在英语里，表示“听”的单词最常用的有listen和hear两个。可能很多人十年寒窗苦读英语都没分清这俩的区别，它们的关系其实很简单，一张图就能表达：
Listen 表示有意识地去听，并包含“去听”这个动作；
Hear 多表示无意识地听见，耳朵收到声音讯息就算
如果互换两个词，意思就会大变，如：
listen to me
hear me
listen to the music
hear the music
listen to the teacher
hear the teacher
listen to the thunder
hear the thunder
他俩最简单的区别就是“有意和无意”这么简单。而其它的区别则是语法：
Listen
这是个“不及物动词”，也就是不能直接跟名词，中间必须加个介词，比如“listen to music”。
listen to …
I like to listen to music when working.
listen for …
Listen for the moment when the music changes.
listen in
When the news is on, you should listen in.
listen in on …
It sounded like someone was listening in on us.
listen out
Listen out for the baby in case she wakes up.
listen up
Hey everybody, listen up!
Hear
这是个“及物动词”，正好与listen相反，后面可以直接跟名词，比如“hear sound”。
hear …
Can you hear me?
hear … doing …
Jenny could hear them fighting outside.
hear … do …
She heard Tom go upstairs.
be heard to do …
She didn't want to be heard leaving the office.
hear about …
Teresa heard about a job that would be perfect for you.
hear of …
I've heard of that person – he’s famous.
这里也要注意，当hear表示无意识的“听”时不能用于进行时态。举几个例子，个简单的例子，就是不能说“I’m hearing you”，而要说“I can hear you”。
还有一些常用语注意事项如下：
1. 当别人说话时问你是否在听，你应该回答“I’m listening”而不是“I’m hearing”。
2. 要问别人是否听得见你说话，应该问”Can you hear me“而不是”Are you listening“，这是”你在听吗“的意思。
3. 当提醒别人注意“听”的时候，应该说“Listen.”而不是“Hear.”。
4. “Listen up”是“听好了”的意思，一般接着你要让别人听的话，带有命令的口吻，不太礼貌。
