Animals seem to have the sense (本能) to eat when they are hungry and they do not eat more than their bodies need.It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant(香的) flavor (味道) was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water.In time, however, they broke the habit and went back to where the necessary vitamins were.
In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria(自助) feeding arrangement, with a wide selection of baby food before them.They were given whatever food they pointed to or appeared interested in.We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet.
So, in selecting food, rats and babies do seem to know and act on what's best for them.Apparently, there is a kind of “body wisdom”, which humans soon lose. Most of us do not eat as wisely as we could.Many of our food preferences are culturally determined and influenced by long-established(长期养成的)habits.Some people eat foxes, dogs and blackbirds, while we eat cows and pigs.So what people eat and how much they eat seems to be greatly influenced by what is going on around them.
53.The expression “the habit” in paragraph 1 refers to drinking water which _______.
A. has no smell    B. is tasteless    C. has vitamins   D. is flavored (有味道的)
小题1:According to the passage, adults eating habits differ from those of babies because _______.
A.adults know better than babies what kind of food are good for their health
B.adults usually cannot resist (抵制) the temptation (诱惑) of various delicious foods
C.adults' eating habits are closely related to the social and cultural customs
D.adults have more choices of food than babies in eating patterns
小题2:The author implied in the passage that most of us _______.
A.eat a balanced diet
B.choose the food that is of nutrition
C.have the habits influenced by the surroundings
D.like to eat the food with a fragrant flavor.
小题3:As far as their eating habits are concerned, babies and rats are similar in that _______.
A.both have the wisdom to choose a balanced diet
B.both prefer flavored food and drink
C.both have the same eating patterns
D.both develop a taste for the same kinds of flavors

My elder brother Steve, in the absence of my father who died when I was six, gave me important lessons in values that helped me grow into an adult.
For instance, Steve taught me to face the results of my behavior. Once when I returned in tears from a Saturday baseball game, it was Steve who took the time to ask me what happened. When I explained that my baseball had soared through Mrs. Holt’s basement window, breaking the glass with a crash, Steve encouraged me to confess(承认)to her. After all, I should have been playing in the park down Fifth Street and not in the path between buildings. Although my knees knocked as I explained to Mrs. Holt, I offered to pay for the window from my pocket money if she would return my ball. I also learned from Steve that personal property is a sacred(神圣的) thing. After I found a shiny silver pen in my fifth-grade classroom, I wanted to keep it, but Steve explained that it might be important to someone else in spite of the fact that it had little value. He reminded me of how much I’d hate to lose to someone else the small dog that my father carved from a piece of cheap wood. I returned the pen to my teacher, Mrs. Davids, and still remembered the smell of her perfume as she patted me on my shoulder.
Yet of all the instructions Steve gave me, his respect for life is the most vivid in my mind. When I was twelve, I killed an old brown sparrow in the yard with a BB gun. Excited with my accuracy, I screamed to Steve to come from the house to take a look. I shall never forget the way he stood for a long moment and stared at the bird on the ground. Then in a dead, quiet voice, he asked, “Did it hurt you first, Mark?” I didn’t know what to answer. He continued with his eyes firm, “The only time you should even think of hurting a living thing is if it hurts you first. And then you think a long, long time.” I really felt terrible then, but that moment stands out as the most important lesson my brother taught me.
小题1: What is the main subject of the passage?
A.The relationship between Mark and Steve.
B.The important lesson Mark learned in school
C.Steve’s important role in mark’s growing process.
D.Mark and Steve’s respect for living things.
小题2:It can be inferred from the passage that when Mark confessed to Mrs. Holt, __________.
A.he felt surprisedB.he was light-hearted
C.he felt frightened D.he knelt before her
小题3:In the story about the pen, which of the following lessons did Steve teach his brother?
A.Respect for personal property.B.Respect for life.
C.Sympathy for people with problems.D.The value of honesty.
小题4:According to the writer, which was the most important lesson Steve taught his young brother?
A.Respect for living things.B.Responsibility for one’s actions.
C.The value of the honesty.D.Care for the property of others.
小题5:Which of the follow is true according to the passage?
A.Mark was still a boy when he wrote this passage.
B.Mark lost the small dog his father carved somewhere.
C.When a living thing hurts you, you should kill it.
D.Even if a living thing hurts you, you should not kill it without hesitation.
ROME: The legend of Leonardo da Vinci is covered in mystery: How did he die?Are the remains buried in a French castle really those of the master? Was the "Mona Lisa" a self-portrait in disguise (伪装)?
A group of Italian scientists believe the key to solving those puzzles lies with the remains, and they say they are seeking permission to dig up the body to conduct carbon and DNA testing.
If the skull is undamaged, the scientists can go to the heart of a question that has fascinated scholars and the public for centuries: the identity of the "Mona Lisa." Recreating a virtual and then physical reconstruction of Leonardo's face, they can compare it with the smiling face in the painting.
"We don't know what we'll find if the tomb is opened. We could even just find grains and dust," says Giorgio Gruppioni, an anthropologist who is participating in the project. "But if the remains are well kept, they are a biological record of events in a person's life, and sometimes in their death." Silvano Vinceti, the leader of the group, said that he plans to press his case with the French officials in charge of the said burial site at Amboise Castle early next week.
Leonardo moved to France at the invitation of King Francis I, who named him "first painter to the king." He spent the last three years of his life there, and died in 1519 at age 67. The artist's original burial place, the palace church of Saint Florentine, was destroyed during the French Revolution and remains that are believed to be his were eventually reburied in the Saint-Hubert Chapel near the castle.
"The Amboise tomb is a symbolic tomb; it's a big question mark," said Alessandro Vezzosi, the director of a museum dedicated to Leonardo in his hometown of Vinci. Vezzosi said that investigating the tomb could help identify the artist's bones with certainty and solve other questions, such as the cause of his death. He said he asked to open the tomb in 2004 to study the remains, but the Amboise Castle turned him down.
The group of 100 experts involved in the project, called the National Committee for Historical and Artistic Heritage, was created in 2003 with the aim of "solving the great mysteries of the past," said Vinceti, who has written books on art and literature.
Arguably the world's most famous painting, the "Mona Lisa" hangs in the Louvre in Paris, where it drew some 8.5 million visitors last year. Mystery has surrounded the identity of the painting's subject for centuries, with opinions ranging from the wife of a Florentine merchant to Leonardo's own mother.
That Leonardo intended the "Mona Lisa" as a self-portrait in disguise is a possibility that has interested and divided scholars. Theories have existed: Some think that Leonardo's taste for tricks and riddles might have led him to hide his own identity behind that puzzling smile; others have guessed that the painting hid an androgynous lover.
If granted access to the grave site, the Italian experts plan to use a tiny camera and radar to confirm the presence of bones. The scientists would then exhume (挖掘) the remains and attempt to date the bones with carbon testing.
At the heart of the proposed study is the effort to discover whether the remains are actually Leonardo's, including with DNA testing.
Vezzosi questions the DNA comparison, saying he is unaware of any direct descendants (后代) of Leonardo or of tombs that could be attributed with certainty to the artist's close relatives.
Gruppioni said that DNA from the bones could also eventually be compared to DNA found elsewhere. For example, Leonardo is thought to have rubbed colors on the canvas with his thumb, possibly using saliva (唾液), meaning DNA might be found on his paintings.
Even in the absence of DNA testing, other tests could provide useful information, including whether the bones belonged to a man or a woman, and whether the person died young or old.
Even within the committee, experts are divided over the identity of the "Mona Lisa."
Vinceti believes that a tradition of considering the self-portrait to be not just a faithful imitation of one's features but a representation of one's spiritual identity may have resonated (共鸣) with Leonardo.
Vezzosi, the museum director, dismissed as "baseless and senseless" the idea that the "Mona Lisa" could be a self-portrait of Leonardo. He said most researchers believe the woman may have been either a wife of the artist's sponsor, the Florentine nobleman Giuliano de Medici, or Lisa Gherardini, the wife of a rich silk merchant, Francesco del Giocondo. The traditional view is that the name "Mona Lisa" comes from the silk merchant's wife, as well as its Italian name: "La Gioconda."

On the day Apple debuted the often-delayed white-colored iPhone 4, the company's marketing department gave a nod to the product's troubled history.
"Finally." read the big headline Thursday above a picture of the white phone on the homepage of Apple.com.
The white model was supposed to ship alongside the black one at the iPhone 4's launch(推出) last June.But design and manufacturing complications delayed the process by 10 months, catching Apple off guard, executives say.
As CNN reported last month, earlier test models of the white iPhone 4 produced unclear photos, especially when the flash(闪光灯) was used.Its whiteness confused the proximity sensor (距离传感器) , which detects when the phone is held next to someone's head and turns off the touch screen to save battery life.
These problems weren't present in older iPhones that came in white because they didn't have flash photography; the proximity sensor was unaffected because the front side of previous models was black.
"We thought we were there a year ago, or less than that, when we launched the iPhone 4, and we weren't," Philip Schiller, Apple's chief marketing executive, said in an interview."It's not as simple as making something white.There's a lot more that goes into both the material science of it —how it holds up over time…but also in how it all works with the sensors."
Ticonderoga Securities analyst Brian White predicts that the white model could help drive sales of Apple's phones.He says Apple could sell 1 million to 1.5 million every three months until the next iPhone model is unveiled, which is expected to be this fall.
Forty-five people were lined up at Apple's flagship New York store Thursday morning to buy white iPhones, according to a CNN Money report.
小题1:The reason why white-colored iPhone 4 was delayed by 10 months is that _______.
A.it's always sold out due to its popularity
B.it met some problems concerning design and manufacture
C.it lacked white manufacturing materials
D.its proximity sensor can't save battery life
小题2:According to the passage, which of the following statements is TRUE?
A.There are multi-colored models of iPhone 4.
B.The same design problems were also found in older white iPhones.
C.IPhone4 will be launched this fall.
D.Originally designers thought they could solve the problems before iPhone 4 was launched.
小题3:What would be the best title for this passage?
A.Why the White iPhone 4 Took So Long
B.The History of iPhone 4
C.The Attraction of White iPhone 4
D.The Design and Manufacture of iPhone 4
