Paragraph 4: Nomadism also subjects pastoralist communities to strict rules of portability. If you are constantly on the move, you cannot afford to accumulate large material surpluses. Such rules limit variations in accumulated material goods between pastoralist households (though they may also encourage a taste for portable goods of high value such as silks or jewelry). So, by and large, nomadism implies a high degree of self-sufficiency and inhibits the appearance of an extensive division of labor. Inequalities of wealth and rank certainly exist, and have probably existed in most pastoralist societies, but except in periods of military conquest, they are normally too slight to generate the stable, hereditary hierarchies that are usually implied by the use of the term class. Inequalities of gender have also existed in pastoralist societies, but they seem to have been softened by the absence of steep hierarchies of wealth in most communities, and also by the requirement that women acquire most of the skills of men, including, often, their military skills.
10 According to paragraph 4, all of the following are true of social inequality in pastoralist societies EXCEPT:
○ It exists and has existed to some degree in most pastoral societies.
○ It is most marked during periods of military conquest.
○ It is expressed in the form of a rigid hierarchy based largely on heredity.
○It is usually too insignificant to be discussed in terms of class differences.

答案是C，我选的是D

不要盲目相信XDF老师讲的东西。要看是不是符合考试实际和你的实际情况。 要有自己的判断力

TPI11 Begging by Nestlings
Further evidence for the costs of begging comes from a study of differences in the begging calls of warbler species that nest on the ground versus those that nest in the relative safety of trees. The young of ground-nesting warblers produce begging cheeps of higher frequencies than do their tree-nesting relatives. These higher-frequency sounds do not travel as far, and so may better conceal the individuals producing them, who are especially vulnerable to predators in their ground nests. David Haskell created artificial nests with clay eggs and placed them on the ground beside a tape recorder that played the begging calls of either tree-nesting or of ground-nesting warblers. The eggs “advertised” by the tree-nesters' begging calls were found bitten significantly more often than the eggs associated with the ground-nesters' calls.

4. Paragraph 2 indicates that the begging calls of tree nesting warblers

○ put them at more risk than ground-nesting warblers experience

○ can be heard from a greater distance than those of ground-nesting warblers

○ are more likely to conceal the signaler than those of ground-nesting warblers

○ have higher frequencies than those of ground nesting warblers

这道题 我怎么觉得  A 和 B 都对啊~~  红色字部分是什么意思~~特别是were found bitten~~  我感觉最后一句话跟A刚好对应啊~~   那A错在哪里~

The eggs “advertised” by the tree-nesters' begging calls were found bitten significantly more often than the eggs associated with the ground-nesters' calls.
. The experiment described in paragraph 2 supports which of the following conclusions?

○ Predators are unable to distinguish between the begging cheeps of ground-nesting and those of tree-nesting warblers except by the differing frequencies of the calls.

○ When they can find them, predators prefer the eggs of tree-nesting warblers to those of ground-nesting warblers.

○ The higher frequencies of the begging cheeps of ground-nesting warblers are an adaptation to the threat that ground-nesting birds face from predators

○ The danger of begging depends more on the frequency of the begging cheep than on how loud it is.

为社么答案是C  C答案里的adaptation to threat是哪里看出来的~

这句话的实体是：eggs A were found bitten more often than eggs B.
A->tree-nesters' begging calls   B->ground-nesters' calls
这样你也不用纠结什么were found bitten之类的意思了吧。。
这题很明显就是Choice 2

定位:The young of ground-nesting warblers produce begging cheeps of higher frequencies than do their tree-nesting relatives. These higher-frequency sounds do not travel as far, and so may better conceal the individuals producing them, who are especially vulnerable to predators in their ground nests

不知道你有没有感觉出来 这段话的意思是因为声音的传播远近问题 导致了这些鸟的安全程度高低。
Choice1重点放错了。且注意这句话who are especially vulnerable to 。。。 说的是G-N warble比较脆弱。安全度低。
至于你说的最后一句话和choice1对应。。呵呵~ 我没看出来啊~~

这题我直接看选项。没有定位。
用排除法做就好了。
偶尔用必要性思维做 能做对是我们的目标嘛。。

Paragraph2: Glaciers are open systems, with snow as the system's input and melt water as the system’s main output. The glacial system is governed by two basic climatic variables: precipitation and temperature. For a glacier to grow or maintain its mass there must be sufficient snowfall to match or exceed the annual loss through melting, evaporation, and calving, which occurs when the glacier loses solid chunks as icebergs to the sea or to large lakes. If summer temperatures are high for too long, then all the snowfall from the previous winter will melt. Surplus snowfall is essential for a glacier to develop. A surplus allows snow to accumulate and for the pressure of snow accumulated over the years to transform buried snow into glacial ice with a depth great enough for the ice to flow. Glaciers are sometimes classified by temperature as faster-flowing temperate glaciers or as slower-flowing polar glaciers.

6. Paragraph 2 implies that which of the following conditions produces the fastest moving glaciers?

○A climate characteristic of the Polar Regions

○A thick layer of ice in a temperate climate F Long,

○Warm summers

○Snow, firm and ice that have been buried for several years

答案是B,我选的是C。我B的定位在文章中没有找到啊。


Paragraph3: Glaciers are part of Earth's hydrologic cycle and are second only to the oceans in the total amount of water contained. About 2 percent of Earth's water is currently frozen as ice. Two percent may be a deceiving figure, however, since over 80 percent of the world's freshwater is locked up as ice in glaciers, with the majority of it in Antarctica. The total amount of ice is even more awesome if we estimate the water released upon the hypothetical melting of the world's glaciers. Sea level would rise about 60 meters. This would change the geography of the planet considerably. In contrast, should another ice age occur, sea level would drop drastically. During the last ice age, sea level dropped about 120 meters.

9. The discussion in paragraph 3 answers all the following questions EXCEPT:

○Where is most of Earth's freshwater?

○What effect would a new ice age have on sea levels?

○What is the total amount of water in Earth's oceans?

○How much of Earth's water is in ice?

答案是C，我选的是A，文中地点没提到吧？难道locked up as ice in glaciers也算是一种地点？

Paragraph 3 With question such as these clearly before them, the scientists aboard the Glomar Challenger processed to the Mediterranean to search for the answers. On August 23, 1970, they recovered a sample. The sample consisted of pebbles of gypsum and fragments of volcanic rock. Not a single pebble was found that might have indicated that the pebbles came from the nearby continent. In the days following, samples of solid gypsum were repeatedly brought on deck as drilling operations penetrated the seafloor. Furthermore, the gypsum was found to possess peculiarities of composition and structure that suggested it had formed on desert flats. Sediment above and below the gypsum layer contained tiny marine fossils, indicating open-ocean conditions. As they drilled into the central and deepest part of the Mediterranean basin, the scientists took solid, shiny, crystalline salt from the core barrel. Interbedded with the salt were thin layers of what appeared to be windblown silt.

3．What does the author imply by saying “Not a single pebble was found that might have indicated that the pebbles came from the nearby continent”?
○The most obvious explanation for the origin of the pebbles was not supported by the evidence.
○The geologists did not find as many pebbles as they expected.
○The geologists were looking for a particular kind of pebble.

○The different pebbles could not have come from only one source.

这个句子没有看懂，做也没做对，惭愧，请大侠们指点一下！句子的意思是什么？

Paragraph 2 How did this tremendous development take place, and why did it happen in the Teotihuacán Valley? Among the main factors are Teotihuacán’s geographic location on a natural trade route to the south and east of the Valley of Mexico, the obsidian resources in the Teotihuacán Valley itself, and the valley’s potential for extensive irrigation. The exact role of other factors is much more difficult to pinpoint―for instance, Teotihuacán’s religious significance as a shrine, the historical situation in and around the Valley of Mexico toward the end of the first millennium B.C., the ingenuity and foresightedness of Teotihuacán’s elite, and, finally, the impact of natural disasters, such as the volcanic eruptions of the late first millennium B.C.

3. The word pinpoint in the passage is closest in meaning to
○identify precisely
○make an argument for
○describe
○understand

这个pinpoint的意思是：找出或描述，答案怎么会选择第一个？

我相信新东方老师说的肯定是快速通读之后，再看题回原文定位，并且采用直选法（就是你说的看到正确的就把它选出来，不用把其他选项再看一遍）。

回文定位+直选法是既快又能保证正确的两个步骤 ...
jsssd 发表于 2010-8-8 13:29

“直选法”根本不能叫一种“法”。把这种解题的步骤上升为一种“法”，太搞笑了。

正确的标准是什么？ 原文的同意替换？ 可惜这种直选法已经很难做对TPO的题了。TPO中细节题越来越多考察整段的逻辑关系。
