Hi! kay, so for the beginning sentence why not say: "Today, many people all over the world study and speak English." to remove the passive voice and write more in active voice. Also in the second sentence combine it with a comma to the third.
Remove the maybe's to be more confident in your writing."First, English helps you to improve friendship and maybe include our knowledge around the world" on this perhaps say or something like <First, English helps improve international friendships and expand our knowledge with other countries .>
Nowadays, many people have a wider friendship around the world, and learning English acts as an important way to communicate with friends from other countries.
combine both of these sentences similar to this.
i dont understand this:
Every year, many teenagers go overseas to learn for themselves, to improve every important, to bring every new thing from another countries to our country.
May be say[quote=hungnguyen199The English language provides an opportunity to introduce beautiful things, places,... to internaional friends from another nation. Thus, this induces foreigners to travel to the country.
Also, since the topic is not personal, i recommend writing in third person instead of second. I think add more details and expand your ideas more because you are very vague on the job paragraph. And you have some grammer and writing mistakes, too. I hope i helped.
