1. Have you done anything that made you proud of yourself. 你做了些能使你感到為自己自豪的事情嗎？
be proud of 意為"為......驕傲（自豪）"。如：
He is proud of his daughter's ability to speak four languages. 他為女兒能說四種語言而驕傲。
2. My sister returned to Greece to play for the Greek basketball team. 我姐姐返回希臘為希臘籃球隊打球。
return表示"返回"時相當于come back或go back，表示"歸還"時相當于give back，它本身就有back的意思，所以它不能再和back連用。如：
When you return （come back）, please call me. 你回來時，請給我打電話。
You must return the book （give the book back) to the library. 你必須把書還給圖書館。
3. I am very talented at mathematics. 我在數學方面很有天賦。
be talented at 意為"在某方面很有天賦"。如：
I found he was talented at physics. 我發現他在物理方面有天賦。
4. Every one of you is unique. 你們中每個人都很獨特。
every one 表示"人人、每個人"時，它也等同于everyone。如：
Every one put on his hat. (=Everyone put on his hat. ) 每個人都帶上了帽子。
every one 作代詞，還可強調上面所提到的人或物，強調"全部、整體"。如：
All the students were wrong, every one of them. 所有學生都錯了，沒有一個例外。
