Translation / English

I know it's too much a demand, but I really want to master a much wider range of vocabulary.
I'm aware that my vocabulary level is so elementary that my sentences become a bit dull. That's why I would like to improve my English skill through learning various kinds of words.

Translation / English

I'm afraid I'm asking too much of you. I want to learn more different English words. Vocabularies I use are too simple, and I think I can't write good sentences. So, I think I try to learn various words to improve my English skill.
