单选题After flexing its mechanical arm and finding some puzzling chemistry in a patch of Martian soil,the robotic rover Spirit began investigating the composition of a rock named Adirondack yesterday with two science instruments and a microscopic camera. Following programmed instructions from flight controllers, the six-wheel rover made several short turns and moved forward about six feet. It stopped within inches of the pyramid-shaped rock, about the size of a football. It was the vehicle's second maneuver on the Martian surface since landing there on Jan. 3. Scientists at the Jet Propulsion Laboratory in Pasadena, Calif., said they did not expect results of the first rock examination until early today. But they were already both pleased and puzzled over the soil test results. "We're starting to put together a picture of what the soil at Gusev is really like," Dr. Steven W. Squyres of Cornell, the principal scientist of the mission, said at a news conference in Pasadena. He was referring to the Spirit's landing site in Gusev crater, near the Martian equator. Two of the Spirit's main science instruments, the M6ssbauer spectrometer and the alpha particle X-ray spectrometer, made a close examination of soil near the landing base. German scientists in charge of the studies reported that X-rays emitted by the surface soil indicated a chemical composition mainly of silicon and iron, with smaller amounts of sulfur, chlorine and argon. Argon is a noble gas that is part of the Martian atmosphere. Previous Martian sites visited by landing craft also contained significant amounts of sulfur and chlorine. Other members of the project's science team said the M6ssbauer spectrometer found considerable amounts of the mineral olivine in the soil. Olivine, which contains oxygen, iron and magnesium, is often found in volcanic rocks. The Martian soil may resemble the volcanic soil of Hawaii. "One possibility is that this soil is simply ground-up lava," Dr. Squyres said. "That would surprise me, but it's entirely possible that beneath .those grains there is solid rock and we are detecting some of that solid rock, not the s0il." Another property of the soil perplexed geologists. The fine grains of the Gusev surface seem to stick together in dry clumps. Geologists suspected static electricity as the clinging force. If so, they said, the soil should collapse and flatten out when the M6ssbauer spectrometer pressed against the ground. Nothing collapsed, leading Dr. Squyres to ask what force was. responsible for holding them together.

单选题At the University of California at Los Angeles (UCLA) , a student loaded his class notes into a handheld e-mail device and tried to read them during an exam: a classmate turned him in. At the University of Nevada at Las Vegas (UNLV) students photographed test questions with their cell phone cameras and transmitted them to classmates. The university put in place a new examination-supervision system. "If they'd spend as much time studying, they'd all be A students," says Ron Yasbin, dean of the College of Sciences of UNLV. With a variety of electronic devices, American students find it easier to cheat. And college officials find themselves in a new game of eat and mouse. They are trying to fight would-he cheats in the exam season by cutting off Internet access from laptops(笔记本电脑), demanding the surrender of cell phones before tests or simply requiring that exams be taken with pens and paper. "It is annoying. My hand-writing is so bad," said Ryan Dapremont, 21 who just finished his third year at Pepperdine University in California. He had to take his exams on paper. Dapremont said technology has made cheating easier, but plagiarism(剽窃) in writing papers was probably the biggest problem. Students can lift other people's writings off the Internet without attributing them. Still, some students said they thought cheating these days was more a product Of the mindset, not the tools at hand. "Some people put too much emphasis on where they're going to go in the future, and all they're thinking about is graduate school and the next step," said Lindsay Nicholas, a third-year student at UCLA. She added that pressure to succeed "sometimes clouds everything and makes people do things that they shouldn't do. " Some professors said they tried to write exams for which it was hard to cheat, posing questions that outside resources would not help answer. Many officials said that they rely on campus honor codes. They said the most important thing was to teach students not to cheat in the first place.
