Why Should We Learn English?

Many people are a little confused about why we should learn English and I think my answer is that English is a key to the world.

English is an international language that* which can help you to communicate with the people from all every comers of the world, and if you want to travel around the world, English is very important.

Today, many great papers, books, newspapers, and magazines are written wrote in English, and you must know the language** study English well if you want to read them.

Study more language you will get a new way to think about everything in life which they called “international thoughts”.

If you study more languages, you will reach a new way of thinking about everything in life and have a more global perspective. [I think this is what you wanted to say.]

In some ways, English is not only a tool for communication, but also a way of living. [Well said! :D]

The way of studying English itself is also very interesting, because you can learn about so many cultures during this wonderful journey** trip which could enrich your view of to the world.

That is my opinion of studying English.

These are my thoughts on studying English.

*"which" is used before a non-restrictive clause (usually with a "," before it)

**sounds more natural to me. "study English well" is grammatically fine, but awkward.

***journey vs. trip. a trip is short--maybe a week or a month. a journey is over a long period of time--years.

*Here you could also say "All corners of the world"

** I'm not 100% sure whether you mean that the more English you study the more ways you get to think about international thoughts, or that the more languages you study the more ways you get to think about international thoughts.

    Either way, the way you would phrase this would be "The more (of the English language/languages) you study, the more you will get a new way to think about international affairs*"

*A good phrase for "everything in life which they call international thoughts" is "international affairs"
