They want to bring water to the deserts, so people can live and grow food. They are learning a lot about the deserts. But more and more earth is becoming deserts all the time. Scientists may not be able to change the deserts. Scientists think that people make deserts. People are doing bad things to the earth.Some places on the earth dont get very much rain. But they still dont become deserts. This is because some green plants are growing there. Small green plants and grass are very helpful to dry places. Plants dont let the hot sun make the earth even drier. Plants dont let the wind blow the earth away. When a little bit of rain falls, the plants hold the water. Without plants, the land can become a desert much more easily.文章大意：由于土地沙漠化，农田面积在减少，如何使沙漠变良田，植被作用至关重要。科学家们正在为此努力。56Small green plants are very important to dry places because _.Athey dont let the sun make the earth even drierBthey dont let the wind blow the earth awayCthey hold the waterDall of the above答案：D细节理解题。由原文第二段内容可知，A、B、C三项均可，所以选择D项。all of the above表示“以上所有的(选项)”。57Which is the main idea of the first paragraph?AScientists know how to change deserts into good land.BLand is becoming deserts faster than scientists can change it back into good land.CIf scientists can bring water to deserts, people can live and grow food there.DMore and more places are becoming deserts all the time.答案：B段落大意题。由第一段和现实可知，土地沙漠化的速度要比科学家尽力使沙漠变良田的速度快，B项完整。其他三个选项都很片面，不能概括整个段落的含义。58After reading this passage, we learn that _.Aplants can keep dry land from becoming desertsBit is good to get rid of the grass in the desertsCall places without much rain will become desertsDit is better to grow crops on dry land than to grow grass答案：A推理判断题。由文章可知，植被对控制土地沙漠化起主要的作用，A项正确。其他三个选项不符合文意。BCan better food create better people? This is the true idea that is driving the development of todays farming quickly.The future food is the best food. Scientists will put realtime sensors into our bodies that can read the information of what our bodies need. A personal health system will be able to study the information that the sensor provides before making a food order. Then the order will go to the local food supplier，who will get in touch with the food maker on the farm. The entire supply will be controlled by computer according to the needs of the end user. Food from restaurants will come in over a million kinds. Customers will be able to order the food that is really good for their health.By 2050, a farm will use technologies that will leave todays farming far behind. A farm, as shown by Despommier, a farming scientist，will be a 30storeytall building and used to grow plants without soil. The farms of the future will grow halfplant, halfanimal products, and people will be able to control nature. Special crops will be grown in this controlled special space, such as short stalk corn, personalized fruits and vegetables.Besides growing food, new ways will be found to “grow” products. We will also be able to control plants in other ways. For example, we will some day be able to “train” a tree to grow its branches into the shape of tables, coffee tables, chairs, or rocking chairs. Once these unusual branches are fully grown，farmers can walk up to the tree and harvest the rocking chairs by cutting them off, which is the same as harvesting apples or pears.The entire production area in the future will be managed by a robot that travels up and down doing all the necessary jobs of planting, weeding, watering, and harvesting.59The realtime sensors in our bodies will find out _.Awhat we like and what we hateBwhether we are healthy or notChow much food we needDwhat food our bodies need答案：D细节理解题。根据第二段“The future food is the best food.Scientists will put realtime sensors into our bodies that can read the information of what our bodies need.”可知应选D项。60The food order goes to the local food supplier so that _.Athe needs of the end user will be well metBthe food supplier will not waste any moneyCthe food maker will know how to grow plantsDthe food supplier will know what healthy food is答案：A细节理解题。根据第二段“Then the order will go to the local food supplier. according to the needs of the end user.”可知需要什么食物的信息最终传递到食物生产者那儿，目的是满足最终用户的需要。故选A项。61What can we infer from Paragraph 3?ACrops will take longer to grow by 2050.BIn the future，there will be no animal products.CCrops in the future will be very different from todays.DCrops in the future will grow without sunshine, water, or soil.答案：C推理判断题。根据第三段的首句和最后两句可推断未来的农作物和我们现在农场的农作物会有很大的不同。62What does the example of producing chairs on trees show?ANo furniture will be made.BHumans can control plants.CTrees can produce everything.DFruit will be in the shape of tables.答案：B推理判断题。根据第四段第二句“We will also be able to control plants in other ways.”及后面的举例可知，那个例子是用来表明我们可以控制植物的。CNearly all our food comes from the soil. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter(粪) from animals also falls on it.All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals waste is the best food for the soil, but chemical fertilizers(化肥) are also very useful. The same crop should not be grown in the same place every year; its better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.文章大意：本文为议论文，文章认为几乎所有的食物都来自土壤，而土壤同样需要食物，并对此给出了重要的见解。63What would happen first without plants?APeople would have more crops.BAnimals would die.CThere would be more food.DThere would be less soil.答案：B细节理解题。由第一段第三句“If there were no plants，we would have no animals and no meat.”可知如果没有了植物，我们就没有了动物和肉类，B项符合语境。64What does the writer tell us in the first paragraph?ALeaves, plants, grass and waste live on each other.BThere would be no animals without meat.CThere would be no plants without animals.DPeople, animals, plants and soil live on each other.答案：D段落大意题。第一段主要讲人、动物、植物和土壤的生存彼此依赖，互相联系，故选D。65Which is the best food for soil in the field?AChemical fertilizers. BPlants and grass.CAnimals waste. DDifferent crops.答案：C细节理解题。由第二段第三句“Farmers found that animals waste is the best food for the soil.”可知选C。66Why do we often grow a different crop in the same place every year?ABecause we can keep the soil rich this way.BBecause we dont have enough land.CBecause we want to have a different food.DBecause we do this as a habit.答案：A细节理解题。由第二段最后一句“A change of crop and the use of a good fertilizer will keep the land good.”可知本题答案为A。DOrganic food is very popular. It is also expensive. Some organic food costs twice as much as nonorganic food. Some parents and pet owners pay up to 200 percent more for organic food while some people think organic food is a waste of money.There is one main difference between organic and nonorganic food. Organic farms do not use agricultural chemicals, such as pesticides(杀虫剂). This guarantees that the products are natural.Some people think “organic” means “locally grown”. Originally this was true. Over time organic farming became more difficult. The demand for organic food grew larger than the supply. Small companies had to sell out to large companies. There werent enough organic materials. This made it difficult for many organic companies to stay in business. Today, many large companies have an organic line of products.Is organic food more nutritious(有营养的)? This is part of the debate. Many farmers and consumers(消费者) believe it is. They think agricultural chemicals cause health problems such as cancer. Many health professionals disagree. Few studies prove that organic food prevents health problems. Health specialists worry more about bacteria. These can come into contact with organic and nonorganic food. Doctors recommend washing produce very carefully. Most people agree that naturallygrown food tastes better. Is tastier food worth the extra money? This is a matter of opinion. Whether it is healthier or not may require more research. However, organic food consumers argue it is better to be safe than sorry.文章大意：文章分段讨论了人们在有机食物的价格、有机食物是否更有营养等方面持有的不同观点。67It can be inferred from the passage that _.Aorganic farming is better for the environmentBorganic food is healthier than nonorganic foodCthe author believes organic food is more nutritiousDparents often complain about the high prices of organic food答案：A推理判断题。根据第二段第二句中的“Organic farms do not use agricultural chemicals”可以推断，有机耕作相对来说更环保。68What does the author point out in Paragraph 3?AMost organic food is locally grown nowadays.BOrganic farming once experienced a difficult period.COrganic food tastes better than nonorganic food.DOrganic companies find it difficult to earn money.答案：B细节理解题。根据第三段第三句到第七句可知，有机原料不足，小型的有机农场被迫转让给大型的有机农场。有机农业在发展过程中经历过一段困难时期。69What can we learn from the passage about health experts?AThey believe organic food prevents health problems.BThey consider organic food a waste of money.CThey dont share many consumers views.DThey recommend eating organic food.答案：C细节理解题。根据倒数第二段可知，许多消费者认为有机食物更有营养，但许多健康专家不同意这一观点，所以选C项。70In many consumers opinion, organic food is better for the following reasons EXCEPT _.Abeing healthierBbeing more beautifulCbeing tastierDbeing more nutritious答案：B细节理解题。根据最后两段可知，乐于购买有机食物的消费者认为有机食物更有益健康、更富含营养成分、更美味，文章并没有提到有机食物的外形问题，因此选择B项。EInvesting(投资) in agricultural research and development can help poor countries fight hunger and poverty. A new study says investments in subSaharan Africa increased by more than twenty percent between 2001 and 2008. However, the study also found that just a few countries were responsible for most of that growth. Nigeria was responsible for onethird of it. Ghana, Tanzania, Sudan and Uganda also increased their spending, but 13 countries reduced their investments.Nienke Beintema from the Washingtonbased International Food Policy Research Institute led the study. She says new technologies are needed to deal with some of the causes of hunger. She said, “Changes in food price, growing population, water shortage and climate change create the demand for better technologies or different technologies to address these issues.” She says some countries, including Nigeria, have enhanced their investments after spending far too little in the past.Nigeria now has the largest agricultural research system south of the Sahara. That is one measure of progress. But Nienke Beintema says a better measure is that a country spends more than one percent of its agricultural money on research. And in 2008, she says, Nigeria was not doing that. Botswana, Burundi, Kenya, Mauritania and Mauritius were spending more than one percent. So were Namibia, South Africa and Uganda.Ms Bientema examined levels of financing and employment at 370 research centers in 32 countries. She believes most countries depend too heavily on international donations to help pay for research. Many donations are shortterm, she says, and the research often ends when the money has been spent.Ms Bientema says countries must improve their higher education systems to turn out more qualified researchers. But the study has found that new researchers are not being hired in some countries because of budget (预算) problems. At the same time, many older researchers are nearing retirement age.文章大意：非洲很多国家在
