请问speak,talk,say他们有什么区别？

<1>Speak, Talk, Say和Tell
Speak比较庄重，表示某人(即讲者)在一段对话中所说的话较其它人多。
举例：

The Principal speaks to us every morning at the assembly.

Tom, your boss wants to speak to you.

Talk不及speak庄重，而且多用于说话，少用于书写。 Talk表示两个或更多的人在对话。

举例：

The students were talking loudly in the classroom, in the very presence of the teacher.

当宾语是一种语言时，要用 speak 不用 talk 或 say：

正确： Victor speaks fluent Putonghua.

错误： Victor talks fluent Putonghua.

错误： Victor says fluent Putonghua.

在书面英语， talk 极少用作及物动词，除非在 talk 后接用以下的宾语：

Stop talking nonsense.

They are talking business again.

若不是接用上列的宾语，talk 后必需接用前置词 about。
举例：

正确： Betty and Susan are talking about the trip to London.

错误： Betty and Susan are talking their trip to London.

Say通常跟讲者所说的话一起使用，不论是直述句或陈述句：

Please say hello / thank you to your mum.

What did your father say when you told him about your plan to get married? 'I cant believe it,' he said.

He said that he could not believe it.

可是， say 有时也可用于一些非直述句或陈述句中。

看看以下的例子：

I want you to say something about how we met at our wedding party.

注意 something about how we met并不是用于引述别人所说的真实语句。

另一方面， tell 并不是用于引述别人所说的话语，而是表达别人的说话中所述的事实或资料：
He told me about the accident.
He told his parents the truth.

He told us a funny story.

<2>see的意思是“看见”、“看到”，通常指不知不觉地通过视觉看见物体，可能是有意识地看也可能是无意识地看，着重强调看（look）的结果。see可用作看电影，看戏剧。例如：

It was clark and we couldn’t see anything．

Are you going to see the film this evening？

watch的意思是“观看”、“注视”，强调注意力的集中，常指有意识地注视正在发生或将要发生的事情，后面跟的宾语往往是正在活动的人或物。例如：

We are watching TV now．

Are you going to watch the football match．

、speak———“说”、“讲”、“演讲”。做及物动词时，宾语常是表示语言的词。例如：

Do you speak Chinese?你说汉语吗？

Mr.Wu is going to speak at our class meeting.吴老师将在班会上发言。

2、talk———“讲”、“说话”、“谈话”，与speak的意义相近。一般用做不及物动词，指一般的谈话或交谈，而不如speak正规的“演讲”、“发言”，须跟宾语时，与to、with、about等介词连用。例如：Jim is going to talk about English names tomorrow.吉姆明天打算谈谈英国人的名字。

Look!Our teacher is talking

to(with)theparents.瞧！我们的老师正在和家长们谈话。

3、say———一般着重讲话的内容，指有连贯性的说话，通常用做及物动词。例如：

Idon’t know what he said.我不明白他所说的。

Kate saw a card on her

table,itsaid：“Happybirthday!”

凯特看见桌上一张卡片，上面写着：“生日快乐！”

4、tell指把一件事情传达给别人或讲述一件事情、一个故事等。常用做及物动词。

例如：WhenIwasyoung,mymotheroftentoldmeastoryin

theevening.在我小时，妈妈晚上常给我讲故事。

Hewilltellthegoodnewstoeverybodyinourclass.他将把这个好消息告诉我们班的每个人。
__________________________

look是强调看的动作。例：look！it is a bird.
see是强调看的结果，强调的看得见看不见。例：i can see a bird.
watch用在看电视看比赛的时候。例：let's watch tv together.

look at是look的短语，look本身是不及物动词，如果它要带宾语的话，后面就必须要有一个介词，所以有look at这个短语，意思是看着某某。例：look at the blackboard,everyone.

speak、say、talk词语难点解析
【设疑】speak、say、talk
有何区别？
【解惑】speak、say、talk
这三个词都有"说、讲"的意思,但它们在用法上有区别。speak侧重指说话的能力及方式,尤其指说语言；say是及物动词,侧重指说话的内容；talk是不及物动词,指连续不断的说话或交谈,常与介词to、with、about等连用。试比较:①He
can
speak
English.
他会说英语。②
What
did
you
say？你说什么？③We
are
talking
about
you.我们正在谈论你。

speak,talk,say都是说

谢谢
