A rain garden is not very different from a traditional garden. It is just a far more ecofriendly garden. Usually it is built lower than the ground. Rain gardens make smart use of rain and storm water by temporarily holding water from rain and storms and letting it soak（浸人） slowly into the ground before it runs into streams or enters the public drinking water supply. Thus, a rain garden keeps the water, allowing it to be used as needed by plants in the rain garden, rather than flowing immediately 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 to breed. This is a simple, attractive, and ecofriendly “green” way to treat storm water. What’s more, pl anting a rain garden helps reduce pollution and improve the environment. Without using expensive machinery and chemicals, rain gardens remove harmful chemicals in the rainwater and cut down on the amount of pollution reaching streams and rivers by up to 30%. Native plants are remended for rain gardens because they are more used to the locals climatem, soil, and water conditions. They may attract local wildlife such as native birds. Water your rain garden immediately after planting and once a week, unless you have had at least an inch of rain during the week. Once the native plants establish the necessary root system, it will require little care. Often, local governments and private businesses develop large rain gardens in their yards and in public parks as a way to improve the environment and solve flooding problems. However, you don’t need to be a professional environmental engineer to create a rain garden. As long as you’re eco conscious homeowners, you can help the environment by building smaller rain gardens in your yards. 55． Which of the following is the ecofriendly function of rain gardens discussed in Paragraph 4?

S. town of Joplin, Missouri, say the death from Sundays’ big tornado reaches 116 and that search efforts continue for possible survivors trapped in rubble (碎石 ). Search and rescue teams are conducting their third sweep through the nearly 10 kilometer – long and one – kilometer wide area of destruction left by the tornado. They are working as quickly as possible while weather conditions remain relatively stable. More storms are forecast for the erea. Joplin Fire Chief Mitch Randles said there are areas with large piles of rubble that might hold survivors. “We are still finding individual s. We did rescue seven individuals from underneath rubble yesterday and , of course, we are also finding dead folks as well.” Said mre folks and that is why we are doing these searches. We want to make every opportunity that we can to find everybody that is in the rubble and that has survived to this point.” Randles said the current sweep involves a slower pace that previous searches and that he plans a fourth search, possibly on Wednesday, using specially trained dogs. “
