Some say the convenience of a digital book beats the benefits of reading a real book, that is, a book printed on paper. Is that true? 一 二 三 四 五 六 返回目录 A famous writer once wrote, “You can find magic wherever you look. Sit back and relax. All you need is a book!” Back then, of course, he meant a book printed on paper, but today that’s not the only way to read one. People can choose to read a real book, or they can read an e-book on an e-reader device(设备) or a computer. Many people like reading e-books because they are convenient and easy to carry. 一 二 三 四 五 六 返回目录 However, a real book can never be replaced. There is nothing better than the feel of a real book, from the weight of it in your hand to the satisfaction of turning each page. It’s part of the experience of reading—just like going to a library or bookstore and turning the pages of a book freely. Scrolling(滚屏) through a device isn’t the same. And not every kind of book translates well into the digital form. Plus e-books can require expensive devices that need to be charged(充电), as well as Internet access to download books. That’s not always possible or convenient. A printed book, however, doesn’t have to be connected to be enjoyed. 一 二 三 四 五 六 返回目录 What’s more, when reading a real book, you can feel the pleasure of the mind, which will help you get information and remember it more efficiently. And it contributes to developing the communication skills and unlocking our imagination. In 2022, sales of e-books in the US totaled about $ 1 billion, while real books sales hit $ 9.1 billion. In a survey, 30% of Americans who read books chose e-books, while most still preferred real books. Besides, research shows that understanding improves when people read books in printed form, rather than in digital form. 一 二 三 四 五 六 返回目录 ( C )1. What can we know from Paragraph 3? A. People are too busy to read a real book. B. Children are into reading e-books nowa-days. C. It is enjoyable to read real books in a library. D. All the real books can be translated well into the digital form. C 一 二 三 四 五 六 返回目录 ( B )2. What’s the purpose of listing numbers in the last paragraph? A. To stress the importance of reading books. B. To show the popularity of reading real books. C. To give examples of American best-selling books. D. To compare the differences between the two reading habits. B 一 二 三 四 五 六 返回目录 ( C )3. What’s the main idea of the text? A. Reading habits are changing. B. Reading books is a good habit. C. Real books benefit us in many ways. D. Nothing compares to reading an e-book.

After winning the under-14 title(冠军) in the Guangzhou stop of the 2022 ASICS Tennis Junior Tour, an audience(观 众) member from Yunnan gave him the bamboo basket as a gift and the photos were taken. “We always carry bamboo baskets when we work in the fields. This is a typical farming tool of the Va ethnic group. I carried my rackets in this basket to honor my hometown,” Wang said after the match. 一 二 三 四 五 返回目录 Before tennis, Wang was just an ordinary boy from a village. But in 2016, he was chosen by a local club as one of the first 10 local children to learn to play professional tennis. “I was nervous in the beginning because the outside world was so different from my home,” he said, adding that tennis has helped him make more friends and get a better education. 一 二 三 四 五 返回目录 Over the past six years, Wang, along with other players at the Yunnan Wild Elephants Tennis Club, has trained hard to improve skills and physical strength.
