单选题{{B}}Passage 2{{/B}}
Nearly two thousand years have passed
since a census decreed by Caesar Augustus became part of the greatest story ever
told. Many things have changed in the intervening years. The hotel industry
worries more about overbuilding than overcrowding, and if they had to meet an
unexpected influx, few inns would have a manger to accommodate the weary guests.
Now it is the census taker that does the traveling in the fond hope that a
highly mobile population will stay put long enough to get a good sampling.
Methods of gathering, recording, and evaluating information have presumably been
improved a great deal. And where then it was the modest purpose of Rome to
obtain a simple head count as an adequate basis for levying taxes, now batteries
of complicated statistical series furnished by governmental agencies and private
organizations are eagerly scanned and interpreted by sages and seers to get a
clue to future events. The Bible does not tell us how the Roman census takers
made out, and as regards our more immediate concern, the reliability of present
day economic forecasting, there are considerable differences of opinion. They
were aired at the celebration of the 125th anniversary of the American
Statistical Association. There was the thought that business forecasting might
well be on its way from an art to a science, and some speakers talked about
newfangled computers and high-falutin mathematical systems in terms of
excitement and endearment which we, at least in our younger years when these
things mattered, would have associated more readily with the description of a
fair maiden. But others pointed to the deplorable record of highly esteemed
forecasts and forecasters with a batting average below that of the Mets, and the
President-elect of the Association' cautioned that "high powered statistical
methods are usually in order where the facts are crude and inadequate, the exact
contrary of what crude and inadequate statisticians assume". We left his
birthday party somewhere between hope and despair and with the conviction, not
really newly acquired, that proper statistical methods applied to ascertainable
facts have their merits in economic forecasting as long as neither forecaster
nor public is deluded into mistaking the delineation of probabilities and trends
for a prediction of certainties of mathematical
exactitude.

单选题Most people who travel long distances complain of jetlag (飞行时差反应). Jetlag makes business travelers less productive and more prone
21
making mistakes. It is actually caused by
22
of your "body clock"—a small cluster of brain cells that controls the timing of biological
23
. The body clock is designed for a
24
rhythm of daylight and darkness, so that it is thrown out of balance when it
25
daylight and darkness at the wrong times in a new time zone.
The
26
of jetlag often persist for days
27
the internal body clock slowly adjusts to the new time zone. Now a new anti-jetlag system is
28
that is based on proven
29
pioneering scientific research.
Dr. Martin Moore-Ede has
30
a practical strategy to adjust the body clock much sooner to the new time zone
31
controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates
32
of the discomfort of jetlag. A successful time zone shift depends on knowing the exact time to either
33
or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule
34
light exposure depends a great deal on
35
travel plans. Data on a specific flight itinerary (旅行路线) and the individual"s sleep
36
are used to produce a Trip Guide with
37
on exactly when to be exposed to bright light. When the Trip Guide calls
38
bright light, you should spend time outdoors if possible. If it is dark outside, or the weather is bad,
39
you are on an aeroplane, you can use a special light device to provide the necessary light
40
for a range of activities such as reading, watching TV or working.

单选题
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 Rico and Java.
Low average population densities are characteristic of most underdeveloped
countries. Low density of population is generally associated with a relatively
low percentage of cultivated land. This generally results from poor-quality
lands. It may also be due to natural obstacles to cultivation, such as deserts,
mountains or malaria-infested jungles, to land uses other than cultivation, as
pasture and forested land, to primitive methods that limit cultivation, to
social obstacles, and to land ownership systems which keep land out of
production. More economically advanced countries of low
population density have, as a rule, large proportions of their populations
living in urban areas. Their rural population densities are usually very low.
Poorer developed countries of correspondingly low general population density, on
the other hand, often have a concentration of rural population living on arable
land, which is as great as the rural concentration found in the most densely
populated industrial countries.
