hundred、thousand、million、billion
当hundred、thousand、million、billion前面有具体数量词的时候，它们是数量词，没有复数变化，如: a thousand, three thousand, eight million等；当它们前面没有具体的数量词时，则它们是名词，总以复数形式出现，表示数量之多，但不确定，一定要与介词of构成短语之后才能修饰名词, 如：hundreds of boy数百男孩，thousands of birds数千只鸟，millions of people数百万人，If I had billions and billions of dollars（数十亿美元）, I will buy you everything you want... but that's impossible... haha.
