试论述“一国两制”构想的内容。

One potential prolem with allowances (零用钱) is that children’s reponsible behavior can become about earning the allowance rather than the intrinsic (固有的) value of their family responsibilities. For example, if you pay your children for taking out the trash, they see this chore (家务事) as a job that they should be rewarded for instead of a responsibility they must fulfil as part of the family. But giving children an allowance for weekly chores is not necessarily bad. You are rewarding them for fulfilling their family responsibilities, but it is not for a specific act. Rather, it is an appreciation of their commitment to your family values.You are also conveying another important message that their actions have consequences: if they do good things, good things happen. They also learn a lesson about the market economy, namely, that work is rewarded.

Allowances can also be used as punishment and to teach children lessons about family values. For example, if your children join a group of kids smashing (炸碎) pumpkins on Halloween, a part of a reasonable punishment might be to require them to pay the families out of their allowances to replace the pumpkins. Thus, your children learn that bad behavior has financial consequences. Also, by relating the punishment to the misdeed, you ensure that your children see the connection and learn the value lesson.

How much allowance should you pay your children? The precise amount depends on your family’s financial situation, the cost of living and your children’s needs. Children can start to earn a weekly allowance as early as 5 years of age. An increase of $1 per week for each year of your children’s lives is realistic until they reach their mid-teens. When they begin to drive and date, you can calculate their expenses and establish a reasonable allowance that covers their needs.
