For most, that meant starting a family. Between 1946 and 1960, 63 million babies were born in the United States, up 22 million from the fifteen-year period before that. this big jump in the birth rate came to be known as the baby boom (婴儿潮). Before the war, American children were raised very strictly. They were often told to be "seen and not heard." After the war, however, young parents raised their children according to different ideas. Dr. Benjamin Spock's Common Sense Book of Baby and Child Care, published in 1946, emphasized flexibility (灵活性) in raising children. Spock encouraged parents to listen to their children and respond to their wishes. New parents quickly made Dr. Spock's book the best-selling book in US history. By 1952, sales had reached 4 million copies per year for the next eighteen years. Critics (批评家) who believed that the old ways of raising children were best accused Spock of being too permissive. They thought his ideas would spoil children. But Spock opposed strict discipline because he thought there were was "no such thing as a bad boy." By this he meant that, although a child's behavior may be bad, the child is not. Millions of baby-boom parents were influenced by Spock's advice, which brought a revolution in the way children were raised.• 1.

One couple in Sweden decided to take that logic a few steps further, and are refusing to tell anyone whether their child is a boy or a girl. The child – called Pop, to protect his or her identity –is now two years old, and only a few clo se relatives know the sex. “We want Pop to grow up more freely,” Pop’s mother said. Pop wears dresses, and also “male” styled pants and Pop’s hairstyle changes often. Nordenstrom, who studies hormonal (荷尔蒙) influences on gender, says, “It will affect the c hild, but it’s hard to say if it will hurt the development. I don’t know what they are trying to achieve. It’s going to make the child different.” She says if Pop is still “genderless(无性的)” by the time he or she starts school, Pop will certainly receive a lot of attention from classmates. “We don’t know exactly what determines sexual identity, but it’s not only sexual education,” says Nordenstrom. “Gender-typical behavior, sexual preferences and sexual identity usually go together. There are hormonal and ot her influences that we don’t know that will determine the gender of the child.” Pop will soon welcome a brother, or a sister. Pop’s parents will not reveal the sex of that child, either, except, perhaps, to Pop.• 1. What did the couple in Sweden do to their child?• A. They taught their child to take a few steps further. B. They didn't want anyone to know the sex of their baby before it was born. C. They are refusing to tell the sex of their child. D. They refused to let their relatives get close to their child.• 2. Why was the child called Pop?• A. It is a very beautiful name for a child. B. The parents want this name to bring the child good luck. C. It is a very meaningful name. D. The name makes it hard for others to tell the sex of the baby.• 3. What can we learn from what Nordenstrom said?• A. It's hard to tell whether the influence on the child will be good or bad. B. The child will become abnormal (反常的). C. The child is neither a boy nor a girl because it is "genderless." D. Hormonal influence will determine the gender of the child.• 4.

One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one’s own. Then, in the country one can really get away from the noise and hurry of busy working lives. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one’s free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has got the reward together with those who have shared the secret of Nature. Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight’s (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night.• 1. Which of the following statements is NOT true? ___________• A. People who love Nature prefer to live outside the city. B. People who work in London prefer to live in the country. C. Some people enjoying city life prefer to work and live inside London. D. Many nature lovers, though working in London, prefer to live outside the city.• 2. With the same money __________, one can buy a little house with a garden in the country.• A. getting a small flat with a garden B. having a small flat with a garden C. renting a small flat without a garden D. buying a small flat without a garden• 3. When the garden is in blossom, it means that one ___________ if they had to live outside London.• A. living in the country B. having spend time working in the garden C. having a garden of his own D. having been digging, planting and watering• 4. People who think happiness lies in the town would feel that __________ if they had to live outside London.• A. their life was meaningless B. their life was invaluable C. they didn't deserve a happy life D. they were not worthy of their happy life• 5.
