English is a subject,a language, although it's a bit difficult to learn , many people study it. The people here include you and I. Why do they study English? The answer is different. In my opinion, I study English because it's useful and it's also the key to the sucess. A lot of chances will come to you if you're good at English. I study English with a reason : I want to travel around the world without any translator. To sum up, English is very necessary and useful for you to use in the life.
