Unit 4 Wildlife protection Period 1 Warming Up & Reading课时巩固提升Life is good for penguins in Antarctica(南极洲)at the end of the movie Happy Feet. Real-life penguins, though, have little to celebrate. Twelve of the worlds nineteen penguin species(种类)face serious danger, according to wildlife experts. They are in danger of disappearing from the earth, including emperor penguins. “Many of the worlds penguin species are in big trouble, ”penguin expert Kassel Siegel told WR News. Her wildlife group is asking the US government to protect the twelve species of penguins in danger. Several countries are making efforts to make sure the rapidly increasing tourists in Antarctica do not cause environmental problems. Overfishing is one reason for the problem. Penguins eat small fish and tiny animals called krill. Fishing boats are catching lots of krill. That leaves less food for penguins to eat. Another reason for the decline(减少)in the number of penguins is global warming. Global warming is the slow increase in average temperature around the world. It is causing sea ice to melt. Penguins need the sea ice as a place to rest while they search for krill. Scientists say global warming is caused when we drive cars or use electricity. That burns coal, and natural gas. The burning of coal, oil, and natural gas gives off gases that add to the overheating of the earth. “We can and must reduce gas emission(排放物)to keep penguins safe in the future, ”says Siegel. 【语篇概述】本文主要讲述了企鹅面临灭绝的危险以及造成这种状况的原因。.
