Some kinds of bamboo can grow one metre in a day. That is why bamboo is one of the fastest-growing plants on the earth. In some places in China, people can almost watch it grow. Bamboo is also one of the most useful plants. People use it to make houses, chairs, baskets and even paper. In the past, Chinese people wrote on bamboo before paper was invented. Young bamboo shoots can be eaten, too. They are a popular food in spring. Bamboo is very strong, but it is not a tree. It is a kind of grass. When the wind blows, bamboo bends but does not break. That is why many Chinese people say bamboo is like a good person — strong, useful and never afraid. Today pandas are in danger, and bamboo forests are becoming smaller. We must protect the bamboo forests, because they are the home of the panda. 1．How fast can some kinds of bamboo grow? 2．What do people use bamboo to make? 3．What did Chinese people write on before paper was invented? 4．Is bamboo a tree? 5．Why must we protect the bamboo forests?
