Part Ⅱ Reading Comprehension
Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.
Questions 21 to 25 are based on the following passage:
Solar energy for your home is coming. It can help you as a single home owner.It can help the whole country as well.Whether or not solar energy can save your
money depends on many things. Where you live is one factor. The type of home you
have is another. Things like insulation present energy coasts, and the type of
ssstem you buy are added factors.
Using solar energy can help save our precious fuel. As you know, our supplies
of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs.And when Mother Nature says that's all. The only way we ca
n delay hearing those words is by starting to save energy now and by using other
sources, like the sun.
We won't have to worry about the sun's running out of energy for another sev
eral billion years or so. Besides begin an endless sourse of energy, the use of the sun has other advantages as well. The sun doesn't offer as many problems as
other energy sources. For example, fossil fuel plants add to already high pollution
levels. With solar energy, we will still need sources of energy, but we won't need as much. That means we can cut down on our pollution problems.
With all these good points, why don't we use more solar power? There are many
reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy.
All that is changing now. Solar coats are starting to equal the costs of oil and electricity. Experts say that gas, oil and electricity prices will continue to
rise. The demand for electricity is increasing rapidly. But new power plants will
use more gas,oil or coal. Already in some places the supply of electricity is being
rationed. Solar energy is now in its infancy. It could soon grow to become a major part of our nation's energy supply.

 C) and the supply of electricity will be rationed
 D) but we don ' t need practice energy rationing now
Questions 26 to 30 are based on the following passage:
Nearly 54 million cars and trucks in the United States are equipped with driver side air bags located in the center of the steering wheel. 24 million also
have a passenger  side device located in the dashboard. Air bags are designed to protect against sudden, fierce frontal highway impacts.
Five years ago evidence of serious air  bag injuries began to surface. Drivers
in minor fender benders suffered severe eye and ear injuries, broken bones and
third  degree burns from the force of the inflating bags. In December 1991 the National Highway Traffic Safety Administration (NHTSA) advised parents to avoid putting rear  facing infant sets in front of air bags, acknowledging that the force
of the explosive bag could harm infants, whose heads were only inches away from the devices.
Last October it was determined that all children 12 and under were more susceptible to injury and death than adults; their more fragile bodies were seated lower, increasing the impact of the air bag to the head area. In addition, more children were not properly restrained or were out of position when the air bag inflated. On November 22, 1996, after nearly 60 deaths and thousands of injuries were attributed to the devices, the NHTSA mandated improved labels for all new vehicles, warning of the risk to children under 13. Despite these problems, officials stress the overall effectiveness of these devices. “All in all, air bags work well
and are responsible for an 11 percent reduction in driver fatalities,” says NHT
SA Administrator Dr. Ricardo Martinez.
“ First and foremost, make sure you're properly buckled up before getting on
the road,” says Brain O'Neill, president of the Insurance Institute for Highway Safety. Keep in mind how close you sit to an air bag. Push seats as far back as possible, remaining just close enough to control the pedals. Your face and torso should be at least ten to 12 inches from the steering column. “It's not a bad idea actually to measure the distance with a ruler to be sure.” adds O'Neill.
Adjustable steering wheels should be pointed toward the chest rather than the
head to prevent inflating bag from damaging the face or neck. Also, position hands at nine o'clock and three o'clock on the wheel to keep your arms away from an
opening air bag.
Pregnant women in particular should keep their abdomen as distant from the
air bag as possible. In the final trimester,women should point adjustable steering
wheels upward, away from their fetus.
Perhaps most important, children 12 and under should always ride in the back
seat, buckled up.
 26. From the passage, we learned that ____.
 A) there are 24 million cars and trucks in the United States
 B) there are 78 million cars and trucks in the United States
 C) there are 24 million cars and trucks equipped with air  bags in the United States
 D) there are 78 million cars and trucks equipped with air  bags in the United States
 27. The air bags are ____.
 A) safety devices which can protect people from being hurt during highway
accidents
 B) unsafe devices which hurt many people
 C) safety devices which saved 11% American drivers
 D) safety devices but need to be improved
 28. The air  bag is located in the center of the steering wheel,so you should ____.
 A) keep in mind how close you sit to an air bag
 B) push the front seat as far back as possible, remaining just close enough to control the pedal
 C) keep your face and torso at least 10 to 12 inches from the steering column
 D) all of the above
 29. Adjustable steering wheels should ____.
 A) be pointed toward the chest rather than the head
 B) be driven at 9 o ' clock
 C) be driven at 3 o ' clock
 D) keep your arms away from an opening air bag
 30. The air bag is a good safety device, but children 12 and under should always ride in the back seat buckled up means ____.
 A) air bags are no good for children
 B) air bags are only good for the parents who have more than 12 children
 C) the best position for children to ride a car is in the back seat and be buckled up
 D) the front seat is unsafe for young people
Questions 31 to 35 are based on the following passage:
In the debates about how a particular piece of land is to be used, the priorities often conflict. What should you do, for example, if you find out that under the fertile fields of a farming community there is a thick bed of coal which can
be strip mined? Strip mining rips up top soil and vegetation. But mining may create jobs, bring money to the town's businesses. Those who approve of strip mining say that the coal is needed, and they point out that it is quicker and cheaper to get coal from the surface than to go deep into the earth to get it by standard mining techniques. On the other hand, it takes nature 500 years to create an inch of top soil. As the countryside fills up, people are becoming more aware of the need for
open space. Nearly every proposal for a new power plant, highway, or airport dra
ws fierce opposition. Everyone wants the big, land  eating “ uglies ” to be in someone else ' s backyard. Minneapolis and St.Paul, Minnesota, for example, have been debating about the site of a future airport for years. Yet if a new airport is needed, it will have to go somewhere.
How do we find our way out of the land  used problem? One way might be to reexamine our values, to think in new directions. Does everyone have to have a car
with its need for highways and parking lots? What about developing mass transit systems that use less land? Do suburbs have to sprawl? Can they be designed so
they use less space? Do we have to have more energy? If we do, do we really have to strip  mine coal to provide it?
However difficult they may be to arrive at, choices will have to be made if
we want to preserve the beauty and usefulness of the land. For there is at least
one point on which all of us can agree: The land does have its limits.
31. The word “priorities” in the sentence means ____.
 A) the various needs
 B) the most important goal
 C) the number one necessity

 A) people are thinking to develop their living space into the sky
 B) people noticed the need for unoccupied land
 C) people are struggling to get more land from the space 
D) people are becoming more active on the space issue
 33. How do we find our way out of the land use problems?
 A) One way might be to reexamine our values, to think in new directions.
B) Everyone has to have a car with its need for highways and parking lots.
 C) We have to have more energy. We need strip  mine coal to provide it.
D) We may develop mass transit systems which use less land.
 34. “ Everyone wants the big, land eating ‘ uglies ' to be in someone else ' s backyard. ” shows that ____.
 A) people don ' t want more big projects
 B) people don ' t want to live in the neighborhood of the big projects

 C) Land and Our Life Styles
 D) Land and Space
Questions 36 to 40 are based on the following passage:
Television, or TV, the modern wonder of electronics, brings the world into your own home in sight and sound. The name television comes from the Greek word tele, meaning “far”,and the Latin word videre, meaning “to see”. Thus, television means“seeing far”. Sometimes television is referred to as video,from a Latin word
meaning “I see”. In Great Britain, the popular word for television is “telly”.
Television works in much the same way as radio. In radio, sound is changed in
to electromagnetic waves which are sent through the air. In TV, both sound and light are changed into electromagnetic waves. Experiments leading to modern television took place more than a hundred years ago. By the 1920s, inventors and researchers had turned the early theories into working models. Yet it took another thirty years for TV to become an industry.
As an industry, TV provides jobs for hundreds of thousands who make TV sets and broadcasting equipment. It also provides work for actors, technicians, and others who put on programs.
Many large schools and universities have “closed—circuit”television equipment that will telecast lectures and demonstrations to hundreds of students in different classrooms; and the lecture can be video taped to be kept for later use.Some hospitals use TV to allow medical students to get close  up view of operations. 
In 1946, after World War II, TV began to burst upon the American scene with
a speed unforeseen even by the most optimistic leaders of the industry. The novelty of seeing TV pictures in the home caught the public's fancy and began a revolution in the world of entertainment. By 1950, television had grown into a major part
of show business. Many film and stage stars began to perform on TV as television
audiences increased. Stations that once telecast for only a few hours a day sometimes telecast around the clock in the 1960s.
 36. “… others who put on programs. ” means that ____.
 A) people get on their clothes with programs printed on
 B) people prepare and present the programs on TV
 C) people like the programs
 D) people acted in the TV programs
 37. “… to allow medical students to get close  up view of operations ” suggests ____.
 A) the students can have view of operations with enlarged details
 B) the students can operate through TV
 C) the students were allowed to learn operations
 D) TV is being used by students
 38. “… TV began to burst upon the American, …” indicates that
____.
 A) in 1946 TV sets exploded in American families
 B) TV may injure people
 C) TV suddenly became available to many American families
 D) TV was very popular in 1946
 39. “ TV pictures in the home caught the public ' s fancy, …” tells
us ____.
 A) TV pictures are better than movies
 B) TV pictures can be seen at home
 C) TV pictures can hurt people ' s eyes
 D) TV pictures had aroused people ' s interests
 40. “… sometimes telecast around the clock in the 1960s. ” means
____.
 A) TV telecast used to have a round clock
 B) people watch TV with around clock nearby
 C) TV telecast 24 hours a day in the 1960s
 D) TV was on show everyday 
