填空题
No goods (商品) or serves are given free.
As we know, we get many things by payment of money, and people receive money for
so many goods and services. Anyone taking the money from us can in turn spend it
for his own good. For example, the milkman sells the milk for money, and then he
uses the money, possibly, to pay for what is used in his own car. Sometimes the
payment is in another form. Often among friends, or in the family, one person
wilt give goods, or services which cost effort (努力) and skill (技巧) , in exchange
for payment. This might bring a feeling of happiness, such as when one gives a
present. Also, it might show that you have paid the person back, such as when
you help with washing up the dishes after someone cooks you a meal. I means that
in the future the person who gives goods or services will himself be given
something else. No matter how they are paid for -in money, time, or effort -goods and services can only be got by some cost. |
