Passage?One
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 inAsia.When people talk about it,you can hear a word invented inJapan,"DINKS",which means Double Income No Kids.
In many majorAsian cities like Seoul,Singapore,and Tokyo,the cost of a house is extremelyhigh.A young couple who want to buy their own house may have to pay about$300,000（though prices have fallen）.For a flat with one bedroom,onedining-room,a kitchen,and a bathroom,the couple will pay about$900 amonth.What′s more,if they want to have a child,the child′s education is veryexpensive.For example,most kindergarten charges are at least$5,000 a year.In such a situation,it′s difficult to afford children.
The number ofmarried women who want to continue working increases rapidly because they enjoytheir jobs.However,if they want to have children,they immediately haveserious problems.Though most companies allow women to leave their jobs for ashort 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 towork,but it is hard for mothers to work.Indeed,women who want to continueworking have to choose between having children or keeping their jobs.
In a word,Asiangovernments must take steps to improve the present situation as soon aspossible.

Every year gray whales migrate from the Bering Sea in Alaska to the Baja Peninsula in Mexico.
Eleven gray whales have died in the San Francisco Bay in the last three weeks．No one knows why the whales are dying.
Last year 270 whales died along the whales'migration route．Many people think starvation is the cause．This year the dead whales seem to have more blubber(fat)on them.
Twenty years ago,the gray whale was listed as an endangered species.
Some scientists think that the larger number of whales makes it hard to find enough food．More whales create more pressure on the food supply,a supply that some scientists say may have dwindled as a result of the warm waters of El Nino.
Most of the whales have been dead for many days before they are found and studied．This makes it hard to find the reason for death.
65 whales have been seen in the San Francisco Bay Area this year compared to 17 last year．The whales could be dying from many diseases,but it may be over-population．

One reason it is difficult to know why the whales are dying is that__.

A.the whales travel such a long distance
B.there are more whales than there used to be
C.the whale bodies are too old to study by the time they are found
D.the whales are endangered
