Haiyan is 7 years old. Her parents gave her an iPad as a gift for her birthday. A month later，her eyesight（视力）dropped to 300 degrees. This is serious for such a young child.

    Many children in China are facing the same problem: iPad using is bringing problems to their eyesight. The problem is so common that newspapers even call the iPad the "No. 1 killer of children's eyesight!"

    "There are about 30 shortsighted children coming every day, "said Hu Dali, an eye doctor at Guiyang Aier Eye Hospital. "Half of those children have poor eyesight because they have played with phones and iPads for too long. "

    Doctors and scientists say children's vision（视觉）is not yet fully developed and their eyes get tired more easily. The screen of an iPad uses very bright（明亮的）LED backlight. If children look at an iPad screen for a long time, their eyes do not have time to rest. This will make their eyesight worse over time.

    Doctors advise that users should hold their iPads between 40-60 centimeters（厘米）away from them. The brightness of the screen should be comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.

Reading for pleasure (消遣) is the easiest way to become a better reader in English. It is also the most important way.

Some students say they don't want to read for pleasure. They say they want to use their time to learn the rules of the language and new words. They say that pleasure reading is too busy.

Many experts (专家) say that pleasure reading is very important for learning English. Dr. Stephen Krashen, a famous expert on learning languages, says that pleasure reading helps you learn many important things about English. Students learn more grammar and more words when they read for pleasure. They also learn more about good writing.

Dr. Krashen tells us that pleasure reading helps each student in a different way. Each student needs to learn something different. Pleasure reading makes it possible for each student to learn what he or she needs.

Reading for pleasure is not the same as studying. When you read for pleasure, you choose your own books, and you don't have to remember everything. There are no tests on your pleasure reading books. Pleasure reading will help you：

•learn how English speakers use English

•read faster in English 

•find examples of good writing in English

•learn new words 

•learn about the culture of English speakers
