Where does the text probably come from?A. A website.B. A movie magazine.C. A science report.D. A travel guide.BFor many of us, there's nothing better than putting our heart into a good book. No matter what kind of books you read, it's good to read a book to keep you away from everyday problems. It may seem obvious(明显的) that reading is good for us. Reading can make us feel happy or make us feel sorry for characters in the book.Professor Philip Davis wrote a book called Reading for Life. He finds that when a person reads something for pleasure, the brain will begin to work from different parts and get excited.Of course, it's easy for our generation(一代人) to throw away a good book and lose ourselves in our smart phones instead. But opening up a book could be a simple way to help keep us in a healthy state of mind. It's thought that books can help us set goals(目标).If you don't like reading books, it can be hard to know where to begin. If a book list doesn't attract your attention, you can read book reviews or visit a library or a bookshop. Once you've found the right text, you'll be interested in it!59. Reading for Life is ____.①a book②a song③written by Philip Davis④about how to readA. ①③B. ①④C. ②③D. ②④60. Which of the following is WRONG according to the passage?A. Reading can help readers feel happier and get richer.B. Now we can lose ourselves in our smart phones easily.C. Reading a good book can help readers set goals.D. Reading for pleasure can let the brain get excited.61. What does the underlined word “attract” mean?A. payB. runC. pushD. draw62. What does the last paragraph want to tell us?A. We should visit a library or a bookshop at once.B. We should spend more time on smart phones.C. We should find something interesting to read at first.D. We should get a good book list first.CWhat time does your school start? Do you wish you could get up later every morning? You are not alone if your answer is “Yes”. In the US, many middle school students have the same wish.In America, many schools start before 7: 30 am. But that may change soon. A new law has been passed in California. According to the law, middle schools should not start before 8: 00 am. The government hopes school children will have a longer time in bed.Many scientific studies show that teenagers are more active in the afternoon and in the evening. Simply telling them to go to bed earlier doesn't work well. Most of them don't get enough sleep because of bad sleeping habits and early school starting time. They need more sleep in the morning. Scientists suggest middle schools should start at 8: 00 am or later. Students can get ready to learn and they won't fall asleep in class. They will pay more attention to classes. The change can help improve students' grades.While scientists are happy with the new law, many parents disagree with it. They won't be able to send their children to school before they go to work. They also fear that later school starting time will lead to later ending time. As a result, their children will have less time to take part in after-school activities.It's good news that Chinese education experts have noticed the problem. So what's your opinion? Do you expect China to pass a similar law?63. Middle schools shouldn't start before ____ according to the new law in California.64. Why don't most of the teenagers get enough sleep?A. Because they watch TV late.B. Because they have too much homework.C. Because their parents need them to do housework.D. Because their sleeping habits are bad and schools start early.65. What can we know from the text?A. Teenagers are more active in the morning.B. All the parents in California disagree with the law.C. Students in California will have more sleeping time.D. Later school starting time can lead to more after-school activities.DAncient China produced many types of beautiful art. Among them, calligraphy(书法), poetry(诗歌) and painting are the most famous. Often they would be put together in art.Calligraphy is the art of handwriting. In the old times the Chinese considered writing as an important form of art. Calligraphers(书法家) would practise for years to learn to write perfectly, and with style. Over 40,000 Chinese characters needed to be written correctly. And strokes(笔画) in a Chinese character had to be written in a certain order.Poetry is also an important form of art. Great poets were famous all over the country, and all educated people were expected to write poetry. During the Tang Dynasty poetry was so important that writing poetry was part of the examinations for a person to become a civil servant(官员) to work for the government.Chinese painting is often connected with calligraphy. It is one of the oldest artistic traditions in the world. Chinese painting is known as “national painting(国画)” or “native painting”,which is quite different from Western painting. People can drawmountains, homes, birds, trees and water on paper.66. How many Chinese characters did calligraphers need to write correctly in the oldtimes?A. Over 10,000.B. Over 20,000.C. Over 30,000.D. Over 40,000.67. What was part of the civil servant examinations during the Tang Dynasty?A. Painting.B. Calligraphy.C. Writing poetry.D. Playing music.68. Which of the following is NOT true according to the passage?A. Calligraphy, poetry and painting are famous.B. The strokes of each Chinese character can be written in any order.C. Poetry is an important form of art like calligraphy.D. Chinese painting is often connected with calligraphy.69. What is the best title for the text?A. Great Traditional Chinese ArtB.
