Most of you may think of clams (河蚌) as part of a big meal. But these little things can do a more important job: testing (检测) the cleanness of people’s drinking water!
The main water station in Poland (波兰), gives water for millions of people there. They make eight clams test the drinking water. Because clams have an amazing sense of finding water pollution. If the water is not clean enough, they close their shells (壳). So, the water station got the clams and connected their shells to a computer system. When four or more clams close their shells at the same time, an alarm (警报) will make a sound.
Clams will get used to (习惯) dirty water in several months, so they only work for three months. People will get new clams to take over the job. The water station said this could work well to test water quality (质量).
