What do you think of a forest, what do you see? Just trees? Or do you see many other things, such as singing birds, colourful plants and wild flowers?
The forest is a whole world of its own. It is ______ many different living things. But even though they are all different, they have one thing in common: they all need each other in order to live on.
The trees feed the forest "people" by making food in their leaves; by using sunlight to join water and minerals from the soil and air. Their deep network of roots joins the soil together and prevents it from dying out, making it possible for living things to live in it.

We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and clerks to sell it to us. We need people to prepare our food and cook it and others to take our waste things away. Then, of course, we need doctors, nurses, government leaders, mail men, telephone operators, and many ______.
We need other human beings in another way. We need people for ______, to talk over our problems, or exchange ideas. Think how lonely and unhappy you would be if you lived all alone.

In the 1920s, scientists found a collection of bones near Beijing,China. They believed that the bones were human and that they were about 500,000 years old. They also believed the bones were important because they were form a little-known stage in the evolution of human beings.
The bones were kept in Beijing until 1941. Then because the Japanese army was advancing towards the city, the scientists decided to send the bones to the US for safety.
Dr Harry L.Shapiro, former Professor of Anthropology（人类学）at Columbia University, has been searching for them ever since. He believes they were stolen by the American army officer whose job was to take them to the US. He could be right.
After the war, a Chicago businessman offered $5,000 to anybody with information about the bones. A woman phoned him and told him she knew where the bones were. He arranged to meet her on the 102nd floor of the Empire State Building in New York. They met and she told him that her husband had come home from China with fossils（化石）of a prehistoric（of the time before recorded history）man. She showed him photographs of them. Then she walked away and was never heard from again.
A few years later, however, a Sydney businessman reported that he had the bones and that he had buried them in a forest in Tasmania. He offered to say where for a large sum of money. Then he, too, was never heard from again. Someone, somewhere, has the bones but nobody seems to know who or where.
