Question

【題目】根據短文內容，選擇正確答案。
D

Would it surprise you to learn that, like animals, trees can communicate with each other and pass on their wealth to the next generation--their young trees?
Suzanne Simard, forest ecologist at the University of British Columbia, explains how trees are much more complex than most of us ever imagined. Simard and her colleagues have made the major discovery that trees and plants really do communicate and interact with each other.
Trees live on through their group work and support, passing around the resources such as nitrogen and carbon “depending on who needs it by 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 system works in a very similar way to the networks of neurons（神經元） in our brains, and when one tree is cut down, it affects all.
Simard talks about "Mother Trees". These are the largest, oldest trees that rise above the forest, a concept explained in the movie Avatar. 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 these trees pass on the wealth to the next generation, transporting important resources 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 losing 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 a chance.” If we could send this message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

Answer 1

【答案】
（1）B
（2）B
（3）B
（4）D
【解析】文章介紹樹和樹之間不是你死我活的競爭關系，它們之間是相互依賴的，快要死的樹會將自己的營養(yǎng)傳給小樹讓它們更好的成長，人們如果知道這些現(xiàn)象，就可以更好的保護這些樹。
⑴細節(jié)理解。根據第三段passing around the resource……by miles of underground fungi networks……give and receive just the right amount to keep them all healthy. 可知森林里的樹木是通過一個龐大的地下真菌網絡使得整個森林生態(tài)系統(tǒng)的樹木得到一樣的營養(yǎng)以保證他們的健康。故選Ｂ。
⑵推理判斷。根據第四段Mother Trees” are connected to all the other trees……pass on the wealth to the next generation可知母樹將營養(yǎng)傳遞給下一代。故選Ｂ。
⑶詞義猜測。it出現(xiàn)在文章最后一段：實際上it指代的是第四段提到的內容，人們砍倒快死的mother trees是不知道樹的社會的依存關系，可知it指的是“樹的社會”是怎么運作的，故選B。
⑷主旨大意。根據全文內容，可知文章介紹樹和樹之間不是你死我活的競爭關系，它們之間是相互依賴的，快要死的樹會將自己的營養(yǎng)傳給小樹讓它們更好的成長，從第一段的句子：Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?可知作者想要表達的是樹要比我們想象的要更加令人驚嘆，所以選D。
