高中英语人教版选修六Unit 4 Global warming同步练习 (3)
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 that 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 (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 book ABigFatCrisis: TheHiddenForcesBehindObesityEpidemic— andHowWeCanEndIt by Deborah Cohen, a senior natural scientist, is very popular now. {#blank#}1{#/blank#} But according to this book, the following are some misunderstandings of obesity or being overweight.
1).If you're obese, blame your genes.
{#blank#}2{#/blank#} Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible. At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.
2).If you're obese, you lack selfcontrol.
Research shows that if we are faced with too much information, we have a tendency to make poor choices on diet. {#blank#}3{#/blank#} Even, the most vigilant(警觉的)people may not be good controllers of themselves.
3).{#blank#}4{#/blank#}
Although the US Department of Agriculture estimates that fewer than 5 per cent of Americans live in the “food deserts”, about 65 per cent of the nation's population is obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.
4).The problem is not that we eat too much, but that we don't exercise.
Michelle Obama's “Let's Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. {#blank#}5{#/blank#} In fact, although a drop in workrelated physical activity may explain up to 100 fewer calories burned, leisure physical activity appears to have increased.
A.Lack of access to fresh fruits and vegetables is a cause of obesity. B.Obesity rates have increased. C.Fresh fruits and vegetables we choose in a supermarket are related to obesity. D.But there was no obvious decrease in physical activity levels as obesity rates climbed in the 1980s and 1990s. E.People hold different views on obesity. F.People benefit a lot from physical activities. G.Our world has become so rich in food that we can be led to consume too much in ways we can't understand. |
