真的好痛苦……今天错了好多……还有你们是怎么做到30S-50S一题的……
【精练】
1. Human beings have cognitive faculties that are
superior to those of other animals, and once humans
become aware of these, they cannot be made happy
by anything that does not involve gratification of
these faculties.
Which one of the following statements, if true, most
calls into question the view above?
———Bible Weaken Question Problem Set NO.1
逻辑链：人类比动物优在有感知能力——当他发现了他有这个能力——他就不会感到高兴如果不涉及到令他们满意的这个faculities
问削弱
思路：就找即使没有faculities他也不会不高兴。
Certain animals—dolphins and chimpanzees,
for example—appear to be capable of
rational communication.——扯到动物，排除
(B) Many people familiar both with intellectual
stimulation and with physical pleasures
enjoy the latter more.——intellectual stimulation和faculities异曲同工，身体和感知能力有点属于精神和肉体的关系，人们更喜欢后者，削弱命题。
(C) Someone who never experienced classical
music as a child will usually prefer popular
music as an adult.——这个如果用到F上来，只能解释如果一个人没有意识到国F，他会更喜欢B。而题目中是，他意识到了F，那么没有F他就不高兴。不一样。
(D) Many people who are serious athletes consider
themselves to be happy.——运动员认为他们很开心……是我打开方式不对？
(E) Many people who are serious athletes love
gourmet food.——这两个选项没看懂，我pass了
【逻辑链】

Traces of cultivated emmer wheat have been found among the earliest agricultural remains of many archaeological sites in Europe and Asia.The only place where the wild form of emmer wheat has been found growing is a relatively narrow strip of southwest Asia.Since the oldest remains of cultivated emmer wheat yet found are from village sites in the same narrow strip, it is clear that emmer wheat was first domesticated somewhere in that strip.
Which of the following, if true, most strengthens the argument?
逻辑链：野生EW只在SA的一个地方被发现过，因为最古老的人工培育EW也在同样的地方发现过——所以EW是在那个地方被培育出来的
问加强
思路：一切可能改变的因素都不存在，看选项吧其实我也不知道
The presentday distribution of another wild wheat, einkorn, which was also domesticated early in the development of agriculture, covers a much larger area of southwest Asia.削弱
(B) Modern experiments show that wild emmer wheat can easily be domesticated so as to yield nearly as well as traditionally domestic strains.提到可以被轻易繁殖——削弱
(C) At the time when emmer wheat was first cultivated, it was the most nutritious of all the varieties of grain that were then cultivated.——一个小麦的属性，无关
(D) In the region containing the strip where wild emmer wheat has been found, climatic conditions have changed very little since before the development of agriculture.算是加强吧——好牵强
(E) It is very difficult, without genetic testing, to differentiate the wild form of emmer wheat from a closely related wild wheat that also grows in southwest Asia.——削弱
57S
In the late 1980s, the population of sea otters in the North Pacific began to decline.There are two plausible explanations for the decline:predation, possibly by killer whales, or disease.Of these two, disease is the more likely, since a concurrent sharp decline in populations of seals and sea lions is believed to have been caused by disease, and diseases that infect these creatures are likely to be able to infect sea otters also.Which of the following, if true, most seriously weakens the reasoning?
逻辑链：海豹数量下降——因为病或者被捕食——因为病的比较可能因为同地区的海象啥的都得病了
问削弱：找出质疑，也就是相关于被捕的几率大
Killer whales in the North Pacific usually prey on seals and sea lions but will, when this food source is scarce, seek out other prey.——bingo！因为虎鲸没有海象次了，只能次海豹
(B) There is no indication that the sea otter population at any North Pacific location declined in the 1980s because of substantial numbers of sea otters migrating to other locations.——无关啊
(C) Along the Pacific coast of North America in the 1980s, sea otters were absent from many locations where they had been relatively common in former times.——栖息地比较，无关
(D) Following the decline in the population of the sea otters, there was an increase in the population of sea urchins, which are sea otters' main food source.——无关
(E) The North Pacific populations of seals and sea lions cover a wider geographic area than does the population of sea otters.——无关，都是在说属性而不是影响因素
23.1.57S
From 1978 to 1988, beverage containers accounted for a steadily decreasing percentage of the total weight of household garbage in the United States.The increasingly widespread practice of recycling aluminum and glass was responsible for most of this decline.However, although aluminum recycling was more widely practiced in this period than glass recycling, it was found that the weight of glass bottles in household garbage declined by a greater percentage than the weight of aluminum cans.Which of the following, if true of the United States in the period 1978 to 1988, most helps to account for the finding?
逻辑链：饮料罐重量总数下降因为回收——铝罐比玻璃的回收使用率高——但是玻璃在垃圾中的比率小了
问原因：没有告诉总重量，比率小了只可能从来推测是玻璃制品少了，找出改变玻璃制品的因素
Glass bottles are significantly heavier than aluminum cans of comparable size.——基数不知道，排除
(B) Recycled aluminum cans were almost all beverage containers, but a significant fraction of the recycled glass bottles had contained products other than beverages.——只能说明玻璃瓶重了啊
(C) Manufacturers replaced many glass bottles, but few aluminum cans, with plastic containers.——bingo！因为很多玻璃瓶都被换成塑料的了
(D) The total weight of glass bottles purchased by households increased at a slightly faster rate than the total weight of aluminum cans.——和增长速率无关
(E) In many areas, glass bottles had to be sorted by color of the glass before being recycled, whereas aluminum cans required no sorting.——分类也不能改变数量
这题一开始选了A，注意注意。
24. 1:54
Tiger beetles are such fast runners that they can capture virtually any nonflying insect.However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
逻辑链：TB捕捉昆虫的时候，飞过去会停顿一会再飞——因为1，他刹不住2.因为视力调节跟不上——求解释
思路：如果是1，刹不住，那么当静止的
When a prey insect is moved directly toward a beetle that has been chasing it, the beetle immediately turns and runs away without its usual intermittent stopping.——跟掉头跑没什么关系吧
(B) In pursuing a moving insect, the beetles usually respond immediately to changes in the insect's direction, and pause equally frequently whether the chase is up or down an incline.——我原来选的是B，因为这样就能知道不是因为视力影响的——求解释
(C) The beetles maintain a fixed time interval between pauses, although when an insect that had been stationary begins to flee, the beetle increases its speed after its next pause.——是正确答案，但是不懂，求解释
(D) If, when a beetle pauses, it has not gained on the insect it is pursuing, the beetle generally ends its pursuit.——他放弃追虫子了，无关
(E) When an obstacle is suddenly introduced just in front of running beetles, the beetles sometimes stop immediately, but they never respond by running around the barrier.——两个都削弱了，视力又好又刹得住……好吧 |

nly gratification of these faculties can make people happy
