一、Chinese parents tend to pay so much attention to their children's academic performance that they even don't involve their children in the housework. Their only requirement of their kids is to study hard, perform well in exams so that their kids can be admitted to  prestigious universities. They are convincedthat this is to the benefit of their children, because only good academic performance can guarantee apromising future for their kids in the inense competition typical of China. They also believe that they will be respected if their children make great achievements in society. Therefore, they are willing to providetheir children with a better condition at the expense of their time, hobbies and interests.

中国父母往往过于关注孩子的学习，以至于不让他们帮忙做家务。他们对孩子的唯一要求就是努力学习，在考试中取得好成绩，最终考上名牌大学。他们相信这是为孩子好，因为在中国这样竞争激烈的社会里，只有成绩好才能保证前途光明。中国父母还认为，如果孩子能在社会上取得巨大的成就，父母就会受到尊敬。因此，他们愿意牺牲自己的时间、爱好和兴趣，为孩子创造更好的条件。

二、Prices determine how resources are to be used. They are also the means by which products and services that are in limited supply are rationed among buyers. The price system of the United States is acomplex network composed of the prices of all the products bought and sold in the economy as well asthose of a variety of services, including labor, professional, transportation, and public   services. The interrelationships of all these prices make up the “system" of prices. The price of any particular productor service is linked to a broad, complicated system of prices in which everything seems to depend more or less upon everything else.

价格决定了资源如何使用。同时，由于产品和服务的供应有限，价格还是在消费者之间合理调配这些产品和服务的一种手段。美国的价格体系是一个复杂的关系网，既包括国民经济中进入买卖的所有产品的价格，也包括种类繁多的服务价格，如劳务服务、专业服务、运输服务及公共服务等。以上各种价格之间的相互关系，构成了整个价格体系。任何一种特定产品或服务的价格都与一个广泛而复杂的价格体系有关。在这一体系中，任何东西与其他东西似乎多多少少都构成相互依赖的关系。
