　　Nowadays, mobile phones are quite popular among students. In fact, it is very convenient to use mobile phones for self-study. Here I would like to cite English learning by using mobile phones as an example to demonstrate such a convenience.

　　现在，手机在学生中很受欢迎。事实上，用手机自学很方便。在这里，我想用手机学习英语作为一个例子来说明这样的便利。

　　First, use your mobile phone to practice your listening skills as much as you can. There are a great variety of resources about English listening over the internet and you can download some of them to listen to when you are in leisure, such as VOA, BBC, and CNN and so on. Besides, if you are fond of listening English songs, it is not a bad idea to download some of them to practice your listening skills and training your memory. In addition, English radio is also a good choice.

　　首先，用手机尽可能的练习听力技巧。在互联网上有很多各种各样的关于英语听力的资源，你可以下载一些在空闲的时候听，如VOA, BBC, and CNN等。此外，如果你喜欢听英文歌曲，下载一些来练习你的听力技能、训练你的记忆并不是一个坏主意。此外，英国广播也是一个不错的选择。

　　Second, use you mobile phone to improve your reading. Instead of spending a majority of time in chatting and playing games, you can do some reading by using your mobile phones when you are waiting bus and other leisure time because there are a lot of reading materials available over the internet, like electronic books. If you can persist in doing some reading in English everyday, you will find your reading speed becomes faster and faster and you can understand English better.

　　第二，用手机来提高阅读。当你在等公交车或者其他空闲时间的时候你可以用手机进行一些阅读，而不是花大部分时间在聊天或者玩游戏，因为在互联网上有很多阅读材料，如电子书籍。如果你能坚持每天看一些英语阅读，你会发现你的阅读速度越来越快，而且你也可以更好地理解英语。

　　In a word, the benefits of using mobile phones to learn English are various and the above are just some of them. I hope that every one of you can make full use of your mobile phones to learn something useful.

　　总之，用手机来学习英语的好处有很多，以上只是其中的一部分。我希望每个人都可以充分利用手机来学习一些有用的东西。
