Food can be divided into two basic categories: real food and pleasure food, Real food is fuel for the body's needs, while pleasure food, which is high in fat and/or sugar, is primarily for taste satisfaction. The categories are pretty obvious. Broccoli is real food. Cookies are in the pleasure group.
When you're hungry, you are faced with choices. If you're not suffering from excessive hunger, you can be rational about them. Go to the refrigerator. What looks good？ If you have chosen a real food, say, a turkey sandwich, you can be certain your body can use it for fuel. Eat it and enjoy.
Two hours later you are hungry again. Back to the refrigerator. What looks good？ Ice-cream. Stop! Employ your willpower just a little. Ice-cream isn't what your body needs. Does something else look good？ Yes, a piece of toast with peanut butter and a glass of milk sound good too. Okay, go ahead--remembering that high-fat real foods should be eaten in moderation.
One trick is to eliminate pleasure foods from your kitchen. Instead, keep a variety of high quality foods available at all times. In short, buy lots of delicious real food-food you really like-and get rid of the junk.
But what if you have ice-cream on hand and nothing else sounds good？ Although you don't want to eat pleasure foods whenever the urge strikes, there is a legitimate (合情合理的) place for them in your diet. If you have analyzed your feelings and there are no other needs imitating hunger, eat the ice-cream. You have not failed. On the contrary, you have accepted your natural appetite, but not blindly.
Surprisingly, when you know you can eat anything you want, and that you never have to put up with unsatisfied hunger again, it takes a lot of pressure off. You'll begin to want to eat what your body needs, and your body will begin to need foods that will lead to slimness.
Which of the following statements is Not true？
Carl Sandburg and a lot of others have tried to make something out of Lincoln that he wasn't. He was a decent man, a good politician, and a great President, and they've tried to build up things that he never even thought about. I'll bet a dollar and a half that if you read Sandburg's biography of Lincoln, you'll find things put into Lincoln's mouth and mind that never even occurred to him. He was a good man who was in the place where he ought to have been at the time important events were taking place, but when they write about him as though he belongs in the pantheon (从神庙) of the gods, that's not the man he really was. He was the best kind of ordinary man, and when I say that he was an ordinary man, I mean that as high praise, not deprecation. That's the highest praise you can give a man. He's one of the people and becomes distinguished in the service that he gives other people. He was one of the people, and he wanted to stay that way. And he was that way until the day he died. One of the reasons he was assassinated was because he didn't feel important enough to have the proper guards around him at Ford's Theatre.
According to the passage, Lincoln was ______ .
听力原文： Recent research has claimed that an excess of positive ions in the air can have an ill-effect on people's physical or psychological health. What are positive ions？ Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charges. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorms, earthquakes or when winds are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing made of man-made fibers, or from TV sets, duplicators or computer display screens.
When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some particularly sensitive people suffer nausea or even mental disturbance. Animals are also found to be affected, particularly before earthquakes; snakes have been observed to come out of hibernation, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California.
Conversely, when large numbers of negative ions are present, people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with tumbling streams or waterfalls.
