题目内容
March 20th is World Water Day every year. According to a report from the United Nations, more than half of the world's major rivers have serious water loss and are polluted.
The Yellow River, the world's fifth longest river, watered some of the oldest farms on earth. But now it has a serious problem. 小题1: In most of the past 35 years, it didn't reach the sea.
The Nile in Egypt, running 6, 650 km, is the longest river in the world. 小题2:Now it is down to 2 billion m' or so. Australia's Murray River reaches the sea only every other year. One fifth of America's Rio Grande has no water, either.
____小题3:
Mostly it's damming (筑坝) and global warming that make rivers dry.
____小题4: Now about 45, 000 of them lie across the world's rivers. They hold back around 15% of the world's fresh water from running to the sea.
Global warming is making things worse. Warmer weather takes water away. The glacier (冰川) are becoming smaller. 小题5: Global warming has had certain effects on water sources (源头). Droughts (干旱) happening around the world make people pay more attention to this fact.

文章大意:每年的3月20日是世界水日。根据美国的一个报道,世界上有一半多的主要河流严重缺水或被污染。黄河,世界上第五大河,在过去的35年里,就没有流到大海里。同意,埃及的尼罗河,世界上最长的河流,由原来每年的32000000000平方米的流量降低到2000000000.等等。是说明原因造成这样的现象?主要是由于筑坝和全球变暖导致河流干涸。
