教育最新K12四川省宜宾市一中2017-2018学年高三英语上学期第4周试题

四川省宜宾市一中2017-2018学年高三英语上学期第4周试题2015级高三上期第4周英语试题第一节(共15 小题;每小题2分)阅读下列短文,从每题所给的四个选项(A、B、C 和 D)中,选出最佳选项。

AFor many people in the US, sports are not just for fun. They’re almost a “religion”. Thousands of sports fans buy expensive tickets to watch their favorite teams and athletes play in person. Other fans watch the games at home, sticking to their TV sets, never missing a game. Many a wife becomes a “sports widow” during her husband’s favorite season. America’s devotion to sports has created a new class of wealthy people ---professional athletes. Sports stars often receive million-dollar salaries. Some even make big money by appearing in advertisements for soft drinks, shoes and almost everything.Sports are an important part of American culture. Throughout their school life, Americans learn to play many sports. Many students try out for the school teams. Athletic events at universities attract scores of fans and benefit the whole community. Many people also enjoynon-competitive activities, like hiking, cycling, horseback riding, camping or hunting.Many sports were imported from other countries. Europeans brought tennis, golf, bowling and boxing to America. Football and baseball came from other Old World games. Only basketball has a truly American origin. Americans export sports fever as well. Satellites broadcast games to sports fans around the globe. NBA is a good example. The names of American superstars like basketball giant Michael Jordan have become household words all over the world.1. We can infer from the first paragraph that the meaning of “widow” is .A.one who is serious in religionB. one who is devoted to sportsC. one who lost her husbandD. one who has interest in games2. Which of the following is NOT true according to the passage?A. The US sports stars can earn a large sum of money via the media.B.American students go in for various sports and athletic events.C.Lots of American people take part in non-competitive activities.D.American people like to exchange different sports from each other.3. The writer mainly intends to tell us _.A. how important sports are in AmericaB. where sports can help to make moneyC. why sports are so popular in AmericaD. what affect Americans’ everyday lifeBOf all the animals in the animal kingdom, which one (aside from man) is the cleverest?There are several ways of measuring the intelligence of animals. In one test a scientist sets three samecans on a table. While the animal watches, he puts food under one of the cans. Then he leads the animal away. Some time later, he brings it back to see if it remembers which can has the food. No smelling is allowed; the animal must go directly to the correct can or it fails.This is called a delayed- response text. The idea is to find out how long an animal’s memory can keep information. The scientists would try showing the cans to the animal one hour later, or two hours later, or even a full day later. They discovered that chimpanzees and elephants had the best memory, and were able to remember the correct can for at least twenty hours. No other animal is close. Dogs came next, but they only remembered for nine hours.To settle the matter, the scientists designed a huge maze (迷宫) and ran the chimps and elephants throughit. The maze was very difficult, with many blind paths and dead ends. It took the chimps (chimpanzees) ten minutes to find their way out. The elephants needed half an hour. Even allowing for the elephants’ slower rate ofspeed, the test shows that chimpanzees are the cleverest animals.From this and other tests, the scientists drew the following conclusion: an animal’s intelligence depends on the size of its brain in proportion (比例) to the size of its body. The elephant’s brain weighs ten pounds. But this is only 1/600th of its 6,000 pounds body.A chimp’s brain weighs about one pound, or 1/120th of its total body weight. So in proportion to its body size, the chimp has four times as much brain as the elephant----more brain for less body. The chimp is the champ!4. Which is the best title?A. The Elephant’s MemoryB. The Cleverest AnimalC. Judging IntelligenceD. The Chimp’s Brain5.According to the passage, a rhinoceros (犀牛) that weighs 2100 pounds, and has a 3-pound brainis .A. as clever as a chimpB. more clever than an elephantC. less clever than an elephantD. as clever as an elephant6. The delayed-response test is designed to test an animal’s.A. eyesightB. brainC. learning abilityD. memory7. The passage tells that elephants _.A.never forget thingsB. are more clever than chimpsC. are slower-moving than chimpsD. have better memories than chimpsCTrends come and go but style is eternal(永恒的) .So what is the latest fashion trend that defines thisseason? Let’s take a look at the fashion trend in 2016 and be the first ones to embrace the latest trend.Head----It seems like everyone will be wearing a bucket hat(渔夫帽) this season. Bucket hat might sounda bit old-fashioned for some people, but the 90s trend is in season again! Spring and summer are always the seasons for casual clothes, so pairing the bucket hat with casual shorts or skirts would be your outfit to go in this spring and summer in 2016.Bottom—Summer is the season when everyone gets ready for the humid weather. The current season trendis making everyone have a more comfortable summer because wide-leg bottoms is in trend again. Perhaps not everyone likes wide-leg bottoms because this could possibly make people look shorter, choosing a high-waist wide-leg bottom and matching it with crop top will definitely make you look taller and trendy in 2016.Dress---Be prepared for embracing the feminine details this season. Ruffles(荷叶边)around the sleeve orruffles all-over the dress will be everyone’s favorite in 2016. All these little details will transform your look in season. Simple colors like pink and black are designer’s favorites in this season too.Shoes---Many people thought wedges are also the shoes to go in spring and summer time, but in 2016, veryflat flats are in trend again. Shoe designers are trying to have more combinations flats or low-heels with less of gender identity.Accessories----No outfit goes perfect without accessories. Adding statement accessories to your simpleand natural outlook this summer is your day-to-night outfit. These jewels are doing to make you feel completed in day time and sparkled at night.8. What kind of people will benefit a lot more from this passage?A. Scientists B Teachers C. Designers D. Lawyers9. Which of the following is true about bucket hats in the second paragraph?A. Everyone is wearing a bucket hat.B. Bucket hats in the 90s were old-fashioned.C. Nowadays most people do not like bucket hats.D. Maybe you will match the bucket hat with casual shorts this spring.10. From the passage we know that in 2016 .A. accessories will be an important part of the fashionB. shoe designers are trying to have high-heelsC. jewelry is not considered a fashionable itemD. simple and natural outlook this summer is your day-to-night outfit11. What will fashion icons do in 2016 except .A. prefer flat shoesB. prefer complex colorsC. wear dresses with ruffles(荷叶边) around the sleevesD. choose a high-waist wide-leg bottom and match it with crop topDHollywood is on the edge of a nervous breakdown. Worried about an industry wide writers’strike, struck by a series of theater-chain bankruptcies(破产), burdened with unreasonable corporate profit, requirements and seemingly incapable of producing consistently creative movies, the American film industry is in a period of soul-searching. There’s little doubt it will survive this crisis. But most insiders agree there is disease at both ends of the business—where films are produced, and where they’re shown---that may take years to overcome.While annual box-office income increases for nine straight years, largely due to increased ticket prices, the number of actual tickets sold declined for the second year in a row. The construction boom has added nearly 10,000 theaters (more than 200,000 more seats) in the last five years. But due to a static(静止的)audience base, eight major chains have gone into bankruptcy and several others are in terrible financial situations.In fact, insiders say, Hollywood is now in a business it does not want to be in. “There’s a general problem because the companies that have the most consistent output of material are least interested in what they’re making,” says former 20th Century Fox CEO, Bill. And, Bill adds, “We’re in a period where movies are getting bigger and more costly and less interesting and fulfilling to an audience.”Today the studios are under the stress to increase profit margins(营业利润) for their corporate parents, and profit margins are hard to control in a business whose products are seen as impulse buys. Other business can increase profits by cutting costs—buying cheaper material, or making the candy bar smaller. Not Hollywood.“What we’re cutting is risk,” says the head of one major studio, who asked not to be named, “And risk is what great film has always demanded.”While the studios are avoiding risky concepts, their competitors in the home entertainment business have been expanding the boundaries of the imagination. It was this pressure---in electronic games, the Internet----that forced the movie theater chains into a self-destructive craze of expansion.12.Which is NOT the worry of the American film industry according to the passage?A.Theater-chain bankruptcy.B. Lack of the advertisement funds.C. The stress to increase corporate profit.D. Being unable to produce creative movies.13.What has directly caused major theater-chains in terrible financial situations?A.Bigger movies.B. More costly movies.C. Increased ticket prices.D. More theaters but an unchangeable audience base.14.What do we know about the profit of the film industry?A.It’s not easy to control the profit.B.The studios can shorten the material.C.Cutting the cost can increase the profit.D.The studios can buy cheap material to increase profits.15.What’s the main idea of the passage?A.Hollywood will survive financial crisis.B.Hollywood is on the edge of destruction.C.It’s hard to increase the profits of the studios.D.The construction boom leads to theater-chain bankruptcies.第二节(共5小题; 每小题2分,共10 分)根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。

One morning we'd just taken down our tent and started skiing (滑雪). Pen was in front, and I was following him. Suddenly I got a strange feeling that something was behind us. I stopped, looked back and saw a polar bear, walking towards us.Pen and I planned to stay where we were, try and look big, and frighten it away. Pen had a shotgun that we'd bought in Russia. That was his job. My job was to look big and to take off my skis, hold the skis in the air, make lots of noise, and frightenaway the bear. Pen raised the gun and fired into the air. However, it jammed and failed to work.The bear was walking towards us. Pen tried again, but again it didn't work. Then he walked towards the bear, and I thought, “Wow, Pen's gone completely mad. He's going to get eaten. What should I do?”I thought maybe I could throw a ski at it or stab (刺) it with a ski pole or something. Suddenly, the bear stopped. Pen stopped. Bang. The gun went off in the air. There was a big cloud of smoke that I think surprised Pen and me more than it surprised the bear. The animal looked up, looked down, turned around and walked off. Pen turned round and said, “Quick, get the camera and take a photograph,” and that was when suddenly I felt really nervous. I couldn't even undo the zip on our bag.That was the morning of the second day of this journey. We were out there for two months — fifty-nine days, but we never saw another bear that close.25.

In the text, the author mainly talks about _____.A. his discovery in the North PoleB. his experience in the North PoleC. why he traveled to the North PoleD. how he traveled across the North PoleCIn Britain, many theatres put on shows for children at Christmas and many theatres have a theatre-in-education team working there. This team, made up of actors and teachers, writes plays for children, usually performing them in schools. They do different plays for different age groups and the children often take part in the play in some way.Pantomime is a special kind of Christmas show for children. It is loved by people and also allows the audience to join in. “Pantomime” was the name of the Roman actor who performed shows without speaking —this is where the English word “mime” comes from.A pantomime is always based on (以……为根据) a well-known children's story. But there are always certain types of characters in the show and certain situations and events. For example, a pantomime must always include a hero, known as the “principal boy” and this principal boy is always played by a pretty girl wearing a short costume (服装). Then there is the comic older woman, known as the “dame” who is played by a man. There is always a group of men and women who sing and dance and often there is a pantomime horse. The horse is played by two men who form the “front” and “back” ends inside a “horse” costume. It is funny and it usually kicks the dame when she isn't looking.Members of the audience have to shout a warning to one of the characters and argue with the character (usually the dame) when she does not believe them. When she shouts, “Oh no, it isn't,” the audience always responds (回应) with “Oh yes, it is!” Theaudience also learns and sings a simple song and a few children are sometimes invited to help one of the characters during the show.29. The theatre-in-education teams _____.A. are made up of famous local actorsB. write plays for the same age groupC. often give plays in their own theatresD. usually allow children to join in a play30. According to the text, a pantomime _____.A. is designed to make people laughB. is made up of three charactersC. is especially popular with grown-upsD. can be watched all year round in Britain31. When the dame says, “Yes, it is”, the audience should _____.A. follow her and singB. stand up and danceC. repeat what she saysD. disagree with her loudlyD“One thing I enjoy about my job is that I can work on something that is actually active,” says Game McGimsey, an American volcanologist. Part of his job includes keeping an eye on Alaska's many active volcanoes and giving people a heads-up when a volcano might erupt.Like most jobs in the sciences, volcanology requires a lot of education. McGimsey received an undergraduate degree in geology at the University of North Carolina, then landed an internship (实习期) with a geologist at the USGS (美国地质勘探局) whose area ofexpertise was volcanoes. After earning a graduate degree at the University of Colorado, McGimsey accepted a job with the USGS and has been with the Alaska Volcano Observatory for 25 years.Volcanoes can influence the world in ways we might not think about. For example, on Dec. 15, 1989, a 747 jetliner (a large airplane) flew through a thick ash cloud produced by Mount Redoubt, an Alaskan volcano that hadn't erupted in 25 years. The ash caused all four engines to die, and the plane's electronics went dead.“The plane was within several thousand feet of flying into the mountains below when the pilots got a couple of the engines restarted and landed safely in Anchorage,” McGimsey says. It cost nearly $80 million to repair the damage to the plane.Such situations show just how dangerous volcanoes can be. However, volcanologists know the risks and are prepared to protect themselves.“There is certainly a higher danger level in volcanology than some other jobs,” McGimsey admits. “We understand how serious the danger is, and we don't like taking unnecessary chances. We avoid getting too close to an erupting volcano, because it's not worth injury or death simply to get a rock or a photograph.”32. Before working for the USGS, McGimsey _____.A. had been a pilot for 25 yearsB. knew nothing about the organizationC. had taught at the University of North CarolinaD. had studied at the University of Colorado33. On Dec. 15, 1989, a 747 jetliner _____.A. had all its engines restartedB. flew into a volcano in EuropeC. survived an air accident luckilyD. disappeared in a huge ash cloud34. What McGimsey says in the last paragraph shows his _____.A. prideB. carefulnessC. lonelinessD. doubt35. What would be the best title for the text?A. Game McGimsey: a man of his wordB. Game McGimsey: a volcano watcherC. The eruption of Mount RedoubtD. Lost land of the volcano第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

Who wants to share your short passage about the pollution around you?Ss: I’d like. Our earth used to be a beautiful p lace. Thick trees and green grass covered the hills and it was the best home for birds and animals. What a beautiful scene it was! However, as time went on, people destroyed the forest to grow crops. What were worse, people let their cattle eat up the grass. So you can see a stretch of wasteland instead of green hills now. As a result, when it rains, the soil is washed down the hills, strong winds blow away the rich soil that lies on the top of the fields. We do hope all the people will take good care of our forests and plant more trees to improve the environment in which we are living. I'm sure as long as we try every possible means; we're sure to have a beautiful environmentagain.T: Excellent! Thank you. Yesterday, we have talked about something about sandstorm. Today, we are going to learn more about it. Open your books on page 32. Have you previewed it?Ss: Yes.T: Very good.Step 2 pre-readingT: Now I will give you five minutes and read the whole passage quickly, find the answers to the questions on the top of this page.After 5 minutes, check the answers.T: Now, who’d like to talk about the first question? Volunteer!S1: I’d like to try. From picture I know that a sandstorm happens. It is frightening. T: Quite right. Next question? Who want to have a try?S2: There is a woman pulling a bike in a frightening sandstorm. The cyclist wears a mask and a pair of gloves. She wears a hat.T: Thank you, very well. How about next question?S3: The traffic will be very slow, because in the sandstorm there is much sand in the sky. The driver cannot see thing clearly.T: Quite right. The last one, who got the answer?S4: I think the experts advise people to stay at home and not go out. While going out, you should wear a mask.T: Thank you. Sit down please. Now, after we’ve le arnt this text, we will know how to protect ourselves, if there is a sandstorm in our city. Of course, we do not hope it happens in our city.Step 3 ReadingT: Turn your books on page 33. Look at the activity 2& 3, read the text quickly again and complete these two activities. Three minutes.★Skimming:After 3 minutes, ask some students to check the answers.
