参考答案与解析
(一)
本文是一篇说明文,主要介绍加勒比的箱形水母具有快速的学习能力。
1.C.细节理解题。根据文章第i段中“thetinycreaturesavoidbumpingintothe
roots...Theanswerwas,theycanlearnthis”可知,箱形水母的学习能力使得其可以在
红树林周围安全地生活。
2.A.推理判断题。文章第三段提到“在浑浊的水中,箱形水母最初撞到了墙上。但它们
用了不到八分钟的时间来调整自己的行为。”从中可知,箱形水母的行为改变就是其学习发
生的结果。所以说,箱形水母学习的速度很快。
3.B.推理判断题。文章第四段提到“科学家认为只有当箱形水母受到视觉和机械刺激的
结合时,它们才会真正学到一•些东西”,接着在第五段中提到“科学家把箱形水母的视觉中心
剥离出来,进行轻微的电击进而观察其对水母运动行为的影响”,所以说,把箱形水母的视
觉中心剥离出来的目的是为了研究视觉对箱形水母学习能力的影响。
4.B.细节理解题。根据文章最后一段中“Ifthatstrue,scientistsarestillleftpuzzling
overhowthefourrhopaliaworktogethertomakeupafunctioning,brain-likesystem.M
可知,依然令科学家疑惑的是箱形水母四个视觉中心是怎样协同工作的,也就是rhopalia
的工作机制。
(二)
本文是一篇记叙文,主要介绍MahanChandraBorah创立水稻种子图书馆Annapurna
RiceLibrary保护当地水稻的故事。
1.A.理解具体信息。根据文章第一段中“Asayoungboy,Mahanoftenhelpedhis
fatheroutinthefields.'WorkingwithhiminthefieldsiswhereIlearntallIknowabout
farming,"可知,Mahan在年轻的时候学会了种植水稻。
2.C.推理。文章第二段提到“Mahan发现人们不知道当地水稻有很多种,而这种无知
导致了一些水稻的灭绝,所以他创立了AnnapurnaRiceLibrary",所以说,人们对不同水
稻的无知促使Mahan创立了AnnapurnaRiceLibraryo
3.A.推理。根据第三段中“theloweryieldperhectarehasbeenafactorasthefarmers
donotprefertogrowtherice”可知,BhaoDhan的产量低是人们不喜欢种植的原因。所以
当人们不种植这个水稻,这种水稻最终会走向灭绝。
4.D.理解大意。纵观A文内容可知,Mahan年轻时种植水稻,了解到了一些当地水稻
面临灭绝的状况,然后成立AnnapurnaRiceLibrary让农民可以免费选择一些水稻的种子
进行种植,进而保全那些濒危的水稻种子。所以说,Mahan是一个水稻种子的拯救者。

本文是一篇说明文,主要介绍瑞士制表业在其摇篮Va诞edeJoux的发展史。
1.A.理解具体信息。根据第二段中Withamonopolyofnaturalresourcessuchasa
flowingalpinelake,richirondeposits,andgentian,watchmakingrapidlydeveloped
andflourishedinValleedeJoux.可知,制衣业得以在ValleedeJoux快速发展得益于当地
独特的自然资源。
2.C.推理。第三段提到年轻人学习制表,从而当地的房屋发生改变,因为这样这些年
轻的制表匠可以借助自然光来设计和制表。也就是说,房屋的改变是为了给制表提供便利。
3.B.推理。第四段中NathalieVeysset认为瑞士制表是瑞士人身份的象征,是顶级优
品,享誉全球,可见,NathalieVeysset认为瑞士人以制表为荣。
4.D.推理。最后一段Carlene提到了瑞士制表也曾遭遇危机,但是幸存下来了,并且
这种慢手工技艺可以适应快节奏的科技变革,所以说Carlene对瑞士制表在科技时代的前
景持一种乐观的态度。
(四)
本文是一篇说明文,主要介绍了中国科学家研发了一种合成海绵,这种海绵具有很强
的吸附塑料微粒的能力。
1.A.理解具体信息。根据文章第一段中“Sponges.Isthereanythingtheycantdo?
Forthousandsofyears,humanshaveuseddriednaturalspongestocleanup,topaint
andasvesselstoconsumefluidslikewaterorhoney.”可知,海绵被广泛地使用。
2.C.理解具体信息。根据文章第二段中"whenaspeciallypreparedplastic-filled
