1. Have you done anything that made you proud of yourself. 你做了些能使你感到为自己自豪的事情吗？
be proud of 意为"为......骄傲（自豪）"。如：
He is proud of his daughter's ability to speak four languages. 他为女儿能说四种语言而骄傲。
2. My sister returned to Greece to play for the Greek basketball team. 我姐姐返回希腊为希腊篮球队打球。
return表示"返回"时相当于come back或go back，表示"归还"时相当于give back，它本身就有back的意思，所以它不能再和back连用。如：
When you return （come back）, please call me. 你回来时，请给我打电话。
You must return the book （give the book back) to the library. 你必须把书还给图书馆。
3. I am very talented at mathematics. 我在数学方面很有天赋。
be talented at 意为"在某方面很有天赋"。如：
I found he was talented at physics. 我发现他在物理方面有天赋。
4. Every one of you is unique. 你们中每个人都很独特。
every one 表示"人人、每个人"时，它也等同于everyone。如：
Every one put on his hat. (=Everyone put on his hat. ) 每个人都带上了帽子。
every one 作代词，还可强调上面所提到的人或物，强调"全部、整体"。如：
All the students were wrong, every one of them. 所有学生都错了，没有一个例外。
