In the 1950s, the pioneers of artificial intelligence (AI) predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our housework. But as useful as computers are, they’re nowhere close to achieving anything remotely resembling these early aspirations for humanlike behavior. Never mind something as complex as conversation: the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of tasks for a ten-month-old kid.
A growing group of A1 researchers think they know where the field went wrong. The problem, the scientists say, is that Al has been trying to separate the highest, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step programs. A new movement in Al, on the other hand, takes a closer look at the more roundabout way in which nature came up with intelligence. Many of these researchers study evolut

Fifty is the gateway to the most liberating passage in a woman’s life. Children are making test flights out of the nest. Parents are expected to be roaming in their recreational vehicles or sending postcards of themselves riding camels. Free at last! Women can graduate from the precarious balancing act between parenting and pursuit of a career. That has been the message of my books since I wrote New Passages 15 years ago. What I didn’t see coming was the boomerang.
With parents living routinely into their 90s, a second round of caregiving has become a predictable crisis for women in midlife. Nearly 50 million Americans are taking care of an adult who used to be independent. Yes, men represent about one third of family caregivers, but their participation is often at a distance and administrative. Women do most of the hands-on care.

| Stratford-on-Avon, as we all know, has
only one industry -- William Shakespeare -- but there are two distinctly
separate and increasingly hostile branches. There is the Royal Shakespeare
Company (RSC), which presents superb productions of the plays at the Shakespeare
Memorial Theatre on the Avon. And there are the townsfolk who largely live off
the tourists who come, not to see the plays, but to look at Anne Hathaway’s
Cottage, Shakespeare’s birthplace and the other sights. The worthy residents of Stratford doubt that the theatre adds a penny to their revenue. They frankly dislike the RSC’s actors, those with their long hair and beards and sandals and noisiness. It’s all deliciously ironic when you consider that Shakespeare, who eams their living, was himself an actor (with a beard) and did his share o A. the townsfolk despise the RSC’s actors B. the two branches of the RSC do not get along well C. the RSC produces limited quantity of plays D. the townsfolk deny the RSC’s contribution to the town’s revenue [单选题]单相电能表安装完成后，抄录电能表示数、()等相关数据，填写装表工作票各项内容，且要求用户签名认可

More Than 8 Hours Sleep Too Much of a Good Thing
1 .Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences. 2 .Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night.People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night's sleep than 8-hour sleepers. 3 .These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine,demonstrate that people who want to get a good night's rest may not need to set aside. More than 8 hours a night.He added that“it might be a good idea” for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cautioned that more research is needed to confirm this. 4 .Previous studies have shown the potential dangers of chronic shortages of sleep一for instance,one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5 .For the current report,Kripke reviewed the responses of 1,004 adults to sleep questionnaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems.Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning. 6 .Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed.As evidence,he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake.”he said.
