2019-2020学年长春市汽车区第四中学高三英语三模试题及答案解析
2019-2020学年长春市汽车区第四中学高三英语三模试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AAlex Palmer says he'll never forget his 13th birthday, not because of a gift or a party, but fire. “It made me realize how valuable life is,” said Alex, a seventh grader atMonroeDemonstrationSchoolinTulsa,Oklahoma.On April 18, Alex and many other kids from his school were riding home on a school bus when they suddenly saw smoke coming from the bus’ engine. “It was jaw-dropping,” he told reporters.By the time Alex and some other kids made it out the bus’ back door, the bus was already on fire. And some of their schoolmates were still inside. So he and some of the other older kids took action.“One little kid was slowing everyone down with his big backpack, ” eighth grader Destiny Fain said, “so I got it off and threw it to the side and helped to make sure all the little kids weren’t fighting or pushing. ”As that was going on, sixth grader Marketez Doyle-Smith reportedly helped another classmate who had trouble in breathing because of the smoke. “We saw our friend lying on the ground,” he said, “so we took our shirts off and waved them to get him some air to breathe.”Marketez also reportedly stopped a younger kid trying to get back on the bus to search for something he’d left behind. “We're all a family,” he told reporters. “So I went back to help the little kid.”Finally everyone made it off safely, thanks to Alex, Destiny, Marketez and several other kids. By later that day, they were already being called heroes. “I really don’t see it as being a hero,” Alex said, according to The World. “I see it as the right thing to do—helping others before you help yourself.”1. What happened on Alex’ s way home?A. The school bus was on fire suddenly.B. There was a party for Alex’s birthday.C. He received a gift from his classmate.D. Some classmates quarreled with each other.2. By saying "We're all a family.” Marketez probably meantA. We’re brothers in the same family.B. It’s our duty to help each other.C. We’re classmates in the same class.D. The thing left on the bus is mine.3. According to the last paragraph, Alex thought that heA. was not a brave student.B. had the right to do anything.C. had just done what he should do.D. hated to be called a hero by others.BKamikatsu, a small town in Japan, has shown the world that our garbage has far-reaching effects, and not just on our environment.Theexperiment in going zero waste started when the town built a new incinerator 20 years ago. But almost immediately, the incinerator was determined to be a health risk due to the poisonous gases when garbage was burned in it. It was too expensive to send waste to other towns, so locals had to come up with a new plan. Then the Zero Waste Academy was born, which helped perform this plan.Now Kamikatsu people separate their waste into 45 different categories. But in the beginning, it wasn't easy to convince local people to do all this work, and there was somepushback. Only after that initial education period did most residents come on board.This is all great news for waste reduction of course, but it has also had some unexpected social benefits as well. Like much of Japan, Kamikatsu's population is aging, and about 50 percent of the locals are elderly. The fact that the whole community takes their trash in to be recycled has created a local action and interaction between generations.That idea has been purposefully expanded to include a circular shop where household goods are dropped off and others can take them, and a tableware "library" where people can borrow extra cups, glasses, silverware and plates for celebrations."The elderly see this not as a waste-collection service, but an opportunity to socialize with the younger generation and to chat. When we visit them, they prepare lots of food and we stay with them for a while, we ask how they are," Sakano, the founder of the Zero Waste Academy, said.Sakano's ideas are truly revolutionary if you think about it. She's proving that community can be found through handling the stuff we no longer want and need.4. What is mainly talked about in paragraph 2?A. What harmful effects garbage burning has.B. Why garbage sorting is necessary in Japan.C. How the idea of zero waste was put forward.D. What the Zero Waste Academy functions as.5. What does the underlined word "pushback" probably mean?A. Inactive response.B. Generous reward.C. Bitter suffering.D. Beneficial guidance.6. What is a bonus of the zero waste project?A. Reducing waste.B. Creating community.C. Increasing people's income.D. Developing a new technology.7. Which part of a newspaper is this text most likely from?A. Technology.B. Health.C. Workplace.D. Lifestyle.CImagine that youare a superhero. Your superpowers are activated by a special suit. The suit communicates with your brain. It allows you to do amazing things with only a thought. By concentrating on strength, for example, you can kick a soccer ball across a field. By focusing on swift actions, you can jump to the top of a tree.Such a connection between mind and machine may sound like a fantasy. To scientists, though, it is a very real goal. They are creating machines that let disabled monkeys walk. These machines may soon help disabled humans do the same. Unlike other bionic devices, these robotic “super suits” do not communicate with muscles and nerves. Instead, they have a direct line to the brain.In 2005, doctors drilled a hole in the skull of Hutchinson, who had lost her right arm in an accident. Then they inserted a sensor onto her motor cortex (大脑皮层运动区). Wires connected the sensor to a receiver on her head. After she recovered, researchers pluggedHutchinson’s receiver into a cable that relayed signals from her brain to computers. Then they connected a robotic arm to the computers. The computerscould interpretHutchinson’s brain signals to move the arm.Soon,Hutchinson, the computer, and the robotic arm became a team.Hutchinsonwas even able to lift her hand and drink from a cup. “She smiled when she put down that drink—that’s everything.” says Donoghue, a brain scientist.Today other scientists are building on that success. One of those scientists is Dr. Miguel Nicolelis, who designed a whole-body bionic equipment. In 2014, a disabled former athlete kicked the first ball of the World Cup Games wearing one of Miguel’s full-body exoskeletons.The exoskeleton was connected to brain signal sensors in the man’s cap. By thinking about kicking, he sent signals to a computer on his back. The computer then translated the signal into an exoskeleton-aided kick. Such designs may become common as scientists keep merging mind and machine.8.Which can best describe the tone of paragraph 1?A. Narrative and serious.B. Persuasive and critical.C. Informative and objective.D. Descriptive and imaginative.9. What is paragraph 3 mainly about?A. Reason of the experiment.B. Results of the experiment.C. Process of the experiment.D. Significance of the experiment.10. Why is Dr. Miguel’s exoskeleton special?A. It can be used on animals.B. It can move the whole body.C. It was supported by computers.D. It was connected directly to the brain.11. What can be inferred from the last paragraph?A. Robotic suits may be widely used to help disabled people.B. Exoskeleton is more common thanHutchinson’s bionic arm.C.Scientific experiments are commonly carried out in football fields.D. Disabled athletes can now play football again with the help of computer.DWhen Jennifer Doudna was in sixth grade, she came home one day to find that her dad had lefta book titled The Double Helix on her bed. She put it aside, thinking it was one of those detective tales she loved.On a rainy Saturday, she picked up the book. As she sped through the pages, she became fascinated by the drama, which encouraged her to explore nature's wonders. Even though her high school teacher told her that girls didn't become scientists, she decided she would.She worked with a biologist, Charpentier, to turn a curiosity of nature into an invention—an easy-to-use tool that can edit DNA. Known as Crispr, the tool will transform the human race. James Watson, the author of The Double Helix, later told her it was the most important biological advance: since he and Francis Crick discovered the structure of DNA.For this achievement, Doudna and Charpentier were awarded the Nobel Prize in Chemistry in 2020. Until now, only five women, beginning with Marie Curie in 1911, had won or shared the Nobel for Chemistry out of 184 award winners. When this year's prize was announced, Dr. Charpentier said it would provide a message specificallyto young girls who would like to follow the path of science and to show them that women can also be awarded prizes.A few decades from now, if it becomes possible and sate to edit DNA, should we allow parents to improve the IQ and physical strength of their kids? Should we let them decide eye color1 ? Skin color1 ? Height? After helping to discover Crispr, Dr. Doudna has become a leader in considering these moral issues.

1)The cylinder block is the foundation of the engine—all other parts are attached to
it.
2)Two kinds of cylinder liners, dry liner and wet liner, can be installed after the
cylinder block is cast.
3)The cylinder heads on many engines also form the upper end of the combustion
chambers for each cylinder. The piston head and piston rings form the lower end of the combustion chambers.
4)Attached to the cylinder head are such components as valve mechanisms, spark
plugs or injectors, exhaust and inlet manifolds, temperature sensors, heater hose connectors, top radiator hose connector, and a rocker or camshaft cover.

1)The piston must be strong. But it must be light to reduce inertia loads on the
bearings. For this reason, pistons for modern engines are made of aluminum alloy.
This is a light metal.
2)The piston rings maintain a sliding seal between the cylinder wall and the piston.
3)During manufacture, the rods and caps are individually matched to each other.
They usually carry identifying numbers so that they will not be mixed up if the engine is disassembled.
4)The crankshaft assembly includes the crankshaft, bearings, flywheel, harmonic
balancer, timing gear, and front and rear seals.
