1.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(神經(jīng)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 a 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 文章介紹樹和樹之間不是你死我活的競爭關(guān)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?nèi)绻肋@些現(xiàn)象,就可以更好的保護(hù)這些樹.
解答 9.C,標(biāo)題歸納題,根據(jù)全文內(nèi)容,可知文章介紹樹和樹之間不是你死我活的競爭關(guān)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(dá)的是樹要比我們想象的要更加復(fù)雜,所以選C.
10.A,推理判斷題,根據(jù)句子trees survive through their co-operation and support"樹的生存是通過它們的合作和支持",可以推測樹是彼此依賴的,故答案為A.
11.D,細(xì)節(jié)理解題,根據(jù)句子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,如果"母親樹"被砍下的話,就會影響到整個森林,故答案為D.
12.B,詞義猜測題,it出現(xiàn)在文章最后一段:實(shí)際上it指代的是第四段提到的內(nèi)容,人們砍倒快死的mother trees是不知道樹的社會的依存關(guān)系,可知it指的是"樹的社會"是怎么運(yùn)作的,所以選B.
點(diǎn)評 解答任務(wù)型閱讀理解題,首先對原文材料迅速瀏覽,掌握全文的主旨大意.因?yàn)殚喿x理解題一般沒有標(biāo)題,所以,速讀全文,抓住中心主旨很有必要,在速讀的過程中,應(yīng)盡可能多地捕獲信息材料.其次,細(xì)讀題材,各個擊破.掌握全文的大意之后,細(xì)細(xì)閱讀每篇材料后的問題,弄清每題要求后,帶著問題,再回到原文中去尋找、捕獲有關(guān)信息.最后,要善于抓住每段的主題句,閱讀時,要有較強(qiáng)的針對性.對于捕獲到的信息,要做認(rèn)真分析,仔細(xì)推敲,理解透徹,只有這樣,針對題目要求,才能做到穩(wěn)、準(zhǔn).
