7.The elevator of the future may be just over the horizon thanks to German company ThyssenKrupp.The firm has invented a cable-free elevator (called MULTI) that can go up and down like traditional lifts but the magnetic motors allow it to go side-to-side too.The designers predict that this technology could incrase the carrying capacity of existing architecture by as much as 50%.Plus it looks really neat.ThyssenKrupp plans to use light-weight materials to build its elevator ears of the future and the lack of a cable winch(钢缆绞车)will reduce weight as well.The ears wouldn't just move up and down as they do now but would instead go in a circle that allows more cars to slip in fight behind the next.The result is that you might only have to wait 10seconds for the next one to arrive rather than wait for the one you just missed to come back down.
The technology backing ThyssenKrupp's MULTI elevator is very similar to magnetic levitation(磁悬浮)systems used in high-speed trains.Each car has two magnetic motors-one for vertical movement and another for horizontal.This system can also deliver power to the car's internal lighting and electronics without using wires.
A traditional cable driven elevator has mechanical components that can hold the car in place in the event of a power-off.ThyssenKrupp didn't go into detail about safety measures in its announcement but it's safe to say the magnetic levitation elevator will have some sort of system to hold it in place if the lights go out.ThyssenKrupp is working on a test tower that will be used to develop the MULTI into a real elevator technology.This should be up and running by 2016but it will probably take at least a few more years before you get to climb inside a magnetic elevator car.

分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了德国蒂森克虏伯公司发明为了的新电梯,会更加方便人类的生活.
解答 32.C.词义猜测题.根据第一段The elevator of the future may be just over the horizon thanks to German company ThyssenKrupp可知未来的电梯可能只是在路上由于德国蒂森克虏伯公司的发明;故选C.
33.B.推理判断题.根据第一段The designers predict that this technology could incrase the carrying capacity of existing architecture by as much as 50%.Plus it looks really neat可知multi设计能承载更多乘客;故选B.
34.A.细节理解题.根据第三段The technology backing ThyssenKrupp's MULTI elevator is very similar to magnetic levitation(磁悬浮)systems used in high-speed trains.Each car has two magnetic motors-one for vertical movement and another for horizontal可知多智能体的关键技术是磁电机;故选A.
35.D.细节理解题.根据最后一段ThyssenKrupp is working on a test tower that will be used to develop the MULTI into a real elevator technology可知multi已经有一个安全系统万一发生断电情况;故选D.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
