In my opinion, learning english is very important to everyone. Because english is an international language. Nowaday, many global companies are hiring a lot of employees who can speak english very well with an extremely high salary and good professional skills. If you learn english, you can have many social relationships, many good opportunities you will have a comfortable life . If not, you will loose them. You will meet many difficulties.
Besides, i assume that we should try to ensure the survival of local languages. Because the local language is a seperated, different identity of a nation. If we loose it, the society develops very slowly, we won’t have many maverlous memories.
After all, i am definitely sure that english and local languages are very important but english need to have to learn and local languages need to keep on.
