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.

Think about the last time you felt a negative emotion—like stress, anger, or frustration. What was going through your mind as you were going through that negativity? Was your mind cluttered with (充斥) different kinds of thoughts? Or was it paralyzed, unable to think?
The next time you find yourself in the middle of a very stressful time, or you feel angry or frustrated, stop. Yes, that’s right, stop. Whatever you’re doing, stop and sit for one minute. While you’re sitting there, completely immerse yourself in the negative emotion.
Allow that emotion to consume you. Allow yourself one minute to truly feel that emotion. Don’t cheat yourself here. Take the entire minute—but only one minute—to do nothing else but feel that emotion.
When the minute is over, ask yourself, “Am I willing to keep holding on to this negative emotion as I go through the rest of the day?”
Once you’ve allowed yourself to be totally immersed in the emotion and really feel it, you will be surprised to find that the emotion clears rather quickly.
If you feel you need to hold on to the emotion for a little longer, that is OK. Allow yourself another minute to feel the emotion.
When you feel you’ve had enough of the emotion, ask yourself if you’re willing to carry that negativity with you for the rest of the day. If not, take a deep breath. As you exhale, release all that negativity with your breath.
This exercise seems simple—almost too simple. But, it is very effective. By allowing that negative emotion the space to be truly felt, you are dealing with the emotion rather than stuffing it down and trying not to feel it. You are actually taking away the power of the emotion by giving it the space and attention it needs. When you immerse yourself in the emotion, and realize that it is only emotion, it loses its control. You can clear your head and proceed with your task.

Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills(风车) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind(碾碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher cost. Today, there is a global movement to supply more and more of our electricity through the use of wind.
1.From the text we know that windmills________.
A. were invented by European armies
B. have a history of more than 2,800 years
C. used to supply power to radio in remote areas

2.What was a new use for wind power in the late 19th century?
A. Sailing a boat.

3.One of the reasons wind was rediscovered in the 1970s is that_______.
A. wind power is cleaner
B. it is one of the oldest power sources.
C. it was cheaper to create energy from wind

4.What would the author probably discuss in the paragraph that follows?
A. The advantages of wind power.
B. The design of wind power plants.
C. The worldwide movement to save energy.
