Questions 21 to 25 are based on the following passage.
What might driving on an automated highway be like? The answer depends on
what kind of system is ultimately adopted. Two distinct types are on the
drawing board. The first is a specialpurpose lane system, in which certain
lanes are reserved for automated vehicles. The second is a mixed traffic system:
fully automated vehicles would share the road with partially automated or manual
driven cars. A specialpurpose lane system would require more extensive physical
modifications to existing highways, but it promises the greatest gains in
freeway(高速公路)capacity.
Under either scheme, the driver would specify the desired destination,
furnishing this information to a computer in the car at the beginning of the
trip or perhaps just before reaching the automated highway. If a mixed traffic
system way was in place, automated driving could begin whenever the driver was
on suitably equipped roads. If specialpurpose lanes were available, the car
could enter them and join existing traffic in two different ways. One method
would use a special onramp(入口引道).
As the driver approached the point of entry for the highway, devices
installed on the roadside would electronically check the vehicle to determine
its destination and to ascertain that it had the proper automation equipment in
good working order. Assuming it passed such tests, the driver would then be
guided through a gate and toward an automated lane. In this case, the transition
from manual to auto mated control would take place on the entrance ramp. An
alternative technique could employ conventional lanes, which would be shared by
automated and regular vehicles. The driver would steer onto the highway and move
in normal fashion to a "transition'lane. The vehicle would then shift under
computer control onto alane reserved for automated traffic. (The limitation of
these lanes to automated traffic would, presumably, be well respected, because
all trespassers(非法进入者) could be swiftly identified by authorities.)
Either approach to joining a lane of automated traffic would harmonize the
movement of newly entering vehicles with those already traveling. Automatic
control here should allow for smooth merging without the usual uncertainties and
potential for accidents. And once a vehicle had settled into autmated travel,
the driverwould be free to release the wheel, open the morning paper or just
relax.

highways ________.
A) are being planned

22. A specialpurpose lane system is probably advantageous in that
________.
A) it would require only minor changes to existing highways

23. Which of the following is true about driving on an automated
highway?
A) Vehicles traveling on it are assigned different lanes according to
their
destinations.
B) A car can join existing traffic any time in a mixed lane system.
C)The driver should inform his car computer of his destination before
driving onto
it.
D) The driver should share the automated lane with those of regular
vehicles.
24. We know from the passage that a car can enter a specialpurpose
lane________.
A) by smoothly merging with cars on the conventional lane
B) by way of a ramp with electronic control devices
C) through a specially guarded gate
D) after all trespassers are identified and removed
25. When driving in an automated lane, the driver ________.
A) should harmonize with newly entering cars
B) doesn't have to rely on his computer system
C) should watch out for potential accidents
D) doesn't have to hold on to the steering wheel
Passage Four
Questions 26 to 30 are based on the following passage.
Taking charge of yourself involves putting to rest some very prevalent
myths. At the top of the list is the notion that intelligence is measured by
your ability to solve complex problems; to read, write and compute at certain
levels;and to resolve abstract equations quickly. This vision of intelligence
asserts formal education and bookish excellence as the true measures of
selffulfillment. It encourages a kind of intellectual prejudice that has
brought with it some discouraging results. We have come to believe that someone
who has more educational merit badges, who is very good at some form of school
discipline is"intelligent." Yet mental hospitals are filled with patients who
have all of the properly lettered certificates. A truer indicator of
intelligence is an effective, happy life lived each day and each present moment
of every day.
If you are happy, if you live each moment for everything it's worth, then
you are an intelligent person. Problem solving is a useful help to your
happiness, but if you know that given your inability to resolve a particular
concern you can still choose happiness for yourself, or at a minimum refuse to
choose unhappiness, then you are intelligent. You are intelligent because you
have the ultimate weapon against the big N. B. D. --Nervous Break Down.
"Intelligent'people do not have N.B.D.'s because they are in charge of
themselves. They know how to choose happiness over depression, because they know
how to deal with the problems of their lives.
You can begin to think of yourselfas truly intelligent on the basis of how
you choose to feel in the face of trying circumstances. The life struggles are
pretty much the same for each of us. Every one who is involved with other
humanbeings in any social context has similar difficulties. Disagreements,
conflictsand compromises are a part of what it means to be human. Similarly,
money, growing old,sickness, deaths, natural disasters and accidents are all
events which present problems to virtually all human beings. But some people are
able to make it, to avoid immobilizing depression and unhappiness despite such
occurrences, while others collapse or have an N. B.D. Those who recognize
problems as a human condition and don' t measure happiness by an absence of
problems are the most intelligent kind of humans we know; also, the most
rare.
26. According to the author, the conventional notion of intelligence
measured in terms
of one' s ability to read, write and compute ________.
A) is a widely held but wrong concept
B) will help eliminate intellectual prejudice
C) is the root of all mental distress
D) will contribute to one's selffulfillment
27. It is implied in the passage that holding a university degree
________.
A) may result in one's inability to solve complex reallife problems
B) does not indicate one's ability to write properly worded documents
C) may make one mentally sick and physically weak
D) does not mean that one is highly intelligent
28. The author thinks that an intelligent person knows ________.
A) how to put up with some very prevalent myths
B) how to find the best way to achieve success in tire
C) how to avoid depression and make his life worthwhile
D) how to persuade others to compromise
29. In the last paragraph, the author tells us that ________.
A) difficulties are but part of everyone's life
B) depression and unhappiness are unavoidable in life
C) everybody should learn to avoid trying circumstances
D) good feelings can contribute to eventual academic excellence
30. According to the passage, what kind of people are rare?
A) Those who don't emphasize bookish excellence in their pursuit of
happiness.

from N.
B. D. ' s.
D) Those who are able to secure happiness though having to struggle against
trying
