Last year my sixth-grader daughter ,Elizabeth ,was forced to put up with science .Her education week after week ,contained mindless memorization of big words like “batholith” and “saprophyte” She learned by heart the achievements of famous scientists who did things like “improved nuclear fusion(核聚变)”-never mind that she hasn’t the least idea of what nuclear fusion means .Elizabeth did very well(she’s good at memorizing things ). And now she hates science .My eighth-grader son ,Ben ,also suffered from science education . Week after week he had to perform lab experiments with answers already known .Ben figured out how to guess the right answers ,so he got good grades .Now he hates science ,too.

Science can provide an exciting way to develop children’s curiosity .Science education should teach ways to ask questions and seek answers .But my children got the mistaken idea in school than science is difficult dull and has no relation to their everyday interests .

As a physicist ,I am saddened and angered to see “the great science turnoff” I know that science is important in our lives .Yet studies prove that our schools are turning out millions of graduates who know almost nothing about and have almost no interest in science .What’s gone wrong ?Who is to blame ?

You might think that “global warming” means nothing more than a rise in the world’s temperature But rising sea levels caused by it have resulted in the first evacuation(撤离)of an island nation-the citizens of Tuvalu will have to leave their homeland.

During the 20th century ,sea level rose 8-12 inches. As a result .Tuvalu has experienced lowland flooding of salt water which has polluted the country’s drinking water.

Paani Laupepa , a Tuvaluan government official ,reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years .Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging torms.

Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions(导致温室效应的气体排放),which are a main cause of global warming . “By refusing to sign the agreement ,the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.

Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries .

Tuvalu is not the only country that is vulnerable(易受影响的)to rising sea levels .Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”.
