人民币是我国的法定货币。人民币的流通，是我国国民经济、人民生活赖以维持和发展的血脉。

（1）我们手中的人民币为什么能购买自己需要的商品？

______________________________________________________________________________________________________________________________________________________________________________________

（2）人民币作用这么大，国家能否通过多印发人民币来提高人民的生活水平？

____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

答案

（1）人民币是我国发行的、强制使用的价值符号，它代替货币执行流通手段的职能，在商品交换中起媒介作用，所以人们持有人民币就能购买自己需要的商品。

（2）国家有权发行人民币，但不能任意发行。人民币的发行量必须以流通中所需要的货币量为限度。如果纸币发行量超过这个限度，就会引起物价上涨，影响人民生活和社会的经济秩序。要提高人民的生活水平，必须保持经济的稳定增长，增加居民收入。所以，国家不能通过多印发人民币来提高人民的生活水平。

根据短文内容，完成下列句子，每空词数不限。

     Soda is popular all over the world. People, especially young children, like drinking it very much because

it tastes good. Some of them drink at least one can or bottle every day. But drinking it not only costs too

much money, but also is bad for people's health in some ways. If you drink too much soda, you will probably

become too fat, have a toothache. Even if you don't mind your money, you must at least care about your health.

     Why is soda unhealthy? A study at a university has been made for years. It shows us how bad it is. First,

soda can lower your body's PH levels. Second, soda can raise insulin levels (胰岛素水平), lead to high blood

pressure (血压), heart disease, weight gain and so on. Do you want your teeth to stop falling out? Stop

drinking soda! Do you want your bones (骨骼) to get harder? Stop drinking soda! Do you want to improve

your immune system (免疫系统)? Stop drinking soda! Do you want to lose weight? Stop drinking soda!

     But what should you drink instead? Water is good for your health. Drinking tea is a good idea, too. Anyhow, you should stop drinking soda from now on.
