★problem in using English

First, I find the biggest problem for me is vocabulary when I read, write and speak English. I think I know most of frequently used grammatical rules because the Japanese English education system is focusing on it. And, vocabulary is more difficult than grammar for me to memorize. I think this is similar to that people tend to have more difficulty in remembering actors’ names than the story of movies.

Secondly, I find the second biggest problem is how to use proposition. There are so many propositions in English. And, there is no simple rule which tells me how to use propositions as far as I know. I will improve my English ability especially in these two themes.
