TPO5 THE CAMBRIAN EXPLOSION(寒武纪大爆发)
Scientists have asked important questions about this explosion for more than a century. Why did it occur so late in the history of Earth? The origin of multicellular forms of life seems a relatively simple step compared to the origin of life itself. Why does the fossil record not document the series of evolutionary changes during the evolution of animals? Why did animal life evolve so quickly? Paleontologists continue to search the fossil record for answers to these questions.
5. According to Paragraph2, which of the following is NOT a question that paleontologists asked about the Cambrian explosion?
1Why was the origin of life a simple step in Earth’s history?
2Why did it take so long for multicellular organisms to develop?
3Why did animal life evolve so rapidly?
4Why does the fossil record lack evidence of animal evolution during that time?
这题答案给1，我明白，可我觉得2也不对，怎么在这段看不出来哪里说了 multicelluar organism的develop???请求高人指点~~

should在这里是把前面的if省略掉了，是表达的假设的意思。也就是说“如果这种奖励机制失败了——”

同学请通看整体段落，作者只是在陈述事实，而没有任何个人感情色彩在里面的。那个important只是在对比环境因素中谁更重要来说的。

The writers seldom mention their sources of evidence , and thus we do not know what credence to give them.
them 的指代感觉 writers 和 sources 都合理

指这句话的主语，the writers.这个复杂句是个因果关系的句子，后面指代的会是前面的主语。

不好意思，请看帖子标题，是tpo疑问帖子。您的问题超出了我们的范围。如果同学有其他资料上的题目，请贴上全文，因为毕竟不是全部同学都一定有这本资料的。谢谢。
——当然我们更鼓励同学来研究tpo的题目，毕竟别的资料上的题目不是很标准的，我们无从下手。但并不是说除了tpo别的资料就没用了——建议当精读资料，或者复习单词和速度的资料，而不要拿题目出来研究。

Why did it occur so late in the history of Earth? The origin of multicellular forms of life seems a relatively simple step compared to the origin of life itself.这个过程看起来是个相对简单的步骤，但为什么发生这么晚呢？其实就是说它为什么用了这么长时间来完成这个过程。

这Should是倒装，表假设

与版主商榷一下。

指代关系不能简单的看句子成分。 不能因为是一个因果句就简单地认为后面的代词会指代前面的主语，指代关系与句子成份的关系没有必然联系。

最保险的做法仍旧是先看单复数，再代入理解。
从单复数角度看是 writers 和 sources 都合理。你把前面的seldom mention，和后面的credence连上，就不难理解了。

为什么不是选B， 文中红色部分说了the most important就是带有某种倾向性和支持性啊，

lynn27 发表于 2010-8-9 16:11

请读懂B选项中最关键的逻辑关系： argue  in support of one.... against several competing. 何为 argue.... against？ 不仅是支持一种，而且还要反对其他哦。 原文中并没有反对其他。

但是答案6也是细节啊，这个细节还是与主题TIMBERLINE有关阿。。。不能说只能选出现在第一句话的答案。再说我觉得2说得是错的 太过于笼统

请问TPO1中TIMBERLINE那篇文章的最后一题：
At the timberline, whether upper or lower, there is a profound change in the growth of trees and other plants.7 M. e, c' V" k; q1 _9 T9 w
选项2：There is no agreement among scientists as to exactly why plant growth is sharply different above and below the upper timberline.  为何是对的?8 i$ u" B& |9 D% Y
选项3：The temperature at the upper timberline is probably more important in preventing tree growth than factors such as the amount of snowfall or the force of winds.为何是错的？
依鄙人愚见 此题应该选3、4、6  请高人指点！
mresc 发表于 2010-8-10 10:06

选项2，来自第四段开头 There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline. Various environmental factors may play a role.

选项3当中的描述属于第二段中的细节。是从属于选项2的。摘要题的答案应选取抽象信息，所以不选第三个

TPO4:cave art in Europe
Paragraph 4：The particular symbolic significance of the cave paintings in southwestern France is more explicitly revealed, perhaps, by the results of a study conducted by researchers Patricia Rice and Ann Paterson. The data they present suggest that the animals portrayed in the cave paintings were mostly the ones that the painters preferred for meat and for materials such as hides. For example, wild cattle (bovines) and horses are portrayed more often than we would expect by chance, probably because they were larger and heavier (meatier) than other animals in the environment. In addition, the paintings mostly portray animals that the painters may have feared the most because of their size, speed, natural weapons such as tusks and horns, and the unpredictability of their behavior. That is, mammoths, bovines, and horses are portrayed more often than deer and reindeer. Thus, the paintings are consistent with the idea that the art is related to the importance of hunting in the economy of Upper Paleolithic people. Consistent with this idea, according to the investigators, is the fact that the art of the cultural period that followed the Upper Paleolithic also seems to reflect how people got their food. But in that period, when getting food no longer depended on hunting large game animals (because they were becoming extinct), the art ceased to focus on portrayals of animals.

11．According to paragraph 4, what change is evident in the art of the period following the Upper Paleolithic?
○This new art starts to depict small animals rather than large ones.
○This new art ceases to reflect the ways in which people obtained their food.
○This new art no longer consists mostly of representations of animals.
○This new art begins to show the importance of hunting to the economy.

我选D的 因为看到文章中蓝色的话...但看了很久都不懂为什么选C 求解...先谢谢~
