he+has+taught
答：句意为当他退休的时候，他已经在二十多个城市从事过绘画教学。教学是在退休之前的事，而句子退休一词已经采用过去式RETIRED，表示过去已经发生，就是他目前已经是处于退休的状态了， 那么 教学一事是为过去的过去，理应采用过去完成时。所以是 had taught.如果句子是这样的，he has taught painting in ...

答：before后面becoming没错，因为作介词的宾语的话要用动名词形式。有上下文背景吗？比如是他教书还是一直被教？现在完成进行时倒是有可能，强调那几年一直在教书……但感觉不太像错误。被教就是has been taught
答：比如：He has been teaching at this High School for 20 years.（他已经在这所高中任教了20年。）表示到说话时，已经教了20年了，目前尚未退休，还会继续教下去，但还会教多久是不确定的。相对比（现在完成时）He has taught at this High School for 20 years.（他在这所高中任教了20年。）...

13948颜钢
： 1. He has taught at this school since 20012. He has been teaching at this school since 2001 第一个句子是现在完成时,注意teach的过去分词是taught,不能写成teached.第二个句子是现在完成进行时.两个句子最主要的区别就是:第一个句子是说他从2001年开始在这里教书,而第二个句子是说他从2001年开始“一直”在这里教书.在第一种情形下,他也可能中间中断过,如出去进修、学习等等,而第二句更强调他一直在这里.
