是以个固定搭配
millions of指的数以万计的,在数量上很多.
其他的量词也可以的,例如:hundreds of , thousands of .
Example: hundreds of thousands of visitors come to visit this famous scenic spot every year.dollars of money 呢?＿相当于量词，如pieces。那麽把原句改为:it can't not pay the thousands of millions ofmoney it owes. or it can't not pay the thousands of millions of dollars it owes. 可以不?语法上没有错，但上面的那种表述更加native。 如果帮到你的话，请选为满意答案吧！
