talk to 与 speak to的区别.

1、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。

〖 点拨〗say ,speak ,talk 及 tell 的区别：
say：是最口语化的最普通的一个词,意为“说出”、“说道”,着重所说的话.如：
“I want to go there by bus” ,he said .他说,“我要坐汽车到那里去.”
What is he saying?
He said his name was Tom .
speak :“说话”,着重开口发声,不着重所说的内容,一般用作不及物动词 ( 即后面不能直接接宾语 ) .如：
Can you speak about him?
I don’t like to speak like this .
〖 点拨〗speak 作及物动词解时,只能和某种语言等连用,表达在对话中恰当使用词汇的能力.如：She speaks English well .
talk :与 speak 意义相近,也着重说话的动作,而不着重所说的话,因此,一般也只用作不及物动词,用作及物动词时,宾语只能是某国语言等少数几个词.不过,talk 暗示话是对某人说的,有较强的对话意味,着重指连续地和别人谈话.如：
I would like to talk to him about it .我想跟他谈那件事.
Old women like to talk with children .
give a talk 作报告
tell :“告诉”,除较少情况外,一般后面总接双宾语.如：
He‘s telling me a story .
tell a lie 撒谎
