信中有提到one on one，此時有點疑惑，不是應該寫one by one嗎??
於是，我查了字典且上網查資料
One by one：一個接著一個，逐一地
- He shot arrows one by one, but each missed. (他射了一箭又一箭，但都未射中。)
- All the applicants were interviewed one by one. (所有的申請者一個接著一個參加面試。)
- For some years after his retirement he kept up with a number of his old workmates, but as time went by he dropped them one by one. (退休後的幾年裏，他還同很多老同事保持著聯系，但隨著時間的推移，他們的聯系就一個一個地中斷了。)
One on one：一對一
- one to one, one for one
- Some students prefer to be tutored one on one. (有的學生喜歡老師單獨輔導)
