19、这个问题后发现，当天气变暖，附近的玉垒山山顶上的冬雪开始融化时，河水经常泛滥。最简单的解决办法是建一座大坝，但这会毁了岷江。因此，李冰设计了一系列建在玉垒山不同高度处的渠道，它们在泄洪的同时能够使河流自然流淌。更甚者，多余的水可以直接送到干旱的成都平原，使之适合种植。在玉垒山的坚硬岩石上开凿渠道是一项了不起的成就，因为那时还没有火药和炸药。李冰找到了另一个解决办法。他结合使用火、水技术来加热和冷却岩石，直到它们裂开， 可以移动。经过八年的奋战，20米宽的沟渠在山上凿成了。这个水利系统一完工，就再也没有洪灾发生，人民由此能够安居乐业。如今，都江堰受到了来自世界各地科学家的赞赏，因为它有一个特点：

20、不像现代的水坝，水会被一堵巨大的墙堵住，都江堰仍然允许水自然流经岷江，使生态系统和鱼类种群和谐共存。词汇积累：阅读训练参考答案：1.

B细节理解题。根据第二段最后一句话“They studied the problem and discovered that the river most often overflowed when winter snow at the top of the nearby Mount Yulei began to melt as the weather warmed.”可知，岷江洪水泛滥是由附近山顶的积雪在天气转暖时融化导致。故答案为B。3. C细节理解题。根据第四段第三句“He used a combination of fire and water to

22、 heat and cool the rocks until they cracked and could be removed.”可知，李冰是结合使用加热石头和用水冷却的技术使石头爆裂成小块，从而移开大石。故答案为C。4. A推理判断题。根据最后一段的“Today, Dujiangyan is admired by scientists from around the world because of one feature. Unlike modern dams where the water is blocked with a huge wall, Dujiangyan still lets water flow through the Minjiang River naturally， enabling ecosystems and fish populations to exist in harmony.”可知，都江堰至今都受到全世界科学家的敬佩，是因为都江堰采用疏导的方式让水从岷江自然地流出，保证了生态系统和鱼群和谐共存。故答案为A。变式训练1&2参考答案见短文学科网（北京）股份有限公司
