2019中考英语阅读理解选习题（5）及答案Passage A（2019中考保健与健康类选练）Almost every day, we discuss the topic of health, especially for kids. But what is health? “Health”means eating well, getting enough exercise, and having a healthy weight. Let’s read the following rules. They can help you stay healthy.(1) Eat a variety of food, especially fruit and vegetables. We all know that eating fruit andvegetables can help us stay healthy, but many of us only eat our favorite food. Remember that we can only get the nutrition(营养) we need by eating different kinds of food, espe cially fruit and vegetables.(2) Drink water and milk most often. Everyone knows that water is important. Besides that, kidsneed plenty of calcium(钙) to grow strong bones, and milk is rich in it. Every day, you should drink at least three cups of milk, when you are 9 years old or older. You should also try to have less sugary drinks, like soda and coca. They include a lot of sugar. Sugar only includes calories(热量), not important nutrition.(3) Listen to your body. When you are eating, notice how your body feels. When your stomachfeels comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can make unhealthy and fat.(4) Limit screen time. What’s screen time? It’s the amount of time you spend watching TV,movies and playing computer games. The more time you spend on these sitting-down activities, the less time you spend playing sports, like basketball, and doing other activities like riding and swimming. Try to spend no more than 2 hours a day on screen time.1. The underlined phrase “a variety of” means ___________.A. plenty ofB. all kinds ofC. the rest ofD. a lotof2.

Health is very important.参考答案1B 2D 3D 4CPassage B中考英语阅读理解分类练习：健康保健类You may know the saying: An apple a day keeps the doctor away. A recent study by the Chinese University of Hong Kong has discovered another saying: An apple a day keeps old age away.The study involved fruit flies(g果蝇), as they share many genes(基因) with humans. Researchers gave one group of fruit flies normal food, and another group of fruit flies got the same food including apple.The results showed that flies that ate apple lived an average of 55 days longer than the flies that didn’t eat apple. The study also found that apple-eating flies were more able to walk, climb and move about as they became old, the Journal of Agricultural and Food Chemistry reports.The researchers believe that the antioxidants (抗氧化剂）found in apples are good for health.In another experiment, researchers studied the diets of thousands of women. They found that those women who often ate apples were 20 percent less likely to have heart disease.Sc ientists have recently discovered the apple’s genetic code(基因代码). This allows scientists to make new kinds of fruit that are healthier. Researchers are already using this information to grow apples with added antioxidants. Antioxidants help to keep eyes and joints (关节)healthy and protect against heart attacks and cancer.Apples that help people lose weight may be in supermarkets in just four or five years. They are said to be “extra healthy” apples that can stop people from overeating.【小题1】Fruit flies were used in the research because_______________ .A．they love to eat applesB．they share similar genes with humansC．they are easy to catchD．they can live longer【小题2】By studying the diets of many women, researchers ___________ .A．proved apples were good for people’s health.B．found they are healthier than menC．helped them to lose weight successfullyD．discovered the genetic code of the apple【小题3】From the story, we can infer(推测) that _________________.A．women like to eat apples more often than menB．people who eat apples are easier to have heart diseaseC．scientists are studying a new type of applesD．apples’ genetic code is similar to other fruits【小题4】 You may find the passage in ____________ .A．a science magazine B．a guidebookC． a picture show D．a storybookPassage CNow satellites are helping to forecast（预报）the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere（大气）, because this is where the weather forms（形成）. They send these pictures to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare（比较）them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.So the weather satellites are a great help to the meteorologists. Before satellites were invented,the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead（提前）.1. Satellites travel _____________.A. in spaceB. in the atmosphereC. above the groundD. above space2. Why do we use the weather satellites to take pictures of the atmosphere? Because __________.A. the weather satellites can do it easilyB. clouds form thereC. the weather forms thereD. the pictures can forecast the weather3. Meteorologists forecast the weather __________.A. when they have received satellite picturesB. after they have compared new satellite pictures with earlier onesC. before they received satellite picturesD. during they study satellite pictures4. Maybe we’ll soon be able to forecast the weather f or ________.A. one dayB. two daysC. five daysD. seven days or even longer5. The main（主要的）idea of this passage is that satellites are now used in _________.A. taking pictures of the atmosphereB. receiving pictures of the atmosphereC. doing other work in many waysD. weather forecasting参考答案Keys: 1-5 ACBDDPassage D（2019中考保健与健康类选练）Running is becoming popular these days. Many of us run for our health. Doctors say many of thehealth problems come from these bad habits: eating too much, drinking too much, smoking, and not taking enough exercise. Doctors tell us, "Eat and drink less, don't smoke, and exercise more."Running is a good form of exercise because it helps build a strong heart. It also helps most people lose weight. One 68-year-old woman runs thee times a week. She runs to lose weight. "I love to eat,"she says.Running is good for health in other ways, too. Many runners say running keeps colds and other small health problems away. "Running is my doctor," says one man.

But if we consider the situation of the young people aged from eight to eighteen, we should think again.What we often see nowadays is that young people juggle a larger number of electronic devices (电子产品) as they study. While working, they also surf on the Internet, send out emails, answer the telephone and listen to music on their iPods. In a sense, they are spending a large amount of time in fruitless efforts (努力) as they multitask.Multitasking is even changing the relationship between family members. As young people give so much attention to their own worlds, they seem to have no time to spend with the other people around them. They can no longer greet family members when they enter the house, nor can they eat at the family table. Multitasking also has an effect (影响) on young people’s performance at university and in the workplace. When asked about their opinions of the effects of modern gadgets (器具) on their performance of tasks, many young people gave a positive (肯定的) response (回应). However, the response from the worlds of education and business was not quite as positive. Educators feel that multitasking by children has a serious effect on later development of study skills. They believe that many college students now need help to improve their study skills. Similarly, employers (雇主) feel that young people entering the job market need to be taught all over again, as modern gadgets have made it unnecessary (没必要) for them to learn special skills to do their work.1. What does the underlined word “juggle” most probably mean?A. Want to buy.B. Use at the same time.C. Take the place of.D. Search information from.2. In Paragraph 3, the author points out that__________.A. family members do not greet each otherB. family members do not eat at the family tableC. young people get on well with their familiesD. young people hardly communicate with their family members3. What’s the main idea of the last paragraph?A. Young people must learn skills for future jobs.B. Young people benefit (获益) a lot from modern gadgets.C. Multitasking is an important skill to young people.D. Mul titasking influences young people’s development seriously.4. Which of the following is TRUE according to the passage?A. Young people think multitasking is good for their study and work.B. Employers consider it unnecessary for young people to be taught all over again.C. Educators feel that young people don’t need to improve their study skills.D. People from the world of education believe multitasking has a good effect on children’s later study skills.5. The author develops (阐述) the passage mainly by__________.A. providing special examplesB. following the natural time orderC. giving out a cause and analyzing (分析) its effectsD. comparing opinions from different worlds参考答案BDDAC。

Have you ever had dreams about building a robot? Or puttingtogether a spaceship? Or even seeing your face made out ofchocolate? Done. All you need is a 3-D printer!The possibilities of 3-D printing seem endless. All the user has to do is to designan object on the computer and choose a material to print in. The printers print in hundreds of different materials including glass, sugar and even skin! When the user presses “print”, the 3-D printer spreads the material layer(层) by layer and like magic the object is produced.The first 3-D printer was invented in 1986 by an American, Charles Hull. But 3-D printing has only become cheap enough recently for most people to use. Designers now use 3-D printing to create unusual things. The Dutch artist Dirk Vander Kooj prints furniture made from old fridges. And doctors have used 3-D printing to print human body parts! The Telegraph reported in February that scientists from Cornell Medical College even printed a man-made ear.But like a lot of new technologies, if 3-D printing gets into the wrong hands, it can be dangerous. In 2011 a group of four men in the US used 3-D printing to produce ATM skimmers (提款机盗刷器). These were placed on an ATM and stole over $400,000 from users of the ATM. It is terrible to think that criminals like them might one day use a 3-D printer to print a gun.But for better or for worse, 3-D printing has been put into use. In a few years, you’ll probably be wondering how you could ever live without your 3-D printer! （）1. _____ invented the first 3-D printer.A. Charles HullB. Dirk Vander KoojC. A doctor called CornellD. Four men in the U.S（）2. What is the correct order for people to use a 3-D printer?A. Choose a proper material.B. Press the print button.C. The 3-D printer spreads the material.D.

九全Units13--14一、阅读理解The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70%of the earth's surface is covered with water. But about 97%of that is sea water or salt water. Man can only drink and use the other 3%of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain（酸雨）, is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won't have enough dean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water i~ used only once and then sere out into a sewer system（下水道）. From there it returns to the sea or goes underground.But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won't be used up.1. The world is thirsty for water because______.A．we don't have enough fresh waterB．a lot of water goes into sewer systemsC．only 70% of the earth's surface is waterD．sea water is widely used rather than fresh water2.
