    You may know about the Great Barrier Reef,running some 1800 miles from New Guinea to Australia. Visitors are often takento see the reef. On one tour, one visitor asked an interesting question. "I notice that the lagoon side ofthe reef looks pale and lifeless, while the ocean side is lively and colorful.Why is this?"
    The guide answered: "The coral aroundthe lagoon side is in still water. It dies early with no challenge to itssurvival. The coral on the ocean side is always being worn by wind, waves and storms.It has to fight for its survival every day. As it is challenged, it changes andgrows healthy, and it grows strong." He added, "That′s the way it iswith every living thing."
    It is the same with people. Challenged andtoughened, we come alive! Like coral by the sea, we grow. Physical problemsmake for a stronger body. Stress makes for a stronger mind. So, if you have problems,it′s no problem! Just tell yourself, "There I grow again!"

    问答题
    Practice 5　　Maglev is a system in which the vehicle runs levitated from the guide way (corresponding to the rail tracks of conventional railways) by using electromagnetic forces between superconducting magnets on board the vehicle and coils on the ground.　　Different from conventional wheel-on-rail system, the Trans rapid accomplishes the functions of support, guidance, acceleration and braking by using non-contact electromagnetic instead of mechanical force. Because there is almost no mechanical contact Trans rapid can run with lower noise, but relatively higher speed up to 500 km/h.　　The magnetic levitation system is based on the power of attraction between the electromagnets in the vehicle and the ferromagnetic stator packs in the guide way. In contrast to the conventional trains, the propulsion system for the Trans rapid is not mounted in the vehicle but in the guide way. The long-stator linear motor in the guide way is divided into segments which are individually switched on and off, with power only being supplied to the given segment as the train passes.　　Electronically controlled support magnets located on both sides along the entire length of the vehicle pull the vehicle up to the ferromagnetic stator packs mounted to the underside of the guideway.　　Guidance magnets located on both sides along the entire length of the vehicle keep the vehicle laterally on the track. Electronic systems guarantee that the clearance remains constant (nominally10 mm). To hover, the maglev requires less power than its air conditioning equipment. The levitation system is supplied from on-b0ard batteries and thus independent of the propulsion system. The vehicle is capable of hovering up to 30 minutes without external energy. While travelling, the on-board batteries are recharged by linear generators integrated into the support magnets.　　The maglev hovers over a single or double track guide way. It can be mounted either at-grade or elevated on slim columns and consists of individual steel or concrete beams up to 62 meters in length.　　To change tracks, bendable switches are used which consist of a continuous steel beam which is elastically bent by means of electro-mechanical setting drives. Low speed switches, approx.78 meters long, are used to change tracks near stations and can be passed over in the turnout direction at 100 km/h (in the straight direction at full operating speed). High speed switches, approx.150 meters long, are used where higher turnout speeds are required (200 km/h turnout speed and in the straight direction at full operating speed).　　The maglev is propelled by a non-contact, long-stator linear motor which is installed in the guide way and functions like a rotating electric motor with the stator cut open and stretched out below the guide way.

    正确答案： 参考译文
    磁浮列车是一个系统。在该系统中,车辆利用车载超导磁铁和地面线圈之间产生的电磁吸力或斥力从导轨(相当于传统铁路的轨道)上浮升起来。
    与传统的轮轨铁路不同,磁浮列车主要是依靠无接触的电磁力、而非机械力来实现支承、导向、加速和制动功能。由于列车运行中几乎没有机械接触,因而运行起来噪声较小,时速却可高达500公里。
    磁悬浮系统依靠列车上的电磁铁和导轨中的铁磁定子之间的吸力工作。跟传统列车不同,磁浮列车的驱动系统不安装在车辆上,而是在导向轨中。导轨上的长定子线性电机被分成区段,各区段均有独立开关,只有列车通过该区段时才有电力供应。
    电子控制的悬浮磁铁贯穿车辆的两侧,这些磁铁使车辆被吸往安装在导轨下方的磁铁定子元件。
    贯穿车辆两侧的导轨磁铁使车辆水平悬浮在轨道上。电子系统可确保空隙恒定(即10毫米)。列车浮升所需功量低于车辆空调设施所需。悬浮系统由车载电池馈电。因而与驱动系统无关。在没有外部能量输入的情况下,车辆也能悬浮达30分钟之久。而在运行过程中,车载电池可由配备于悬浮磁铁中的线性发电机充电。
    磁浮列车可采用单轨或双轨运行。导轨既可水平铺设于地面,也可用细柱加以升高。导轨由钢或混凝土梁组成,每节导轨可长达62米。
    若要改道,可采用曲性道岔。这些曲性道岔由无缝钢条组成,通过机电制导装置,使其柔性弯曲。低速道岔(长约78米),用于列车临进站时改道。列车可沿道岔方向以100公里每小时的速度驶过(在直线方向不减速运行)。高速道岔(长约150米),用在那些需要列车快速通过道岔区段的地方(道岔处时速为200公里,直线方向则不减速运行)。
    磁浮列车由非接触式长定子线性电机驱动,线性电机装在导轨内,作用类似于一个定子切开后展开装在导轨下方的旋转电机。
