is the adder. In Scotland, in fact, there are no other snakes at all. The adder
is also the only British snake with a poisonous bite. It can be found almost
anywhere, but prefers’ sunny hillsides and rough open country, including high
ground. In Ireland there are no snakes at all. Most people regard snake bites as fatal misfortune, but net all bites are serious, and very few are fatal. Sometimes attempts at emergency treatment turn out to be dangerous than the bite itself, with amateurs heroically, but mistakenly, trying do-it-yourself surgery and other unnecessary measures. All snakes have small teeth, so it follows that all snakes can bite, but only the bite of the adder presents any danger.

Gases in the Earth’’s atmosphere act like glass in a greenhouse-trapping heat and making life on Earth possible. But there is a delicate balance. Burning coal, oil and natural gas increases atmospheric concentrations of these gases. Over the past century, increases in industry, transportation, and electricity production have increased gas concentrations in the atmosphere faster than natural processes can remove them leading to human-caused warming of the globe.
The Sources Of Global Warming

[单项选择]Researchers who picked up and analyzed wild chimp droppings said on Thursday they had shown how the AIDS virus originated in wild apes in Cameroon and then spread in humans across Africa and eventually the world. Their study, published in the journal Science, supports other studies that suggest people somehow caught the deadly human immunodeficiency virus (HIV) from chimpanzees, perhaps by killing and eating them.
"It says that the chimpanzee group that gave rise to HIV... this chimp community resides in Cameroon," said Beatrice Hahn of the University of Alabama, who led the study. "But that doesn’t mean the epidemic originated there because it didn’t," Hahn, who has been studying the genetic origin of HIV for years, said in a telephone interview. "We actually know where the epidemic took off. The epidemic took off in Kinshasa, in Brazzaville." Kinshasa is in the Democratic Republic Congo, formerly Zaire, and faces Brazzaville, in Congo, across the Congo River. Studies have A. monkeys are also susceptible to HIV. B.
