Machu Picchu is considered to be a truly extraordinary archaeological(考古学的) discovery and is one of South America’s largest tourist sites. As many as one thousand visitors visit the ancient Incan（印加文化的） ruins daily. What draws vacationers and adventurers to this remote location high in the Andes Mountains of Peru（秘鲁）? A large part of the attraction is the mysteries that surround Machu Picchu. For example, Machu Picchu is considered “the lost city” of the Incas because it was never found by Spanish invaders and was known to only a few local peasants for almost four hundred years.
The “city in the clouds”, Machu Picchu’s lasting beauty comes from the careful blending of its striking architecture with its mountaintop environment. Its greatest skill shows are in the stone structures, which equals that of the ancient Egyptians. The stone blocks were so appropriately cut that they fit together without the need for mud. The largest stones at Machu Picchu weigh as much as fifteen tons! It has been difficult to explain how the huge blocks were transported. The buildings, including many that have survived lots of earthquakes, contain stones which interlock so perfectly that a knife cannot be forced between them. When compared to other ancient civilizations, it is difficult to understand how Machu Picchu could have been missed by the Spanish and lost from history for four hundred years.
For many of the mysteries of Machu Picchu being unsolved, it is clear why Machu Picchu remains “the most famous ruins in all of South America”.

Wilderness
“In wilderness(荒野) is the preservation of the world.” This is a famous saying from a writer regarded as one of the fathers of environmentalism. The frequency with which it is borrowed mirrors a heated debate on environmental protection: whether to place wilderness at the heart of what is to be preserved.
As John Sauven of Greenpeace UK points out, there is a strong appeal in images of the wild, the untouched; more than anything else, they speak of the nature that many people value most dearly. The urge to leave the subject of such images untouched is strong, and the danger exploitation(开发) brings to such landscapes(景观) is real. Some of these wildernesses also perform functions that humans need—the rainforests, for example, store carbon in vast quantities. To Mr.Sauven, these ”ecosystem services” far outweigh the gains from exploitation.
Lee Lane, a visiting fellow at the Hudson Institute, takes the opposing view. He acknowledges that wildernesses do provide useful services, such as water conservation. But that is not, he argues, a reason to avoid all human presence, or indeed commercial and industrial exploitation. There are ever more people on the Earth, and they reasonably and rightfully want to have better lives, rather than merely struggle for survival. While the ways of using resources have improved, there is still a growing need for raw materials, and some wildernesses contain them in abundance. If they can be tapped without reducing the services those wildernesses provide, the argument goes, there is no further reason not to do so. Being untouched is not, in itself, a characteristic worth valuing above all others.
I look forwards to seeing these views taken further, and to their being challenged by the other participants. One challenge that suggests itself to me is that both cases need to take on the question of spiritual value a little more directly. And there is a practical question as to whether wildernesses can be exploited without harm.
This is a topic that calls for not only free expression of feelings, but also the guidance of reason. What position wilderness should enjoy in the preservation of the world obviously deserves much more serious thinking.
小题1:John Sauven holds that_____.
| A．many people value nature too much |
| B．exploitation of wildernesses is harmful |
| C．wildernesses provide humans with necessities |
| D．the urge to develop the ecosystem services is strong |
| A．The exploitation is necessary for the poor people. |
| B．Wildernesses cannot guarantee better use of raw materials. |
| C．Useful services of wildernesses are not the reason for no exploitation. |
| D．All the characteristics concerning the exploitation should be treated equally. |
| A．Objective. | B．Disapproving. |
| C．Sceptical. | D．Optimistic. |
A． | B． |
C． | D． |
Harvard researchers have created a tough, low-cost, biodegradable (可生物降解的) material inspired by insects" hard outer shells. The material"s inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative to plastic. The material, made from shrimp ("虾) shells and proteins produced from silk, is called "shrilk." It is thin, clear, flexible and strong.
A major benefit of the material is its biodegradability. Plastic"s toughness and flexibility represented a revolution in materials science during the 1950s and "60s. Decades later, however, plastic"s very durability (耐用性) is raising questions about how appropriate it is for one-time products such as plastic bags, or short-lived consumer goods, used in the home for a few years and then cast into a landfill where they will degrade for centuries. What is the point of making something that lasts 1,000 years?
Shrilk not only will degrade in a landfill, but its basic components are used as fertilizer(肥料), and so will enrich the soil.
Shrilk has great potential, the inventors said. Materials from which it is made are plentiful in nature, found in everything ranging from shrimp shells, insect bodies to living plants. That makes shrilk low cost, and its mass production possible should it be used for products demanding a lot of material.
Work on shrilk is continuing in the lab. The inventors said the material becomes flexible when wet, so they"re exploring ways to use it in wet environments. They"re also developing simpler production processes, which could be used for non-medical products, like for computer cases and other products inside the home. They"re even exploring combining it with other materials, like carbon fibers, to give it new properties.
小题1:Paragraph I of the passage is mainly about shritk"s_____.
| A．remarkable design | B．interesting name |
| C．major features | D．basic elements |
| A．Using it properly. |
| B．Producing it cheaply. |
| C．Developing its properties quickly. |
| D．Evaluating its contributions fairly. |
| A．it can help plastic degrade |
| B．it can be found in living things |
| C．its mass production has been realized |
| D．its raw materials are abundant in mature |
| A．Replacing carbon fibers with shrilk. |
| B．Testing ahrilk"s use in wet conditions. |
| C．Making shrilk out of used household goods. |
| D．Improving shrilk"s flexibility for medical purposes. |
| A．Recent Progress in Environmental Protection |
| B．Benefits of Insects in Scientific Research |
| C．The Harm of One-time Products |
| D．A Possible Alternative to Plastic |
Death Valley, one of America’s great national parks, is a place of strange and silent beauty. As beautiful as this place is, its name provides evidence of very real danger. Death Valley is a land of beautiful yet dangerous extremes. There are mountains that reach more than 3,000 meters into the sky. There is a place called Badwater that is the lowest area of land in the Western Hemisphere. If there were water there, it would be 86 meters below the level of the ocean.
Death Valley can be dangerously cold during the winter months. Storms in the mountains can produce sudden flooding on the floor of the Valley. The air temperature during the summer has been as high as 57℃. The sun can heat the ground so that the temperature of the rocks and soil can be as high as 74℃. The extreme heat of Death Valley has killed people in the past. It will continue to kill those who do not honor this extreme climate. Death Valley does not forgive those who are not careful.
Death Valley is a good example of the violence of nature. It contains evidence of several ancient volcanoes that caused huge explosions. Evidence of one of these explosions is called Ubehebe Crater. The explosion left a huge hole in the ground almost a kilometer and a half wide.
In many areas of Death Valley it is easy to see where the ground has been pushed up violently by movement deep in the Earth. This movement has created unusual and beautiful rock formations. Some are red. Others are dark brown, gray, yellow or black. Other areas of rock look as if some huge creature violently broke and twisted the Earth to create unusual, sometimes frightening shapes.
In other parts of Death Valley there are lines in the rock that show clearly that this area was deep under an ocean for many thousands of years. Much of the Valley is flat and extremely dry. In fact, scientists believe it is the driest place in the United States.
Death Valley, part of the Great Mojave Desert, is a huge place. It extends more than 225 kilometers across the southern part of California, and across the border with Nevada.

This week, the chairman of America’s nuclear agency said there is little chance that harmful radiation(辐射) from Japan could reach the United States. Gregory also said America has a strong program in place to deal with earthquake threats. No new nuclear power centers have been built in the United States since 1979. That was when America’s worst nuclear accident happened at the Three Mile Island center in Pennsylvania. The accident began to turn public opinion against nuclear energy. At present, about twenty percent of electricity in the United States comes from nuclear energy.
German Chancellor Angela Merkel said Germany would close seven nuclear power centers for the time being while energy policy is reconsidered. The European Union is planning to test all centers in its twenty-seven member nations.
Developing nations are less willing to slow down the development of nuclear. China says it will continue with plans to build about twenty-five new nuclear reactors(核反应堆). And India, under a cooperation agreement with the United States, plans to spend billions on new centers in the coming years.
Nuclear reactors supply fourteen percent of global electricity. Nuclear energy is a clean resource, producing no carbon gases. But radioactive waste is a serious problem to be solved. So is the presence of nuclear power centers in earthquake areas like the one near Bushehr, lran.
小题1:We can learn from the text that America ________.
| A．experienced a terrible nuclear accident 32 years ago |
| B．has a strong program to deal with radiation danger |
| C．depends heavily on nuclear energy to produce electricity |
| D．will check all the reactors before cooperating with India |
| A．German. | B．Iran | C．India. | D．China. |
| A．Satisfied. | B．Pleased. | C．Worried. | D．Surprised. |
| A．Various Opinions on Japan’s Nuclear Disaster |
| B．Japan’s Disaster is Likely to Run Out of Control |
| C．America Shows Great Concern for Japan’s Nuclear Crisis |
| D．Japan’s Disaster Throws Doubt on Nuclear Energy Industry |
