导致 cause sth. result in lead to——青夏教育精英家教网—

　　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 have 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 storms.

　　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 311000 an“endangered nation”.

　　A new study suggests that very young children who watch a lot of television may have attention problems later in school．

　　Children with attention problems cannot sit still or control their actions．They talk too much, lose things, forget easily and are not able to finish tasks．

　　People with attention problems may suffer a condition known as Attention Deficit Disorder(A．D．D．)．Experts say the cause of A．D．D．involves chemicals in the brain．Teachers say many children in the United States are showing signs of disorder．Some education researchers have been saying for years that watching television at a very young age could change the normal development of the brain．For example, they say that children who watch a lot of television are not able to sit and read for an extended period of time．

　　The new study tested the idea that television watching by very young children is linked to attention problems by the age of seven．It involved more than 1300 children．There were two groups of children, ages one and three．Researchers at Children’s Hospital in Seattle, Washington reported the results in the publication Pediatrics(儿科)．They asked the parents how often the children watched television．The parents also described their children’s actions at the age of seven using a method that can tell if someone suffers Attention Deficit Disorder．

　　The children who watched a lot of television at an early age were most likely to have attention problems．Every hour of watching television increased the chances of having attention problems by about ten percent．

　　The researchers say that all the children with attention problems might not have A．D．D．But they still could face major learning problems in school．The findings support advice by a group of doctors that children under the age of two should not watch television．

　　One of the researchers says there are other reasons why children should not watch television．Earlier studies have linked it with children becoming too fat and too aggressive(好斗的)．Other experts say the new study is important, but more work needs to be done to confirm the findings and better explain the cause and effect．

　　本文描述的是儿童看电视对他们以后的一些消极的影响。孩子过早地看电视或者看电视过多都会导致孩子记忆力难以集中，多动，好斗，容易忘事等等。
