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 storms. Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an iuternationa] 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". The text is mainly about ______. A．rapid changes in earth's temperature B．bad effects of global warming C．moving of a country to a new place D．reasons for lowland flooding

The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, end their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark, on the other hand, was raised in the home of rich parents who had been to college. He was read to as a child, sent to a good school, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Peter's score was 85, well below the level he might have attained if reared under average conditions. Mark' s score was 125, twenty-five points above the average and fully forty points higher than his identical brother. Given equal opportunities, the twins would have tested at roughly the same level. (38) A．Children reared under average conditions possess average intelligence. B．Lack of opportunity prevents the growth of intelligence. C．An individual's intelligence is determined chiefly by his environment. D．Changes of environment produce changes in the brain structure.

That is because the tidiness lobby counts the benefits of neatness, but not its costs. A rough storage system (important papers close to the keyboard, the rest distributed in loosely related piles on every flat surface) takes very little time to manage. Filing every bit of paper in a precise category, with colour-coded index tabs and a neat system of cross-referencing, will certainly take longer. And by the end, it may not save any time. Your reviewer's office is easily the most untidy in The Economist (not entirely his own work, it should be said, thanks to the heroic efforts of his even untidier office-mate). But when it comes to managing information, there seems to be no discernible difference in the end result. The authors of this book trawl the furthest reaches of psychology, management studies, biology and physics to show why a bit of disorder is good for you. Chiefly, it creates much more room for coincidence and serendipity. Alexander Fleming discovered penicillin because he was notoriously untidy, and didn't clean a Petri dish, thus allowing fungal spores to get to work on bacteria. He remarked wryly on visiting a colleague's spotless lab: "no danger of mould here". It can also help make sense of things. Hearing depends on random movement of molecules: when they coincide with sounds from outside, they are strong enough to stimulate the inner ear. A bit of background noise on the phone enables our ears to filter out echoes. A slightly mushy photograph can be easier to understand. Music and art depend on mess. Procrastination makes sense too. America’s Marine Corps, the authors repeat (several times), never makes detailed plans in advance. Leaving important things to the last minute reduces the risk of wasting time on things that may ultimately prove not important at all. The authors are witheringly contemptuous of the bogus equation of tidiness and morality—for example in corporate "clean desk" policies. Disorder and creativity are so closely linked that any employer who penalizes the first sacrifices the second, they argue. America's professional organizers, a thriving and lucrative cult of tidiness coaches, are merchants of guilt, not productivity boosters. It's all fine, up to a point. But the book has two weaknesses. One is that it overstates the case. The case for tidiness in some environments—surgery, a dinner table or income tax returns—is really overwhelming. The other is that the book is a bit repetitive and disorganized. Even readers who love mess in their own lives don't necessarily like it in others. Paraphrase the sentence "the tidiness lobby counts the benefits of neatness, but not its costs". (para. 2)

The first study was done at Duke University in Durham, North Carolina. Researchers pumped extra carbon dioxide into a test area where pine trees were growing. The trees grew thirty-four percent faster during the first three years. However, in time, the trees slowed to about their normal growth rate. The scientists say this is because trees need other nutrients, such as nitrogen. In the second study, researchers from Duke and Bowdoin College in Brunswick, Maine examined the soil around trees. They discovered that as the leaves broke down into the soil, all the carbon was not trapped in the soil. Much of it was released into the atmosphere as carbon dioxide. The findings of the two studies were published last month in Nature magazine. They suggest there is limited value in planting trees to reduce the carbon dioxide pollution in the atmosphere. Forest planting has been a part of negotiations on a world agreement to reduce greenhouse gases that scientists believe cause global warming. The United States, Canada, Japan and some other industrial countries have supported the idea. But this new research suggests the idea is not as effective as environmental activists had thought. Scientist Ram Oren of Duke University led the study on tree growth. He says that earlier estimates on the ability of forests to absorb carbon dioxide were overly hopeful. Some scientists not involved in the studies say the research provides some of the first evidence on how trees react to carbon dioxide. Other scientists say the research disputes a belief among some coal and power companies. The companies say that rising levels of carbon dioxide in the atmosphere will not create harmful global warming. Instead, they say it will increase forests and other plants. What is the purpose of this passage？ A．Introduce some new ideas about the relationship between trees and carbon dioxide. B．Introduce recent condition of global industrial pollution. C．Call on people to plant more trees to reduce greenhouse gases. D．Point out that power companies should be responsible for the rising levels of carbon dioxide.
