英语试题 01-16
The running buffalo clover(a plant) used to spread across eight states, from Virginia to Arkansas. The more it was walked on by the buffalo the better it grew.
When buffalo disappeared, the plant was gone, too. Researchers believed the plant was extinct, which had not been spotted since 1940s—until a population was found in West Virginia in 1983. Now, after decades of protection, the small plant stands to be removed from the list of species protected under the Endangered Species Act.
Biologist Rodney Bartgis came across a patch of running buffalo clover in 1983. He was recording plants in West Virginia and was wandering around a car road in the New River Gorge when he spotted some “unique-looking” leaves, which he recognized as running buffalo clover. After the finding was confirmed, the clover was considered no longer extinct and placed on the endangered-species list in 1987.
Part of the reason it took a while to start to find the clover in the wild is that, unlike other rare plants, this one won't grow in unspoiled areas. It likes being run over. When the clover was first discovered, US Fish and Wildlife Services(USFWS) forest managers were told to avoid driving in the area populated by the plant. But this made the clover there disappear. In the Fernow Forest in West Virginia, Gundy, a research forester, realized the skidders used to pull trees had helped ensure the clover's growth before anyone knew it was there. So in her work monitoring the population in Fernow, Gundy runs over the clover with a skidder. "You need to remember to agitate it,“ she says.
Since 1987, researchers have found 154 populations. But it's not out of the woods yet. The clover still faces threats from invasive species. The USFWS will have a public comment period, when the clover's case for delisting will be reviewed. Even if it is delisted, biologists from the USFWS will observe populations for years closely to ensure that the species is secure.
8. What do we know about the running buffalo clover from the first two paragraphs?
A. It has died out due to some human action.
B It still needs careful protection from extinction.
C. It was considered extinct before its rediscovery.
D. It can grow better without buffalo stepping on it.
9. What do we know about Rodney Bartgis from the text?
A. He discovered the clover by accident.
B. He noticed the clover in an unspoiled area.
C He hardly recognized the clover when first seeing it.
D. He had searched for the clover for years before finding it.
10. How should we deal with the buffalo clover according to what Gundy said in paragraph 4?
A. She advised we should keep away from it. B. She suggested we should disturb it.
C. She told us to remember to water it often. D. She asked us to plant more and more buffalo clover.
11. What can we infer from the text?
A The buffalo ate up the clover in the US.
B. The clover is almost free from natural enemies.
C. The USFWS is cautious of the protection of the clover.
D. The clover won't be removed from the protection list.
