The Triple Grown is a victory by a horse in three different races—the Kentucky Berby, the Preakness, and the Belmont Stakes—in the same racing year. The 3-year-old horse is the first horse in 37 years to win the Triple Grown. He is only the 12th Triple Grown winner in the history of horse racing.Bob Baffert, American pharoah’s trainer said, “He did great ye sterday. It was a beautiful moment.”The Triple Grown races last for five weeks on circular tracks of different lengths. The races are short, but the horses use a great amount of energy dashing to the finish line. The Belon Stakes is the last one of the races, and the longest. American pharoah led the entire race and won the race.Taking home the Triple Grown is no easy matter. The horses require many hours of training to prepare for the intense demands of racing. The raw talent and genetics of the horses also play an important role in developing winners. “Nobody can make a slow horse a fast horse.” American Pharoah owner Ahmaed Zayat said.Victor Epinoza is the jockey who rode American Pharoah. His lost his last two Triple Grown tried with different horses, but was able to bring home the prize after Saturday’s race. “I looked at that prize and I was very excited and kind of angry because two times before I couldn’t get it.” Epinoza said.Before leaving Belmont Park, American Pharoah joined photographers and fans on the grass. He posed for pictures and let people from the crowed pet him.It will be up to American Pharoah’s trainer to map out his next racing steps. “He’s an athlete. We have to keep him moving.”Said Baffert. “He’s so happy when his on that track.”24. What can we infer about the Triple Grown races from paragraph 1?A. They are really tough.B. They are world-famous.C. They are well organized.D. They are very interesting.25. What does the underline part in paragraph 4 stress?A. The importance of a horse’s trainer.B. The importance of a horse’s jockey.C. The importance of a horse’s mental ability.D. The importance of a horse’s natural ability.26. Victor Epinoza was kind of angry because ____.A. he was disappointed in his horseB. he thought the races were not fairC. he failed twice before winning the prizeD. he didn’t win the Triple Grown races.27. In the future, American Pharoah will ____.A. be a pet horseB. go on racingC. be keep in a parkD. live a happy life aloneIn a few weeks, the halls of a school in Nanuet, N. Y. will be full of mini race cars. The vehicles are carefully designed to achieve great speed.But the cars’ makers aren’t college-level engineers; they’re middle-school students attempting to learn about physics and technology. “It’s rewriting what’s possible in education,”says Vinny Garrison, the teacher who organizes the races.According to a survey, nearly three-fourths of U.S. teachers use technology to encourage students to learn. And that tech is getting smarter: students can now tour ancient worlds to learn history, take quizzes via smartphone and more. Most of the changes are designed to better prepare U.S. students for careers in fast-growing fields like science and engineering. But they can come at a cost. A $500 million plan to supply Los Angeles students with iPads was recently stopped after students found ways to avoid content filters (过滤器).So far, however, research shows that using tech in the right ways can make students smarter and more creative. Here is a look at six new technologies that are shaping the classrooms of the future.1. MakerBot has already placed more than 5,000 3-D printers in U.S. schools that are designed to help students create model cars (to learn about physics), model frogs (to learn about biology) and more.2. Publishing company McGraw-Hill’s line of digital SmartBooks quizzes students after every chapter and stresses the material they need to review; teachers can use that data to better know their students.3. Hewlett-Packard is testing touchscreen black boards in a model classroom in Taipei, which are connected with students’ individual computers, allowing them to copy notes and view multimedia (多媒体).4. Some classrooms at the University of North Carolina feature rolling desks, which allow students to easily switch from listening to a teacher to organizing into small groups.5. Instead of purchasing new tech, schools in Katy, Texas, ask kids to bring their own smartphones—so they can conduct research, answer quizzes via text and more.6. In order to help kids understand teamwork and trust, the Kickstarter-funded Empathy Toy—already used in roughly 400 schools globally—requires them to cooperate on building blocks (积木) while they are blindfolded.28.The car races are organized ____.A. to challenge college studentsB. by middle-school studentsC. for educational purposesD. at New York City Hall29. The underlined word “they” in Paragraph 3 refers to ____.A. fieldsB. changesC. careersD. students30. Which of the following is helpful for students’ practical skills?A. MakerBot.B. SmartBooks.C. Touchscreen blackboards.D. Empathy Toy.31. What’s the purpose of this text?A. To report applications of technology in schools.B. To show students’ great interest in technology.C. To describe some research work on education.D. To recommend some advanced technologies.My mother got divorced when I was 5 and was left to raise me and my two younger brothers. She didn’t have a formal education, so she had to work two full-time jobs to make ends meet.One day several years later, I was determined to help. I told the manager of the Don Carlos Motel in Nana Point that I was 15, so I could get a work permit to work as a maid.Since then, I’ve started to work alongside some of America’s top leaders, written books, and achieved financial independence. It took a lot of hard work and sacrifices.But what if I was 15 years old today? Would I be able to accomplish the same things in this new, highly competitive world with so many global challenges? It seems hard work and sacrifices aren’t enough anymore.Today, you need to be extremely adaptable. To progress in your career, it’s not enough to know one thing well. As my friend Sean Harvey, product manager at Google put it when we were speaking to student s, “Today, companies aren’t hiring people for a specific position but rather people who are smart and flexible. The way you prove that is by showing you can do multiple things well.”People need to take more risks to succeed now than ever. The combination of unemployment and slow wage growth means that we are not only at greater financial risk, but we have to take more risks to succeed.Luckily, the new Internet world of all-the-time connectedness means that anyone with a hot idea, product or service can create a business out of almost nothing. And success can be quick and big. But that success demands more “out of the box” thinking.And what about our kids? It makes me think a lot about the future that my 3-years-old daughter faces. But no matter what the future brings, I think the best message I’ll give her is to believe in herself. Life won’t get any easier, but the opportunities will come—as they always have—to those who work hard, adapt as they need to, and trust their abilities.32. We can infer that the author had ____.A. a difficult childhoodB. a lonely childhoodC. a normal childhoodD. a happy childhood33. What advice did Sean Harvey give students?A. To focus on their majors.B. To make progress every day.C. To get used to new situations quickly.D. To do multiple things at the same time.34. Compared to the past, people who want to succeed now need ____.A. more timeB. to be more creativeC. to work harderD. more money35. The author writes the text mainly to ____.A. describe her childhoodB. tell a story about her motherC. share some useful parenting skillsD. give some suggestions about success第二节: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,选项中有两项为多余选项。

Mozart’s “Flute Concerto No.1 in G Major” is most often associated with bright yellow and orange, whereas his “Requiem in D Minor” is linked to bluish gray, the findings revealed.US researchers from the University of California, Berkeley, enlisted nearly 100 subjects for a study on music and color. With 37 colors, the UC Berkeley study found that people tend to pair faster-paced music in a major key with lighter, morevivid, yellow colors, whereas slower-paced music in a minor key is more likely to be teamed up with darker, grayer, bluer colors.“Surprisingly, we can predict with 95 percent accuracy how happy or sad the colorspeople pick will be based on how happy or sad the music is that they are listening to,” said lead author and UC Berkeley vision scientist Stephen Palmer.In three experiments, the subjects listened to 18 classical music pieces that varied in pace (slow, medium, fast) and in major VS minor keys. In the first experiment, participants were asked to pick five of the 37 colors that best matched the music to which they were listening. Separately, they rated each piece of music on a scale of happy to sad, strong to weak, lively to dull, and calm to angry.Next, the research team plans to study participants in Turkey where traditional music employs a wider range of scales than just major and minor. “We know that in Mexico and the US the responses are very similar,” Palmer said. “But we don’t yet know about China or Turkey.”21.What can we know about Mozart’s “Flute Concerto No. 1 G Major”?A. It is fast in pace. B It is slow in pace.C. It makes us feel upset. D It makes us feel optimistic.22. What did the US researchers find from the result of the new study?A. There are colors that do not match any music.B. People tend to connect happy colors to slow-paced musicC. There is a one-to-one connection between music and color.D. People nearly do the same in picking colors for different music.23. How did the researchers do the research?A. By making predictions.B. By researching journals.C. By conducting experiments.D. By studying famous musicians.24.According to the text, the research mainly deals with __________A. how colors or music influence our emotionsB. how emotions affect music-color connectionsC. why we have different feelings towards musicD. why we have different feelings towards colorsBTaj Mahal, Agra, IndiaAs many as 28 different varieties of precious stones were used to decorate the outside of the Taj Mahal. Construction took around 20 years. The building, which was made from white marble from the quarries(采石场) of Rajasthan, appears pink in the morning, white in the day and golden in the moonlight.Akashi Kaikyo Bridge, Akashi Strait, JapanIt took 10 years to construct the Akashi Kaikyo Bridge. It connects the city of Kobe, on Japan’s mainland, with Iwaya on Awaji Island. Before it opened, the only way to get between the two cities was by ferry. However, the waterway was at the mercy of severe storms and when two ferries overturned in 1955, killing 168 people, public anger convinced the government of the need for a bridge. It's the longest suspension bridge in the world, with a length of 1,991 meters.Panama Canal, PanamaMore than 4. 5 million cubic yards of concrete were used in the construction of this canal’s locks and dams. The Panama Canal is a 47-mile long waterway that connects the Atlantic and Pacific Oceans. The earth and rubble dug to make way for it was enough to bury Manhattan to a depth of four meters. A series of locks allows ships to pass through the water. Each lock door weighs 750 tons and each lock fills with 52 million gallons of water to accommodate the 15,000 ships that use the canal every year.Grand Canyon Skywalk, ArizonaThe Skywalk’s foundation is strong enough to support 71 million pounds , Located1,219 meters above the Colorado River, the Grand Canyon's Sky Walk consists of one million pounds of steel and 83,000 pounds of glass. It was the creation of Las Vegas businessman David Jin, who approached the Hualapai Tribe with the idea of a glass walkway over the Grand Canyon in 1996. The Sky walk was assembled on site.25.The Japanese government decided to build the Akashi Kaikyo Bridge ___________A in the year of 1955B following public opinionC to show its national powerD to develop Japan’s economy26.The Grand Canyon Skywalk is probably a real challenge for those who __________A are airsickB hate rock climbingC have a fear of heightD feel ill traveling in boat27.In which section of a book can the text probably be seen?A. ScienceB. AgricultureC. TechnologyD. GeographyCI am an English dictionary. I can still remember the day my ex-owner bought me. He had stood in front of the shelf for around half an hour before finally picking me. Originally, he chose my neighbor. But because she had some ink on the cover, he put her down and chose me instead.I may sound arrogant (傲慢的) . But please forgive me. I am so proud of my vocabulary. With 100,000 entries and 300,000 examples, I think no scholar can be more knowledgeable than me. My only weakness is that I can’t speak. But that is not my fault. Iwas not designed to speak in the first place. My ex-owner was supposed to read the phonetic symbols (音标) clearly printed beside each word, which were also my selling point. I should have been respected but have ended up lying next to a piece of used toilet paper inside the rubbish bin.It is all because of the electronic dictionary. He is the bad guy because he takes advantage of my one weakness. And I just don’t understand why he can be so slim. He also has about 100,000entries but 450,000 examples! But I know this was not the reason why my ex-owner was attracted, for he was not a very diligent (勤奋的) student and seldom read the examples listed. The main reason was that the bad guy had so many games in him. My ex-owner always pretended to be working hard while actually he was playing games.My ex-owner put me on his bookshelf because of my awesome English name “Advanced English Dictionary”. He wanted people to think that he was an advanced learner. I wanted to tell him that it would be better if he hid the comic books standing next to me. But, you know, I can’t speak. I stood there for years. I was so bored. So I talked to the comic book next to me. Under normal circumstances, I wouldn’t have talked to him because I was educated and he was not. But who else could I choose? He told me that my ex-owner had read him once only and then puthim there. I was upset because he had never read me from page one to page 1,000. Was I not a better book than the comic book? I wanted to challenge his honesty but before I did so, he was thrown away.I give up. My pages are absorbing waste water. There is no way people will use me again. Suddenly, I want to talk to the comic book. Would he talk to me if we met?28. Why does the dictionary think that the electronic dictionary is the “bad guy”?A. I t contains more words and examples.B. It can actually pronounce the words.C. It has a smaller size.D. It has not many games.29. The dictionary thinks that its ex-owner put it on the bookshelf because he ______.A. thought that it could match the comic booksB. wanted his friends to study EnglishC. just wanted to show offD. had to use it sometimes30. What was the dictionary’s attitude toward the comic book standing next to it?A. It wanted to make friends with him.B. It respected him.C. It envied him.D. It hated him.31. Which of the following is the best title for the text?A. A Dictionary Is Replaced with an Electronic OneB. Students Seldom Use DictionariesC. A Dictionary and a Comic BookD. The Experience of a DictionaryDWitchcraft(巫术)was not made a capital offence in Britain until 1563 though it was disapproved by Pope Innocent VIII in 1484. From 1484 until around 1750, some 200,000 witches(女巫)were burnt or hanged in Western Europe.Most supposed witches were usually old women, and always poor. Any who were unfortunate enough to be an old woman with broken teeth, sunken cheeks and sockets and a hairy lip were assumed to possess the “Evil Eye”. It was more the case if they also had a cat. Many unfortunate women were taken away on this sort of evidence and hanged.Witch fever held East Anglia for 14 terrible months between 1645—1646. A man called Matthew Hopkins, an unsuccessful lawyer, contributed a lot! He became known as the “Witchfinder General”. He had 68 people put to death in Bury St. Edmunds alone, and 19 hanged at Chelmsfor in a single day. After Chelmsford he set off for other countries. Much of Matthew Hopkins theories of telling a witch were based on Devil’s Marks. He took a small mark to be a Devil’s Mark and he used his “needle”to see if these marks were insensitive to pain. His “needle” was basically a trick so the unfortunate women never felt any pain.There were other tests for witches. Mary Sutton of Bedford was put to the swimming test. With her thumbs tied to opposite big toes she was thrown into the river. If she floated she was guilty; if she sank, innocent. Poor Mary floated!Though many of the acts against witchcraft were put to an end in 1736, witch hunting still went on. In 1863, a suspected male witch was drowned in a pond in Headingham, Essex and 1945 the body of an elderly farm laborer was found near the village of Meon Hill in Warwickshire. His throat had been cut and his body was pinned to the earth. The murder remains unsolved; however, the man was said, locally, to be a male witch. It seems that belief in witchcraft has not entirely died out.32.A female witch was often found to be ________A. a young ladyB. a lucky womanC. an ugly womanD. a blind girl33. Matthew Hopkins can be best described as __________A. kind and smartB. tricky and mercilessC. successful and niceD. famous and fortunate34. Why did people throw Mary into the river?A. To take her life.B. To tell if she was a witchC. To test her swimming skills.D. To prove that she was guilty35. What’s the main idea of the last paragraph?A. Witches are still badly treated all over the world.B. Witches were terribly treated in the European history.C. Some people still have been using magic in daily lives.D. There have always been people believing in witchcraft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,选项中有两项为多余选项。
