辽宁省重点高中协作校联考2024届高三下学期4月高考模拟考试英语试题

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。

Deep below the ground, radioactive elements break up water molecules(分子), producing substances that can fuel subsurface life. This process, known as radiolysis(辐射分解),has supported bacteria in tiny cracks filled with water on Earth for millions to billions of years. Now a study published in Astrobiology shows that radiolysis may have supported life in the Martian subsurface. 

Dust storms, rays in the universe and solar winds ruin the Red Planet's surface. But below, some life might find shelter. "The best survival habitat on Mars is the subsurface," said Jesse Tarnas, a planetary scientist at NASA, Examining the Martian underground could help scientists learn whether life existed there. And the best subsurface samples available today are Martian meteorites(陨石) that have crash-landed on Earth.

Tarnas and his colleague looked at the minerals on the Martian surface and how many radioactive elements there were, using satellite and rover data, They used computers to simulate(模拟) radiolysis to see how efficiently the process would have generated life-supporting hydrogen gas and other chemical substances. They reported that if water was present, radiolysis could have supported life for billions of years and perhaps still could today. 

Scientists had previously studied Mars radiolysis, but this marked the first estimate using Martian rocks to see how habitable Mars underground might be. Tarnas and his colleagues also evaluated the potential richness of life in Martian underground.They found that up to a million bacteria could exist.in just one kilogram of rock, The most habitable seemed to be the southern highlands of Mars, which is the most ancient area on Mars, according to Tarnas.

"Underground life would require water and it remains unknown if groundwater exists on the planet," says Lujendra Ojha, a planetary scientist at Rutgers University. Determining whether the Martian, subsurface contains water. will be an important next step, but this investigation helps to motivate that search, Ojha says, "Where there is groundwater, there could be life."

(1)、What does radiolysis refer to according to the passage?!
A、The formation of water deep underground. B、The breakdown of rocks in the Earth's core. C、The production of energy from radioactive elements. D、The process of radioactive elements splitting water molecule
(2)、 How did Tarnas and his colleague carry out their research? 
A、By simulating with collected data. B、By comparing original data. C、By engaging in a Martian field research. D、By conducting a survey.
(3)、Which can be inferred from the last 2 paragraphs?
A、Tarnas is the first to study Mars radiolysis B、The presence of groundwater is key to the findings. C、Ojha questions that underground life exists on Mars. D、The southern highlands of Mars was home to millions of bacteria.
(4)、What is the research mainly about?
A、The reason for no life on the Martian surface. B、The data source for the study of Martian habitability. C、The possibility of Mars sustaining life through radiolysis. D、The richness of radioactive elements below the Martian surface.

阅读下列短文,从每题所给的四个选项 (A 、B 、C  和 D )中,选出择最佳选项。

    Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening.

    One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent (租住). With the same money, one can get a little house in the country with a garden of one's own.

    Then, in the country one can rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one's free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has the reward of sharing the secret of Nature.

    Some people, however, take no interest in country things:for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight's (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night.

    Fighting racial stereotypes(模式化)on US campuses often begins by putting students of different ethnic backgrounds together — under one dormitory roof.

    Sam Boakye was a freshman at Ohio State University and the only black student on his floor. He was determined to get good grades — in part to make sure his white roommate had no basis for negative racial views. "You're pushed to do better, to challenge the stereotype that black people are not that smart," he told the New York Times.

    Several recent studies have found that having a roommate of a different race can reduce prejudice(偏见), diversify(使多样化) friendships and even promote students' academic performance. In a study by Ohio State psychology professor Russell Fazio, black freshmen who came to college with high test scores earned better grades if they had a white roommate—even if the roommate's test scores were low. Another study on student interaction by Duke University suggests that freshmen with roommates of a different race were the most likely to diversif“y their friendships. Just having diversity in classrooms doesn't do anything to increase interracial friendships," said Claudia Buchman, an author of the Duke study. “But living together with a different-race roommate does lead to more interracial friendships."

    There are, however, some problems with such room assignments. Fazio's study found that three times as many randomly(随机地) assigned interracial roommates weren't living together at the end of the semester, compared with white roommates. Interracial roommates also spent less time together, had fewer joint activities and were less involved with each other's friends than white pairs.

    As for Boakye, this is not the case. "A lot of white students come without much exposure(暴露)to diversity, so when their first interaction with a black guy isn't bad, they will make more black friends. I think I made a good impression on my freshman roommate. I saw him this year, and he said, "Hey dude, you're not the only black friend I have. That felt good."

    I was a bit of a bookworm as a child.For car journey,day trip or family holiday,many books were always packed to keep me busy.Since then,I've continued reading all kinds of books but I'll always love my childhood favorites.

    The Curious Incident of the Dog in the Night-timer—Mark Haddon

    This children's mystery novel is interesting,exciting,thought-provoking(发人深省的),sad and happy all at the same time.The main character is a 15-year-old boy who has autism(自闭症). The book gives you a window into his world, his thoughts, his hopes and his dreams. It's easy to read and both kids and adults love it.A must-read in my opinion.

    Secret Seven—Enid Blyton

    If you love adventures,this one is for you.The Secret Seven are a group of child detectives who make it their duty to solve crimes.They have many adventures along the way.It's a fun book that you won't want to stop reading. And in fact, there is more than.one book.There's a series of books about the Secret Seven's adventures so if you like the first one, you're in luck.

    Matilda—Roald Dahl

    It's now a film and show at the theatre,but we can't forget the original book.Matilda is about a loveable little girl who is very clever and,like me,loves to read.She goes to school and meets the very scary Miss Trunchbull who tortures(折磨)children,but thankfully makes friends with a kind teacher. The book will have you crying one, moment and laughing the next.

    The Lion, the Witch and the Wardrobe—C.S.Lewis

    As a kid I read the book, watched the film and listened to the tape.I really couldn't get enough of the book.It's an exciting story set in a magical land called Narnia. When you're reading it, you'll feel like you're really there.You'll get caught up in the adventures of the four children and the characters they meet.I can't rate it highly enough.

    You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created lampbrella, a lamp post with its own rain sensing umbrella.

    The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp.” he said.

    The lampbrella is a standard-looking street lamp fitted with an umbrella canopy with a built-in electric motor which can open or close the umbrella on demand. Sensors(传感器)first ensure that it starts raining and the motors open up in response to their sensors and then people can protect themselves from the rain under the canopies.

    In addition to the rain sensor, there's also a 360° motion sensor on the fiberglass street lamp which detects whether anyone's using the lampbrella. After three minutes of not being used, the canopy is closed.

    According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each lampbrella would offer enough shelter for several people. Being installed(安装)at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.

    While there are no plans to take lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

    Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the "on/off" button on the TV. But some buttons are actually fake, like the "close" button on a lift.

    Many people are in the habit of pressing the "close" button because they don't have the patience to wait for the lift doors to shut. But lifts' "close" buttons are a complete scam (骗局), at least in the US-the doors will not close any faster no matter how hard you press.

    It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

    But to normal lift riders, the buttons aren't completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control.

    "Perceived (能够感知的) control is very important. It reduces stress and increases well-being," Ellen J. Langer, a psychology professor, said, "having a lack of control is associated with depression(沮丧)."

    Experts have revealed that a lot of buttons that don't do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workplace.

    Pedestrian(行人) crosswalk buttons don't live up to their names either. Pressing them used to help make the traffic signals change faster, but that was before computer-controlled traffic signals were introduced.

    But psychologists found it interesting that even when people are aware of these little "white lies", they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

    "That habit is here to stay," John Kounios, a psychology professor, said. "Even though I have real doubts about the traffic light buttons, I always press them. After all, I've got nothing else to do while waiting. So why not press the button in the hope that this one will work?"
