   Many years ago, when I was in high school and working weekends to pay for the extras that my family couldn’t really afford, I lost my wallet.

My old car needed gassing up in the back. I prepaid and then put my wallet on the bumper(保险杠), and drove off. I hadn’t even had time to miss it when my phone rang and a man asked me if I had lost my wallet. I checked my pocket and to my surprise, I didn’t find my wallet. He asked me to tell him how much money was in it. He then told me where to pick up my wallet.

As I pulled into his driveway, I noticed his handicapped van(残疾人车) and the ramp(斜坡) going up to the house. I was thinking that this man must have had difficulty in getting out of his van and getting my wallet off the street. He had to pull over, get in his wheelchair, lower the lift, and then pick it up. I was just surprised. I felt grateful.

I knocked on the door and he told me to come in. I thanked him about 10 times for finding my wallet. I was stuck, though. While I didn’t want to insult him by offering money, I really felt like offering something. So I asked him if there was anything I could do to repay his kindness, and he said, “Just pass it on.” I said I would be certain to do that. I was raised to be honest in any circumstance and I would have done so, without promising this fellow I would, but I wanted to repay his kindness, so I willingly promised I would.

   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."

In our life, everyone is surely to have difficulties. It is the same with me. I still remember how worried I am about my English learning three years ago. I had difficulty follow my teacher in the English class. With my classmates often laughing at me because of my poor English, I decided to do anything. Firstly, I took a part in the English Corner that I met many friends. They shared their methods of learning English with me. Beside, I also found it useful keep English diaries. What’s more, I talked with friends on the Internet and exchanged emails with English. As a result, I made great progresses in learning English.
