优翼小帮手同步口算系列答案Communications technologies are far from equal when it comes to conveying the truth．The first study to compare honesty across a range of communication media has found that people are twice as likely to tell lies in phone conversations as they are in emails．The fact that emails are automatically recorded—and can come back to puzzle you---appears to be the key to the finding．
Jeff Hancock of Cornell University in Ithaca, New York, asked 30 students to keep a communications diary for a week．In it they noted the number of conversations or email exchanges they had lasting more than 10 minutes, and confessed to how many lies they told．Hancock then worked out the number of lies per conversation for each medium．He found that lies made up 14 per cent of emails, 21 percent of instant messages, 27 per cent of face-to-face interactions and an astonishing 37 percent of phone calls．
His results to be presented at the conference on human-computer interaction in Vienna, Austria, in April, have surprised psychologists．Some expected emailers to be the biggest liars, reasoning that because deception makes people uncomfortable, the indirect contact of emailing would make it easier to lie．Others expected people to lie more in face-to-face exchanges because we are most practiced at that form of communication．
But Hancock says it is also crucial whether a conversation is being recorded and could be reread, and whether it occurs in real time．People appear to be afraid to lie when they know the communication could later be used to hold them to account, he says．This is why fewer lies appear in email than on the phone．
People are also more likely to lie in real time---in an instant message or phone call, say---than if they have time to think of a response, says Hancock．He found many lies are spontaneous（脱口而出） responses to an unexpected demand, such as: “Do you like my dress?”
Hancock hopes his research will help companies work out the best ways for their employees to communicate．For instance, the phone might be the best medium for sales where employees are encouraged to stretch the truth．But, given his result, work assessment where honesty is a priority, might be best done using email．

Not long ago the movie 2012 came into screen. The people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and constructions representing human civilization being destroyed and even swallowed by disaster. Luckily, they are just the director’s imagination, but the present situation is not heading a positive direction, either.
Take my own experience in Alaska as an example. Once I took a trip to the glacier. Along the way there stood signposts marking the snow lines of different years. They started from the foot of the mountain, but it was at the top when I finally saw melting glaciers(融化的冰川). My heart ached seeing the beautiful blue ice melting at every second.
Sad but true, they are the effects of global warming and the result of our human impact. Furthermore, each year the rising sea level will kill 56 million people, and that's about the population of the en tire Italy. According to studies, if the temperature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water.
Our fortune is in our own hands. It depends on us to shape our future, to reduce future human impact and find ways to form a peaceful relationship with our environment. Therefore, it's time for actions to be taken right now. Contribute a little to energy saving by using more efficient light bulbs and less hot water. Let recycle become our habit by thinking twice before throwing something away. Let us take public transportation as our first choice when going to a certain place. It might cost more time for now, but it' s to the benefit of a permanent future. Take care of every tree and grass around us by watering them or simply just avoid destroying them．
In a word, small drops of water make a big ocean. The earth does not belong to us. On the contrary, we belong to the earth. Please bear in mind that the earth is our home. It is our responsibility to build a brighter and better future of our planet and prevent what happened in the movie 2012 from becoming reality．
