"There is a senseless notion that children grow up and leave home when they're 18, and the truth is far from that," says sociologist Larry Bumpass of the University of Wisconsin. Today, unexpected numbers of young adults are living with their parents. "There is a major shift in the middle class,' declares sociologist Allan Schnaiberg of Northwestern University, whose son, 19, moved back in after an absence of eight months.
Analysts cite a variety 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 rate and a declining remarriage rate are sending economically pressed and emotionally hurt survivors back to parental shelters. For some, the expense of an away-from- home college education has become so excessively great that many students now attend local schools. Even after graduation, young people find their wings clipped by skyrocketing housing costs.
Living at home, says Knighton, a school teacher, continues to give her security and moral support. Her mother agrees, "It's ridiculous 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 adjustments for all. There are the hassles over bathrooms, telephone and privacy. Some families, however, manage the delicate 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 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 out? Most psychologists feel lengthy homecomings are a mistake. Children, struggling to establish separate identities, can end up with "a sense of inadequacy, defeat and failure." And aging parents, who should be enjoying some financial and personal freedom, find themselves stuck with responsibilities. Many agree that brief visits, however, can work beneficially.

单选题 One of the disadvantages of young adults returning to stay with their parents is that______.
【正确答案】 A
【答案解析】第三段后半部分重点说明了孩子回家与父母住在一起的弊病,而Michelle Del Turco的例子,正好说明孩子与父母住在一起时,他们会引起“the hassles over bathrooms,telephone and privacy”,很显然,这些全是由于孩子与父母同住而引起的日常生活的不便,所以[A]为正确答案。而[B], [C]和[D]所述内容在文中均未提及。
