One of the most widely accepted, commonly repeated assumptions (假设) in our culture is that if you exercise, you will lose weight. I exercise all the time, but I still have gut fat that hangs over my belt when I sit. Why isn’t all the exercise getting rid of it?
It’s a question many of us could ask. More than 45 million Americans now belong to a health club, up from 23 million in 1993. We spend some $19 billion a year on gym memberships. Of course, some people join and never go. Still, as one major study — the Minnesota Heart Survey — found, more of us at least say we exercise regularly.
And yet obesity (肥胖) figures have risen sharply in the same period: a third of Americans are obese, and another third count as overweight by the Federal Government’s definition. Yes, it’s entirely possible that those of us who regularly go to the gym would weigh even more if we exercised less. But like many other people, I get hungry after I exercise, so I often eat more on the days I work out than on the days I don’t. Could exercise actually be keeping me from losing weight?
The popular belief that exercise is essential for weight control is actually fairly new. As recently as the 1960s, doctors routinely advised against too much exercise, particularly for older adults who could injure themselves. Today doctors encourage even their oldest patients to exercise, which is sound advice for many reasons: People who regularly exercise are at significantly lower risk for all manner of diseases — those of the heart in particular. They less often develop cancer and many other illnesses. But the past few years of obesity research show that the role of exercise in weight loss has been wildly over-evaluated.
“In general, for weight loss, exercise is pretty useless,” says Eric Ravussin, exercise researcher at Louisiana State University. Many recent studies have found that exercise isn’t as important in helping people lose weight as you hear so regularly in gym advertisements or on shows like The Biggest Loser — or, for that matter, from magazines like this one.
The basic problem is that while it’s true that exercise burns calories and that you must burn calories to lose weight, exercise has another effect: it can make one hungry. That causes us to eat more, which in turn can negate (使无效) the weight-loss benefits we just gained. Exercise, in other words, isn’t necessarily helping us lose weight. It may even be making it harder.

Homemade Ice Cream in a Bag
Difficulty: Very Easy
Average User Rating:★★★★☆(4.3/5)
Milk can become homemade ice cream in five minutes by using a bag! This homemade, creamy treat is a summertime delight for your kids and you alike.
What you’ll need:
1 tablespoon of sugar; 1/2 cup of milk; 1/4 teaspoon of vanilla (香草香精); 6 tablespoons of rock salt; 1 small-sized plastic food storage bag; 1 gallon-sized plastic food storage bag; ice cubes.
How to make it:
l Fill the large bag half full of ice, and add the rock salt. Seal the bag.
l Put milk, vanilla, and sugar into the small bag, and seal it.
l Place the small bag inside the large one, and seal it again carefully.
l Shake until the mixture turns into ice cream, which takes about five minutes.
l Wipe the top of the small bag, and then open it carefully. Enjoy!
Tips:
1/2 cup of milk will make about one spoon of ice cream, so double the recipe if you want more. But don’t increase the amount more than that—a large amount might be too big for kids to pick up because the ice itself is heavy.
Here is another version of the homemade ice cream recipe from another parent!
These are the homemade ice cream ingredients:
1/4 teaspoon of vanilla butter and nuts; 1 tablespoon of sugar; 1/2 cup of milk.
These are the other supplies:
Plastic sandwich bag; 12 salt pellets; 1 dish of ice; large plastic bag.
Put the ice cream ingredients in the small bag, and then put the bag, salt and ice in the big bag. Hold the bag shut and move it around on the floor for about 5 minutes.
When I made ice cream at home last time, although the salt pellets didn’t really dissolve (溶解) that well, I still got ice cream. It was not smooth ice cream, probably because of the low-fat milk. It was incredible that it could be ready in 5 minutes (not counting preparing the ingredients)
Next, I changed the recipe, using a tablespoon of cocoa, a tablespoon of sugar, and a cup of milk. It was a bit too chocolaty, but good!
【小题1】The underlined “that” in “Tips” section refers to ____.

Paragraph 1
Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day. They are: (1) green and yellow vegetables of all kinds. (2) citrus(柑桔) fruits and tomatoes; (3) potatoes and other fruits and vegetables; (4) meat of all kinds, fish and eggs; (5) milk and foods made from milk; (6) bread or cereal(谷类), rice is also in this kind of food; (7) butter, or something like butter.
Paragraph 2
People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether foods are eaten raw(生的) or cooked, canned or frozen. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is what you eat every day.
Paragraph 3
There are two problems, then, in feeding the large number of people on earth. The first is to find some ways to feed the world’s population so that no one is hungry.
The second is to make sure that people everywhere have the right kinds of food to make them grow to be strong and healthy.
