The Collapse of the Maya
The Mayan society of Central America (2000 B.C-A.D 1500), like other ancient states, was characterized by populations unprecedented both in their size and density. It was not just the number of people that lived in the Mayan city-states but also the relatively small area into which they were concentrated. To support such populations, societies developed various intensive agricultural including large-scale irrigation and hill-slope (the cutting of horizontal ridges into hillsides so they can be farmed). These were designed both to increase yields from a given area and to increase the absolute amount of land under cultivation. These strategies were in essence very successful: they made it possible to feed larger populations than ever before and supported the growth of cites. But they also placed considerable strains on the environment and rendered it increasingly fragile and vulnerable to unexpected climatic events, and even to short-term fluctuations. Thus, the argument is that because of their size and ever more intensive agriculture, the Mayan and other ancient state societies were fundamentally unsustainable.
1.According to paragraph 1, ancient societies increased their agricultural output by
A.increasing the percentage of the population that worked as farmers
B.creating large irrigation systems
C.being highly selective of the fields they would farm
D.moving more people into the city to free up farmland
2.Which of the following can be inferred from paragraph 1 about the intensive agricultural methods of the Maya?
A.They helped the Maya overcome short-term fluctuations in the climate.
B.They could not supply all of the food required for the growth of Mayan cities.
C.They strained the environment more than the Maya’s previous farming techniques did.
D.They were invented by the Maya to help them grow new kinds of crops.
Claims about environment degradation and disaster have figured prominently in discussion of the collapse of the Mayan city-states of the Central American lowlands. When two explorers came upon the Mayan cities in the 1830s, they were struck by the sight of tall pyramids and elaborately carved stones among luxuriant forest growth. Here was the archetypal picture of a great lost civilization: abandoned cities submerged in vegetation. Theories of catastrophic collapse or apocalyptic overthrow came naturally to mind to explain these dramatic scenes.
3.The word “abandoned” in the passage is closet in meaning to
A.carefully hidden B. destroyed
C. enormous D. no longer occupied
Recent studies of the Mayan collapse (beginning around A.D 900) have emphasized the gradual and progressive nature of the process, beginning in the earliest in the South and advancing northward. It was not a single, sudden event, as had once been thought. Warfare and social unrest are thought to have played a part, but these may well have arisen through pressure from other causes. The Mayan cities had, after all, flourished for over 500 years and had frequently been at war with each other.
4.Why does the author include the information that Mayan cities had “flourished for over 500 years and had frequently been at war with each other”?
A.To identify a possible reason for the eventual collapse of Mayan society.
B.To make the point that war and social unrest alone do not account for the Mayan collapse.
C.To explain why recent studies argue that human actions were responsible for the Mayan collapse
D.To provide evidence that frequent wars weakened Mayan society only very gradually
5.According to paragraph 3, recent studies claim which of the following about the Mayan collapse?
A.It was caused primarily by frequent wars between rival city-states.
B.It was caused by a single sudden event.
C.It was preceded by social unrest in northern city-states.
D.It began in southern city-states and spread to others.
But what about the possibility of food shortage? These could have come about through either natural or humanly induced changes in the environment. Increasingly fierce competition between Mayan cities led to an upsurge of monument construction during the eighth and ninth centuries A.D, which would have placed added strain on agricultural production and expansion. Interstate rivalry may hence have pushed the Maya toward overexploitation of their fragile ecosystem. Deforestation and soil erosion might ultimately have destroyed the capacity of the land to support the high population levels of the Mayan cities, leading to famine, social unrest, and the collapse of the major Mayan centers.
6.All of the following are mentioned in paragraph 4 as possible direct or indirect caused of food shortages EXCEPT
A.increased monument construction
B.rivalries between states
C.deforestation and erosion
D.introduction of new crops
Yet it may be incorrect to lay the blame entirely on human action. Several of the lowland cities, such as Tikal, appear to have depended heavily on the cultivation of raised fields set in the marshy depressions known as bajos, which today flood intermittently in the rainy season but may originally have been permanent lakes. The raise-field system of intensive cultivation (created by digging surrounding canals and using the soil removed to elevate the fields for planting) allows year-round food production through the constant supply of soil nutrients that erode into the drainage ditches dug around the raised fields, nutrients that are then collected and replaced. Stable water levels were essential to this subsistence system, but evidence from Lake Chichancanab in Yucatan shows that between A.D 800 and A.D 1000 this region suffered its driest period of climate in several thousand years. We may expect that as a result water level fell, and the raised fields in many areas became unusable. But the human response must be viewed through the lens of the social, political, and cultural circumstances. These exerted a powerful mediating effect on the way the Maya endeavored to cope with their difficulties. Had population levels been lower, the impact of the drought may not have been catastrophic, as it was, the Maya were already reaching the limits of the available subsistence capacity, and Mayan elites had espoused certain social and political agendas (including expensive warfare and competition with each other).It was against this specific background that a period of drought led quickly to crisis and collapse.
7.The word “intermittently” in the passage is closet in meaning to
A constantly B periodically
C usually D especially
8.According to paragraph 5, why did the raised fields in many areas become unusable?
A.The marshy depressions around the fields flooded in the rainy season
B.Intensive cultivation of the fields drained the soil of nutrients.
C.The area where the fields were located experienced a drop in water levels.
D.Unstable design caused the failure of the drainage ditches.

9.Look at the four squares [_] that indicate where the following sentence could be added to the passage.
Nature apparently also contributed to the food shortages.
Where would the sentence best fit?
10.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.
Since the discovery of the Mayan ruins in the 1830s, researchers have tried to explain the collapse of Mayan civilization.
A.The Mayan attempt to develop intensive agricultural methods to support large populations in relatively small areas probably was unsuccessful and could have caused the Mayan collapse.
B.The discovery of intact pyramids submerged in vegetation among the Mayan ruins led researchers to believe that Mayan cities were simply overgrown rather than catastrophically destroyed.
C.Warfare and rivalry between Mayan states may have caused food shortages that contributed to the eventual collapse of Mayan civilization.
D.Early theories that the Mayan collapse was a sudden, catastrophic event were followed by views that treated the collapse as a gradual process.
E.The continuing warfare and social unrest that started in the North and spread to the South provided researchers with evidence that the Mayan collapse took hundreds of years to occur.
F.Drought between A.D. 800 and A.D. 1000 likely caused the Mayan system of intensive irrigated agriculture to fall, which could have brought about a rapid collapse of the Mayan State.
Inca Highlands Adaptations
P2：但是erratic climate和thin soil等不利条件还是会影响农业或者牧业。
P3：因此当地人想了多种解决办法。第 一个就是“ecological complementarity”或者“verticality”。就是在不同海拔高度相邻的地方种植各种不同的作物，万一一种作物受灾了，其他作物还能活。
P2：predatory bacteria这种小的体型可能speed更快，能够快速攻击 prey。但是这种说法controversial，因为这种方式只在静水里面比较有效果，因为小的 bacteria 更容易被水流冲走，无法到达目的地。
P3：也有可能因为小的体型更容易attach到大size的prey上面。另外，它有rigid cell wall，这个cell wall虽然可以保护自身，却也限制了它不能变形，不像amoeba（阿米巴虫，一种变形虫）一样可以变形吞噬prey
P5：predatory bacteria可以用来control cyanobacteria（蓝细菌）的泛滥。因为他们可以吃cyanobacteria。但是这种情况在静水里面会更有效果，在open sea就没有那么有效果

Imagine you are working on a group project with two coworkers and the deadline (the time that the project should be submitted) is approaching. The project looks good but could be improved if you all work on it more; however, this would mean that you miss the deadline. One of your coworkers suggests submitting the project in its current condition to meet the deadline, while your other coworker thinks it is better to wait and submit the project after the deadline so that it is perfect. Which approach is better in your opinion: meeting deadlines even if a project is not yet perfect or submitting a project after a deadline so that it is perfect? Why?
