2. 同学，你知道中国的四大发明是什么吗？你知道蔡伦是怎样改进纸的吗？请你读一读下面的小短文，判断下面的句子是否正确，正确的写T(True)，错误的写F(False)。
When we think of paper, we think of newspapers, books, letters, envelopes(信封)and writing paper. So paper is important in our life.
Paper was first made in China. Before the invention of paper, people in China wrote on pieces of bones, bamboos or cloth. In the year 105, a man named Cai Lun began to experiment(实验). He used many things to make paper. He took bark(树皮), pieces of net and pieces of rags(破布). He broke these things down into very small pieces. He mixed all these things in a large container(容器)of water. Then he removed(去除)them. When he pressed out(挤压出)the water, he could see a thin sheet of paper.
The invention of paper was a great contribution(贡献)to human civilisation(文明).
