细节题
Beavers (海狸), like humans, change their surroundings to fit their needs. Known as nature’s engineers, they tear trees down to build homes to live in and dams to raise water levels for protection from enemies. Dams also slow water’s flow while blocking sediment (沉积物) that would otherwise flow downstream. The resulting wetlands often attract wildlife diversity where none had existed. There are challenges, though. Beaver dams sometimes cause flooding, and most people prefer trees alive and upright.
Communities face a delicate balancing act, learning to coexist with beavers. Last winter, many people enjoying Winston Path became beaver fans as one furry family transformed Swallow Pond into an oasis for birds, frogs, turtles and deer.
Yet such activity caused concern. As beavers worked, they raised water levels about five feet. The increased depth allows beavers to survive underwater if the pond ices over. But county officials were concerned about how higher water would affect the soil bank supporting Winston Path.
To find a good balance between protecting the path and the beavers, the county introduced a “beaver baffle”—a pond leveler. Beavers often rush to fill holes in their dams. Baffles stabilize water levels by creating a hidden exit for high water to escape through the dam, unnoticed by the beavers.
People love the beavers but they also love the mature trees. Recently, Catherine Jones, 18, organized a tree-caging event—putting wire cloth around large tree trunks to discourage beavers from biting them. It also protects people from injury due to random trees falling. “We cover the trees we don’t want them to eat, while planting periodically others they like,” said Jones. “We need to learn to give up a little of our wants to share the Earth’s resources.”
Swallow Pond’s 2023 project will restore proper water depth and improve wildlife habitat without creating problems for the path. The balancing act continues.
What is the first paragraph mainly about?
Where beavers’ favorite surroundings are.
","What effects beavers have on their habitat.
","Why beavers are called nature’s engineers.
","How beavers help attract wildlife diversity.
"]段落大意题。根据文章第一段 “Beavers (海狸), like humans, change their surroundings to fit their needs. Known as nature’s engineers, they tear trees down to build homes to live in and dams to raise water levels for protection from enemies. Dams also slow water’s flow while blocking sediment (沉积物) that would otherwise flow downstream. The resulting wetlands often attract wildlife diversity where none had existed. (海狸和人类一样，会改变周围的环境来满足它们的需求。他们被称为自然工程师，他们推倒树木建造房屋，建造水坝以提高水位以抵御敌人。大坝还减缓了水流，同时阻挡了原本会流向下游的沉积物。由此产生的湿地往往吸引了原本不存在的野生动物多样性。)” 可知，第一段主要讲海狸对它们的栖息地有什么影响。故选B。
Why did the beaver family’s activity cause concern?
Swallow Pond would flood often.
","Sediment would flow downstream.
","The popular path might be damaged.
","Beavers might have to live underwater.
"]因果细节题。根据第三段最后一句 “But county officials were concerned about how higher water would affect the soil bank supporting Winston Path. (但是县官员担心更高的水位会如何影响支撑温斯顿小路的土壤库。)” 可知，海狸家族的活动之所以会引起关注是因为受欢迎的小路可能会被破坏。故选C。
What do the underlined words “beaver baffle” refer to in paragraph 4?
A block to keep beavers away.
","A tool to fix holes in the dams.
","A device to maintain water level.
","A material to protect the soil bank.
"]词义猜测题。根据第四段最后一句 “Baffles stabilize water levels by creating a hidden exit for high water to escape through the dam, unnoticed by the beavers. (挡板通过创建一个隐藏的出口来稳定水位，让高水位从大坝中流出，而不被海狸发现。)” 可推知，划线的单词beaver baffle应该指的是一个维持水位的装置。故选C。
What is the theme of Swallow Pond’s 2023 project?
Biological diversity.
","Harmonious coexistence.
","Prevention of natural disasters.
","Preservation of wildlife habitat.
"]推断判断题。根据最后一段 “Swallow Pond’s 2023 project will restore proper water depth and improve wildlife habit at without creating problems for the path. (Pond’s 2023年项目将恢复适当的水深，改善野生动物的习性，而不会给路径带来问题。)” 可知，燕子塘2023年项目的主题是和谐共存。故选B。
