Priscilla Ouchida’s house turned out to be a horrible dream .When she
and her engineer husband married a few years ago ,they built a $100,000
,three-bedroom home in California.Tightly sealed to prevent air leaks,the house
was equipped with small double-paned(双层玻璃的) widows and several other energy –saving qualities .Problems began
as soon as the couple moved in,however.Priscilla”s eyes burned .Her throat was
often dry .She suffered from headaches and could hardly sleep .It was as though
she had suddenly developed a strange illness.
Experts finally found the cause of her illness.The level of formaldehyde(甲醛) gas in her kitchen was twice
the largest amount allowed by
federal standards for chemical workers .The source of the gas? Her new
kitchen cabinets and wall-to –wall
carpeting.
The Ouchidas suffered the effects of indoors air pollution,which is not
given enough attention partly because of the nation’s drive to save energy .The
problem itself isn’t new . “The
indoor environment was dirty long before energy saving came along ,”says
Moschandreas,a pollution scientist at Geomet Technologies in Maryland .”Energy saving had worsened the
situation in some cases.”
The problem appears to be more troublesome in newly constructed homes
rather than old ones.Back in the days when energy was cheap ,home builders
didn’t worry much about unsealed cracks(裂缝).Because of such leaks,the air in an average home was replaced by
fresh outdoor air about once an hour .As a result ,the pollutants caused by
most households seldom built up to dangerous levels.
62.It can be learned from the passage that the Ouchidas’ house______.
A. is well worth the money spent on its construction
B. is almost faultless from the point of energy saving
C. failed to meet energy saving standards
D. was designed and constructed in a scientific way
63.What made the Ouchidas’ new house a horrible dream?
A. Lack of fresh air
B. Poor quality of building materials
C. Gas leakage in the kitchen
D. The newly painted walls
64.Why didn’t people care about cracks in the past?
A.
Because indoor cleanness was
not emphasized
B.
Because energy used to be
inexpensive
C.
Because environmental
protection was not taken into consideration
D.
Because they had to build their
houses in that way
65.This passage is most probably taken from an article with the title
“______”
A.
Energy saving B.House building
B.
Air Pollution Indoor D.Traps in
buildingConstruction

Long after the 1998 World Cup was
won,disappointed fans were still questioning the refereeing on their decisions
that denied victory to their team.A researcher was aked to study the
performance of some top referees.
The researcher organized an
experimental tournament involving four youth teams.Each match lasted an hour
,divided into three periods of 20 minutes ,during which different referees were
in charge.
Observers noted down the rederees’ errors,verted to a standard match of 90 minutes ,each referee made
almost 23 mistakes ,a very high number.
The researcher then studied the videotapes
to study the matches carefully .Surprisingly ,he found that errors were more
likely when the referees were close to the incident .When the officials got it right ,they were ,on average ,17
meters away from the action .The average distance in the case of error was 12
meters .The research shows the optimum distance is about 20 meters.
There also seemed to be an optimum speed .Correct decisions came when
the referees were moving at a speed of about 2 meters per second .The average
speed for errors was 4 meters per second..
If FIFA,football’s international ruling body ,wants to improve the
standard of referees at the next World Cup,it should encourage referees to keep
their eyes on the action from a distance,rather than rushing to keep up with
the ball ,the researcher argues.
He also says that FIFA’s insistence that referees should retire at age
45 may be misguided.If keeping up with the action is not so important ,their
physical condition is less important.
66.The experiment done by the researcher was meant to ______
A.
review the decisions of
referees at the 1988World Cup.
B.
Find out the cause of errors
made by football referees.
C.
Set a standard for football
refereeing
D.
Re-examine the rules for
football refereeing
67.The number of refereeing errors in the experimental matches was ____
A.
slightly above average
B.
higher than in the 1988 World
Cup
C.
quite unexpected
D.
as high as in a standard match
68.The findings of the experiment show that ______.
A.
errors are more likely when a
referee keeps close to the ball
B.
The farther the referee is from
the incident,the fewer the errors
C.
The more slowly the referee
runs ,the more likely errors will occur
D.
Errors are less likely when a
referee stays in one spot
69.The word “ officials” (Para .4) most probably refers to _____
A.the researchers involved
in the experiment
B.the inspectors
of the football tournament
C.
the referees of the football
tournament
D.
the observers at the site of
the experiment
70.What is one of the possible conclusions
of the experiment?
A.
the ideal retirement age for an
experienced football referee is 45
B.
Age should not be the chief
consideration in choosing a football referee.
C.
A football referee should be as
young and energetic as possible
D.
An experienced football referee
can do well even when in poor physical condition.
