Last Sunday, my family went for walk in a nearby park. We wanted to breathe the fresh air and having fun there. However, when gone out, we found it was cloudy and smoggy (烟雾弥漫的). Only a few people were walking quick on the streets wearing their masks. I was wondering what was the matter when my little brother begins to cough loudly. Suddenly I realized that it was air pollution. So we had to go back to home that day. Smoke from cars, buses, and factories make the air dirty, that is harmful to our health. I think they all should do some thing to keep the air clean.

   Caroline Solomon was on her high school's swim team. But at times she could not go into the creek(小溪)near her home. It was simply too polluted. "I decided I wanted to do something about it,"she recalls. So she studied environmental science and public policy at Harvard University in Cambridge. Later,she went to graduate school. Some of her classes could be challenging,though,since she couldn't hear her teachers. "I've been deaf since I was 15 months old,"Solomon notes.

Today she teaches biology at Gallaudet University in Washington,DC. She has no trouble communicating with her students. They,too,are primarily deaf or hard of hearing. That's why all classes at Gallaudet are taught in American Sign Language. Solomon also has an active life outside the classroom. She especially enjoys hiking,biking and other activities with her family.

Her research takes her to the Anacostia River. "It is very close to Gallaudet,and I easily bring my students there,"she says. Water running through local forests and marshes drains into this river,so does water running off urban streets,golf courses and industrial sites." The river's watershed(流域)kind of concentrates all the things that happen when humans mess with the natural landscape,"she explains. Not surprisingly,this river has developed a reputation for being quite polluted.

Solomon has been focusing on how pollutants affect tiny organisms that form the base of the river's food web. "I am now looking at the bacteria population," she says,"to see what types there are."

Solomon wants to see more students who are deaf or have other disabilities make a difference in environmental science and other fields. As she often says, "If I can do it, you can do it."
