Driving into California's Sequoia National Park is like stepping back in time.The rugged forest is crowded with large fir trees and tall lodgepole pines,but they all look like puny twigs1 the giant sequoia.Sequoias fascinate people.They fascinate people by their size and age.They simply exceed human2. If it's true that size doesn't matter,then these giants still earn points for3.These trees can live up to three thousand years.The granddaddy of sequoias is General Sherman, a tree believed to be the largest single living thing on the planet.The General Sherman tree would4 three,full 12-foot wide lanes.It is 36 feet in diameter at the base.You can5it down.And the tallest sequoia tree is more than 100 yards long,more than the6of a full football field. And all giant sequoias will just keep on growing,and growing.It seems sequoias just get so big that the roots can't support them anymore.And then... what grows up... must 7. And when these trees falls in the forest,you can bet you'll hear it.The northwest settlers who discovered the sequoias in the 19th century were8 by what they saw. They had two9 . One was,wow, they're10. And the other was, wow,maybe we can make some money. For years early settlers tried to cut these giants down.But that proved to be a giant waste of time.When you tried to saw the wood11to break it apart,you discovered the wood is actually pretty12,which makes it virtually impossible to build13.
Sequoias survived the loggers, but they still have to brave the elements. Sequoias have a very special14to where they grow. They can live in snow obviously15they don't like below zero Fahrenheit weather. And sequoias also rely on another powerful element to16their survival.Giant sequoias are actually dependent on fire for their reproduction.The rising heat of a fire17a giant sequoia dries the cone and causes the scales to open.And the seeds are able to release.
In order to preserve these18wonders,the Sequoia National Park was created in 1890.By 1926,when the first roads were opened,crowds from around the world came19in.For being the largest and most20living organisms on the planet, the giant sequoia is rooted on our list at No. 9.

Among the devastating consequences of AIDS has 1 its epidemic spread in the developing world. The disease has caused 2 suffering, debilitation, loss of life and disruption of family, social and economic 3.

The search for an AIDS vaccine began more than 15 years ago with great 6 and high expectations. With the 7 of the human immunodeficiency virus (HIV) as the cause of AIDS, it seemed that a 8 would follow closely behind. But despite a large concerted effort, the problem has proven more difficult than 9, and progress has not 10 the 11 hopes. Here I review the 12 scientific obstacles confronting the development of an effective HIV vaccine, and I consider 13 strategies to overcome these obstacles.
It is instructive to consider the circumstances that have 14 to past successes in vaccine development. The smallpox vaccine is 15 the most successful inventions in the history of 16. Why, 200 years ago, without the benefit of modern biotechnology, did the smallpox vaccine succeed so readily while an AIDS vaccine 17 elusive? The answer lies in an experiment of nature that provided, to an astute observer, a clear direction for smallpox vaccine development. In this classic story of 18 discovery, Edward Jennet noticed that milk maids who had previously contracted cowpox were 19 to smallpox infection. This observation was the critical event leading to the finding that the cowpox virus cross-reacted immunologically with the smallpox virus and could 20 be used to protect against smallpox.
