Time flies, and I have grown up a lot. Comparing with the past, I have changed in appearance, personality, hobbies, and lifestyle. The most important change is my personality. I used to be very shy and introverted. I remember when I was in Grade Seven, I was afraid to speak in front of the class. One day, our teacher asked me to give a presentation. I was so nervous that I almost cried. However, with the encouragement of my teacher and classmates, I managed to finish it. Since then, I started to gain confidence. I joined the school’s debate team and participated in various activities. Gradually, I became more outgoing and confident. Now, I am not afraid to express myself in public. This change has made my life more colorful and meaningful.

We should read books as much as possible. Here are four books for you. Be Amazing Cyclist Sir Chris Hoy tells his own wonderful story of becoming a six-time Olympic Champion (冠军) in this book. There are lots of useful ways to help you build confidence (自信) and take failures with a peaceful mind. Dare to Be You This book tells people that there’s no such thing as normal (标准). It calls on difference and diversity (多样性). The book encourages you to follow your own way and love what makes you stand out (脱颖而出) from the people. The Book of Me This book will take you on a journey to search for your imagination, mind and much more. Through writing, drawing and other activities, it is written to help you learn more about who you really are and who you might become. Be Your Own Superhero Are you sad? Are you not confident? This fun book will take you experience some activities, which will help you feel in control of your life, happy and confident, and will leave you feeling like a superhero. Each book is 30 yuan. If you buy two of them, you can get 20% discount (折扣). And if you buy four books, you can get 40% discount. 21.How does the writer begin the passage? A. By asking a question. B. By telling a story. C. By expressing an idea. 22.What can we know from the passage? A. We can learn to control ourselves to get happiness in Be Amazing. B. We can learn to build confidence and accept failure in Dare to Be You. C. We can learn to know who we really are in The Book of Me. 23. If you want to buy two books of the four, how much will you pay? A. 30 yuan. B. 48 yuan. C. 60 yuan. 24.In which part of a magazine can we read the passage? A. Culture. B. Travel. C. Health. B When you were a little child, you depended on your parents a lot. They used to make decisions about everything for you because you weren’t old enough to take care of yourself and make careful decisions. For example, they choose the clothes you wear, the food you should have and the after-school classes you should take. Finally, however, you grow up and become a teenager. You begin to have your own ideas and opinions about life. You want to make your own decisions. As you change and grow into this new person who makes your own decisions, your parents may have a difficult time getting used to that. They only see you as a child. In most families, this can cause lots of arguments between teenagers and parents. You want to cover your walls with posters, but your parents don’t understand why you don’t like your wallpaper anymore. Then you feel your parents don’t respect you and don’t allow you to do what you like, and your parents get angry because they disagree with your decisions. And some other things—like the kind of friends you have—can cause even bigger arguments, because your parents will always be ready to protect you and keep you safe, no matter how old you are. However, the good news is that there will be fewer arguments as your parents are aware that you have grown up and should have your own ideas. Before you get on very well with each other again, communication between you and your parents is very important. 25.The writer talks about ________ in the first paragraph. A. the decisions you may make B. the changes you may make C. the happy time you may have 26. Which of the following is TRUE according to the passage? A. Parents always think that teenagers don’t respect them. B. Parents don’t think that teenagers need protection when they grow older. C. The kind of friends you have may cause bigger arguments. 27. What do the underlined words “are aware” in the last paragraph mean? A. Warn. B. Request. C. Realize. 28. The writer suggests that teenagers should ________. A. talk with their parents often B. agree with their parents’ ideas C. learn to protect their parents C China has a long history of using incense (熏香). Chinese people love incense and know how to make it. Different kinds of Chinese herbal (药草的) medicines were chosen by ancient Chinese to make incense that could clean the air and keep the mind clear. As early as the pre-Qin period, people burnt incense to wish for a better life. Later, it was found that incense could be used to keep away insects. Gradually, the ancient people began to use incense to eliminate (清除) foul gas (臭气) and avoid illness. In ancient times, incense would also be used to tell time. For example, in the calculation (计算) of exam time people would light a stick of incense. When it burned out, the exam was over. This is what Chinese people call “the duration of a stick of incense”. What’s more, incense in the shape of balls would be put in a special bag. Different smells of incense can work differently. When it is heated, the cloth covering this bag also smells fantastic. It’s said that incense can also be used to improve people’s health. When I feel stressed, the pleasant smell can make me relaxed. I feel that I can taste the classical culture from the incense. Ancient Chinese people believed that beautiful things that smell good could help people relax. Chinese people still like incense now. It brings out the intelligence of the mind and silently harmonizes (协调) the mind and the body. 29.Why did people during the pre-Qin period burn incense? A. To clean the air. B. To keep away insects. C. To wish for a better life. 30. Which of the following can best explain the meaning of the underlined sentence in the text? A. The heat of a stick of incense to produce. B. The time of a stick of incense to burn out. C. The smoke of a stick of incense to spread. 31. How does the writer feel about the pleasant smell of incense? A. Excited. B. Relaxed. C. Stressed. 32. Which of the following best shows the structure (结构) of the passage? (P=Paragraph) D Zigong, in Sichuan Province is home to Chinese lanterns. Zigong lantern is known as the best lantern in the world. The Zigong Lantern Festival dates back to the Tang Dynasty. The festival has rapidly developed with traditional culture and modern technologies. In 2008, the Zigong Lantern Festival was listed as a national intangible cultural heritage(国家级非物质文化遗产), becoming a shining name card for Chinese culture to go out into the world. “Making a huge lantern for exhibition requires 17 steps,” said Wan Songtao, an inheritor (传承人) of Zigong lantern-making. “Each step is finished by a team instead of only one maker.” Wan added. The sundial (日晷), a kind of lantern, made by Wan’s team, for example, took about 80 makers over 50 days to complete the whole process. Unlike the lanterns in other places, Zigong lanterns use modern technologies such as AI, mechanical engineering (机械工程), and holography (全息摄影术). They are perfect combinations (结合) of lights, sounds and movements. What’s more, the theme of the lantern can be showed in different ways. “Anything that can be designed on a lantern can make a wonderful show, and everyone is encouraged to turn their ideas into real works,” said Zhang Fanglai, a leading researcher at the Colorful Lantern Museum of China. And the rich themes of Zigong lanterns show the spirit of creativity and warmth from the bottom of the local people’s heart. The government encourages local people to learn lantern-making widely. Without doubt, at the heart of the Zigong Lantern Festival’s success is the local tradition of pulling together. Zigong lanterns are getting more and more popular. Driven by the collective efforts of the whole city, they have reached over 80 countries. It’s believed that Zigong lanterns will reach every corner of the world in the future. 33. ___________could probably enjoy Zigong lanterns. A. Cao Cao B. Li Bai C. Tao Yuanming 34. What can we infer(推断) from Paragraph 2? ①Holography is a kind of traditional technology. ②It’s hard for makers to complete a huge lantern for exhibition. ③Zigong lanterns are different from the lanterns in other places. ④The workers of Zigong lantern work together in a team. A.①②③ B. ①③④ C. ②③④ 35. According to the passage, what’s Paragraph 3 mainly about? A. The rich themes of Zigong lanterns. B. The long history of Zigong lanterns. C. The excellent inheritors of Zigong lanterns. 36. What’s the best title (标题) for the passage? A. People in Zigong. B. Zigong lanterns. C. The makers of Zigong lanterns. （二）阅读下面短文，根据短文内容，从下列选项中选出能填入文中空白处的最佳选项。选项中有一项为多余选项。 E In fact, a lot of languages can still be learned best in more relaxing situations where students are having fun. Here are some suggestions. ★ 37 If you live in an area filled with English speakers, get students out of the classroom. Put them among other English speakers. Students may not speak to strangers, but they’ll hear conversations and may begin to understand how the words learned in the classroom are actually used in everyday life. ★Let their guard (警惕) down. One difficult thing for learners is that they don’t have confidence.Fun activities, especially those outside of the classroom, give students a chance to feel relaxed. 38 It may take a bit of time in the beginning, but once students get into it, they’ll start to get confidence. ★Make use of English media. Most recorded language instruction (指导) is pretty boring. 39 They will hear common expressions and more everyday conversations in the movie. If they’re not sure about anything they hear, you can turn it into a new lesson in the classroom. ★ Hear or use English in situations. Casual conversations give learners the chance to hear or use English in situations. In different situations, they can talk about their favorite films, super stars and any successful or famous person freely.

But it is always difficult 51 (find) enough time to study every subject you need. So a good plan helps you to make sure of your 52 (succeed) in study. Then, how can we make a study plan? Well, begin with listing all the subjects you need to study and make sure 53 you need to do for each subject. Next, decide how much time you should spend 54 different subjects. Now, it is a good idea to study at the same time every day. In this way, you actually have a plan you can remember 55 (easy). While arranging (安排) time for each subject, you also need to make sure that you still have time for family, friends and rest. This is because you won’t be able to succeed in your studies unless you balance your personal life and your study. Once the plan 56 (make), the next thing you need to do is to follow it. One of the 57 (big) challenges in following your study plan is that you will be tempted (诱惑) to avoid it and do something relaxing or fun instead. Luckily, you can fight this temptation by taking breaks. But be sure not to take extra breaks or too long breaks because it can affect your plan. So at the start of your break, set 58 alarm clock to remind you when your break is over. Also, you need to use your break wisely. For example, go for a short walk, eat a small snack, or listen to some music. To avoid 59 (forget) to follow your plan, try to get into the habit of looking at your calendar every day. Sometimes our plans are hard to follow 60 some important people in our lives distract (使分心) us from our goals. In order to avoid this, tell people around you about your plan. Put up a copy of your study guide at home so you and your family can see it, and email a copy to your friends so they know when you have spare time. 答案：51. ________ 　52. ________ 53. ________ 54. ________ 55. ________ 56. ________ 　57. ________ 58. ________ 59. ________ 60. ________ 四、阅读表达（共5小题；每小题2分，计10分） 阅读下面短文，完成短文后的问题。 Since the age of 5, Laura Lee has had a strange habit—she collects cardboard toilet-paper rolls (厕所卷纸筒). She didn’t know this habit would become a recycling movement one day . In 2018, Lee set up a goal to collect 1,000 kg of these rolls. She was then a 16-year-old student at Nanyang Girls’ High School in Singapore. As of February 2021, she collected 860 kg. She received an Ecofriend Award from the Singapore government. Why did she choose toilet rolls? “They are convenient to collect and also one of the purest forms of waste to recycle because they are made of only one material,” Lee told Singapore Today. “It’s more difficult to recycle pens because they are made up of too many different materials like rubber casings (橡胶外壳), metals and plastics, which require more resources to separate (分离).” Lee went into a partnership with the waste management firm Veolia. The firm gave her money for every kilogram of toilet rolls. She organized “toilet roll challenges” in her school and worked with cleaners to collect used toilet rolls. She gave speeches about what she was doing at local schools. She also raises awareness (意识) about different social groups through her Instagram Live series, “On A Roll”. One big challenge Lee faces is others doubting her because of her young age. “I always have to use my actions to prove that I’m passionate (有热情的) and know about this,” she said. She will donate the money collected to a social cause focused on community health. 61.
