Man is Different from Animals 

      Man has a big brain. He can think, learn and speak. Scientists once thought that man is different from 

animals because he can think and learn. They know now that dogs, monkeys, birds can learn, too. They are 

beginning to understand that man is different from animals because he can speak. Animals cannot speak. They

make noise when they are afraid or angry, unhappy. Apes (猿) can understand more quickly than people. One 

or two of them have learnt a few words. But they cannot join words to make sentences. They cannot think like 

us because they have no language. Language is a wonderful thing. Man has been able to build a modern world 

because he has language. A child can speak his own language very well when he is four or five, but no animal 

learns to speak. How do children learn? Scientists do not really know. What happens inside (在……的里面) 

our body when we speak? They do not know. They only know that man can speak because he has a brain.

( ) 1. Man can think, learn and speak because he has a big brain. 

( ) 2. Man is different from animals because he can think and learn. 

( ) 3. The difference between man and animals is that man can speak. 

( ) 4. Man can speak his own language very well even when he is four or five.   

( ) 5. How children learn to speak is still difficult to understand.

      As a boy growing up on a farm near the Caribbean coast of Colombia(哥伦比亚), Alvaro

Cogollo loved both plants and vallenato, the traditional music of the region.As a biology student

in the 1970s, Cogollo traveled around the country to document its rich botanical heritage and,

informally, studied the music that tells an important story of Colombia.

     "We were colonized by the Spanish; later, Africans were brought as slaves to exploit gold

mines; and the native peoples were already here," he says."That is what authentic vallenato

represents with its three instruments: the accordion(手风琴), from a European origin; la caja drum,

which is of African origin; and la guacharaca, a beating instrument made from a palm tree, which is

from native American origin."

     Over the course of his nearly four-decade career, Cogollo has discovered more than 150 new

species of plants, 17 of which bear his name.Although Cogollo never earned a PhD, his colleagues

say he's made invaluable contributions to knowledge of Colombia's plant at a time when deforestation

(砍伐森林) is a big threat to the country' s biodiversity.Governments have focused on trying to move

 the country out of poverty and conflict through exploiting its natural resources, not through scientific

resource development.But Cogollo sees things a different way.By educating the public about alternative

uses for the land, and researching plants' potential uses-including as medicines, foods, and bio-fuels-

Golombia could improve its economy and quality of life without neglecting conservation, Cogollo says.

     Cogollo's other major achievement has been the transformation of a neglected botanical garden in a

Medellm neighborhood into a well-known center for research, environmental education, and community

gatherings.What had been a club for wealthy orchid enthusiasts now offers free admission and attracts

rich and poor alike.The success of the botanical garden has in turn contributed to the transformation

of Medellm.Once seriously damaged, by violent wars between armed groups, the city has had some

improvements that include better public safety, tougher pollution controls and the creation of green

spaces.

     What Cogollo has focused his latest efforts on is teaching Colombians from all social classes and

backgrounds about the importance of biodiversity and conservation through a shared musical heritage.

"The fact that Alvaro's been able to give talks to audiences filled with all kinds of people is very

important, and that's what happened in Medellm the first time he talked about vallenato music,"

Dr.Forcro says."People sitting there had no idea of environmental conservation, and then they did."

1. What's the main feature of vallenato music?
