Input is Key
If you want to learn a language, you need to get used to it.
I think the Japanese expression "narau yori narero" is good advice.
*expression:思想・意見・考え
Studying grammar may be helpful at times but, in Japan, grammar is often overemphasized while students do not have sufficient opportunities to get used to English.
*overemphasize:〜を過度に強調する
*sufficient:十分な・足りる
*opportunity:機会・好機
Textbooks are too thin and students don't get to hear natural English often enough.
*natural:自然の・天然の・無理のない・気取らない
One very important way to get used English is to find "input" that one is interested in and can enjoy.
By input, I mean either texts that you can read or spoken language that you can listen to.
This class is called Gaisho Kodoku so it is natural that we should read in this class.
I think, though, that our study will be more effective if we can find materials that we can both read and listen to.
