Larry fell to the ground. Less than a minute later, Tom Alguire passed by on his bicycle. He caught sight of a man lying on the roadside, so he jumped off his bike and ran over. He recognized Larry immediately, because he had been Larry’s doctor for nearly 20 years. Dr. Tom felt for a pulse (脉搏) at first. Finding none, he began to give Larry first aid. It wouldn’t restart Larry’s heart, but it would keep the blood flowing until someone else arrived. Tom could only hope someone would come by soon, around six o’clock in the morning on a holiday weekend. Tom couldn’t stop pressing Larry’s chest to run for help — Larry’s brain cells would die without the blood. And Tom didn’t have a cell phone with him. Soon, a car did drive by. But the driver ignored Tom’s appeal for help. What was he going to do? Tom was very worried. Finally, another car came down the road, driven by Michael Saliot, a U.S. Coast Guard Officer. Michael wasn’t one to miss a chance to help a person in need. He quickly dialed 911. Doctors then found that Larry had suffered a heart attack and there were severe blockages in two of Larry’s major arteries (动脉). Only the timely arrival of Dr. Tom saved his life. How did Dr. Tom happen to be bicycling that morning, down that quiet street? It turned out that as Tom rode, his bike chain fell off. He spent about eight minutes fitting it back; otherwise, he would have seen nothing of Larry’s problem. 25. Doctor Tom gave Larry first aid in order to _____. A. keep Larry’s blood flowing B. wake up Larry C. restart Larry’s pulse D. stop Larry from bleeding 26. Why didn’t Tom call 911 for help? A. He didn’t take a cell phone with him. B. He was waiting for someone else for help. C. He was so nervous that he forgot to do it. D. He couldn’t stop pressing Larry’s chest. 27. Which of the following is TRUE according to the text? A. Tom Alguire saw Larry before Larry fell to the ground. B. Larry Ritsema went to work early on foot that morning. C. Tom fitted his bike chain back after Larry was sent to hospital. D. Michael Saliot was a man always ready to help others. C China which boasts 4 inventions in ancient times, has once again shown its ability to change the world with its" new four great inventions" :high-speed railways, electronic payments, shared bicycles and online shopping. "The new great inventions are all related to China's high technologies, which improved the quality of people's lives." said Wu Hao, executive director of the BRRI. "It is increasingly clear that China is innovative and is leading in many ways such as social messaging app WeChat, "said Rebecca Fannin, founder and editor of Silicon Dragon. The new four innovative ways of life were most appealing to youths from 20 countries participating in the Belt and Road Initiative, according to a survey by the Belt and Road Research Institute of Beijing Foreign Studies University. "My wallet is no longer in use. I can buy and eat whatever I want simply with a tap of my phone," said Lin Jinlong, an overseas Chinese student from Cambodia, adding that. "even pancake sellers are using Alipay". "I can order food at home in China, which is super convenient. If I were at home in Cambodia, I would have to go outdoors." "The trip from Beijing to the coastal city of Tianjin is more than 100 km. You can't imagine how fast it takes if you travel by Chinese high-speed train, It will take only half an hour. But in Cambodia, which has only two railways, the traveling time of the same distance will be increased to 6 times," said Lin. "China has entered a new period," said Bernhard Schwart lander, World Health Organization Representative in China. As a huge fan of bicycles, Bernhard expressed his affection for China's shared bicycles, saying that "shared bikes are bringing cycling back to people's lives and they are making public transport more attractive and. convenient, and encouraging people to be more active." 28.What does the underlined word "innovative" in Paragraph 2 probably mean? A. Convenient. B. Expensive. C. Popular. D. Creative. 29.What do we know from Lin Jinlong's words? A. Food can be ordered by cell phones in Cambodian. B.

Wallets can be replaced by cell phones both in China and Cambodia. 30.Which invention impressed Bernhard most? A. High-speed railways. B. Electronic payments. C. Online shopping. D. Shared bicycles. 31:What is the main purpose of the passage? A. To compare old and new four Chinese great inventions. B. To show how four Chinese new inventions impressed the world. C. To present a Cambodian student's living experience in China. D. To introduce benefits of popular means of transportation. D CHICAGO--- Airplanes are polluters. They're as noisy as a rock concert, and send out poisons into the air as well as dump millions of pounds of carbon dioxide into the atmosphere every year. By 2050, emissions (排放) from planes are expected to become one of the largest contributors to global warming. That’s why researchers at MIT are designing a completely new type of airplane for NASA that will enable greener airplanes to take flight before 2050. The 180-passenger D “double bubble” series was designed to replace the Boeing 737 class aircraft, the most popular jetliner in the world right now. The design is called a “double bubble” because it uses two partial cylinders (气缸) placed side by side. Those two cylinders create a wider structure that looks like two soap bubbles joined together. In today’s commercial airplanes, air flows directly into the engines located on the plane’s wings. That high-speed air flow drags on the plane, and requires more fuel to overcome the design inefficiency. MIT’s design changes all that. By moving the engines to the plane’s tail, they take in slower moving air present in the wake of the fuselage (机舱). Less drag means less fuel is needed to get the plane the same distance. Burning less fuel can help passengers’ wallet as well as the environment. The environmental implications of saving energy are as just as clear: the fewer emissions that planes spout(喷射) into the atmosphere, the healthier our planet. But for passengers, we still have a couple decades to wait before any of these planes make it onto the runway. NASA’s goal is to make sure the planes that MIT has designed can take off by 2035. 32. The best feature of the double bubble flight is that _____. A. it will make no noise B. it will hold more passengers C. it is designed to save fuel D. it needs no runways to take off 33. Which of the following is NOT true according to the text? A. It's expected that NASA’s goal will be realized by the year 2035. B. Airplanes are very noisy for the environment C. MIT’s new design will save passengers’ money D. Emission from planes are contributing the most to the global warming now. 34. What’s the main idea of the text? A. Here is Boeing 737's end B. Passengers will enjoy lower prices C. Researchers are designing greener aircraft D. Airlines attract passengers with new planes 35. The passage comes from a ____. A. Science textbook B. News report C. Travel guide D. Environment research 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。 Ways to Conquer Fear Life can be scary.

I am writing to apply for the position you advertised on the Website. First of all, having studied English for about ten years, I have good command of English. With fluent oral English, I’m convinced that I have no difficulty in communicating with foreign guests. Furthermore, since I grow up here, I’m familiar with the history and traditions of Yunnan Province. And I have a strong affection for them. More importantly, considered as a kind, confident and outgoing boy/ girl, I can make friends with different people in no time. I am sure foreign visitors will be satisfied with my thoughtful and excellent service. I would deeply appreciate it if you could give me the precious chance to serve as an interpreter. Looking forward to your early reply. Yours sincerely, Li Hua 录音原文 Text 1 M: Laura, are you going to Sophia’s end-of-school party? W: Oh, no! I forgot all about it, Matt. She has one every June, doesn’t she? I missed the last one. M: It’s a lot of fun. You should really come! Text 2 M: Ms. Anthony, this homework is really difficult. Can you give us some help with the answers? W: No, but I’ll allow you to work in groups this time. Then one person from each group will present the answers to the class in the end. Text 3 W: Sometimes I just wish I were a flower. Look at them getting watered over there…it looks so refreshing! And we’re here sweating in gym class while Mr. Filbert makes us run like the wind! M: I’d rather be a dog, taking a nap in the shade and beating the heat! Text 4 W: Where have you been? It is a long time since I saw you last month at the company’s dinner party. Have you been away on business? M: No, I’ve been away on holiday. My uncle and aunt live in London. I visited them. Text 5 W: Tom, I heard you guys study by groups. How big is your study group? M: Well, there were 8 of us to begin with. Then 3 students left. Text 6 W: Look around us. Almost everyone is sitting at their tables using their cell phones. M: I never even noticed. W: That’s my point. You didn’t notice, because you’re so used to it. M: I’m hungry. What should we get to eat? W: Look at this. We don’t even have to speak to the waitress to order our food. We just select what we want from this electronic tablet. M: Cool! Let me see that. W: I think all this fancy technology is turning us into robots. People don’t even communicate in person anymore. Something is wrong with this society. M: Cool! You can play a game on this thing! W: John? M: Hold on…Yes! A new high score! Sorry, what were you saying? W: Never mind. Text 7 M: It’s raining again. Time to fix up the backyard garden. I need to pull the weeds out. And tonight, the temperature will be close to freezing. I’ll have to cover the plants so they don’t die. W: That’s a lot of work! My garden doesn’t need so much care. M: I didn’t know you had one. Where is it? W: In my kitchen. I put all my plants by the kitchen window. They get plenty of sunshine, and I remember to water them often. If they were out on the balcony, I would probably forget. M: What do you grow? W: I have some herbs and two different kinds of hot pepper plants. I use these in my cooking. I also have some plants with flowers, just for decoration. M: Our gardens are very different. I have many vegetables and some small fruit trees. Text 8 M: What is this book here? I recognize some of the words, but I’ve never seen most of them before. W: That’s not mine. It is my sister’s. She is taking a French class. M: I didn’t know the two languages were so similar. W: Oh, yes. English borrows a lot of words from French, Spanish, and even German. M: Really? Can you give me some examples? W: Restaurant, menu, chef, salad…those are all French words. They are pronounced differently in French, though. M: I never knew that. What else? W: Let me think…well, mosquito and cockroach are Spanish words, as are many city names in America. M: So English is really just a mix of a bunch of other languages? W: I guess you could say that. M: Language learning is such an interesting thing! Can you teach me some words after school every day? W: Okay. Text 9 M: Sandra, I bought you a gift for your birthday. W: Alan, you know we don’t buy gifts for each other anymore. That’s what our children and grandchildren are for — giving presents! M: I know, I know… but I couldn’t pass this up. It’s a ticket to the horse races in Shanghai. W: What? M: Yeah! I know you’ve been wanting to go, ever since the international event came to China in 2014. I was too late to buy tickets before they sold out in 2016. Now it’s 2018, and it’s time you got your wish! W: This is such a nice surprise! Thank you, my dear! I never would have guessed you’d do something like this! You hate fancy events like this. M: Oh, I do. That’s why I’m not going. You wouldn’t have fun with me there, either. I would just be complaining the whole time. W: But I can’t go alone… M: That’s why you’re going with your sister Anne. I bought a ticket for her, too. You ladies will have a great time. W: A double surprise! I can’t wait to tell her! She loves watching the competitions on TV. What a wonderful gift from my thoughtful husband! Text 10 W: Fellow scientists, I finally have some good news to report. As you know, I have been studying sea life for three months in New York Harbor. Today, I can finally present some hard evidence that sharks have returned to these waters. For the past two weeks, I’ve been helping to film the Shark Week program for the Discovery Channel on TV. My job was to sit in a boat near a dead whale and check it for shark bites. It’s been a very hot July, so this wasn’t the easiest task. After five days, I noticed there were several large shark bites along the stomach of the whale. I was thrilled! Because this means our conservation efforts are starting to pay off. Sharks returning to a former hunting ground indicates that the waters are cleaner and healthier. We have been trying to clean up this area and the rivers that poured into the harbor for many years. I want to take this opportunity to thank the Friends of the Environment Society. You have all made your best effort so that future generations can live in a clean world.查看更多
