20.Would it surprise you to learn that,like animals,trees communicate with each other and pass on their wealth to the next generation?UBC Professor Simard explains how trees are much more complex than most of us ever imagined.Although Charles Darwin thought that trees are competing for survival of the fittest,Simard shows just how wrong he was.In fact,the opposite is true:trees survive through their co-operation and support,passing around necessary nutrition"depending on who needs it".
Nitrogen(氮) and carbon are shared through miles of underground fungi(真菌)networks,making 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",usually the largest and oldest plants on which all other trees depend.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"with no awareness of these highly complex"tree societies"or the networks on which they feed,we are reducing the chances of survival for the entire forest.
"We didn't take any notice of it."Simard says sadly."Dying 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.

分析 文章介绍树和树之间不是你死我活的竞争关系,它们之间是相互依赖的,快要死的树会将自己的营养传给小树让它们更好的成长,人们如果知道这些现象,就可以更好的保护这些树.
解答 32.D.标题确定题:根据全文内容,可知文章介绍树和树之间不是你死我活的竞争关系,它们之间是相互依赖的,快要死的树会将自己的营养传给小树让它们更好的成长,从第一段的句子:Would it surprise you to learn that,like animals,trees communicate with each other and pass on their wealth to the next generation?可知作者想要表达的是树要比我们想象的要更加令人惊叹,所以选D.
33.B.细节理解题.根据第二段In fact,the opposite is true:trees survive through their co-operation and support,passing around necessary nutrition"depending on who needs it可知在西马德看来,树相互依赖;故选B.
34.D.推理判断题.根据第三段When humans cut down"mother trees"with no awareness of these highly complex"tree societies"or the networks on which they feed,we are reducing the chances of survival for the entire forest可知"母树"影响整个森林的生存;故选D.
35.A.词义猜测题:it出现在文章最后一段We didn't take any notice of it."Simard says sadly."Dying trees move nutrition into the young trees before dying,but we never give them chance:实际上it指代的是第四段提到的内容,人们砍倒快死的mother trees是不知道树的社会的依存关系,可知it指的是"树的社会"是怎么运作的,所以选A
