2019-2019学年度山东省滕州市张汪二中周末提优卷九年级英语试题(2019年12月6日)一、完形填空The bicycle is one of the simplest yet most useful inventions in the world. What is most surprising is that it was not invented earlier, although the great_____Leonardo da Vinci had drawn pictures for bicycles and also for flying machines and some other things. Those things were not_____until long after he died.A person riding a bicycle uses very little energy to make the bicycle move, and there is no_____at all when you are riding. Even so, in developed countries, most people don’t travel to work by bicycle. It is not _____the bicycles are expensive or people feel tired if they_____to work. It’s because the n umber of cars on the roads becomes larger. It certainly becomes more _____to ride a bicycle. As a result, more people _____their bicycles away and go to work in their cars, and_____,the situation is made more serious. Perhaps the best way to make riding_____and more popular is to create paths(开设通道)only for bicycles, and to make it so difficult and expensive for drivers to take their cars into the city that they will go back to______their bicycles.1., A.teacher, B.inventor, C.engineer, D.musician2., A.changed, B.produced, C.protected, D.collected3., A.pollution, B.oil, C.air, D.help4., A.since, B.as, C.like, D.because5., A.make, B.play, C.ride, D.take6., A.typical, B.certain, C.strange, D.dangerous7., A.put, B.get, C.give, D.send8., A.all in all, B.as for, C.in this way, D.or so9., A.safer, B.slower, C.faster, D.better10., A.sell, B.fix, C.use, D.clean, 二、阅读理解Many children spend a lot of time watching or playing with electronic media –from televisions to video games, computers and other devices(设备).So, it is natural that parents should wonder about the time children spend looking at a TV or computer screen. Americans say “screen time” when they talk about any time children spend in front of an electronic device. Perhaps parents can stop worrying so much about screen time, at least for older boys and girls. In October 2019, the American Academy of Pediatrics (AAP) listed several suggestions for parents and child care workers. Here are some of the suggestions.λ Avoid digital media use in children younger than 18 to 24 months.λ For children aged 18-24 months, avoid letting the child watch media alone. And avoid using media as a way to comfort your child.λ For children two to five years of age, allow one-hour screen time on “high-quality(质量)programming” a dayand watch it with your child.λFor children aged 6 and older, don’t spend too much time using media. Also, make sure that screen time does not take the place of healthy sleep, exercising, doing homework and other activities.λ Make sure to have media-free time together as a family, such as dinner or driving. Also make some areas of the home media-free. Turn off you child’s electronic devices an hour before bedtime.11.What is “screen time” according to Americans?A.A kind of timing system(系统).B.A survey on electronic mediaC.Any time children spend in front of electronic media.D.Any electronic device children like to play with12.What did AAP do in 2019 after?A.They gave some practical suggestions.B.They told parents how to reduce their children’s screen time.C.They trained many child care workers.D.They raised much money to stop children using electronic devices.13.How do parents deal with the screen time for children two to five years of age?A.Choose proper programs and watch with them., B.Play with them for at least one hour.C.Avoid letting them watch TV., D.Don’t worry about th em.14.How does AAP explain too much screen time?A.An hour or more every day., B.Using too many electronic devices.C.Screen time takes the place of other activities, D.Using electronic media to comfort the children.15.What is media-free time?A.It is the time you can use media freely., B.It is the time you cook or drive.C.It is the time to be with your family., D.It is the time you stay away from electronic devices.An invention in front of your eyesWhat is the most important invention of all time? Is it the written word that helps us to record information? Is it the telephone that lets us talk to people from all over the world? Is it the car that lets us travel at great speeds to meet others? Umberto Eco, an Italian writer, thinks it is something quite different. He says the most important invention might be bright in front of your eyes. He is talking about a simple pair glasses.Modern eye glasses were invented around 1000 years ago. They were more than just a convenient way to read. Before glasses, writers, scientists or teachers who could not see properly had to memorize everything. After about ten years of poor eyesight, they could not remember well enough and could not work. Glasses meant that people could work in their old age.People who wanted to remember some information could write it down and read it. Eye glasses are one of the world’s greatest inventions and were probably worn by the people who designed the first telephones and cars.16.The invention of the written word is important because___________.A. we need it to listenB. we need it to record informationC. we just need it to read17.The author thinks _______ is the greatest invention of all time in his passage.A. the telephoneB. the carC. a simple pair of glasses18.Before glasses were invented, writers, scientists and teachers had to_________.A. memorize everythingB. write down everythingC. read everything19.What happened after glasses were invented?A. people could not remember well enough.B. people could not remember well enough.C. people could write down some information and read it.20.From this passage, we can know __________.A. modern eye glasses were invented 100 years agoB. people who designed the first telephones and cars probably wore those glassesC. the author of this article is an AmericanThe car was invented just a century ago. You may know all kinds of cars’ names, but many people don’t know who was the inventor of the first car.The first car was invented not by an Englishman, but by an American. His name was Henry Ford.Henry was born in a poor family. He was the eldest of the six children. When he was a boy, he became interested in watches and machines. When he was twelve years old, his mother died. Soon he had to work in a machine shop for two dollars and fifty cents a week.In the evening, he repaired watches for another dollar a week. The hard life made him strong and able.At that time, there was another interest in the life of the young Ford. He wished of making a machine.It could run without horses, so named horseless carriage. He overcame a lot of difficulties and in April 1893, the “horseless carriage” was invented at last. It was the first car.Later Henry Ford founded the Ford Motor Company. He was really the first inventor of the car in the world. 21.Who really invented the first car?A.A Chinese., B.An Englishman., C.A Russian., D.An American.22.From this story we can know the car was invented _____.A.only one hundred years ago, B.less than one hundred years agoC.more than one hundred years ago, D.long long ago23.Henry Ford must have _____.A.five brothers and sisters, B.six brothers and sistersC.five younger brothers, D.five younger sisters24.How many dollars did young Ford get every week?A.2.5 dollars., B.1.5 dollars., C.3.5 dollars., D.3 dollars.25.Henry Ford invented the first car _____.A.with his brothers, B.without any difficultyC.himself, D.difficult, 三、根据对话内容,从方框内所给的选项中选出能填入空白处的最佳选项。

And the electricity can then either be stored or used to charge a mobile immediately(立即).He said, “With each rotation(旋转) of your hand, the gyroscope's speed increases quickly and produces more power. The average(平均的) speed of the gyroscope is about 5,000 rounds per minute. With this small charger, your physical energy can be turned into electrical energy and this means you can charge your phone. ”Hand Energy can help you produce endless electricity. You can use it everywhere you want. It is especially useful for people who have to spend a long time in the wild. What's more, it's friendly to the environment and helps you to exercise your wrists. It takes between 40 minutes and one hour to fully charge the batteries(电池) in Hand Energy.The invention took Vaga a year to develop. Now, the inventor from Minsk, Belarus, is ready to put it into production and send out the creative convenient chargers.21.The energy of the new charger comes from ________.A.the sun, B.your body, C.the batteries, D.your phone22.If we want to produce energy with the charger, we should ________.A.shake our hands, B.move quicklyC.go to the wild, D.charge our phone23.Who will be the most interested in the invention?A.The teachers., B.The medical workers.C.The drivers., D.The field workers.24.It is not clear whether ________ or not, according to the passage.A.the more you shake, the more power it producesB.the charger helps to protect the environmentC.we can buy the charger online in ChinaD.it will produce endless electricity25.Which of the following could be the best title of the passage?A.A wonderful invention, B.A great inventorC.An interesting story, D.A piece of exciting newsMany children spend a lot of time watching or playing with electronic media –from televisions to video games, computers and other devices(设备).So, it is natural that parents should wonder about the time children spend looking at a TV or computer screen. Americans say “screen time” when they talk about any time children spend in front of an electronic device.Perhaps parents can stop worrying so much about screen time, at least for older boys and girls.

Here are some of the suggestions.λ Avoid digital media use in children younger than 18 to 24 months.λ For children aged 18-24 months, avoid letting the child watch media alone. And avoid using media as a way to comfort your child.λ For children two to five years of age, allow one-hour screen time on “high-quality(质量)programming” a day and watch it with your child.λ For children aged 6 and older, don’t spend too much time using media. Also, make sure that screen time does not take the place of healthy sleep, exercising, doing homework and other activities.λ Make sure to have media-free time together as a family, such as dinner or driving. Also make some areas of the home media-free. Turn off you child’s electronic devices an hour before bedtime.26.What is “screen time” according to Americans?A.A kind of timing system(系统).B.A survey on electronic mediaC.Any time children spend in front of electronic media.D.Any electronic device children like to play with27.What did AAP do in 2016 after?A.They gave some practical suggestions.B.They told parents how to reduce their children’s screen time.C.They trained many child care workers.D.They raised much money to stop children using electronic devices.28.How do parents deal with the screen time for children two to five years of age?A.Choose proper programs and watch with them., B.Play with them for at least one hour.

Give them a taste of the online cartoon show,and you'll finally find the children learn it happily and relaxingly.11.The phrase “help children start seeing green” can be replaced by “________”.A.help children see the green colorB.tell children they should like greenC.help children understand the importance of eco-friendly livingD.teach children how to recycle rubbish12.How many suggestions does the writer mention in the passage?A.Three., B.Four., C.Five., D.Six.13.The Chinese meaning of the underlined word “recyclables” is “________”.A.可回收利用物, B.再生能源, C.化学药剂, D.电缆线14.According to the passage,which of the following is NOT true?A.We can buy toys made from wood.B.Parents shouldn't teach children environmental subject at home.C.Most kids don't like to learn subjects on the environment.D.Parents should teach their children to build a birdhouse.15.The writer doesn't think that ________.A.parents should buy lots of toys for their childrenB.parents should give unloved toys to the libraryC.parents can teach children environmental subjects on TVD.parents should spend time in nature with their childrenAmerican researchers have successfully developed a way to clean waste water without chemicals. The technique uses green plants. The tests were carried out at a waste water treatment centre. The scientists put plants in narrow containers inside a glass building. One end of each container was a little bigger than the other end. Waste water was directed down the container through the plants' thick roots which absorbed the wastes in the water and used them for food. At the same time the plants produced natural gas.The gas could be collected and sold as fuel. Four places in Florida are using green plants to clean their waste water.16.The best title for this passage is______.A.The Success of American ScientistsB.A New Way to Treat Waste WaterC.Waste Water and Green PlantsD.Advanced Technology in America17.The technique to clean waste water is based on the fact that ______.A.green plants can be put in narrow containersB.most green plants have thick rootsC.water can be directed down through the plants' thick rootsD.the wastes in water can be food for plants18.The technique is called a new way because ______.A.it is cheaper than any other oneB.it can be carried out in a glass buildingC.it makes waste water clean but uses no chemicalsD.it needs only narrow containers and green plants19.The new technique ______.A.has been widely used in AmericaB.is still being tested since its first useC.proves to be more valuable than expectedD.has now come into use in some places of America20.What is the main idea of this passage?A.Green plants are successfully used to clean waste water.B.Scientists are able to clean waste water.C.Green plants have been used to clean waste water in Florida.D.New ways of making waste water clean are better than ways of using chemicals.April Fool’s Day is supposed to be a day to play jokes on others in the hope of getting a good laugh and making one feel like a fool.However,the April Fool’s Day of 1989 was quite different for my mom and me.That day my friend Jimmy and I were playing a game.I had dropped down from a bar(横木)many times in the past without ever having a problem,but that day the simple act of dropping to the ground became a nightmare(噩梦).I broke my arm.Jimmy’s dad heard my crying and rushed out to see what was going on.When he saw the problem,he quickly put me into his truck and went inside to telephone my mom and let her know he would take me to the hosp ital.As that day was April Fool’s Day,Mom was not buying it and really thought all this was a big joke.Mom was finally convinced by Jimmy’s mom.When she saw me,she broke down in tears because she felt so bad—she originally thought this was just a big prank(恶作剧).I guess one could compare this to the story of “The Boy Who Cried Wolf”.Since I had pulled pranks before,it is no wonder that my mom didn’t believe it.I as well as my mom was made to look like a fool that day.We both learned a valuable lesson.21.Wh at happened to the writer on the April Fool’s Day of 1989?A.He dreamed a terrible dream., B.He was hurt by Jimmy.C.He had an accident., D.He fooled his mom with his friend.22.Why did Jimmy’s dad phone the writer’s mom?A.Because he wanted to play a joke on her.B.Because he wanted her to go to the hospital to pay the money.C.Because he wanted to see how deeply she loved her son.D.Because he wanted to inform her of the accident.23.What does the underlined sentence “Mom was not buying it” mean?A.She di dn’t believe what Jimmy’s dad said.B.She would not like to pay the money.C.She had no preparation for the bad news.D.She thought her son deserved(应受)it.24.Why did the writer mention the story of “The Boy Who Cried Wolf”?A.Because he thought it was his mom’s fault.B.Because he had a lesson like that.C.Because he was proud of his story.D.Because he felt he was luckier than that boy.A.the writer’s mom didn’t care much about him, B.the writer was a dishonest personC.the writer won’t pull pranks as before, D.the writer will lose interest in games, 三、阅读短文,从短文下面方框中的六个句子中选择五个还原到短文中,使短文通顺完整,衔接自然。
