    Think about what you had for lunch: Was it a hamburger? A chicken sandwich? Barbecue? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet?

    It can—in a big way. New studies show how food and its production affect the globe and its warming climate. You’ve probably heard of global warming : The temperature is on the rise because humankind has been releasing (排放) amounts of gases into the atmosphere. One of these greenhouse gases is carbon dioxide（二氧化碳）.

    What does this have to do with food ? A big part of the carbon dioxide that we put in the atmosphere every year comes from the process of making and eating food. The production of meat contributes a lot of that carbon diode. And much of meat’s contribution comes from beef , which is responsible for releasing even more warming gases into the atmosphere.

    The process of making a hamburger ,for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow waste is a major source of methane (沼气) — an especially powerful greenhouse gas. The cow has to be killed. The meat has to be processed (加工) and shipped to a shop, which takes fuel . Most of the cow won’t even be used for meat that people eat. By the time a hamburger finally lands on a dinner plate, it has made a heavy effect on the environment.

    We can reduce the production of global-warming gases by eating less beef .Other kinds of meat like pork and chicken do less harm to the environment—at least in terms of the amount of greenhouse gases released. 

    All kinds of meat are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide into the air. So changing our diet to less meat and more vegetables, as it turns out, may do the world some good.

    1.The questions asked in the first paragraph are used to _____.

    A．show the author’s concern about food safety

    A．Beef

    B．Carrot

    A

       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 have 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 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 311,000 an “endangered nation”.

    56. The text is mainly abou_________ .

           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

    57. According to scientists, the DIRECT cause of more and fiercer storms is________.

           A. greenhouse gas emissions in industrialized nations

    B. higher surface water temperatures of the sea

    C. continuous global warming

    D. rising sea levels

    58. Laupepa was not satisfied with the United States because it did not_______.

    A. agree to reduce its greenhouse gas emissions

    B. sign an agreement with Tuvalu

    C. allow Tuvaluans to move to the US

    D. believe the problems facing Tuvalu were real
