　　Simon and Garfunkel once famously sang “I am a rock, I am an island”．It's a great song, but is simply isn't true! For whatever reason, we all seem afraid to ask for help, even from those closest to us, regardless of whether we need or deserve it．There's something in our society than seems to dictate that we have to do it all by ourselves-either the views that we'll be seen as weak, or just simply pride．

　　This, however, doesn't seem to be true of successful people．They haven't bought into the fallacy that asking for help is wrong．They know the truth that great things are achieved when people cooperate．

　　We all have different skills, knowledge and experiences．Each person you know is a whole new set of untapped(未使用的)reference material and expertise．So if you want to get hold of it and use it, all you have to do is ask them．People are rarely unwilling to assist-it's in our nature to be part of communities．

　　A good example I sometimes use in seminars is to pick a delegate at random and ask him how many people he knows in total．The usual answer is somewhere between 200 and 500．For the sake of this illustration, let's select the lower figure and call it 200．Then I ask the person how many people each of those people knows．On the assumption that they have similar-sized corc; es．they almost certainly know at least 200 people each．On this basis, the people within one degree of separation(1度分割理论：朋友的朋友形成一个小世界)for a person who knows 200 people comes to 40, 000-can you imagine the size of that experience and knowledge pool?

　　Looking as it this way, giving your friends, family and colleagues the opportunity to help you open your resource bank to thousands of people．That's a whole army of potential volunteers all waiting to be praised!

　　So, next time you need help, don't suffer in silence．Pick up the phone or mention it to a friend．You'll be pleasantly amazed at what you can achieve together．

　　It is the sort of out-of-this-world phenomenon that might have got E．T．himself jumping for ioy (if only his legs had been long enough)．

　　Astronomers bare received three mysterious radio signals from outer space．

　　They picked them up while using a radio telascopc stationed in Puerto Rico to probe deep into the universe．

　　Each signal lasted about one minute and was recorded on the frequency which scientists believe aliens would be most likely to use, namely SHGb02＋I4a (since you ask, this is the frequency at wbich hydrogen readily takes in and gives out energy．) According to New．Scientist magazine, the signal originates from a point her ween the Pi-es and Aries constellations (双鱼座和白羊座) where there is no obvious star or planetary system within 1,000 light years．

　　What is sending tbe signals is unknown, hut scientists working on the Search for Exlraterrestrial Intelligence project believe it could finally prove there is life “out there”．

　　”We are looking for something that screams out ‘artificial'“ said Eric Korpela, a researcher from the University of California, Berkeley．

　　”This just doesn't do that bot it could be because it is distant．”

　　Other scientists are not so sure it will point the way to alien life but they have ruled out a scientific joke．They believe it may be an unknown astronomical phenomenon or even a strange thing of the telescope itself．

　　”If they can see the signal four, five or six times it really begins to get exciting,” said Jocelyn Bell Burnell, from the University of Bath．
