WetlandsHow are a bog, a marsh, and a swamp the same? They are all wetlands. A wetland is land that is very wet at least some of the time. Plants and animals live there. The crocodile lives in swamps in Florida. A yellow fly lives in bogs in England. This fly is called the “hairy canary.” People are working to save the wetlands. They try not to build houses on them. They also try not to build roads over them. Wild grass and birds and bugs live in wetlands. We must keep their homes safe. 湿地 bog、marsh和swamp有哪些相同处？它们都是湿地。 湿地是指至少在某些时候非常潮湿的土地。有动物和植物生活在那里。 鳄鱼生活在佛罗里达州的沼泽里。黄蝇生活在英国的沼泽里。这种苍蝇被称为“毛茸茸的金丝雀”。 人们正在努力保护湿地。他们尽量不在上面盖房子，也尽量不在上面修路。 野草、鸟类和昆虫生活在湿地里。我们必须保护他们的家。
