last for、go on 、keep up都是些神么意思啊,一般怎么用?

last (for),last 在这里是动词,表示延续了,后边接具体时间单位的时候可以去掉for或其他介词,如 last an hourgo on,非常常用,意思也很多,我主要写几个,1,表示继续下去 ,go on doing sth.(with) He went on crying unt...keep up 等于continue 可以举个例子吗？先用continue，然后换上。。。 然后， go on to do sth.麻烦也举个例子 然后，插上个题外话：stop to do sth、，也举个例子好吗，顺便附上什么意思OK, 1: How long can the wedding keep up(continue)? 这个婚礼能持续多久?2, 区别一下 He went on eating his pie. After finishing the pie,he went on to eat the icecream.那那stop to do sth呢？OK, 1: How long can the wedding keep up(continue)? 这个婚礼能持续多久?2, 区别一下 Then he stopped talking, and went on eating his pie. After finishing the pie,he went on to eat the icecream.3.stop to do sth. 指的是停下手里做的事去做另一件,和 stop doing sth值得就是停下手里的事情.He spent the whole morning fixing his car, but at 12 o'clock he stopped to have lunch.就是说to后面接的事情是接下来要做的，而不是要停下来的？是的,不定式形式大多都是这个感觉, 还有remember doing sth. 记得做过什么事情,和remember to do sth. 别忘了要去做什么
