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 watched or books we've just finished reading，but plain and simple（51）C．
Language is our greatest treasure as a species，and what do we（52）B 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（53）A situations involving children，lovers，and colleagues．
So why are we keen on gossiping？Are we just natural（54）D，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（55）A issues．

But as the groups got bigger and bigger，the amount of time spent in grooming activities also had to be（63）B to maintain its effectiveness．Clearly，a more （64）B 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 （65）C contact．
