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 decided 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。)
