I am writing about the importance of learning English vocabulary, and I have this idea:
Just like the air, language as a medium is rarely noticed when we use it. It needs to be embedded into our daily practice to be useful. But because of its transparency, we hardly see the problem.
For clarification, the language here is transparency, or invisible, just like the air. People think that they can learn vocabulary just enough to communicate, but in fact it's not. The problem here is that it's not, but they quite confident that it is. Same as air pollution.
My native friend doesn't feel complete, but he can't think of a way to convey this message in a simple statement. Can you tell me where it's wrong, and how to fix it?
