The global population is living longer，and getting older，which presents new challenges. “The question becomes：who will take care of everyone? While people will always be the best caregivers for people，there just aren’t enough people. That’s where robotic technology can really make a difference,” says Professor Maja Mataric at the University of Southern California.

Her group is developing robots to work with stroke (中风) patients and elderly people. The research team has found that people react well to a robot gym instructor，and seem to get less frustrated with it than with instructions given on a computer screen. The robot can act as a perfect trainer，with infinite(极大的) patience.

“People say things like ‘I prefer this robot to my husband！Can I take it home?’” according to Professor Mataric. “In fact there’s a really important point here. As we create these care giving technologies，we’re helping not only the people that need the care，but also the people caring for them. We can give them a break，and help them avoid burnout.”

People are going to have to like，and importantly trust robots before they welcome them into their homes，and several groups around the world are working on making it easier to communicate with them.

Much of human communication takes place through body language. Gestures， eye contact , and concepts of personal space are all things that robots are being taught. In learning about how people interact(互动) with machines，researchers are also discovering new roles for robots in our lives. Robots can communicate with humans in ways that other technologies can not.

“If someone finds the robot to be more persuasive and more reliable，that’s going to affect how they interact with it,” says Dr Cynthia Breazeal, director of the Personal Robots Group at the Massachusetts Institute of Technology. “We can now start to think about fields where it’s the social interaction，which is the main means by which a robot helps someone.” Dr Breazeal says that means robots could be used in education，learning，and health care，where social support is important.

1.Professor Maja Mataric mainly focused on robots’ function of ________.

A．teaching 　　 B．exploring

C．making things 　 D．giving care

2.Why can robots be wonderful trainers in the gym?

A．Because they are more clever.

B．Because they give correct instructions.

C．Because they cost less money.

D．Because they are more patient.

3.The underlined word “burnout” in Paragraph 3 probably means “________”．

A．feeling tired 　 B．feeling angry

C．getting hurt 　 D．becoming disappointed

4.The scientists are presently working hard to help robots　　　　 .

A．to use less electricity　　 B．to communicate better

C．to react more quickly　　　 D．to have more functions

Enjoy the challenge of a new term

The new term is finally here, which means, of course, it's time to return to school.

For many students across China, that also means having to leave home for the next several months and move into a school dormitory.

Being away from our family for a long time, however, often leads to homesickness, a feeling that most students have experienced at some point.

A study by the UK's National Union of Students found that up to 70 percent of UK students living away from home experience homesickness within their first few weeks of being away.

But homesickness isn't just a feeling of sadness that happens in our mind; it can also affect us physically.

“You feel homesickness in your stomach—it's an unease in which you feel uncomfortable, nervous, stressed because you're in a place or situation that's not familiar,” Joshua Klapow, a professor of public heath at the University of Alabama, us, told HuffPost.

According to Klapow, the body reacts physically when it's placed in an unknown situation such as being separated from one's familiar surroundings for a long time.

“It's an evolutionary(进化的) thing that makes us protect ourselves from danger when something is unknown," he told the HuffPost.

“When we think about home, we know that the sense of unknown … is not happening there, so we want to return.”

So, how can we overcome these physical reactions?

Ruth Hardy of the Guardian offered advice for students who are feeling the effects of being away from the safety of home.

“Try and establish routines(常规) quickly. This can make your new environment feel more stable and will hopefully make you feel more settled,” she wrote.

Making friends with others who are in your situation is also a great way to feel less homesick, according to Hardy.

The most important thing to remember, however, is that homesickness is completely normal and is nothing to be ashamed of.

And once it's gone, you're free lo enjoy the adventures and challenges of a brand new school year.

1.The study by the UK's National Union of Students is mentioned to　　　 .

A.show how homesickness causes harm to students

B.prove it's common for students to feel homesick

C.introduce some causes of homesickness

D.show how all young people are troubled by homesickness

2.What can we learn about homesickness?

A.It's only a feeling in our mind.

B.It usually disappears after a few weeks.

C.It has a physical influence on our body.

D.It always happens once we visit an unfamiliar place.

3.According to Klapow, why is homesickness helpful to humans?

A.It shows people the importance of their family.

B.It drives people to get used to changes.

C.It encourages people to express their feelings.

D.It keeps people away from possible dangers.

4.How does Hardy suggest people deal with homesickness?

A.Take part in as many activities as possible.

B.Talk about your problems with your friends.

C.Get into a routine as early as possible.

D.Avoid seeing things related to your home life.

Decision-making under Stress

A new review based on a research shows that acute stress affects the way the brain considers the advantages and disadvantages, causing it to focus on pleasure and ignore the possible negative (负面的) consequences of a decision.

The research suggests that stress may change the way people make choices in predictable ways.

“Stress affects how people learn,” says Professor Mara Mather. “People learn better about positive than negative outcomes under stress.”

For example, two recent studies looked at how people learned to connect images(影像) with either rewards or punishments. In one experiment, some of the participants were first stressed by having to give a speech and do difficult math problems in front of an audience; in the other, some were stressed by having to keep their hands in ice water. In both cases, the stressed participants remembered the rewarded material more accurately and the punished material less accurately than those who hadn’t gone through the stress.

This phenomenon is likely not surprising to anyone who has tried to resist eating cookies or smoking a cigarette while under stress –at those moments, only the pleasure associated with such activities comes to mind. But the findings further suggest that stress may bring about a double effect. Not only are rewarding experiences remembered better, but negative consequences are also easily recalled.

The research also found that stress appears to affect decision-making differently in men and women. While both men and women tend to focus on rewards and less on consequences under stress, their responses to risk turn out to be different.

Men who had been stressed by the cold-water task tended to take more risks in the experiment while women responded in the opposite way. In stressful situations in which risk-taking can pay off big, men may tend to do better, when caution weighs more, however, women will win.

This tendency to slow down and become more cautious when decisions are risky might also help explain why women are less likely to become addicted than men: they may more often avoid making the risky choices that eventually harden into addiction.

1.We can learn from the passage that people under pressure tend to ______.

A.keep rewards better in their memory

B.recall consequences more effortlessly

C.make risky decisions more frequently

D.learn a subject more effectively

2.According to the research, stress affects people most probably in their ______.

A.ways of making choices B.preference for pleasure

C.tolerance of punishments D.responses to suggestions

3.The research has proved that in a stressful situation, ______.

A.women find it easier to fall into certain habits

B.men have a greater tendency to slow down

C.women focus more on outcomes

D.men are more likely to take risks

If maths is the language of the universe, bees may have just uttered their first words. New research suggests these busybodies of the insect world are capable of addition and subtraction (减法) — using colors in the place of plus and minus symbols.

In the animal kingdom, the ability to count — or at least distinguish between differing quantities — isn’t unusual: It has been seen in frogs, spiders, and even fish. But solving equations (方程式) using symbols is rare, so far only achieved by famously brainy animals such as chimpanzees and African grey parrots.

Building on previous research that says the social insects can count to four and understand the concept of zero, researchers wanted to test the limits of what their tiny brains can do.

Scientists trained 14 bees to link the colors blue and yellow to addition and subtraction, respectively. They placed the bees at the entrance of a Y-shaped maze (迷宫), where they were shown several shapes in either yellow or blue. If the shapes were blue, bees got a reward if they went to the end of the maze with one more blue shape (the other end had one less blue shape); if the shapes were yellow, they got a reward if they went to the end of the maze with one less yellow shape.

The testing worked the same way: Bees that “subtracted” one shape when they saw yellow, or “added” one shape when they saw blue were considered to have aced the test. The bees got the right answer 63% to 72% of the time, depending on the type of equation and the direction of the right answer — much better than random guesses would allow—the researchers report today in Science Advances.

Though the results came from just 14 bees, researchers say the advance is exciting. If a brain about 20,000 times smaller than ours can perform maths using symbols, it could pave the way to novel approaches in artificial intelligence (AI) and machine learning. Just don’t ask the bees to do your homework anytime soon.

1.Why do the scientists conduct the research?

A.To teach them maths. B.To test the power of tiny brains.

C.To explain the meaning of colors. D.To get access to machine learning.

2.What does the underlined word “aced” in Paragraph 5 probably mean?

A.Given up. B.Entered for.

C.Got through. D.Checked over.

3.What might the research make contributions to?

A.Language acquisition. B.Arithmetic learning.

C.Protection of animals. D.Development of AI.

4.What can be the best title for the text?

A.Bees “Like” Counting

B.Bees “Tell” Colors Apart

C.Bees “Perform” Maths Using Shapes

D.Bees “Get” Addition and Subtraction
