上一題
The melting waters of the Ruwenzori Mountains feed the headwaters of the Nile. Here, for hundreds of thousands of years, people have depended on the river for basic necessities: water, transportation, farming, and fishing.
Now, the glaciers of the Ruwenzori are melting so rapidly that they will soon disappear. Within the next twenty or thirty years, most glaciers in Africa and South America will vanish completely.
The shrinking of the world’s glaciers will have massive consequences for communities that depend on ice melt. In the short-term, these consequences may appear beneficial. For example, extra water from glaciers means that hydroelectric dams will run at maximum power. In the long run, however, the melting of earth’s glaciers could be catastrophic. Today’s extra hydroelectric power has been stolen from the future. Communities with ample power now may have none after the glaciers have melted, and the loss of ice will increase sea levels worldwide.
Temperature change and a lack of snow is causing the retreat of the glaciers. Glaciers are no longer getting built up during the snowy winter months, so they are no longer able to maintain their size over the long run.
Unless there are some changes in the current rate of global warming, the glaciers are essentially doomed.
【題組】What is the main idea of this passage?

(C)Temperature change and a lack of snow causes the decrease of glaciers.
(D)The melting of glaciers is potentially disastrous to human beings.

答案：D

Ruwenzori山脈的融化水域滋養了尼羅河的源頭。 在這裡，數十萬年來，人們一直依靠河流來獲得基本必需品：水、交通、農業和漁業。

現在，Ruwenzori的冰川正在迅速融化，很快就會消失。 在未來二十或三十年內，非洲和南美洲的大多數冰川將完全消失。

世界冰川的萎縮將對依賴冰融化的社群產生巨大後果。 在短期內，這些後果可能看起來是有益的。 例如，冰川的額外水意味著水力發電壩將以最大功率執行。 然而，從長遠來看，地球冰川的融化可能是災難性的。 今天額外的水力發電是從未來偷來的。 冰川完全融化後，現在擁有充足電力的社群可能會一個不剩的（消失），冰的融化將使全世界的海平面上升。

溫度變化和缺雪導致冰川退縮。 在下雪的冬季，冰川不再積累，因此從長遠來看，它們不再能夠保持其大小。

除非當前全球暖化速度發生一些變化，否則冰川基本上註定要毀滅。
