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

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

Charter schools operate with public money but without many of the rues that Sovem tradi-tional public schools．In the Uruted States the rules for charter schools difFer from state to state． But in Seneral these schools havegreater freedom to decide what to teach and how to teach it．
The "charter 'is a perfarmance contract．It establishes thegoals of the school and other details like how student performance will be measured． Forty - seven million students attend traditional public schools．But more than a million students attend charter schools:
And now a group of charter schools have formed the Green Charter Schools Network.The idea is to have environmentally friendly school buildings but toalso go further than that．The schools teach students to become involved in community issues that affect them and the environ-ment． For example, youg children grow crops in a school garden and leam about healthy eat-ing．Older students help recycle waste from the cafeteria．And local schoois share what they grow in community gardens with people in need．
Jim McGrath is president．of the Green Charter Schools Network． He says there are about 200 "green" charter schools across the United States． He says the plan is to also include tradi-tional public schools as well as private schools．
Jim McGrath: "The most important thing is that every one of us - every child, every adult - has a reaponsibility that their action, every action we make has an effect on the earth that we live in． And that our natuntl resources are not unlimited． And that if we want a positive earth for future generations, we all need to make comnutments to be agents of change so that we don' t destroy our natural resources．
The Green Clarter Schools Network holds its first national conference this October in Min- nesota．It will include companies and orgaizations like Waste Management and the Uruted States Green Brulding Council． We sincerely hope that their goal is to expand the movement across the country．

If you have a bottle of water recycled from urine(尿), would you drink it? Astronauts at the ISS may soon do so.
NASA（美国航空航天局）said it would see a high-tech machine to recycle wastewater at the ISS. The machine will recycle water for washing hands, shower water, water for brushing teeth and even urine to make drinking water. It will save millions of dollars each year.
At present, each ISS astronaut uses about 4.4 liters of water every day. It costs about 24 million dollars a year to send water up to the ISS. A liter of water costs about $11,000.
The machine will be sent to the ISS later. NASA hopes it will recycle about 93% of all the water used on the station.
Will the water be clean? Different chemicals will be put in the wastewater. The water will be heated to 130℃ to kill bacteria. Scientists say that the recycled water is thousands of times better than the water from a city tap(水龙头).
