Spread across the United States are about 500,000 doctors, cheeked by jowl, in the 'Jl3%axR

of America’s 500,000 doctors should be candidates for disciplinary action, many of apv"s+

Questions 26 to 30 are based on the following passage. <>|/U `
Bacteria are extremely small living things. While we measure our own sizes in E3<~C(APW
inches or centimeters, bacterial size is measured in microns. O ne micron is a =
hse2f
thousandth of a millimeter: a pinhead is about a millimeter across. Rod-shaped H(k-jAO,
bacteria are usually from two to four microns long, while rounded ones are generally 7o5~J)qIC
one micron in diameter. Thus, if you enlarged a rounded bacterium a thousand times, Ko|p&-Z;
it would be just about the size of a pinhead. An adult human magnified by the same Gv uX"J
amount would be over a mile (1.6 kilometers) tall. 4|[)D/N
Even with an ordinal microscopy, you must look closely to see bacteria. Using a v<wR`7xG
magnification of 100 times, one finds that bacteria are barely visible as tiny rods or V)g{ Ew]:
dots. One cannot make out anything of their structure. Using special stains, one can K!a4
>Du{
see that some bacteria have attached to them wavy-looking “hairs” called flagella. `zZGL&9m`
Others have only one flagellum. The flagella rotate, pushing the bacteria through the 'E#;`}&Ah
water. Many bacteria lack flagella and cannot move about by their own power, while ",&c"r4c
others can glide along over surfaces by some little-understood mechanism. -<GSHckD
From the bacterial point of view, the world is a very different place from what it is 1FQ_`wF4
to humans. To a bacterium, water is as thick as molasses is to us. Bacteria are so small g Q@fe3[
that they are influenced by the movements of the chemical molecules around them. iig ({b
Bacteria under the microscope, even those with no flagella, often bounce about in 3S_H hvB
the water. This is because they collide with the water molecules and are pushed this OY>0qj
way and that. Molecules move so rapidly that within a tenth of a second the molecules UPI'O %
around a bacterium have all been replaced by new ones; even bacteria without flagella }*ZOD1j
are thus constantly exposed to a changing environment. y$n`+%_

Questions 31 to 35 are based on the following passage. n;eK2+}]
Although, recent years have seen substantial reductions in noxious pollutants from Q0}Sju+HX
individual motor vehicles, the number of such vehicles has been steadily increasing. wd/"! A4(
Consequently, more than 100 cities in the United States still have levels of carbon UqP
%S$9
monoxide, particulate matter, and ozone (generated by photochemical, reactions with !/6`<eQ
`
hydrocarbons from vehicle exhaust) that exceed legally established limits. There is a dz6i~&
growing, realization that the only effective way to achieve, further reductions in \*5_gPj!d
vehicle emissions-short of a massive shift away from the private automobile-is to vPV=K+1
replace conventional diesel fuel and gasoline with cleaner burning fuels such as },2mIit(
compressed natural gas liquefied petroleum gas, ethanol, or methanol. Ier0F7]I
All of these alternatives are carbon-based fuels whose molecules are smaller and 4;*o}E
simpler than those of gasoline. These molecules burn more cleanly than gasoline, in R9/(z\'}
part because they have fewer, if and, carbon-carbon bonds, and the hydrocarbons they .[Z<r>
do emit are less likely to generate ozone. The combustion of large molecules, which X\I"%6$
have multiple carbon-carbon bonds, involves a more complex series of reactions. bGl5=`
These reactions increase the probability of incomplete combustion and are more likely @y (9LSs
to release uncombusted and photochemically active hydrocarbon compounds into the v\Y362Xv
atmosphere. O n the other hand, alternative fuels do have drawbacks. Compressed gCMwmanX
natural gas would require that vehicles have a set of heavy fuel tanks-a serious &J\V
!uVo
liability in terms of performance and fuel efficiency and liquefied petroleum gas faces )1KlcF
fundamental limits on supply. TZT1nj"n
Ethanol and methanol, on the other hand, have important advantages over other ;t.LLd
carbon-based alternative fuels; they have hither energy content per volume and would =]pcC
require minimal changes in the existing network for distributing motor fuel. Ethanol is .,C8ASfh
commonly used as a gasoline supplement, but it is currently about twice as expensive 9`/\|t|V
as methanol, the low cost of which is one of its attractive features. Methanol’s most m17H#!`
attractive feature, however, is that it can reduce by about 90 percent the vehicle
6wzTX8
emissions that form ozone, the most serious urban air pollutant. 6$}hb|j
Like any alternative fuel, methanol has its critics. Yet much of the criticism is /
$ 7_*4e
based on the use of “gasoline clone” vehicles that do not incorporate even the simplest ?lh
`>v
design improvements that are made possible with the use of methanol. It is true, for vwZrvjP2
example, that a given volume of methanol provides only about one-half of the energy pU4B6KTW
that gasoline and diesel fuel do; other things being equal, the fuel tank would have to YQzs0t ,
be somewhat larger and heavier. However, since methanol-fueled vehicles could be H!y%Fa Ti
designed to be much more efficient than “gasoline clone” vehicles fueled with 3[RbVT
methanol, they would need comparatively less fuel. Vehicles incorporating only the j5*W[M9W
simplest of the Engine improvements that methanol makes feasible would still TS
Q/{=r
contribute to an immediate lessening of urban air pollution. 0ciPH:V
31. The author of the passage is primarily concerned with __________. {2`:7U~|
A. countering a flawed argument that dismisses a possible solution to a problem. nVqFCBB
B. reconciling contradictory points of view about the nature of a problem. J?\z{ ;qa
C. identifying the strengths of possible solutions to a problem. `%lgT+~T
D. discussing a problem and arguing in favor of one solution to it. #>m#i1Nu
32. According to the passage, incomplete combustion is more likely to occur with (UDR=7w)
gasoline than with an alternative fuel because: __________. #`tn:cP
A. the combustion of gasoline releases photochemically active hydrocarbons. wl1JKiodg
B. the combustion of gasoline involves an intricate series of reactions. V9:h4]
C. gasoline molecules have a simple molecular structure. Sri,sZv
D. gasoline is composed of small molecules. ?QGAiu0

A. Further attempts to reduce emissions from gasoline-fueled vehicles will not |fXwH> 'sw
help lower urban air-pollution levels. Is~bA_-

Z~}=q
methanol? 30 VvZb
A. It is substantially less expensive than ethanol. &DdFK.lt
B. It could be provided to consumers through the existing motor fuel distribution

Questions 36 to 40 are based on the following passage. Q7O8']~n
Tests of reaction times seemed to back up the notion that the two hemispheres Pb$ep|`u
differed in their processing styles. Researchers used to believe that an image goes to JF]HkH_u
one hemisphere first, and then to the opposite side of the brain. If the nature of the pX
]K-
stimulus and the preference of the hemisphere match up, then the person can respond =/MAKi}g
slightly more quickly and accurately in identifying the local or global image. kQXtO)
Still more startling, researchers found that the same appeared to hold for the brains ,mH2S/<}S
of chimps and perhaps other primates. The assumption has always been that HqXaT6#/
handedness and brain asymmetry are strictly human traits---part of the great brain ~JY
<DW7
reorganization that allowed our ancestor to use tools, speak and perhaps even think C.
dN)?O
rationally. But handedness is now widely claimed for primates and even birds, HXF5fs
amphibians and whales. And in the past few years, some psychologists have tested j;eR9jI$T
chimps and baboons and suggested their two hemispheres also differ in processing $aTZC>R
style. \MM(w&
Now researchers have come to see the distinction between the two hemispheres as O G#By6O
a subtle one of processing style, with every mental faculty shared across the brain, and zRsG
$)B
each side contributing in a complementary, not exclusive, fashion. A smart brain ?g2Wu0<
became one that simultaneously grasped both the foreground and the background of FCU~*c8Cs
the moment ;1K[N
0xE
The next problem was to work out exactly how the brain manages to produce Qy |*[
these two contrasting styles. Many researchers originally looked for the explanation in :i+Tf~k{
a simple wiring difference within the brain. This theory held that neurons in the left rz0~W6 U
cortex might make sparse, short-range connections with their neighbors, while cells 2w93 ~j
on the other side would be more richly and widely connected The result would be that G&MI@Hq
the representation of sensations and memories would be confined lo smallish, discrete z>+@pj
areas in the left hemisphere, while exactly the same input to a corresponding area of bY7d
the right side would form a sprawling even impressionistic pattern of activity. e"P>b? OY
Supporters of this idea argued that these structural differences would explain why RVtb0FL
left brain language areas are so good at precise representation of words and word C0;c'4(
sequences while the right brain seems to supply a wider sense of context and meaning. SUxz &xH
A striking finding from some people who suffer right-brain stokes is that they can GQO}E@W6C
understand the literal meaning of sentences-their l eft brain can still decode the Ul7)CT2:
words-- -but they can no longer get jokes or allusions. Asked to explain even a W\gu"g`u
common proverb, such as “a stitch in time saves nine”, they can only say it must have <)+9PV<w

Questions 41 to 45 are based on the following passage. 0w[#`
(此文不全) $/sIdFZi
The Du Pont Company, the 13th largest employer in the U.S., routinely gives =z`GC1]bL
pre-employment blood tests to all blacks who apply for jobs to determine who might Tov !X8p
be a carrier of the trait for sickle-cell anemia, even though the trait is regarded as k4Ed 7T-
largely harmless. Although there are other genetically transmitted blood diseases and DY| s|:d
metabolic disorders that predominate in racial or ethnic groups, blacks are the only !0Hx1I<*x
ones to be identified with a disease and examined for it at Du Pont. In a three month 5{?J5
study of genetic screening in the American lace, the New York Times found no vU(2[
other instance of an ethnic or racial group singled out in or company. $< &N#
Du Pont officials emphasize that the sickle trait tests do not represent discrimination P:,@2el
and are only an effort to help them avoid potentially harmful exposure to certain zi M~V'
chemicals. Yet the officials can offer no firm evidence that the trait -- not the disease, fHK`u'
but only a single abnormal gene -- makes blacks more vulnerable. @T>\pP]o
Du Pont, which employs well over 100,000 workers, is in the vanguard of American -'ff0l
companies doing genetic screening and thus is at the center of the debate over this tB-0wD=PR
area of science, debate so intense, so broad, that even medical directors from other }',/~T6
companies who believe possibilities of genetic screening want no part of it. At Ei@w*.3P<
least, not now but officials at Du a leader in the chemical industry with annual j?a^fcXB
gross sales of more than $ 10 billion, feel they have the money and the scientists to };{V]f 0
turn the distrust into achievement. If some chemicals are highly toxic and the [Aqy%mbG
workplace is less than pure, company officials reason, it is only logical to try to $H}G'LqiG
determine why some workers get sicker faster and why others seem to have more xLID@9Hbu
tolerance for industrial poisons. And so the company is looking beyond the skills and >/W
loyalty of its workers to ery genetic structure. {,V .IDs8[
The sickle-cell trait is not the same as sickle-cell anemia. The anemia is rare but :x85:pa
debilitating disorder found in fewer than 50,000 American blacks, about two-tenths of > J4Tk1//b
