hearf of 和hear from的区别

hear, hear of, hear from
hear可用作及物动词,表示“听到”、“听见”,侧重于听的结果.如：
I'm very sorry to hear that.听到那件事我非常难过.
Hear后面还可以跟that从句,如：
I hear that you've been here for several years. 我听说你已经来这儿几年了.
(2) hear of是“不及物动词+介词”构成的词组,意指间接地“听到”“听说”后接名词性质的词.如：
I have never heard of him before. 我以前从来没有听说过他.
注意：hear of与hear about的意义相近,这两个词组在英语中有时可以通用.它们含有“听人说起”,“从书报上看到关于”等意义.例如：
I’ve never heard of him. 我从来没有听说过他.
Have you heard about him from anywhere?你从什么地方听到过他吗?
(3) hear from指“收到……的来信”与get or receive a letter from 同义,其宾语应是人,而不是信.如：
I often hear from my parents.我经常收到父母的来信.

hear of + 名词 听说....
hear from + 名词 从...（哪里）..听说

hearf of听说
hear from收到（某人的）来信

跟第一个回答的一样

hear of +名词, 通常指某人或事.
如, 很久没有听到关于他的消息. IT'S A LONG TIME THAT I DID NOT HEAR OF HIM.
hear from +名词, 指从哪里听到或者知道这件事.
如,这件事我是从他姐姐那里知道的. THIS WAS HEARD FROM HIS SISTER.
