资就会降下来。要排除这因素，另外一个版本是说那些没有大学学历的人的工资不会降低，如果降低的话，即便有大学学历的人的工资多了，但是还是不能判断总体工资升降。我记得还有一个第三个版本貌似是说那些增加的大学学历的人并不会因为人数的增加而导致找不到工作，因为找不到工作，工资肯定也不高。我好像还看过第４个版本，说什么随着科技的进步，那些原本需要大学学历的工作并不会因此而被那些没有大学学历的人所取代，因为那些没有大学学历的人便宜。总之好多变体，各位小心吧。

Early in the twentieth century, Lake Konfa became very polluted. Recently fish populations have recovered as release of industrial pollutants has declined and the lake’s waters have become cleaner. Fears are now being voiced that the planned construction of an oil pipeline across the lake’s bottom might revive pollution and cause the fish population to decline again. However, a technology for preventing leaks is being installed. Therefore, provided this technology is effective, the fears are groundless.
Which of the following, if true, most seriously weakens the argument?
A. The pipeline’s construction will disturb sediments at the bottom of the lake, dispersing into the water toxic pollutants that have settled there.
B. Changes in land use and drainage patterns around the lake mean that the lake’s waters are increasingly likely to be affected by agricultural runoff.
C. The leak-preventing technology has been in use for several years without any pipeline in which it is installed developing serious leaks.
D. A major leak of oil from the pipeline would harm not only the lake’s fish but also populations of other aquatic animals and plants.
E. Since the beginning of the twentieth century, non-native species of fish have been introduced into the lake and now make up a considerable proportion of its overall fish population.
K湖被污染，但是随着最近的排污减少，鱼类开始慢慢恢复。但是海底要建一个输油管，担心可能会漏油，再次造成污染，但是科技可以防止漏油，所以不用担心了。问削弱？ Ａ选项说输油管虽然不泄漏但是会搅乱已经沉淀在湖底的那些曾经的污染物又污染湖水

Which of the following most logically completes the passage?
A certain tropical island received food donations in the form of powdered milk for distribution to its poorest residents, who were thought to be malnourished. Subsequently, the rate of liver cancers among those islanders increased sharply. The donated milk was probably to blame: recent laboratory research on rats has shown that rats briefly exposed to the substance
aflatoxin tend to develop liver cancer when fed casein, a milk protein. This result is relevant because __________.
A. in the tropics, peanuts, a staple of these island residents, support a mold growth that produces aflatoxin
B. the liver is more sensitive to carcinogens, of which aflatoxin may be one, than most other bodily organs
C. casein is not the only protein contained in milk
D. powdered milk is the most appropriate form in which to send milk to a tropical destination E. the people who were given the donated milk had been screened for their ability to digest milk
热带地区的一个岛屿接受奶粉捐赠，然后分给那些最穷的人们。然后岛内居民的肝癌的发病率上升。可能是捐赠的奶粉的问题。因为科学家研究发现给老鼠吃这些奶粉，这些老鼠得了肝癌，因为黄曲霉素容易导致肝癌当给老鼠吃一种牛奶里的叫做Ｃ的蛋白质。问联系？Ａ选项说在热带人们经常吃花生，可以产生大量的黄曲霉素，从而和奶粉一起吃导致了肝癌的发生。

(GWD 28-Q17)
In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria’s roads but are involved in 12 percent of all highway fatalities. The very largest trucks—those with three trailers—had less than a third of the accident rate of single-and
double-trailer trucks. Clearly, therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks.
Which of the following, if true, most seriously weakens the argument?
A. Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only.
B. No matter what changes Partoria makes in the regulation of trucking, it will have to keep some smaller roads off-limits to all large trucks.
C. Very few fatal collisions involving trucks in Partoria are collisions between two trucks.
D. In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.
E. In Partoria, the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks.
在P地方大型卡车的事故率高于其他车型。但是那些有三个trailers的卡车比那些只有一个或者二个trailer的卡车事故率低。很显然，为了降低事故率，我们都要使用三个trailers的卡车。问削弱？Ａ说那些有三个ｔｒａｉｌｅｒｓ的汽车一般都用在车辆最少的公路上，所以撞车几率小。

Yeasts capable of leavening bread are widespread, and in the many centuries during which the ancient Egyptians made only unleavened bread, such yeasts must frequently have been mixed into bread doughs accidentally. The Egyptians, however, did not discover leavened bread until about 3000 B.C. That discovery roughly coincided with the introduction of a wheat variety that was preferable to previous varieties because its edible kernel could be removed from the husk without first toasting the grain.
Which of the following, if true, provides the strongest evidence that the two developments were causally related?
A. Even after the ancient Egyptians discovered leavened bread and the techniques for reliably producing it were well known, unleavened bread continued to be widely consumed.
B. Only when the Egyptians stopped the practice of toasting grain were their stone-lined grain-toasting pits available for baking bread.
C. Heating a wheat kernel destroys its gluten, a protein that must be present in order for yeast to leaven bread dough.
D. The new variety of wheat, which had a more delicate flavor because it was not toasted, was reserved for the consumption of high officials when it first began to be grown.
E. Because the husk of the new variety of wheat was more easily removed, flour made from it required less effort to produce.
酵母被用来发酵被广泛运用，酵母在很多世纪之前被古埃及人偶然发现。埃及人没有发明酵母知道３０００ＢＣ，这种发现大致和一种新的小麦一起出现，这种新小麦比之前的风味好，而且直接把外壳去掉得到里面的仁，而且不用烤。问前面提到的２个现象怎么联系在一起。C选项是说原来的品种要烤过之后才可以，破坏了蛋白质，所以没有办法发酵。也就是说现在这种新的不用破坏蛋白质所以可以发酵，也就在它们之间建立的因果

In Kravonia, the average salary for jobs requiring a college degree has always been higher than the average salary for jobs that do not require a degree. Over the last few years, the number of Kravonians enrolled in college has been growing steadily. Therefore, the number of
Kravonians entering the job market who have at least the qualification of a college degree will eventually be significantly higher than it has been over the last few years.
Which of the following, if true, most seriously weakens the argument?
A. Kravonians with more than one college degree earn little more, on average, than do Kravonians with only one college degree.
B. The average number of years Kravonian college students remain enrolled before completing a degree has been increasing over the past several years.
C. Despite the increase in the number of Kravonians attending college, the percentage of the population attending college is lower in Kravonia than in most other countries.
D. In recent years, employers have been requiring college degrees for workers in jobs that were previously performed successfully by Kravonians who did not have college degrees.
E. For many years, employers in Kravonia have had difficulty finding enough college graduates to fill the high-paying jobs that were available.
Ｋ地区的有大学学历的人的工资比没有的要高，过去一些年Ｋ地区的大学入学率增高。因此进入劳动市场的大学学历的人数将增多。问削弱？Ｂ选项说Ｋ地区大学的毕业年限也增加了，意思是说短时间之内这些人还进入不了劳动力市场。我个人觉得削弱的不好，还不如说总体的就业人数也相应的增加了，所以即便有大学学历的人增加了，也显得微不足道了。

Until now, only injectable vaccines against influenza have been available. Parents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated. A new influenza vaccine,
administered painlessly in a nasal spray, is effective for children. However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray.
Which of the following is an assumption on which the argument depends?
A. Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.
B. The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do. C. The injectable vaccine is affordable for all adults.
D. Adults do not contract influenza primarily from children who have influenza. E. The nasal spray vaccine is not effective when administered to adults.
只有注射用的防流感疫苗可以用来抵御流感，父母很勉强给孩子们注射，因为孩子们怕疼，但是大人们如果得流感会有很大的并发症，所以经常注射。一种新型的喷雾式疫苗出现了，可以给孩子们用。但是孩子们很少出现并发症，所以出现这种喷雾式疫苗并广泛应用的好处不大。问ｄｅｐｅｎｄｓ？ Ｄ选项说大人不会从孩子那里传染流感。意思是说如果大人可以从小孩那传染流感的话，所以给孩子们使用疫苗还是非常有意义的，要排除这种可能性。
