Whistles and chirps are like the sounds that many birds make.Now scientists have translated some of their squirrel-speak. Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls.The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture their reponses.Some squirrels lifted their heads up and became.Alert .Creatures that were more frightened simply ran for their lives and dived into caves. "In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger.' " Hare told.Discovery News. Hare and some other researchers believe such sounds arc part of an advanced language that develops just as all other communication systems. Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behaviour, thus increasingly the caller's social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls. In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too.According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms. While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests . Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide "hope that humans will gain a greater appreciation and...

input:  Now, answer this question: Read the following article and answer the question. Article: What would we do without humour? How would we enjoy speaking with others if we did not use humour to invite a smile or a laugh? And how would we manage in times when we feel sad and lonely?     Using humour we lighten up each day, and we find common ground with others. We build healthy relationships with others by knowing what to say and what to do. When our use of humour is successful, we build trust and cooperation. We discover that we are not alone, we learn to accept our mistakes, and we look for the good in others and in ourselves. Most importantly, we create common ground, as humour is an essential skill needed to communicate well with others. A few well-chosen words get the attention of others and make a serious point without their getting defensive  . Whether we prefer to be the centre of attention or to be shy and quiet, humour can be adjusted   to suit our personality.      However, when we lose our sense of humour, we often get critical or defensive, and we blame others or ourselves for what was said, and how it was said.      To ensure that our humour is welcomed by others, we need to combine our humour with speaking clearly and listening effectively.     Have you ever noticed that successful individuals often use self-depreciating humour to humble   themselves, without putting themselves down? These individuals understand that every person has strengths and weaknesses and that self-depreciating humour invites others to feel more confident and equal. In this way, humour is the shortest distance between two people.      Humour is the spice of life, as it brings happiness, numbs pain and it makes us speak and listen well. Question: Successful individuals often use self-depreciating humour to humble themselves, because they think   _  . Answer:

Energy released from Wenchuan earthquake would be 30 times of that from Ya'an quake, according to Zhang Xiaonan, an expert with China's Geophysical Union. Dai Junwu with Harbin-based seismological bureau expects the death toll at less than 1,000, and economic losses from the quake could reach up to 100 billion yuan. Police and expert teams have already rushed for rescue in the quick stricken areas, and the State Council has banned unauthorized rescue efforts and individual vehicles from going to the quake zone to avoid congestion .
