I have just moved to a house in Bridge Street.Yesterday a beggar knocked at my door.He asked me for a meal and a glass of beer.In return for this,the beggar stood on his head and sang songs.I gave him a meal.He ate the food and drank the beer.Then he put a piece of cheese in his pocket and went away.Later a neighbor told me about him.Everybody knows him.His name is Percy Buttons.He calls at every house in the street once a month and always asks for a meal and a glass of beer.
☆ask sb for sth:问某人要什么东西
for：为了这个目的去请求某人。sb更多的时候并不出现，而直接说ask for sth,因为强调的是东西而不是人。
eg:The boy asks (his parents)for money again/once more.
☆in return:作为回报
He doesn't want anything in return.
in return for sth:作为对……的回报
I'll buy a present for him in return for hospitality.
