C A four-year study done by Infant (幼儿) Testing Center in San Francisco, California, suggests that babies feel more comfortable around other babies than with strange adults. According to the study ,babies benefit by being with their fellow infants daily. While on the other hand, a baby might show fear of an adult stranger, who is likely to smile and reach out for an unfamiliar infant. By the time babies are one year old, they have begun to form friendships of a sort. The above buildings, based on observation(观察) of 100 babies aged three months to three years, might prove interesting to working parents who must find day care for their babies. Family care in a private home, with several babies together, is probably the ideal way to care for babies under three. Dr Benjamin Spocks, well-known pediatrician(儿科医生) and author of books about babies, supports the idea. He says that family day care is sounder(有理由的) in theory than hiring a housekeeper or a babysitter. 51. Which of the following does a baby like to be with best? A. A house keeper. B. A fellow baby. C.

D Dolphins(海豚) are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this way they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brain is nearly the same size as our own, and they live a long time---at least twenty or thirty years. Like some animals, dolphins use sound to help them find their way around .They also make these sounds to talk to each other and to help themselves find food . We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw. Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people. There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903 Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered (恢复) and for nine years more continued to guide all ships through the area---except for the Penguin. Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them. 54. Why did the sailors off the coast of New Zealand look for Jack? A. He was lonely and liked to be with people.B. They enjoyed playing with him. C. He was seriously wounded.D. They wanted his help. 55. By telling the story of Jack the writer wanted to show that_______. A. dolphins are friendly and clever B. people are cruel to animals C. Jack is different from other dolphins D. dolphins should be protected by law E As is true in all cultures, Americans first hear music in the context of family life. Much of that music comes from the records on the family radio or television, and this “canned” music is especially important in developing children’s musical taste. People often say they were very strongly influenced by the kind of music they heard before they were old enough to have their own records or choose the station on the family radio. There is usually some live music in the family as well. Many mothers and grandmothers sing lullabies(催眠曲), for example. These can be important since in America, as elsewhere, lullabies not only lull(催眠) a baby to sleep but promise ,praise and teach cultural values. Some lullabies are the only songs in a foreign language that American children with strong ethnic (种族的) backgrounds hear, since people often fall back on old , familiar languages for intimate(亲密的)songs.
