C
A new study in West Africa shows how farm irrigationsystems powered by the sun can pro-duce more food and money for villagers. The study-in Benin found that solar - powered pumpsare effective in 8upplying water, especially during the long dry season.
Sub - Saharan Africa is the part of the world with the least food security. The United Na-tions Food and Agriculture Organization estimates that more"than one biillion of the world" s peo-ple faced hunger last year.Around 265 million of them live"south of the Sahara Desert: Lack of rainfallis one oftheir main causes offood shortages..
Jennifer Bumey from Stanford University in Califomia led the study.The research team helped build three solar - powered drip irrigation -(滴灌) ,systems in northem Benin. Between 30 and 35 women used each system to pump water from the ground or a stream.Each woman was responsible for farming her own 120 sqrurre meters of land. They also farmed other land collectively.
The solar - powered irrigation systems produced an average of nearly two tons of vegetables per montb. During the first year, the women.kept a monthly average of almost rune kilograms of vegetables for home use.They sold the surplus produce at local markets. The eamings greatly increased their ability to buy food during the dry season which can last six to nine months. Peo- ple in the"two villages with the systems were able to eat three to five more servingsof yegetables per day.But making the surplus available at markets also had a wider effect.
The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets. The amount of vegetables eaten in those villages also increased, though not as much.The researchers note that only four percent of the croplamd in sub - Saharan Africa is irrigated. Using solar power to pump water has higher costs at first. But the study says it can be more economical in the long term than using fuels like gasoline, diesel or kerosene. And solar power is environmentally friendly.
66.Food security in Sub - Saharan Africa is insufficient mainly because of
A.lack of rainfall B.limitation of farmland
C. a small crop variety D.little sunlight
67.From the third paragraph we know that _______.
A.water is wasted by using the system
B. the farmers imgate the land together
C. all farmers use irrigation systems in northem Benin
D. the solar - powered systems take up more manpower
68.The underlined word "surplus" in the 4th paragraph most probably means_______
A.special B.unnecessary C.extra D.abandoned
69.Usinf.solar power to pump water has advantages EXCEPT that
A.solar energy has higher cost at first
B.solar power helps to protect environment
C.solar power helps farmers increase eanungs
D. solar energy can be more economical in the long run
70.What can be the best title for the text?
A.Manpower affects rainfallin Africa
B.Irrigation by carrying water in buckets
C.Solar - powered pumps aid African farmers
D.Vegetable supply increased in African villages

Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep a problem that couldn’t be solved the night before can often appear more manageable, although the evidence(证据)until now has been personal experience. But researchers at the University of Luebek in Germany have designed an experiment that shows a good night’s sleep can improve insight(洞察力)and problem-solving.
“If you have some newly-got memories in your brain, sleep acts on these memories and rebuild them, so that after sleep the insight into problem which you could not solve before increases,” said Dr Jan Born, a neuroscientist(神经病学专家)at the university. To test the theory, they taught volunteers two simple rules to help them turn some numbers into a new order.There was also a third,hidden rule,which could help them increase their speed in solving the problem.The researchers divided the volunteers into two groups:half were allowed to sleep after the training while the rest were forced to stay awake.Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group.“Sleep helped,”Born said in a telephone interview.“The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep,so it can act on the problem.”But Born admitted that he and his team don’t know how rebuilding of memories occurs or what governs it.Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestions that sleep can help develop creative thinking.Although the role of sleep in human creativity will still be a mystery,the research gives people good reason to fully respect their periods of sleep,they added.
60.The underlined phrase“sleep on it”in Paragraph 1 probably means_________.
A.to delay deciding something until the next day
B.to get as much sleep as possible
C.to go on sleeping without being disturbed
D.to sleep till after the time you usually get up in the morning
61.Jan Born and his team carried out the experiment through________.
A.comparison B.interview C.survey D.imagination
62.It can be inferred from the passage that___________.
A.people should sleep so long as they have time
B.sleep is the only way to solve hard problems
C.people have various periods of sleep D.people know how sleep rebuilds memories
63.What would be the best title for the passage?
A.How Sleep Works. B.Sleep Helps Solve Problems.
C.No Evidence,But Well Founded. D.Born’s Discovery on Sleep.

What does an astronaut eat in space? This is a question that will puzzle many, as people rarely think of that. In the early space-travel years, astronauts ate dehydrated (脱水的) foods that were eaten through straws (吸管). In today’s space-age, the food that they eat is totally different. They eat food in the same way as people do on Earth.
Astronauts are able to prepare and eat a variety of foods in space. Some can be eaten in their natural form, like fruits, while some need to add water, like noodles. However, there are no refrigerators, so the food has to be prepared and eaten without being stored for a long time. When the astronauts are hungry, they simply eat the food by opening the food packages and with a fork, knife, and spoon.
Just like people on Earth, astronauts also eat three meals a day which include breakfast, lunch and dinner. Sometimes they also eat snacks. The US space agency NASA has found out that an astronaut’s diet reduces by about 70% on a space mission, though he has a wide range of foods to choose from like nuts, chicken, beef, seafood, and candies. Drinks in the spaceship include coffee, tea, juices, and lemonade.
Astronauts can also request a particular food that they would like to have in space. Scientists are always experimenting and trying out different space foods that can be offered to astronauts when on space missions.
45. Now astronauts eat ________ in space.
A. dehydrated (脱水的) foods B. food as people do on Earth
C. totally different D. food with a lot of water
46. The food the astronauts prepared ________ .
A. can’t be stored for a long time B. can be put into refrigerators
C. can be stored for a long time D. can’t be kept in the food packages
47. In space, astronauts ________ like people on Earth.
A. only have nuts, chicken and beef B. onlyhave lunch for a day
C. only drink coffee, tea and lemonade D. also eat three meals a day
48. What are scientists experimenting and trying out?
A. Some very special snacks. B. How astronauts can sleep well.
C. Different space foods for astronauts. D. How to get some fruits for astronauts.

Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment(营养). The old saying "An apple a day keeps the doctor away. " is not as silly as some people think. The body needs fruit and vegetables because they contain vitamin C. Many people take extra vitamins in pill form(丸剂), believing that these will make them healthy. But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn"t need or use extra vitamins, so why waste money on them?
In the modem western world, many people are too busy to bother about eating properly. They throw away the good habits and throw anything into their stomachs, eating hurriedly and carelessly. The list of illnesses caused or made worse by bad eating habits is frightening.

Organic food has no nutritional or health benefits over ordinary food,according to a major study.
Researchers from the London School of Hygiene & Tropical Medicine said consumers were paying higher prices for organic food because of its imagined health benefits,creating a global organic market worth an estimated $48 billion in 2007.
A systematic review of 162 scientific papers published in the scientific literature over the last 50 years,however,found there was no significant difference.
“A small number of differences in nutrient content were found to exist between organically and conventionally(通常)produced foodstuffs,but these have nothing to do with public health,” said Alan Dangour ,one of the report"s authors.
“Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority .”
The results of research,which was commissioned by the British government’s Food Standards Agency,were published in the American Journal of Clinical Nutrition.
Sales of organic food have fallen in some markets,including Britain,as a slowdown in economic growth has led consumers to cut back on purchases.
The Soil Association said that growth in sales of organic products in Britain slowed to just 1.7percent,well below the average annual growth rate of 26 percent over the last decade.
64. Why does organic food cost more than conventionally produced food?
A. Because people think they are much healthier. B. Because they are more delicious.
C. Because people prefer organic food. D. Because they sell better.
65. According to the study,organic food is_________ than conventionally produced food.
A. much healthier B. better C. no healthier D. less healthier
66. Sales of organic food have fallen because of___________.
A. high price B. economic decline C. bad service D. poor quality
67. Where can you find this passage in a newspaper?
A. Economy B. Science. C. Food & Nutrition D. Fashion
