1)

　W:Hey,Sam,I have a question for you.

  Mlaughs)All you have to do is ask?  

  I can't understand what's the man's attitude.why he say so? but ,next he helped the woman to solve the problem.In Chinese,this sentence means you are asking all the time!for me I will misunderstand the speaker's real purpose.So can you tell me more about it?The more examples,the better!Thanks!

2)

  Here ,the next problem is

  The situation is that there'a man that he ain't know the profesor's lecture,so he ask the girl ,the girl explain it him,at last ,the man know what she say,then the girl say,usually not just after the trip up.Focus on the sentense! I can't get across it.Some tips?

3)

Subsequently,

the profeser laughs)Uh,no,not really.It's just a folktale,and the groundhog isn't....um...{batting much more than fifty-fifty}.

That is what I don't know.

  What  if you have suffient time.Thanks a lot!
