That shabby unknown bundle of neglect and despair that was dropped off by the police six weeks ago—later to be identified by his mother, who turns up occasionally—is now a driving force on the infants’ ward. Once he was bathed a few times and his rashes were treated, he turned out to be a 14-month-old boy named Vergil, still recovering from premature birth——birth weight, 2.5 pounds, it came obvious he had never received any real attention, and practical no solid food, and it was never very clear who assumed responsibility for him in his family, if anyone. Miraculously he survived, with almost no outside help.At first he just lay there, withdrawn, sucking on an empty bottle as he had been used to doing at home. After a few days it became clear he was ravenously hungry and he downed bottle after bottle of milk. Slowly he began to respond to the ward staff around him who hung over the side of his crib, tempting him back to life.He started by cautiously chewing on people, sniffing and tasting them warily like a little wild creature. Gradually he climbed to a standing position, pulling himself up on the bars of his crib. Then he began to discover noise——that came from himself. When he learned that it was acceptable, in this place, to scream when enraged, he filled his corner of the room with garbled speech-like sounds, and loud baby-bellows of demand. If nobody responded he would fix each passerby with a coy look that evolved into a seductive grin, revealing four widely space little teeth. Someone always stopped, grinning back at this adorable creature, then picking him up and cuddling him. We on the staff took personal pride and delight in his steady progress.During the day we moved his crib from the infants' ward to the playroom where there are people coming and going. He loved it, standing and cruising in his crib, commenting happily on the scene, crowing and babbling. One afternoon, when his crib was moved adjacent to the wall, he became unusually quiet, deep in concentration. With the stealth of a cat, using his little fingers like tiny screwdrivers, he had taken apart the wall oxygen unit. Our delight in his progress turned to real respect. Perhaps we could steer him toward the right path before it was too late.Vergil definitely had a future.1.In the infants’ ward, Vergil （ ）.2.The ward staff must have been marveled at Vergil's（ ）.3.How did Vergil begin to respond to people?4.

A report consistently brought back by visitors to the US is how friendly, courteous, and helpful most Americans were to them. To be fair, this observation is also frequently made of Canada and Canadians, and should best be considered North American. There are, of course, exceptions. Small-minded officials, rude waiters, and ill-mannered taxi drivers are hardly unknown in the US. Yet it is an observation made so frequently that it deserves comment.For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence. Dullness and loneliness were common problems of the families who generally lived distant from one another. Strangers and travelers were welcome sources of diversion, and brought news of the outside world.The harsh realities of the frontier also shaped this tradition of hospitality. Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the nearest cabin or settlement. It was not a matter of choice for the traveler or merely a charitable impulse on the part of the settlers. It reflected the harshness of daily life: if you didn’t take in the stranger and take care of him, there was no one else who would. And someday, remember, you might be in the same situation.Today there are many charitable organizations that specialized in helping the weary traveler. Yet, the old tradition of hospitality to strangers is still very strong in the US, especially in the smaller cities and towns away from the busy tourist trails. I was just traveling through, got talking with this American, and pretty soon he invited me home for dinner—amazing. Such observations reported by visitors to the US are not uncommon, but are not always understood properly. The casual friendliness of many Americans should be interpreted neither as superficial nor as artificial, but as the result of a historically developed cultural tradition.As is true of any developed society, in America a complex set of cultural signals assumptions, and conventions underlies all social interrelationships. And, of course, speaking a language does not necessarily mean that someone understands social and cultural patterns. Visitors who fail to translate cultural meanings properly often draw wrong conclusions. For example, when an American uses the word friend, the cultural implications of the word may be quite different from those it has in the visitor’s language and culture. It takes more than a brief encounter on a bus to distinguish between courteous convention and individual interest. Yet, being friendly is a virtue that many Americans value highly and expect from both neighbors and strangers.1.The word “observation” in the first paragraph most probably means （ ）.2.People in frontier settlements used to entertain travelers because these strangers would （ ）.3.Nowadays the tradition of friendliness to strangers （ ）.4.According to the passage, which of the following is true?5.From the last paragraph of the passage we have learned that（ ）.
