the traits found within the seeds：the genes that give one variety resistance to a particular pest and another variety tolerance for hot，dry weather.

　　　Few people will ever see or come into contact with the contents of this vault. In sealed boxes，behind multiple locked doors，monitored by electronic security systems, enveloped in below-zero temperatures, and surrounded by tons of rock, hundreds of millions of seeds are protected in their mountain fortress. Frozen in such conditions inside the mountain, seeds of most major crops will remain viable for hundreds of years, or longer. Seeds of some are capable of retaining （保留） their ability to grow for thousands of years.

　　　Everyone can look back now and say that the Seed Vault was a good and obvious idea, and that of course the Norwegian government should have approved and funded it. But back in 2004, when the Seed Vault was proposed, it was viewed as a crazy，impractical, and expensive idea.

　　　We knew that nothing would provide a definite guarantee. But we were tired，fed up，and frankly scared of the steady, greater losses of crop diversity. The Seed Vault was built by optimists who wanted to do something to preserve options so that humanity and its crops might be better prepared for change. If it simply resupplied seed gene banks with samples those gene banks had lost, this would repay our efforts.

　　　The Seed Vault is about hope and commitrnent - about what can be done if countries come together and work cooperatively to accomplish something significant，long-lasting，and worthy of who we are and wish to be.
