【推荐1】It is proved that a young scientist named Will Smith has invented a kind of advanced and intelligent robot. The small robot may help children who are____from a long-term illness in hospital or at home.

Whoever has had a long-term illness knows that recovering at home can be          __, as everyone canˈt keep them____, especially when their family go out to work. These children may feel_____from their friends and classmates, which can be particularly ____ of children. They may feel ____. Now these children may have a high-tech friend to help____the sense of loneliness. The friend is a robot, which takes their_____at school. Through the robot, the children can ___ teachers and classmates. They___ participate in class from ___ they are recovering. Mr Smith, the inventor____how it works. He says the child uses a tablet or phone to start the robot. Then the ____ uses the same device to control the robotˈs movements at school; the robot becomes the ears and ___ of the child, so that he or she can take part in classroom activities— ____ he or she is at home or from a hospital bed.

【推荐2】Microsoft Corp founder Bill Gates caught people’s eye in a recent interview, when he suggested that robots should be taxed in, order to help humans keep their jobs. Gates is only one of many people in the tech world who have worried about automation and its ________ to workers.

It’s easy to see why the tech world is ________. The rise of machine learning has increased the fear that ________ humans could simply become out of date--________, 3.5 million American truck drivers might soon find their jobs threatened by driverless trucks. Though in the past, technology usually complemented workers ________ replacing them, there’s no law of nature saying the technology of the future will work the same. A few economists even claim that cheap automation has already ________ income from workers to company owners.

Another ________ is that even if the mass of humanity ultimately does find new ways to add value by complementing new technology—to“race with the machines,”as economist Erik Brynjofsson puts it—this transition could take a long time and hurt a lot of people. As Bloomberg View’s Tyler Cowen has noted, wages in Britain fell for four decades at the start of the Industrial Revolution. More ________, we’ve seen very slow and painful adjustment to the impact of globalization. If the machine learning revolution hurts workers for 40 years before ultimately helping them, it might be worth it to ________ that revolution and give them time to adjust.

The main argument against taxing the robots is that it might hold back ________. Growth in rich   countries has slowed markedly in the past decade, suggesting that it’s getting harder and harder to find new ways of doing things. Stagnating productivity, combined with falling business investment, suggests that ________ of new technology is currently too slow rather than too fast—the biggest problem right now isn’t too many robots, it’s too few. Taxing new technology, however it’s done, could make that slowdown worse.

The problem with Gate’s basic proposal is that it’s very hard to tell the difference between new technology that ________ humans and new technology that replaces them. This is especially true over the long term. Power looms（织布机）replaced human weavers back in the Industrial Revolution. ________, people eventually became more productive, by learning to operate those looms. If taxes had slowed the development of power looms, the eventual improvements would have come later.

This is a powerful argument ________ the taxation of automation. Gates is right to say that we should start thinking ahead of time about how to use policy to mitigate（缓和）the unintended consequences of automation. But given the importance of sustaining innovation, we should look at ________ policies.

【推荐1】You can actually catch a good mood or a bad mood from your friends, according to a recent study in the journal Royal Society Open Science. But that shouldn't stop you from _______ with pals who are down in the dumps, say the study authors. _______, the effect isn't large enough to push you into depression.

The new study adds to a growing body of research suggesting that happiness and sadness—as well as lifestyle and behavioral factors like smoking, drinking, obesity, fitness habits and even the ability to concentrate—can _______ across social networks, both online and in real life. But while many _______ studies have only looked at friendship data at one point in time, this is one of the few that measured social and mood changes over time.

The new research involved groups of junior-high and high-school students who took part in _______ screenings(筛查) and answered questions about their best friends, many of whom were also enrolled in the study. In total, 2,194 students were included in the _______, which used a mathematical model to look for connections among friend networks.

Overall, kids whose friends suffered from bad moods were more _______ to report bad moods themselves and they were less likely to have improved when they were screened again six months to a year later. When people had more happy friends, _______, their moods were more likely to improve over time.

Some symptoms related to depression-like helplessness, tiredness and loss of interest-also seemed to follow this _______, which scientists call “social contagion.” But this isn't something that people need to ________, says lead author Robert Eyre, a doctoral student at the University of Warwick. Rather, it's just a “________ empathetic (感同身受的) response that we're all familiar with, and something we recognize by common sense,” he says. In other words, when a friend is going through a rough period, it makes sense that you'll feel some of their ________, and it's certainly not a reason to stay away.

The study also found that having friends who were clinically depressed did not ________ participants' risk of becoming depressed themselves. “Your friends do not put you at risk of illness,” says Eyre, “so a good course of action is simply to ________ them.” To boost both of your moods, he suggests doing things together that you both ________ and taking other friends along to further spread those good feelings, too.”

【推荐3】Research has shown that two-thirds of human conversation is taken up not with discussion of the cultural or political problems of the day, not heated debates about films we’ve just seen or books we’ve just finished reading, but plain and simple _________.

Language is our greatest treasure as a species (物种，品种), and what do we _________ do with it? We gossip about others’ behavior and private lives, such as who’s doing what with whom, who’s in and who’s out — and why; how to deal with difficult _________ situations involving children, lovers and colleagues.

So why are we keen on gossiping? Are we just natural _________of both time and words? Or do we talk a lot about nothing in particular simply to avoid facing up to the really important issues of life? It’s not the case according to Professor Robin Dunbar. In fact, in his latest book, Grooming, Gossip and the Evolution of Language, the psychologist says gossip is one of these really _________ issues.

Dunbar _________the traditional view that language was developed by the men at the early stage of social development in order to organize their manly hunting activities more effectively, or even to promote the exchange of poetic stories about their origins and the supernatural (超自然现象). Instead he suggests that language evolved among women. We don’t spend two-thirds of our time gossiping just because we can talk, argues Dunbar – _________ , he goes on to say, language evolved specifically to allow us to gossip.

Dunbar arrived at his cheery theory by studying the _________of the higher primates (灵长类动物) like monkeys. By means of grooming — cleaning the fur by brushing it, monkeys form groups with other individuals on whom they can rely for support in the event of some kind of conflict within the group or _________ from outside it.

As we human beings evolve from a particular branch of the primate family, Dunbar __________ that at one time in our history we did much the same. Grouping together made sense because the bigger the group, the greater the __________ it provided; on the other hand, the bigger the group, the greater the stresses of living close to others. Grooming helped to __________the pressure and calm everybody down.

But as the groups got bigger and bigger, the amount of time spent in grooming activities also had to be __________ to maintain its effectiveness. Clearly, a more __________ kind of grooming was needed, and thus language evolved as a kind of vocal (有声的) grooming which allowed humans to develop relationship with ever-larger groups by exchanging information over a wider network of individuals than would be possible by one-to-one __________ contact.
