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 world's 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 world's 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。 Ⅰ.
