在美国有许多常用的字眼，往往使学习英语的中国人感到不解。在此，举一些例子供读者参考。
1. Head Start：如果这两个字开头的字母是大写，则连在一起是一个专有名词，指的是美国政府为贫穷或弱智的儿童设立的一种训练机构，帮助他们，希望他们在进小学之前能赶上教学进度。也就是：U.S. government tries to give extra － help for those underprivileged children before entering first grade. (underprivileged 比 poor 更委婉些)
例如： Many poor parents send their children to Head Start.
但是如果head start的字母是小写，那么就是普通名词了，是指比別人早着手，或领先、 有利，即：advance start or advantage
例如：In order to give his son a head start, the father decided1 to send him to a private kindergarten.（为了让他的儿子有好的开始，他决定把儿子送到私立幼儿园去。)
To know more colloquial3 expressions is a head start in learning English. (了解更多的俗语对学习英语有好处。)
2. blue blood：是指有钱人或出身富家的人 (rich or wealthy people)

Many blue blooded children attend this private school. (许多有钱人家的孩子就读这所私立学校。)
3. bed of roses：意思是称心如意的境遇；美好、理想的"安乐窝"(everything seems to be wonderful)

例如：This store sells everything from soup to nuts. (这家商店出售的货品一应俱全。)

但是如果指知识丰富的话，则不用这个词，而是通常用 from A to Z来表达，。
例如：Mr. Greenspan knows economics from A to Z. (格林斯潘先生在经济方面的知识非常丰富。)
5. real blast：blast 本来是指"一阵狂风"。但在口语中则是指欢乐，或玩得愉快，很尽兴 (have a good time; usually refers to a party or gathering4.)
