参考答案:B

解析:私人物品的生产者能够决定谁可以获得此物品既谁支付了价款,谁才可以得到(竞争性),因此私人物品意味着私有的权利;公共物品则不行,它一经生产出来,生产者就无法决定谁将得到它,不付费的人也可能获得它并消费使用它 (公共性)。

      Happiness is for everyone. You don't need to care about those people who have beautiful houses with large

gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those

who have big houses may often feel lonely and those who have cars may want to walk to the country roads in

their free time.

      In fact. Happiness is always around you if you put your heart into it. When you are in trouble at school,

your friends will help you: when you study hard at your lessons, your parents are always taking good care of

your life and your health; when you get success, your friends will say congratulations to you; when you do

something wrong, people around you feel unhappy, too. All these are your happiness. If you notice a bit of them,

you can see that happiness is always around you.

      Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you

are very happy, because you have something else that can't be bought with money. When you meet with

difficulties, you can say loudly you are very happy, because you have more chances to challenge (挑战)

yourself. So you cannot always say you are poor and you have bad luck. As the saying goes, life is like a

revolving (旋转的) door. If you take every chance you get, you can be a happy and lucky person.
