Reading task 1.
The oldest living things on Earth are trees. Some of California's sequoias have for four thousand years looked down on the changes in the landscape and the comings and goings of humans. They sprouted from tiny seeds about the time the Egyptian pyramids were being built. Today these giant patriarchs seem as remote and inaccessible as the rocks and mountain cliffs, on which they grow, like cathedral columns holding up the sky. It is hard to imagine them playing any part in the lives of mere humans or being in any way affected by the creatures that pass at their feet.
Lesser trees, however, have played an intimate role in the lives of people since they first appeared on Earth. Trees fed the fires that warmed humans: they provided shelter, food and medicine and even clothing. They also shaped people's spiritual horizons. Trees expressed the grandeur and mystery of life, as they moved through the cycle of seasons, from life to death and back to life again. Trees were the largest living things around humans and they knew that some trees had been standing on the same spot in their parent's and grandparents' time, and would continue to stand long after they were gone. No wonder these trees became symbols of strength, fruitfulness, and everlasting life.
