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 arc 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.

D. know more about the complex “tree societies”
3.The underlined word “it” in the last paragraph refers to .

D. how young trees survive
4.What would be the best title for the passage?
A. Old Trees Communicate Like Humans
B. Young Trees Are In Need Of Protection
C. Trees Are More Awesome Thart You Think
D. Trees Contribute To Our Society
1.C
2.B
3.A
4.C
【解析】文章大意:本文主要讲述了森立的树木会通过“tree societies”把自己的财富交给下一代。并详细说明了这一发现的具体内容。
1.推理题。根据本句Although Charles Darwin thought that trees arc competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: 可知达尔文认为树是相互竞争以获得生存。但是Simard的实验发现达尔文是错误的。实际上:与达尔文的理论相反的观点是正确的。也就是说树不是竞争生存,而是考相互合作,相互依靠生存下来的。故C正确。
2.推理题。根据文章第四段Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend.可知“mother trees”通常都是其他的树依赖的大树,它承担这向小树输送养料的作用。ACD三项都是片面的理解。故B正确。
3.推理题。根据第四段最后三行和最后一段第一行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.”当人们意识不到这种复杂的“tree societies”情况下砍倒了mother trees,我们就减少了整个森林幸存的机会。最后一段第一句中的it就是指complex “tree societies”。故A正确。
4.主旨大意题。根据文章主题段第一段Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?可知树和动物一样,能够把自己的财富交个下一代。这比人们原来的看法完全不一样,树比我们认为地更聪明。故C正确。

A famous doctor once received a little child who was badly ill. Thanks to his skill and care, his young patient got well and was soon able to get up and run about again.
The child’s mother was very much obliged to the doctor, and she called on him to thank him for what he had done for her child. “Doctor,” she said, “you have saved my little son. I don’t know how to thank you enough. I feel that money alone cannot repay you, so I have made this little purse with my own hands, as a sign of my gratitude. I hope you will accept it.” The doctor stood up and said coldly, “Madam, a little present like that is very nice between friends, but a doctor needs to be paid properly for what he has done.” The lady was so surprised and hurt so much that she could not reply for a moment. Then she said quietly, “Perhaps you will tell me how much your fee is?”
“Fifty pounds”, he answered.

The works of Shakespeare and Wordsworth are “rocket?boosters” to the brain and better than the other self?help books,researchers will say this week.
Scientists,psychologists and the English experts at Liverpool University have found that reading the works of Shakespeare and other classical writers has a beneficial effect on the mind,catches the reader’s attention and triggers moments of self?reflection.Using scanners,they monitored the brain activity of volunteers as they read the works by William Shakespeare,William Wordsworth,T.S Eliot and other classical writers.
They then “translated” the texts into more “straightforward”,modern language and again monitored the readers’ brains as they read the words.Scans showed that the more “challenging” articles and poetry set off far more electrical activity in the brain than the modern versions.Scientists were able to study the brain activity as it responded to each word and record how it “lit up” as the readers came across unusual words,surprising phrases or difficult sentence structures.This “lighting up” of the mind lasts longer than the initial electrical spark,shifting the brain to a higher speed,encouraging further reading.
The research also found that reading poetry,in particular,increases the activities in the right side of the brain,an area concerned with “autobiographical memory”,helping readers to reflect on their own experiences in light of what they have read.The experts said this meant the classics were more useful than self?help books.
Philip Davis,an English professor who has worked on the study with the university,will tell a conference this week:“Serious literature acts like a rocket?booster (火箭助推器) to the brain.”
“The research shows the power of classical literature to shift mental pathways,to create new thoughts,shapes and connections in the young and the old alike.”
1.The author mentioned Shakespeare and Wordsworth in Paragraph One to________.
A.show their great achievements
B.attract our interest in literature

A.help deal with some physical problems
B.benefit our mind and thinking
C.improve our reading skills
D.help learn more about history
3.The scientists and experts did the experiment by________.
A.scanning the readers’ brain activities
B.reading works of different writers
C.lighting up the activities of the brains
D.investigating the habits of the readers
4.We can learn from Paragraph 4 that reading poetry________.
A.is concerned with the right side of the brain
B.has the same effects as reading self?help books
C.helps you forget the things in the past
D.makes you more serious and objective
5.What might be the author’s purpose in writing the text?
A.To introduce some great writers in England.
B.To present a study on brain activities.
