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 dioxide. 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 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
B. express the author’s puzzlement at what to eat
C. introduce the topic to be discussed in the passage
D. remind readers of something delicious to eat

A. Most cows are raised not for people to eat.
B. Meat producing contributes to global warming.
C. There is a lot of carbon dioxide in the meat we eat.
D. Animals begin to die off because of global warming.

Think about what you usually have for a meal: Is it a hamburger? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet?
It can--in a big way. Scientists attending the American Association for the Advancement of Science meeting in Chicago presented new studies showing how food and its production affect the globe and its warming climate. It is generally believed that global warming is caused by the large amounts of greenhouse gases released into the atmosphere. One of these greenhouse gases is carbon dioxide.
What does this have to do with food? A big part of the carbon dioxide comes from the process of making and eating food, the scientists reported in Chicago. The production of meat contributes to a lot of that carbon dioxide.
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 manure(肥料)is a major source of methane(甲烷)--an especially powerful greenhouse gas. By the time a hamburger is finally served on a dinner plate, it has done great harm to the environment.
The message from the research is clear: We can greatly reduce the production of greenhouse gases by eating less meat.
All kinds of meat, the scientists reported, 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 or other greenhouse gases into the air. So shifting our diet to less meat and more vegetables ,as it turns out, may do the world some good.
1.Generally speaking , people believe that global warming is caused by ________.
A. cutting down too many trees.
B. releasing too many greenhouse gases.
C. growing too many vegetables.
D. raising too many cows.
2.Which of the following is NOT true?
A. To make and eat meat requires a great deal of energy.
B. To feed and raise cows on farmland contributes to greenhouse gases.
C. To make and eat hamburgers sends greenhouse gases into the air.
D. To grow and eat vegetables does no harm to the environment.
3.According to the passage , the writer seemingly intends to ________.
A. appeal to us to protect the environment by eating less meat food.
B. persuade us to develop a good eating habit to keep healthy
C. advise us to make less hamburgers in order to save energy.
D. encourage us to grow more vegetables to reduce greenhouse gases.

Think for a moment about the teachers you’ve had at junior or senior high school. Which one did you like best? And why? Were the teachers you liked best also the ones who were the best teachers, in your opinion? 1.And then begin to read further.
Some very common answers to this question are that teachers need to love their students, that they need to have expert knowledge of their subjects and that they should devote themselves completely to their work. All of these ideas are, of course, true to a certain extent.2.
It’s impossible for anyone to love everyone he knows, and teachers deal with a very large number of students over the years. On the other hand, teachers should certainly be able to make their students feel that they’re interested in them as people. 3. A deep knowledge of the subject is especially important.4. That’s to say, a teacher needs to be trained in the skills of teaching. These skills include how to control a class. Finally, teachers have to devote a lot of time and energy to their work, of course. However, because they’re also models that their students must follow, it’s important that they should be well-balanced people with interests outside their school work—families, friends, hobbies, etc. 5.
A.They’re perhaps a little too simple.
B.Students ask too much from teachers.
C.Well- qualified teachers should be educated and capable.
D.Consider for a minute the qualities that make a teacher outstanding.
E.A teacher who only lives for work is likely to become narrow-minded.
F.Equally important is the ability to pass that knowledge on to the students effectively.
G.They also pay attention to the development of both their brains and their characters.
