来源：学生作业帮 编辑：拍题作业网作业帮 分类：英语作业 时间：2024/04/28 00:28:49
辨析hear和heard的区别及应用， 和heard sth. heard about sth. heard sb. doing sth. heard sb. to do sth. 以及 hear sth. hear about sth. hear sb. doing sth. hear sb. to do sth. 区别和正确应用的方法
解题思路： 动词hear是不规则动词。heard是它的过去式和过去分词形式。表现在用hear,表过去，完成或被动就用heard.
解题过程：
hear通常表示某种声音“进入我们的耳朵”。是听到、听见的意思。如：
Suddenly I heard a strange noise.我突然听到一种奇怪的响声。
hear sb / sth doing 表示听某物（某人）正在做某事，强调动作正在进行。
hear sb / sth do表示听到某物（某人）做某事，强调动作已完成。
如：I hear Lucy singing in her room.
我听见露西正在房间里唱歌。
I usually hear Lucy sing in her room.
我经常听到露西在房间里唱歌。
I can hear someone knocking.我听到有人敲门。
hear about =hear of 听说，如：
Have you heard about him from anywhere?你从什么地方听到过他吗？
没有 hear sb to do sth 的用法。但是hear如果变成被动结构时,就必须带to。
也就是说：
hear sb do sth. (主动形式)
be heard sb to do sth. (被动形式)
如：
I often hear him sing the song.
He is often heard to sing the song.
最终答案：略
