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．

A Book Review — The Snake-Stone by Berlie Doherty
The setting: Urban England (the cities), but also rural England (the countryside) including remote English villages.
The theme: The main theme is a teenage search of self-discovery, in this case the search for a mother from whom the hero was separated at an early age. Its other concerns are love, getting on with others, being persistent and courageous and trying to deal with doubts, troubles and worries. As the book moves to a close, James' swimming coach says to him: "You are not like a kid obeying instructions any more. You are diving like a young man who knows where he is going."
The characters: James is the hero of the story. He is a championship diver, and has a comfortable life with his foster parents (养父母). Yet he also has the qualities to take him on a long journey to find his birth mother. The other characters in The Snake-Stone, James' parents, his diving instructor, best friend, the villagers, people he meets on his journey, are pictured realistically.
The turning point: The turning point in the story comes while James' foster parents are away in London, and he wonders about the identity of his birth mother. The only clue he has is a fossil, "the snake stone" which she left behind along with a note on which she had written: "Take good care of Sammie. It was written on a torn envelope with parts of an address still there.
The journey: Instead of going to London, James decides to find his birth mother. With help from his geography teacher, James sets out for the remote country village where his mother might be found. James has painful, challenging, but also humorous and happy travels. The mother he finally meets, Anne, has a minor yet powerful voice in the novel. He comes to understand why she left him at a stranger's door fifteen years before. Although the meeting is not long, it leaves him with a feeling of completeness.

The Chinese word “Shanzhai” means a small mountain village, but now it becomes an accepted name for fakes (假货), after “Shanzhai Cell-phones” produced by small workshops in southern China became popular in the mainland market over the past two years.
Besides “Shanzhai” electronic products, there are “Shanzhai” movies, “Shanzhai” stars and even a “Shanzhai” Spring Festival Gala (联欢晚会), a copy of the 25-year-old traditional show presented by CCTV on Chinese Lunar New Year’s Eve.
“Shanzhai” has become a culture of its own, meaning anything that imitates something famous.
In Chongqing, “Shanzhai” version “Bird’s Nest” and “Water Cube” woven by farmers with bamboo attract wide attention from tourists. Both are copies of the famous Olympic buildings in Beijing.
A literature critic said that taking the “Shanzhai” Gala as an example, when the traditional CCTV program becomes less and less attractive to the audience, the“Shanzhai” version appears timely to attract people. “Although it is often connected with poor techniques and operation, ‘Shanzhai’ culture meets the psychological needs of common people and could be a comfort to their minds,” he said.
To the mainstream (主流的) culture, the rise of “Shanzhai” culture is a challenge and a motivation (动力). People believe different kinds of cultures developing together is a perfect situation and it is for the public to choose.The Chinese word “Shanzhai” may have started with ______.
| A．Spring Festival Gala | B．electronic products |
| C．fake cell-phones | D．Olympic buildings |
According to the passage, “Shanzhai” culture refers to ______.
| A．the action that a person imitates famous people |
| B．products with poor techniques and quality |
| C．those similar names to famous brands |
| D．anything that imitates something famous |
We can infer that the mainstream culture ______.
| A．may develop faster because of the challenge of “Shanzhai” culture |
| B．is the challenge of “Shanzhai” culture |
| C．will be replaced by “Shanzhai” culture |
| D．is held back by “Shanzhai” culture |
For most of us, the rain that falls on our roof runs off into the ground or the sewer(下水道) system. But if you want to save a little water and reuse it on your lawns or plants --- or even use it for laundry, dishes, or other needs --- collecting rainwater from your gutter’s downspouts(檐槽的水落管) is a no-brainer.
According to John C. Davis, writing in E / The Environmental Magazine, just about any homeowner can collect rainwater, given that the roof and gutters do most of the work. And since an inch of rain falling on a 2,000-square-foot roof produces some 1,200 gallons of water, you can harvest enough to water your lawn or garden.
Plants and grass actually do better when fed rainwater instead of tap water, which is usually treated with substances that can hold back plant growth. Using rainwater can also extend the life of pipes, since the salts added to tap water may gradually damage the pipes. However, homeowners should set up a water purification system if they do plan to use rainwater for inside needs.
Rainwater harvesting can also be good for the local community, as it reduces the erosion, flooding, and pollution associated with heavy rainfall, and reduces dependence on public water supplies. So some states fund rainwater collection systems in their local communities.
Many varieties of rain barrel(桶) systems, starting at just $100, are available for home use. A typical setup is simply a rain barrel positioned under a gutter’s downspout. Skillful homeowners can make their own water harvesting systems, but buying one is a lot easier. Most garden centres offer a range of choices as well as tips.The underlined word “no-brainer” in Para. 1 probably means something that ______.
| A．is hard to deal with | B．is very easy |
| C．is of no real value | D．deserves more attention |
From Paragraphs 3 and 4, we can learn _______.
| A．how to set up a water harvesting system | B．how a rain barrel system works |
| C．some advice on saving tap water | D．the benefits of using rainwater |
What is the topic of the passage ?
| A．Basic gardening skills. | B．Water-saving techniques. |
| C．Wastewater treatment systems. | D．Roof rainwater collection. |
A serious problem for today's society is who should be responsible for our elderly and how to improve their lives. It is not only a financial problem but also a question of the system we want for our society. I would like to suggest several possible solutions to this problem.
First, employers should take the responsibility for their retired employees. To make this possible, a percentage of profits should be set aside for this purpose. But when a company must take life-long responsibility for its employees, it may suffer from a commercial disadvantage due to higher employee costs.
Another way of solving the problem is to return the responsibility to the individual. This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to step in to care for the poor.
In addition, the government could take responsibility for the care of the elderly. This could be financed through government taxes to increase the level of pensions. Furthermore, some institutions should be created for senior citizens, which can help provide a comfortable life for them. Unfortunately, as the present situation in our country shows, this is not a truly viable answer. The government can seldom afford to care for the elderly, particularly when it is busy trying to care for the young.
One further solution is that the government or social organizations establish some working places especially for the elderly where they are independent.
To sum up, all these options have advantages and disadvantages. Therefore, it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations.What is the passage mainly about?
| A．The problems faced by the old in society. |
| B．Why we should take responsibility for the old. |
| C．How we can improve the lives of the old. |
| D．Where the old can go to get their pensions. |
The underlined word "viable" most probably means"".
| A．impossible | B．practical | C．useful | D．important |
What is the writer's main purpose in writing this article?
| A．To point out the need for government support for old people. |
| B．To make general readers aware of the problems of retired people. |
| C．To discuss some possible solutions to an important social problem. |
| D．To instruct retired people on how they can have a happier life. |
The text is most likely to be found in a book about____.
| A．social science | B．historical events |
| C．political problem | D．political systems |
