Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable
diet... We are surrounded by the word" diet" everywhere we look
and listen. We have so easily been attracted by the promise and
potential of diet products that we have stopped thinking about what
diet products are doing to us. We are paying for products that
harm us psychologically and physically (身体上).
Diet products significantly weaken us psychologically. On one
level, we are not allowing our brains to admit that our weight
problems lie not in actually losing the weight, but in controlling
the consumption of fatty, high-calorie, unhealthy foods. Diet
products allow us to jump over the thinking stage and go straight
for the scale (秤) instead. All we have to do is to swallow or
recognize the word" diet" in food labels.
On another level, diet products have greater psychological
effects. Every time we have a zero-calorie drink, we are telling
ourselves without our awareness that we don't have to work to get
results. Diet products make people believe that gain comes without
pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological
effects they have on us, but also in the physical harm that they
cause. Diet foods can indirectly harm our bodies because
consuming them instead of healthy foods means we are preventing
our bodies from having basic nutrients (营养成分). Diet foods
and diet pills contain zero calorie only because the diet industry
has created chemicals to produce these wonder products. Diet
products may not be nutritional, and the chemicals that go into diet
products are potentially dangerous.
Now that we are aware of the effects that diet products have
on us, it is time to seriously think about buying them. Losing
weight lies in the power of minds, not in the power of chemicals.
Once we realize this, we will be much better able to resist diet
products, and therefore prevent the psychological and physical
harm that comes from using them.

Professor Barry Wellman of the University of Toronto in Canada has invented a term to describe the way many North Americans interact(互动)these days.The term is “networked individualism”.This concept is not easy to understand because the words seem to have opposite meanings.How can we be individuals(个体)and be networked at the same time?You need other people for networks.
Here is what Professor Wellman means.Before the invention of the Internet and e-mail,our social networks included live interactions with relatives,neighbors,and friends.Some of the interaction was by phone,but it was still voice to voice,person to person,in real time.
A recent research study by the Pew Internet and American Life Project showed that for a lot of people,electronic interaction through the computer has replaced this person-to-person interaction.However,a lot of people interviewed for the Pew study say that’s a good thing.Why?
In the past,many people were worried that the Internet isolated(孤立)us and caused us to spend too much time in the imaginary world of the computer.But the Pew study discovered that the opposite is true.The Internet connects us with more real people than expected—helpful people who can give advice on careers,medical problems,raising children,and choosing a school or college.About 60 million Americans told Pew that the Internet plays an important role in helping them make major life decisions.
Thanks to the computer,we are able to be alone and together with other people—at the same time!
The underlined phrase “networked individualism”probably means that by using computers people_______.
A.stick to their own ways no matter what other people say

D.are able to keep to themselves but at the same time reach out to other people
According to the Pew study,what do many people rely on to make major life decisions?
A.Networks. B.Friends.
C.Phones. D.Parents.
It can be inferred from the Pew study that_______.
A.people have been separated from each other by using computers
B.the Internet makes people waste a lot of time and feel very lonely
C.the Internet has become a tool for a new kind of social communication
D.a lot of people regard the person-toperson communication as good thing

查看习题详情和答案>>Dreams are expressions of thoughts, feelings and events that pass through our mind while we are sleeping. Everybody dreams. But only some people remember their dreams. Our dreams often include all the senses (感觉)—smells, sounds, sights, tastes and things we touch. We dream in colour. Sometimes we dream the same dream over and over again. These repeated（重复的） dreams are often unpleasant. They may even be nightmares—bad dreams that frighten us.
Early in the twentieth century, two famous scientists developed their personal ideas about dreams. Austrian psychiatrist(心里学家) Sigmund Freud published a book called “The Interpretation(诠释) of Dreams” in 1900. Freud believed people often dream about things they want but can’t have. These dreams often have something to do with sex and aggression(侵犯). Swiss psychiatrist Carl Jung worked closely with Freud for several years, but he believed dreams could help people grow and understand themselves. He believed dreams provide solutions(解答) to problems we face when we are awake. He didn’t believe dreams hide our feelings about sex or aggression. Today we know more about the science of dreaming because researchers can take pictures of people’s brains while they are sleeping.
Other researchers are studying how dreaming helps our bodies work with problems and very sad emotions(感情). Robert Stickgold is a professor of psychiatry at Harvard University in Massachusetts. Doctor Stickgold says that when we dream, the brain is trying to make sense of the world. He does not agree with Sigmund Freud that dreaming is the way we express our hidden feelings and desires(愿望).
Scientists believe it is important to keep researching dreams. Doctor Stickgold says it has been more than one hundred years since Sigmund Freud published his important book about dreaming. Yet there is still no agreement on exactly how the brain works when we are dreaming or why we dream.

查看习题详情和答案>>On June 17, 1774, the officials from Maryland and Virginia held a talk with the Indians of the Six Nations. The Indians were invited to send boys to William and Mary College. In a letter the next day they refused the offer as follows:
We know that you have a high opinion of the kind of learning taught in your colleges, and that the costs of living of our young men, while with you, would be very expensive to you. We are sure that you mean to do us good by your proposal（提议）; and we thank you heartily. But you must know that different nations have different ways of looking at things, and you will therefore not be offended（冒犯） if our ideas of this kind of education happen not to be the same as yours. We have had some experience of it. Several of our young people were formerly brought up at the colleges of the northern provinces: they were taught all your sciences; but when they came back to us, they were bad manners, ignorant（无知的）of every means of living in the woods–they were totally good for nothing.
We are, however, not the less thankful by your kind offer, though we refuse to accept it; and, to show our grateful sense of it, if the gentlemen of Virginia will send us a dozen of their sons, we will take care of their education, teach them in all we know, and make men of them.
The tone(语气) of the letter as a whole is best described as________.
A. angry B. pleasant C. polite D. ambitious
