    Engineers in Upstate New York have invented a folded paper device that looks like a decorated art project. But don't be fooled. This is actually a paper-based battery. No, it doesn't look like any of those metal batteries running flashlights or smartphones. In these systems, the battery can be printed on a page. The battery's power consists of living bacteria.

    Paper electronics are simple to make and inexpensive, notes study leader Seokheun Choi, an engineer at Binghamton University. They need no electrical outlet to recharge. They just need more bacteria, which can be found everywhere — including dirty water.

"Most batteries use chemicals to generate electricity. Substituting bacteria can be an advantage," Choi says. "They are cheap and self-repairing." What paper-based batteries won't do is generate much power. They do, however create enough to run small devices in faraway or dangerous places — such as a battlefield. They might also find use in medicine. For instance, they might power tiny sensors, such as the types used to measure blood sugar.

This invention is based on an observation made more than a century ago — that microbes (微生物) produce electricity as they digest food. Scientists refer to the bio-batteries based on this principle as microbial fuel cells. A fuel cell generates electricity like a regular battery. But a regular battery stops producing electricity when its inner chemical reactions stop. A fuel cell uses fuel that can be refilled. In this case, bacteria serve as the fuel. By refilling more microbes, as needed, scientists can keep these fuel cells running.

    Lab tests have shown that the new battery can produce a current. Now, Choi and his team are looking at ways to increase the power. They're studying different shapes and materials for the anode and cathode (正负极). They're also looking for the best ways to combine batteries for more power. The beauty of the paper devices is that you can simply fold them to connect them. And they surely will be a trend in the near future.

What's wrong with Jane?

阅读下面短文，从短文后各题所给四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项。

    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 watched or books we've just finished reading, but plain and simple 1.

    Language is our greatest treasure as a species, and what do we 2 do with it? We gossip. About others' behaviour 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 3 situations involving children, lovers, and colleagues.

    So why are we keen on gossiping? Are we just natural 4, 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 vital 5.

    Dunbar 6 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. 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—7, he goes on to say, language evolved specifically to allow us to gossip.

    Dunbar arrived at his cheery theory by studying the 8 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 9 from outside it.

    As we human beings evolve from a particular branch of the primate family, Dunbar 10 that at one time in our history we did much the same. Grouping together made sense because the bigger the group, the greater the 11 it provided; on the other hand, the bigger the group, the greater the stresses of living close to others. Grooming helped to 12 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 13 to maintain its effectiveness. Clearly, a more 14 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 15 contact.

    Today I was going home by bike where a little dog ran to me. I stopped in time avoid hitting the dog. Luckily, it was not injuring, but lay on the ground. I came nearer and touched its side gently. It jumped to its foot quickly and stared at me in a friendly way. Seeing nothing seriously, I was about to leave, but the dog stops me by biting my trousers. So I wanted to adopt to the dog but it was unfair for its master. Just then, the woman came, saying that the dog was his and that I could take it away. Thus I got a lovely pet and I was very grateful for this kind woman.
