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

Multivitamins Urged for All Pregnant Women A recent study in Tanzania found that when pregnant women took vitamins every day, fewer babies were born too small. Babies that weigh less than two and one-half kilograms at birth have a greater risk of dying. Those that survive are more likely to experience problems with their development. And experts say that as adults they have a higher risk of diseases including heart disease and diabetes. The World Health Organization estimates that every year twenty million babies are born with low birth weight. Nine out of ten of them are born in developing countries. The new study took place in Dar es Salaam. 4,200 pregnant women received multivitamins. The pills contained all of the vitamins in the B group along with vitamins C and E.
