参考解析
解析：根据第一段“The Sahara Desert is an unfriendly environment. During the day it's very hot, and at night it's sometimes very cold.”可知，撒哈拉沙漠不适宜居住的原因是其极端的天气。故本题选A。
由于撒哈拉沙漠极端的天气和缺水因素，跑过撒哈拉沙漠的4, 300英里很显然是一种挑战。故本题选C。
根据第三段的“Every morning they began running at 5:00.”可知，文中的三个人每天早晨5点开始跑步。故C正确。他们是从上午11点到下午5点之间停下来休息，这是一个长时间的休息，故A和B错误。休息后他们继续跑到晚上9:30，故D错误。
由最后一段的“...successfully finished their trip across the Sahara Desert. They hugged each other and put their hands in the water of the Red Sea.”知道，A项正确。
最后一段提到，很多时候，他们想放弃跑步回家，但他们没有放弃。因此，他们成功跑过撒哈拉沙漠的原因是：从不放弃。故D项正确。

共用题干第三篇Only special plants can survive in the terrible climate of a desert,for these are regions where the annual range of the soil temperature can be over 75℃.Furthermore,during the summer there are few clouds in the sky to protect plants from the sun's ray.Another problem is the fact that there are frequently strong winds which drive small-sharp particles of sand into the plants,tearing and damaging them.The most difficult problem for all forms of plant life,however,is the fact that the entire annual rainfall occurs during a few days or weeks in spring.Grasses and flowers in desert survive from one year to the next by existing through the long, hot,dry season in the form of seeds.These seeds remain inactive unless the right amount of rain falls.If no rain falls,or if insufficient rain falls,they wait until the next year,or even still the next.Another factor that helps these plants to survive is the fact that their life cycles are short.By the time that the water from the spring rains disappears—ust a few weeks after it falls一such plants no longer need any.The perennials（多年生植物）have special features which enable them to survive as plants for several years. Thus,nearly all desert perennials have extensive root systems below ground and a small shoot system above ground.The large root network enables the plant to absorb as much water as possible in a short time.The small shoot system,on the other hand,considerably limits water loss by evaporation（蒸发）.Another feature of many desert perennials is that after the rainy season they lose their leaves in preparation for the long,dry season,just as trees in wetter climates lose theirs in preparation for the winter. This reduces their water loss by evaporation during the dry season.Then,in the next rainy season,they come fully alive once more,and grow new branches,leaves and flowers,just as the grasses and flowers in desert do.We can learn from the passage that the shoot system of the perennials_________.A:can help the perennials absorb less of the sun's rayB:decides the appearance of the perennials in desertC:limits the function of the perennials' branchesD:may prevent the perennials from losing much water

Deforestation and Desertification(沙漠化) The Sahel zone lies between the Sahara desert and the fertile savannahs(热带大草原)of northern Nigeria and South Sudan. The word sahel comes from Arabic and means marginal or transitional ,and this is a good description of the semi-arid(半干旱) lands, which occupy much of the Western African countries of Mail, Mauritania, Niger ,and Chad. Unfortunately, over the last century the Sahara desert has steadily crept southwards eating into once productive Sahel lands. United Nations surveys show that over 70 percent of the dry land in agriculture use in Africa has deteriorate dover the last 30 years. Droughts have become more severe, the most recent lasting over twenty years in parts of the Sahel region. The same process of desertification is taking place across southern Africa as the Kalahari desert advances into Botswana and parts of South Africa. One of the major causes of this desert advance is poor agricultural land use, driven by the pressures of increasing population. Overgrazing一 keeping too many farm animals on the land一means that grasses and other plants cannot recover, and scarce water supplies are exhausted. Over cultivation一 trying to grow too many crops on poor land一 results in the soil becoming even less fertile and drier, and beginning to break up. Soil erosion (侵蚀) follows, and the land turns into desert. Another cause of desertification is loss of tree cover. Trees are cut down for use as fuel and to clear land for agricultural use. Tree roots help to bind the soil together, to conserve moisture, and to provide a habitat for her plants and animals. When trees are cut down, the soil begins to dry and loosen, wind and rain erosion increase, other plant species die, and eventually the fertile top soil may be almost entirely lost, leaving only bare rock and dust. The effects of loss of topsoil and increased drought are irreversible. They are, however, preventable. Careful conservation of tree cover and sustainable agricultural land use have been shown to halt deterioration of soils and lessen the effects of shortage of rainfall. One project in Kita in south-west Malifunded by UNDP has involved local communities in sustainable management offorest, while at the same time providing a viable(有活力的)agricultural economy. This may be a model for similar projects in other West African countries.文章{1~5)The Sahel zone is an area which _____.A.is covered with sad and grassB.has a long historyC.occupies much of South NigeriaD.belongs to Sudan

The Sahara【撒哈拉沙漠】 The name Sahara derives from the Arabic word for “desert” or “steppe”. At 3. 5 million square miles, an area roughly the size of the United States, the Sahara Desert in northern Africa is the largest desert in the world. It spans the continent from the Atlantic Ocean to the Red Sea. Daytime temperatures can reach as high as 130°F. The humidity sometimes gets into the teens. But it can also be as low as 2.5 percent, the lowest in the world. Most of the Sahara receives less than five inches of rain per year, while large areas sometimes have no rainfall at all for years. At the heart of the Sahara is the landlocked north African country of Niger. Here the sand dunes can be 100 feet tall and several miles long. Here sand plains stretch over an area larger than Germany where there is neither water nor towns. Yet sitting in the midst of the surrounding desert is the town of Bilma. Suddenly there are pools of clear water. Surprisingly, there are groves of date palms. Underground water resources, or oases, sufficient to support irrigated agriculture are found in dry stream beds and depressions. Irrigation ditches run off a creek to water fields. Corn, cassava, tea, peanuts, hot peppers, and orange, lime, and grapefruit trees grow in these fields. Donkeys and goats graze on green grass. The Sahara of Niger is still a region where you can see a camel caravan of 500 camels tied together in loose lines as long as a mile, traveling toward such oasis towns. There a caravan will collect life-sustaining salt, which is mined from watery basins, and transport it up to 400 miles back to settlements on the edges of the desert. The round trip across the vast sands takes one month.文章(36~40)This passage is mostly about________.A) life in the Sahara B) the deserts of AfricaC) BilmaD) how camels travel in the desert

共用题干第三篇The SaharaThe name Sahara derives from the Arabic word for"desert"or"steppe".At 3.5 million square miles, an area roughly the size of the United States,the Sahara Desert in northern Africa is the largest desert in the world.It spans the continent from the Atlantic Ocean to the Red Sea.Daytime temperatures can reach as high as 130°F.The humidity sometimes gets into the teens.But it can also be as low as 2.5 percent,the lowest in the world.Most of the Sahara receives less than five inches of rain per year,while large areas sometimes haveno rainfall at all for years.At the heart of the Sahara is the landlocked north African country of Niger. Here the sand dunes can be 100 feet tall and several miles long.Here sand plains stretch over an area larger than Germany where there is neither water nor towns.Yet sitting in the midst of the surrounding desert is the town of Bilma. Suddenly there are pools of clear water. Surprisingly,there are groves of date palms.Underground water resources,or oases, sufficient to support irrigated agriculture are found in dry stream beds and depressions.Irrigation ditches run off a creek to water fields.Corn,cassava,tea,peanuts,hot peppers,and orange,lime,and grapefruit trees grow in these fields.Donkeys and goats graze on green grass.The Sahara of Niger is still a region where you can see a camel caravan of 500 camels tied together in loose lines as long as a mile,traveling toward such oasis towns.There a caravan will collect life-sustainingsalt,which is mined from watery basins,and transport it up to 400 miles back to settlements on the edges of the desert.The round trip across the vast sands takes one month.The Sahara can be described as_______.A:a place of contrastsB:a place where no one livesC:an area where the winters are coldD:an area that appeals to many tourists
