题型:单项选择题

     The small number of newborn babies, which has been caused by high prices and the changing social

situation of women, is one of the most serious problems in Asia. When people talk about it, you can hear

a word invented in Japan, "DINK", which means Double Income No Kids.

     In many major Asian cities like Seoul, Singapore, and Tokyo, the cost of a house is extremely high.

A young couple who want to buy their own house may have to pay about $3000,000 (though prices

have fallen). For a flat with one bedrooms, one dining-room, a kitchen, and a bathroom, the couple will

pay about $900 a month. What's more, if they want to have a child, the child's education is very

expensive. For example, most kindergarten charges are at least $5.000 a year. In such a situation, it's

difficult to afford children.

     The number of married women who want to continue working because they enjoy their jobs.

However, if they want to have children, they immediately have serious problems. Though most

companies allow women to leave their jobs for a short time to have a baby, they expect women with

babies to give up their jobs. In short, if they want to bring up children properly, both parents have to

work, but it is hard for mothers to work. Indeed, women who want to continue working have to choose

between having children or keeping their jobs.

     In a word, Asian governments must take steps to improve the present situation as soon as possible.
