1. 每一个句子的第一个字应该要用大写。
He is the most famous director in Hollywood right now. No doubt about it.
Give it to me. It looks like mine.
Give it to me. It looks like mine.
2.专有名词应该使用大写，例如人、物、称号、及地点的名称。
Francis Lloyd Mantel lives on Moore Street.
The class is reading The Adventures of Huckleberry Finn.
The class is reading The Adventures of Huckleberry Finn.
在第一个例子中, "Francis Lloyd Mantel" 是个人的名字，所以需要大写。"Moore Street" 是地点的名称，所以也是专有名词。第二个例子包含书的名称，所以需要用大写。
所有名字都是专有名词，所以需要用大写。其它例子:
机关、地方和地理位置的名称:
She is a new faculty member at Stanford University.
Their main office is in New Delhi, India.
Their main office is in New Delhi, India.
历史事件、日期、月份和假日的名称:
New Year's Day is a school holiday.
Classes don't meet until October.
Classes don't meet until October.
语言名称和专有形容词:
He speaks Spanish and Italian fluently.
They teach Korean dances at the academy.
They teach Korean dances at the academy.
3. 第一人称代名词"I" 一定需要使用大写，即使是在句子中间。例如:
It is I who sent you that letter.
They told me that I should call for an appointment.
4.在称呼另一个人时，我们也将father, mother, aunt, 和 uncle 等字使用大写。例如:
Aunt Bessie and Uncle Jesse just bought a country house.
Yes, Mom, I'm going after dinner.
Yes, Mom, I'm going after dinner.
可是，当这些字跟所有格代名词一起使用时，它们就不是专有名词，因此不能使用大写。例如:
My father is not at home.
Their mother is my aunt.
Their mother is my aunt.
在上面的例子中， father, mother, 和 aunt 不能使用大写，因为它们是跟所有格my 和 their 一起使用。
| 总结: | 在英文里，句子里的第一个字的第一个字母需要大写。每一个专有名词，包括名字和称号，也需要大写。第一人称代名词"I" 总是大写的。若您需要更多资讯，您可以请教您的指导教师。 |
