A camp built by students and volunteers spreads over Southern Methodist University（SMU）. The affordable 21 are designed to be used by the poor as well as survivors of war and natural disasters. “By the time 2020, there’s going to be about 1.7 billion people living in slums（贫民窟） so we would like to 22 change,” says Stephanie Hunt, co-founder of the Hunt Institute for Engineering and Humanities at SMU. The institute, which 23 build the village on SMU’s campus, was established to solve problem of the poor in the United States and around the world through engineering, and the free 24 . The goal is not just to 25 lives, but to change the victims’ lives. The Institute hopes some entrepreneurs（企业家） might program and 26 some money with these ideas. One of the structures in the SMU village was built with bricks made 27 from recycled plastic bags. They’re 28 together with heavy wires. Harvey Lacey, father of two college-aged sons, including one here at SUM, heard about this project and 29 his invention. It’s a heavy-duty, hand-crank compactor（手动压缩机）that anybody can use to form the big bricks he calls Ubuntu Blox. “The advantages are that these 30 weigh less than two pounds. They’re very, very 31 These things can go for many generations of housing, ”says Lacey, who is 32 the design. Anybody can follow his online plans to 33 the compactor that turns plastic bags into bricks. On this warm day, it’s 34 inside the Ubuntu Blox hut, thanks 35 to the thick plastic insulation（绝缘）. Kenyan 36 Ronald Omyonga, visiting the global village before returning to his native Africa, says his country is full of these recyclable bags. With Lacey’s design, he says that litter could be transformed into 37 housing. He dreams of other 38 too. “Look at the Harvey Lacey hut, as a means of creating 39 ,”says Omyonga.“Leaning the environment, and turning 40 into something that can form houses, not just for the poor.” 小题1: A．shelters B．clubs C．parties D．rooms 小题2: A．affect B．adapt C．effect D．adopt 小题3: A．discovered B．helped C．studied D．explored 小题4: A．entry B．competition C．trade D．market 小题5: A．save B．survive C．defend D．cure 小题6: A．share B．donate C．earn D．cost 小题7: A．briefly B．relevantly C．mostly D．efficiently 小题8: A．held B．stressed C．knocked D．packed 小题9: A．delivered B．contributed C．devoted D．sacrificed 小题10: A．piles B．masses C．loaves D．blocks 小题11: A．fragile B．thick C．hard D．bitter 小题12: A．giving out B．giving off C．giving up D．giving away 小题13: A．build B．invent C．improve D．possess 小题14: A．hot B．cold C．wet D．cool 小题15: A．nearly B．exactly C．partly D．fairly 小题16: A．doctor B．athlete C．photographer D．architect 小题17: A．safe B．dangerous C．beautiful D．large 小题18: A．advantages B．chances C．benefits D．profits 小题19: A．things B．jobs C．wonders D．conditions 小题20: A．waste B．resources C．ideas D．technology
