When Albert Einstein was young, he was a quiet child who spent much of his time alone. He was slow to talk and had difficulty in learning to read.
When Albert was five years old, his father gave him a compass. Albert was filled with wonder when he discovered that the compass needle always pointed in the same direction ---- the north. He asked his father and his uncle what caused the needle to move. Their answers were difficult for Albert to understand. Yet he spent a lot of time thinking about them. He said later that he felt something must be hidden behind things.
Albert didn’t like school. The German schools of that time were not pleasant. Students couldn’t ask questions. Albert said he felt as if he were in prison..
One day Albert told his uncle Jacob how much he hated school, especially mathematics. His uncle told him to solve mathematical problems by pretending to be a policeman. “You are looking for someone,” he said, “but you don’t know who he is. Call him X. Find him by using your mathematical tools.”
Albert learned to love mathematics. He was studying the complex mathematics of calculus while all his friends were still studying simple mathematics. Instead of playing with his friends he thought about things such as “What would happen if people could travel at the speed of his light?”
Albert wanted to teach mathematics and physics. He graduated with honors, but it was a pity that he could not get a teaching job.

Edward Wilson is America’s, if not the world’s, leading naturalist. In The Future of Life, he takes us on a tour of the world’s natural resources(资源). How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity(生物多样性)of our earth.
Wilson begins with an open letter to the pioneer in environment (环境) protection, Henry David Thoreau. He compares today’s Walden Pond with that of Thoreau’s day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Can the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future?
Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species(物种) are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas.
At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas in this book.

|
A．the environment for plants |

2. How many species are most important to our present food supply?
|
A．Twenty. |

|
A．learn how to farm scientifically |
