     I was on a train the other day, in an empty compartment, and I wanted to read the last part of a

detective story. Then the door opened and a mother with two small children asked me, "may we sit here, Madam?" at first I wanted to say, "well, actually, I'm reading an exciting book and I'd like to finish it.

Could you find another compartment?"

     But of course I said, "yes, certainly," I still had not finished that book. Unfortunately, I found it very

difficult to say "No" to those magic words "May I …" or "would you mind if…Of course people usually

ask permission to do quite harmless things, like using the telephone, turning the light on, opening the

window and things like that. But then there are some funny requests. Some people even ask if they may

wash their hands or take their coats off. On the other hand, very few smokers will bother to ask

permission to smoke!

     But what about those difficult requests like, "Do you mind if I come round for a cup of coffee?" or "Is

it all right if I bring the children to the party? They are very good really." The trouble is, I just don't have

the nerve to refuse. Well, do you?

在29届奥运会上，中国代表团以51枚金牌、100枚奖牌高居金牌榜首，彰显了一个体育大国的实力。但从另一方面看，中国还不是一个体育强国，体育强国的判断标准，不是看奖牌榜上有几枚金牌，而是看整体国民的普遍身体素质和体育运动水平。要想真正成为体育强国我们更需要把精力花在全民体育上。

运用政治常识的有关知识，谈谈我国由“体育大国”向“体育强国”转变的过程中，政府应发挥怎样的作用？
