The baby is just one day old and has not yet left hospital. She is quiet but alert (警觉). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus — until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?
Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise (同样地) when the researchers started with drumbeats and moved to spots.
The experiment described in Paragraph 1 is related to the baby’s__.

A.sense of hearing B.sense of sight
C.sense of touch D.sense of smell

Babies are sensitive to the change in______.

A.the size of cards B.the colour of pictures
C.the shape of patterns D.the number of objects

Why did the researchers test the babies with drumbeats?

A.To reduce the difficulty of the experiment.
B.To see how babies recognize sounds.
C.To carry their experiment further.
D.To keep the babies’ interest.

Where does this text probably come from?

A.Science fiction. B.Children’s literature.
C.An advertisement. D.A science report.

The Healthy Habits Survey(调查)shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.
1. How many times did you brush your teeth yesterday?
·Finding:A full 33% of seniors brush their teeth only once a day.
·Step:Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.
2.How many times did you wash your hands or bathe yesterday?
·Finding:Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day—half of the number doctors recommend.
·Step:We touch our faces around 3,000 times a day—often inviting germs(病菌)to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.
3. How often do you think about fighting germs?
·Finding:Seniors are not fighting germs as well as they should.

Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.
According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers’ markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.
After a visit to the United States, Mireille Guiliano, author of French Women Don’t Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.
In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity — or extreme overweight — among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17% — and is growing.
In what way are the French different from Americans according to Dr. Joseph Mercola?

A.They go shopping at supermarkets more frequently.
B.They squeeze eating between the other daily activities.
C.They usually eat too much canned and frozen food.
D.They regard eating as a key part of their lifestyles.

When I told my father that I was moving to Des Moines, Iowa, he told me about the only time he had been there. It was in the 1930s, when he was an editor of the literary magazine of Southern Methodist University(SMU)in Dallas, Texas. He also worked as a professor at SMU, and there was a girl student in his class who suffered from a serious back disease. She couldn’t afford the operation because her family was poor.
Her mother ran a boardinghouse in Galveston, a seaside town near Houston, Texas. She was cleaning out the attic(阁楼)one day when she came across an old dusty manuscript(手稿). On its top page were the words, “By O. Henry”. It was a nice story, and she sent it to her daughter at SMU, who showed it to my father. My father had never read the story before, but it sounded like O. Henry, and he knew that O. Henry had once lived in Houston. So it was possible that the famous author had gone to the beach and stayed in the Galveston boardinghouse, and had written the story there and left the manuscript behind by accident. My father visited an O. Henry expert at Columbia University in New York, who authenticated the story as O. Henry’s.
My father then set out to sell it. Eventually, he found himself in Des Moines, meeting with Gardner Cowles, a top editor at the Des Moines Register. Cowles loves the story and bought it on the spot. My father took the money to the girl. It was just enough for her to have the operation she so desperately needed.
My father never told me what the O. Henry story was about. But I doubt that it could have been better than his own story.
Who found the O. Henry’s manuscript?

A.The author. B.The author’s father.
C.The girl. D.The girl’s mother

Which of the following might explain the fact that the manuscript was found in the attic?

A.O. Henry once worked in Houston.

Arriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a house for me and our children.
During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.
He reported the case to the police and then sat there, lost and lonely in a strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.
Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband’s name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can(垃圾桶)that had been left out on the footpath.
My husband rushed to their home to find a kind family holding all his papers and documents(文件). Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.
That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.
