[单选题]在南极海域冰冷的海水中，有一种独特的鱼类，它们的血液和体液中具有一种防冻蛋白，因为该蛋白它们才得以存活并演化至今。但时至今日，该种鱼类的生存却面临巨大挑战。有人认为这是海水升温导致的。

A.防冻蛋白能够防止水分子凝结，从而保证南极鱼类正常的活动，气候变暖使得该蛋白变得可有可无

[单选题]We first think of the traditional or nuclear family．This is a two-generation family,the father and the mother and their own children．Most couples wanted to have four children,two boys,two girls.
Some nuclear families,however,may add one or more grandparents to come to live with them,that is three generations．This kind of family with grandparents,parents,and grandchildren is called an extended family．This family type was not very common during the later half of the twentieth century,but it's becoming more common now as an elderly grandparent moves in to live with a son or daughter．This is more possible now that American homes have become larger．What is interesting,however,is that after the grandchildren move out of the home and start their own families,this extended family shrinks back to a nuclear family,with just two generations again living together,a grandparent and parents,with the grandchildren coming only for occasional visits．
Now,the fatherless or motherless family is one kind of what we call a single-parent family．In the fatherless family it's just the mother and her children．As I said,this can be the result of the husband's death,of an unmarried mother,of a separation or divorce．There are also a growing number of motherless families--where the father raises the children,for any of the same reasons．A motherless family may also be fatherless,but still a family with one adult．This is becoming more common in the big cities where a grandmother will raise her daughter's children while the daughter goes elsewhere to work.
One other new kind of family is becoming increasingly more common．A single parent with one or more children will marry again．Perhaps the other parent is also a single parent．Together they will start what is called a blended family,which blends together or combines the children from two other families.
Who usually looks after the children in a both motherless and fatherless family in America?
A.The children's aun
B.The children's nursery or schoo
C.The children's grandmothe
D.The children's neighbou

Just a few weeks ago,
economists and market analysts were expecting the Federal Reserve to cut
short-term interest rates one final time when policy-makers gather for their
first meeting of the year Tuesday and Wednesday. Now the vast majority of
analysts believe the central bank’s aggressive year long rate-cutting cam paign
is over, and the focus already is turning to when the Fed will begin raising
rates again.
Based on weekly unemployment data, the rate of job
reductions is slowing, and almost every economic indicator reported over the
past several weeks has been encouraging. Fed Chairman Alan Greenspan had reason
to be optimistic on Jan. 24, when he testified before a Senate panel and seemed
far more {{U}}upbeat{{/U}} about the economy than be had been just two weeks earlier
in a speech that sparked a Wall Street sell-off.
Analysts now
believe it is almost a sure hat the Fed will leave rates unchange
