For the past weeks, melting snow and heavy spring rains have caused the Missouri River to rise above normal levels, flooding parts of Iowa, Nebraska, Missouri, and South Dakota. Thousands of people have been forced to leave their homes to escape the flood.
The Missouri River is the second longest river in the United States. It is the longest river that feeds into the Mississippi River. Residents in areas along the Missouri River have been building temporary levees(防洪堤) along the river. They hope that the levees will prevent the river water from overflowing. On Monday morning, however, several levees in northern Missouri broke.
Because of the broken levees, the Missouri River came close to forcing the shutdown of nuclear power plant(核电站) in Brownville, Nebraska. There, the river rose to 900.5 feet. If it had risen 18 more inches, officials would have been forced to close the plant for safety reasons.
This nuclear plant had been preparing for possible flooding since May 30th. Workers used over 5,000 tons of sand to construct barricades around the plant. Luckily, the river stopped rising in time and the plant remained open. “We knew the river was going to rise for some time,” Nebraska Public Power District spokesman Mark Becker said. “It was just a matter of when.”
Engineers and weather forecasters predict that the river will rise as much as five to seven feet above flood level in Nebraska and Iowa and up to ten feet above the level in Missouri. They think the river will stay high until August. The US government has agreed to give 1 billion in emergency money to repair broken levees and areas damaged by the flooding along the Missouri and Mississippi rivers.
5. What is the primary purpose of the temporary levees built by residents?
A. To collect rainwater.
B. To stop river water from overflowing.
C. To generate electricity.
D. To offer a walking path for residents.
6. What can be inferred about the preparation efforts at the nuclear power plant in Brownville, Nebraska?
A. They took measures to prevent flooding.
B. They were confident the river would not rise.
C. They didn’t make any preparations but waited.
D. They ignored the warnings about the rising river.
7. What conclusion can we draw from the last paragraph?
A. Nebraska’s flooding is expected to be worse than Missouri’s.
B. The increase in river levels will have little effect on nearby areas.
C. The US government’s response showed the serious outcome of the floods.
D. Experts are quite confident that the flooding will come to an end in August.
8. What’s the main idea of this passage?
A. The impact of the flood on a nuclear power plant.
B. The actions taken by the US government in the face of flood.
C. The connection between the Missouri and Mississippi rivers.
D. The flooding and damage caused by the rising Missouri River.

答案
5—8 BACD
B
【语篇解读】这是一篇新闻报道。文章主要报道了密苏里河水位上涨造成了洪水和严重的破坏。
5. B 细节理解题。根据文章第二段“They hope that the levees will prevent the river water from overflowing.”可知，居民们修建临时堤坝的主要目的是防止河水泛滥。故选 B。
6. A 推理判断题。根据第三段提到的“This nuclear plant had been preparing for possible flooding since May 30th. Workers used over 5,000 tons of sand to construct barricades around the plant.”可知，该核站的工人使用了超过 5000 吨的沙子来建造围绕电站的屏障。这些信息表明，核电站采取了措施来阻止洪水。故选 A。
7. C 推理判断题。根据文章最后一段“The US government has agreed to give 1 billion in emergency money to repair broken levees and areas damaged by the flooding along the Missouri and Mississippi rivers.”可知，美国政府的反应显示了洪水造成的严重后果，需要政府的紧急响应和资金支持。故选 C。
8. D 主旨大意题。通读全文，尤其是第一段“... the Missouri River to rise above normal levels, flooding parts of Iowa, Nebraska, Missouri, and South Dakota. Thousands of people have been forced to leave their homes to escape the flood.”可知，文章主要讲述了密苏里河水位上涨造成了洪水和严重的破坏。故选 D。
