“There is an out – of – date idea that children grow up and leave home when they’re 18,and the truth is far from that,” says Mr．Larry Bumpass of the University of Wisconsin．Today unexpected numbers of young adults are living with their parents．“There is a great change in the middle class,” declares Allan Schnaiberg of Northwestern University, whose son, 19, moved back in after an absence of eight months．
Scientists show a number of reasons for this return to the nest．The marriage age is rising, a condition that makes home and its pleasantness particularly attractive to young people．A high divorce （离婚） rate and a low remarriage rate make some differences．For some, the expense of an away - from - home college education has become so great that many students now attend local schools．Even after graduation, young people find their wings tied by terrible housing costs．
Living at home, says Knighton, a school teacher, continues to give security （安全保卫） and moral（道义的） support．Her mother agreed．“Its strange for the kids to pay all that money for rent．It makes sense for kids to stay at home．” But sharing the family home requires changes for all．There are the hassles over bathrooms, telephones and privacy．Some families, however, manage the careful balancing act．But for others, it proves too difficult．Michelle Del Turco, 24, has been home three times and left three times．“What I considered a social drink, my dad considered an alcohol （酒精） problem,” she explains．“He never liked anyone I dated, so I either had to hide away or meet them at friends' houses．”
Just how long should adult children live with their parents before moving on? Most scientists feel lengthy homecomings are a mistake．Children, can end up with a sense of defeat and failure．And aging parents, who should be enjoying some freedom, find themselves stuck with too many things．Many agree that brief visits, however, can work well．

Calvin Coolidge (1872 – 1933) was the thirtieth president of the United States. He looked down on a person as being unworthy of respect who was too fond of talking about the details of others people’s actions and private lives because he had no time for small talks. The following two incidents clearly show how Collidge treasured silence.
When he was vice president, Coolidge had plenty of opportunities to participate (参加) in Washington’s social life, especially the many dinner parties. As be ignored the art of conversation, he couldn’t exactly make himself dear to his hostesses. One lady felt she could solve this problem. She placed him next to Alice Roosevelt Longworth, daughter of the former President Roosevelt. Mrs. Longworth, a very brilliant conversationalist (谈话者), began to talk in her usual charming manner, but all attempts to a wake the interest on the part of the vice president were unproductive. Finally, being shamed into anger, she said, “I’m sure that going to as many dinners as you do, you must get terribly bored.”
Without lifting his eyes from his plate, Coolidge said not very clearly, “Well, a man has to eat somewhere.”
Later, when he was president and once again at a dinner party, Collidge was seated next to an outstanding society woman, one of those busybodies, who seemed to take delight in trying to change the lives of everyone they met. “Oh, Mr. President,” she spoke with too much enthusiasm, “you are always so quiet. I made a bet (打赌) today that I could get more than two words out of you.”

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

  A. depend on one sense in choosing food            B. are not satisfied with their food
