6、CcriticalDnormal二、阅读判断Europas watery underworldEuropa, one of Jupiters 63 known moons, looks bright and icy on the surface. But appearances can be deceiving: Miles within its cracked, frigid shell, Europa probably hides giant pools of liquid water. Where scientists find liquid water, they hope to fi

7、nd life as well.Since we cant go diving into Europas depths just yet, scientists instead have to investigate the moons surface for clues to what lies beneath. In a new study, scientists investigated one group of strange ice patterns on Europa and concluded that the formations mark the top of an unde

8、rground pool that holds as much water as the U.S. Great Lakes.Pictures of Europa, which is slightly smaller than Earths moon, clearly show a tangled, icy mishmash of lines and cracks known as “chaos terrains.” These chaotic places cover more than half of Europa. For more than 10 years, scientists ha

9、ve wondered what causes the formations. The new study suggests that they arise from the mixing of vast underground stores of liquid water with icy material near the surface.For scientists who suspect that Europa also may be hiding life beneath its icy surface, the news about the new lake is exciting

10、.“It would be great if these lakes harbored life,” Britney Schmidt, a planetary scientist who worked on the study, told Science News. “But even if they didnt, they say that Europa is doing something interesting and active right now.”Schmidt, a scientist at the University of Texas at Austin, and her

11、colleagues wanted to know how chaos terrains form. Since they couldnt rocket to Europa to see for themselves, they searched for similar formations here on Earth. They studied collapsed ice shelves in Antarctica and icy caps on volcanoes in Iceland. Those features on Earth formed when liquid water mi

12、xed with ice. The scientists now suspect something similar might be happening on Europa: that as water and ice of different temperatures mingle and shift, the surface fractures. This would explain the jumbled ice sculptures.“Fracturing catastrophically disrupts the ice in the same way that it causes

13、 ice shelves to collapse on Earth,” Schmidt told Science News. She and her team found that the process could be causing chaos terrains to form quickly on Europa.The new study suggests that on this moon, elements such as oxygen from the surface blend with the deep bodies of water. That mixture may cr

Technology moves faster than the education system. Teachers

27、 must teach at the pace of the slowest student rather than the fastest. And particularly in the United States school children as a group dont care much for, or excel(擅长)at, mathematics. So its heartening to learn that a new kind of “classroom of the future” shows promise at mitigating some of these

28、problems, starting with that fundamental piece of classroom furniture: the desk.AUK study involving roughly 400 students, mostly aged 8-10 years, and a new generation of multicultural, mufti-user, computerized desktop surfaces is showing that over the last three years the technology has appreciably

29、boosted students math skills compared to peers learning the same material via the conventional paper-and-pencil method. How? Through collaboration, mostly, as well as by giving teachers better tools by which to micromanage individual students who need some extra instruction while allowing the rest o

30、f the class to continue moving forward.Traditional instruction still shows respectable efficacy (效力) at increasing students fluency in mathematics, essentially through memorization and practice dull, repetitive practice. But the researchers have concluded that these new touchscreen desks boost both

31、fluency and flexibility the critical thinking skills that allow students to solve complex problems not simply through knowing formulas and devices, but by being able to figure out what the real problem is and the most effective means of stripping it down and solving it.One reason for this, the resea

32、rchers say, is the mufti-touch aspect of the technology. Students working in the next-gen classroom can work together at the same tabletop, each of them contributing and engaging with the problem as part of a group. Known as Synergy Net, the software uses computer vision systems that see in the infrare
