山西省45校2018届高三第一次联考英语试题
山西省45校2018届高三第一次联考英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读选择One of the best student cities: BostonBoston, Massachusetts is the unofficial student capital of the United States. The greater Boston area contains some of the most famous universities in the world，including Harvard and the Massachusetts Institute of Technology (MIT). With their reputation attracting some of the brightest students from around the globe, the heart of New England is young, energetic and active.Best spotsThe Fenway area — home of the Boston Red Sox baseball team — attracts students from nearby schools. On game days, the neighbo rhood’s many sports bars are packed with college students.The Harvard Square is also a popular gathering spot for Harvard and MIT students, with several restaurants serving up affordable and tasty food.Student activitiesBoston’s most popular college events are the universities’ annual music festivals — like Yardfest at Harvard and Spring Fling at Tufts University — during which big-name stars perform free concerts before the spring semester ends.The Berklee College of Music, which attracts top international talent and counts the band Passion Pit among its alumni (男校友), often organizes free student performances in such picture-perfect locations as the Boston Harbor National Park. The free-to-watch boating races on the Charles River are also well-attended on fair-weather race days, when students cheer on their classmates.Student discountsThe Museum of Fine Arts, one of Boston ’ s leading cultural institutions, is free for students carrying ID from one of the many schools in the city and the museum’s speci al exhibits and film screenings are discounted for students.The historic Isabella Stewart Gardner Museum and the New England Aquarium offer discounts for all university students, while admission to Harvard’s museum is free for Harvard students and discounted for all other college kids. Even movie theatres like Regal CinemasFenway and AMC Loews Boston Common cut students a discount.1．The underlined part “the heart of New England” in paragraph one refers to . A．Boston B．MassachusettsC．Harvard D．the MIT2．The Fenway area most probably attracts students who have interest in .A．food B．sportsC．music D．science3．We learn from the text that the Berklee College of Music .A．often gives free performancesB．often invites big stars to performC．organises performances along the Charles RiverD．attracts talented teachers such as the Passion Pit members4．Which of the following is free for students carrying ID from one of the schools in Boston? A．The Isabella Stewart Gardner Museum.B．The New England Aquarium.C．The Museum of Fine Arts.D．Regal Cinemas Fenway.Known as “wolf girl” at her West Warwick, R.I., school, Alyssa Grayson has spent much of her young life teaching others to protect and respect animals. After starting a wolf club in second grade, Alyssa learned all she could about her favorite animals. Today, she gives presentations about protecting wolves at libraries and schools —she’s even spoken at a university. In fact, she’s become such a wolf expert that she was appointed as the fir st junior advisor to the National Wolfwatcher Coalition.When she’s not teaching others about wolves, Alyssa can be found volunteering at her local animal shelter, taking care of dogs and cats. She’s also trained as a citizen scientist for Frog Watch USA．In short, Alyssa Grayson proves that you are never too young to make a difference for animals.When asked how she got interested in saving wolves, Alyssa says, “I’ve loved wolves since I saw them in a movie when I was 2 or 3 years old. Then one day I saw a commercial about wolf hunting. I asked my mother why people do this, and she told me because people don’t like wolves. I decided from then that I wanted to save wolves.”Today, wolves are hunted, trapped, or poisoned. Hunters chase wolves for miles in an airplane until the wolves are too exhausted to run anymore. Then they shoot them. The animal doesn’t have a chance to escape. Animals are also trapped for their fur. They are left to suffer in a trap with no food, water, or shelter. Alyssa thinks the fur looks better on the animal in the wild, where it’s meant to be, than on a human.Alyssa believes wolves are important to our worlds. She says, “Wolves are an apex predator, which means they are at the top of the food chain. Removing them from the ecosystem is a big mistake. The ecosystem is like a chain of dominoes (多米诺骨牌)—with the apex predator as the one in front. If you were to knock down that domino, the rest of the chain would go down too.”People usually think of “the Big Bad Wolf” when they hear about wolves. However, Alyssa says, “If they would base their thoughts on facts, not fairy tales, we wouldn’t have people wanting to kill wolves.”5．Alyssa is known as “wolf girl” at her school because .A．she keeps wolves as petsB．she was raised by wolvesC．she does a lot to protect wolvesD．she started a wolf club at her school6．According to the first and second paragraphs, Alyssa .A．gained knowledge about wolves at librariesB．cares about other animals besides wolvesC．started to give presentations since second gradeD．is the first junior citizen scientist for Frog Watch USA7．Paragraph four is mainly about .A．why wolves are killedB．why wolves are trappedC．the tools used to hunt wolvesD．how wolves are treated8．From the last paragraph we can infer that Alyssa .A．doesn’t need fairy talesB．doesn’t believe in fairy talesC．encourages people to find out the facts about wolvesD．believes that more people will work to save wolvesThe value of the U.S. penny has been dropping for years. Many countries have stopped using pennies. Is it time for the U.S. to do the same?Those who think we should keep the U.S. penny offer the following arguments to support their positions:Prices will increase. If we get rid of the penny, everything will have to be rounded to the nickel (五分硬币), costing us more for everything we buy.Charities need pennies. There are thousands of small charities that depend on pennies to bring in donations. People think nothing of pouring out their old penny jars to support charity, but they won’t part with nickels so easily.Nickels cost even more to make. If we get rid of the penny, we will need more nickels in circulation. Nickels cost 7.7 cents to make, 2.7 cents over face value, as opposed to 0.26 cents over face value to make a penny. Since the penny costs 0.26 more than face value to make, the Mint (铸币厂) can make 5 pennies and still lose less money than making 1 nickel.People who want to retire the penny also have some persuasive arguments, including these:Pennies waste time. The average American wastes 2.4 hours a year handling pennies, or waiting for people who handle them. This statistics is the result of collecting a number of penny-handling related events, including the 30-second period we sometimes spend waiting for someone who just has to dig through their pockets or purse to find that last cent so they can pay for something with exact change (probably so they don’t get stuck with any more pennies).Making pennies wastes taxpayers’ mo ney. It costs the U.S. Mint 1.26 cents to make each 1 cent coin, meaning that taxpayers are losing 0.26 of a cent for each one of the 7.4 billion pennies the Mint produces each year.History will repeat itself. In 1857, the Mint stopped making the half-cent coin, partly because the cost of making it was considered to be no longer needed. Yet, commerce continued without any catastrophic effects. History has shown us that updating the monetary supply in countries where the currency (货币) is very stable has had little, if any, negative effect on the economy, or on people’s acceptance of the coinage.9．According to people who want to keep the penny, getting rid of the penny .A．is good for ordinary consumersB．is especially bad for rich peopleC．will be convenient for themD．may lead to fewer donations to small charities10．Why do pennies waste time?A．Because consumers don’t always have enough change.B．Because it takes time for people to get them from their pockets or purse.C．Because pennies are not easy to take.D．Because pennies are difficult to collect.11．The underlined word “catastrophic” in the last paragraph can be replaced by “”. A．direct B．positiveC．important D．disastrous12．The text is mainly developed by .A．giving examplesB．setting down general rulesC．comparing different opinionsD．following the natural time orderToday we think of Abraham Lincoln as a great leader. What most of us don’t know is that he was a well-known humorist and storyteller in his day.Lincoln learned to tell jokes and stories from his father. When Lincoln became a lawyer, he used his jokes and stories to gain the good will of the jury (陪审团), and more than once his opposing lawyer would complain to the judge that Lincoln’s stories were irrelevant and distracting (转移、分心) to the jury. The trouble for them was that Judge David Davis loved Lincoln’s jokes more than anyone else in the court room.As a politician, Lincoln made excellent use of his humorous stories. His long time political opponent Stephen A．Douglas complained that “Nothing else — not any of his arguments or any of his replies to my questions — disturbs me. But when he begins to tell a story, I feel that I am to be overmatched.” More than once Douglas and other political opponents of Lincoln’s saw their well presented arguments forgotten by the audience after Lincoln followed up their speeches with a homely story.As the responsibilities of the office of President became greater and heavier, Lincoln used humor to find relief. He wanted to reduce the stresses in himself and those around him. One ofLincoln’s neighbors told that one day, he saw Lincoln walking past with two young shouting boys. “What’s the matter, Mr. Lincoln?” the neighbor asked. “The same thing that’s the matter with the whole w orld,” Lincoln answered. “I have three walnuts, and each one of them wants two of them.”One cannot truly appreciate Lincoln without understanding his humorous side. He used his jokes and stories both for the purpose of winning over his audience and relieving the pressure he experienced as President during the terrible Civil War.13．When Lincoln was a lawyer, what was his purpose of telling jokes and stories?A．He wanted to satisfy the judge’s desire for jokes.B．He wanted to distract his opposing lawyer.C．He wanted to relieve his pressure.D．He wanted to impress the jury.14．What might be Douglas’ attitude towards Lincoln’s humorous stories? A．Appreciative. B．Annoyed.C．Concerned. D．Surprised.15．What’s the purpose of the text?A．To educate. B．To inform.C．To persuade. D．To entertain.二、七选五How to drive greenerBuying green can produce great benefits and so can small changes in your driving behavior. 16．1. Avoid aggressive driving. Sudden starts and aggressive driving can waste your gas. 17．That’s beca use just one second of high-powered driving can produce the same level of CO as 30 minutes of normal driving.2. 18．A lot of us like to push the speedometer up to 75 miles per hour on the highway. However, slowing down to 65 miles per hour can increase your fuel economy by up to 10 percent and reduce the amount of pollution coming from your car.3. Plan ahead. When possible, plan your trips to avoid the stop-and-go of rush hour. And remember to pack all of your tasks into one trip since a warmed-up engine produces fewer emissions (排放物).4.Pay attention at the gas station. Don’t overfill your gas tank or try to top it off because spilled (溢出) gas changes into mixture of fog and smoke and can pollute groundwater. When you are finished filling up, be sure you tighten your gas cap. 19．5.Park smart. Parking your car in the shade not only helps you avoid feeling very hot in your car, but it helps minimize evaporation (蒸发) of fuel.20．By walking, cycling or public transport, you will make a big difference for our planet. Leave your car at home just two days a week. And you will help cut greenhouse gas emissions by 1,500 pounds a year.A．Change the oil.B．Slow down.C．Leave your car at home.D．And this type of driving behavior adds to pollution.E.In this way you can save as much as 30 gallons a year.F.The following advice can help you save gas and contribute to the well-being of our planet.G.Parking in your garage when possible to cut down on summer heat and keep off frost in the winter.三、完形填空In elementary school, I was living with my parents and my brother in a rented apartment in New York City. At the time, I never thought of myself as comfortable or 21 —it was just the way life was.Everything 22 before I started the sixth grade. Our landlord (房东) kicked us out 23 notice. My family had to 24 to the Life Family Shelter. We had a private room to sleep in at the shelter, which housed 90 25 , but it was a quarter of the size of our26 living space, so we always 27 crowded.I didn’t fully understand what was happening, but after a few weeks, it 28 sank in: I was homeless. I felt so 29 that I didn’t tell anyone at school. I felt like I could never truly be myself and open up to friends, because I carried around this secret. It was a 30 time.The only good part about living in the shelter was that I got to go to a(n) 31 program that was run by the Coalition for the Homeless. It was a quiet place where I could do my 32 or arts.After three years, my parents finally 33 affordable housing. I was so excited. We have two bedrooms and one bathroom that we don’t have to 34 with strangers. It’s so nice to have 35 again. It’s funny —you don’t realize how valuable something is until you are 36 to live without it.Last April, I started feeling different about my 37 being homeless. For the first time, I didn’t feel ashamed. I decided that it was time to tell my 38 Jason. He was shocked. 39 , he was suppo rtive and didn’t treat me any differently.I also started volunteering at the after-school program because I want to help other kids who are 40 the same thing as I did.21．A．curious B．unafraid C．happy D．confident 22．A．happened B．changed C．appeared D．exchanged 23．A．without B．along C．within D．beyond 24．A．occur B．appeal C．belong D．move 25．A．families B．classes C．teams D．grades 26．A．new B．simple C．small D．old 27．A．seemed B．felt C．looked D．became 28．A．gradually B．really C．immediately D．finally 29．A．tired B．confused C．embarrassed D．surprised 30．A．lonely B．guilty C．slow D．quiet 31．A．adventurous B．after-school C．real-life D．personal 32．A．homework B．job C．dream D．housework 33．A．recognized B．created C．found D．explored 34．A．agree B．communicate C．share D．compete 35．A．freedom B．wealth C．fame D．privacy 36．A．forced B．attracted C．persuaded D．ordered 37．A．story B．background C．experience D．introduction 38．A．father B．brother C．relative D．friend 39．A．However B．Therefore C．After all D．Moreover 40．A．seeing through B．going through C．going around D．looking through四、用单词的适当形式完成短文阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式（不多于3个）。

I had never been to such an amazing national park before, yet I wasn’t the most athletic person so I knew that I couldn’t stick through all the hiking up and down. It actually ended up being a fun and adventurous experience.The ride there was definitely long but worth it. As I woke up from my nap, I saw the beautiful scenery of the tall mountains and beautiful streams. The trails were made nicelyfor visitors. The waterfalls were breathtaking. Climbing up rocks was one of my favorite parts. Even though I fell a couple of times, I still have a lot of fun. The fact that my family and I spent so much time together all trying to find out which route to take and what views to watch really brought us closer together.The great thing about nature is that, it’s just you, the views, and the people around you. There’s nothing there to bother you and it’s the best way to relax and enjoy yourself. Yosemite has 5 of the world’s highest waterfalls, and about 300 lakes. The structure of each mountain is incredible; it’s formed in ways that almost take your breath away. Some of them are of a deep dark color with waterfalls forming; some are formed with spots of green peeking (窥探) out. It’s definitely something you wouldn’t want to miss.Yosemite isn’t the only great National Park but based on my experience I highly recommend going out and enjoying nature with family and friends. It’s a great time to bond, laugh, and take in what Mother Nature offers.24. The author writes the first paragraph mainly to _____.A. introduce the topic of this passageB. offer an example to usC. tell us his future plan for hikingD. describe a national park25. While climbing up rocks, the author was _____.A. nerve-rackingB. injuredC. pleasedD. worried26. According to the passage, Yosemite _____.A. is crowded with visitors every dayB. is the only great National ParkC. is worth travelling toD. is nothing but a common destination27. The author suggests us _____.A. keeping a good bond with other peopleB. visiting Yosemite now and thenC. trying to protect the environmentD. going out to enjoy the beauty of natureCWhat are the chances of a 100-year-old chocolate candy falling in your treat bag this Halloween? Though Goo GooClusters may not be as familiar as Kit Kat or Hershey bars, people of all ages have enjoyed it for an entire century.In 1901, a 19-year-old named Howell Campbell opened a candy store in Nashville, Tennessee. He made all kinds of sweets and hard candies with just two copper kettles and about a dozen employees. Then, in 1912, he made the first candy to combine chocolate with other ingredients such as caramel, marshmallow, nougat, and peanuts. Originally, these clusters were hand-wrapped and sold under the counter at a few local stores with a sign reading,“A nourishing (滋养的) lunch for a nickel.” Now, they are known as Goo Goo Clusters.What else makes a Goo Goo so special?“In addition to it being the very first-ever combination confection created, its shape also makes it quite unique,’’ says Beth Sachan, Goo Goo Clusters’ senior marketing manager.“The Goo Goo Cluster is a big, imperfectly round mound (垛) of deli ciousness!”The 100th anniversary of the Goo Goo Cluster is being celebrated throughout the month of October, the biggest candy-selling month of the year. About 40 restaurants in theNashville area have created unique desserts inspired by GooGoo Clusters to serve to their customers.Additionally, a Goo Goo-sponsored race called the “Jog’n Hog” was held in Nashville on October 13. Adultsand children ran three miles to the finish line after eatingat least one of six Goo Goo Clusters from a bag they were given at the halfway point. A golden Goo Goo was hidden inone of the bags. The winner received a $100 gift certificateto the candy’s website, googoo. com.28. We can learn from the first paragraph that Goo Goo Clusters _____.A. have been popular with the customersB. willbe sold out by this HalloweenC. look like Kit Kat and Hershey barsD. are much better than other candies29. The underlined word “confection” probably means _____.A. ingredientB. candyC. foodD. deliciousness30. The customers would like to enjoy Goo Goo Clusters probably because of _____.A. its weight and combinationB. itspackage and designC. its fair price and low costD. its shape and deliciousness31. The 100th anniversary of the Goo Goo Cluster is being celebrated by _____.A. offering specially designed dessertsB. giving away many gift certificatesC. opening a lot of restaurantsD. holding a competition of eating candiesDLove to sink into your chairs and relax when you get to school? Then you will not be happy to hear that schools all over the world are seriously considering exchanging traditional desks for ones with no seats at all —Yes, that means you will be encouraged to stand through those already too long math and science lessons! Why would anyone even think of putting kids to such cruelty? Experts say it improves their health and helps fight obesity. While that may seem a little far-fetched (牵强的) the officials at the few schools around the world seem to agree.Among them are educators from the College StationIndependent School District in Texas, who recently completed a week-long experiment involving 480 students across three elementary schools. The 374 kids that agreed to participate in the study were provided a device that helped record step count and calorie consumption over the entire period.All 25 teachers involved in the study reported that students appeared to be more alert and concentrate better, when allowed to stand. The one thing that did surprise the researchers was that younger kids were more willing to stay standing than kids in higher grades. They believe this may have something to do with the fact that after years of being asked to “sit still”, older kids have a harder time adjusting to this unexpected freedom.American schools are not the only ones reporting success with stand-up desks. Four Catholic schools in Perth, Australia, which have been testing them since October 2018, have seen similar results. In May 2018, Grove House Primary School in Bradford, West Yorkshire, became Europe’s first test one, with a seven-week trial that involved the use of desks made by Ergotron in their fifth-grade classrooms. While official results are not out yet, early reactions fromboth teachers and students, have been extremely encouraging.The findings of these studies and others done previously, all seem to mean that allowing kids to move around in classrooms is a win-win for students and teachers —it helps kids get healthier and provides educators with a more engaged audience.32.
