Rainwater in cities causes more troubles than wet feet. It carries away waste from rooftops and washes the streets to be very, clean, but when it washes the streets and other harmful pollutants, scientists are now trying to work out how to deal with flooding rainwater.
In the city of Wetshells, Belgium, researchers are experimenting with seashells. Millions of shells from the nearby North Sea are used to collect and treat rainwater from a shopping mall roof and a parking lot. The shells are laid below a surface drain (下水道) through which dirty water is carried away. With a 70% empty space that allows them to store rainwater, they are also a natural cleaning station, which is then used to water community gardens.
The experiment is part of a project called StopUP, whose goal is to prevent rainwater from carrying pollutants into lakes and rivers. The project's focus is to make sure that such wastewater, which can include everything from plastics to heavy metals, gets treated.
Thomas Jeffery, head of the College of Environmental Engineering in Germany, said a big knowledge gap can exist between the popular perception of rainwater and its true content. "Rainwater seems to be very clean, but when it washes the streets and other harmful pollutants," said Thomas full of dust and other harmful pollutants.
In Europe, 38% of surface water bodies have different forms of pollutants, which run deep in the ground and damage soils, plants and animals, according to Julie Rosalie, director of the European Environment Agency. Human health depends on clean water for drinking, bathing and cooking, and now we are at risk because plants and animals are affected by chemicals in rivers, lakes and coastal waters.
StopUP technologies and methods could provide tools to reduce rainwater pollution, " Rosalie said. "It has a positive effect on the quality of our common environment."
8. What are the seashells in the experiment used for?
A. Clearing the polluted rainwater.
B. Repairing a shopping mall.
C. Making gardens more attractive.
D. Carrying away waste in cities.
答案：A
解析：根據(jù)“The shells are laid below a surface drain through which dirty water is carried away...they are also a natural cleaning station”可知，貝殼被用來收集和處理雨水，起到清潔作用，A選項(xiàng)“凈化被污染的雨水”正確。B選項(xiàng)“修理購物中心”、C選項(xiàng)“使花園更有吸引力”、D選項(xiàng)“帶走城市的垃圾”均與貝殼的作用無關(guān)。
