Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation—their young trees?

Professor Simard , forest ecologist( 生态学家) from the University of British Columbia, explains how trees are much more complex（复杂）than most of us ever imagined. Although Charles Darwin（达尔文） thought that trees are competing for survival of the fittest, Simard and her team have made a new discovery and showed just how wrong he was. In fact,the opposite is true: trees survive through their group work and support, passing around necessary nutrition (营养) like Nitrogen (氮) and carbon "depending on who needs it".

Nitrogen and carbon are shared through miles of underground fungi (真菌) networks, This makes sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.

Simard talks about "mother trees", These are usually the largest and oldest plants on which all other trees depend. These “Mother Trees” are connected to all the other trees in the forest by this network of fungi, and may manage the resources of the whole trees and plants in the forest. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down "Mother Trees" without paying attention to these highly complex "tree societies" or the networks on which they feed, we are reducing the chances to save the whole forest.

"We didn't take any notice of it" Simard says sadly. "Mother trees move nutrition into the young trees before dying, but we never give them chance." If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

A. compete for survival B. protect their own wealth

2."Mother trees" are extremely important because they________.

A. look the largest in size in the forest

B. pass on nutrition to young trees

3.The underlined word "it" in the last paragraph refers to__________.

A. how "tree societies" work B. how trees grow old

C. how forestry industry develops D. how young trees survive

4.What would be the best title for the passage?
