使用无人机检查电力线路使无人机应用于铁路线路成
为可能;第三段讲到了使用无人机大幅节省维护成本
和更好地保护铁路人员安全;第四段讲到了通过使用
最新的技术,无人机还可以开始为铁路提供更高的价
值,可知文章主要讲述了无人机将如何改变铁路的未
来,所以D项“无人机将如何改变铁路的未来。”符合文
章中心思想,适合作为本文的最佳标题。
Passage 11
[语篇解读]本文是一篇说明文。为解决司机在开车时
使用手机造成“分神”,引发交通事故的问题,纽约的一名
立法者提出使用Textalyzer(短信监控器)的技术来监控司
机在开车的时候是否使用了手机。
8.A推理判断题。根据第一段中“Over the last seven
years,most states have banned texting by drivers,and
public service campaigns have tried a wide range of meth-
ods to persuade people to put down their phones when
they are behind the wheel.(在过去的七年里,大多数州
都禁止司机发短信,公共服务活动也尝试了各种各样的
方法来说服人们在开车时放下手机。)”以及第二段中
"Yet the problem,by just about any measure,appears to
be getting worse..(然而,无论以何种标准衡量,这个问题
似乎都在恶化。)”可知,大多数州使用了各种各样的方
法说服司机们在开车的时候放下手机,可是情况却越来
越糟糕。所以各种方法是无效的。A选项ineffective意
为“无效的”,与此相符。
9.B细节理解题。根据倒数第二段中“The technology
could determine whether a driver had just texted,
emailed or done anything else that is not allowed under
New York's hands--free driving laws..(这项技术可以确
定司机是否发了短信、发了邮件,或者做了纽约免提驾
驶法不允许的其他事情。)”可知,Textalyzer能够确定的
是司机是否使用了手机发短信、邮件以及其他驾驶法不
允许的行为。B选项意为“是否司机使用了手机。”与此
相符。
l0.D词义猜测题。根据句中的“We need something on
the books that can change people's behavior,(我们需要
一些能改变人们行为的东西,)”可知,something是能够
改变人们的行为的事情。根据下文的“If the Textalyzer
bill becomes law,he said,'people are going to be more
afraid to put their hands on the cell phone.'(他说,如果
Textalyzer法案成为法律,‘人们会更害怕拿起手机,')”
可知,人们的行为会改变的条件是当Textalyzer法案成
为法律。收到法律的约束和惩罚,司机们才不会在开车
的时候使用手机。故something指代的是法律。
11.B主旨大意题。纵观全文,第一段和第二段闸述的是
“虽然大多数州已经尝试了各种各样的方法来说服人们
在开车时放下手机。可是问题却越来越严重”。第三段
中“That is partly because people are driving more.(部分
原因是开车的人越来越多。)”可知,解释了该行为产生
的部分原因。第四段至第五段讲述的是为了解决该问
题,纽约立法者提出了一个新的想法即利用Textalyzer
技术来监控司机在开车的时候是否使用了手机。最后
一段讲述的是:相关人士呼吁该项技术能够成为真正的
法案,由此才能真正的改变人们的行为。故B选项Tex-
ting and Driving?Watch Out for the Textalyzer(发短信
还是在开车?防范短信监控器)”适合做文章的标题。
主题语境3人与自然
1.自然生态
Passage 1
[语篇解读]文章主要探讨了海拔高度的相对性,以及海
平面作为参考,点的历史演变。作者通过个人经历引出对
海平面概念的思考,并介绍了其著作中关于平均海平面历
史的研究。
28.C细节理解题。根据第一段“But elevation is necessa-
rily relative:only the choice of a reference point allows
us to express numerically the height of an object or a lo-
cation.(但海拔必定是相对的:只有选择一个参考点,
我们才能用数字表达一个物体或位置的高度。)”可知,
作者在文章开头指出海拔的概念是相对的。
29.B段落大意题。根据第三段“Resting on a pass near
the Pradidali hut,we began discussing the readings of-
fered by our altimeters(测高仪).Why did they vary
ever so slightly from one instrument to the next?This
sense of uncertainty led me to think about the meaning
of zero.This is how I began my search for the concep-
tual history of sea level.(在Pradidali小屋附近的山口
休息时,我们开始讨论测高仪上的读数。为什么不同
仪器之间的读数略有差异?这种不确定性让我开始思
考零的含义。这就是我开始探究海平面概念史的原
因。)”可推知,本段主要讲述了作者研究工作的起因。
30.C词义猜测题。根据最后一段“Since I began thinking
about this project in August 2011,the issue of sea-level
rise and the need to place it historically have only be-
come more urgent:between then and the end of 2022
the global sea rose by almost 5 centimeters,about half
of the overall rise recorded by satellites since 1993.
从我在2011年8月开始思考这个项目以来,海平面上
升的问题以及将它置于历史背景下的必要性变得愈发
紧迫:从那时到2022年底,全球海平面上升了近5厘
米,约占自1993年以来卫星记录的总体上升幅度的一
半。)”可知,划线词“it”指代前文提到的“the issue of
sea-level rise'”中的“the issue”,即海平面上升的问题。
3l.B推理判断题。通读全文,根据第二段“That the con
cept has a history is easily ignored.We tend to forget
that sea level is a product of technically and culturally
determined assumptions.In this book I tell a story of
these assumptions.(这个概念有一段历史很容易被忽
视。我们往往忘记海平面是技术和文化决定的假设的
产物。在这本书中,我讲述了这些假设的故事。)”以及
第四段“In this book I examine three crucial stages in
the history of mean sea level.(在这本书中,我考察了平
均海平面历史的三个关键阶段。)”可推知,该书主要探
讨海平面的历史。因此,这本书最合适的标题是“海平
面:一段历史”
Passage 2
[语篇解读]这是一篇应用文。文章介绍了大学植物园的
购票规则、游客需遵守的规定,还提及免费周末导览和需
预约的团体导览,助力游客规划参观。
36.C细节理解题。根据第二段“Tickets cannot be used
on any date other than the one they were booked for and
are non-refundable(不可退款的).(这些票只能在预订
的日期使用,其他日期不可使用,而且一经售出不予退
款。)”可知,在预订前往花园的门票之前,潜在游客应
该注意是否能接受该门票预订政策。故选C。
37.C细节理解题。根据Guidelines for Visitors部分
“Children must stay with a grown-up at all times.(孩子
们任何时候都必须与成年人在一起。)”可知,孩子由成
人陪同下可以进入花园。故选C。
38.D细节理解题。根据Guidelines for Visitors部分
“Stick strictly to the paths and lawns(草坪).(一定要
沿着人行道和草坪行走。)”可知,在草坪上行走是被允
许的。故选D。
39.B细节理解题。根据◆Free Drop-in Weekend Tours
部分“The free tours last one hour and start from the
Fountain,near the Main Lawn.(免费导览活动时长一
小时,从靠近主草坪的喷泉处开始。)”可知,免费的周
末旅游从喷泉处开始。故选B。
40.D细节理解题。根据倒数第二段“Our experienced
volunteer guides will help you enjoy the highlights and
provide some of the background history and develop-
ment of this amazing garden.(我们经验丰富的志愿者
导游会帮助您领略这座花园的精华之处,并为您介绍
一些有关这座神奇花园的历史背景和发展历程。)”可
知,团体游中游客可以享受到介绍花园的诞生与成长。
故选D。
Passage 3
[语篇解读]本文是一篇说明文。文章主要讲述了海豹能
感知血液中氧气量并据此改变潜水行为,人类则因陆地氧
气稳定未演化出此能力。
46.A细节理解题。根据第一段中“Most mammals(哺乳
can't directly detect oxygen levels in the blood
supplied to their tissues.Instead,they rely on the ris
ing level of CO2 in their blood to signal that they might
need to take a breath.(大多数哺乳动物不能直接检测
供应给组织的血液中的氧气水平。相反,它们依靠血
液中二氧化碳水平的上升来发出可能需要呼吸的信
号。)”可知,大多数哺乳动物依靠血液中二氧化碳含量
的上升来判断何时呼吸。故选A。
详解详析
47.B细节理解题。根据第三段中“Once the seals got fa-
miliar with the setup,the researchers started to gradu-
ally change the composition of the air in the breathing
chamber,increasing or reducing the levels of oxygen
and CO2 to see an effect on their behavior.Sure e-
nough:the higher the level of oxygen,the longer the
seals stayed at the feeder..(一旦海豹熟悉了这种设置,
研究人员开始逐渐改变呼吸室中空气的成分,增加或
减少氧气和二氧化碳的水平,以观察对其行为的影响。
果然如此:氧气水平越高,海豹在喂食器停留的时间就
越长。)”可知,当呼吸室中的氧气水平升高时,海豹会
在喂食器停留更长时间。故选B。
48.C细节理解题。根据第四段中“Since oxygen levels on
land remain stable,humans don't seem to have evolved
(to notice low blood oxygen levels,sometimes
not even when they're about to pass out in free-diving.
(由于陆地上的氧气水平保持稳定,人类似乎没有进化
出注意到血液中低氧水平的能力,有时甚至在自由潜
水即将昏倒时也没有。)”可知,人类无法察觉血液中低
氧水平是因为陆地上氧气水平稳定。故选C。
49.C细节理解题。根据最后一段中“Because every time
we surface and breathe in,our sensitivity to CO,is de-
creased,even if its levels are already high,and this in-
creases the chance that a person will,without aware-
ness,pass out before they get to the surface.(因为每次
我们浮出水面吸气时,我们对二氧化碳的敏感性都会
降低,即使其水平已经很高,这也会增加一个人在浮出
水面之前无意识地昏倒的可能性。)”可知,潜水员在自
由潜水时经常发生事故是因为他们可能没有及时注意
到二氧化碳水平的上升。故选C。
5O.B推理判断题。根据第一段中“But a recent study
published in Science suggests seals can sense
the amount of oxygen in the blood,and change their div-
ing behavior in response..(但最近发表在《科学》杂志上
的一项研究表明,海豹可以感知血液中的氧气量,并相
应地改变它们的潜水行为。)”和第四段中“The finding
suggests that seals don't just physically respond to oxy-
gen levels by changing their heart rate or breathing,but
that they are sufficiently aware of them to change their
behavior..(这一发现表明,海豹不仅仅是通过改变心率
或呼吸来对氧气水平做出身体反应,而是它们对氧气
水平有足够的意识来改变它们的行为。)”可知,McK-
night的海豹研究表明,海豹能迅速感知氧气水平并据
此采取行动。故选B。
Passage 4
[语篇解读]本文是一篇说明文。文章介绍了一种新型
园艺设计方法一矩阵种植。
28.B词句猜测題。根据上文“Referred to as matrix
planting,this approach aims for nature to do a lot more
of the heavy lifting in the garden,and even some of the
designing.(这种被称为矩阵种植的方法旨在让大自然
在花园中承担更多繁重的工作,甚至承担一些设计工
作。)”可知,矩阵种植是让大自然自身承接更多的工
作;结合常识和划线词所在句“Eschewing fertilizers(化
and power tools,it's based on an elegantly simple
principle:to garden more like nature does.(Eschewing
化肥和电动工具,它基于一个极其简单的原则:更像大
自然那样进行园艺种植。)”中“to garden more like na-
ture does”可推知,要像大自然那样进行园艺种植,让大
自然自身承接更多的工作,就不需要使用化肥和电动
工具。所以划线词“Eschewing'”的意思是“避开、远离”,
与B项“Keeping away from,”同义。
最新真题分类特训·英语
29.D细节理解题。根据第二段中“The concept was born
when German city planners sought to plant large areas
of parkland after World War II in a reproducible way
that would need minimal maintenance.(这个概念诞生
于二战后,当时德国城市规划者试图以一种可复制且
需要最少维护的方式种植大片公园绿地。)”可知,引入
矩阵种植的想法是为了开发低雏护成本的公园绿地。
30.C推理判断题。根据第三段中“Dutch plantsman and
designer Piet Oudolf's gardens popularized this style,
adding artistic flavors to the planting mixes while pla-
ying with color and form,including four-season interest
and serving the needs of wildlife.(荷兰植物学家兼设计
师Piet Oudolf的花园推广了这种风格,在种植组合中
增添了艺术气息,同时玩转色彩和形态,四季都有看
点,还满足了野生动物的需求。)”可知,Piet Oudolf的
花园有艺术气息,很有品味。
3l.A主旨大意题。通读全文,根据第一段中“Referred to
as matrix planting,this approach aims for nature to do
a lot more of the heavy lifting in the garden,and even
some of the designing.Eschewing fertilizers()and
power tools,it's based on an elegantly simple principle:
to garden more like nature does.(这种被称为矩阵种植
的方法旨在让大自然在花园中承担更多繁重的工作,
甚至承担一些设计工作。它避开化肥和电动工具,基
于一个极其简单的原则:更像大自然那样进行园艺种
i.)”和最后一段中“With human inputs dramatically
reduced,the garden's ecology can develop well.Estab-
lished matrix gardens should not need the life support
we give most gardens:fertilizer,dividing,regular wa-
tering.Compared to traditional garden plots,they in-
crease carbon absorption,reduce stormwater runoff and
boost habitat and biodiversity significantly.(随着人'
投入的大幅减少,花园的生态系统可以良好发展。成
熟的矩阵花园不需要我们给予大多数花园的维持手
段:化肥、分株、定期浇水。与传统花园地块相比,它们
增加了碳吸收,减少了雨水径流,并显著改善了栖息地
和生物多样性。)”可知,文章主要介绍了矩阵种植这种
新型园艺设计方法,它让花园更接近自然、野生的状
态,未来园艺可能会朝着这种更自然、野生的方向发
展。故A项“The future of gardening is WILD(园艺的
未来是自然的)”能概括文章主旨,适合做文章标题。
Passage 5
[语篇解读]本文是一篇应用文。文章主要介绍了参加
卡洛秋季徒步节的几种步行方案,及其日期、起点和步行
时间等相关细节。
21.D细节理解题。通读全文,根据文章所给出的四种方
案中的“Walk Duration(步行时间)”部分比较可知,
“Walk4一Photographic Walk in Kilbrannish Forest(步
行4一基尔布兰尼什森林摄影步行)”的步行时间是1.5
小时,用时最短。
22.A细节理解题。根据文章“Walk3一Moonlight Un-
der the Stars(步行3一星光下的月光)”部分中的“Those
who are dressed inappropriately will be refused permis-
sion to participate.(穿着不当的人将被拒绝参加。)”可知,
第三种步行方案的参与者需要穿合适的衣服。
23.D细节理解题。根据四种步行方案中的“Date and
Time(日期和时间)”部分比较可知,这四种方案都被安
排在周末。
Passage 6
[语篇解读]文章主要介绍了猫的行为及其背后的原因,
帮助读者更好地理解猫的行为。
24.A细节理解题。由第一段内容可知,动物通过不同的
叫声表达自己的需求,如求助、驱赶危险动物或寻找住所
等,表明和大多数动物一样,猫的叫声也是一种生存技能。
25.C细节理解题。由第二段内容可知,猫通过嗅觉来评
估环境和寻找危险的迹象,它们会在选择放松的地方
之前嗅闻特定区域。因此,猫通过嗅觉来评估不同的
情况。
26.D词义猜测题。由第三段中“Dogs are known for
their impressive fetching habit,but cats take this be-
havior up a notch.”以及接下来的描述可知,猫通过带
回物品给主人来表示爱意,这种行为比狗的取物行为
更进一步,即做得更好。
27.B标题归纳题。文章主要介绍了猫的行为及其背后
的原因,帮助读者更好地理解猫的行为,因此最合适的
标题是“理解你的猫的行为”。
Passage 7
[语篇解读]本文是一篇说明文。讲述了美国灰熊从濒
危物种恢复到2000多头,但也带来了一些问题。
32.A细节理解题。根据第一段中“Grizzly bears,which
may grow to about 2.5 m long and weigh over 400 kg,
occupy a conflicted corner of the American psyche-we
revere them even as they give us frightening dreams.
可以长到2.5米长,体重超过400公斤,在美国人的心
理中占据着一个矛盾的角落一
一即使它们给我们带来
可怕的梦,我们也敬畏它们。”可知,美国人对灰熊既有
害怕,又有敬畏,他们的情感是混合的。
33.C推理判断题。根据第三段最后一句“In1975,griz
zlies were listed under the Endangered Species Act.
1975年,灰熊被列入《濒危物种法》。”以及第四段“T0
day,there are about 2,000 or more grizzly bears in the
U.S.Their recovery has been so successful that the U.
S.Fish and Wildlife Service has twice attempted to
delist grizzlies,which would loosen legal protections
and allow them to be hunted.如今,美国大约有2000
只或更多的灰熊。它们的恢复非常成功,以至于美国
鱼类和野生动物管理局两次试图将灰熊从名单上除
名,这将放松对灰熊的法律保护,允许它们被猎杀。”可
推知,由于1975年起受法律保护,灰熊的数量有了
增长。
34.A细节理解题。根据第四段中“Today,there are
about 2,000 or more grizzly bears in the U.S.Their re-
covery has been so successful that the U.S.Fish and
Wildlife Service has twice attempted to delist grizzlies,
which would loosen legal protections and allow them to
be hunted.Both efforts were overturned due to lawsuits
from conservation groups.For now,grizzlies remain
listed.如今,美国大约有2000只或更多的灰熊。它们
的恢复非常成功,以至于美国鱼类和野生动物管理局
两次试图将灰熊从名单上除名,这将放松对灰熊的法
律保护,允许它们被猎杀。由于环保组织的诉讼,这两
次提案都被推翻了。目前,灰熊仍在名单上。”可知,是
环保组织的反对阻止了美国鱼类和野生动物管理局将
灰熊从濒危物种名单上除名。
35.B推理判断题。根据最后一段中“Obviously,if pre
cautions aren't taken,grizzlies can become trouble-
some,sometimes killing farm animals or walking
through yards in search of food.If people remove food
and attractants from their yards and campsites,grizzlies
will typically pass by without trouble.Putting electric
fencing around chicken houses and other farm animal
quarters is also highly effective at getting grizzlies
away.'Our hope is to have a clean,attractant-free
place where bears can pass through without learning
bad habits,'says James Jonkel,longtime biologist who
manages bears in and around Missoula.显然,如果不采
取预防措施,灰熊会变得很麻烦,有时会杀死农场动
物,或者在院子里寻找食物。如果人们把食物和引诱
剂从他们的院子和露营地移走,灰熊通常会安然通过
在鸡舍和其他农场动物生活区周围设置电动围栏也能
有效地赶走灰熊。‘我们希望有一个干净,没有诱饵的
地方,熊可以通过,而不会养成坏习惯,’詹姆斯·琼克
尔说,他是一位长期管理米苏拉市及其周围熊的生物
学家。”可推知,灰熊数量增长,虽然会带来一些麻烦
但是如果采取一些预防措施,人和灰熊可以和谐相处。
Passage 8
[语篇解读]本文是一篇说明文。城市化的发展让人们
越来越难以接触到自然,但一项新研究发现城市中的野生
自然对人类健康和幸福感具有重要影响。研究团队对一
座大型城市公园的游客进行调查,发现与野生自然的互动
可以创造出一种可用的语言,可帮助人们认识和参与最令
人满意和有意义的活动。该研究呼吁保护城市中的野生
自然。
32.B细节理解题。根据第一段内容“As cities balloon
with growth,access to nature for people living in urban
areas is becoming harder to find.If you're lucky,there
might be a pocket park near where you live,but it's un-
usual to find places in a city that are relatively wild.
着城市的飞速发展,生活在城市地区的人们越来越难
以接近大自然。如果你幸运的话,你住的地方附近可
能会有一个袖珍公园,但在城市里找到相对天然的地
方是罕见的。”可知,文章开头作者讲述了一种现象,在
城市里,人们很难找到野生的自然。
33.D推理判断题。根据第三段的“They surveyed several
hundred park-goers,asking them to submit a written
summary online of a meaningful interaction they had
with nature in the park.The researchers then examined
these submissions,coding (experiences into dif-
ferent categories.他们调查了数百名公园游客,要求他
们在网上提交一份书面总结,描述他们在公园里与大
自然有意义的互动。然后,研究人员检查了这些提交
的信息,将体验分为不同的类别。”可知,研究人员按照
公园游客提交的在公园里与大自然互动的活动把游客
分类,再根据第四段“Across the320 submissions,a
pattern of categories the researchers call a nature lan-
guage'began to emerge.After the coding of all submis-
sions,half a dozen categories were noted most often as
important to visitors.在这320份提交的作品中,一种
被研究人员称为‘自然语言’的分类模式开始出现。在
对所有提交的内容进行编码后,有六个类别被认为对
游客最重要。”可知,研究人员对参与者提交的内容进行
了分类,以便在游客的总结中找到模式并确定对游客最重
要的自然体验。通过这样做,他们能够创造一种“自然语
言,”帮助人们认识并参与对他们来说最满意和最有意义
的活动。选项D准确地反映了这一目的。
34.C推理判断题。根据第五段内容“Naming each nature
experience creates a usable language,which helps peo-
ple recognize and take part in the activities that are most
satisfying and meaningful to them.For example,the
experience of walking along the edge of water might be
satisfying for a young professional on a weekend hike in
the park.Back downtown during a workday,they can en-
joy a more domestic form of this interaction by walking
along a fountain on their lunch break.命名每一种自然
体验创造了一种可用的语言,这有助于人们认识并参
与到对他们来说最满意和最有意义的活动中。例如,
沿着水边散步的经历可能会让一个年轻的专业人士在
周末去公园徒步旅行时感到满意。在工作日回到市中
心,他们可以在午休时沿着喷泉散步,享受一种更居家
的互动方式。”可知,本段讲述了自然体验创造了一种
可用的语言,有助于人们识别并参与到对自己来说最
满意和最有意义的活动,接下来以一个年轻的专业人
士参与自然的方式举例说明,去公园时沿着水边散步
让他感到满意,回到市中心工作时他可以通过沿着喷
泉散步获得满足。因此推知,从第五段的例子中我们
可以知道一样的自然体验可以以不同的形式呈现。
35.B推理判断题。根据最后一段“We're trying to generate
a language that helps bring the human-nature interactions
back into our daily lives.And for that to happen,we also
need to protect nature so that we can interact with it,'said
Peter Kahn,a senior author of the study.‘我们正试图创
造一种语言,帮助将人类与自然的互动带回我们的
日常生活中。要做到这一点,我们还需要保护自
详解详析
然,这样我们才能与它互动,’该研究的资深作者彼
得·卡恩说。”可推断,彼得·卡恩认为在我们与大
自然互动之前我们应该先要保护自然。
Passage 9
[语篇解读]本文是一篇说明文。文章主要介绍了一种
会识别形状的凤头鹦鹉。
24.B细节理解题。根据文章第一段“Though not known
to use tools in the wild,the birds have proved skilful at
tool use while kept in the cage.(虽然人们不知道这些
鸟在野外会使用工具,但事实证明,它们在关在笼子里
时就能熟练地使用工具。)”以及“the birds were given
five differently shaped 'key'to choose from.Inserting
the correct 'key’would let out the nut.(研究人员给了
这些鸟5把形状各异的‘钥匙’供它们选择。插入正确
的‘钥匙’会让坚果出来。)”可知,在实验中,凤风头鹦鹉
是通过使用工具从盒子里取出坚果的。
25.C细节理解题。根据文章第二段“In humans,babies
can put a round shape in a round hole from around one
year of age(在人类身上,婴儿从一岁左右就可以把
个圆形的物品放进一个圆形的洞里)”结合选项,可知
一岁儿童最有可能完成“将一个球放进一个圆形的洞
里”的任务。
26.D推理判断题。通过文章最后一段“The next step,
according to the researchers,is to try and work out
whether the cockatoos rely entirely on visual clues,or
also use a sense of touch in making their shape selec-
tions.(根据研究人员的说法,下一步是尝试弄清楚凤
头鹦鹉是完全依靠视觉线索,还是也使用触觉来选择
它们的形状。)”可推知,后续测试的目的是了解凤头鹦
鹉在测试中是否使用触觉。
27.D主旨大意题。通读全文,再结合文章第一段
"Goffin's cockatoos,a kind of small parrot native to
Australasia,have been shown to have similar shape-
recognition abilities to a human two-year-old.(科芬的
凤头鹦鹉是一种原产于大洋洲的小鹦鹉,它的形状识
别能力与两岁的人类相似。)”可推知,本文主要介绍了
会识别形状的凤头鹦鹉。D项“Cockatoos:Skilful
Shape-Sorters(凤头鹦鹅:识别形状的熟练工)”符合文
意,最适合作为本文标题。
2.环境保护
Passage 1
[语篇解读]本文聚焦纽约植树计划暗藏的忧患:现有的
主要树种(橡树和胶皮枫香树)会释放异戊二烯,与氨氧化
物反应形成近地面臭氧,威胁空气质量,间接危害人体健
康,引发人们思考
28.C推理判断题。本题问这项有关橡树和胶皮枫香树的
新研究说明了什么。根据文章第二段中的“Oaks and
sweetgums...produce huge amounts of a chemical sub-
stance called isoprene...to form ground-level ozone-a
major factor in many breathing problems.”可知,橡树和
胶皮枫香树会释放出一种叫作异戊二烯的化学物质,
它与空气中的氯氧化物反应会产生近地面臭氧,是许
多呼吸问题的重要诱因,即这些树木会间接危害人体
健康。故选C项。
29.C推理判断题。本题问科曼基于研究可能提出的建
议。根据文章第二段内容可知,现有的主要树种(橡树
和胶皮枫香树)会间接危害人体健康;第三段中的“f
the city maintains past species patterns in new plant-
ings...ozone levels as much as30%”表明,研究发现,
若在新栽植的树中维持过去的树种模式,异戊二烯和
夏季臭氧水平都将大幅增加;同时根据第四段的科曼
的话可知,科曼赞同多植树,但认为应当谨慎对待植树
活动。由此可推知,科曼可能会建议改变新栽植的树
种。故选C项。
30.B词义猜测题。本题问第五段中的画线短语“oblivi-
ous to”的含义。根据第五段第二句“A study carried
out by some of its researchers several years ago conclu-
ded that city trees did release isoprene.”可知,公园部门
3
