ago 和before:
ago 不能单独使用,应与three days (months , weeks)等连用, 而且和动词的过去时连用。如:I met my neighbour an hour ago. Before 之前有一段时间时,指距这段时间以前,和过去完成时连用。如:He said he had finished the work two days before. 如果before单独使用,是泛指以前,常常和完成时连用。如:I have seen the film before.
farther 和further:
far 有两种比较级,farther,further. 在英语中两者都可指距离。如:He runs farther than she does.在美语中,farther 表示距离,further表示进一步。 如:I have nothing further to say.
至于副词的比较级和最高级问题,参照形容词的就OK了。
