Eco-friendly (环保) rain gardens have beautiful flowers, trees and other plants that beautify the community. They are also healthy for the environment and the people living and working nearby. A rain garden is not very different from a traditional garden. It is just far more eco-friendly. Usually it is built lower than the ground.

Why Eco-friendly Rain Gardens Are Recommended

Rain gardens smartly used rain and storm water by temporarily (暂时) holding water from rain and storms and letting it soak (渗透) slowly into the ground before it runs into streams or enters the public drinking water supply. In this way, a rain garden keeps the water, allowing it to be used as needed by plants in the rain garden, rather than flowing (流) directly into nearby streams and going unused. The water will soak, slowly into the ground within a day or two. This creates an advantage that the rain garden does not allow mosquitoes (蚊子) to breed (繁殖) . This is a simple, attractive, and eco-friendly “green” way to treat storm water.

What’s more, planting a rain garden helps cut down on pollution and make the environment better. The gardens don’t use expensive machinery and chemicals. They remove harmful chemicals in the rainwater and reduce the amount of pollution reaching streams and rivers by up to 30 %.

How to Build Your Own Rain Gardens

Native (本地的) plants are recommended for rain gardens because they are more used to the local climate (气候), soil, and water conditions. They may attract local wildlife such as native birds. Water your rain garden right after planting and once a week. Don’t water it if you have had at least an inch of rain during the week. You needn’t take much care of it once the plants have a necessary root system (根系统) .

Often, local governments and private businesses develop large rain gardens in their yards and in public parks, However, you can do your own part. You don’t need to be an environmental engineer to create a rain garden, Just start by building smaller rain gardens in your yards.

【答案】1. built   2. Advantages   3. smart  4. entering  5. prevent/stop/keep

6. improve  7. without   8. wildlife 9. unless   10. engineer
