The drama also expresses the longing for brightness indicated by the name and order of its four acts——dawn, dusk, midnight and sunrise.Rickshaw BoyPlaywright: Mei QianThe drama Rickshaw ō Boy is adapted from the novel of Lao She, a Chinese literary giant. It tells the sad story of`Xiangzi, a rickshaw boy in Beijing in the 1920s who dreams of running his’ own firm. However, after a series of misfortunes, Xiangzi is no longer an honest and optimistic young country boy.The TeahousePlaywright: Lao SheConsisting of three acts, the play tells stories taking place in the Beijing Yutai Teahouse and the fate of Wang Lifa, the owner of the teahouse. It mirrors the great social changes in China from 1898 to the 1940s. The Teahouse is also the first Chinese drama production to be performed overseas.【小题1】Which story takes place within a day’s time?【小题2】What may the title of Sunrise imply?【小题3】What do Rickshaw Boy and The Teahouse have in common?2、Like most of his classmates, Zhang Yixuan is facing academic pressure as he is preparing to attend the national college entrance examination, or gaokao, next year. However, compared with playing smartphones and games, Zhang Yixuan prefers spending his summer vacation walking in wild nature, meeting little creatures like crabs. His bedroom is packed with dozens of “living treasures” that he has collected from the outdoors, including insects, fish, and crabs.It is the microscope that his father bought hi m that makes the bedroom look more like a mini-biology lab than anything else and it’s a place where Zhang can devote himself to identifying or observing crabs day and night. With the help of the microscope, Zhang buries. Himself in studying the natural world. Sometimes he spends hours simply examining the leg of a crab. It was his deep interest in nature that led Zhang into a new world of discovery.Last year, a group of crabs caught Zhang’s attention since they looked unusual compared with the commonly seen ones in Rongxian county, where he lives. He decided to take seven of them home. After much observation and lo tsof researches by reading related articles and documents, Zhang speculatedthat it must be a new species. And it proved to be true by experts.The hardworking and gifted teenager is very grateful to his parents for their understanding and support. His father Zhang Lefei, who was born in a rural area, loved catching fish and crabs himself at an early age. So he and his wife would take their son out into nature to explore as much as possible and would allow him to observe crabs quietly without any disturbs.They say interest is the best teacher. And so are parents, it seems.【小题1】What does paragraph 1 mainly tell us about Zhang Yixuan?【小题2】Where does Zhang Yixuan carry out his research?【小题3】What does the underlined word “speculated” in paragraph 3 probably mean?【小题4】What is the author’s purpose of mentioning Zhang’s parents?3、Disability is an unavoidable outcome of living. There is no perfect body or mind. And there is no normal body or mind. In other words, no one is perfectly “able”. Everyone faces limitations, and some might face more severe limitations at different times in life through age, illness, or other unexpected occurrences. Having a disability, however, should not stop anyone from learning. As a result of several recent international movements, schools in nations around the world now provide inclusive education, which means that students with disabilities have access to the common curriculum(课程) in the general education classroom.English language instructors need to provide equal instruction to all learners in inclusive settings. Online learning has made it possible for many students with different kinds of disabilities to access classes and learning materials that were once out of reach or difficult to obtain. However, whenever teachers do not adopt necessary measures to accommodate as widely as possible in digital ces, they sometimes unknowingly create barriers for students with disabilities. It is our responsibility as educators to be aware of that.While we are acquiring or updating skills for teaching online, we should give equal attention to understanding how to accommodate students with disabilities in a digital learning environment. When we do not make our classes accommodating to all students, some students are left behind through no fault of their own. Whenever we work to create inclusive learning environments, we provide support for all students, with or without disabilities.The online learning environment provides multiple ways to make learning interesting through media. and technology tools. It is important not to use technology just for the sake of attracting attention, however, but to use it because it has a learning purpose that you are clear about. For instance, don’t show a video just because it’s fun, but because it helps achieve a learning goal.【小题1】What can be inferred from the first paragraph?【小题2】What makes learning materials more accessible to the disabled?【小题3】What can we know about the author ?【小题4】What may be the proper reason for playing a song in class?4、Brynn Schulte nearly died two times when she was a baby. At one point she needed emergency surgery for bleeding in her brain. No one knew what was wrong. Then, a test that looked at her full genetic details found a rare bleeding disorder. Catching the disorder early saved her life. “You have this hopeless feeling when you don’t really know what’s going on,” said her father, Mike Schulte. He noted that the test made a difference in finding the cause and “getting her the right care that she needed almost immediately”.Brynn, now 4, got the genetic testing as part of a clinical trial, the results of which were published recently in The Journal of the American Medical Association. Testing all of the details of a person’s genes is called “whole genome” testing. Whole genome tests are much better than narrowly targeted tests when it comes to finding genetic differences, called abnormalities, which can cause disease. The study found 49 percent of these abnormalities, compared to 27 percent with more commonly used tests targeting only some genetic diseases.Whole genome tests could solve the problem of doing several narrowly targeted tests on babies, which still might not find the disorder. Experts warn there are some problems because labs vary in how they understand results. Also, whole genome tests are more expensive and less likely to be covered by insurance.But researchers hope that whole genome tests will at some point be used for millions of hospitalized babies with rare and difficult conditions. The US National Human Genome Research Institute hasfound that around 350 million people around the world live with rare disorders. And it found that about 80 percent of the more than 7,000 conditions are genetic.【小题1】How did Mike Schulte feel about the test?【小题2】In finding genetic diseases, .【小题3】What disadvantage do whole genome tests have?【小题4】Where is the text most likely found?5、End of Heat, the 14th solar term of the year, implies that most parts in China are getting rid of the hot summer and entering autumn. 【小题1】Enjoying cloudsWhen the End of Heat comes, summer heat is gone. Clouds in the sky scatter around forming different shapes. There is a saying that goes, “Enjoying the clouds of various forms in July and August (lunar month).”Autumn wearinessThere is a saying that goes, “People tend to feel sleepy in spring, doze in summer and feel tired in autumn.” As the weather becomes cool during End of Heat, many people will feel tired and weary, which is called “ autumn weariness”. 【小题2】 Get enough sleep, do more exercises and keep plants indoor to help.Eating DuckDuck has a sweet flavor and according to traditional Chinese medicine it has a “cool” nature.【小题3】 There are many recipes for cooking duck such as roast duck, cooked duck with lemon, smoked duck with walnut dressing and sautéed duck with ginger shoots. The tradition of eating duck during the End of Heat period is still popular in China.The Fishing Season Festival【小题4】 . During this . period, the Fishing Season Festival is held in regions along the coastline of the East China Sea in Zhejiang Province. The festival is held on the day when the fishing ban ends and fishermen can start fishing again. Due to high temperatures in the sea, stocks of fish remain and become mature. 【小题5】6、They walk down the catwalk, slim figures displaying the latest designs with cool, confident looks on their faces to match. The model quartet (四人组), a group on online platforms like short-video site Douyin, is made up of four female retired from different careers. At an average age of 71, they more than 100 million views online and over 3million with their online fashion videos alone.

But he talked with Mr. Dolman, his science teacher, who knew that there was something different about him. Philo told Mr. Dolman that he wanted to learn all about science. He began to study science with the first-year class. After a few days he appeared in the fourth-year class also. Philo studied very hard. Soon he knew everything that the fourth-year class was learning. Then he read all the science books in the school library.One day after school Mr. Dolman found Philo in the classroom working at the blackboard. Philo had covered the blackboard with drawings.“What are you doing?" asked Mr. Dolman, with interest. " What are these drawings about?”“I want to invent things, " Philo answered, " and these are the drawings of my first invention. "“What is your invention?" Mr. Dolman asked.“I have an idea for television -for a way of sending pictures through the air, "the boy answered. And then he said happily to his teacher, " Please let me tell you about it, because you‟re the only person who can understand what I have done. "In 1922, radios were very few. The United States had fewer than 30 radio stations. But in 1922 a boy of 16 showed his teacher drawings for a television.86 . What kind of boy was Philo'?A. He was large and shy.B. He was shy but loved science.C. He was a boy of many words.D. He didn‟t talk to anyone.87. Mr. Dolman was a ______ teacher.A. GermanB. musicC. scienceD. history88 . What was the boy interested in?A. Science.B. Literature.C. Sports.D. Art.89 . One day Philo covered the blackboard with ____A. drawings of a buildingB. drawings of a radioC. drawings of a machineD. drawings of a television90. What might be the title of the passage?A. A l6—Year-Old BoyB. A Boy and His TeacherC. A Shy Boy, a Great InventorD. A Strange BoyPassage 3Some people have good memories (记忆), and can learn quite long poems (詩)by heart. Others can only remember things when they have said them again and again. Charles Dickens, a famous English writer, said that he could walk down any long street in London and tell you the names of every shop he had passed. Many of the great men of the world have wonderful memories.A good memory is a great help in learning a language. Everybody learns his own language by remembering what he hears when he is a small child. Some children, whose parents speak different languages, seem to learn two languages almost as easily as one. In school it is not easy to learn a foreign language because students have so little time for it, and they are busy with other lessons, too.A man‟s mind is just like a camera, bu t it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way, there is much work to be done before we can keep a picture for ever (永远) in our minds.91. Some people can only remember things______.A. by repeating themB. by keeping a pictureC. by learning a foreign languageD. by hearing, smelling and tasting92 . Charles Dickens _______A. liked walking in London streetsB. exercised his memory by remembering the names of shopsC. had a very good memoryD. could speak two languages easily93. A good memory helps you ____A. hear, smell and tasteB. keep a picture for everC. learn a foreign language wellD. tell others the name of every shop in London94 Remembering something is just like ___A. learning a poemB. taking photosC. learning EnglishD. feeling something95 It is not easy to learn a foreign language well in school because _____.A. students have so little time for itB. students are busy with other lessonsC. students have no foreign teachersD. Both A and BPassage 4The world is not only hungry, but it is also thirsty for water. This may seem strange to you, for nearly 70 perce nt of the ear1h‟s surface (表面) is covered with wa- ter. But about 97 percent of that huge amount of water is sea water. Man can only drink and use the other three percent — the fresh water that comes from rivers, lakes, andunderground. And we cannot even use all of it, because some of it is in the form of ice and glacier (冰川). Even worse, some of it has been polluted.However, this small amount of fresh water, which is sometimes replaced ( 替代)by rainfall, is still enough for us. But our need for water is increasing rapidly almostday by day. Only by taking steps now can we deal with a serious water shortage (不足) in the future.One of the first steps we should take is to develop ways of reusing water. Today,in most large cities, water is used only once and sent into an underground system, from which it goes to the sea or runs into underground storage tanks ( 蓄水池). But it is necessary to treat used water with chemicals (化学品) so that it can be used again. Another way is to make use of sea water by removing the salt. This way of water treatment is already in use in many parts of the world.96. " The world is thirsty for water" means that _____A. there is not enough fresh water in the worldB. the people of the world are thirstyC. people drink a lot of waterD. people drink more water than before97. Which of the following is NOT TRUE?A. There is much more sea water than fresh water.B. Fresh water comes from rivers, lakes and underground.C. Ninety-seven percent of the earth‟s surface is covered with sea water.D. Some of the fresh water has been polluted.98. People will need in the future.A. some sea waterB. less waterC. the same amount of waterD. more and more water99 "Taking steps" means _____A. go aheadB. move forwardC. step forwardD. take measures (采取措施)100 . People treat used water in order to ______A. use the chemicalsB. reuse itC. store it in underground tanksD. send it to an underground system。
