Question

【題目】 Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation(代)?

UBC Professor Simard explains how trees are much mere complex(復(fù)雜的)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(合作)and support, passing around necessary nutrition(營(yíng)養(yǎng))"depending on who needs it". Nutrition is shared through miles of underground fungi(真菌)networks, making sure that all trees in the forest ecological(生態(tài))system give and receive 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 head, and when one tree is cut down, it influences the whole forest.

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(礦物質(zhì))to young trees so they may continue to grow. When humans cut down “mother trees” without noticing these highly complex "tree societies" or the networks on which they feed, we are reducing they chances of survival for the 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 to our environmental protection efforts for the future.

A.look the largest in size in the forestB.pass on nutrition to young trees

【2】The underlined word "it" in the last paragraph refers to________.

C.how the forestry industry developsD.how young trees survive

【3】What would be the best title for the passage?

A.Old Trees Communicate Like HumansB.Young Trees Are In Need Of Protection

C.Trees Are Useful to Our SocietyD.Trees Are More Admirable Than You Think

短文大意：文章介紹樹(shù)和樹(shù)之間不是你死我活的競(jìng)爭(zhēng)關(guān)系，它們之間是相互依賴的，快要死的樹(shù)會(huì)將自己的營(yíng)養(yǎng)傳給小樹(shù)讓它們更好的成長(zhǎng)，人們?nèi)绻�知道這些現(xiàn)象，就可以更好地保護(hù)這些樹(shù)。

【1】句意：“母樹(shù)”是非常重要的，因?yàn)樗鼈儼褷I(yíng)養(yǎng)傳給幼樹(shù)�？疾榧�(xì)節(jié)理解。根據(jù)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.可知“母樹(shù)”之所以重要是因?yàn)樗鼈儗�營(yíng)養(yǎng)傳給小樹(shù)，故選B。

【2】句意：最后一段劃線的“它”指的是“樹(shù)木群落”是如何運(yùn)作的�？疾樵~義理解。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(shù)的社會(huì)tree societies的依存關(guān)系，可知it指的是“樹(shù)的社會(huì)”是怎么運(yùn)作的；how "tree societies" work符合文意，故選A。

【3】句意：這篇文章最好的標(biāo)題是什么?考查標(biāo)題歸納。根據(jù)短文內(nèi)容，可知文章介紹樹(shù)和樹(shù)之間不是你死我活的競(jìng)爭(zhēng)關(guān)系，它們之間是相互依賴的，快要死的樹(shù)會(huì)將自己的營(yíng)養(yǎng)傳給小樹(shù)讓它們更好的成長(zhǎng)；結(jié)合第一段的句子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(shù)要比我們想象的更加令人驚嘆，Trees Are More Admirable Than You Think符合文意，故選D。
