【正文】 till（蒸餾器）is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the . Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it’s all but impossible to find natural substitutes. The only ponents required, though, are a 5′5′ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container— perhaps just a drinking cup — to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole. Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone (圓錐體) with 45degreeangled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup. The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸發(fā)) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won’t have to break down the still every time you need a drink. 32.

UNESCO( United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(聯(lián)合) voice across cultures.Despite the celebrations, though, in the . the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.It’s Jason Moran’s job to help change that. As the Kennedy Center’s artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.“Jazz seems like it’s not really a part of the American appetite,” Moran tells National Public Radio’s reporter Neal Conan. “What I’m hoping to acplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It’s actually color, and it’s actually digital.”Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. “The music can’t be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,” says Moran.Last year, Moran worked on a project that arranged Fats Waller’s music for a dance party, “Just to kind of put it back in the mind that Waller is dance music as much as it is concert music,” says Moran. “For me, it’s the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context,” says Moran, “so I want to continue those dialogue. Those are the things I want to foster.”28. Why did UNESCO set April 30 as International Jazz Day? A. To remember the birth of jazz. B. To protect cultural diversity. C. To encourage people to study music. D. To recognize the value of jazz.29. What does the underlined word “that” in Paragraph 3 refer to? A. Jazz being more accessible. B. The production of jazz growing faster. C. Jazz being less popular with the young. D. The jazz audience being larger. 30. What can we infer about Moran’s opinion on jazz? A. It will disappear gradually. B. It remains black and white. C. It should keep up with the times. D. It changes every 50 years.31. Which of the following can be the best title for the text? A. Exploring the Future of jazz. B. The
