TPO1 - 第三篇的最后一题我还是有些疑问；
我觉得选项1的问题在于，原文中说for example，所以不能一概而论都是冰川留下的；
而第四个算是第一段中提到的一个很重要的特性，所以还是觉得可以作为一个要点的。

我觉得你解释得很对，谢谢你的热心参与。

但是您的解释得有点复杂。归结起来就是原文是 level of maturation support X, not Y，但是选项A把支不支持的概念偷换为重不重要，这就是A为什么错的原因。

我已经把前面的解释修改了。

TPO 7  第一篇
Paragraph 4: It seems likely that Teotihuacán’s natural resources, along with the city elite’s ability to recognize their potential, gave the city a competitive edge over its neighbors, The valley, like many other places in Mexican and Guatemalan highlands, was rich in obsidian. The hard volcanic stone was a resource that had been in great demand for many years, at least since the rise of the Olmecs (a people who flourished between 1200 and 400 B.C.), and it apparently had a secure market. Moreover, recent research on obsidian tools found at Olmecs sites has shown that some of the obsidian obtained by the Olmecs originated near Teotihuacán. Teotihuacán obsidian must have been recognized as a valuable commodity for many centuries before the great city arose.

9. Which of the following allowed Teotihuacán to have “a competitive edge over its neighbors”?
○A well-exploited and readily available commodity
○The presence of a highly stable elite class
○Knowledge derived directly from the Olmecs about the art of tool making
○Scarce natural resources in nearby areas such as those located in what are now the Guatemalan and Mexican highlands

答案选A  我选得是D
疑问在于
1.competitive edge over its neighbours的定位前面是“Teotihuacán’s natural resources, along with the city elite’s ability to recognize their potential”   那请问A是从哪里得来的啊？
2.弱弱的问下along with 是强调前面还是后面的？ 和这个题目定位有关系么？

Paragraph 4: Gigantothermy, though, would not be enough to keep a leatherback warm in cold northern waters. It is not enough for whales, which supplement it with a thick layer of insulating blubber (fat).
        Paragraph 5: Leatherbacks do not have blubber, but they do have a reptilian equivalent: thick, oil-saturated skin, with a layer of fibrous, fatty tissue just beneath a. Insulation protects the leatherback everywhere but on its head and flippers. Because the flippers are com paratively thin and blade like, they are the one part of the leatherback that is likely to become chilled. There is not much that the turtle can do about this without compromising the aerodynamic shape of the flipper. The problem is that as blood flows through the turtle's flippers, it risks losing enough heat to lower the animal's central body temperature when it returns. The solution is to allow the flippers to cool down without drawing heat away from the rest of the turtle's body. The leatherback accomplishes this by arranging the blood vessels in the base of as flipper into a countercurrent exchange system.
       
        According to paragraph 4, which of the following features enables the leatherback turtle to stay warm?
        ○An insulating layer of blubber
        ○A thick, oily skin covering fatty tissue
        ○The aerodynamic shape of its flippers
        ○A well-insulated head
        原来选的是C，后来看过答案后觉得B是对的。只是我在把后来的思路和考试时的错误思路在对比，发现很容易误选B。应该怎么排除B呢？
谢谢

TPO 8 的二道題請教，求各位高手幫我。。。

１。修辭目的題
Outflow channels are probably relics of catastrophic flooding on Mars long ago. They appear only in equatorial regions and generally do not form extensive interconnected networks. Instead, they are probably the paths taken by huge volumes of water draining from the southern highlands into the northern plains. The onrushing water arising from these flash floods likely also formed the odd teardrop-shaped “islands” (resembling the miniature versions seen in the wet sand of our beaches at low tide) that have been found on the plains close to the ends of the outflow channels. Judging from the width and depth of the channels, the flow rates must have been truly enormous―perhaps as much as a hundred times greater than the 105 tons per second carried by the great Amazon river. Flooding shaped the outflow channels approximately 3 billion years ago, about the same times as the northern volcanic plains formed.

5. In paragraph 2, why does the author include the information that 105 tons of water flow through the Amazon river per second?
○To emphasize the great size of the volume of water that seems to have flowed through Mars’ outflow channels
○To indicate data used by scientists to estimate how long ago Mars’ outflow channels were formed
○To argue that flash floods on Mars may have been powerful enough to cause tear-shaped “islands” to form
○To argue that the force of flood waters on Mars was powerful enough to shape the northern volcanic plains

A是正確答案。但為什麼不能選C？文中不是說 The onrushing water arising from these flash floods likely also formed the odd teardrop-shaped “islands” 嗎？

２。句子簡化題
These ideas remain controversial. Proponents point to features such as the terraced “beaches” shown in one image, which could conceivably have been left behind as a lake or ocean evaporated and the shoreline receded. But detractors maintain that the terraces could also have been created by geological activity, perhaps related to the geologic forces that depressed the Northern Hemisphere far below the level of the south, in which case they have nothing whatever to do with Martian water. Furthermore, Mars Global Surveyor data released in 2003 seem to indicate that the Martian surface contains too few carbonate rock layers―layers containing compounds of carbon and oxygen―that should have been formed in abundance in an ancient ocean. Their absence supports the picture of a cold, dry Mars that never experienced the extended mild period required to form lakes and oceans. However, more recent data imply that at least some parts of the planet did in fact experience long periods in the past during which liquid water existed on the surface.

Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
○But detractors argue that geological activity may be responsible for the water associated with the terraces.
○But detractors argue that the terraces may have been formed by geological activity rather than by the presence of water.
○But detractors argue that the terraces may be related to geological forces in the Northern Hemisphere of Mars, rather than to Martian water in the south.
○But detractors argue that geological forces depressed the Northern Hemisphere so far below the level of the south that the terraces could not have been formed by water.

答案是Ｂ。但我覺得Ｃ也可以！
