【正文】 hey had to edge their way along this, sometimes wading across shallow streams, or swimming across deep pools. Suddenly they came to a waterfall which dropped into an underground lake at the bottom of the cave. They plunged into the lake, and after loading their gear on an inflatable rubber dinghy, let the current carry them to the other side. To protect themselves from the icy water, they had to wear special rubber suits. At the far end of the lake, they came to huge piles of rubble which had been washed up by the water. In this part of the cave, they could hear an insistent booming sound which they found was caused by a small waterspout shooting down into a pool from the roof of the cave. Squeezing through a cleft in the rocks, the potholers arrived at an enormous cavern, the size of a huge concert hall. After switching on powerful arc lights, they saw great stalagmites—some of them over forty feet highrising up like treetrunks to meet the stalactites suspended from the roof. Round about, piles of limestone glistened in all the colours of the rainbow. In the eerie silence of the cavern, the only sound that could be heard was made by water which dripped continuously from the high dome above them. 【課文翻譯】 洞穴勘查——或洞穴勘探——是一項(xiàng)比較新的體育活動(dòng)。尋求獨(dú)處的愿望或?qū)で笠馔獍l(fā)現(xiàn)的機(jī)會(huì)的欲望吸引人們來(lái)到地下深處。要想對(duì)洞穴探險(xiǎn)者的動(dòng)機(jī)作出滿意的解釋是不可能的。對(duì)洞穴探險(xiǎn)者來(lái)說(shuō)，洞穴有一種特殊的魅力，就像高山對(duì)登山者有特殊魅力一樣。為什么洞空能引發(fā)人的那種探險(xiǎn)本能，人們對(duì)此只能有一種模模糊糊的理解。 探測(cè)非常深的洞穴不是那些在星期日下午漫步的人所能勝任的。這種活動(dòng)需要有軍事行動(dòng)般的周密布署和預(yù)見(jiàn)能力。有時(shí)需要花費(fèi)整整 8天時(shí)間來(lái)搭起繩梯，建立供應(yīng)基地，然后才能到一個(gè)很深的洞穴里。作出這樣的準(zhǔn)備是必要的，因?yàn)闊o(wú)法預(yù)見(jiàn)到洞穴探險(xiǎn)者究竟會(huì)遇到什么性質(zhì)的困難。，深達(dá)3,723英尺。這個(gè)深邃的洞穴是由一條地下暗泉沖刷巖石中的縫隙并使之慢慢變大而形成的。此洞的洞口在丹芬阿爾卑斯山的高原上，僅 6英尺寬，很難被發(fā)現(xiàn)。若不是法國(guó)洞穴探險(xiǎn)家伯杰由于偶然的機(jī)會(huì)發(fā)現(xiàn)了這個(gè)洞口的話，這個(gè)洞也許不會(huì)為人所知。自從被發(fā)現(xiàn)以后，這個(gè)洞成了洞穴探險(xiǎn)者的珠穆朗瑪峰，人們多次進(jìn)入洞內(nèi)探險(xiǎn)，但至今尚有不少東西有待勘探。 最近。他們從高原上的窄縫進(jìn)去，順著筆直陡峭的洞壁往下爬。來(lái)到一條狹窄的走廊上。他們不得不側(cè)著身子往前走，有時(shí)過(guò)淺溪，有時(shí)游過(guò)深潭。突然，他們來(lái)到一道瀑布前，那瀑布奔瀉而下，注入洞底一處地下湖里。他們跳入湖中，把各種器具裝上一只充氣的橡皮艇，聽(tīng)任水流將他們帶往對(duì)岸。湖水冰冷刺骨，他們必須穿上一種特制的橡皮服以保護(hù)自己。在湖的盡頭，他們見(jiàn)到一大堆一大堆由湖水沖刷上岸的碎石。在這兒，他們可以聽(tīng)見(jiàn)一種連續(xù)不斷的轟鳴聲。后來(lái)他們發(fā)現(xiàn)這是由山洞頂部的一個(gè)小孔里噴出的水柱跌落到水潭中發(fā)出的聲音。洞穴探險(xiǎn)者從巖石縫里擠身過(guò)去，來(lái)到一個(gè)巨大的洞里，其大小相當(dāng)于一個(gè)音樂(lè)廳。他們打開(kāi)強(qiáng)力弧光燈，看見(jiàn)一株株巨大的石筍，有的高達(dá)40英尺，像樹(shù)干似地向上長(zhǎng)著，與洞頂懸掛下來(lái)的鐘乳石相接。周圍是一堆堆石灰石，像彩虹一樣閃閃發(fā)光。洞里有一種可怕的寂靜，的可以聽(tīng)見(jiàn)的聲響是高高的圓頂上不間斷地滴水的嘀嗒聲。
