英语辨别题talk, speak, say, tell如何区别【注：麻烦中点说明talk和speak的区别,即什么情况下用哪一个,谢了!）我希望尽可能简洁明了，拜托咯！！

TALK, SPEAK, SAY, TELL: As a general rule, these verbs
can often have more-or-less the same meaning if the construction is changed accordingly (see the examples which start in the next box)
can vary considerably if used idiomatically, or as a phrasal verb (see the practice below)
SPEAK = TALK (same construction)
He is (in the middle of) speaking/talking to John
However, you cannot use SAY & TELL unless you change the construction
He is (in the middle of) saying something to John
He is (in the middle of) telling John something
SPEAK = TELL (different constructions)
Speak to him now = Tell him now
Speak to as many people as you can = Tell as many people as you can
TALK v SPEAK v SAY v TELL used in the imperative
SPEAK is often used in the imperative with an adverb or adverbial phrase
Speak quietly, etc.
Speak as loud as you can
TALK is rarely used in the imperative, but can carry a negative message
Talk to him if you must, (but I don’t want you to) (=If you insist on speaking to him, do so)
Don’t talk (=Say nothing)
Talk among yourselves
TELL is often used in the imperative for messages
Tell him I need some money
Tell him I will be back soon
Tell him I’ve gone to the shops
SAY is used in the imperative for wanting something said to you
Say something (to me) please (=speak to me )
Say something nice (= tell me something nice)
Say yes/Say no (= tell me you want/don't want to)
