My english learning outcomes

My English teacher said to me as follow.

You seem you have already known about the basic of English grammar and how to make English sentences.
Learning idioms and the natural expressions will help your English to be improved.

When I started writing an English diary, the grammar was messy.
My English seems to be improving.

英語の先生が、こんな事を言ってくれた。
「英語の基本的な文法、文の組み立てはもうマスターしてると思うので、あとはイディオムやもっとナチュラルな英語の言い回しを覚えて、さらにレベルアップですね！」

日記書き始めた頃は、文の組み立てすらメチャクチャだったんで、ある程度はレベルアップはしているみたいだぞ！
