Its planned system would move peo

29、ple around in steel tubes. Those passengers would be traveling at speeds of up to 1,200 kilometers per hour. The transportation system is called Hyperloop. Work- ers plan to test the system next year in a specially built community called Quay Valley. The town will be powered entirely by energy from

30、the sun.The Hyperloop transportation system is the idea of businessman Elon usk. Dirk Ahlborn is head of Hyperloop Transportation Technologies. He says his company has taken Mr Musks idea and is developing a system that will be safe, environmentally friendly and fast. Its 100 percent solar powered .

31、 were not going to get up to 760 miles per hour, but we believe we can actually break the records that are existing right now. This means that a four-hour drive from Los Angeles, California to Las Vegas, Nevada, could someday take only 30 minutes by Hyperloop.The system involves a series of capsules

32、 that float inside a long tube. These containers wouldnt need to travel along a pathway or track. The system has been designed to operate above or below ground. Inside the tube you create a low pressure environment very similar to an airplane thats at high altitudes. So now the capsule traveling ins

33、ide the tube doesnt meet with as much resistance, and therefore can travel really fast with very little energy.Dick Ahlborn and his company will use an eight-kilometer track in Quay Valley to find the best way to set up passenger traffic and repair capsules. A larger system will cost an estimated $

34、6 billion to $10 billion to build. If Mr Ahlborn and his company succeed, we may one day see these very fast Hyperloop capsules speed- ing through tubes around the world.1.What probably makes Quay Valley special?A.It is powered by solar energy.B.It is a visitor-friendly town.

37、ts big trees since the 1930s, according to a study to be published Tuesday and cli- mate change seems to be a major factor (因素).The number of trees larger than two feet across has declined by 50 percent on more than 46 , 000 square miles of California forests, the new study finds.No area was spared

41、s had suffered the greatest water shortage.The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowm

42、elt (融雪).Since the 1930s,McIntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.1.What is the second paragrap

47、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, Gordons students have been studying ways to kill bacteria in zero gravity, an

48、d they think theyre close to a solution (解决方案). e dont 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 go

Its a hard business review of your product.Gordon says the HUNCH program has an impact (影响) on college a

50、dmissions and practical life skills. These kids are so absorbed in their studies that I just sit back. I dont teach. And that annoying bacteria? Gordon says his students are emailing daily with NASA engineers about the problem , readying a workable so- lution to test in space.1.What do we know about
