My grandparents(move) to the countryside six years ago. They(live) there for six years. They like the life therethere is fresh air. They loved travelling when they were young. So far, they(visit) many countries, such as Japan, France, America and Thailand. In the past, my parents and I often(go) back to the countryside to visit them. But we haven't seen themlast year because my parents(busy) with their work and I have worked hard on my studies. My grandmother once( call) us. They have missed us so much.fact, we have also missed them. So we have decided to go back this Spring Festival since we received that call. I'm sure we'll havehappy new year.
Once there were two mice: They were friends. One mouse lived in the country;1mouse lived in the city. After many years the country mouse saw the city mouse. He said, "Come and see me at my house in the2." So the city mouse went. The city mouse said, "This food is not good,3your house is not good. Why do you live in a hole in the field? You4come and live in the city. You would live in a nice house5stone. You would have nice food to eat. You must come and see me at my house in the city."
The country mouse went to the house of the city mouse. It was a very6house. Nice food was set ready7them to eat. But just as they began to eat, they heard a great noise. The city mouse cried, "Run! Run! The cat is coming!" They ran away quickly and8. After some time they came out. The country mouse said, "I do not like living in the city. I like living in my hole in the field. For it is9to be poor and happy10to be rich and afraid."
Getting electricity has always been a problem for the 173 people living in Nuevo Saposoa, a small village in Peru, South America. However, things went from bad to worse in March 2015 after heavy rains damaged the only power cables in the area. The villagers were forced to use oil lamps, which are not only expensive but also dangerous because of the harmful gases they produce.
Luckily, researchers at the University of Technology (UT) in Lima, Peru heard about their problem and found a wonderful solution. They made a lamp that can be powered by plants and soil, both of which can be easily found in the Amazonian rainforest where the village lies. The lamp takes energy from a plant growing in a wooden box and uses it to light up an LED light bulb.
While that may sound amazing and even impossible, the science behind the idea is quite simple. As plants create their food (using the sun's energy, water and chemicals from the soil), they also produce waste which they return to the soil. Tiny animals in the soil eat this waste and they produce electrons—the building blocks of electrical energy. The UT team put special sticks inside the soil to capture the energy and keep it in the lamp's batteries for later use. The researchers say a single charge can power a 50-watt LED light for two hours —enough time for local villagers to get their evening work done.
The university gave ten Plant Lamps to the villagers of Nuevo Saposoa in October 2015. So far, they have been a huge success! Elmer Ramirez, the UT professor who invented the lamp, believes the Plant Lamp could help improve the lives of many people, especially in small rainforest communities, 42% of whom have no electricity.
