我还没学现在完成时,
They have been waited for twenty minutes.这个句子中有一处错误,请指出并改正我还没学现在完成时,
waited改成waiting
这是一个现在完成进行时句式.
其构成为：主语+助动词（have/has）+been+动词的现在分词+其他成分.
waited改为waiting 这个是完成进行时
Thay habe been waiting for ....
现在完成进行时，动词 要可持续性的，表示：动作在现在时间点之前已经开始还要继续下去（还没停止）
have been 是被动态 应去掉been 此句翻译为他们已经等了20分钟 等待为主动 所以不加been
waited改为waiting
这里主要区分的是主动和被动。be done是被动，句子表达的应该是“等”而不是“被等”，所以不能用be waited.
