With the explosion of digital media in recent years, a growing number of students are spending their time in front of the small screen---whether it’s a Smartphone or tablet. In just two years, the number of US children using digital media has doubled to 72 percent, according to a survey by Common Sense Media.
On average, students spend about two hours a day in front of the screen. Watching TV makes up half of this time. But gradually, the time children spend watching TV is decreasing, with more and more time being given to digital media. Some of the common things kids do with digital media are playing games, watching videos and sending messages to friends.
The digital world can be used very effectively. In the survey, 74 percent of teachers said that digital media would improve students’ learning. As students can quickly get hold of information they need.
However, without guidance from teachers or parents, digital media may have bad influence on students’ attention span and communication skills. So it’s always best to use your smartphone and tablet carefully.
When using digital media, you need to find a balance. Just like study, too much can lead to information overload, and give you a headache. Also, make sure your smartphone or tablet doesn’t take priority over more important tasks. Give your eyes a rest, and remember: offline is just as fun as online.

"二、阅读理解:阅读下面的短文,根据文章内容进行判断,正确为“T”,错误为“F”。
WILL E-READERS REPLACE THE CONVENTIONAL PAPER BOOK?
Kindles, Nooks and other e-readers are threatening the future of printed books. But reading itself may get a boost from the devices. For example, a study found that the kids felt better about reading after a course in which they used Amazon Kindles. The research is in the _International Journal of Applied Science and Technology._
For two months, 199 middle-school students in a reading improvement class in Texas had 15 to 25 minutes every day when they were free to read on the Kindle. In general, the students felt the device improved their reading ability. And they tended to enjoy using an e-reader.
They noted the ease of carrying multiple books in one device, and the feeling that reading was suddenly a high-tech 21st-century activity rather than a boring waste of time. And some low-level readers who might otherwise be embarrassed to be seen with a simple book liked keeping their peers in the dark about what title they were reading. In the old days, one had to use a fake book-cover to achieve that level of secrecy.
1. Amazon Kindles is a kind of e-books. {T; F}
2. The research done in the _International Journal of Applied Science and Technology_ has lasted for two years. {T; F}
3. The students felt e-books could not improve their reading ability. {T; F}
4. Many students tended to enjoy using an e-reader. {T; F}
5. Some low-level readers used to use fake book-covers to keep their peers in the dark. {T; F}"
