题文

Think about what you had for lunch: Was it a hamburger? A chicken sandwich? Barbecue? What about vegetables? Would it surpri 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 ri becau humankind has been releasing (排放) amounts of gas into the atmosphere. One of the greenhou gas 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 gas into the atmosphere. The process of making a hamburger ,for example, requires a lot of energy. A cow has to be fed and raid on farmland, and cow waste is a major source of methane (沼气) — an especially powerful greenhou gas. The cow has to be killed. The meat has to be procesd (加工) and shipped to a shop, which takes fuel . Most of the cow won’t even be ud 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 gas 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 greenhou gas relead. All kinds of meat are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, nds 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.小题1:The questions asked in the first paragraph are ud to _____.A．show the author’s concern about food safetyB．express the author’s puzzlement at what to eat C．remind readers of something delicious to eatD．introduce the topic to be discusd in the passage小题2:What is the bad news for meat-eaters?A．Meat producing can cau global warmingB．Most cows are raid not for people to eatC．There is a lot of carbon dioxide in meatD．Animals begin to die off becau of global warming小题3:Which is the most environment-friendly food according to the passage?A．BeefB．CarrotC．PorkD．Chicken小题4:The author wrote the passage in order to _____.A．explain the importance of eating meatB．advi people to keep a balanced dietC．encourage people to choo a greener dietD．introduce some healthy foods to people 题型：未知难度：其他题型
