1、1 兰州一中2015-2016-I 学期高三年级期中考试试题 英 语 说明：本试卷分第I卷（选择题）和第 II卷（非选择题）两部分，满分120分。 考试时间100分钟。答案写在答题卡上，交卷时只交答题卡。 第一部分 阅读理解（共两节，满分40分） 第一节 (共15小题；每小题2分，满分30分)阅读下列短文，从每题所给的四个选项(A、B、C和D)中, 选出最佳选项。AAccording to the US government, wind farms off the Pacific coast could produce 900 gigawatts of electricity every ye
2、ar. Unfortunately, the water there is far too deep for even the tallest windmills to touch bottom. An experiment under way off the coast of Norway, however, could help put them anywhere. The project, called Hywind, is the worlds first large-scale deepwater wind turbine (涡轮发电机). Although it uses a fa
3、irly standard 152-ton, 2. 3-megawatt turbine, Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar, a technology Hywinds creator, the Norwegian company StatoilHydro, has developed recently. The steel spar, which is filled with stones and goe
4、s 328 feet below the sea surface, will be tied to the ocean floor by three cables ; these will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywinds stability in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind p
5、ower. If all goes according to the plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September. To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but its difficult enough to b
6、alance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spars center of gravity must be moved much closer to the oceans 2 surface. To do that, the company plans to design a new kind of wind turbine, one whose gearbox (变速箱) sits at se
7、a level rather than behind the blades. Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisibl
8、e from land, which helps overcome the windmill-as-eyesore objection. If the technology catches on, it will open up vast areas of the planets surface to one of the best low-carbon power sources available. 1. The Hywind project uses totally new technology to ensure the stability of . A. the cables whi

To balance a bigger turbine high on a floating spar, a new type of turbine is to be designedwith its gearbox si
10、tting . A. on the sea floor B. on the spar top C. at sea level D. behind the blades 3. Wide applications of deepwater wind power technology can . A. solve the technical problems of deepwater windmillsB. make financial profits by producing more turbinesC. settle the arguments about environmental prob
11、lemsD. explore low-carbon power resources available at seaB Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their fathers wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become
12、 a scientist like his father.3“Dad will be really mad if he finds out youve been playing with his new computer.”Jason said， “He told us not to touch it.”“He wont find out， ” Mark said， “Ill just have a quick look and shut it down.”Mark had been scolded before for touching his fathers equipment. But
13、his curiosity was difficult to control and this new computer really puzzled him.It was a strangelooking machineone his dad had brought home from the laboratory where he worked.“Its an experimental model， ” his father had explained， “so dont touch it under any circumstances.” But his fathers warning
14、only served to make Mark more curious. Without any further thought，Mark turned on the power switch. The computer burst into life and seconds later，the screen turned into colors，shifting and changing and then two big white words appeared in the center of the screen：“SPACE TRANSPORTER.”“Yes！” Mark cri
15、ed excitedly， “Its a computer game. I knew it！Dads only been pretending to work. Hes really been playing games instead.” A new message appeared on the screen：“ENTER NAMESVOYAGER 1：.VOYAGER 2：.”Marks fingers flew across the keyboard as he typed in both of their names.“INPUT ACCEPTED.START TRANSPORT P
16、ROGRAM. AUTORETRIEVE INITIATED(自动回收程序已启动) ”The screen turned even brighter and a noise suddenly rose in volume.“I think wed better shut it off，Mark， ” Jason yelled，reaching for the power switch. He was really frightened.But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen，wrapping the boys in its glow(光芒)，until they themselves seemed to
