1、BFT(阅读)-试卷 6及答案解析(总分:90.00,做题时间:90 分钟)一、Part 1(总题数:1,分数:16.00)Read the following passages, eight sentences have been removed from the article. Choose from the sentences A-H the one which fits each gap. For each gap(1-8)mark one letter(AH)on the Answer Sheet. Buzz Aldrin, the second man to walk on th
2、e Moon, is a long-time fan of space tourism. Aldrin climbed out of Apollo 11 hot on the heels of Neil Armstrong in 1969. 1 Together with scientists from Purdue University, the Massachusetts Institute of Technology, and the University of Texas, Aldrin is designing spacecrafts that would perpetually c
3、ruise between Earth and Mars. 2“Some day, people will go to Mars on a regular basis,“ says team member James Longuski, a professor at Purdue. “ 3“ The average distance between Mars and Earth is 48 million miles. 4 It sounds like a trip that would require a lot of fuel. According to the engineers, th
4、e cyclers may have a natural, renewable “fuel“ supply: from the gravitational forces of the Sun, the planets, and their moons. As a spacecraft travels close to a planet, its flight path is bent, causing it to whip around the planet and significantly increasing its speed(its as if the planets gravity
5、 gives the passing spacecraft a kick into space). 5Its not just science fiction: it might help us get Mars with very little fuel on board, in a journey that would take as little as six to eight months. “The cycler is essentially in orbit around the Sun and makes regular flybys of Earth and Mars,“ sa
6、ys James Longuski. “Once you put your vehicle into a cycler orbit, it continues on its own momentum, going back and forth between Earth and Mars. 6“ When the cycler flies by Earth, it will be traveling at a speed of about 13,000 miles per hour. 7“This is sort of like a bus that doesnt stop,“ Longusk
7、i says. “When it comes by, you have to run alongside of it and grab on.“ Aldrin and his group think that the first cycler could be on its way by as soon as 2018. 8 (It seems a long way off now, but its closer than you think!) Fasten your seatbelts and make sure your seatback is in its upright positi
8、on. Your flight to space may be departing soon.A. These crafts, known as “cyclers“, would ferry people and supplies between the two planets, enabling humans to colonize Mars something that has long been dreamed about in science fiction.B. Most people are convinced that we are going to do this; the o
9、nly question is when.C. So, if youre in middle school now, you could be taking a trip to Mars by the time youre in your thirties.D. To get a sense of just how far this is, try doing this calculation: Given that there are 2,500 miles between New York and Los Angeles, how many times would you have to
10、travel from NY to LA and back to cover the same distance?E. Now, at the age of 72, Aldrin is working on a new project that could put more of his fellow humans in space namely, on journeys to one of our most fascinating neighbors, Mars.F. This is the “slingshot“ trajectory that you may have seen in m
11、ovies.G Space taxis will be needed to bring people from the surface of the planet to intercept the cycler. H. You may need to carry some propellant for an occasional boost, but its pretty much a free trip after that.(分数:16.00)填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_二、Part 2(总题数:2,分数:
12、20.00)Read the following magazine article and answer questions 9-18 on the next page. The Burden of Thirst0. AylitoBinayos feet know the mountain. Even at four in the morning, she can rundown the rocks to the river by starlight alone and climb the steep mountain back up to her village with a contain
13、er of water on her back. She has made this journey three times a day since she was a small child. So has every other woman in her village of Foro, in the Konso district of south-western Ethiopia in Africa.1. In developed parts of the world, people turn on a tap and out pours abundant, clean water. Y
14、et nearly 900 million people in the world have no access to clean water. Furthermore, 2.5 billion people have no safe way to get rid of human waste. Polluted water and lack of proper hygiene cause disease and kill 3.3 million people around the world annually, most of them children.2. Bringing clean
15、water close to villagers homes is the key to the problem. Communities where clean water becomes accessible and plentiful are transformed. All the hours previously spent hauling water can be used to cultivate more crops, raise more animals or even start a business. Families spend less time sick or ca
16、ring for family members who are unwell. Most important, not having to collect water means girls can go to school and get jobs. The need to fetch water for the family, or to take care of younger siblings while their mother goes, usually prevents them ever having this experience.3. But the challenges
17、of bringing water to remote villages like those in Konso are overwhelming. Locating water underground and then reaching it by means of deep wells requires geological expertise and expensive, heavy machines. Abandoned wells and water projects litter the villages of Konso. In similar villages around t
18、he developing world, the biggest problem with water schemes is that about half of them break down soon after the groups that built them move on. Sometimes technology is used that cant be repaired locally, or spare parts are available only in the capital.4. Today, a UK-based international non-profit
19、organisation called Water Aid is tackling the job of bringing water to the most remote villages of Konso. Their approach combines technologies proven to last - such as building a sand dam to capture and filter rainwater that would otherwise drain away. But the real innovation is that Water Aid belie
20、ves technology is only part of the solution. Just as important is involving the local community in designing, building and maintaining new water projects.5. The people of Konso, who grow their crops on terraces they have dug into the sides of mountains, are famous for hard work. In the village of Or
21、besho, residents even constructed a road themselves so that drilling machinery could come in. Last summer, their pump, installed by the river, was being motorised to push its water to a newly built reservoir on top of a nearby mountain. From there, gravity will carry it down in pipes to villages on
22、the other side of the mountain. Residents of those villages have each given some money to help fund the project. They have made concrete and collected stones for the structures. Now they are digging trenches to lay pipes. If all goes well, AylitoBinayo will have a tap with safe water just a three-mi
