ago表示一段时间。
例:一分钟前a minute ago
半小时前half an hour ago
两天前two days ago
一星期前a week ago
五年前five years ago
因为a minute,half an hour,two days,a week,fiveyears等都表示一段时间,所以用ago。以及ten dayslater等皆如此。
before可接完成时,ago过去级有限
这时的before是连词(也可做介词)
例:We had scarcely left our school before itbegan to rain.
我们刚离开学校,天就下雨了。(完成时)

我来这儿以前就已学了四个月法语了。(before接完成时)

上山,向北方等都属于up。而相反的下乡,向南,落榜等都属于down。"大军南下,北上抗日"大概由此而来。
