thousand of these volcanoes on Earth，all but a few hundred of them extinct. There is，however，a second less known type of volcano that doesn't involve mountain building. These are volcanoes so explosive that they burst open in a single big crack，leaving behind a vast hole，the caldera. Yellowstone obviously was of this second type，but Christiansen couldn't find the caldera anywhere.
Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up for one of the visitors' centers. As soon as Christiansen saw the photos，he realized why he had failed to spot the caldera; almost the whole park-2.2 million acres—was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans. 24. What puzzled Christiansen when he was studying Yellowstone？ A.Its complicated geographical features. B. Its ever-lasting influence on tourism. C. The mysterious history of the park. D. The exact location of the volcano.
25. What does the second-paragraph mainly talk about？ A. The shapes of volcanoes. B. The impacts of volcanoes. C. The activities of volcanoes. D. The heights of volcanoes.
26. What does the underlined word \blow-up\in the last paragraph most probably mean？ A. Hot-air balloon. C. Big photograph.
B. Digital camera. D. Bird's view.
C

very tiny big problem? It’s turning to a bunch of high school kids. But not just any kids. It isdepending on NASA HUNCH high school classrooms, like the one science teachers Gene Gordon and Donna Himmelberg lead at Fairport High School in Fairport, New York.
HUNCH is designed to connect high school classrooms with NASA engineers. For the past two years, Gordon’s students have been studying ways to kill bacteria in zero gravity, and they think they’re close to a solution（解决方案）. “We don’t give the students any breaks. They have to do it just like NASA engineers,” says Florence Gold, a project manager.
“There are no tests,” Gordon says. “There is no graded homework. There almost are no grades, other than‘Are you working towards your goal?’ Basically, it’s ‘I’ve got to produce this product and then, at the end of year, present it to NASA.’ Engineers come and really do an in-person review, and…it’s not a very nice thing at times. It’s a hard business review of your product.”
Gordon says the HUNCH program has an impact（影响） on college admissions and practical life skills. “These kids are so absorbed in their studies that I just sit back. I don’t teach.” And that annoying bacteria? Gordon says his students are emailing daily with NASA engineers about the problem, readying a workable solution to test in space.
27.What do we know about the bacteria in the International Space Station? A. They are hard to get rid of. C. They appear different forms.
B. They lead to air pollution. D. They damage the instruments.
28. What is the purpose of the HUNCH program? A. To strengthen teacher-student relationships. B. To sharpen students’ communication skills. C. To allow students to experience zero gravity. D. To link space technology with school education
29. What do the NASA engineers do for the students in the program? A. Check their product. C. Adjust work schedules.
B. Guide project designs D. Grade their homework.

30. What is the best title for the text? A. NASA: The Home of Astronauts. B. Space: The Final Homework Frontier. C. Nature: An Outdoor Classroom. D. HUNCH:A College Admission Reform.
