干旱河床拆“盲盒”

李全忠

干旱導(dǎo)致歐洲河流干涸，多瑙河的水位降到了過去近一個(gè)世紀(jì)以來的最低水平，埋葬在多瑙河深處的十幾艘德國艦船殘骸露出水面。

1 From the depths of the big Danube River， the huge? wrecks? （沉船）? of? more? than? a? dozen? German ships have risen once again， exposed by a drought that has starved Europes rivers and led to some of the lowest water levels of the past century. The exposed wrecks had been on the rivers bottom for nearly eight decades and emerge only when the water level is extremely low. The spread of an extraordinarily hot and dry summer across Europe has dropped water levels suddenly， creating a danger for local river transport and fishing on the Danube River.

2 More broadly， the high temperature weather has caused alarm across the continent as heat waves have increased at a faster rate， with scientists pointing to global warming and other factors as playing major roles.

3 The extreme temperatures have led to lower harvests and restricted Europes ability to create its own energy supply. They have reduced hydropower （水力發(fā)電） in Norway and threatened nuclear reactors in France. Britain banned the use of outdoor hoses （水管） after England experienced its driest July since 1935. In Spain， towns in Andalusia have restricted water usage. In Germany， environmentalists are concerned that dried?up lakes and rivers in the center of the country threaten the survival of fish and other wildlife. The drought has also brought more interest in relics dating back thousands of years that sometimes surface as water levels drop in rivers across Europe.

4 The foundations of a 2，000?year?old bridge in Rome emerged in the Tiber River this summer. In Spain， the Dolmen of Guadalperal， a four?to?five?thousand?year?old monument often compared to Stonehenge， rose from the waters west of Madrid. Earlier， a village in Spain， which had been abandoned and flooded when artificial reservoirs （水庫） were built in the 1960s， became visible after years under water.

5 So?called hunger stones also resurfaced as rivers ran low. When water levels dropped， the local populations knew the harvest would be bad and the following year would be tough.

Ⅱ. Difficult sentence

The drought has also brought more interest in relics dating back thousands of years that sometimes surface as water levels drop in rivers across Europe. 這場(chǎng)干旱也使人們對(duì)（其歷史能夠）追溯到數(shù)千年前的歷史遺跡產(chǎn)生更大的興趣，這些遺跡有時(shí)會(huì)隨著歐洲河流水位的下降而露出水面。

【點(diǎn)石成金】本句是一個(gè)主從復(fù)合句，句中的dating back thousands of years是現(xiàn)在分詞短語作后置定語，修飾前面的relics；that 引導(dǎo)定語從句，修飾先行詞relics；as引導(dǎo)時(shí)間狀語從句。
