Until recently, scientists and authors were in absolute disagreement over the point of crying. In King Henry VI, Shakespeare wrote,”…, to weep is to make less the depth of grief”, and the American writer Lemony Snicket said “unless you have been very, very lucky, you know that a good, long session of weeping can often make you feel better, even if your circumstances have not changed one bit”.

Charles Darwin, on the other hand, thought that shedding tears (the act of crying) was merely a useless side effect of the way that the muscles around the eye worked. For him, those muscles had to contract（收缩）from time to time so that they didn’t overflow with blood; the expulsion of tears was simply an unintended consequence of that evolved physiological（生理学的）process. He did acknowledge that crying could help young infants attract the attention of their parents, though.

We now know that crying—at least, the sort that adults do—is a complex physiological response to some kind of emotional stimulus. The most noticeable feature is of course the shedding of tears, but it also includes changes in facial expressions and breathing patterns.

From a scientific perspective, crying is different from shedding the kind of tears like when you accidentally rub your eyes after eating spicy foods. Even the tears themselves are different. In 1981, Minnesota psychiatrist William H Frey II discovered that tears flowing due to sad movies had more protein in them than those that flowed in response to some freshly chopped onions.

If you shed tears of laughter when seeing a funny comedy show or you're moved to tears when listening to a bridegroom’s wedding vows to his bride, you may know that emotional tears aren't limited to feelings of deep sadness. While all of us are familiar with the feelings that are associated with crying, whether for joy or sorrow, we know little about why we do it as adults-but there are plenty of ideas.

One idea is that adult crying isn't actually all that different from the sort that babies do, at least when it comes to its social nature. In other words, perhaps weeping is a literal cry for attention, a means of soliciting support and help from our friends when we need it the most. It’s a way of communicating our inner emotional state at a time when we may not be able to express it clearly.

While this may explain some forms of crying, many researchers have found that adults often cry when they’re completely alone. Another possibility is that crying might serve as a means of “secondary appraisal,” helping people to realize just how upset they are, a way of just how upset they are and helping them understand their own feelings.

Another idea is that crying provides relief from stressful situations. The idea is consistent not only with the words of Shakespeare, but also with the words of Roman Poet Ovid, who wrote, “It is some relief to weep; grief is satisfied and carried off by tears.” The Greek Philosopher Aristotle also wrote that crying “cleanses the mind”. In a 1986 study of popular US magazines and newspapers, one psychologist found that 94% of articles about crying suggested that it helped to relieve psychological tension.

Indeed, a 2008 study of nearly 4,300 young adults from 30 countries found that most reported improvements in both their mental and physical well-being after a short period of crying, but not all. Some reported no change after a crying session, and some even said that they felt worse afterwards.

The difference seems to lie in the social context: if a person felt embarrassed about crying in public, for example, they might feel less resolved than if they cried alone or with a friend. The study also found that when people tried to suppress or hide their crying, they ended up feeling less relieved afterwards.

So the notion of having “a good cry” is not without merit. In the end, adults might just cry for the same reason as human infants: to seek help from their friends and family.

1.According to Darwin, shedding tears was ________.

A. the same thing as crying

B. aimed at attracting other’s attention

C. nothing but a physiological process

D. an effective way to get rid of negative emotions

Scientists are using robots to study the health of waters in and around Venice，Italy．The robots are designed to act like fish，other underwater creatures and plants．The scientists are working with several universities and research centers as part of a group called subCULTron．The European Union gives money to the project as part of its Horizon 2020 program whose aim is to take great ideas from the lab to the market and support science and innovation(创新)in Europe．The scientists want to use the artificial intelligence of the robots to help humans understand what is happening under the water of the Venice lagoon(潟湖)．

SubCULTron．a collective artificial intelligence project，plans to create the biggest shoal (鱼群)of robot fish in the world．The project’s aim is to improve knowledge of the seabed and try to turn human abilities into hi-tech items．

Alexandre Campo，a computer scientist，says the scientists have looked at the way animals learn to work in groups to understand how robots can learn to work together．The subCULTron project wants its robots to learn to work together so they can watch out for changes and new problems in the water．

One problem the researchers had in the beginning was how the robots would communicate with each other. Wi-Fi and GPS equipment don’t work underwater．Instead，the robots can use sonar(声呐)and an electric field．

Another problem was charging batteries．The robots come up to the water’s surface and stay near a boat or a power station to charge without any electrical cables．Besides，how to be waterproof, especially for some key pads of the robots，was really tough．Fortunately, a special mixture has been created to be pinned on the robot，which successfully stands the test of water．

The health state of the lagoon is pretty good．There are no industrial polluters，and the city now has a modern sewer(污水管) system．It’s not like before when all the waste flushed directly into the water．The robots in Venice will continue their work until 2019. The subCULTron project hopes they develop into “an artificial society underneath the water surface” that serves “a human society above the water”．

1.What can we learn about the project in Paragraph l?

A. Its researchers are all from universities．

B. The European Union has financially supported it．

C. It uses robots to clean the waters in and around Venice．

D. It is aimed to support science and innovation worldwide．

2.What can we infer according to Alexandre Campo?

A. Scientists have got an idea for robots from the animals．

B. The robots are working separately to perform their tasks．

C. SubCULTron is to turn human abilities into hi-tech items．

D. The health state of the lagoon has greatly improved recently．

3.The underlined word “they” in the last paragraph probably refers to“__________”．

A. scientists　　 B. animals

C. robots　　 D. humans
