The culprit is climate change, and some researchers found that rising temperatures are having harmful effects on at least five species of rabbit in the US.Take the Lower Keys Marsh rabbit, for instance. An endangered species that lives in the Lower Florida Keys, this species of cottontail is a great swimmerit 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 0.9meter rise would wipe out their habitat(栖息地)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 78 inches long, pikas live high in the cool, damp mountains west of the Rocky Mountains. As global temperatures rise, they would naturally migrate(迁移) to higher groundbut they already occupy the mountaintops. They cant 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, pygmy rabbits weigh less than 1 pound and live in the American West. They are believed 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.36The writer mentions Easter at the beginning of the passage in order to _Ashow the importance of Easter DayBintroduce the issue about bunniesCremind people of Easter traditionsDdiscuss the relationship between Easter and bunnies37The word “culprit”(Paragraph 2)is closest in meaning to _Acriminal Bjudge Cvictim Dproducer38According to the passage, some rabbits can now be easily discovered by predators because they _Aare exposed to more skillful huntersBhave moved to habitats with fewer plantsChavent adapted themselves to climate changeDcant change their fur color into white in the fall and the spring39The problem faced by volcano rabbits and rock rabbits is that _Aboth are affected by less snowBboth are affected by rising sea levelsCneither can find enough foodDneither can migrate to higher places40Which best describes the writers tone in the passage?AApproving.

DDoubtful.课时作业(三十三).1.D考查动词用法。urge 后的从句用虚拟语气(should) do，根据文意，此处应用被动语态。2C考查动词辨析。witness意为“目睹”。此处指目睹巨变。watch观看，注视；observe观察，注意到；realize意识到，实现。3C考查名词辨析。public awareness意为“公众意识”，其他不符合题意。4Bit作形式宾语指代句子后面that引导的宾语从句。句意：为什么你不让他注意到你病得太严重了，不能工作？5B考查名词词义辨析。既然是帮助无家可归者，那么四个选项中只有accommodation(住处，膳宿)符合。句意：洪水过后，当地政府向无家可归者提供了住所。possession 财产；souvenir 纪念品；grocery 食品杂货店。6A考查时态和语态。句意：21世纪已过去的10年见证了中国在各个领域快速、稳定的发展。句子的主语是表示时间概念的短语“the last decade of the 21st century”，witness意为“见证，目睹”，为及物动词，其宾语应该是空格后的所有部分。此时应该用主动语态，视为一种拟人化的手法，再结合时间可知应该用一般过去时。由此可知选A。7B考查非谓语动词。句意：反思过去的错误，Ted意识到他交错了朋友。根据句意可知主语Ted和动词reflect之间是主谓关系，故用现在分词短语作状语。8A考查动词短语辨析。句意：我在厨房里帮忙的时候，没有什么比能够完全按照顾客希望的方式做好鸡蛋，给他们端上桌更让我感到高兴的了。help out帮忙；figure out算出，想出；work out计算出；find out查明，弄清楚。A项符合句意，故选A。 9A考查非谓语动词。此处是动名词形式作主语。10C考查动词辨析。句意：银行附近频繁的抢劫案促使当地警方立即采取行动，打击犯罪。urge“催促；极力主张”，urge sb.to do sth.“敦促某人做某事”，符合句意。 charge收费，控诉；impress使印象深刻，使铭记。11B考查状语从句。句意：在失业率和犯罪率高的地方，人们可以这样认为，是失业导致犯罪。根据上下文逻辑关系，可知应该用地点状语从句，故选B。12C句意：你根本就无法体会，在脚伤得那么厉害的情况下她是怎样完成接力比赛的。这里是一个with的复合结构。13A考查动词词义辨析。abandon 放弃(信念、原则、希望等)；release 释放，放出；discourage 使消极/沮丧；resign 辞职，放弃(工作、职位)。句意：试了多次后，他们不得不放弃了挽救这只受伤严重的大象的希望。14C考查动词时态。句意：汤姆并不是真在这里工作。他只是在这里帮忙，直到他哥哥康复再来上班为止。本题用现在进行时表示目前的情况。help out意为“帮助(摆脱困境或危难)”。15C考查非谓语。句意：正在进行的研究证明我的观点是正确的，我们公司应该立即采取行动。being carried out是现在分词的被动形式作定语修饰research，意为“正在进行的研究”。A、B、D都没有被动之意。.本文是一篇夹叙夹议文。人性生来是善还是恶？在一次风雪历程中，我得到了陌生人的帮助，同时，也给了别人帮助。因此，我坚信：人性本善。16D考查动词词义辨析。spend意为“度过；花费”；check意为“检查”；observe意为“观察；庆祝”；look意为“看”。由语境可知，前一天晚上我看天气预报。look at意为“看”。故D项正确。17C考查形容词词义辨析。预报说雪大概有三英寸厚，我想情况不是很糟糕。故C项正确。18C考查动词词义辨析。由语境可知，开始向Niles，M1靠近时，周围不是很清楚了。故C项正确。19B考查动词词义辨析。concern意为“关系到；涉及”；meet意为“碰到”；involve意为“包含；牵涉”；point意为“指向”。由语境可知，“我”看到了不祥的乌云。故B项正确。20D考查名词词义辨析。way意为“方法；道路”；event意为“事件”；result意为“结果”；sign意为“迹象；符号”。由语境可知，“我”看到乌云后想这不是个好兆头。故D项正确。21A考查名词词义辨析。weather意为“天气”；direction意为“方向”；position意为“位置”；system意为“制度；体制”。由语境可知，在美国这个地方，这样的天气变化是很普遍的。故A项正确。22B考查形容词词义辨析。frozen意为“冻结的”；stuck意为“被卡住的；不能动的”；hurt意为“受伤的”；lost意为“失去的”。由语境可知，来到人口密集的South Bend，车子陷入雪中动弹不了。get stuck意为“被卡住”。故B项正确。23A考查动词词义辨析。attempt 意为“企图；试图”；need意为“需要”；realize意为“意识到”；have to意为“不得不”。由语境可知，车子陷入雪中后，“我”试图左拐到街上。现在分词短语作伴随状语。故A项正确。24D考查动词词义辨析。wait意为“等待”；stay意为“停留”；insist意为“坚持”；struggle意为“努力；挣扎”。由语境可知，我自己在雪中努力了二十分钟。故D项正确。25C考查形容词词义辨析。由语境可知，这不是一条很繁忙的街道，因此没有看到很多人。故C项正确。26A考查副词词义辨析。immediately意为“立刻”；carefully意为“仔细地”；eventually意为“最后；终于”；obviously意为“显然”。当我发现另一位女士的车子也被大雪卡住时，“我”立刻下车。故A项正确。27C考查动词词义辨析。request意为“要求”；attract意为“吸引”；inspire意为“鼓舞；激发”；convince意为“说服”。由语境可知，“我”得到了别人的帮助，因此受到鼓舞也想去帮助她。故C项正确。28A考查名词词义辨析。effort意为“努力”；group意为“团体”；donation意为“捐款”；spirit意为“精神”。后来又有其他人跟“我”一起努力帮忙。故A项正确。29B考查动词短语辨析。make up意为“弥补；组成”；end up意为“结束”；come up意为“走进；开始”；grow up意为“成长”。South Bend最终以三英尺厚的雪而结束了这次风暴。故B项正确。30D考查名词词义辨析。attitude意为“态度”；character意为“性格；品质”；manner意为“方式”；act意为“行为”。联系上文可知，此处指那些友好的行为。故D项正确。31B考查动词词义辨析。inform意为“通知；报告”；remind意为“提醒；使想起”；warn意为“警告”；tell意为“讲述”。由语境可知，他们的行为再一次提醒了我，人性本善。故B项正确。32D考查名词词义辨析。favor意为“赞成；喜欢”；course意为“过程；道路”；caution意为“小心；谨慎”；risk意为“风险”。由语境可知，他们冒着自己车子被困的危险来帮助“我”。故D项正确。33A考查形容词词义辨析。automatic意为“无意识的；必然的”；generous意为“慷慨的”；valuable意为“有价值的”；accurate意为“精确的”。由语境可知，“我”帮助那位女士是一种无意识的反应。故A项正确。34C考查介词辨析。for a second意为“一会儿”。此处指“我”根本想都没想(就帮助了她)。故C项正确。35B考查动词词义辨析。find意为“发现”；produce意为“生产；引起”；admire意为“钦佩；赞美”；judge意为“判断”。由语境可知，在现实生活中，良好的生活氛围可以激发人们养成好习惯。故B项正确。.本文是一篇科普性短文。提到复活节，人们自然想到复活节兔子，它是复活节的象征之一，象征着重生与希望，但是现在由于气候变暖，兔子们处境危险，本文以几种兔子的实际情况加以说明。36B推理判断题。根据常识可知，一提到复活节，人们自然会想到复活节兔子，再看后文大篇幅介绍几种兔子的处境，不难看出开篇提及复活节是为了引出有关兔子的话题。37A词义猜测题。上句说不是孩子们拽兔子耳朵的问题，重点是后文所说的气温升高对美国至少五种兔子的不好的影响，所以气候变化是罪魁祸首，culprit相当于criminal，意为“灾难制造者，犯罪者”。38C推理判断题。从第二段知，受气候的影响，兔子们遇到了困境。比如第三段提到的Lower keys Marsh rabbit和第四段提到的the snowshoe hare都反映出它们对环境变化的不适应，这才是造成它们受困的原因。故选C项。39D细节理解题。介绍rock rabbits时说：they would naturally migrate to higher groundbut they already occupy the mountaintops.They cant go any higher；另外说：The volcano rabbit has the same problem.but there are not suitable plants for them to move higher显然这两种兔子面临的问题是没有更高之地迁徙了。故选D。40B作者态度题。文章首尾呼应，作者对兔子的生存环境充满了担忧与关注。A项意为“赞许的”；B项意为“关心的，担忧的”；C项意为“热情的”；D项意为“怀疑的”。8
