有没有be heard doing的说法
看一个例句：he is heard to sing now./he was heard to sing just now 这里为什么用sing,我想都是短暂的动作不应该用singsing吗?

有be heard doing 的用法.请看例句：
1.I often hear him sing in the morning.(改为被动语态）(我经常听到他早晨唱歌,hear sb.do sth.）
He is ofen heard to sing in the morning.
2.I heard him singing just now.(改为被动语态）("刚才我听到他正在唱歌”hear sb.doing sth.）
He was heard singing just now.

有没有be heard doing的说法请问be heard to do/do/doing之间的区别以及是否存在be heard do 的说法有没有be not weak in doing sth的说法?be not well in可以这么用吗? 有没有be fun with,be fun to do和be fun doing这些说法? 有没有be like+be doing的语法结构? 有没有persuade sb from doing sth的说法呢? 有没有make a decision of doing sth.的说法? be heard to do be be heard to be doing be heard doing be hea 有没有be have been的说法? 1.be heard to do与be heard doing的区别有没有 want doing 这种说法? be done doing 的说法正确么
