English is important and necessary

I am studying English not only because I will study in a European university,but also because English is indeed necessary for me.
There are really a lot of situations need English.For example,I have a foreign friend,we must have a commom language for communication.English is a good choice.I want to ask some questions at a foreign airport.English is widely used.I have a trip to another country,I should connect with the guide.English is helpful.Maybe I will have a job in a foreign company,I need to contact with my colleague.English facilitate our work.English is also used by other more satuations.
There are plenty of jobs require English in our country.Such as Taxi driver,secretary,waiter,attendant,guide and businessmen,and so on.
If I have an accident in a foreign country,the better English can I speak ,the clearer satuation I can describe.So English is helpful.
I think English is a global language.We all study English no matter where do we come from.It makes the world like a whole family ,people could have freely communication.The global language is a language which could connect people from the whole world.It could makes more understanding,more accord and more friendship.
