题目列表(包括答案和解析)
A few degrees can make a big difference when it comes to food storage. Foods can go bad if they get too warm. But for many of the world’s poor, finding a good way to keep food cool is difficult. Refrigerators are costly and they need electricity.
Yet spoiled food not only creates health risks but also economic losses. Farmers lose money when they have to throw away products that they cannot sell quickly.
But in nineteen ninety-five a teacher in northern Nigeria named Mohammed Bah Abba found a solution. He developed the “Pot-in-Pot Preservation/Cooling System.” It uses two round containers made of clay. A smaller pot is placed inside a larger one. The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables or drinks. A wet cloth covers the whole cooling system.
Food stored in the smaller pot is kept from spoiling through a simple evaporation(蒸发) process. Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving.
The evaporation process creates a drop in temperature of several degrees. This cools the inner pot and helps keep food safe from harmful bacteria. Some foods can be kept fresh this way for several weeks.
People throughout Nigeria began using the invention. And it became popular with farmers in other African countries. Mohammed Bah Abba personally financed the first five thousand pot-in-pot systems for his own community and five villages nearby.
In two thousand, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise. This award recognizes people trying to develop projects aimed at improving human knowledge and well-being. A committee considers projects in science and medicine, technology, exploration and discovery, the environment and cultural history. Winners receive financial assistance to help develop and extend their projects.

Recently, I experienced a wonderful lesson that little things still mean a lot. I live on the Big Island of Hawaii. About a month ago, when I started my car and I 1 down at the roadside, a piece of paper caught my eye. I picked it up and 2 it carefully.
The form turned out to be a 3 from the State Motor Vehicle Division, documenting the owners’ 4 of their vehicle’s registration fees. Quickly, I put myself in their 5 and figured：no one would throw this out, 6 if it was current.
Although the form had been blown here, where in the busy, 7 parking lot would I find the owner? So I checked the date and noted the name of the 8 , who must be in our town. I thought that the best and easiest step to 9 was to put the form in an envelope addressed to the couple and 10 it by post. So I did it.
On the weekend, a 11 couple called at my house and brought me a big 12 . They said they had panicked and searched for the receipt(收据) 13 everywhere before giving up. Without it they would 14 $8, 000. It felt great to know I’d helped someone 15 a major trouble by doing something which at first glance seemed minor.
