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.

   Blind people can read. They do so by running their fingers along a line of raised points or dots on paper. Of course, they first have to learn the code（代码）. Here are some examples of it. One dot stands for the letter “A”. Two dots side by side mean “C”. Four dots arranged to look like a box（：：） stand for the letter “G”. By placing the dots in special patterns, all the letters of the alphabet can be formed.

This code was made up by a Frenchman called Louis Braille. Though he could see at birth, he became sightless when he was only three. Braille was cutting leather in his father’s shop. His knife slipped and cut his eye. Infection（感染）spread to both eyes, and he became blind.

At 10, he was placed in a home for the blind. But young Braille had great talent. He became a skilled musician and soon got a job as a church organist（风琴弹奏者）in Paris.

Because he had talent and was quick, he became a teacher at a school for the blind. While there, he heard that a captain had sent messages to his soldiers that they could read at night without light. His messages were in the simple form of raised dots and dashes. This was the clue Braille needed. At the age of 15, he worked out his own six-dot code. Each group of dots is called a cell. The cells are three dots high and two dots wide. For the rest of his life, Braille taught his young flock to read both written and musical works using his code.

For the last 17 years of his life, Braille was ill with tuberculosis. He died at the age of 43.

I was entering the underground parking lot when I heard a little girl shouted “Mama, Mama!” I looked around and saw the girl in a car alone. I went over to ask her how was the matter. She said she needed to go to the washroom badly. I tell the girl to get out and I would take him to the washroom. She was very gladly and ran with me to the washroom. After she washed her hand, I took her back to car. Still, her mom didn’t come. I really hoped the girl would tell her mom what had been happened to her. But next time the mom wouldn’t leave her little daughter in the car on herself.
