⑴ 求一篇关于环境保护的高一英语阅读理解
A desert is a beautiful land of silence and space. The sun shines, the wind blows, and time and space seem endless. Nothing is soft. The sand and rocks are hard, and many of the plants even have hard needles instead of leaves. The size and location(分布) of the world’s deserts are always changing. Over millions of years, as climates change and mountains rise, new dry and wet areas develop. But within the last 100 yeas, deserts have been growing at a frightening speed. This is partly because of natural changes, but the greatest makers are humans.Humans can make deserts, but humans can also prevent their growth. Algeria Mauritania is planting a similar wall around Nouakchott, the capital. Iran puts a thin covering of petroleum(石油) on sandy areas and plants trees. The oil keeps the water and small trees in the land, and men on motorcycles(摩托车) keep the sheep and goats away. The USSR and India are building long canals to bring water to desert areas.
1. In this passage, “needles” refers to ___.
A. small, thin pieces of steel. B. long, thinieces of branches.
C. small pointed growth on the stem(茎) of a plant. D. small, thin pieces of sticks.
2. Which of the following is NOT true?
A. The greatest desert makers are humans. B. There aren’t any living things in the deserts.
C. Deserts have been growing quickly. D. The size of the deserts is always changing.
3. People in some countries are fighting a battle against __.
A. the growth of deserts B. the disappearance of desert plants
C. natural changes D. congenital climate
4. We can guess that Mauritania and Algeria belong to __.
A. Asian countries B. American countries
C. European counties D. African countries
【答案与解析】文章主要讲的是人们正采取措施控制和治理沙漠。
1. C。词汇猜测题。从instead of leaves可知needles是沙漠中植物的叶子，众所周知沙漠中植物的叶子是针状的, 再看steel(钢) 、) branches(树枝) 、stick(棒) 都不是与叶对应的物体, 只有C项(长在植物茎上的尖的小物体)是“是针状叶”的意思，故答案选C。
2. B。细节题。从many of the plants even have hard needles instead of leaves可知B项错误。
3. A。细节题。从Humans can make deserts, but humans can also prevent their growth(认为可能造成沙漠，但人类也可以防止沙漠的增长)可知答案A正确。
4. D。推断题。根据常识非洲沙漠远近闻名, 这说明那里最需要治理, 作者举例也会举典型的, 增加文章的可信度，故答案选D。

Fossil energy and nuclear energy are considered nonrenewable energy
types. Nonrenewable energy is obtained from sources at a rate that exceeds
the rate at which the sources are replenished. For example, if the biogenic
origin of fossil fuels is correct, we could consider fossil fuels renewable
over a period of millions of years, but the existing store of fossil fuels is
being consumed over a period of centuries. Because we are consuming
fossil fuels at a rate that exceeds the rate of replenishment, we consider
fossil fuels nonrenewable. Similar comments apply to nuclear fuels such
as uranium, as we observe in later chapters. Solar energy is considered
a renewable energy for the following reasons.1
Renewable energy is energy obtained from sources at a rate that is less
than or equal to the rate at which the source is replenished. In the case
of solar energy, we can use only the amount of energy provided by the
sun. Because the remaining lifetime of the sun is measured in millions
of years, many people consider solar energy an inexhaustible supply of
energy. In fact, solar energy from the sun is finite, but should be available
for use by many generations of people. Solar energy is therefore considered
renewable. Energy sources that are associated with solar energy, such as
wind and biomass, are also considered renewable.
Solar radiation may be converted to other forms of energy by several
conversion processes. Thermal conversion relies on the absorption of solar
energy to heat a cool surface. Biological conversion of solar energy relies
on photosynthesis. Photovoltaic conversion generates electrical power by
the generation of an electrical current as a result of a quantum mechanical
process. Wind power and ocean energy conversion rely on atmospheric
pressure gradients and oceanic temperature gradients to generate electrical
power. In this chapter we focus on thermal conversion.We first discuss the
source of available solar energy, and then consider solar energy technology
in two of its three forms: passive solar, and active solar. The third form of
solar energy, solar electric, is discussed in the next chapter. We end this
chapter with a discussion of solar power plants.
Fossil fuels in the petroleum and natural gas is the world's major one-time energy World Energy Council, according to statistics, has proven oil and gas recoverable reserves, according to the output of countries in 1992 terms, respectively, only the exploitation of 44 years and 60 years; although they may be recoverable reserves there will be new discoveries, but also the growth needs of the community, especially taking into account the economic development of Third World countries, the exploitation of oil and gas fuel for a long time. In fossil fuels, although the most abundant coal reserves, but the serious pollution caused by coal-fired so that it can not become large the major source of energy worldwide. On the other hand, nuclear fusion reactions can provide clean energy, in the ocean contains about 42 trillion tons of the major nuclear fusion of deuterium-reactive substances; fusion reactor but it is very difficult to study, it is estimated that the next century to the late nuclear poly substation be possible to achieve widespread commercialization. Therefore, in the 21st century, the prospects for energy, you may have to face the depletion of oil and gas resources, the commercialization of fusion power failure ring the period of temporary shortage of such people. During this period in order to ensure sufficient human clean energy supply, use of solar energy for power generation is an inevitable choice.
Solar energy is the most important renewable sources of energy, the planet with all kinds of energy are closely related. In fact, the sun in Earth's evolution, biological reproction and human development, plays a very important role, but also provides a human inexhaustible source of energy. Solar interior ongoing response to the release of a high-temperature nuclear fusion power of about 3. 8 × 1026 watts of huge radiation, of which only arrived in regard to the atmospheric level二十亿分之一; through the atmosphere, about 30% reflected, 23% be absorbed, only half (approximately 8 × 1016 watts) of energy reaching the earth's surface. Even so, as long as they can make use of the very few, will be able to meet all the needs of humanity today. However, e to its low energy density, but also by the day and night, seasons, climate, location and other factors, on the ground by the use of solar energy to power a lot of constraints. In order to avoid these shortcomings, natural to consider the use of solar power in space of the feasibility of the possibility.
Power generation in 2010 is expected to the practical use of space
Space Solar Power is the first way of Engineers first proposed by P. Glaser. The basic idea is in the earth's outer space or the moon to establish a base of solar power satellites, and then through the microwave energy transmitted to the scene to the receiving device, and then beam microwave energy into electrical energy for human use. Advantage of this program is to make full use of solar energy outside the atmosphere, the elimination of solar energy in the ground, changes in the density of small and large shortcomings, without a huge energy storage device, not only to rece the square, but also save a lot of equipment investment. It can be expected, with the photoelectric conversion materials and delivery areas such as technology, space solar power generation costs will be greatly reced.
The idea is proposed, subject to national attention. 1977 -1980 in the United States Department of Energy and NASA organizations to the concept of space solar power study, believe that its implementation does not exist insurmountable technical difficulties. At that time, a design known as the "reference system" of power generation systems; from 60 to solar panels, each block 10 kilometers long, five kilometers wide, generating 5,000,000 kilowatts, with a total capacity of 300 million kilowatts. With such a power generation satellites, the United States will be able to replace all of the ground station. As the system is too large, about 3,000 of the money to invest 100 billion U.S. dollars, at that time under the conditions of the Cold War can hardly be supported. With the energy of all the outstanding progress in space technology in 1995, NASA set up a study group to re-examine this issue, a more comprehensive analysis of space solar power generation technical and economic feasibility of the program also are very different: adopted a progressive self-development model, that is, the first 100-150 to launch a 100 million U.S. dollars investment for 250,000 kilowatts of power satellites, the sale of electricity in order to recover their investment and profit, and then expand the scale of power generation satellites. The research group estimates that after 2010, space power will be practical. At present, a number of other countries and international organizations, space solar power generation is also carried out work.化石燃料中的石油天然气是当今世界的主要一次性能源据世界能源委员会统计，已探明的石油、天然气可采储量，按 1992 年各国的产量计算，分别只能开采 44 年和 60 年；虽然可采储量还会有新的发现，但社会需求也有增长，特别是考虑到第三世界国家的经济发展，油气燃料可供开采的时间不会很长。在化石燃料中，尽管煤炭的储量最为丰富，但燃煤造成的严重污染使其大不可能成为世界范围的主要能源。另一方面，核聚变反应可提供清洁的能源，在海洋中蕴藏着约 42 万亿吨核聚变的主要反应物质氘；但核聚变堆研究的难度很大，估计要到下一世纪后期核聚变电站广泛出现才有可能实现商品化。因此， 在展望 21 世纪能源问题的前景时，可能不得不对油气资源面临枯竭、核聚变发电又未能商品化的一段青黄不接时期。为保证这一时期内人类有充足的清洁能源供应，利用太阳能来发电是一种必然的选择 。
太阳能是最重要的可再生能源，地球上各种能源无不与之密切相关。事实上，太阳在地球的演化、生物的繁衍和人类的发展中，起了无比重要的作用，也为人类提供了取之不尽的能源。太阳内部不断进行的高温核聚变反应释放着功率约为 3. 8 × 1026 瓦的巨大辐射能，其中只有二十亿分之一到达至于大气高层；经过大气时，约 30% 被反射， 23% 被吸收，仅有一半（约 8 × 1016 瓦）的能量到达地球表面。即使如此，只要能够利用其万分之几，便可满足今日人类的全部需要。但是，由于其能量密度低，还要受昼夜、季节、气候、地点等因素的影响，在地面上利用太阳能来发电受到很大限制。为了避免这些缺点，自然要考虑在空间利用太阳能发电的可能性各可行性。
2010 年空间发电可望实用化
空间太阳能发电方式最初是 美国工程师 P.Glaser 首先提出的。其基本构想是在地球的外层空间或月球上建立太阳能卫星发电基地，然后通过微波将电能传输到场面的接收装置，再把微波能束转变成电能供人类使用 。这一方案的优点是在大气层外充分利用太阳能，消除了在地面上太阳能密度小而变化大的缺点，无需庞大的储能装置，既减少占地，又节约大量设备投资。可以预计，随着光电转化材料和运载等方面技术的进步，太阳能空间发电的成本将大大降低。
这一设想提出后，受到了各国的重视。 1977 年 —1980 年美国能源部和航天航空局组织对空间太阳发电的概念进行研究，认为其实施不存在不可克服的技术困难。当时设计了一种称为“参考系”的发电系统；由 60 地太阳能面板组成，每块长 10 公里，宽 5 公里，发电 500 万千瓦，总发电量为 3 亿千瓦。用这样一颗发电卫星，便可取代美国所有的地面电站。由于该系统过于庞大，约需 3000 千亿美元的巨资投资，在当时冷战的条件下难以得到支持。随着能源问题的突出各航天技术的进步， 1995 年美国航天航空局成立研究组，重新审视这一问题，较全面地分析了空间太阳能发电的技术经济可行性，在方案上也有很大不同：采用渐进的自我发展模式，即先发射一颗投资为 100—150 亿美元的 25 万千瓦发电卫星，出售电力以回收投资并获取利润，然后再扩大发电卫星的规模。该研究组估计， 2010 年以后，空间发电将实用化。目前，其他一些国家和国际组织也在进行太阳能空间发电方面的工作。

请记住全球变暖？早在12月，气候变化的威胁是雷鸣般的和富有的国家同意削减其二氧化碳和其他温室有关的排放量。自那时以来，兴趣明显降温，和许多欧洲国家已经在运行远离作出的承诺，使他们大声几个月前。但是，有很多说话，和一些行动，以鼓励可再生能源，例如风能，水能，太阳能和所有活的生物体。没有这些排放温室气体，但往往成本将超过煤炭，石油或天然气。
更好，更简单的想法是要记住，最简单的方法，以减少东西是要税，在这种情况下，由征税的碳含量权力。在肮脏的权力，更多的税款，该公司将支付。因此，肮脏的煤炭将更加昂贵比清洁煤，这将看到它的价格上升有关的石油，这将是更昂贵的天然气相比，它就会失去它的一些价格优势，可再生能源。
除非碳税是如此巨大，以在经济瘫痪，它不会删除的价格差距所有可再生能源和化石燃料。但是，如果缩小这一差距，制订不同的环境成本纳入价格-一个有用的原则本身。它还将提供可再生能源生产者强烈的动机，以降低成本，和化石燃料供应商的动机清洁他们的产品。
先例强烈建议，碳税将是有效的。但是，不利碳税是政治问题。经过近十年的努力，欧洲联盟放弃了企图在欧洲碳税去年。德国执政联盟是反对拟议的能源税。在美国，政治家认为，即使提的概念是某些死亡。但是，许多政治上的反对可由如果碳税作了后续的损失在其他地方，比如通过降低工资或销售税。总是有怀疑时，政府想出聪明的新途径，税，这样做是正确的。在针对这一怀疑应该赢得的论点，而不是放弃它。
