【语篇解读】　最近一项新的研究发现，在中非森林中活动的大象能促进生长缓慢的树木的生长，并能提高森林贮存碳的能力。

人类非法猎杀大象不仅会使大象面临灭绝的威胁，而且会对气候造成不良影响。

1．WhatcanweinferaboutslowgrowingtreesinParagraph2?

A．Theyareelephants'favoritefood.

B．Theyareeasilyhurtbyelephants.

C．Theycanhelpforestsstorecarbon.

D．Theymayreduceelephantpopulations.

C　[推理判断题。

根据第二段尾句中StephenBlake所说的话“Astheelephantsthintheforest，theyincreasethenumberofslowgrowingtreesandtheforestiscapableofstoringmorecarbon”可知，大象的活动增加了生长缓慢的树木的数量，这使森林能贮存更多的碳。

据此可以推知，生长缓慢的树木有利于森林贮存碳，故C项正确。

2．WhatwouldhappenwithoutelephantslivinginCentralAfricanforests?

A．Climatechangewouldpossiblybespedup.

B．Theforeststructurewouldremainunchanged.

C．Theforestswouldlosemorefastgrowingtrees.

D．Largertreeswoulddefeatfastgrowingspecies.

A　[推理判断题。

根据第三段最后两句“Conversely（相反地），shouldforestelephants...potentiallyacceleratingclimatechange”可知，如果森林中的大象灭绝，那些生长缓慢的树木将努力地与生长迅速的物种竞争，这将导致地面生物量减少7%。

其结果是，中非森林将失去高达30亿吨的碳，这有可能加速气候变化。

据此可以推知，如果中非森林中没有大象，则该地区的气候可能会加速变化，故A项正确。

3．WhatdidMr.Berzaghisuggestpeopledo?

A．Leadalowcarbonlife.

B．Evaluatethecarbonloss.

C．Stopdestroyingforests.

D．Protectforestelephants.

D　[细节理解题。

根据本文尾句“Butitdoesseemcertain...wouldbringclimatebenefits”可知，Berzaghi先生认为，停止非法捕杀并恢复森林中大象的数量，会给气候带来好处。

据此可知，Berzaghi先生提议保护森林中的大象，故D项正确。

4．Whatisthebesttitleforthetext?

A．HumansandNatureLiveinHarmony

B．ElephantsDisappearinPartsofAfrica

C．ClimateChangeAffectsForestStructure

D．ElephantsDefendAgainstClimateChange

D　[标题判断题。

通读全文可知，本文第一句和最后一句概括了全文的主旨，又结合文中的其他内容可知，本文通过分析中非森林中大象的活动对气候变化的影响，说明了保护森林中的大象对气候有好处，故D项最适合作本文标题。
