③损害开始为一针头至黄豆大的蜡样结节,逐渐增大并形成溃疡,溃疡逐渐向四周扩大,边缘呈珍珠样隆起伴有毛细血管扩张,表面有棕色结痂,去痂后易出血,严重者可破坏皮下组织及骨骼。

Many people could not forget the beautiful dance during the CCTV Spring Festival Gala. The dance was performed by 20 disabled girls. They can’t hear or speak. But their performance is remembered by many people. The leading dancer of the dance is Tai Lihua. She is 28 years old. She is very beautiful.

Tai Lihua was born healthy. When she was two years old, she lost her hearing because of a fever. Not long after that, she became mute(哑巴), too. From then on, her world was silent. But she didn’t know this at first. At five years old, when she played a game about sounds with her schoolmates she discovered that she was different from the others. She was very sad about it. Her father went to many places to look for best treatments for her illness. But nothing worked. When she was seven years old, she went to a school for deaf and mute children. In that school, she did well in her studies. Her teacher said she used her mind more than the others and was good at expressing her feeling through dance. She also began to love dance. She thought she could use dance to express what she thought about life.

When she was 15 years old, she began to learn to dance. At first, she couldn’t dance well. But she didn’t stop. She worked harder than the others. She also spent more time learning. Her efforts made her a very good dancer. She has been to many countries to perform and many foreigners like her style. She now lives a happy life with her family.
