you learned in your first Chinese class in primary school was probably pinyin.The year2018marks pinyin's sixtieth birthday.In1958,Chinese linguist(语言学家)Zhou Youguang and his team designed pinyin.Before that,Chinese people used many other methods to denote(标注)the pronunciation of Chinese characters.In ancient China, people denoted Chinese characters using other Chinese characters that had the same pronunciation.Some of the symbols are Chinese character strokes(笔画)．For example,a vertical stroke(一竖)pronounced as“i”in pinyin.Some people in Taiwan still use this method.However,these methods are not as simple as pinyin.Because of pinyin,many illiterate(不识字的)people have learned how to read.We use pinyin to type Chinese characters into computers and phones.Pinyin has been useful in other ways,too.It helps to promote the use of Standard Chinese,or Mandarin, so people who speak different dialects(方言)can still understand each other.Pinyin is not only popular in China.Many people around the world start to learn Chinese by learning pinyin.You might say“nihao”instead of “hello”to a foreign friend.The Oxford English Dictionary(《牛津英语词典》)includes more than100Chinese words in pinyin,such as zhongguomeng for“Chinese dream”，and wanggou for“online shopping”．Pinyin is not only a language tool,but also a cultural bridge that connects China to the world,Guangming Daily noted.Pinyin is still young.But it has been and will still be a useful tool in the future.()6.The underlined word“promote”in the second paragraph may mean“________”in the

introduce our English language holidays for you.As English is one of the most widely spoken languages in the world，millions of people look forward to studying English abroad(在国外)during holidays.English language holidays are taken in Englishspeaking countries like England，the USA，Australia and so on.There，you study in a language school with students from many different countries.You live with local(本地的)people，and often stay with a host family.The English language holiday has become a very popular way of learning English because it has many advantages.●Constant Experience(持续的体验)Because you are in an Englishspeaking country，from the time you wake up and have breakfast with your host family until late evening，you have no opportunity to escape the English language.●Mixed(混合的)ClassesOn a language holiday，students come from all over the world.It is possible that nobody in your class will speak your language，so you will just have to speak English.●Free From PressureOn a language holiday，you may forget the everyday pressure of school.You feel more relaxed and you can learn easily.●Cultural UnderstandingLearning a language is not only about learning words.Different countries have different cultures.People think and behave(表现)differently.By visiting and living in a foreign country，you learn to understand the culture and the people，and so understand the language better.If you want to know more about it,don't forget to attend our introduction meeting on time.It will be held at eight tomorrow morning in our school hall.You won't realize its advantages until you experience it by yourself.()1.The followings are all Englishspeaking countries EXCEPT ______according to the passage.A.EnglandB.the USAC.RussiaD.Australia()2.While you are

photos，call a Didi Taxi，send short messages or emails，check emails，surf the Internet and watch videos almost anywhere.Especially，smartphone shopping has become more and more popular in our life because people can buy almost everything they need there.You are wondering how to shop on smartphones?Let me show you.If you live in the central part of the city,and you need to buy some fresh grapes from the east of the city,you can use your smartphone.To start with，all you need to do is download a shopping app(应用程序)and find a suitable store you like.Shopping on the smartphone has a lot of advantages，of which the most important is perhaps its convenience.People don't have to waste a lot of energy and time to go from one shop to another to choose things they like.This is especially good

It does, however, have its own problem.Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rulesrequire that a race walker’s knees stay straight through most of theleg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such anattractive activity, however, says Jaclyn Norberg, an assistantprofessor of exercise science at Salem State University in Salem, Mass.Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon amo ng race walkers. But thesport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to becautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.4. Why are race walkers conditioned athletes?A．They must run long distances.B．They are qualified for the marathon.C．They have to follow special rules.D．They are good at swinging their legs.5. What advantage does race walking have over running?A．It’s more popular at the Olympics.B．It’s less challenging physically.C．It’s more effective in body building.D．It’s less likely to cause knee injuries.6. What is Dr. Norberg’s suggestion for someone trying race walking? A．Getting experts’ opinions.B．Having a medical checkup.C．Hiring an experienced coach.D．Doing regular exercises.7. Which word best describes the author’s attitude to race walking? A．Skeptical. B．Objective.C．Tolerant. D．Conservative.CAn unconventional method for growing rice has been found to increase yields(产量) by 20 to 50 percent. Reports from China, India, Southeast Asia and Africa suggest that average yield increases of 20 to 50 percent are regularly being achieved by farmers adopting the "system of rice intensification(集约化)"(SRI)，which needs one-tenth as many seeds and aims to stimulate the root system of plants rather than trying to increase yields in the conventional way by using improved seeds and fertilizers.The idea of using less to gain more is seen as an important innovation(革新) for adapting farming to climate change and a way to increase yields at a time when human populations are growing fast but traditional plant breeding and genetically modified techniques have failed to increase yields more than a few percentage points, says Norman Uphoff, professor of international agriculture at Cornell.The new way to grow rice needs only half as much water, and is proving most popular in water-stressed countries, says Tavseef Mairaj Shah, a Ph.D．researcher. "Rice growing in Kashmir largely depends on irrigation systems that draw water from the river Jhelum. But climate change is leading to drier winters, untimely rains, and warmer summers."“SRI is a great technique, not just from the water-savingperspective but because it offers better yields and soil conditions. Different studies, both at the experimental level and farmer-participative level, have shown that SRl improves yields with less water.” Shah adds.Some academic, the global seed industry and the international community once rejected reports of “fantastic” yields, accusingfarmers of falsifying(篡改）records and researchers of carelessness and "non-science". But more than 600 articles, checked by SRI Internationalat Cornell University, have shown benefits.Uphoff says, “Attitudes are changing.The original hostility(敌意)has gone." However, the early opposition has resulted in comparativelylittle scientific research being conducted into SRI and a slow understanding by funders.8. How does SRI increase the yields of rice?A．By sowing more seeds B．By using improved seeds.C．By improving its root system. D．By adopting special fertilizers. 9. Compared with the conventional method for growing rice, SRI.A．needs less water B．increases labor costsC．requires better soil conditions D．depends on genetically modified techniques10. What was the global seed industry's initial attitude toward reportson SRI?A．Curious B．Skeptical. C．Approving D．Uninterested. 11. Which of the following can be the best title of the passage?A．How to Increase YieldsB．People's Attitudes Towards SRIC．An Innovative Means of Growing RiceD．The Disadvantages of Conventional Plant Breeding二、完形填空A Florida man likes to shop at garage sales for old plaques(纪念匾)so he can reuse the wooden backs.

When people find I’m a polyglot(通晓多种语言的人)，they always ask me,“How do you do that?” Honestly, my answerwill be, “I don’t know. I simply love learning languages.” 32 They want to know why they spend years learning even one language, never achieving fluency, and what’s the secret of being polyglots.33 And what do we have in common? I decided to find that out. I went to several events where language lovers gather to practice their languages, asked dozens of polyglots about methods they use, and heard dozens of approaches. Everybody seems to have a unique way to speak several languages fluently.34 All these polyglots talked about language learning as if it was great fun. They found ways to turn language learning from aboring subject into a pleasant daily activity. You should have seentheir faces when they were showing me their colorful grammar charts and handmade flash cards. 35 The methods are various, but they make sure it’s something enjoyable.I realized it’s actually how I learn. 36 Then interesting programs became my choice. So all is clear. If you don’t like writing words down on paper, type them in an app. If you’re a shy perso n, apply self-talk at home. This is how polyglots learn languages, and the best news is that it’s available to anyone willing to take the learning into their own hands.A．How can those with little talent be fluent?B．But people are never happy with the reply.C．There’s no shortcut to learning languages for anyone.D．One of them even made recipes in a foreign language.E．That made me wonder, too, how other polyglots actually do it. F．When learning Spanish last year, I was bored with textbooks. G．Polyglots simply found ways to enjoy the language-learning process.四、语法填空阅读下面短文, 在空白处填人1个适当的单词或括号内单词的正确形式.May 21st this year marks the first International Tea Day, which37 (name) by the United Nations on November 27th, 2019.

高三英语晚自习限时训练一、阅读理解AFun things to do in high schoolLearn another languageYour school might be holding foreign languages classes, so this is a great way to start your language learning journey! If you want more self-paced learning, apps like Duolingo are easily accessible (可使用的) on our mobile phones. As our world becomes more in terconnected, it’s always good to learn another language or two.Aim for a semester (学期) of straight AThis can be a difficult task but not impossible to achieve, as long as you put in the right amount of work and effort. If you are struggling(挣扎)with your grades, you can host or join group studies with your classmates!Don’t be disheartened if you are not able to get an A in a semester. What’s important is having the drive to go forward. As a famous person once said, “He who would climb a ladder must begin at the bottom.Experience another cultureCulture and tradition are something that all humans share. No matter where we come from, we always bring our culture with us. People coming from different cultures may be among your friends or neighbors.You can go to a museum, read a book, or try new food in your area.

Not only will this make their stomachs happy, but you’ll also bond (联系) the whole class together. Just don’t forget to check with your teacher first before bringing one.1. What should you do if you want to learn a language at your own speed?A．Go to a museum to read books. B．Attend another language class. C．Learn it on an app like Duolingo. D．Join group studies with your classmates.2. What’s the key if you can’t get an A in a semester?A．Keeping an open mind. B．Asking your teachers for help. C．Changing your study method. D．Having the drive to go forward.3. What will probably be the result if you bring a treat to class?A．Experiencing different cultures. B．Making your teacher angry and anxious.

But it’s not clear that these benefits come specifically from vitamin C．The Age-Related Eye Disease Study found that a daily supplement containing 500 mg of vitamin C can help slow the progress of macular degeneration, an age-related eye disease that causes vision loss. But we don’t know what benefits, if any, are provided by vitamin C in particular.Many people take vitamin C supplements in unnecessarily high doses to prevent or treat various conditions for which its effectiveness is unproved. The vitamin C supplements have variously been said for staving off sunburn and improving the appearance of wrinkles. None of these benefits have been confirmed in scientific studies.Perhaps the best-known and most widely promoted use of high-dose(高剂量)vitamin C is to prevent or treat the common cold. Most of the evidence shows that high-dose vitamin C will, at most, shorten a cold by one day. In ordinary circumstances, vitamin C has no preventive value, although a few studies have reported a 50% reduced risk of developing colds among people taking vitamin C in extreme circumstances-for example, skiers, marathon runners, and soldiers working in extreme conditions.The recommended vitamin C dosage per day for healthy women is 75 mg per day. For adults, the highest safe daily intake is likely to be 2, 000 mg per day. Vitamin C is water-soluble, so any amount more than you need will not be stored in the body. It’s safe in almost any amount from foods, and supplements in recommended amounts are also regarded as safe for most people. In some people, high doses-more than, say, 2, 000 or 3, 000 mg per day-can cause a variety of symptoms. People with kidney conditions should take no more than 1, 000 mg a day.；4. What can we learn about vitamin C in the first paragraph?A．It can be of better effect in higher doses.B．It can be a cure for age-related eye disease.C．It can help slow the progress of some illness.D．It can reduce the risks of the mouth cancer.；5. What function does vitamin C have intreating the common cold?A．It can help people save plenty of money.B．It can stop soldiers from catching a cold.C．It may reduce a cold by one day at most.D．It may prevent the common cold efficiently.；6. How much Vitamin C are healthy women advised to take per day?A．75 mg.B．500 mg.C．2, 000 mg.D．3, 000mg.；7. Where is this text probably taken from?A．An exam paper.B．A travel journal.C．An art guidebook.D．A science magazine.CThis year will have been the warmest in the UK, the Met Office has said. Although for many people the record from the year that attracted the most attention was that the summer heatwave reached 40. 3℃, the organization said that more significant was a figure 30 degrees lower-the average temperature over the course of the year.Although the exact temperature will need to be confirmed in the new year, the Met Office predicted that 2022 is going to exceed (超过)the previous record for the warmest annual average, which was 9. 88C in 2014. Apart from this month, every other month in the UK in 2022 was warmer than average. New Ye ar’s Day 2022 was the warmest on record, exceeding 16℃ in North Wales. Dr. Mark McCarthy, head of the National Climate Information Centre, said: “While many people will remember the summer’s extreme heat, what hurts people most, especially the elderly, this year is the relatively consistent heat through the year. ” Although this summer was the fourth warmest on record, it was the first in which the temperature exceeded 40℃.McCarthy said that we can expect to see increasingly warmer summers as a consequenc e of climate change. “The warm year is in line with the impacts we expect as a result of human-related climate change, ”he said. “Although it doesn’t mean every year will be the warmest on record, climate change continues to increase the chances of increas ingly warm years over the coming decades. ”Rebecca Newsom, head of politics at Greenpeace UK, said: “These aren’t the kind of records you want to be breaking. Record-breaking investment in the renewable technologies will get us out of this mess.At present though, Britain is ready for rain, with forecasters warning of difficult driving conditions caused by wet weather over the next few days. Although temperatures will stay mild for much of the UK, the Met Office warned that the rainfall will hit England and Wales this Saturday and Sunday.；8. What will make this year special in the UK?A．The most visitors will be attracted.B．The warmest year will take place.C．The biggest success will be achieved.D．The highest temperature will be 30℃.；9. What can be inferred from Paragraph 2?A．Every month in the UK was warmer than average.B．Next summer may be the first summer to exceed 40℃.C．Many elderly men may go to hospital for the high heat.D．New Year’s Day was the warmest on record in England.；10.

I have, however, struggled to think of an answer. Yes, we do have our own national dishes. 12Fish and chips, as you could guess, is made up of battered fish and chips. It is often accompanied by mushy peas (豌豆糊), which consists of peas mashed up to form a thick paste. The majority of British people really do love this dish but it is not something that we would eat, say, on a weekly basis. 13 British people associate this dish with the seaside and it’s something that will usually be eaten on a day trip there.14 This is made up of roast meat, usually chicken or beef, accompanied by roast vegetables and a meat sauce. It is usually eaten on a Sunday, perhaps for a special family dinner.Although we do have our traditional dishes, we do not eat these on a daily basis. On a daily basis many British people will eat rice or pasta dished. 15 You can see this by looking at the range of international foods in the supermarket or at the va riety of different restaurants you can find on our high streets.16 However, perhaps unlike other countries, we tend to prefer to cook recipes influenced by other cuisine.A．We eat them as the seasons change.B．But how much do we actually eat them?C．In conclusion, we do have our national dishes.D．Another favourite British dish is the roast dinner.E．Our diet has been greatly influenced by other countries.F．It’s also not usually something that you would cook at home.G．You’ll be served a traditional dish if you get invited for dinner at a British family’s home.三、完形填空The public library is one of the greatest inventions humankind has ever imagined and actually made happen. Libraries are a (an) 17 , quiet place where all people can hang out and read, without having to 18 anyone anything. Apart from being a place that is full of 19 to borrow, libraries are something that offers 20 and warmth. A post on Twitter celebrating the wonderfulness of libraries 21 this point perfectly.“Today a woman with developmental disabilities came into the library, and she was 22 ,” wrote a Twitter user. “She didn’t 23 her address, but her phone number was in her pocket on a piece of paper with Elmo on it. She kept saying, ‘The library is a safe place.’We called and her guardians (监护人) came right over. It seemed that they were not worried at all. Apparently this happens pretty 24 . They even stayed long enough for her to 25 some new books and Sesame Street DVDs. The library is a safe place indeed.”The post 26 others to share their own stories of libraries being safe places for them, and it’s enough to 27 even the hardest of hearts. For people who grew up in dysfunctional (功能失调的) homes, the library can be a safe heaven of calm and kindness. For people lacking financial means, the library is a space that provides free education and free entertainment, as well as a free indoor place to go. This is the reason why 28 people grouped to libraries when they have nowhere else on earth---the only place that doesn’t 29 money. We cannot understate Literal lifesavers. Libraries also fill up a lot of gaps in other social 30 and help people find their way to information about other opportunities. They open the doors to so many 31 .17.

At first people knew this club. As a result, we had only 15 members. And I 33 (laugh) at for being crazy. However, I didn’t lose heart and I insisted. Every day, we club y members broadcast weather reports and PM 2.5 levels. We then published articles and pictures of theserious 34 (pollute) of the city on the school website.

On the site Avatar Forums（论坛）, the topic “Ways to cope with the depression of the dream of Pandora being intangible（触摸不到的）” has more than 1,000 posts.In a similar forum, one user wrote, “When I woke up this morning after watching Avatar for the first time yesterday, the world seemed grey. It just seems so meaningless.”“I still don‟t really see any reason to keep doing things at all. I live in a dying world.”On another site, one fan was even more affected, admitting, “I even consider suicide, thinking that if I do it I will be rebirthed in a world similar to Pandora.”On the Avatar site Naviblue, a fan calling himself Jorba has even asked others to join him in starting a real Na‟vi tribe（部落）.Dr Stephan Quentzel, psychiatrist（精神病医生）and Medical Director in New York told CNN, “Virtual life is not real life and it never will be, but this is the pinnacle（极点）of what we can build in a virtual presentation so far.”“It has taken the best of our technology to create this virtual world and real life will never be as utopian（空想的）as it seems on screen. It makes real life seem more imperfect.”But not everyone viewing the film has been hit by the “Avatar Blues”, as a small but vocal（发嗓音的）group have claimed it contains racist（种族主义的）themes—the white hero once again saving the primitive（原始的）natives. Since the film opened three weeks ago, hundreds of blog posts, newspaper articles and YouTube videos have said things such as the film is “a fantasy about ra ce told from the point of view of white people” and that it strengthens “the white Messiah fable（寓言）.”The film‟s writer and director, James Cameron, says the real theme is about respecting others‟ differences.56. According to the passage, which of the following is TRUE?A. The audience think the theme of the film is showing respect to others‟ differences.B. The perfection created in the film makes some viewers think of committing suicide.C. Most of the viewers think the film focuses on racism.D. The film shows the humans are in harmony with nature.57. It can be inferred from the passage that _______.A. the director makes full use of hi-tech to create the virtual world in the filmB. fans voice their feelings on the InternetC. some viewers criticized racism described in the filmD. some viewers even want to create a real Na‟vi tribe58. The best title of the passage is ________.A. Avatar—A Perfect FilmB. Avatar—A Reflection of Real LifeC. Avatar’s Setting Causing Real Life ImperfectD.

To learn surf lessons, Coastlife will provide you with _______.A. a one-to-one teaching planB. free high quality equipmentC. the best beach free of dangerD. new skills of surfing on soft surfboardsCIn modern society there is a great deal of argument about competition. Some values it highly, believing that it is responsible for social progress and prosperity（繁荣）. Others say that competition is bad because it sets one person against another and it leads to unfriendly relationships between people.I have taught many children who held the belief that their self-worth relied on how well they performed at tennis and other skills. For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit（追求）of success, the development of many other human qualities is sadly forgotten.However, while some seem to be lost in the desire to succeed, others take an opposite attitude. In a culture which values only the winners and pays no attention to the ordinary players, they strongly blame competition. Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society. Teaching these young people, I often observe in them a desire to fail. They seem to seek failure by not trying to win or achieve success. By not trying, they always have an excuse, “I may have lost, but it does n‟t matter because I really did n‟t try.” What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot. Such a loss would be a measure of their worth. Clearly, this belief is the same as that of the true competitors who try to prove themselves. Both are based on the mistaken belief that one‟s self-respect relies on how well one performs in comparison with others. Both are afraid of not being valued. Only as this basic and often troublesome fear begins to dissolve（消失）can we discover a new meaning in competition.63. What does this passage mainly talk about?A. Competition helps to set up self-respect.B. Opinions about competition are different among people.C. Competition is harmful to personal quality development.D. Failures are necessary experiences in competition.64. The underlined phrase “the most vocal” in Paragraph 3 means __________.A. those who try their best to winB. those who value competition most highlyC. those who are against competition most stronglyD. those who rely on others most for success65. What is the similar belief of the true competitors and those with a desire to fail?A. One‟s worth lies in his performance compared with others.B. One‟s success in competition needs great efforts.C. One‟s achievement is determined by his particular.D. One‟s success is based on how hard he has tried.66. Which point of view may the author agree to?A. Every effort should be paid back.B. Competition should be encouraged.C. Winning should be a life-and-death matter.D. Fear of failure should be removed in competition.DBe careful! Someone may use the truth to deceive. When he tells you something that is true, but leaves out important information that should be included, he can create a false impression.For example, someone might say, “I just won a hundred dollars on the lottery（彩票）. It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”This g uy‟s a winner, right? Maybe, maybe not. We then discover that he bought two hundred tickets, and only one was a winner. He‟s really a big loser!He didn‟t say anything that was false, but he purposely left out important information. That‟s called a half-truth. Half-truths are not technically lies, but they are just as dishonest.Untrustworthy candidates in political campaigns often use this tactic. Let‟s say that during Governor Smith‟s last term, her state lost one million jobs and gained three million job s. Then she seeks（寻求）another term（任期）. One of her opponents（对手）runs an ad saying, “During Governor Smith‟s term, the st ate lost one million jobs!” That‟s true. However an honest statement would have been, “During Governor Smith‟s term, the state had a net（净）gain of two million jobs.”Advertisers will sometimes use half-truths. It‟s against the law to make false claims so they try to mislead you with the truth. An ad might boast（吹牛）, “Nine out of ten doctors recommend Yucky Pills to cure nose pimples（丘疹）.” It fails to mention that they only asked ten doctors and nine of them work for the Yucky Corporation.This kind of deception happens too often. It‟s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.67. Which statement is true according to the article?A. Whenever people tell the truth, they are really lying.B. You can‟t trust gamblers（赌徒）.C. All governors help their states.D. The truth can be used in dishonest ways.68. The underlined word “deceive” in the first sentence means ________.A. removing one‟s teeth in publicB. ignore warningsC. foolD. repair69. The author clearly wants people to ________.A. think carefully about what they read and hearB. wear mismatched socks during political campaignsC. never trust anyoneD. vote for female candidates70. An appropriate title for this passage would be ________.A. Half-truthB. Everyone LiesC. Lying With the TruthD. Nose PimplesV. 单词拼写（共20小题；每小题0.5分，满分10分）1.

There are three ways you can experience the thrill of skydiving and the only requirement is that you should be at least eighteen years old and have a weight of under 250 pounds. You also have to be free of any heart disease or severe medical conditions.Skydiving courses, in most cases, work the same way. A certified(有资格的) instructor will get you trained and he'll try to scare you and make you not jump. That‟s because the only thing he doesn't want is that a student panics while free falling. You'll then have to fill a lot of papers that you must go through if you want to jump. These documents make sure that if you get hurt the company will not be responsible. These are very scary but you‟ll have to sign them if you want to jump.When choosing the method you'll first skydive, you have to consider how much time you have and how much cash you've got. Of course, how brave you are is another factor and depending on these factors you‟ll have to choose one of three methods for your first jump. The methods are tandem（两人前后纵列）, static line and accelerated(加速) free fall. If what you want is to fly freely you have to go for accelerated free fall. Just want a nice ride, tandem might be the best choice. If you just want a quick ride you can go for static line.A good thing to take into consideration is videotaping your first jump, which costs from $ 50 to $100. You'll love looking back at how scared you were when jumping out of an airplane. If you choose to videotape your jump, another skydiver will jump before you do from the airplane and fly near you with acamera.VII. 书面表达（共1题，满分15分）假如你是班长，要组织主题班会，请你以“爱娱乐更爱学习”为主题，用英文写一篇发言稿。
