[不定项选择题]共用题干 They Say Ireland's the Best

Ireland is the best place in the world to live for 2005,according to a life quality ranking
that appeared in Britain's Economist magazine last week.
The ambitious attempt to compare happiness levels around the world is based on the
principle that wealth is not the only measure of human satisfaction and well-being.
The index of 111 countries uses data on incomes,health,unemployment,climate,
political stability,job security,gender equality as well as what the magazine calls
"freedom,family and community life".
Despite the bad weather , troubled health service , traffic congestion（拥挤）,gender
inequality,and the high cost of living,Ireland scored an impressive 8.33 points out of 10.
That put it well ahead of second-place Switzerland,which managed 8.07.Zimbabwe,
troubled by political insecurity and hunger, is rated the gloomiest（最差的）,picking up only
3.89 points.
"Although rising incomes and increased individual choices are highly valued,"the
report said,"some of the factors associated with modernization such as the breakdown（崩
溃）in traditional institutions and family values in part take away from a positive impact."
"Ireland wins because it successfully combines the most desirable elements of the new
with the preservation of certain warm elements of the old,such as stable family and
community life."
The magazine admitted measuring quality of life is not a straightforward thing to do,and
that its findings would have their critics.
No. 2 on the list is Switzerland.The other nations in the top 10 are Norway,
Luxembourg,Sweden,Australia,Iceland,Italy,Denmark and Spain.
The U.K. is positioned at No. 29,a much lower position chiefly because of the social
and family breakdown recorded in official statistics.The U.S.,which has the second
highest per capita GDP（人均国内生产总值）after Luxembourg, took the 13th place in the
survey.China was in the lower half of the league at 60th. Family life in Zimbabwe is not stable.
A.Right
B.Wrong
C.Not mentioned

[简答题]Things aren’t always as they appear, a fact of life confirmed for me firsthand in 1990, just after I received my Ph.D. in physics. I had just started a temporary postdoctoral position at a major laboratory and had the opportunity to talk with scientists whose postdoctoral fellowships were ending. 21) Although my advisers had warned me that finding a permanent position in science would be difficult, what I discovered was shocking — even the best young scientists I knew were having difficulty securing permanent employment. So it was both puzzling and disturbing to see press reports claiming that America didn’t have enough scientists.
These alarming reports were epidemic in 1990. Frequently the news stories had hyperbolic headlines like SHORTAGE OF SCIENTISTS APPROACHES A CRISIS AS MORE STUDENTS DROP OUT OF THE FIELD, and they often quoted National Science Foundation (NSF) officials. 22) For a government obsessed with international competitiveness, stories of a shortage o
