2020年中考英语阅读理解15篇冲刺训练（精选中考真题+解析答案，值得下载）（一）Scientists have learned a lot about the kinds of food people need.They say that there are several kinds of food that people should eat every day. They are: green and yellow vegetables of all kinds；&日业（柑橘）fruit and tomatoes；potatoes and other fruit and vegetables；meat of all kinds, fish and eggs；food made from milk；bread or cereal（谷类）,rice is also in this kind of food；butter or something like butter.People in different countries and different places of the world eat different kinds of things. Food is cooked and eaten in many different kinds of ways. People in different countries eat at different times of a day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn't matter whether food is eaten raw（生的）or cooked, canned（罐装的）or frozen. It doesn't matter if a person eats dinner at four o'clock in the afternoon or at eleven o'clock at night. The important thing is what you eat every day.There is a large number of people on the earth. There are two problems in feeding them. The first is to find some ways to make enough food so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food so they can grow to be strong and healthy.（）61. According to the scientists, which of the following groups of food is the healthiest for your lunch?A. Oranges, bananas, fish and tomatoes.B. Chicken, apples, cereal and cabbage.C. Beef, pork, fish and milk.D. Potatoes, carrots, rice and bread.（）62.It is important for people to eat.A .different kinds of food every day B. dinner at eleven o'clockC. cooked food all the timeD. three times a day（）63.People in different countries and different places of the world.A. have the right kinds of food to eatB. cook their food in the same wayC. eat food in different waysD. have their meals at the same time（）64.Which of the following is NOT true?A.People in some places don't have enough food to eat.B.There are too many people in the world.C.The scientists are trying to make people grow to be strong and healthy.D.One of the problems is that no one is hungry.()65.If there is paragraph 4,what do you think is going to be talked about?A. When people eat their lunch.B. How to cook food in different ways.C. What to do with the two problems.D. Why people eat different kinds of food.(二)Researchers have studied left-handedness for at least 150 years. However, what makes a person become left-handed remains unknown, although there are many theories about it.A recent UK study of unborn babies found that handedness might develop before their births. About nine out of ten unborn babies preferred to put their right hand into their mouths. Another finding is that mothers who are over 40 at the time of a child,s birth are 128% more likely(可能的)to have a left-handed baby than a woman in her twenties.Since about 90% people are right-handed, left-handed people do go through some difficulties. As our writing runs from left to right, it is hard for a left-handed person to write without smudging( 模糊)the ink. What,s more, most tools such as scissors and kitchen knives are designed for use with the right hand. It can be dangerous if they are operated with the left hand.In the past, left-handed children were forced to use their right hand. Luckily, now fewer people have a bias against left-handers. Left-handed children are no longer looked down upon in school. Some shops sell products for left-handers, such as left-handed guitars and even a left-handed computer mouse. Since 1976, there has been an unusual day for left-handers. International Left- Handers Day is celebrated on August 13th every year. It draws people,s attention to the challenges left-handers face in a world full of right-handers. More and more people have realized left-handedness is nothing strange. Some of the most famous left handed people include Mark Twain, Winston Churchill, Barack Obama and Bill Gates.()61. A baby may develop left-handedness when.A. nine out of ten babies do soB. his mum is in her twenties at his birthC. his mum gives birth to him at an older ageD. he puts his right hand into his mouth often()62. One problem for left-handed people is that.A. their handwriting is awfulB. people think they are dangerousC. kitchen knives are too big for their left handsD. many things are made only for right-handers( )63. The underlined word “bias” means in Chinese in this passage.A.态度B.偏见^恐惧 D.偏好( )64. From the passage, we know that left-handed children in the past.A. lived a comfortable lifeB. were not considered normalC. were very popular at schoolD. could use products for left-handers（）65. The best title of this passage is.A. International Left-Handers DayB. Challenges for Left-handersC. Left-handedness, Nothing StrangeD. Reasons for Left-handedness（三）Your house may have an effect on your shape of your body. Experts say the way you design（设计）your home could play a role in whether you put on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to change your home into part of your diet plan.Open the curtains（窗帘）and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less awkward when they,re in poorly lit places—and so more likely to eat lots of food. If your home doesn't have enough window light, get more lights and flood the place with brightness.Mind the colors. Research suggests warm colors make us eat more. In one study, people who ate meals in a blue room consumed（消化）33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizin g while cold colors make us feel less hungry. So when it's time to repaint, go blue.Don't fOrget the clock-or the radio. People who eat slowly seem to consume about 70 fewer calories（卡路里）per meal than those who rush through their meals. Begin paying attention to the time, and try to make dinner last at least 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake（摄取量）jumps by 14 percent. And we,ll pour about 30 percent more liquid液体）into a short, wide glass than a tall, skinny glass.（）61. The passage is especially helpful for those who care about.A. house buyingB. their body shapeC. healthy dietsD. their home comforts（）62. A home environment in blue can help people.A. take in food betterB. burn more caloriesC. reduce food intakenD. feel less awkward（）63. The underlined word “appetizing” probably means in the passage.A.精致的B.恶心的C.饱腹的D.开胃的（）64. People advised to at mealtimes.A. eat quicklyB. play fast music.C. use smaller spoonsD. turn down the lights（）65. The best title for the passage is.A. Ways of Serving DinnerB. Is Your House Making You Fat?.C. Effects of Self-awarenessD. Is Your Home Environment Relaxing?（四）Animals can move from place to place , but plants cannot. When an animal is under attack , it can run away or fight back. Plants certainly cannot run away , and they have no teeth or claws. But plants can protect themselves in both physical and chemical ways.Some plants have their own ways to keep animals away. For example , the leaves of the holly （冬青）have sharp prickles （刺）that discourage grass eating animals. Holly leaves on lower places have more prickles than leaves on upper places. Thisis because the lower leaves are easier for most animals to reach. Some plants , such as the oak 口匕匕$（橡树），have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material , and eating such grasses wears down the animals, teeth. Many plants also have chemical defenses. Some plants produce chemicals that taste bitter （苦）or cause anunpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a worm bites a tobacco leaf （烟叶）， the leaf produces a chemical smell. Many plants depend on both physical and chemical defenses. A certain plant in China , for instance , has prickly leaves , and each prickle has poisonous water （毒液）. Only one experience with this kind of plant will teach an animal to stay away from it in the future.（ ）61.A plant when it is under attack.A.can protect itselfB.can run awayC.can fight back （ ）62.According to the passage, the leaves of the holly have sharp prickles becauseA.they are beautiful to watchB.they stop people from picking（ ）63.An oak tree protects itself becauseA.it has leaves with sharp pricklesB.it has leaves with a sandy material （ ）64.What does the underlined word “sandy ” mean in Chinese?（五）A caterpillar （毛毛虫）that eats plastic bags could hold the key to solving plastic pollution , scientists say.Researchers at Cambridge University have discovered that the caterpillar which eats beeswax （蜂蜡）， can also degrade （降解）plastic.Experiments show the insect can break down the chemical bonds （键）of plastic in a similar way to absorbingD.must dieC.they stop grass-eating animalsD.they are lower C.it has thick and hard leaves D.its leaves taste bitterA.含盐的B.坏掉的C.含沙的 （ ）65.The main idea of this passage is.A.holly has its own ways to keep animals awayB.some plants, leaves can protect themD.腐烂的C.several ways to protect plantsD.plants can protect themselves in their own waysbeeswax.Each year , about 80 million tons of the plastic are produced around the world.The plastic is used to make shopping bags , food packaging , one-off raincoat and other things , but it can take hundreds of years to degrade completely.However , caterpillars can make holes in a plastic bag in un der an hour.“The caterpillar will be the starting point.We need to understand the details under which this process operates.We hope to provide the technical solution to cutting down the problem of plastic waste,” the scientist said. And the scientists who discovered it want to speed up the process of discovering the chemical secrets behind the natural degradation of plastic.They think something in the caterpillar 一as well as the insect itself -might play a role in breaking down plastic.If the chemical process can be found out , it could lead to a solution to managing plastic waste in the environment.“We are planning to use this finding in a practical way to get rid of plastic waste , working towards a solution to saving our oceans and rivers,” said the scientist.“However , we should not feel good to dump plastic on purpose in our environment just because we now know how to degrade it.”( )61.Scientists think the caterpillar hold the key to solving plastic pollution becauseB.it can be done experimentsC.it can degrade plasticD.it makes no waste( )62.Plastic is used for.A.making shopping bagsB.food packaging( )63.The key point of the solution is that.A.the caterpillar is a key point of the researchB.the chemical process which degrades the plasticC.the caterpillar plays a key role in breaking down plasticD.how to speed up the discovering of the chemical secrets ( )64.The underlined word “dump ” means in Chinese.A.购买B.售卖C.扔掉D.降解( )65.What is the best title of this passage?C.Scientists have found the chemical process （六）What is the worst disease in the world? Many people might say it is cancer (癌症).Cancer will kill about 9.6 million people in the world this year, according to the World Health Organization. Scientists have been working to find ways to beat cancer. A lot of progress has been made in this field.James P Allison from the US and Japanese researcher Tasuku Honjo discovered a new kind of cancer treatment that earned them the 2018 Nobel Prize in Physiology or Medicine in October. The new treatment can make our immune systems （免疫系统）strong enough to effectively fight cancer cells. It is hoped that this treatment can be used to treat most cancers in the future.This is not the only recent improvement in cancer treatment. In November, the US Food and Drug Administration approved a new cancer drug called Vitrakvi. Instead of being effective only for treating specific types of cancer, this drug can be used to treat 17 different kinds of cancer, including lung cancer and breast cancer, USA Today reported.A.it is fed on beeswax C.one-off raincoats D.all of the aboveA.How caterpillars degrade plasticB.Scientists are working towards plastic degrade D.Caterpillars may help to solve plastic pollutionFinding cancer as early as possible is the best way to beat it. To check people for cancer, doctors must collect tissue from a patient,s tumor （肿瘤）and test it. This process can take a long time. But in December, scientists from the University of Queensland in Australia developed a simple cancer test that can detect （检测）cancer in a patient,s blood. The test takes less than 10 minutes. The test is about 90 percent accurate, the Guardian reported.With all of these treatments, cancer can be effectively controlled. Honjo believes most kinds of cancer will become treatable by 2050. “Even if we cannot completely eliminate （消除）the tumor, we can survive while still having part of a tumor,“ Honjo said at a press conference in Stockholm, Sweden, in December.（）61.Who won the 2018 Nobel Prize in Physiology or Medicine?A. James P AllisonB. Tasuku HonjoC. VitrakviD. James P Allison and Tasuku Honjo（）62. Which of the following is TRUE about the new cancer treatment?A.It was discovered in October, 2018.B.It can be used to treat all the cancers in the future.C.It is the only recent improvement in cancer treatment.D.It can make our immune systems strong enough to effectively fight cancer cells.（）63. What does the underlined word “accurate” probably mean in Chinese?A.有风险的B）隹确的 C.错误的 D.有误差的（）64.According to the passage, the best way to beat cancer is to.A.find it as early as possibleB. eliminate the tumor completelyC. detect it in the patient,s bloodD. discover a n ew treatment（）65.The passage is mainly about.A. the great progress made to beat cancerB. a new cancer treatmentC. the best way to beat cancerD. two famous scientists（七）For us humans, one of the greatest experiences is to taste all kinds of delicious food.But for penguins, they cannot get a taste of this happiness. That,s because penguins can,t actually taste the delicious flavors （味道）of their favorite food-fish!Scientists from the University of Michigan examined the genome （基因组）of five species of penguins.They found that no one can taste umami （鲜味）,the flavor of meat or fish,the BBC reported.Many animals have five basic tastes: sweet, sour, salty, bitter and umami. But according to genetic data, penguins are believed tohave only sour and salty tastes.These findings are surprising and puzzling. And scientists don,t have a good explanation for them. But they have a few ideas.Fir st, one of the umami genes doesn,t work in cold temperatures. “It,s about zero degrees when they eat cold fish,”Zhang Jianzhi,the lead scientist, told the Daily Mail, so even if the penguins had a functional ( 功能的)gene, it might not work when they needed it.Second, penguins, tongues(舌头)are very special which may have something to do with their lack of taste. Instead of beingcovered with taste buds which help to taste food, penguins, tongues are very spiky.This is better for them to hold slippery(滑的)fish than tasting them. One study even showed that some types of penguins don't even have taste buds.However, penguins seem to be managing just fine.“Their behavior of swallowing food whole, and their tongue structure and function, suggest that penguins need no taste perception,” said Zhang.( )61. How many tastes do penguins have?A. FourB. ThreeC. TwoD. Five.( )62. From the passage, we can learn that.A.temperatures can decide the umami genes of penguinsB.the umami genes in penguins would work when neededC.penguins7 umami genes work well in cold temperaturesD.penguins7 tongues are very slippery( )63. The underlined word spiky means.A.圆滑的B.美味的C.钉子似的D.软绵绵的( )64. All of the following decide that penguins need no taste perception EXCEPT.A. they always swallow food wholeB. they live in cold temperaturesC. their tongue function is differentD. their tongue structure is special( )65. The study finds that .A.different penguins have their own favorite fishB. penguins have different genomes for the fivetastesC. penguins don,t have any of the five basic tastesD. penguins can,t taste the flavor of fish（八）In recent history, there have been some amazing inventions which have changed our lives.The plane has made international travel faster and easier. The Internet has brought people closer. And you must know the names of some famous inventors like Henry Ford and Steve Jobs. But there are many everyday objects which you probably don,t notice and you don,t know who invented them. Take for example Nils Bohlin, who invented he modern-day car seat belt （安全带）.Before 1959, only two -point seat belts were available, and the only people who often wore them were race car drivers. The two-point seat belt couldn,t protect passengers from internal injuries （内伤）during serious car accidents.In 1958, Bohlin joined V）lvo Car Corporation as a safety engineer. He came up with the three-point seat belt to keep passengers from flying out of their cars during collisions. The three-point seat belt used one strap 带子）across the chest （胸部）and another across the legs and then the two joined at the same place. Amazingly, this was a very simple idea which no one tried before.The three-point seat belt was introduced on Volvo cars in 1959. For more people's safety, Vblvo made the new seat belt design （设计）available to other car makers for free. Since then, engineers have worked to improve the three-point seat belt, but the basic design remains Bohlin,s.At the time of Bohlin,s death in September 2002, Volvo said that the seat belt had saved more than one million lives since it was introduced.（）61.The writer develops his ideas in Paragraph 1 by.A.telling a jokeB. giving some examplesC. asking some fun questionsD. describing a personal experience（）62.What can we learn about the two-point seat belt?A.It was sold worldwide.B. It was not easy to wear.C. It saved over one million lives.D. It was popular with race car drivers only.（）63.The underlined word “collisions” in Paragraph 3 means in Chinese in this passage.A.碰撞B.清洗C.制造D.修理（）64.Bohlin invented the three-point seat belt.A.in the early 1950sB. to get a job at VolvoC. while working at VolvoD. after having a car accident（）65.The best title of this passage is.A.Car safetyB. A great car companyC. A life-saving inventionD. Different kinds of seat belts（九）Artificial intelligence（人工智能），or AI in short, is the science of giving computers and machines ability to think and worklike humans. AI scientists and engineers have made a lot of cool technologies.AI is rapidly catching up with the human ability to read faces. As a result, facial recognition(识别)is used a lot in the world. Chinese police use this technology to identify criminals(罪犯).Once they caught a criminal when he attended a concert. It also checks the ID of ride-hailing(网约车)drivers and lets people pay for things with a smile.AI is also used in self-driving cars, which are believed to be the future of driving. Most drivers may wave or nod at passers-by to let them cross the street, but self- driving cars don,t have this ability. Car makers are testing a light signal system to help them “speak“ to humans. The system can show what self -driving cars will do. For example, if a driverless car is yielding(让路)，it will flash two white lights side to side. A rapidly flashing light tells passers-by that the car is about to speed up.Service Robots also show you how powerful AI is. Imagine this -- you come back home from school and your robot housekeeper iswaiting for you at the door. After dinner, he teaches you to play the piano, just like a real music teacher. Such thoughts will soon happen in the real world. In the future, more and more service robots will become good home helpers.AI is so powerful that it can help human beings and even replace us in many jobs.( )61.According to the passage, facial recognition is used for.A. driving cars.B. making people smile.C. calling the police.D. checking people,s information.( )62.The underlined word “identify” probably means in Chinese.A.减少B.鉴定C.消灭D.帮助( )63.In the future, a self-driving car may communicate with humans by.A. waving to themB. speaking to themC. nodding at themD. flashing lights( )64.Which technology is used in real life according to the passage?A. Service Robots at school. C. Facial recognition for payment.B.Robots as ride-hailing drivers. D. Light signals for self-driving car( )65.What can we learn from the passage?A.People use AI in many different ways.B.AI will take the place of human beings in all jobs.C.Self -driving cars will be able to talk like humans.D. A criminal was caught for inventing facial recognition.(十)When we see babies or pets, we can't help gently touching them to show our love. And they give us happy feelings back. But a recent stud y shows that it,s different for plants.A study, published in The Plant Journa shows that plants don,t like to be touched. That,s because touching changes their genes(基因)，and even worse, can slow their growth. Professor Jim Whelan in Australia gave an explanation. The lightest touch from a human, an animal, insect, or even plants touching each other in the wind, leads to a huge gene change in the plant.In order to test the theory, the scientists did an experiment on plants. They grew a number of plants to the age of four weeks. Thenthey touched them with a paintbrush every 12 hours over a 36-hour period. They found that as the result of the touch, the mitochondria(线粒体)in the plants had been partly destroyed. The mitochondria are the “power -hou se” of the cell(细胞).The mitochondriaproduce energy for the cells in both animals and plants. If this “power-house” is weakened, the plants will lose a large amount of energy that should have supported their growth.Whelan further explained, “If the touching is repeated, then plant growth is reduced by 30 percent.” Although the touching does have a strong influence on plants, usually the plants can still be alive. Touching changes the plants, but it's not always a bad change. Continually touching or moving plants will make them grow shorter than other ones. However, in some ways, this change could be helpful. It may help plants fight threats to their health such as insects and bad weather.The new research findings have led to a deeper understanding of the plants. And the research might help with the growth of plants.( )61.According to the article,can get in the way of plants, growth.A.loveB. touchC. waterD. weather( )62. How do the mitochondria support the plants, growth?A. By providing energy for cells.B. By changing the plants7 genes.C. By fighting against the insects.D. By reducing the amount of cells.( )63. The scientists did the experiment to.A.explain why pets love to be touchedB.find out why some plants grow more slowlyC.test if touching can change the genes of plantsD.show that plants' and animals' genes are different( )64. The underlined word “threats” means in Chinese.A.因素B.改变C.威胁D.对手( )65. The best title of this passage is.A.Touching has a bad influence on plantsB.New researches on plants and animalsC.Touching is good for plantsD.Touching changes the plants7 genesGetting the chance to hold a butterfly is a truly magical experience.Butterflies are shy, so you should consider yourself lucky if you get one to stay on your hand. Holding butterflies requires great care.Wash and dry your hands. Chemicals will do harm to butterflies, scales （鳞片），wings and bodies.So if you put on any sunscreen（防晒霜）before you go off to catch your butterfly, wash it off under the running water before touching them.Use sugar water.Butterflies have a sweet tooth.You may be able to get a butterfly to land on you without a net by making butterfly nectar （花蜜）.You can make butterfly nectar by mixing 4 parts water and 1 part sugar together.While watching butterflies near flowers or plants,put a little bit of the sugar water on your hand.They may soon be attracted by the sweet smell and fly to your hand to feed.Remain very still.Butterflies are very skittish and will get frightened （'惊吓）easily.If you want one to land on your hand and stay there for a while,be still and avoid any sudden movements.Be careful when holding a butterfly. While the butterfly is sitting on your hand,avoid petting it.Just try to watch its beauty without touching.Butterfly,s wings are covered in tiny scales.These scales give them their wing patterns （图 ^）,and make them more aerodynamic（流线型的）when flying.When you touch their wings, they lose scales.If they lose these scales, they can stillfly.However, the more scales they lose, the less aerodynamic they will be when flying.（）61.How many suggestions does the writer give on holding a butterfly?A.Three.B.Four.C.Five.D.Six.（）62.You should wash hands before holding a butterfly because.A.butterflies like clean hands C.sunscreen keeps butterflies awayB.it can stop people getting sick D.sunscreen is harmful to butterflies（）63.The underlined word “skittish” me ans in Chinese in the passage.A.仔细的B.谨慎的C.胆小的D.速度快的（）64.What is important for a butterfly to fly aerodynamically according to the last passage?A.Scales.B.Wings.C.Wing patterns.D.Body.（）65.What can be the best title of this passage?A.Magical Experience with ButterfliesB.Advice on Holding a ButterflyC.Fun of Playing with ButterfliesD.Ways of Holding a Butterfly.（十二）Do you find it difficult to put down your mobile phone?If yes, you,re not alone. These days, many people are facing the stress in the use of mobile phones. They reach for their mobile phones when they wake up in the morning, and keep checking their social media apps to get the latest updates(更新).A report from Go ogle shows that 70 percent of people don,t want to spend much time on their phones. This is why Google introduced an app called Dashboard for the new Android operating system(安卓操作系统).This new app includes functions(功能)that help users manage the time. For example, users can see how many times they,ve unlocked their phone, how many times they,ve checked their social media apps, and how much time they spend on each app every day.Once the users see this information, they,ll be able to make some changes. Wit h the App Timer(计时)function, users can set a time limit for how long they can use each app for every day. After they,ve hit the limit, they won,t be able to use the app until the next day. And with another function, the app gets incoming calls silent when the user puts the phone face down.If people truly want to make full use of their free time instead of losing hours on their phones, these new functions are just one way of doing that.After all, who needs to use an app to stop you from using other apps? The easiest answer would be just to use your willpower.( )61. The users' stress comes from.A.too many updates of the apps C. too much information they receiveB.too many functions of the app D. too much time they spend on the phone( )62. Which of the following is NOT included in Dashboard,s functions?A. It stops the users from using their willpower.B.It checks how much time the users spend on apps.C.It lists how many times the users have unlocked the phone.D.It shows how many times the users have checked social media apps.( )63. T he underlined word “limit“ in Paragraph 4 mean s in Chinese.A.目的B,标准 C.许可 D.限制()64. What does the writer think of Dashboard?A.Its design is perfect. C. It needs more functions.B.It may be helpful to some people. D. It has too many functions.( )65.What,s the main idea of the passage?。
