动词hear是我们最常用的词，也是试题中常见的词。它可以用作打洞词或打洞词，要注意的是不需要做时态。

hear可以用做不及物动词，它的意思是“听，听见”。比如：I can’t hear very well.我听觉不太好。Don’t believe all the gossip you hear.别对那些道听途说都信以为真。

hear from表示“收到消息”。比如：I have not heard from him for a long time. 我好久没有收到他的来信了。需要注意的是：hear from多指通过信件获知消息。

hear of表示“知道，了解某人或者某事的存在”，一般用在疑问句或否定句中。比如：Have you heard of the story?你听说过这个故事吗？Who is he? I’ve never heard of him.他是谁？我从来没听说过他。

有时我们可以用hear about，它的意思是“得悉，听说”。比如：I’m pleased to hear about your news.听到你的消息我很高兴。Have you ever heard about Tom jumping into the pool with all his clothes on?你听说过汤姆穿着衣服跳进游泳池的事吗？

Hear后面可以跟that引导的从句。比如：I hear that you’ve been awawy this weekend.我听说你这个周末外出了。He heard that there was an election last week.他听说上周有个选举。

在hear sb do sth结构中，动词不定式符号to要省掉，这是考点之一。比如：I heard her say so .我听见她是这么说的。Did you hear him go out ?你听到他出去了吗？

hear sb or sth +过去分词，表示“听说某事被做，某人被…”。比如：I've often heard that said.我常听说那种说法。I've often heard him called that name.我经常听人家叫他这个名字。

hear sb /something+动词-ing形式表示“听到某人/某物正在……”。比如：I hear him coming.我听见他来了。I hear the bells ringing.我听见铃声在响。coming和ringing都表示正在发生的动作。I can hear a dog barking.我听到犬吠声。

被动结构be heard后边可以跟动词不定式。比如：He was heard to observe that he did not agree with Jane.听说他不同意简的意见。
