Elephants might be the most well-known and well-loved animal in African wildlife. But conservation of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa. Years ago, over hunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans , hunting rules and protected areas protect elephants from these dangers today. The 21st century brings a different challenge to elephant conservation --land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts between local farmers and these big animals. Successful conservation strategies must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people. AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants. The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants. To protect elephants, the AWF does all the following EXCEPT _ . A) keeping elephants B) protecting elephants' habitats C) doing research on elephants D) helping farmers improve their life

Schools across the country are turning green. So-called green schools are built from recycled and environmentally friendly materials. They are designed to use less energy than traditional school buildings. In the next few years, Southern California alone plans to open 150 green schools. Studies have shown that there are good reasons to go green, including good air quality that cuts down on asthma attacks and airborne germs that can cause illnesses. Students learn better in classrooms that have natural light and ideal temperatures. Green schools have lower energy bills. Go On, Get Green Here's how to save energy and help the environment. Light Savers Turn off the lights in a room when it is not in use. This bright idea can produce big savings on energy costs. Some schools use sensors that automatically shut off the lights when there is no motion in a room. Heat Smart Your school's thermostat should be set to 78degCin warm weather and 68degCin cooler weather. The temperature can be even farther from the comfort zone at night and on weekends, when no one is using the school building. Reuse, Recycle Reuse paper, cans, bottles and batteries. Use both sides of notebook paper. Carry a lunch box rather than a paper bag. Recycle whatever you can reuse. Don't Drip Leaky taps can waste large amounts of water. A small, steady flow can add up to hundreds of gallons a year. Report drips if you see them. In a green school, students will _ . A) use both sides of their notebook paper B) not use lights at all C) use paper bags to carry food D) get sick more easily

Q: Mark felt that it was time for him to take part in his community activities, so he went to the neighborhood meeting after work. The city councilman was leading a discussion about the decreasing life quality. The neighborhood faced many problems. Mark looked at the charts taped to the walls. There are charts for crime, parking problems, and for problems in vacant buildings. People were supposed to suggest solutions to the councilman. It was too much for Mark. "The problems are too big," he thought. He turned to the man next to him and said, "I think this is a waste of my time. Nothing I could do would make a difference here." Mark thought some more on his way to the bus stop. "People should just take care of themselves," he decided. "That's enough to do. I can't take on all the problems of the world." As he neared the bus stop, Mark saw a woman carrying a grocery bag and a baby. She was trying to unlock her car, but she didn't have a free hand. As Mark got closer, her other child, a little boy, suddenly _ into the street. The woman tried to reach for him, but as she moved, her bag shifted and groceries started to fall out. Mark ran to take the boy's arm and led him back to his mother. Then he picked up the groceries while the woman smiled in relief. "Thanks!" she said. "You have got great timing!" "Just being neighborly," Mark said. As he rode home, he glanced at the walls of the bus. On one of them was "Small acts of kindness add up." Mark smiled and thought, " Maybe that's a good place to start." This passage mainly wants to tell us _ . A) how each of us can help make a difference B) how a neighborhood meeting can solve its problems C) how citizens react to the problems they face D) how problems are solved through group action
A: C
*Question*
I can't remember a winter being as cold as this in Pennsylvania, but I'm sure there were colder days. Even though the daylight hours are growing longer minute by minute, it's easy to find an excuse not to go out unless you ly must, but then again I often have to push myself to accomplish things. People I speak to have been in all kinds of _ moods. They say they're "under the weather," not feeling good about this time of year. As I stood outside with my two dogs yesterday, it was so cold that my nose and face felt frozen and my ears were stinging. Of course, that doesn't matter to Ricky and Lucy. They have a routine they must go through to find just the fighting spot no matter how cold or hot it is. So I wait. But this time it was different. As cold as it was, I suddenly was excited thinking about how wonderful this extreme cold really was. Then the sun broke through the clouds and memories of summer's extremely hot days flashed through my mind. I could remember standing in the heat of the afternoon, with sweat pouring down my brow and the hot, burning sun against my face. I reminded myself then and there that in the cold of the winter I would wish I had this heat. I was grateful for the extremes. Without the extremes in my life, I would never appreciate the days when things were just right. Without the extremes, life would be boring. It's being pushed to one of the extremes that makes us appreciate the middle more. Health challenges remind us that we need to pay more attention to how we live. Financial extremes remind us that when things go smoothly it's also time to save for raining days. ks5u I've come to the conclusion that all too often I find a reason not to be happy with where I am at that moment. Whether it's hot or cold, good health or bad, in the money or out of it, I always want it to be different. I'm tired of being "Under the Weather!" That day the writer waited in the terrible cold because _ . A) his dogs wanted to hunt B) he wanted to face the cold bravely C) his dogs had a routine D) he wanted to be different
