Several interesting American museums tell about health subjects. One is the Doctor Samuel D. Harris National Museum of Dentistry. It is at the University of Maryland in Baltimore. That is where the first college in the world to train dentists began. The museum tells about the history of the medical treatment of teeth. Visitors can see some frightening devices that once were used to remove infected (受感染的) teeth. They also can see sets of teeth made of animal bone. They were made for a famous American -- the first President, George Washington.

Most people do not consider a visit to the dentist their idea of a good time. However, the director of the museum says he wanted to make the museum a fun place to visit. He says he also wants to teach visitors about the importance of taking care of their teeth.

Another museum collects devices that help people hear. The Kenneth W. Berger Hearing Aid Museum is at Kent State University in Kent, Ohio. The museum has more than three-thousand hearing aids from around the world. They include old and strange devices. Some hearing aids were made to look like other objects. That is because in the past many people did not want anyone to know they were wearing a hearing aid.

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.

If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants.

Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit.

Most non-flowering plants do not grow from seeds. They grow from spores(胚芽). Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.

One day about 30 years ago, a 2 year-old Chinese boy in Shenyang was watching a Tom and Jerry cartoon on TV. Tom the cat began to play the piano. The music was to beautiful that the boy fell in love with it at once. This little boy was Lang Lang – one of today’s great pianists.

Lang Lang began to play the piano at 3. By the age of 5, the had won fist place in Shenyang’s piano competition and performed his first public recital(独奏会). People were shocked by his perfect performance and thought he was a real talent. From that time on, playing on the global stage became the dream of Lang and his parents.

To help him much closer to his dream, when Lang was 9, his father quit his job and went with Lang to Beijing to help his son study piano. There, Lang did not receive the praise that he had received at home, and he experienced the hardest time of his life.

“I was kicked out of the class by my piano teacher six months later. It totally destroyed my piano dream,” Lang said in an interview on a Chinese TV program. Hearing about his son’s failure, Lang’s father was so furious(暴怒的) and frustrated(沮丧的) that he told Lang either to go back to Shenyang, or to commit suicide( 自杀). Feeling hopeless and in pain, Lang tried to damage his fingers by crushing(砸) them against a wall. He hated piano!
