The solution to the heavily contaminated water in New York City, US, may be located beneath the wate
英语试题 07-05
The solution to the heavily contaminated water in New York City, US, may be located beneath the water’s surface: oysters (牡蛎).
We searched the New York Public Library and found that the Hudson River had a flourishing (繁盛的) oyster population around 100 years ago, but over-farming and pollution from the city nearly wiped it out. Now, with the help of organizations across New York City, the oyster population is beginning to make a comeback, which could have a positive impact on the river.
The Hudson River still faces major sanitation challenges. According to a 2018 report released by the New York State Department of Environmental Conservation, 6.25 billion gallons of sewage (污水) entered New York’s waterways between 2017 and 2018.
The primary cause of sewage pollution, the report found, is the runoff caused by rain and snow that bypasses the preventative measures in treatment plants and manholes (检修孔).
Despite this, in the past two decades, oysters have begun to reappear due to actions being taken by organizations like The River Project and assistance from local volunteers. Oysters act as filters and can clean up to 50 gallons of water each day, according to the Chesapeake Bay Foundation. Leaders of the organizations hope that by bringing back the oyster population, they’ll also bring back the clean waters of a pre-industrial era.
To better help educate the public, these organizations are hosting canoe trips and inviting people in the community to come and see the oysters living in the canal. The more the city sees people using the canal, the more likely it may be to fund the oyster program.
For the local people, bringing back oysters restores the hope that other species would thrive there too. Diversity within an ecosystem makes it more sustainable, with each species playing a role that other species depend on for survival. Each creature in an ecosystem has a role to carry out.
32. What caused the population of oysters in the Hudson River to decrease over 100 years ago?
A. Climate change and dry weather.
B. Over-farming and pollution.
C. Overfishing and natural disasters.
D. Overpopulation and imbalanced ecosystem.
33. What is the major cause of sewage pollution in the Hudson River, according to the 2018 report?
A. The untreated runoff caused by rain and snow.
B. The sewage from the neighborhood.
C. The lack of treatment plants and manholes.
D. The decrease of the oyster population.
34. What is the main idea of the second-to-last paragraph?
A. How to organize canoe trips.
B. How the oyster program started.
C. How the organizations remind the public of the canal’s beauty.
D. How the organizations raise people’s awareness of environmental protection.
35. What is one benefit of an increase in oyster population according to the article?
A. It can reduce the usage of pesticides.
B. It can bring economic benefits.
C. It can help control the number of harmful creatures in the water.
D. It can help maintain diversity within the local ecosystem.
