Computers might not be clever enough to trick adults into thinking they are intelligent yet, but a new study, led by Javier' Movellan at the University of Califomia San Diego, shows that a giggling (咯咯笑的) robot is clever enough to get toddlers (初学走路者) to treat it as a peer (同龄人).

     The researchers stationed a 2-foot-tall robot Called QRIO in a classroom of a dozen toddlers aged between 18 months and two years. QRIO stayed in the middle of the room using its sensors (传感器) to avoid bumping (碰撞) into the kids. It was programmed to giggle when the kids touched its head, to occasionally sit down, and to lie down when its batteries died.

     "We expected that after a few hours, the magic was going to disappear," Movellan says.  "That's what was found with earlier robots." But, in fact, the kids remained interested in the robot over several weeks, eventually communicating with QRIO in much the same way they did with other toddlers.

     The researchers measured the relationship between the children and the robot in several ways. Firstly, as with other toddlers,  they touched QRIO mostly on the arms and hands, rather than on the face or legs. For this age group, "the amount of touching is a good predictor of how you are doing as a social being," Movellan says.

     The children helped the robot up when it fell, and when QRIO's batteries ran out and it lay down, a toddler would come up and cover it with a blanket and say "night, night". However, when QRIO was programmed to spend all its time dancing, the kids quickly lost interest. When the robot went back to its old self, the kids treated it like a peer again.

     "The study shows that current technology is very close to being able to produce robots able to develop a special relationship with toddlers," says Movellan. But, he adds, it is not clear yet whether robots can interest older children or adults in the same way.

The effects of rapid travel on the body are actually far more disturbing than we realize. Jet Lag is not a psychological consequence of having to readjust to a different time zone. It is due to changes in the body’s physiological regulatory mechanisms, specifically the hormonal systems, in a different environment.

     Now that we understand what Jet Lag is, we can go some way to overcome it. A great number of the body’s events are scheduled to occur at a certain time of day. Naturally these have to be regulated, and there are two regulatory systems which interact.

    One timing system comes from the evidence of our senses and stomachs, and the periodicity we experience when living in a particular time zone. The other belongs in our internal clocks (the major one of which may be physically located in a part of the brain called the suprachiasmatic nucleus) which, left alone, would tie the body to a 25-hour rhythm. Normally the two timers are in step, and the surroundings tend to regularize the internal clocks to the more convenient 24-hour period.

     If, however, you move the whole body to a time zone which is four hours different, the two clocks will be out of step, like two alarm clocks which are normally set together, but which have been reset a few hours apart. Whereas the two clocks would normally sound their alarms together, now they ring at different times. Similarly, the body can be set for evening while the sun is rising.

     In time the physiological system will reset itself, but it does take time. One easily monitored rhythm is palm sweating. A man flown to a time zone different by 10 hours will take eight days to readjust his palm sweat. Blood pressure, which is also rhythmical, takes four days to readjust.

What can we do about it? It is not feasible to wait four days until the body is used to the new time zone. Fortunately there is a short cut. It relies on two things-the power of the stomach to regulate the timing of other events, and the pharmacological actions of coffee. The basic assumptions are:

Coffee delays the body clock in the morning, and advances it at night. Coffee at mid-afternoon is neutral. Protein in meals stimulates wakefulness, while carbohydrates promote sleep. Putting food into an empty stomach helps synchronize the body clock.

46. What is jet lag associated with?

  A. Psychological change.            B. Physiological change.

  C. Inexperience of rapid travel.       D. Unfamiliar environment.

47. What helps us to adjust to a 24-hour rhythm?

  A. Alarm clock.                   B. Suprachiasmatic nucleus in our brain.

  C. Signals from outside of the body.   D. Our senses and stomachs.

48. What do we know from the fifth paragraph?

  A. A person moving to a different time zone will suffer from high blood pressure.

  B. A person moving to a different time zone will sweat a lot.

  C. Moving to a different time zone will affect both palm sweat and blood pressure.

  D. If the rhythm of blood pressure and palm sweat are not in step, there will be jet lag.

49. What should we do if we want to stay awake?

  A. To take coffee at three o’clock in the afternoon.

  B. To have meals that contain lots of protein.

  C. To have some carbohydrate drinks.

  D. To stop putting food into our stomach.

50. How can we cure jet lag?

   A. To sleep for days.      B. To wait for self-recovery.

   C. To drink tea.           D. To get something to eat.

SECTION B (10 points)

Directions: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.

The worst US economic recession (萧条) in 70 years is forcing senior citizens out of retirement, leaving them fighting for jobs in a weak labor market or risking homelessness.

A study by Experience Works, released on Tuesday, showed 46 percent of the 2,000 low income people over 55 years who participated needed to find work to keep their homes. Nearly half of them had been searching for work for more than a year.

“These people are at the age where they understandably thought their job-searching years were behind them,” said Cynthia Metzler, president and CEO of Experience Works.

“But here they are, many in their 60s, 70s and beyond, desperate to find work so they can keep a roof over their heads and food on the table.”

According to the study, many of the participants had no intention of working past their 60th birthday, but had to change plans after being dismissed or following the death of the partner. Over a third of the participants had retired.

Ninety percent of respondents 76 years and older planned to continue working for the next five years.

Huge medical bills due to a personal illness or that of a spouse(配偶) were also reasons for coming out of retirement, the survey found. The longest and deepest economic slump since the 1930s is making finding a job for the low-income elderly workers a difficult challenge.

The Experience Works study found that 46 percent of the elderly jobseekers were sometimes forced to choose between paying rent, buying food or medication. Almost three-quarters believed their age made it harder to compete for jobs with younger workers.

“This study underscores calls for the need to create policies that remove barriers to employment for older workers and provide additional programs and services specifically aimed at helping older people re-enter the work force or remain working,” said Metzler.
