问题一:
One advantage of breeding African bees with other
bee types (Africanization) may be resistance to the para-
sitic mite Varroa jacobsoni, a major threat to modern
Line beekeeping. In parts of Europe, this mite is devastating
5 honeybees and killing many colonies despite preventive
measures by beekeepers. But in Brazil Varroa jacobsoni
has been present in Africanized bees since 1972 without
the loss of a single colony, even though beekeepers there
undertook no preventive measures. The mites lay eggs
10 within the brood cells of immature bees, and developing
mites feed on the hemolymph (blood) of bee pupae. But
fewer mites reproduce in Africanized bees than in
European bees. Some researchers point out that this
resistance may be related to the Africanized worker bee's
15 shorter development period, which prevents some mites
from reaching maturity. Recently the mite has become a
serious problem in colonies of European bees in North
America. Africanization of these bees may be the best
safeguard against this parasite.

The author's argument regarding the resistance of
Africanized bees to Varroa jacobsoni would be
most weakened if which of the following were true?
○A The bees in Brazil were resistant before being
Africanized.
○B The number of bee colonies in North American
increased dramatically whereas the number in
Brazil remained unchanged.
○C Mites found in European bees reproduce at a
faster rate than mites of identical species
found in the bees in Brazil.
○D Africanized bees retain many of the characteris-
tics of European bees.
○E Bee colonies in Europe continue to produce
greater quantities of honey than do those in
Brazil

问题2:
When a molten metal or metallic alloy is cooled to a
solid, a crystalline structure is formed that depends on the
particular alloy composition. In contrast, molten
Line nonmetallic glass-forming materials, when cooled, do not
5
assume a crystalline structure, but instead retain a
structure somewhat like that of the liquid--an amorphous
structure. At room temperature, the natural long-term
tendency for both types of materials is to assume the
crystalline structure. The difference between the two is in
10 the kinetics or rate of formation of the crystalline
structure, which is controlled by factors such as the nature
of the chemical bonding and the ease with which atoms
move relative to each other. Thus, in metals, the kinetics
favors rapid formation of a crystal line structure, whereas
15 in nonmetallic glasses the rate of formation is so slow that
almost any cooling rate is sufficient to result in an
amorphous structure.

The author implies that the rate at which the molten
materials discussed in the passage are cooled is a
determinant of the
(A) chemical composition of the resulting solids
(B) strength of the chemical bonds that are formed
(C) kinetics of the materials' crystalline structure
(D) structure the materials assume
(E) stability of the materials' crystalline structure

问题三:
Recent scholarship has strongly suggested that the aspects
of early New England culture that seem to have been most
distinctly Puritan, such as the strong religious orientation and
the communal impulse, were not typical of New England as a
whole, but were largely confined to the two colonies of
Massachusetts and Connecticut. Thus, what in contrast to the
Puritan colonies appears to Professor Davis to be peculiarly
Southern was not only more typically English than the
cultural patterns exhibited by Puritan Massachusetts and
Connecticut, but also almost certainly characteristic of most
other early modern British colonies from Barbados north to
Rhode Island and New Hampshire. Within the larger
framework of American colonial life, then, not the Southern
but the Puritan colonies appear to have been distinctive, and
even they seem to have been rapidly assimilating to the
dominant cultural patterns by the late Colonial period.

Which of the following statements could most logically
follow the last sentence of the passage?
(A) Thus, had more attention been paid to the
evidence, Davis would not have been tempted
to argue that the culture of the South
diverged greatly from Puritan culture in the
seventeenth century.
(B) Thus, convergence, not divergence, seems to
have characterized the cultural development
of the American colonies in the eighteenth
century.
(C) Thus, without the cultural diversity represented
by the America South, the culture of colonial
America would certainly have been
homogeneous in nature.
(D) Thus, the contribution of Southern colonials to
American culture was certainly overshadowed
by that of the Puritans.
(E) Thus, the culture of America during the Colonial
period was far more sensitive to outside
influences than historians are accustomed to
acknowledge.这道题为什么不选A呢?文章不是说the culture of sounthern 更接近与英国文化,而Puritan colonies distincitive了吗,distinctive 不就是different吗。然后我就理解了英语puritan colonies融入了当地文化,与英国文化越来越远,被当地文化通化了,请问哪里错了啊?

还有想请教大家一下逻辑题应该怎么去思考啊。我是文科生,从来就没有在逻辑推导方面有接触,再加上自己本身也不擅长逻辑推论,真是要着急哭了……请问大家应该怎么办啊?

第一题:因为是weaken题,要找到作者的推论过程再进行削弱。
全文在推广Africanized bee的好处,从“But in Brazil Varroa jacobsoni
has been present in Africanized bees since 1972 without
the loss of a single colony, even though beekeepers there
undertook no preventive measures.”这个转折句可知,欧洲蜜蜂没有Africanize,所以被VJ弄得很惨,但是巴西蜜蜂自1972年开始Africanize,所以没被VJ影响。那么作者的逻辑就是:Africanize这个原因导致蜜蜂对VJ免疫。
现在要对“The author's argument regarding the resistance of
Africanized bees to Varroa jacobsoni”进行削弱,根据作者逻辑,是Africanize导致的Africanized bees对VJ免疫,那么A选项指出在Africanize之前蜜蜂就已经免疫了就指出了这个结论是由其他原因导致的,从而否定了作者逻辑的前提,这就很好地weaken了作者推论。

lz可以看看附件里这个文档,是分析GMAT逻辑题的,很有用,我当时看完了觉得豁然开朗。GRE的逻辑题和GMAT基本差不多,而且要求还低一点。希望有帮助~
