第三篇
Americans still have been gaining weight,although they have cut their average fat intake from 36 to 34 percent of their total diets in the past 15 years.Indeed,cutting fat to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates（碳水化合物）which break down into amino acids and simple sugars respectively,have just four. Moreover,the body uses fewer calories to metabolize（新陈代谢）fat than it does to metabolize other foods.
But cutting fat from your diet doesn't necessarily mean your body won't store fat. For example, between nonfat and regular cookies,there's trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers,soups and dressings can also be just as high in calories as richer versions.No matter where the calories come from,overeating will still cause weight gain.The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand.He wasn't losing weight.Then he showed his food diary to his coach and revealed he'd been eating half a pound of jelly beans a day."They don't have any fat,"he explains.But they had enough sugar to keep him from losing an ounce.
Nonfat foods become add-on foods.When we add them to our diet,we actually increase the number of calories we eat per day and gain weight. That was born out in a Pennsylvania State University study.For breakfast,Prof. Barbara Rolls gave two groups of women yogurt that contained exactly the same amount of calories.One group's yogurt label said"high fat”一the other,"low fat". The"low fat"yogurt group ate significantly more calories later in the day than the other group. "People think they've saved fat and can indulge themselves later in the day with no adverse consequences,"says Richard Mattes,a nutrition researcher at Purdue University."But when they do that,they don't compensate very precisely,and they often end up overdoing it."
What can be inferred from the passage?
A.To avoid being overweight,people should eat nonfat food.
B.Nonfat and regular food have no difference in calories.
C.Americans think it necessary to count calories of food.
D.We can eat nonfat food as much as we like.

[单项选择]That experiences influence subsequent behavior is evidence
of an obvious but nevertheless remarkable activity called remembering. Learning
could not occur without the function popularly named memory. Constant practice
has such an effect on memory as to lead to skilful performance on the piano, to
recitation of a poem, and even to reading and understanding these words.
So-called intelligent behavior demands memory, remembering being a primary
requirement for reasoning. The ability to solve any problem or even to recognize
that a problem exists depends on memory. Typically, the decision to cross a
street is based on remembering many earlier experiences.
Practice (or review) tends to build and maintain memory for a task or for any
learned material. Over a period of no practice what has been learned tends to be
forgotten; and the adaptive consequences may not seem obvious. Yet, dramatic
instances of sudden forgetting can be seen to be adaptive. In this sense, the
ability to forget can be interpreted to have survived through a process of
natural selection in animals. Indeed, when one’s memory of an emotionally
painful experience leads to serious anxiety, forgetting may produce relief.
Nevertheless, an evolutionary interpretation might make it difficult to
understand how the commonly gradual process of forgetting survived natural
selection.
In thinking about the evolution of memory together
with all its possible aspects, it is helpful to consider what would happen if
memories failed to fade. Forgetting clearly aids orientation in time, since old
memories weaken and the new tend to stand out, providing clues for inferring
duration. Without forgetting, adaptive ability would suffer, for example,
learned behavior that might have been correct a decade ago may no longer be.
Cases are recorded of people who (by ordinary standards) forgot so little that
their everyday activities were full of confusion. This forgetting seems to serve
that survival of the individual and the species.
Another line
of thought assumes a memory storage system of limited capacity that provides
adaptive flexibility specifically through forgetting. In this view, continual
adjustments are made between learning or memory storage (input) and forgetting
(output). Indeed, there is evidence that the rate at which individuals forget is
directly related to how much they have learned. Such data offers gross support
of contemporary models of memory that assume an in-put-output balance.The tone of the passage can best be described as ______.
A. humorous
B. theoretical
C. exaggerative
D. philosophical
[单项选择]No one doubts ______ he is the best leader in the company.
