into the air, and thus causing more rainC.more farms depending on watersaving systemsD.using plants to change the climateⅢ.完成句子19.An order came that all the vehicles having seven or fewer seats __________________________________________ on the highway during the eightday holiday.

You listen to their conversation:“I can't believe it—Lorenzo Bertolla! They are almost impossible to find. Isn't it beautiful? And it's a lot cheaper than the one Sara bought in Rome.”They leave and you go over to see this incredible sweater. It's nice and the price is right. You've never heard of Lorenzo Bertolla,but those girls looked really stylish. They must know. So,you buy it. You never realize that those young women are employees of an advertising agency.They are actually paid to go from store to store,talking loudly about Lorenzo Bertolla clothes.Every day we notice what people are wearing,driving and eating. If the person looks cool,the product seems cool,too. This is the secret of undercover marketing. Companies from Ford to Nike are starting to use it.Undercover marketing is important because it reaches people that don't pay attention to traditional advertising. This is particularly true of the MTV generation—consumers between the age of 18 and 34. It's a golden group. They have a lot of money to spend,but they don't trust ads.So advertising agencies hire young actors to “perform” in bars and other places where young adults go. Some people might call this practice misleading,but marketing executive Jonathan Ressler calls it creative. “Look at traditional advertising. Its effectiveness is decreasing.” It is true,because everyone knows an ad is trying to persuade you to buy something. However,you don't know when a conversation you overhear is just a performance.11.The two attractive young women were talking so as to ________.A.get the sweater at a lower priceB.be heard by people aroundC.be admired by other shoppersD.decide on buying the sweater12.Lorenzo Bertolla is ________.A.a very popular male singerB.an advertising agencyC.a clothing company in RomeD.the brand name of clothes13.What can we infer from the passage?A.Traditional advertising will soon disappear in the market.B.The MTV generation tends to be more easily influenced by all kinds of ads.C.Traditional advertising is becoming less effective because it is too direct.D.Undercover marketing will surely be banned soon by the government.14.Which of the following would be the best title for the passage?A.Two Attractive ShoppersB.Lorenzo Bertolla SweatersC.Ways of AdvertisingD.Undercover MarketingB“Our aim is to take ou r art to the world and make people understand what it is to move,” said David Belle, the founder of parkour(跑酷).Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.Overcoming all the obstacles on the course and in life is part of the philosophy(理念)behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life to reach the destination successfully. A parkour lover said, “I love parko ur because its philosophy has become my life, my way to do everything.”Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at anytime, anywhere in the world. It is a kind of expression of trust in yourself. It is only a state of mind. It is when you trust yourself that you earn energy.15.Parkour has become popular throughout the world because of ________.A.its founder, David BelleB.the film, Casino RoyaleC.its risks and tricksD.the varieties of participants16.The underlined word “obstacles” in Paragraph 2 is closest in meaning to “________”.A.streets B.objectsC.barriers D.roofs17.Which of the following is true of parkour?A.It challenges human abilities.B.It is a good but boring sport.C.It needs special training.D.It is a team sport.18.As its participants move around a city, ________.A.they can ask for helpB.they may choose to escapeC.they should run to extremesD.they must learn to surviveⅢ.完成句子阅读下列各小题,根据每句后的汉语提示,用句末括号内的英语单词完成句子。

Among professional basketball players, Jeremy Lin's background is not typical. He graduated from Harvard University, which sends few players to the NBA, and he is the only Chinese American NBA player. But when you watch him on the court, there is no doubt that he belongs there. He moves with speed and grace that demonstrate years of faithful practice, which is fueled by a love for basketball.Lin's enjoyment of basketball actually began in Taiwan. When Lin's father moved tothe US, his interest in the sport only grew and he passed on this love of basketball to his son, introducing him to the game at the age of five. The young Lin spent much of his youth playing basketball for fun.In high school, Lin dreamed of playing in the NBA. When he applied for college, he was not offered a single sports scholarship. However, after his admission to Harvard, he was offered a place on its college basketball team.During Lin's time at Harvard, his basketball career began to speed up. He scored 1,482 points, making him one of the highest scorers in Ivy League's history. When he graduated, no professional teams offered Lin a contract, but he was invited to play in the NBA Summer League. He played well and ended up eagerly signing a contract with the Golden State Warriors.At first, playing in professional games filled Lin with excitement. He treasured opportunities to meet players he had been watching on TV for years. But slowly, the excitement wore_off and was replaced by anxiety. In a few very difficult months, he was cut by two teams before the New York Knicks picked him up.But he had the courage and determination to stick to his dream, so he put himself into hard training to get ready for his opportunity to come. Then his moment arrived on February 4,2012, on which his excellent performance made him famous overnight. After that, he led the Knicks to their fifth straight victory.The Associated Press called Lin the most surprising storyin the NBA. Knicks fans developed the nickname for him “Linsanity(林发疯)”. Time magazine released its 2012 list of the 100 “Most Influential People in the World”, Jeremy Lin included. No doubt, Lin fever is continuing to spread and if you haven't already caught “Linsanity”, get ready.11.Which of the following elements is of little help in Lin's success?A.His father's influence.B.His devotion to basketball.C.His years of hard work.D.His graduation from Harvard University.12.The underlined phrase “wore off”in seventh paragraph probably means “________”.A.arose B.disappearedC.grew D.remained13.Which of the following statements is TRUE according to the passage?A.Lin learned to play basketball when he was eight.B.Before Lin there was no Chinese American NBA players.C.Lin was excited for professional games and did a good job at the beginning. D.Lin is the most outstanding player in the NBA.14.Which is the right order for Lin's life?a.He made an excellent performance on February 4.b.He was fired by the Golden State Warriors.c.He was invited to play in the NBA Summer League.d.He graduated from Harvard University.e.He became famous overnight.A.a, d, c, b, e B.d, b, c, a, eC.d, c, b, a, e D.a, e, d, c, b15.It can be inferred from the passage that ________.A.NBA prefers graduates from Harvard UniversityB.Lin got an easy entry into NBAC.Lin didn't show his basketball talents in Harvard UniversityD.Lin didn't have a smooth road in the NBABWhenever anyone measures educational success, East Asian countries are always top scorers. But in a recent league table, a European country, Finland, was top of the class. Korea was still in second place, though. Britain was at number 6.In Korea the school day is long—typically 7 or 8 hours, followed by hours of private tutoring in the evenings. All_this_hothousing leaves Korean students so tired, and they sometimes fall asleep in class next day. Worries about the effects of late night cramming(填鸭式) led the government to force cramming schools to close by 10 pm. Finnish children spend the least time in class in the developed world, often finishing just after lunch, with about one hour of homework a day. Private tuition is uncommon. The British and American school day is quite long in comparison, around 6 hours, and secondary school pupils do 2 or 3 hours of self-study a night. The Korean education system, like many in Asia, is intensely competitive, with students even competing to get into the best cramming schools to help them get ahead. Finnish education is far less cut-throat. Classes are all mixed ability, and there are no league tables. British schools again occupy the middle ground, with quite high levels of competition for places at university, and schools and universities battle to come top of league tables for everything from exam results to student satisfaction. Korea and Finland both do well, yet their education systems are so different.However, there are some similarities in Korea and Finland. In those countries, teachers have high status in society, and education is very highly valued. Those attitudes can't change quickly. But it can be done. They might be the star pupils now, but until the 1970s, Finland's educational system was poor. Their thoroughly different approach to schooling has taken them to the top in just a generation. 16.The students spend the least time in school in ________.A.the UK B.FinlandC.the USA D.Korea17.According to the text, we think in Korea ________.A.students spend more time in studyingB.students are tired of studying in classC.students leave their school earlyD.students are always top scorers18.The underlined phrase “All this hothousing” in Paragragh 2 probably refers to “________”.A.private evening tutoring B.self-study at homeC.long-hour study D.school study19.From Paragragh 3, we can know that ________.A.Finnish students are less stressed in studyB.there're also many cramming schools in BritainC.students in Korea are the most competitive in AsiaD.British schools are less competitive than universities20.According to the author, the key to improving education is ________.A.the attitude B.the schooling timeC.star pupils D.the new teaching approachⅢ.读写任务阅读下面的短文,然后按照要求写一篇150词左右的英语短文。
Unit 2 The Olympic GamesⅠ.阅读理解A(2017·山西太原高三模拟试题)At 39 weeks pregnant most women would only be thinking of racing to hospital. But not Amber Miller, who set off to run the Chicago Marathon while expecting her second child any day.As she neared the final stage of the race, she began to feel pain in the stomach. But the determined athlete managed to cross the finish line in 6 hours and 25 minutes.Unbelievably the Chicago race was not even baby June's first marathon —Miller ran the Wisconsin Marathon earlier this year, four months pregnant. She also ran another marathon when she was about four months pregnant with her son, Caleb.Although there was extra weight, the seasoned runner's time was just 3 hours off her personal best.Miller began to feel pain near the end of the race, but she was not sure if it was labor (分娩), because she typically feels some pain when she runs while pregnant. After her race her husband drove her to Central DuPage Hospital in Winfield where she gave birth to the healthy 7 pounds, 13 ounce baby.Miller decided to run because she and her husband had already signed up for the race. The athletic mother said she experienced an enthusiastic welcome from crowds as she ran along. But the devoted runner, who had completed eight marathons, admitted that she did get a few strange looks along the course.“I know what I can handle. This is something I've been doing for a long time,” the experienced marathon runner said.June was born at 10:29 p.m. on Sunday night after seven hours' labor. “She's absolutely perfect,” Miller said. “We are extremely happy, but very tired.”After her surprising double achievement, Miller says she is planning to take some time off to concentrate on being a fulltime mom.【解题导语】本文讲述了在芝加哥马拉松赛上,Amber Miller已怀孕39周,但她坚持用6个小时25分钟完成了马拉松赛并在当晚产下了小女儿June。

B(2017·山西四校联考)For most caffeine (咖啡因) consumers, its chief benefit is that it helps you get more done. This is what makes it unusual, says Stephen Braun, author of Buzz:The Science and Lore of Alcohol and Caffeine.“Its appeal is that it helps u s earn more money,” he adds. “What makes it different from other drugs is that it's used as a productivity tool — not for pleasure.”Many of history's creative minds have also been associated with a large amount of caffeine consumption.According to one biographer, the French novelist and playwright Balzac drank as many as 50 cups of coffee a day. “Were it not for coffee, one could not write, which is to say one could not live,” he once insisted.For seven years, the filmmaker David Lynch ate at the same L os Angeles diner every day, drinking up to seven sweetened cups of coffee “with lots of sugar” in one sitting, which he said would guarantee that “lots of ideas” arrived.Ludwig van Beethoven was said to have painstakingly counted out exactly 60 coffee beans per cup when he brewed (煮) coffee.Perhaps recent tales of caffeine excess featured the singer Robbie Williams, who reportedly consumed 36 cups of black coffee and 20 cans of Red Bull a day.It is the routine task itself, as much as the stimulant (刺激的) effects of caffeine, that makes the process so important, says Mason Currey, author of Daily Rituals: How Artists Work.“A lot of artists use the process of making coffee as a gateway to the creative process,” he adds. “You need to get into the right mindse t to do that sort of work, and the preparation process provides a focus.”One problem with attempting to control caffeine, says Braun, is that it affects everyone differently —it is impossible to work out a “safe” limit that works for everyone. “Eventuall y, you have to become your own scientist — there isn't an alternative to careful selfexperimentation,” he says.【解题导语】本文讲述了喝咖啡不仅可以帮助人们提神和提高工作效率,而且还可以帮助艺术家们获得灵感。
