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 for the old，the sick and the busy people who cannot go to the shops by themselves.However，shopping on the smartphone also has its disadvantages. The first disadvantage is that people can't see the goods or try them on by themselves.Sometimes，the real goods may not be the same as what they have seen on the smartphone.The second disadvantage is that some shops on the Internet are not registered(登记的).They will never deliver(递送)anything to you after they get the money from you.Once you are cheated，you will find that you have nowhere to go to complain(投诉).()6.Smartphone shopping has become more and more popular in our life because______.A.we can take photos and send short messagesB.we can buy almost everything we needC.we can check emails and surf the InternetD.we can make phone calls and call a Didi Taxi()7.If you want to shop on smartphones，you should______at first.A.go to the storeB.find a suitable storeC.send emails to the shopD.download a shopping app()8.What does the underlined word“convenience”mean in Chinese?A.麻烦B.方便C.舒适D.交流()9.The number of disadvantages of shopping on smartphones is ______.A.oneB.twoC.threeD.four()10.What's the best title of this passage?A.Smartphone shopping.B.The usages of smartphone shopping.C.The advantages of smartphone shopping.D.The disadvantages of smartphone shopping.AHow winter weather influences the subway serviceWhen temperatures drop,and ice and snow fall on the tracks,know more service changes by:☆listening to your local traffic broadcasts☆visiting our website ☆signing up for email or text message warnings on our website☆following us on Twitter(NYCTSubwayScoop)☆calling our travel information line at 718-330-1234Our goal is to keep as many trains in service as possible and to keep you informed.Depending on how bad the weather is,here’s what you can expect:Service on these lines may run local on different parts of their routes:A,E,D,F,N,Q,2,3,4,5Service will change on these lines:G —Service between Court Square and 71st Street will stop for some time.7—Reduced service 11p.m.—1a.m.After 1a.m.normal late night service startsagain.S —*42nd Street train runs all night*Dyre Road trains go farther to 149th Street*Rockaway Park train goes farther to Euclid RoadExpect service on these weekday lines to end earlier than normal:B(take D or Q instead),V(take F instead),W(take N instead)Please allow for more travel time and listen for broadcasts.Thank you.2020年广东中考英语阅读理解限时训练（四）()11.People can know about subway service changes in winter through_____ ways.A.threeB.fouC.fiveD.six()12.The subway website will_____.A.send emails to some passengersB.keep all the underground trains in serviceC.follow the passengers around in the stationD.call the travel information line to know about the changes()13.What service changes there will be depends on_____.A.the weatherB.the seasonC.passengersD.the temperature()14.The service of_____lines will change if necessary.A.tenB.fourteenC.sixteenD.eighteen()15.When Line V ends earlier,passengers can take_____.A.Line7B.Line QC.Line5D.Line FBWould you like to live in a city where buildings turn the lights off for you,and self-driving cars will find the nearest parking space themselves?Although it might sound a little far from you,living in a“smart”city like this could happen sooner than you think.Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built.One such place is the city of Songdo.
