A new study in West Africa shows how farm irrigation systems powered by the sun can produce more food and money for villagers. The study in Benin found that solar-powered pumps are effective in supplying water, especially during the long dry season.
Sub-Saharan Africa is the part of the world with the least food security. The United Nations Food and Agriculture Organization estimates that more than one billion of the world’s people faced hunger last year. Around two hundred sixty-five million of them live south of the Sahara Desert. Lack of rainfall is one of their main causes of food shortages.
Jennifer Burney from Stanford University in California led the study. The research team helped build three solar-powered irrigation systems in northern Benin.
The solar-powered irrigation systems produced an average of nearly two metric tons of vegetables per month.
They sold the surplus(过剩的) produce at local markets. The earnings greatly increased their ability to buy food during the dry season which can last six to nine months.
People in the two villages with the systems were able to eat three to five more serving of vegetables 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 cropland 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. people in South Africa will soon be provided with enough food
B. the demand for fuels like gasoline will greatly decrease in Africa
C. people in sub-Saharan Africa don’t take agriculture seriously
D. it’s worthwhile to use the new irrigation systems on the while
4. People in the two villages owe all the following to Jennifer’s irrigation systems EXCEPT that ______.
A. they could buy more food during the dry season

A high school history teacher once told us, “If you make one close friend in school, you will be most fortunate. A 21 friend is someone who stays with you for life”. 22 teaches that he was right. Good friendship is just not easily 23.
It is possible that we simply do not stay in one place 24 enough for true friendship to develop. However, there can be 25 disagreement on the need for each of us to think carefully about the kind of friendship we want.
To most of us, friendships are considered very important, 26 we need to have it clear in our minds the kinds of friendship we want. Are they to be close or 27 at arm’s length? Do we want to 28 ourselves or do we want to walk on the surface? For some people, many friendships on the surface are 29 enough. And that’s all right. But at some 30 we need to make sure that our expectations are the same as our friends’ expectations. The sharing of personal experience including our tears as well as our dark 31 is the surest way to deepen friendships. But it must 32 slowly and carried on only if there are 33 of interest and action in return.
What are some of the 34 of our friendship? The greatest is to 35 too much too soon. Deep relationships 36 time. Another “major difficulty” is the selfishness to think one “possesses” the other, including his time and attention. 37 , friendships require actions in return. In other words, you must 38 as much as you take. Finally there is a question of taking care of. Unless you spend 39 time together, talking on the phone, writing letters, doing things together, friendships will die 40 .
