Sleepwalking is a sleep disorder. Your child will rise from bed and walk or engage in other activities that they would normally do when they are awake. Their eyes will be open but they will appear to be in a dream-like state, and will probably not answer when you talk to them, although they may carry out conversations. Sleepwalking can last a few seconds , a few minutes, or more.
Sleepwalking can be an indication that certain parts of the brain may not be relaxing properly at bedtime. It can be caused by illness or fever, tiredness, stress or anxiety. It is thought to occur in the beginning, slow-wave stages of non-rapid eye movement sleep before dream sleep. It may be related to the lack of magnesium (镁) , and it is very possible that hormonal（荷尔蒙的）changes in body could cause it. Certainly a child is more likely to be a sleepwalker if one of his parents suffered, too .
Sleepwalking itself is not dangerous and is generally not a sign of any more worrying problems. But if your child sleepwalks regularly, you have to take safety measures to make sure that he doesn't hurt himself while sleepwalking. Makes sure that any doors can't be opened by a child, and lock doors to the cellar, kitchen and other dangerous places. Check each night before lights go out for sharp objects or, indeed , anything on the floor which your child could trip over or hurt himself on.
A child may sleepwalk once and never sleepwalk again. Others may sleepwalk once a month or so. Still others may sleepwalk almost nightly. If you are worried you should consult your doctor. What does the second paragraph mainly tell us?

People are being lured (引诱)onto Facebook with the promise of a fun, free service without realizing they're paying for it by giving up loads of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.

He also urged the Federal Trade Commission to set guidelines for social-networking sites."I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them," Schrage admits.

In times of economic crisis. Americans turn to their families for support. If the Great Depression is any guide, we may see a drop in our skyhigh divorce rate. But this won't necessarily represent. an increase in happy marriages. In the long run, the Depression weakened American families, and the current crisis will probably do the same.
We tend to think of the Depression as a time when families pulled together to survive huge job losses, By 1932. when nearly one-quarter of the workforce was unemployed, the divorce rate had declined by around 25% from 1929 But this doesn't mean people were suddenly happier with their marriages. Rather, with incomes decreasing and insecure jobs, unhappy couples often couldn't afford to divorce. They feared neither spouse could manage alone.
Today, given the job losses of the past year, fewer unhappy couples will risk starting separate households, Furthermore, the housing market meltdown will make it more difficult for them to finance their separations by selling their homes.
After financial disasters family members also tend to do whatever they can to help each other and their communities, A 1940 book. The Unemployed Man and His Family, described a family in which the husband initially reacted to losing his job "with tireless search for work."He was always active, looking for odd jobs to do.
The problem is that such an impulse is hard to sustain Across the country, many similar families were unable to maintain the initial boost in morale(士气). For some, the hardships of life without steady work eventually overwhelmed their attempts to keep their families together. The divorce rate rose again during the rest of the decade as the recovery took hold.
Millions of American families may now be in the initial stage of their responses to the current crisis, working together and supporting one another through the early months of unemployment.
Today's economic crisis could well generate a similar number of couples whose relationships have been irreparably(无法弥补地)ruined. So it's only when the economy is healthy again that we'll begin to see just how many broken families have been created.In the initial stage, the current economic crisis is likely to __________.

| A．It will force them to pull their efforts together |
| B．It will undermine their mutual understanding |

Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn’t it?
While such vigilant(警觉的)tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.
In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups.
It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(预期寿命).
A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population.
It’s not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care.”
That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.Why do doctors recommend routine cancer screening for elderly people?
| A．It is believed to contribute to long life. |
| B．It is part of their health care package. |
| C．The elderly are more sensitive about their health. |
| D．The elderly are in greater danger of tumor growth. |
How do some researchers now look at routine cancer screening for the elderly?
| A．It adds too much to their medical bills. |
| B．It helps increase their life expectancy. |
| C．They are doubtful about necessity. |
| D．They think it does more than good. |
What is the conventional view about women screening for breast cancer?
| A．It applies to women over 50. |
| B．It is a must for adult women. |
| C．It is optional for young women. |
| D．It doesn’t apply to women over 74. |
Why do many doctors prescribe routine screening for cancer?
| A．They want to protect themselves against medical disputes. |
| B．They want to take advantage of the medical care system. |
| C．They want data for medical research. |
| D．They want their patients to suffer less. |
What does the author say is the general view about health care?
| A．The more, the better. |
| B．Prevention is better than cure. |
| C．Better early than late. |

As you are probably aware, the latest job markets news isn’t good: Unemployment is still more than 9 percent, and new job growth has fallen close to zero. That’s bad for the economy, of course. And it may be especially discouraging if you happen to be looking for a job or hoping to change careers right now. But it actually shouldn’t matter to you nearly as much as you think.
That’s because job growth numbers don’t matter to job hunters as much as job turnover data. After all, existing jobs open up every day due to promotions, resignations, terminations, and retirements. (Yes, people are retiring even in this economy.) In both good times and bad, turnover creates more openings than economic growth does. Even in June of 2007, when the economy was still humming along, job growth was only 132,000, while turnover was 4.7 million!
And as it turns out, even today — with job growth near zero — over 4 million job hunters are being hired every month.
I don’t mean to imply that overall job growth doesn’t have an impact on one’s ability to land a job. It’s true that if total employment were higher, it would mean more jobs for all of us to choose from (and compete for). And it’s true that there are currently more people applying for each available job opening, regardless of whether it’s a new one or not.
But what often distinguishes those who land jobs from those who don’t is their ability to stay motivated. They’re willing to do the hard work of identifying their valuable skills; be creative about where and how to look; learn how to present themselves to potential employers; and keep going, even after repeated rejections. The Bureau of Labor Statistics data shows that 2.7 million people who wanted and were available for work hadn’t looked within the last four weeks and were no longer even classified as unemployed.
So don’t let the headlines fool you into giving up. Four million people get hired every month in the U.S. You can be one of them.The author tends to believe that high unemployment rate ______?
| A．deprives many people of job opportunities. |
| B．prevents many people from changing careers. |
| C．should not stop people from looking for a job. |
| D．does not mean the U.S. economy is worsening. |
Where do most job openings come from?
| A．Job growth |
| B．Job turnover |
| C．Improved economy |
| D．Business expansion |
What does the author say about overall job growth?
| A．It doesn’t have much effect on individual job seekers. |
| B．It increases people’s confidence in the economy. |
| C．It gives a ray of hope to the unemployed. |
| D．It doesn’t mean greater job security for the employed. |
What is the key to landing a job according to the author?
| A．Education |
| B．Intelligence |
| C．Persistence |
| D．Experience |
What do we learn from the passage about the unemployment figures in the US?
| A．They clearly indicate how healthy the economy is. |
| B．They provide the public with the latest information. |
| C．They warn of the structural problems in the economy. |
| D．They exclude those who have stopped looking for a job. |
