“情态动词＋have＋过去分词”的用法
英语中，表示对过去某种情况进行推测或对已发生的动作或存在的状态进行推测，常用情态动词must, may, might, can, could, should, ought to, would等＋have＋过去分词表示。一般来说，说话人的语气或推测的把握程度不同，使用的情态动词也不同。现分述如下：
1. must＋have＋过去分词：表示对过去发生的动作或存在的状态进行推测。只用于肯定的陈述句中(在否定句及疑问句中用can ),意思是“一定已经”。例如：
If he had really been there, I must have seen him. 如果他当时确实在那里，我一定会看见他。
Her watch must have stopped. I will go and call her. 她的表准是停了。我去叫她。
2. may／might＋have＋过去分词：表示对过去发生的动作或存在的状态进行不肯定的推测，即说话人认为过去某事发生的可能性或某状态存在的可能性一般。可用于肯定句（意思是“可能已经”）和否定句（意思是“可能没有”）；might的语气没有may那么肯定。例如：
She may have read the book. 她可能已经看过这本书了。
He might not have got your letter. 他或许没有收到你的来信。
3. can／could＋have＋过去分词：表示对过去某种行为或存在的状态的怀疑或不肯定推测。can 常用于否定句（意思是“不可能已经”）和疑问句；could 除用于否定句及疑问句外, 还可用于肯定句（意思是“那时可能; 本来可以”）。例如：
Don’t worry―they could have just forgotten to phone. 别担心――他们很可能只是忘了打电话。
Where can he have gone? 他可能去哪里了呢?
4. need＋have＋过去分词：该句式常用于否定句，表示过去做了不必做或不需要做的事情或过去做某事纯属多余，含有“根本不必；本来不必”之意，也可用于疑问句。例如：
You needn’t have told them that. 你没有必要告诉他们那个。
Need they have done it last week? 他们上周做这事有必要吗?
5. should／ought to＋have＋过去分词：肯定式表示“过去本应做某事（但没做）”；否定式表示“过去不该做某事（但做了）”。该句式含有不满或责备之意。例如：
You’re right. I should have thought of that. 你说得对。我应当想到那点（但没想到）。
She ought to have been more careful. 她本该更小心些。
6. would＋have＋过去分词：表示过去本来要做某事却因某种原因未做，通常用来说明某种情况，但不像用 should 或 ought to 那样含有责备之意。例如：
I would have written to you earlier but I have been ill. 我本来要早点给你写信，但我生病了。

分词就是具有及二者特征的词，尤指以-ing或-ed,-d,-t,-en或-n结尾的英语动词性形容词，具有形容词功能，同时又表现各种动词性特点，如、、带状语性修饰语的性能及带宾词的性能。分词分为和两种，是一种形式。现在分词和过去分词主要差别在于：现在分词表示“主动和进行”，过去分词表示“被动和完成”（不及物动词的过去分词不表示被动，只表示完成）。分词可以有自己的状语、或逻辑主语等。外文名participle特&&&&征具有及二者特征表&&&&示被动和完成语&&&&法形式
分词作状语
分词在中作状语，可以表示时间、条件、原因、结果、让步、方式、伴随等。
分词（短语）作状语时，其逻辑应与句中主语相一致。.当表示的动作发生在动词之前时, 则用现在分词的完成式,当所表示动作与谓语动作同时发生, 则用现在分词的一般式。完成或被动关系用。
（1）现在分词The students went out of the classroom, laughing and talking.
（2）过去分词Accompanied by his friend, he went to the railway station. Given better attention, the plants could grow better.
&while ( when, once, until, if , though等从属)+分词&结构
现在分词或过去分词作状语时，有时可以在分词前加while，when, once, although, until, if等。
When leaving the airport, she waved again and again to us. While waiting for the train, I had a long talk with my sister about her work……
Once recovered, he threw himself into his work and made every effort to do it well.
Although working very hard, he failed to pass the final exam. If translated word by word, the passage will be difficult to understand.
分词作定语
分词作定语时，单个的分词通常放在被修饰的名词之前，单个分词作定语置于被修饰词的前面，分词短语作定语，置于被修饰词的后面。现在分词修饰的是发出该动作的名词(即与名词有主谓关系)，过去分词修饰承受该动作的名词(即与名词是)。

This is really an exhausting day to all of us!
We can see the part of the moon lighted by sunlight.

分词作宾语补足语
现在分词在see, watch, hear, observe, notice, feel, find, glimpse, glance等和look at, listen to等以及have后面，与名词或构成，作的成分，有三种形式，即动词原形，现在分词和过去分词。动词原形表主动和完成，现在分词表主动或正在进行，过去分词表被动或完成。
分词作通常看作来用。现在分词表示主语的性质，而且主语多为物；过去分词表示主语的感受或状态，主语多为人。

The theory sounds quite convincing.He was very amusing.
