羊的习性 Most people think sheep are stupid, friendly and harmless animals. The sheep are good for two things, being eaten and producing wool. The truth is that sheep are far smarter than we know. They build up friendships and stick up for one another in fights. A 2001 study done by Keith Kendrick, who is now at the University of Electronic Science and Technology in China, found that sheep can remember at least 50 personal faces for more than 2 years. That is longer than many people. “Sheep showed clear signs of being good at telling the differences，” says Kendrick. The team also found that sheep can separate expressions and prefer a smile to a frown(皱眉). At the time Kendrick told BBC News，“The sheep's brain is organized. They must have some kinds of reaction (反应) to what they see in the world.” Sheep also have complex social structures(结构). Over twenty years ago, researchers from the University of California observed for three years and discovered that they set up friendships and looked out for one another in times of need. “They can form long term relationships... they help weaker friends and support each other in fights，” says the 1993 study. They say that sheep are able to experience many feelings, from fear to anger, and from sadness to happiness. 1. According to the passage, the sheep offer people __________.
