Why students learn English?

The students in China start to learn English when they are in primary school. In many provinces, English are taught as second language. Some people may ask why we need to learn English, what we do that for? Well, in my humble opinion, I think we need English for various reasons. 
中國的學生從小學開始就學英語了。在許多省份，英語作為第二語言教授。一些人問我們為何要學英語，學英語有什么用。在我看來，我認為我們學習英語有不同的原因。
First of all, English is indispensable if we want to enter the university. English teaching in some schools are quite important. Some teachers even use English instead of Chinese to teach their students. Secondly, most of students will need English to read English books or novels. While a few of them will go abroad to study, then English will become a tool to communicate with foreigners. Last but not least, as this world gets smaller, English has become more useful than ever. There are a lot of songs singing in English, if we know how to speak English, we can know about the the lyrics all about. What’s more, sometimes we need to say English to communicate with others. Through English, we know about what happen all around the world. 
首先，英語在大學入學考試中必不可少。英語教育在一些學校中也有其重要。一些老師甚至用英文而不是中文來給學生上課。其次，大多數學生在讀英文書籍和小說時要用到英語。而一些學生則要到國外去學習，英語則用作于他人溝通的工具。最后一點，這個世界變得更小了，英語比任何時候都有用。有很多歌曲是用英文唱的，如果我們會說英語，就知道這首歌唱得是什么了。有時候我們還需要用英語與他人溝通。通過英語，我們了解到世界各地發生了什么。
To sum up, learning English is very useful as well as important in our life. To master another language is better than learning nothing at all. 
總的來說，學習英語不僅僅有用，也非常重要。掌握一門語言比什么都不會的好。
