面的

面的是微型面包的士车的简称,在上世纪80年代末90年代初,应着“以低档车辆、廉价车费满足市民需求”的口号出现的最早期的出租车。曾经仅北京一地就拥有面的十万辆以上,在给市民提供着巨大的便利的同时,也给城市制造着严重的尾气污染。面的的土黄色的消隐,湛蓝的天空开始有了归期。作为北京市治理大气污染紧急措施中的一项,1998年12月23日,北京数千辆“面的”在首钢被请进了化铁炉。

工作

工作,是一个汉语词语,具有动词、名词两种词性。作为动词用有操作、行动、运转、运作等意思。作为名词用有工程、制作、业务、任务、职业、从事各种手艺的人等意思。工作的概念是劳动生产,主要是指劳动。一个人的工作是他在社会中所扮演的角色。在社会主义国家,工作是社会分工中每个劳动者体现社会价值和自我价值的角色定位。所谓工作就是劳动者通过劳动(包括体力劳动和脑力劳动)将生产资料转换为生活资料以满足人们生存和继续社会发展事业的过程。一个人从事什么工作,由其所处社会环境和个人能力(包括认知)共同决定,因此不能用有色眼镜去看一个人所从事的工作。

衣服上的静电会在指尖迸出噼叭的火花,月球上静电的威力可就远远不止如此。据研究发现,月球表面静电场的电压可高达4500伏,足以令监视器、太空车、月球基地门上的电子仪器发生故障,飘浮在空中的带电月球微尘亦会堵塞各种装置设备。研究人员指出,经过地球磁尾和被太阳风暴袭击是月球表面形成静电场的主要原因,前者可以预测,后者却防不胜防。如果在太阳风暴袭来,宇航员最需要提前获得警报,从而安全返回基地躲避之时,各种设备却因静电而失去作用,对于月球上的移民来说,无疑是雪上加霜。对这段话理解正确的一项是(  )。
