If you found any mistakes in them, please let me know.

この書き込みは、英語学習の一貫として私 gyutaku が作った英作文です。
文法間違いやタイポなどがあれば是非教えてください。

＜Word of the day (from http://www.learnersdictionary.com/ )＞
expertise [noun]
special skill or knowledge : the skill or knowledge an expert has
⇒特別な技術や知識、エキスパートが持っている技術や知識

・His expertise on defense will help the team.
・her expertise in legal matters
・The company has no environmental expertise. [=the company does not have experience with environmental problems, matters, etc.]
・This question falls outside my area of expertise. [=the subject area I know a lot about]

＜Examples by gyutaku＞
I don't have English expertise, so I can't tell which preposition should be placed after the word usually.
⇒私は英語の専門家ではないので、その単語の後ろに普通どの前置詞がくるのかわかりません。

ググった感じでは expertise in のほうが expertise on より多いようです。
