在選詞上一開始會有過於主觀或是太日常的詞彙出現，降低了論文

The adjective “well-known” seems to be too subjective and exaggerative. The modified statement is more objective and realistic, which is more suitable in academic writing.

The “academic flavor” tastes different from our daily communication and literary works. I can still remember I used the word “at the first brush” in my RA, however, this word is an informal expression. I was advised to remove the word. What I learned is that the words in the paper need to be formal and rigorous to give the paper an academic flavor.
