Authorities in California required drivers to use their
headlights on a certain road during the daytime as well
as at night and found that annual accident rates on the
road fell 15 percent from the previous level. They
concluded that applying the daytime rule statewide
would lead to a similar reduction in accidents.
Which of the following, if true, most strengthens the
authorities' argument?
(A) Because an alternate route became available, the
volume of traffic on the test road decreased during
the test period.
(B) Drivers were informed of the requirement to use
their headlights on the test road by means of a
series of three conspicuous signs in each direction
of travel.
(C) Under certain conditions, among them fog and
heavy rain, most drivers in California already use
their headlights during the daytime.
(D) Full-scale application of the daytime rule would
cause headlight bulbs to burn out sooner than
they currently do and thus to require more
frequent replacement.
(E) The test road was selected to include a great
variety of the sorts of road conditions that drivers
in California are likely to encounter.
答案是A,我选E

Isadora Duncan's masterly writings on the dance reveal
the depth of her determination to create a lyric form of the art
which was free of characterization, storytelling, and the
theatrical exhibition of skills. She wished to discard the
traditional methods and established vocabularies of such dance
forms as ballet and to explore the internal sources of human
expressiveness. She shunned bodily ornamentation and
strove to use only the natural movements of her body,
undistorted by acrobatic exaggeration and stimulated only by
internal compulsion. In her recitals Duncan danced to the music
of Beethoven, Wagner, and Gluck, among others, but,
contrary to popular belief, she made no attempt to visualize or
to interpret the music; rather, she simply relied on it to provide
the inspiration for expressing inner feelings through movement.
Select the sentence in the passage that implies the
argumentative function which the author mentions
Duncan‘s reliance on music in her recitals to serve.
答案是:She shunned bodily ornamentation……
我觉得它前面一句和后面一句也都可以的样子。。

Which of the following, if true, most logically
completes the passage?
Every fusion reaction releases neutrinos. To test a
hypothesis about the frequency of fusion reactions in the
Sun, physicists calculated the number of neutrinos the
Sun would produce annually if the hypothesis were
correct. From this they estimated how many neutrinos
should pass through a particular location on Earth. The
fact that far fewer neutrinos were counted than were
predicted to pass through the location would seem to
prove that the hypothesis is wrong, except that------.
(A) the physicists, using a different method for
estimating how many neutrinos should reach the
location, confirmed their original estimate
(B) there are several competing hypotheses about the
frequency of solar fusion reactions
(C) there is not enough energy in the Sun to destroy a
neutrino once it is released
(D) the method used to count neutrinos detects no
more than approximately ten percent of the
neutrinos that pass through
(E) neutrinos released in the fusion reactions of other
stars also reach the Earth
答案是E,我选D

Experiments show that insects can function as pollinators
of cycads, rare, palmlike tropical plants. Furthermore,
cycads removed from their native habitats—and therefore
from insects native to those habitats—are usually infertile.
Nevertheless, anecdotal reports of wind pollination in
cycads cannot be ignored. The structure of cycads male
cones is quite consistent with the wind dispersal of pollen,
clouds of which are released from some of the larger cones.
The male cone of Cycas circinalis, for example, sheds
almost 100 cubic centimeters of pollen, most of which is
probably dispersed by wind. Furthermore, the structure of
most female cycad cones seems inconsistent with direct
pollination by wind. Only in the Cycas genus are the
females' ovules accessible to airborne pollen, since only in
this genus are the ovules surrounded by a loose aggregation
of megasporophylls rather than by a tight cone.
The passage suggests that which of the following is
true of the structure of cycad cones?
A The structure of cycad cones provides conclusive
evidence in favor of one particular explanation
of cycad pollination.
B The structure of male cycad cones rules out a
possible mechanism for cycad pollination that is
suggested by the structure of most female cycad
cones.
C The structure of male cycad cones is consistent
with a certain means of cycad pollination, but
that means is inconsistent with the structure of
most female cycad cones.
答案是C,我选了AC,因为这篇文章不是in favor of insect传授花粉了吗?
求指点,多谢!! |
