listened to和heard的区别？

hear和listen to 的区别：
hear只是强调听见了，指声音传进了耳朵。
listen to的意思是集中注意力，尽量听清楚。
例如：
Suddenly I heard a strange noise.我突然听到一个奇怪的声响。
I can hear you.我能听到你说话。
Listen to me please.请听我说。
I heard them talking in next room, but Ididn‘t really listen to what they were saying.
我听到他们在隔壁房间里说话，但我实在没注意听他们说什么。
当谈到听音乐、无线电广播、演讲、讲课等时，要用hear。
Did you hear Jack’s talk on Tuesday? 你听了星期二杰克的演讲吗？
但是可以说：I spent the night listening to records. 我听了一晚上的唱片。（不是公开演出）
注意：hear一词一般不用于进行时。不说I am hearing或I was hearing，而用can或could。例如：I can hear somebody coming.我能听见有人来了。
