I am opposed to the idea of learning languages other than English.//
Since it is the most widely used language globally, we can communicate in English with people from many different corners of the world.//
In order for us to work in the global community, English is indispensable, as it is used as a tool for communication in various fields.//
Moreover, these days, English is becoming a vital component in educational and occupational activities in Japan.//
Therefore, we should concentrate our efforts on the acquisition of English.//
For these reasons, I disagree with the idea that we should learn languages other than English.//
