| 阅读下面的短文，回答下列五道题。 “渐”的作用，就是用每步相差极微极缓的方法来隐蔽时间的过去与事物的变迁的痕迹，使人误认其为恒久不变。这真是造物主骗人的一大诡计!这有一个比喻的故事：某农夫每天朝晨抱了犊而跳过一沟，到田里去工作，夕暮又抱了它跳过沟回家。每日如此，未尝间断。过了一年．犊已渐大，渐重，差不多变成大牛，但农夫全不觉得，仍是抱了它跳沟。有一天他因事停止工作，次日就再不能抱了这牛而跳沟了。造物的骗人，使人流连于其每日每时的欢喜而不觉其变迁与辛苦，就是用这个方法的。人们每日在抱了日重一日的牛而跳沟，不准停止。自己误以为是不变的，其实每日在增加其劳苦! 我觉得时辰钟是人生的最好的象征了。时辰钟的针，平常一看总觉得是“不动”的；其实人造物中最常动的无过于时辰钟的针了。日常生活中的人生也如此，刻刻觉得我是我，似乎这“我”永远不变，实则与时辰钟的针一样的无常!一息尚存，总觉得我仍是我，我没有变，还是留连着我的生，可怜受尽“渐”的欺骗! “渐”的本质是“时间”。时间我觉得比空间更为不可思议，犹之时间艺术的音乐比空间艺术的绘画更为神秘。______ 空间姑且不追究它如何广大或无限，我们总可以把握其一端，认定其一点。时间则全然无从把握，不可挽留，只有过去与未来在渺茫之中不绝地相追逐而已。性质上既已渺茫不可思议，分量上在人生也似乎太多。因为一般人对于时间的悟性，似乎只够支配搭船乘车的短时间；对于百年的长期间的寿命，他们不能胜任，往往迷于局部而不能顾及全体。试看乘火车的旅客中，常有明达的人，有的宁牺牲暂时的安乐而让其座位于老弱者，以求心的太平(或博暂时的美誉)；有的见众人争先下车，而退在后面或高呼“勿要轧，总有的下去的!”“大家都要下去的!”然而在乘“社会”或“世界”的大火车的“人生”的长期的旅客中，就少有这样的明达之人。所以我觉得百年的寿命，定得太长。像现在的世界上的人，倘定他们搭船乘车的期间的寿命，也许在人类社会上可减少许多凶险残惨的争斗，而与火车中一样的谦让，和平，也未可知。 A. 不管它如何广大或无限，我们总可以把握其一端，认定其一点。 B. 全然无从把握，不可挽留，只有过去与未来在渺茫之中不绝地相追逐而已。 C. 性质上渺茫不可思议。 D. 分量上在人生也似乎太多。 [单项选择]男性，74岁，右侧腹股沟区可复性肿块8年。查体：病人直立时，在腹股沟内侧端、耻骨结节上外方有一4cm×4cm半球形肿物，未进入阴囊，平卧后自行消失。该病人最有效的治疗方法是（）

Renewable Energy Sources Today petroleum（石油）provides around 40% of the world's energy needs , mostly fuelling automobiles.Coal is still used,mostly in power stations,to cover one一quarter of our energy needs,but it is the least efficient,unhealthiest and most environmentally damaging fossil fuel（矿物燃料）.Natural gas reserves could fill some of the gap from oil, but reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years.Less-polluting renewable energy sources offer a more practical long-term energy solution. "Renewable"refers to the fact t hat these resources are not used faster than they can be replaced. Hydroelectric（水力发电的）power is now the most common form of renewable energy, supplying around 20%of world electricity.China's Three Gorges Dam is the largest ever. At five times the size of the US's Hoover Dam , its 26 turbines（涡轮机）will generate the equivalent energy of 18 coal-fired power stations.It will satisfy 3% of China's entire electricity demand. In 2003, the first commercial power station to use tidal（潮汐的）currents in the open sea opened in Norway. It is designed like windmill（风车）,but others take the form of turbines. As prices fall,wind power has become the fastest growing type of electricity generation一 quadrupling（翻两番）worldwide between 1999 and 2005. Modern wind farms consist of turbines that generate electricity.Though it will be more expensive,there is more than enough wind to provide the world's entire energy needs.Wind farms come in onshore and offshore forms.They can often end up at spots of natural beauty,and are often unpopular with residents.And turbines are not totally harmless一they can intertere with radar,alter climate and kill sea birds.Scotland is building Europe's largest wind farm,which will power 200,000 homes.The UK's goal is to generate one-fifth of power from renewable sources, mainly wind,by 2020.But this may cause problems,because wind is unreliable. Which country took the lead in making use of tidal currents to produce power in 2003? A.TheUK. B.China. C.Norway. D.TheUS. 我来回答: 提交
