The word "buck" is commonly used when talking about money in the United States. A buck is one dollar. In the plural form use "bucks."

We usually don't use "buck" when asking about money. Don't say, for example, "How many bucks does it cost"? or "How many bucks do you have?" That sounds silly. When asking a question, simply ask "How much does it cost?' or "How much money do you have?"
在问关于钱的问题的时候我们一般不用buck。举些例子，不要说“How many bucks does it cost”或者“How many bucks do you have?”，这听起来很傻。在问这个问题时，简单地问“How many bucks do you have?”或者“How much money do you have?”就可以了。
The word "buck" is also used when referring to a male deer.
Brian shot a buck last weekend.
A large buck was spotted walking through the forest a few hours ago.
Note: A popular quotation in the United States is "The buck stops here." It means that responsibility for a decision rests with the decision maker. Presidents of the United States often use it when talking about themselves. This quote originated with President Harry Truman, but it can also be used by anyone who is in a position of responsibility, especially when it comes to making really big decisions.
注意：在美国有一句很流行的语录“The buck stops here.”，意思是做出一个决定所要承担的责任由做出决定的人来承担（责无旁贷）。美国的总统们谈论自己的时候经常用到这句话。这句名言来自总统哈里·杜鲁门，但是它也可为任何身居要职肩挑重担之人所用，尤其是在作重大决定的时候。
