Every year, there is a big day for book lovers. It is World Book Day on April 23. Why not read a new book? Reading is a good habit to have in life. It shows you a different world and makes you think differently. Here are some good books Time for Kids picked out. Let's take a look!

    This Side of Wild (2015)

    Gary Paulsen, US

    If you are interested in nature (自然) and animals, this book is for you! This book tells true stories of the writer and some animals he loved. For example, a dog helped Paulsen during a bear attack (袭击), and another time a horse led him across a desert (沙漠). Surprisingly, animals can do many things. You may laugh sometimes. But these touching experiences may also make you cry.

    Diary of a Wimpy Kid: Old School (2015)

    Jeff Kinney, US

    You may have heard of this book series(系列). And this is the 10th book from it. Greg Heffley is a middle school student. He has everyday problems. Now things get even more interesting when his town decides to stop using all electronics (电子产品)! Greg faces some new problems without a mobile phone and computer. This book shows there are always a few bumps (崎岖) in the road, but you can laugh about it along the way too.

    Have you ever counted the number of digits (数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. {#blank#}1{#/blank#} Why is that?

    The 11 digits can be divided into three parts. {#blank#}2{#/blank#} The first three numbers tell you which mobile phone service provider you are using. For example, 135 is for the China Mobile Communication Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you which area the number is recorded in. And the last four digits are random (随机的).

    {#blank#}3{#/blank#} We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999.

    Eleven digits can be used to make tens of billions of mobile phone numbers, according to the Xinhua News Agency. That's enough for each person to have seven or eight phone numbers to use in China. {#blank#}4{#/blank#} Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven't contacted (联络) for a long time, you may find that its owner has changed.

    Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with. {#blank#}5{#/blank#} Countries like the United States, Australia and India use phone numbers with 10 digits. Canada's mobile phone numbers are perhaps the world's shortest: they use seven digits.

    I have ever been to many amusement parks in my country. But I have never been to a Disneyland Park. {#blank#}1{#/blank#}Disneyland is a special amusement park. It was built first in the US. There are six Disneyland Theme Parks in the world. {#blank#}2{#/blank#}China also has two Disneyland Parks. The others are in Japan and France. Shanghai Disneyland opened in 2016. I think this Disneyland will be more wonderful because of Shanghai's rapid development of modern technology. The Disneyland Parks mostly attract many children to play there. It's a great place for children to have fun. {#blank#}3{#/blank#} On the one hand, they can see the Mickey Mouse and Donald Duck with their own eyes. {#blank#}4{#/blank#}My friend Li Ling went to Shanghai a few weeks ago. She said she enjoyed herself in the Disneyland Park. {#blank#}5{#/blank#}I hope I can go there next summer vacation.
