【题目】 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(电力电缆) 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 TechnologyUTin 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 ides 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 small rainforest communities, 42% of whom have no electricity.

【题目】 New rules and behavior standards (行为规范) for middle school students came out. Who are the most excellent students? Middle schools use a new way to decide that. The best students won't only have good grades. They will also be the kids who don't dye () their hair, smoke or drink. The following are some of the new rules.

Tell the truth. Have you ever copied others' work during an exam? Don't do it again. That's not what an honest student should do. If you played computer games for two hours in your room, don't tell your parents you were doing your homework.

Do more at school. Good students love animals and care about others. April is Bird-Loving Month in China. Is your school doing anything to celebrate it? You should join! That way, you can learn more about animals and learn how to protect them. And when your classmates are in trouble, remember to give them a hand. A friend in need is a friend indeed.

Use the Internet carefully. Try to keep away from web pages that are bad for you. Find good websites and use them for homework.

Be open to new ideas. Have you ever thought that people could live on the moon? Maybe you can discover a new planet someday. Don't look down on new ideas. You should welcome them because new ideas can make life better.

【题目】 Most bees are brown, hairy and 8 to 22 mm long. Bees live as part of a large family. Over 25,000 kinds of bees have been found. Among all of them, honey bees are the most common.

Honey bees always live in groups called hives(蜂群) Each hive has a queen, drones(雄蜂)and workers(工蜂). Like a human society, each bee in a hive knows its own job.

The queen is the largest bee. She doesn’t go out to work, but lays eggs. Sometimes a queen can lay 3, 000 eggs in a day.

Drones do not collect food from flowers. They are the queen’s husbands. When there’s not much food, drones are often kicked out of the hive.

Workers are the smallest and busiest bees. A colony can have 50,000 to 60,000 workers. They collect food for the queen and babies. They guard the hive and help to keep it cool by fanning their wings. A worker only lives for 28 to 35 days.

To collect a pound of honey, a bee may have to fly a long way. Sometimes it is equivalent to(相当于) twice around the world. Bees have to visit more than 10,000 flowers to make a pound of honey.

1______________ kinds of bees have been found.

A.Over 25, 000B.Over 3,000C.Less than 25,000D.Less than 3,000
