(1)Yellowstone National Park is in the western state of Wyoming. It is one of the most unusual places in the world. Extremely hot water shoots out of the ground in several hundred places. Small lakes contain water that is so hot it is dangerous to come too close.
(2)Visitors can watch bubbles coming up through boiling hot mud. They can see rocks that were once liquid and have cooled into strange shapes.
(3)Yellowstone is built on an ancient volcano. A lake of hot liquid rock is about six kilometers under the park. This lake is about sixty-five kilometers wide. Experts say this lake is under huge amounts of pressure. The pressure and heat cause hot water to shoot out of the ground and mud to boil at Yellowstone.
(4)Yellowstone National Park is the oldest national park in the world. About three million people visit it each year. Its great natural beauty has made it one of the most popular national parks.
(5)Most visitors like to see "Old Faithful," the world’s most famous geyser. A geyser shoots hot water high into the air. There are more than three hundred geysers in Yellowstone.
(6)Old Faithful is not the biggest or the most beautiful geyser. But it is the most popular. Visitors gather around Old Faithful before each eruption. Experts at the park are able to predict when these will happen. The average time between eruptions is about ninety minutes. Old Faithful shoots water an average of forty meters into the air. This eruption lasts between two and five minutes. Old Faithful releases up to about thirty thousand liters of water into the air each time.
(7)The hot spot deep under the ground produces geysers like Old Faithful. Old Faithful is evidence of the volcanic activity at Yellowstone. But will the Yellowstone volcano erupt again? Most experts think the answer is yes. But no one knows when. The most recent of the three extremely powerful eruptions was about six hundred fifty thousand years ago.
(8)Experts say at least thirty smaller volcanic eruptions have taken place at Yellowstone. Some of these were perhaps as big as the nineteen ninety-one eruption at Mount Pinatubo in the Philippines. Several are believed to have been much larger. The most recent of these smaller eruptions took place about seventy thousand years ago.
(9)Volcano experts say it is extremely difficult to tell when Yellowstone might become an active volcano again. However, earthquakes near a volcano are usually good evidence that a volcano might become active again. For example, Mount Saint Helens in the northwestern state of Washington exploded in nineteen eighty. Several earthquakes took place near the volcano before that time. On the morning that it exploded, Mount Saint Helens experienced an earthquake of five point one on the Richter scale.
(10)Yellowstone National Park experiences several thousand earthquakes each year. Most are very small. They cannot be felt. They can only be measured by scientific instruments. However, in August of nineteen fifty-nine, an earthquake at Yellowstone measured seven point five on the Richter scale. Twenty-eight people were killed.
(11)It was one of the strongest earthquakes ever recorded in the United States. But Yellowstone’s sleeping giant volcano did not erupt.
(12)In two thousand one, the United States Geological Survey, Yellowstone National Park and the University of Utah signed an agreement.
(13)That agreement established the Yellowstone Volcano Observatory. Under the agreement, the park, the Geological Survey and the university are responsible for improving efforts to study the volcanic system of Yellowstone.
(14)The observatory uses information from many different instruments on the ground and from satellites to study the volcano. The information will help officials warn the public once if Yellowstone’s huge volcano shows any sign of eruption.
(15)Experts at the observatory say Yellowstone represents some danger to the public. It always has. However, its natural beauty also makes it a treasure that could not be possible without the sleeping giant volcano that is under Yellowstone National Park.
What is true about the volcanic eruption in Yellowstone?
选项
A、Experts predict that volcanic eruption is unlikely to happen recently.
B、There are at least 30 small volcanic eruptions every year.
C、The volcanic eruptions can be compared to that at Mount Pinatubo.
D、There have been three extremely powerful volcanic eruptions so far.
答案
D
解析
根据题干中的volcanic eruption in Yellowstone定位到第7至9段。从第7段最后一句可推断D的说法正确。最具干扰性的是C,将其与第8段第2句相比,可发现原文该句开头的Some of these是指“一些较小规模的火山喷发”,这与C的主语The volcanic eruptions所指范围显然不同。
