⑴ 求一篇關於環境保護的高一英語閱讀理解
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(摩托車) 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(莖) 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
【答案與解析】文章主要講的是人們正採取措施控制和治理沙漠。
1. C。詞彙猜測題。從instead of leaves可知needles是沙漠中植物的葉子，眾所周知沙漠中植物的葉子是針狀的, 再看steel(鋼) 、) branches(樹枝) 、stick(棒) 都不是與葉對應的物體, 只有C項(長在植物莖上的尖的小物體)是「是針狀葉」的意思，故答案選C。
2. B。細節題。從many of the plants even have hard needles instead of leaves可知B項錯誤。
3. A。細節題。從Humans can make deserts, but humans can also prevent their growth(認為可能造成沙漠，但人類也可以防止沙漠的增長)可知答案A正確。
4. D。推斷題。根據常識非洲沙漠遠近聞名, 這說明那裡最需要治理, 作者舉例也會舉典型的, 增加文章的可信度，故答案選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二十億分之一; 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氣是當今世界的主要一次性能源據世界能源委員會統計，已探明的石油、天然氣可采儲量，按 1992 年各國的產量計算，分別只能開采 44 年和 60 年；雖然可采儲量還會有新的發現，但社會需求也有增長，特別是考慮到第三世界國家的經濟發展，油氣燃料可供開採的時間不會很長。在化石燃料中，盡管煤炭的儲量最為豐富，但燃煤造成的嚴重污染使其大不可能成為世界范圍的主要能源。另一方面，核聚變反應可提供清潔的能源，在海洋中蘊藏著約 42 萬億噸核聚變的主要反應物質氘；但核聚變堆研究的難度很大，估計要到下一世紀後期核聚變電站廣泛出現才有可能實現商品化。因此， 在展望 21 世紀能源問題的前景時，可能不得不對油氣資源面臨枯竭、核聚變發電又未能商品化的一段青黃不接時期。為保證這一時期內人類有充足的清潔能源供應，利用太陽能來發電是一種必然的選擇 。
太陽能是最重要的可再生能源，地球上各種能源無不與之密切相關。事實上，太陽在地球的演化、生物的繁衍和人類的發展中，起了無比重要的作用，也為人類提供了取之不盡的能源。太陽內部不斷進行的高溫核聚變反應釋放著功率約為 3. 8 × 1026 瓦的巨大輻射能，其中只有二十億分之一到達至於大氣高層；經過大氣時，約 30% 被反射， 23% 被吸收，僅有一半（約 8 × 1016 瓦）的能量到達地球表面。即使如此，只要能夠利用其萬分之幾，便可滿足今日人類的全部需要。但是，由於其能量密度低，還要受晝夜、季節、氣候、地點等因素的影響，在地面上利用太陽能來發電受到很大限制。為了避免這些缺點，自然要考慮在空間利用太陽能發電的可能性各可行性。
2010 年空間發電可望實用化
空間太陽能發電方式最初是 美國工程師 P.Glaser 首先提出的。其基本構想是在地球的外層空間或月球上建立太陽能衛星發電基地，然後通過微波將電能傳輸到場面的接收裝置，再把微波能束轉變成電能供人類使用 。這一方案的優點是在大氣層外充分利用太陽能，消除了在地面上太陽能密度小而變化大的缺點，無需龐大的儲能裝置，既減少佔地，又節約大量設備投資。可以預計，隨著光電轉化材料和運載等方面技術的進步，太陽能空間發電的成本將大大降低。
這一設想提出後，受到了各國的重視。 1977 年 —1980 年美國能源部和航天航空局組織對空間太陽發電的概念進行研究，認為其實施不存在不可克服的技術困難。當時設計了一種稱為「參考系」的發電系統；由 60 地太陽能面板組成，每塊長 10 公里，寬 5 公里，發電 500 萬千瓦，總發電量為 3 億千瓦。用這樣一顆發電衛星，便可取代美國所有的地面電站。由於該系統過於龐大，約需 3000 千億美元的巨資投資，在當時冷戰的條件下難以得到支持。隨著能源問題的突出各航天技術的進步， 1995 年美國航天航空局成立研究組，重新審視這一問題，較全面地分析了空間太陽能發電的技術經濟可行性，在方案上也有很大不同：採用漸進的自我發展模式，即先發射一顆投資為 100—150 億美元的 25 萬千瓦發電衛星，出售電力以回收投資並獲取利潤，然後再擴大發電衛星的規模。該研究組估計， 2010 年以後，空間發電將實用化。目前，其他一些國家和國際組織也在進行太陽能空間發電方面的工作。

請記住全球變暖？早在12月，氣候變化的威脅是雷鳴般的和富有的國家同意削減其二氧化碳和其他溫室有關的排放量。自那時以來，興趣明顯降溫，和許多歐洲國家已經在運行遠離作出的承諾，使他們大聲幾個月前。但是，有很多說話，和一些行動，以鼓勵可再生能源，例如風能，水能，太陽能和所有活的生物體。沒有這些排放溫室氣體，但往往成本將超過煤炭，石油或天然氣。
更好，更簡單的想法是要記住，最簡單的方法，以減少東西是要稅，在這種情況下，由征稅的碳含量權力。在骯臟的權力，更多的稅款，該公司將支付。因此，骯臟的煤炭將更加昂貴比清潔煤，這將看到它的價格上升有關的石油，這將是更昂貴的天然氣相比，它就會失去它的一些價格優勢，可再生能源。
除非碳稅是如此巨大，以在經濟癱瘓，它不會刪除的價格差距所有可再生能源和化石燃料。但是，如果縮小這一差距，制訂不同的環境成本納入價格-一個有用的原則本身。它還將提供可再生能源生產者強烈的動機，以降低成本，和化石燃料供應商的動機清潔他們的產品。
先例強烈建議，碳稅將是有效的。但是，不利碳稅是政治問題。經過近十年的努力，歐洲聯盟放棄了企圖在歐洲碳稅去年。德國執政聯盟是反對擬議的能源稅。在美國，政治家認為，即使提的概念是某些死亡。但是，許多政治上的反對可由如果碳稅作了後續的損失在其他地方，比如通過降低工資或銷售稅。總是有懷疑時，政府想出聰明的新途徑，稅，這樣做是正確的。在針對這一懷疑應該贏得的論點，而不是放棄它。
