作文地带提供中文材料：

李涛是我校年轻的老教师。他被看作是老教师，是因为他教化学已经有20年了。说她年轻，因为他今年还不过38岁。他长得比较瘦。头上头发不多，灰白了。他常带着深度眼镜，牙齿又缺了两颗。

所以他看上去比他实际年龄要大。他说，在公共汽车上常常有人给他让座。

事实上。我曾看见他不止一次地给怀抱婴儿的妇女让过座。只要听一听他的化学课——那棵又生动又有趣，你就会发现他真正的年龄。

Li Tao is a young superior teacher of our school.He is superior,because he has been teaching chemistry for 20 years.He is young becasu he is less than 38 years old new.He is a thin man with few hairs and most of which is grey.

He always wear a pair of glasses with high degree.And he lost two of his teeth,so he seems older than he really is.He said it is very often that people give him their seat on bus.

But acctually I have seen him more than once giving his seat to women with children.

Only if you listen to his chemistry class which is vivid and interesting,you will find out his real age.
