TPO13  Biological Clocks



14. Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.

The activity of animals is usually coordinated with periodically recurring events in the environment.

●

Answer Choices

○ Most animals survive and reproduce successfully without coordinating their activities to external environmental rhythms.

○ The circadian period of an animal's internal clock is genetically determined and basically unchangeable.

○ Environmental cues such as a change in temperature are enough to reset an animal's clock.

○ Animals have internal clocks that influence their activities even when environmental cues are absent.

○ Animals are less affected by large differences between their internal rhythms and the local solar day than are humans

○ Because an animal's internal clock does not operate on a 24-hour cycle, environmental stimuli are needed to keep the biological day aligned with the solar day.
第二个是从哪里看出来的~~

TPO 7
Paragraph 3 Certainly, in trying to explain the Roman phenomenon, one would have to place great emphasis on this almost instinct for the territorial imperative. Roman priorities lay in the organization, exploitation, and defense of their territory. In all probability it was the fertile plain of Latium, where the Latins who founded Rome originated, that created the habits and skills of landed settlement, landed property, landed economy, landed administration, and a land-based society. From this arose the Roman genius for military organization and orderly government. In turn, a deep attachment to the land, and to the stability which rural life engenders, fostered the Roman virtues: gravitas, a sense of responsibility, peitas, a sense of devotion to family and country, and iustitia, a sense of the natural order.
7．
Paragraph 3 suggests which of the following about the people of Latium?
○Their economy was based on trade relations with other settlements.
○They held different values than the people of Rome.
○Agriculture played a significant role in the society.
○They possessed unusual knowledge of animal instincts
答案是C，我想知道是从哪里看出来的，是不是因为文中提到了Latium是个fertile plain所以就选C了啊




Paragraph 4 Modern attitudes to Roman civilization range from the infinitely impressed to the thorough disgusted. As always, there are the power worshippers, especially among historians, who are predisposed to admire whatever is strong, who feel more attracted to the might of Rome than to the subtlety of Greece. At the same time, there is a solid body of opinion that dislikes Rome. For many, Rome is at best the imitator and the continuator of Greece on a larger scale. Greek civilization had quality; Rome, mere quantity. Greece was the inventor; Rome, the research and development division. Such indeed was the opinion of some of the more intellectual Romans.” had the Greeks held novelty in such disdain as we,” asked Horace in his Epistle, “what work of ancient date would now exist?”
10.
According to paragraph 4, intellectual Romans such as Horace held which of the following opinions about their civilization?
○Ancient works of Greece held little value in the Roman world.
○The Greek civilization had been surpassed by the Romans.
○Roman civilization produced little that was original or memorable.
○Romans valued certain types of innovations that had been ignored by ancient Greeks.
答案是C，我想知道划线句的意思。这段从at the same time开始反驳对罗马的赞颂，认为罗马是对希腊的copy，那划线句是不是也包含同样的意思呢？






Paragraph 3 Iron came from West Asia, although its routes of diffusion were somewhat different than those of agriculture. Most of Africa presents a curious case in which societies moved directly from a technology of stone to iron without passing through the intermediate stage of copper or bronze metallurgy, although some early copper-working sites have been found in West Africa. Knowledge of iron making penetrated into the forest and savannahs of West Africa at roughly the same time that iron making was reaching Europe. Evidence of iron making has been found in Nigeria, Ghana, and Mali.
6.
What function does paragraph 3 serve in the organization of the passage as a whole
○It contrasts the development of iron technology in West Asia and West Africa.
○It discusses a non-agricultural contribution to Africa from Asia.
○It introduces evidence that a knowledge of copper working reached Africa and Europe at the same time.
○It compares the rates at which iron technology developed in different parts of Africa.
额，这道题目问题有点不太懂，是不是说第三段的什么功能把文章的组织捏为一体了？

4．Which of the following can be inferred from paragraph 3 about the solid gypsum layer
○It did not contain any marine fossil.
○It had formed in open-ocean conditions
○It had once been soft, deep-sea mud.
○It contained sediment from nearby desertsni
=>你选A是中了偷换概念的圈套。看清楚。
原文说。。Sediment above and below the gypsum layer contained
tiny marine fossils
D在原文也提到过：Furthermore, the gypsum was found to possess peculiarities of composition and structure that suggested it had formed on desert

6 问的是main purpose
你排除了C D 那么剩下A B
A和B我不看题目就直接选了。我只是觉得A犯错概率低。main purpose题说得越多 越细节 代表出错的可能性越大。 呵呵~~

这题有意思。。咣咣咣说了一大段。
从when开始就要有感觉。。这家伙预备描述了。。其实描述的东西就。。忽略吧。。
要知道这个文章呢，是要论证一个现象或者一个发现或者一个道理。肯定是要有结论的。当然 变态点的会用长长的论去迷惑你。这里的论就是"when...." 很明显地，它在用例子描述一个什么东西。接着扫扫扫，突然看见了Indeed, stability of the biological clock's period is one of its major features, even when the organism's environment is subjected to considerable changes in factors。
哈哈。。 结论有点苗头了。。 说了，生物钟的一大特性就是稳定，尽管呢,环境在变化着。
=>就是C了。 presenting cases to。。。
ps:这题不是定位，我个人觉得考的是眼力+头脑清晰度。

TPO 5 The Cambrian Explosion


最後一題:


1. Little is known about the stages of evolution during the Cambrian period, in part because early animals were soft bodied and could fossilize only under particular conditions.
2. While animal fossils from before the Cambrian explosion have no modern descendants, many animals that evolved during the Cambrian explosion can be assigned to modern groups.
3. The Cambrian period is significant because it marks the emergence of eukaryotic life-forms – organisms that have cells with true nuclei
4. The Ediacara fossil formation provides the most information about the Cambrian explosion, while the earlier, Tommotian and Burgess Shale formations give clues about Precambrian evolution.
5. Zoologists are awaiting the discovery of a 600-million-year-old fossil formation in order to be able to form a theory of how animal evolution progressed.
6. Although the reasons for the rapid evolution of animals during the Cambrian period are not known, one proposed explanation is an abundance of niches with a lack of competitors.


為什麼選項2是對的?

TPO4  Deer Populations of the Puget Sound1 i0 B  f1 O6 F   L3 h- E* h" [' ~Paragraph 2: Nearly any kind of plant of the forest understory can be part of a deer's diet. Where the forest inhibits the growth of grass and other meadow plants, the black-tailed deer browses on huckleberry, salad, dogwood, and almost any other shrub or herb. But this is fair-weather feeding. What keeps the black-tailed deer alive in the harsher seasons of plant decay and dormancy? One compensation for not hibernating is the built-in urge to migrate. Deer may move from high-elevation browse areas in summer down to the lowland areas in late fall. Even with snow on the ground, the high bushy understory is exposed; also snow and wind bring down leafy branches of cedar, hemlock, red alder, and other arboreal fodder. 4 o: V$ Q: g0 |2 ~% s5 q ' r6 {.

Petroleum, consisting of crude oil and natural gas, seems to originate from organic matter in marine sediment. Microscopic organisms settle to the seafloor and accumulate in marine mud. The organic matter may partially decompose, using up the dissolved oxygen in the sediment. As soon as the oxygen is gone, decay stops and the remaining organic matter is preserved.

2．According to paragraph 1, which of the following is true about petroleum formation?
○Microscopic organisms that live in mud produce crude oil and natural gas.
○Large amounts of oxygen are needed for petroleum formation to begin.
○Petroleum is produced when organic material in sediments combines with decaying marine organisms.
○Petroleum formation appears to begin in marine sediments where organic matter is present.
这道题我不是问别的，是问有没有快捷的方法？虽说有关键词可以找 但是不幸的是这段都在讲跟关键词有关的。这个题我做了2min虽然对了 但是求速解方法！
