The average population density of the
world is 47 persons per square mile. Continental densities range from no
permanent inhabitants in Antarctica to 211 per square mile in Europe. In the
western hemisphere, population densities range from about 4 per square mile in
Canada to 675 per square mile in Puerto Rico. In Europe the range is from 4 per
square mile in Iceland to 831 per square mile in the Netherlands. within
countries there are wide variations of population densities. For example, in
Egypt, the average is 55 persons per square mile, but 1,300 persons inhabit each
square mile in settled portions where the land is arable. High
population densities generally occur in regions of developed industrialization,
such as the Netherlands, Belgium, and Great Britain, or where lands are
intensively used for agriculture, as in Puerto Ri A. there is dense population B. we may expect to find malaria-infested jungles C. the density of population is relatively low D. good quality land is found

[单项选择] Passage Four
Today the average worker is paid less than $ 4 an
hour in Portugal and $ 9 an hour in Spain, compared with $13 in Germany and
almost $16 in Denmark. Taking accounts of non-wage costs, such as employer’s
social-security contributions, the gap is wider still: from $ 6 in Portugal to $
24 in Germany. With the EC’s single market knocking down barriers in
intra-European trade, no wonder German companies now seem keener on sunnier
climes. But how long will southern Europe’s cost advantage last
Conventional wisdom argues that greater economic integration within the
single market, and later under a single currency, will cause wages to converge.
Increased labor mobility, for example, should allow worker to move from
low-wage to high-wage economics. Increased trade and cross-border investment
should also push labor costs closer. The e A. decreased trade and cross-border investment push the labor costs lower B. labor mobility and the easiness of communicating allow worker to migrate C. the pace of convergence is seemingly stepping up at a higher rate D. the southern Europe’s cost advantage will last for a while

[单项选择] Passage Two
On an average of six times a day, a
doctor in Holland practices “active” euthanasia (安乐死):intentionally
administering a lethal (致死的)drug to a terminally iii patient who has asked to be
relieved of suffering. Twenty times a day, life-prolonging treatment is withheld
or withdrawn when there is no hope that it can effect an ultimate cure. "Active"
euthanasia remains a crime on the Dutch statute books, punishable by 12 years in
prison. But a series of court cases over the past 15 years has made it clear
that a competent physician who carries it out will not be prosecuted.
Euthanasia, often called "mercy killing" is a crime everywhere in Western
Europe. But more and more doctors and nurses readily admit to practicing it,
most often in the "passive" form of withholding or withdrawing treatment. The
long simmering euthanasia issue has A. a doctor who practices euthanasia will not be punished B. euthanasia is regarded as illegal C. euthanasia is very popular D. active euthanasia is still illegal, but people often tolerate an experienced doctor who carries it out
