【题目】阅读理解
阅读下列短文,从每题所给的四个选项 (A 、B 、C 和 D )中,选出最佳选项。
In 1841, a book was published which astonished the world. It was called “Incidents of Travel in Central America, Chiapas and Yucatan”. The author John Loud Stephens had just returned from a long, difficult and dangerous journey through the thick rain forest of southern Mexico and Guatemala. He had once been there with Frederick Catherwood, an architect and artist, to search for the remains of a lost civilization known as the Mayas(玛雅). Very little was known about the Mayas at that time, but Catherwood's drawing in the book showed incredible cities with temples, pyramids and other buildings as impressive as those of their northern neighbors, the Aztecs. These cities, however, were deserted. The inhabitants(居民) had disappeared almost a thousand years before.
Since that time, far more has been learned about this remarkable civilization. The Mayas had a highly-developed system of government and of agriculture, as well as an incredibly accurate system of measuring time. They were also wonderful engineers capable of moving huge blocks stone long distances and cutting them to accurate shapes and sizes.
And yet although the Mayas knew about the wheel, they never used it. Neither did they use metals other than copper. What is ever more surprising is that they suddenly abandoned many of their cities and built new ones in the jungle. Some time around AD 900, Mayan civilization collapsed(崩溃). By the year 1200, their last great capital,
Who were these strange people and the even stranger gods they worshipped? What brought about their sudden and mysterious collapse? Some writers have tried to prove that the Mayas had contact with visitors from space and even that they themselves came from another planet. Some people believe that their civilization came to an end because the Mayas never developed a proper resistance to local germs and diseases. All we really know is that when the first Europeans appeared off their coast in 1517, this great and mysterious culture was only a memory.

【题目】近来时见“又一波雾霾汹涌来袭”“京津冀持续受雾霾困扰”,以及“中央气象台继续发布霾黄色预警”和“部分地区有重度霾”等报道,雾霾已严重危害到了人们的身体健康。所以,新修订的《环境保护法》,已涉及关于如何治理雾霾,尤其是霾的问题。
霾和雾有所不同。“雾”是一种自然天象,古人有“薄雾浓云”“雾失楼台”之类吟咏,从诗画的角度看,雾柔美、朦胧而神秘。霾就不同了。虽说也是自古就有的一种天象,却全然无此美感,而且随着人为因素越来越频繁地介入,如今已成了一种污染。现代辞书因此释义为“空气中因悬浮着大量的烟、尘等微粒而形成的浑浊现象”。按当下民间流行的通俗说法,就是PM2.5(细颗粒物)严重超标。
霾习惯上也叫阴霾、灰霾或烟霾,这是霾给人的一种很形象的视觉感受:阴沉沉的,灰蒙蒙的,满天烟尘。近来竟与“雾”组合成“雾霾”而频频见诸报端。词典中不见“雾霾”这个词,只有“霾雾”(如《后汉书·郎传》“霾雾蔽日”)和“风霾”(如《魏书·崔光传》“昨风霾暴兴”),此外还有“尘霾”“沙霾”“黄霾”等。虽然词典中不见“雾霾”一词的身影,但它却在2013年“荣升”为年度热词。
从形式上看,热词“雾霾”是旧词“霾雾”的倒序,但词义的重心却因此起了变化。“霾雾”原是“夹杂有尘霾的雾”,中心词是“雾”;“雾霾”则是“像迷雾一样的霾”,中心词就成了“霾”。
“霾”并非新字,早在甲骨文中就已屡见,卜辞有“癸卯卜,王占曰,其霾甲辰”和“贞兹雨不霾”之类的记载,可见霾很早就对人们的生活有影响了。前人对霾的认识,从《尔雅》到《康熙字典》乃至20世纪初编成的《中华大字典》,释义几乎是一以贯之的,其中汉刘熙《释名·释天》的释义相对比较全面:“风而雨土曰霾。霾,晦也,言如物尘晦之色也。”“雨”在这里读为yù,作动词“降下”讲,意谓大风扬起的尘土从天而下就是霾。因为空中满是尘土,所以刘熙说霾的天象是“晦”,天色像物体被蒙上了尘土一样昏暗。《晋书·天文志》说:“凡天地四方昏濛若下尘,十日五日已上,或一月,或一时,雨不沾衣而有土,名曰霾。”可见,满天尘土的“霾”,与雾不同,可以持续多日,甚至长达一个月。《元史》也有至元六年(1340年)腊月“风霾蔽都城数日”的记载。
“霾”字从结构上说,是“从雨貍声”。义符是“雨”,说明是一种天象无疑。只是为何要叫“霾”?表声的“貍”是否也有什么特殊含义?
《字汇补·雨部》说:“霾,与埋通,瘞(yì,掩埋)也。”“霾”之尘土蔽物,有似掩埋,所以古籍多有借作“埋”的,如《楚辞·国殇》中“霾两轮兮絷四马”之“霾”。“霾”与“埋”是可以互相通用的。“貍”现在的读音是lí,是“狸”的异体字,指一种野猫。原来的读音为mái。原来,表示掩埋义的汉字,最初并非“埋”,而是“貍”。据说,“貍”之有“埋”义,是因为野猫善于藏伏的缘故。后来,又另造“埋”字,于是“貍于草中”就变为“埋于土中”,“埋”也由此替代了“貍”,而成为表掩埋义的规范字。
就“霾”字而言,之所以借“貍”表声,恐怕也是因为“貍”原有的掩埋义,与“雨尘”义相近的缘故吧。
(选自《咬文嚼字》,略有删节)
【1】下列关于原文内容的表述,不正确的一项是( )
A.霾是一种天象,它不仅毫无美感,而且由于人为因素的介入,一直被认为是一种污染。
B.新修订的《环境保护法》已涉及关于如何治理雾霾的问题,由此可见,雾霾已严重危害到了人们的身体健康。
C.霾习惯上也叫阴霾、灰霾或烟霾,霾的这些称号与霾给人的视觉感受有很大关系。
D.“雾霾”是个新词,在以前的词典中见不到它。但“雾霾”近来频繁见诸报端,并在2013年成为年度热词。
【2】下列理解和分析,不符合原文意思的一项是( )
A.雾与霾虽然同是自然天象,但有所不同,其主要区别就在于雾柔美朦胧神秘而霾没有雾的这种美感。
B.热词“雾霾”与旧词“霾雾”,虽然只有次序的颠倒,但词义重心却因此起了较大的变化。
C.“霾雾”是“夹杂有尘的雾”,中心词是“雾”,“雾霾”则是“像迷雾一样的霾”,中心词成了“霾”。
D.“霾”在甲骨文中就已屡见,卜辞有“癸卯卜,王占曰,其霾甲辰”的记载。这说明“霾”在商代就影响到人们的生活了。
【3】根据原文内容,下列理解和分析不正确的一项是( )
A.《尔雅》《康熙字典》乃至20世纪初编成的《中华大字典》,它们对“霾”的释义几乎是一样的。
B.《晋书·天文志》说:“凡天地四方昏濛若下尘,十日五日已上……雨不沾衣而有土,名曰霾。”这句话意思是说,“霾”尽管持续时间长短不同,但尘土中夹杂着未能湿透衣服的小雨。
C.“霾”是个形声字,义符为“雨”,说明是一种天象,声符为“貍”,说明“霾”的读音。
D.“霾”借“貍”表声,除了取其声音外,也可能是因为“貍”有掩埋义,与“雨尘”义相近的缘故。
