到底选哪个?要说明理由、、我觉得是不是打错了- -不是应该是eighty-story么、
2、解释一下Several millions of years ago 是什么用法.老师不是说several million of years 么、为什么million可以加s了. 详细理由.
several millions of years ago 是表示几百万年前么,和several million years ago是不是意思相同?

解答

第一题选a
有连字符时后面用单数 eighty-story’s building 就等于 eighty stories’building
又如八岁的男孩eight-year-old boy
确实是打错了……
当million前面是具体的数字时必须用单数
而当several 之类不确定的数字时用复数啊
