2020-2021学年天津市实验中学高三英语月考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AAs a nation, we are getting bigger and eating more. But there are effective ways to control your appetite and eat only as much as you need.Keep away from low-nutrition snacksThat means ice cream, sweets, chips biscuits, cakes and any other salty orsugary snacks you eat between meals. Although we have a tendency to eat them, you can learn to live without these unhealthy-and-fattening-additions to your diet. Try to make it a habit to eat them only when offered at social events or as a special treat.Leave half an hour between main course and dessertHaving a break between courses gives your brain time to receive the fullness signal and make you more likely to refuse the sweet stuff. And, in fact, as soon as you feel the first signals of fullness, remove your plate from the table. That will tell your brain that food time is over.Make yours a small helpingPut an end to super-sized portions. You won’t be missing out—today’s small was the medium or large of a few decade ago. Select or serve yourself a modest portion and eat it slowly enjoying the flavors. Before you know it, small will feel just right. What’s more, ordering the smaller size leads to wearing the smaller size.Distract yourselfWhen you find yourself hunting down food, even though you’re even hungry, do something else for 20 minutes. Drink a large glass of water as thirst is often confused with a desire for food. Choose something that engages your brain as well as your hands, such as writing a letter or listening to a song. You could also go for a short walk or do something that you enjoy. If you think you really are hungry, set an alarm for 20 minutes’ time and if you still want to eat when it rings, fine. If not, the urge will have passed.1. Which way suits you better if you tend to order a large portion of food?A. Distract yourself.B. Make yours a small helping.C. Keep away from low-nutrition snacks.D. Leave half an hour between main course and dessert.2. Why should you have a break between main course and dessert?A. To give people time to chat.B. To have a good appetite for sweet stuff.C. To reduce appetite for dessert.D. To give the host time to remove your plate.3. When you find yourself pursuing for food, what should you do?A. Eat some biscuits.B. Eat some sugary snacks.C. Have some soft drinks.D. Listen to a lovely melody.BMost people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world’s population is left-handed.Why are there more right-handed people than left-handed ones? Scientists now know that a person’s two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person’s hands and eyes work together, controls the left hand. The left-side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn’t happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene(基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don’t have to.4. After studying works of art made at different times in history, the scientists found _______.A. the art began from 1,500B.C.B. the works of art ended in the 1950sC. most people shown in the works of art are right-handedD. most people shown in the works of art are left-handed5. What is the left hand for most people used to do?A. It’s used to find or hold things.B. It’s used to work with things.C. It’s used to make a person’s eyes work together.D. It’s the centre for thinking and doing problems.6. According to the passage, which of the following is NOT true?A. No one really knows what makes a person become right-handed.B. Left-handedness is cleverer than right-handedness.C. Today children are not made to use their right hands only.D. Scientists think there must be some reason why people become left-handed.7. The best title for this passage is _______.A. Scientists’ New InventionsB. Left-handed PeopleC. Which HandD. Different Brains, Different HandsCTo hear people talk about Internet friendships, you would think it was one giant web of cat-fishing and e-crime. While we all undoubtedly have to take measures to remain safe online, assuming every friendship or connection made on Instagram, Twitter or Facebook is cheating or insincere would be a mistake.As a woman who works in the creative industry, I have found real joy in seeking out a community I couldn’t find elsewhere, and making some great friends along the way. My first online friendship was on Twitter with my(now) best friend, during the university exam period. We exchanged study notes in dozens of direct messages, set a study date, and haven’t looked back since.Drawn to each other by similar circumstances, friendships online are similar to offline in that they tend to begin because of shared interest or common ground-maybe they’ve read the post on Instagram. Maybe they have the same taste in food or politics. Or maybe they just love memes too. If online friendships start similar to friendships offline, they grow in the same way, too. Often through mutual support: apart from calling a friend tocongratulate him on that new job, you also re-tweet his jokes and praise his Instagram story.Despite my positive experiences when I tell people, most are still suspicious. Eyebrows are raised higher when I explain not only have I found a community online but have made friendships with people I meet face-to-face too. Actually, these are just as valid as other friendships, according to behavioural psychologist Jo Hemmings, who says online friendships can be real.So how do you know if people are there for the real you or just because you’re popular on Instagram? Hemmings has simple rules. She tells me “You have to equally feel comfortable that you’re getting something of each other instead of being used to enable something that isn’t friendship.”Therefore, if all a “friend” online is asking you to do is to promote their work or personal brand and rarely takes an interest in you, then there may be room to question the basis of the friendship. On that note it is worth remembering that just because someone has a lot of followers, it doesn’t necessarily mean they have lots of friends.8. What is most people’s attitude towards online friendship?A. Negative.B. Positive.C. Objective.D. Neutral.9. Why does the writer share her own experience in paragraph 2?A. To introduce the background information of the text.B. To convey the writer’s attitude and give the related example.C. To prove the likely risk for people to develop friendship online.D. To remind people of the various benefits of making friends online.10. How can online and offline friendships be deepened?A. They should be based on shared interest.B. They need to have common ground.C. They require support from each other.D. They can’t live without social media.11. According to the author, what’s the golden rule to make friends online?A. A friend to all is a friend to none.B. Without confidence there is no friendship.C. A friend without faults will never be found.D. Friendship cannot stand always on one side.DPablo Picasso was born on October25 inMalaga. Spain in 1881. Taking after his father, Picasso shared apassion（热爱）for painting and art. Even though he wasn't the best student in school, Picasso excelled at drawing. Noticing his amazing talent, Picasso's father, an artist, taught him everything he knew. Before long, Picasso could paint and draw much better than his father. With this rich talent, Picasso paid less and less attention to his schoolwork and spent the majority of his day sketching and drawing in notepads and sketchbooks.When he was a little bit older, Picasso moved twice and was accepted into two fine art programs. However, he didn't care very much for the special techniques they taught and often wandered the streets by himself drawing the scenes around him. After moving to these two places, Picasso moved back home toBarcelonaand decided that he would develop new techniques of art and painting based on what he saw.Later, Picasso decided to move toParis,France, where he began perfecting his own techniques of painting, drawing and other forms of art. His drawings. paintings, and an included pieces about sadness, poverty, classics and self-portraits. One of his major types of work is calledcubism（立体派），which includes art with all sizes of geometric shapes together on the piece of an. This type of art is very important because no other artists had come up with the idea before. Picasso decided to try something new, and as a result, cubismis widely accepted today as a classic style of art.Picasso inspires us to always be thinking. He tells us to think outside the box and come up with fresh new ideas that can change the world. He surely plays a significant role in the art field.12. What do we know about Picasso as a student at school?A. He hated doing his homework.B. He was very proud of his talent.C. He showed great talent for drawing.D. He was often praised by his teacher.13. What did Picasso's father do when he found Picasso's gift?A. He tried his best to help Picasso.B. He blamed Picasso for his laziness.C. He asked Picasso to finish his work on time.D. He encouraged Picasso to do better at school.14. What was Picasso's attitude towards the special techniques at that time?A. He thought highly of them.B. He took no interest in them.C. He was confused about them.D. He was concerned about them.15. What does the author tell us in the last two paragraphs?A. Picasso has great faith in art.B. Picasso has changed the world a lot.C. Picasso can do anything he wants to.D. Picasso is a highly creative artist.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

In the past, we just had the Internet while now we have the Internet of Things (IoT), which aims to get everything and everyone talking. Attaching sensors to “things”, such as cows, cars and refrigerators, and then assigning them unique IP addresses allow them to “talk” to the Internet. Of course, the IoT will involve much more than a handful of sensors. Networking company Cisco estimates that 50 billion Internet-connected devices and objects will be sending over data by 2020.36．How do researchers get everything and everyone talking?A．By establishing the IoT and launching a handful of sensors.B．By sending people to track them day and night and collect useful data.C．By communicating with them all the time through the IoT.D．By connecting sensors with them and appointing them unique IP addresses. 37．According to the passage, which of the following is NOT TRUE?A．IoT can help people do preventive maintenance and save money.B．IoT can help people monitor energy usage and observe price changes timely.C．IoT can help people adjust their habits and use electrical appliances more wisely.D．IoT can help people investigate things and update a lot of important data. 38．Besides its probably ending up being a fashion, what else do critics worry about the IoT?A．People will lose interest in it as quckly as the thrill over last year’s smartphone.B．Whether related companies will provide long-term software updates or not.C．Refrigerators and washing machines will be replaced by other devices in a few years.D．The software provided by companies will be outdated easily and quickly. 39．According to the passage, when owners of the Tesla Model S electric car received a recall notice, they ___.A．just waited in the car while the maintenance is being done through wireless update B．were required to go to the nearest 4S store to make some adjustments or repairsC．could definitely depend on the IoT to send them the charger plug to be fixedD．had to confirm the update with the help of the equipment provided by the company 40．What would be the best title for the passage?A．Craze is disappearing!B．It’s time to change!C．It’s all connected!D．The Internet is coming!It was a cold May morning when I received an intriguing (有趣的) email from an old high school friend inviting me to join a 10-day all-girls surf trip. I knew I had to say yes.The trip seemed simple enough. Ten women aged 30 to 45, all complete strangers, gathered on the coast of Portugal to try something new: surfing in the Atlantic Ocean.I have always loved traveling, so I eagerly sent an email to my boss seeking permission from him to make the once-in-a-life trip.If there’s one thing I’ve learned over my past 33 years, it’s that adults typically spend their days mastering the things they’ve done before. It seems like we pride ourselves on becoming experts in whatever field we’ve fallen into, knowing more and more about less and less.Now, in theory, this is a great strategy, as it allows you to become really, really good at one particular thing, but it also kind of ends up leaving some skills lacking.I met my new surfing companions on the grass of the hotel lawn in a small surf town called Ericeira. Despite our different personalities and backgrounds, we were all united in a relentless desire to challenge ourselves, learn, tackle and grow.The shores at Ericeira, where the beginners learn to surf, are shallow and covered with slippery rocks. They make for softer waves but are difficult to navigate.Guided by our amazing coaches, together, we faced the waves. Sometimes, it poured with rain, and the waves crashed around us, but we were still out there. And with every slip and fall, words of encouragement filled the air.Honestly, I probably spent most of my days frozen to the bone, but that didn’t matter because a new level of genuine joy and personal achievement had been unlocked. Learning a new skill taught me the humility that can come from doing badly at something new, and the pride that develops when you finally manage to grasp something you’ve been working on.While surfing might not be my calling, trying it out inspired me to take more risks in life, to step outside of my comfort zone and to never stop believing in myself. You never know what you’re capable of if you don’t go out there and try.41．What motivated the author to join the surf trip to Portugal?A．Her love for surfing and improving existing skills.B．Her desire to reconnect with a high school friend and make new friends.C．Her passion for embracing challenges and exploring new places.D．The chance to take a break in Portugal from work.42．What is the author’s view on adults focusing on mastering one field?A．It blocks creativity and exploration.B．It is essential for career success.C．It disturbs one’s work-life balance.D．It narrows one’s abilities.43．Which of the following words best describe the author’s surfing experience?A．Tough but rewarding.B．Relaxing but unpredictable.C．Difficult but interesting.D．Tiring but meaningful.44．What can be inferred about the author?A．She discovered her true calling atter the trip.B．She used to lack confidence in herself.C．She became more willing to challenge herself.D．She went on to become an expert surfer.45．What wisdom did the author gain from the experience with surfing?A．The need to seek professional training in all new skills.B．The value of pushing your limits and running the risk of something unpleasant.C．The benefit of exploring new places with unknown companions.D．The importance of being an expert in on field.The Internet has completely changed the workplace over the past three decades. Artificial Intelligence is now all set to do the same, and businesses that don’t take advantage of the technology risk being left behind.Global tech giants like Amazon have been leading the change, and businesses of all sizes are now using the technology for employing and managing their staff.Among them is L’Oreal. With about a million applicants for roughly 15,000 new positions each year, the company is using AI to hire.“We really wanted to save time and focus more on quality, diversity and candidate experience. And AI solutions were the best way to go faster on these challenges,” said Eva Azoulay, global vice-president of L’Oreal’s Human Resources Department.The company uses Mya, a chatbot, to save employers’ time during the first stage of the process. It handles routine questions from candidates, and checks details such as availability and visa requirements. Should candidates make it to the next round, they’ll run into Seedlink, an AI software that scores applicants based on their answers to open-ended interview questions. These scores don’t replace human judgment, said Azoulay, but they do exclude candidates who might not seem like obvious choices.Early results have been promising. For one internship program, where 12,000 people apply for about 80 spots, employers claim they saved 200 hours of time while hiring the most diverse group to date.Other businesses have gone beyond employment and are using AI to help manage employees. Some UK firms have started using Isaak, a system designed by the London-based company StatusToday, to track how many hours staff spend online and the number of emails they receive. London real estate agent JBrown has been using this system since March. CEO James Brown said it helps the firm understand employees’ habits and prevent them from overworking. “It enables us to solve bottleneck problems and relieve overburdened employees,” he said.Despite these examples of good practice, there is still a long way for AI to reach its full potential, and the technology comes with risks. Another AI danger could be its impact on jobs through automation.McKinsey predicts AI could add $13 trillion to the global economy by 2030, with early adopters doubling their cash flow over that period. But the demand for repetitive (重复的) or digitally-unskilled jobs could drop by around 10%, the consulting firm said in a 2018 report. 46．What can we learn about AI technology from Paragraph 1?A．It causes a great problem in workplace.B．It will become a necessary part of business.C．It requires businesses to invest much money.D．It will replace the Internet in the future.47．L’Oreal uses AI in its hiring process to _____.A．pick out the most suitable candidates directlyB．come up with more questions unlimitedlyC．improve the company’s hiring efficiencyD．save money by replacing human judgment48．What’s the meaning of the underlined word “exclude” in the 5th paragraph?A．Prepare.B．Consider.C．Remove.D．Include. 49．Firms with the system Isaak can _____.A．prevent their employees from surfing the InternetB．force their employees to form good working habitsC．monitor the contents of all their employees’ emailsD．help their employees avoid being overstressed at work50．What is the main idea of the passage?A．What AI will bring to the workplace.B．Why AI could be good for the workplace.C．How businesses can prepare for an AI future.D．How to use AI to improve workplace efficiency.Culture can affect not just language and customs, but also how people experience the world on surprisingly basic levels.Researchers, with the help of brain scans, have uncovered shocking differences in perception (感知) between Westerners and Asians, what they see when they look at a city street, for example, or even how they perceive a simple line in a square, according to findings published in a leading science journal.In western countries, culture makes people think of themselves as highly independent individuals. When looking at scenes, Westerners tend to focus more on central objects than on their surroundings. East Asian cultures, however, emphasize inter-dependence. When Easterners look at a scene, they tend to focus on surroundings as well as the object.Using an experiment involving two tasks, Dr Hedden asked subjects to look at a line simply to estimate its length, a task that is played to American strengths. In another, they estimated the line’s length relative to the size of a square, an easier task for the Asians. The level of brain activity, by tracking blood flow, was then measured by Brain Scanners. The experiment found that although there was no difference in performance, and the tasks were very easy, the levels of activity in the subjects’ brains were different. For the Americans, areas linked to attention lit up more, when they worked on the task they tended to find more difficult — estimating the line’s length relative to the square. For the Asians, the attention areas lit up more during the harder task also — estimating the line’s length without comparing it to the square. The findings are a reflection of more than ten years of previous experimental research into east-west differences.In one study, for instance, researchers offered people a choice among five pens; four red and one green. Easterners were more likely to choose a red pen while Westerners were more likely’ to choose the green one.Culture is not affecting how you see the world, but how you choose to understand and internalize it. But such habits can be changed. Some psychological studies suggest that when an Easterner goes to the West or vice versa, habits of thought and perception also begin to change. Such research gives us clues on how our brain works and is hopeful for us to developprograms to improve our memory, memory techniques and enhance and accelerate our learning skills.51．According to the passage, Chinese people are most likely to ___.A．more emphasize independent thinkingB．always focus more on their surroundingsC．think of Westerners as highly independent individualsD．focus more on the context as well as the object52．We know from the passage that people’s brains will be more active when ___.A．the task is much easier B．the blood flow is trackedC．the task is more difficult D．people begin to choose colors 53．What do the findings of the experiment mentioned in the 4th paragraph indicate?A．They indicate that culture has a great impact on the way people talk and behave.B．They show that Easterners and Westerners have great differences in perceiving the world.C．They suggest that people’s habits of thought and-perception can be changed indifferent cultures.D．They make it clear that Easterners and Westerners lay emphasis on different things. 54．It can be inferred from the passage that ____.A．Easterners prefer collectivism to individualismB．East Asian cultures lay more emphasis on independenceC．It took over ten years to find out how to improve our brainpowerD．Americans will change their habits of perception when they’re in Britain 55．Which of the following will be the best title of the passage?A．Chinese culture: why it has an advantage over Western culture?B．Western culture and Chinese culture: which will be more suitable for us?C．Western culture and Chinese culture: why we should learn from both?D．Western culture vs. Chinese culture阅读短文, 按照题目要求用英语回答问题。
