| 第1题： {{B}}Reading SectionDirections{{/B}} In this section you will read five passages and answer reading comprehension questions about each passage. Most questions are worth one point, but the last question in each set is worth more than one point. The directions indicate how many points you may receive. You will have 60 minutes to read all of the passages and answer the questions. Some passages include a word or phrase that is underlined in blue.Click on the word or phrase to see a definition or an explanation. When you want to move on to the next question, click on {{B}}Next{{/B}}. You can skip questions and go back to them later as long as there is time remaining. If you want to return to previous questions, click on {{B}}Back{{/B}}. You can click on {{B}}Review{{/B}} at any time and the review screen will show you which question you have answered and which you have not. From this review screen, you may go directly to any question you have already seen in the reading section. When you are ready to continue, click on the {{B}}Continue{{/B}} icon. {{B}}Set 1{{/B}} It looks as if it came straight from the set of Star Wars. It has four-wheel drive and rises above rocky surfaces. It lowers and raises its nose when going up and down hills.And when it comes to a river, it turns amphibious: two hydrojets power it along by blasting water under its body. There is room for two passengers and a driver, who sit inside a glass bubble operating electronic, aircraft-type controls.A、vehicle so daring on land and water needs windscreen wipers — but it doesn’t have any. Water molecules are disintegrated on the screen’s surface by ultrasonic sensors. This unusual vehicle is the Racoon. It is an invention not of Hollywood but of Renault, a rather conservative French state-owned carmaker, better known for its family hatchbacks. Renault built the Racoon to explore new freedoms for designers and engineers created by advances in materials and manufacturing processes. Renault is thinking about startlingly different cars; other producers have radical new ideas for trains, boats and aeroplanes. The first of the new freedoms is in design. Powerful computer-aided designCAD、systems can replace with a click of a computer mouse hours of laborious work done on thousands of drawing boards. So new products, no matter how complicated, can be developed much faster. For the first time,Boeing will not have to build a giant replica of its new airliner, the 777, to make sure all the bits fit together. ItsCAD、system will take care of that. But Renault is takingCAD、further. It claims the Racoon is the world’s first vehicle to be designed within the digitised world of virtual reality.Complex programs were used to simulate the vehicle and the terrain that it was expected to cross. This allowed a team led by Patrick Le Quement, Renault’s industrial-design director, to "drive" it long before a prototype existeD、 Renault is not alone in thinking that virtual reality will transform automotive design. InDetroit, Ford is also investigating its potential. Jack Telnac, the firm’s head of design, would like designers in different parts of the world to work more closely together, linked by computers. They would do more than style cars. Virtual reality will allow engineers to peer inside the working part of a vehicle.Designers will watch bearings move, oil flow, gears mesh and hydraulics pump.As these techniques catch on, even stranger vehicles are likely to come along. Transforming these creations from virtual reality to actual reality will also become easier, especially with advances in materials. Firms that once bashed everything out of steel now find that new alloys 【分析题】： | |

| 第3题：Scientists have discovered that for the last 160,000 years, at least, there has been a consistent relationship between the amount of carbon dioxide in the air and the average temperature of the planet. The importance of carbon dioxide in regulating theEarth’’s temperature was confirmed by scientists working in eastern(5)Antarctic A、Drilling down into a glacier, they extracted a mile-long cylinder of ice from the hole. The glacier had formed as layer upon layer of snow accumulated year after year. Thus drilling into the ice was tantamount to drilling back through time. The deepest sections of the core are composed of water that fell as snow 160,000 years ago. Scientists in Grenoble, France, fractured portions of the core andtemperature and of atmospheric(10)measured the composition of ancient air released from bubbles in the ice. Instruments were used to measure the ratio of certain isotopes in the frozen water to get an idea of the prevailing atmospheric temperature at the time when that particular bit of water became locked in the glacier. The result is a remarkable unbroken record of (15)levels of carbon dioxide.Almost every time the chill of an ice age descended on the planet, carbon dioxide levels droppeD、When the global temperature dropped 9F (5℃), carbon dioxide levels dropped to 190 parts per million or so. Generally, as each ice age ended and theEarth basked in a warm interglacial period, carbon dioxide levels were around 280 parts per million. Through the 160,000 years of that ice(20)record, the level of carbon dioxide in the atmosphere fluctuated between 190 and 280 parts per million, but never rose much higher-until the industrial Revolution beginning in the eighteenth century and continuing today. There is indirect evidence that the link between carbon dioxide levels and global temperature change goes back much further than the glacial recorD、Carbon(25)dioxide levels may have been much greater than the current concentration during theCarboniferous perioD、360 to 285 million years ago. The period was named for aprofusion of plant life whose buried remains produced a large fraction of the coal deposits that am being brought to the surface and burned today.Which of the following does the passage mainly discuss A、Chemical causes of ice ages B．Techniques for studying ancient layers of ice in glaciers C．Evidence of a relationship between levels of carbon dioxide and global temperature D．Effects of plant life on carbon dioxide levels in the atmosphere |
