动词 “hear” 和 “listen” 都可以描述 “听” 这个动作，但它们的用法却不同，所以不能互换使用。哪个词可以表达 “听音乐” 的 “听”？哪个词的意思是 “听到声音”？
 
Hi! I'm Roy, and today I'm going to tell you the difference between two words that are often confused: hear and listen.
Hear is the verb we use to talk about the ability. It doesn't mean that we want to hear something. It's about sounds coming to our ears.
I can hear the air conditioning. It doesn't mean that I want to hear it, but I can.
The verb listen is often followed by the preposition 'to'. We use this verb when we're paying attention or focusing on sounds.
I hope you're listening to me. That means I hope you're paying attention.
Compare these two sentences:
I can hear some music (somewhere).
I am listening to some music. I'm listening to a song that I want to listen to.
Anyway, I've got to go. I can hear my boss calling me.
 
用法总结
1. 动词 “hear” 描述的是 “可以听到” 的能力，表示声音进入耳朵是无意识的动作，与这个人的意愿无关。
I can hear the air conditioning. 
I can hear my boss calling me.
He heard something and woke up.
 
2. 动词 “listen” 强调有意识的 “去听，注意听”，或 “倾听”，后常接介词 “to”。
I hope you're listening to me.
Listen! Who's there?
You should listen to your parents.
 
3. 对比下面两个句子，记忆 “hear” 和 “listen” 的含义和用法。
I can hear some music.  （我能听见有音乐声）
I am listening to some music.  （我在听我想听的音乐）
