Kindles, Nooks and other e-readers are threatening the future of printed books. But reading itself may get a boost from the devices. For example, a study found that the kids felt better about reading after a course in which they used Amazon Kindles. The research is in the _International Journal of Applied Science and Technology._

For two months, 199 middle-school students in a reading improvement class in Texas had 15 to 25 minutes every day when they were free to read on the Kindle. In general, the students felt the device improved their reading ability. And they tended to enjoy using an e-reader.

They noted the ease of carrying multiple books in one device, and the feeling that reading was suddenly a high-tech 21st-century activity rather than a boring waste of time. And some low-level readers who might otherwise be embarrassed to be seen with a simple book liked keeping their peers in the dark about what title they were reading. In the old days, one had to use a fake book-cover to achieve that level of secrecy.

A rain garden is not very different from a traditional garden. It is just a far more eco-friendly 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(渗透) 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 eco-friendly “green” way to treat storm water.

What’s more, planting 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 recommended for rain gardens because they are more used to the local climate, 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 native plants establish the necessary root system，they 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 professionally environmental engineer to create a rain garden. As long as you’re eco­conscious homeowners，you can help the environment by building smaller rain gardens in your yards.
