单选题{{B}}Passage 2{{/B}} With the US economy slowing down, layoffs are everywhere. No industry is spared. If you end up having to start over, in addition to starting your job search, there are several things you should take care of to make your transition a smooth one. First and foremost, clear up any misunderstanding about how and why you left your last job with your ex-boss. Whether you left voluntarily, were fired or were laid off due to budget cutbacks, make sure you both have the same explanation. Agree on job titles accordingly. Also ask for a reference if you think your ex-boss will offer one and you trust that he or she will speak honestly about your performance. You should have a source of emergency cash that you can use in the interim. Don't panic and liquidate your stocks and bonds just yet, be optimistic in your prospects while also be more frugal than usual. You should save money on not having to dry clean work clothes so often and eating less take-out lunches. Save money by not eating out at restaurants and watch videos rather than going to the movies every weekend. Make a note of your job hunting expenses, such as career counselors' consulting fees and resume printing costs, and save the receipts. By next year's tax-filing time, you could get deductions on your job-search expense (unless you left a job willingly or was a college graduate looking for your first job). Most companies terminate your medical insurance coverage as soon as you stop working for them. But it doesn't mean you have to forgo medical coverage altogether. There is something called Consolidated Omnibus Budget Reconciliation Act (COBRA) in the United States that legally protects an ex-employee's right to stay in the company's health care plan. However, the company will stop paying your premiums, and you will have to pay out of your pocket the expenses. This is still a good option compared to no health insurance at all. Another important thing to take care of when you change jobs is your 401(k) account. A 401(k) is the retirement fund that most companies offer. It's named after section 401(k) in the Internal Revenue Service's policy documents. You put aside a percentage of your paycheck each pay period, and the money accumulated will be managed by the 401(k) fund manager your employer has hired and is invested in the stock market. You cannot withdraw money from this account until you reach this age, or you will incur penalties. When you leave a job, the money can sometimes be kept with your ex-employer for a while. It's always a good idea to compare your new employer's 401(k) plan with your old one. Every company offers different types of investment options, from overseas stocks to high-tech stocks and everything in between. If you do want to transfer the account to your new employer, you need to go to the human resources department and ask for forms that help you make the transition. Don't forget to ask for job leads from your ex-coworkers. Even if you are leaving for a job in another industry, you never know what people they happen to know that can help with your job search. Keep in touch with the friends you have made at your old job. Remember to anchor yourself to people, not institutions, and you will find that any transition is made easier.

单选题How much sleep does a person need? (31) the physiological bases of the need for sleep remain conjectural (猜想), rendering conclusive answers to this question impossible, much evidence has been gathered on how much sleep people do in fact obtain. Perhaps the most important conclusion to be (32) from this evidence is (33) there is great variability among individuals in total sleep time. For adults, (34) between six and nine hours of sleep as a nightly average is not unusual, and 7.5 hours probably best expresses the norm. Such norms, of course, forms inevitably vary with the criteria of sleep employed. The most (35) and reliable figures on sleep time, including those cited here, come from studies in sleep laboratories, where EEG criteria are employed. (36) consistently has been associated with the varying amount, quality, and pattern of electrophysiologically defined sleep. The newborn infant may spend an average of about 16 hours of each 24-hour period in sleep, (37) the sleep time drops sharply; by two years of age, it may (38) from nine to 12 hours. Decreases to approximately six hours have been observed among the elderly. (39) will be discussed from below, EEG sleep studies have indicated that sleep can be considered to consist of several different stages. Developmental changes in the relative proportion of sleep time (40) in these sleep stages are as striking as age-related changes in total sleep time.

单选题"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," declared 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 agreed, "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, telephones 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 on? 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.
