Now we are learning English.I think there are 3 reasons that we should learn it .First of all, English is an important tool for us to conmunicate with people who are from different countries.Secondly, learning English is helpful for us to develop our technologies and science.Thirdly, we could read novels which are written by English.For example, we could read "harry potter and deathly hallows"as soon as its English edition published.
