【拓展提高】 1.hear和listen to
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________ a strange noise.我突然听到一个奇怪的声响。

I can ________ you.我能听到你说话。

_________ me please.请听我说。

I _____ them talking in next room,but I didn‘t really ____________ 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 ________ 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。

2.被动语态语态是动词的一种形式，它表示主语和谓语的关系。

语态有两种：主动语态和被动语态。

如果主语是动作的执行者，或者是说动作是由主语完成的，要用主动语态；如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。
