Article: The first day my new teacher walked into our school in Spanish Harlem, I burst out laughing. Ron Clark was a young white guy from North Carolina who talked with a funny Southern accent . He said he used to be a singing waiter. I thought, who is this guy? He's a complete joke. It was 1999 and I was in the fifth grade at New York City's P.S. 83. _ . I'd always been a troublemaker. I'd get yelled at, and then the teachers would give up on me. I thought that's what would happen with Ron Clark. I was wrong. That first week, I kept mocking him. He pulled me out to the hallway and said I'd better shape up. "Tamara," he said, "you're a smart kid. You can do better." He told me I was a natural leader and that I'd go far in life if I started applying myself. I was mad at first, but then something happened: I began to respect him. There were 29 students in our class, and it didn't take long for us to realize that Ron Clark was no ordinary teacher. He was only 27 and had the most unusual way of teaching. To help us learn the states and capitals, he changed the lyrics of a popular rap hit called "Thong Song" and had us sing and dance with him. When we read the Harry Potter books, he decorated our classroom like Hogwarts. And during the Presidential election, he put campaign posters on the walls and covered the room with 5,000 red, white and blue stars.
Answer: Disdainful .
What's the author's attitude toward the new teacher on the first day?

Article: Meet Jeff Wilson AKA Professor Dumpster , an environmental scientist and the Dean of Huston Tillotson University in Austin, Texas. The reason for his unusual nickname? He has decided to live in a dumpster for the next year. Yes, the kind that you might find filled with trash behind a restaurant. Wilson says the inspiration to do something first hit him two years ago, when he was working on an article at a neighborhood coffee shop and caught sight of an eight-yard dumpster. Now that he has found one, Professor Dumpster is putting his students to work. After all, the point of this project isn't just to spend his life living out of a garbage can: there is, a much greater purpose involved. As an environmental scientist, the professor constantly thinks about sustainable living and how every person should try to minimize his/her impact on our already stretched resources. That, is the challenge Wilson wanted his students to step up to, this entire year. Using their math, science, engineering and technology skills, he wants them to retrofit his 33 square-foot dumpster into a modern space that includes a shower, a toilet, a kitchen and a bed and is fitted with conveniences like air-conditioning and even WiFi. The demand? It all has to be green and sustainable. www.ks5u.com So why is Wilson planning to go through such hardship? That is because he wants to equip his students with the tools to survive in a world that is rapidly heading towards a population of 10 billion people. A large majority of the population adjust to living in tighter spaces in the world where resources and space should be limited to be used. By promoting awareness and education on these subjects, Wilson is helping students everywhere see that living "small" and sustainably is certainly possible. And while the dumpster project may seem a little crazy to some, the professor thinks of it as a "playful and imaginative" educational experiment and conversation-starter to discuss the fact that all of us can do with less as we move into the future.
Answer: Finding sustainable living ways of using fewer resources.
What is Jeff Wilson concerned about all the time?

Article: How can you find out what is going on inside a person's body without opening the patient's body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs. What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient's body. Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed. A CAT scanner, however, uses a group of X rays to give a cross-sectional view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear "photos" of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can "stop the action", giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient. Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don't cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays. CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.
Answer: It gives clear pictures of active, moving body parts.
