Question

14．Easter （復(fù)活節(jié)） is still a great day for worship，candy in baskets and running around the yard finding eggs，but every year it gets quite a bit worse for bunnies．And no，not because the kids like to pull their ears．The culprit is climate change，and some researchers found that rising temperatures are having harmful effects on at least five species of rabbits in the US．
Take the Lower Keys Marsh rabbit for example．An endangered species that lives in the Lower Florida Keys，this species of cottontail is a great swimmer--it lives on the islands!--but it is already severely affected by development and now by rising sea levels．According to the Center for Biological Diversity，an ocean level rise of only 0.6 meters will send these guys jumping to higher ground and a 0.9-meter rise would wipe out their habitat （棲息地） completely．
The snowshoe hare，on the other hand，has a color issue．Most of these rabbits change their fur color from white in the wintertime to brown in the summer，each designed to give them better cover from predators 捕食者）．As the number of days with snow decreases all across the country，however，more and more bunnies are being left in white fur during brown dirt days of both fall and spring，making them an easier mark for predators．Researchers know that the color change is controlled by the number of hours of sunlight，but whether the rabbit will be able to adapt quick enough to survive is a big question．The National Wildlife Federation has reported that hunters have noticed their numbers are already markedly down．
American pikas or rock rabbits，a relative of rabbits and hares，might be the first of these species to go extinct due to climate change．About 7-8 inches long，pikas live high in the cool，damp mountains west of the Rocky Mountains．As global temperatures rise，they would naturally migrate to higher ground--but they already occupy the mountaintops．They can't go any higher．The National Wildlife Federation reports that they might not be able to stand the new temperatures as their habitat heats up．
The volcano rabbit has the same problem．These rabbits live on the slopes of volcanoes in Mexico，and recent studies have shown that the lower range of their habitat has already shifted upward about 700 meters，but there are not suitable plants for them to move higher，so they are stuck in the middle．Scientists are concerned about their populations．
Native to the US，pygnty rabbits weigh less than 1 pound and live in the American West．They are belie ved to be the smallest rabbits in the world．Their habitats have been destroyed by development．Several populations，such as the Columbia Basin pygmy，almost went extinct and were saved by zoo breeding programs．Pygmy rabbits also rely on winter cover by digging tunnels through the snow to escape predators，but lesser snowfall is leaving them exposed．
All of this gives new meaning to dressing up in a giant bunny costume this Easter．

Answer 1

分析 每年復(fù)活節(jié)可愛的兔子給大家?guī)�來了很多歡樂，然而隨著全球變暖趨勢的加劇，這種給我們帶來愉悅的兔子也不可避免地受到了一定的影響．兔子們處境危險(xiǎn)，本文以幾種兔子的實(shí)際情況加以說明．

解答 32．B 寫作意圖題．根據(jù)常識(shí)可知，一提到復(fù)活節(jié)，人們自然會(huì)想到復(fù)活節(jié)兔子，再看后文大篇幅介紹幾種兔子的處境，不難看出開篇提及復(fù)活節(jié)是為了引出有關(guān)兔子的話題．故選B．33．A 詞義猜測題．根據(jù)畫線后的句子and some researchers found that rising temperatures are having harmful effects on at least five species of rabbits in the US．可知一些研究人員發(fā)現(xiàn)，氣溫升高至少對(duì)美國的五種兔子有不良影響．所以罪魁禍?zhǔn)资菤夂蜃兓�，culprit相當(dāng)于criminal，意為"災(zāi)難制造者，犯罪者"．故選A．34．D 細(xì)節(jié)理解題．根據(jù)文章倒數(shù)第三段的they would naturally migrate （遷徙） to higher ground-but they already occupy the mountaintops．They can"t go any higher．他們會(huì)很自然地遷移到更高的地面，但他們已經(jīng)占據(jù)了山頂．他們不能再高了．和倒數(shù)第二段第二句的后半部分but there are not suitable plants for them to move higher，so they are stuck in the middle．但是沒有合適的植物讓它們遷移到更高的地方，所以它們被夾在中間．可知，兩種兔子面臨的問題是不能往更高處去，故選D．35．B 作者態(tài)度題．文章首尾呼應(yīng)，作者對(duì)兔子的生存環(huán)境充滿了擔(dān)憂與關(guān)注．A項(xiàng)意為"贊許的"；B項(xiàng)意為"關(guān)心的，擔(dān)憂的"；C項(xiàng)意為"熱情的"；D項(xiàng)意為"懷疑的"． 故選B．

點(diǎn)評(píng) 本文是歷史文化類閱讀，主要考查細(xì)節(jié)理解題和推理判斷題．在做細(xì)節(jié)理解題時(shí)，首先根據(jù)題目要求迅速在文章里找出相應(yīng)的段落、句子或短語．認(rèn)真比較選項(xiàng)和文中細(xì)節(jié)的區(qū)別，在做推理判斷題時(shí)不要以個(gè)人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．
