解析
詞義猜測題。根據(jù)畫線詞組下文“Yet
neither
drought
nor
frost
is
ever
a
concern
for
growers
of
plants
currently
grown
inside
large
greenhouses.Vegetables
are
increasingly
being
grown
indoors,using
an
advanced
form
of
growing
called
controlled
environment
agriculture,a
method
that
has
the
potential
to
help
feed
the
planet,even
while
it
threatens
to
further
warm
it.”可知,作者所謂的農(nóng)業(yè)發(fā)生了重大變化,指的是越來越多的人在室內(nèi)種植蔬菜。ⅠⅡⅢⅣ2.Whatdoescontrolledenvironmentagriculturemainlyfocuson?A.Makingcropstastegood.B.Plantingcropswithlesswater.C.Growingcropsinextremeweather.D.Transportingcropsfromalongdistance.答案
A
解析
細節(jié)理解題。根據(jù)文章第二段中的“Above
all,the
produce
can
be
bred
for
flavor,instead
of
for
tolerance
to
heat,rain
and
long-distance
transport.”可知,這種種植方式的重點是為了農(nóng)產(chǎn)品的風(fēng)味,也就是為了讓這些農(nóng)產(chǎn)品嘗起來更好。ⅠⅡⅢⅣ3.WhatdoweknowaboutAmericangreenhousetomatoes?A.Theyarenothigh-yieldingcrops.B.Theyarenotreallyenvironmentallyfriendly.C.Theyaregrownfarfrompopulationcenters.D.TheyaremainlyexportedtoNorthernEurope.ⅠⅡⅢⅣ答案
B
解析
推理判斷題。根據(jù)文章第三段中的“But
various
studies
have
estimated
that,on
average,the
production
of
a
pound
of
tomatoes
in
an
American
or
Northern
European
greenhouse
releases
3
to
3.5
pounds
of
carbon
into
the
atmosphere.That
is
about
6
times
the
carbon
footprint
of
a
field
tomato,even
taking
into
account
the
emissions
from
refrigerated
trucks
that
often
transport
field
vegetables
hundreds
or
even
thousands
of
miles
to
reach
consumers.”可知,在美國溫室培育西紅柿所排放的碳要遠比在田間培育西紅柿多得多,也就是說它們根本不環(huán)保。ⅠⅡⅢⅣ4.Whichofthefollowingstatementsmaytheadvocatesagreewith?A.Greenhouseplantingisanecessarytemporizingmeasure.B.Greenhouseplantingistailoredforsmall-populationnations.C.Greenhouseplantingcanhelpspreadtheideaofhealthyeating.D.Greenhouseplantingshouldbestoppedfromwarmingtheworld.答案
A
解析
推理判斷題。根據(jù)文章最后一段可知,支持這種種植方式的人認為,即便這種種植方式會排放溫室氣體,但是為了地球上的人們,這種種植方式是必要的權(quán)宜之計。故選A項。ⅠⅡⅢⅣBCivilizationbeganwithagriculture,andthoughhumanityhaschangedsignificantly,agricultureremainsveryimportant.Incertaincountries,itssignificanceismoreapparent,buttherealityisthateverycountryintheworlddependsonagricultureforonethingoranother.Itprovidesemployment.Whetherit’sworkingasafarmer,aharvester,atechnicianforfarmequipmentorascientist,thereareplentyofjobsavailableinthisfield.Indevelopingcountries,agriculturaljobshelpreducehighratesofunemployment.ⅠⅡⅢⅣIt’scrucialtoacountry’sdevelopment.Economicdevelopmentistiedtoacountry’sagriculturalsector.Whentrade,nationalavenue,andemploymentarecombinedinapositiveway,acountryenjoysreducedpovertyandboostedeconomicgrowth.Becausestrongagricultureresultsinbenefitsfairlyquickly,focusingonitisoneofthebestwaystospeedupdevelopmentandimproveacountry’sstandingacrosstheglobe.Itdrivesinnovationintechnology.Becausehealthyagricultureissoessentialtoacountry’swell-being,it’sbeenthesettingofsomeofthemostexcitinginnovationsintechnology.Throughartificialintelligence,blockchainsoftware,andmore,scientistsandfarmershavebeenfiguringoutwaystoⅠⅡⅢⅣincreasecropproductivity,uselesswater,andreducenegativeimpactsontheenvironment.Forscientistsandtechcompanies,agribusinessisoneofthemostfascinatingandproductivefieldstoworkin.It’sthesourceofourfoodsupply.Arguably,themostimportantaspectofagricultureisthatit’sthesourceoftheworld’sfoodsupply.Nomatterwhereorwhatyouareeating,theingredientsinyourmealscomefromsomewhere.Allroadsleadtoagriculture.Incountriesdealingwithfoodinsecurityandseveremalnutrition,theiragriculturalsectorsaresuffering.Whenagriculturethrives(蓬勃發(fā)展),fewerpeoplegohungry.ⅠⅡⅢⅣItcanhelphealtheenvironment.Agriculturepossessesthepowertocauseharmorheal.Whenfarmersprioritizebiodiversityontheirland,itbenefitstheearth.Havingmorebiodiversityresultsinhealthiersoil,betterwaterconservation,andhealthierpollinators(傳粉者).Allinall,agricultureplaysacriticalroleintheentirelifeofagiveneconomy.Agriculturecultureisthebackboneoftheeconomicsystemofagivencountry.【語篇解讀】本文是一篇說明文。農(nóng)業(yè)在一個特定經(jīng)濟體的整個生命周期中起著至關(guān)重要的作用,是一個國家經(jīng)濟體系的支柱。文章主要介紹了農(nóng)業(yè)的重要性。ⅠⅡⅢⅣ5.Whatisthetopicofthearticle?A.Civilization. B.Agriculture.C.Economy. D.Environment.答案
B
解析
主旨大意題。通讀全文可知,文章第一段“Civilization
began
with
agriculture,and
though
humanity
has
changed
significantly,agriculture
remains
very
important.In
certain
countries,its
significance
is
more
apparent,but
the
reality
is
that
every
country
in
the
world
depends
on
agriculture
for
one
thing
or
another.”指出農(nóng)業(yè)是很重要的,接著第二、三、四、五、六段從不同的方面具體介紹了農(nóng)業(yè)的作用;最后一段對文章進行總結(jié),指出農(nóng)業(yè)的重要地位,由此可知,文章的主題是農(nóng)業(yè),故選B項。ⅠⅡⅢⅣ6.Whatisexpectedtobeachievedbyusingtechnologyinagriculture?A.Sustainabledevelopment.B.Soundeconomicsystems.C.Lowunemploymentrates.D.Worldwidefoodsecurity.ⅠⅡⅢⅣ答案
A
解析
推理判斷題。根據(jù)第四段中的“Through
artificial
intelligence,blockchain
software,and
more,scientists
and
farmers
have
been
figuring
out
ways
to
increase
crop
productivity,use
less
water,and
reduce
negative
impacts
on
the
environment.”可知,在農(nóng)業(yè)中使用技術(shù)能提高作物產(chǎn)量,減少用水量,并減少對環(huán)境的負面影響,由此可推知,將技術(shù)應(yīng)用到農(nóng)業(yè)中有望實現(xiàn)農(nóng)業(yè)的可持續(xù)發(fā)展。ⅠⅡⅢⅣ7.Whatdoestheauthormeanbyusingtheword“Arguably”inparagraph5?A.Heiscriticalaboutsuchabelief.B.Heisdoubtfulabouttheimportance.C.Heiscertainabouthisstatement.D.Heisconcernedaboutfoodinsecurity.ⅠⅡⅢⅣ答案
C
解析
推理判斷題。根據(jù)第五段中畫線單詞所在句子“Arguably,the
most
important
aspect
of
agriculture
is
that
it’s
the
source
of
the
world’s
food
supply.No
matter
where
or
what
you
are
eating,the
ingredients
in
your
meals
come
from
somewhere.All
roads
lead
to
agriculture.”可知,作者論證了農(nóng)業(yè)是我們食物的來源,由此可推知,作者使用“Arguably”這個單詞是為了表明對自己的陳述很肯定。ⅠⅡⅢⅣ8.Whatisthetextmainlyabout?A.Thedevelopmentofagriculture.B.Thediversityoffarmproducts.C.Thesignificanceoflandfarming.D.Theoriginofhumancivilization.答案
C
解析
主旨大意題。通讀全文,尤其是最后一段“All
in
all,agriculture
plays
a
critical
role
in
the
entire
life
of
a
given
economy.Agriculture
culture
is
the
backbone
of
the
economic
system
of
a
given
country.”可知,文章主要介紹農(nóng)業(yè)的重要性。Ⅱ.七選五ⅠⅡⅢⅣVegan

a
good

such
as

an
approach
to

also
helps
preserve
the

and
regain

and

its

farmers
are

from

synthetic

本段最后一句“On
the
other
hand,vegan
agriculture
rejects
animal-derived
products
and
usually
sticks
with
plant-based
organic
compounds,which
means
that,in
general,vegan
agriculture
has
stricter
rules
than
organic
farming.”可知,本段在說全素農(nóng)業(yè)與有機農(nóng)業(yè)是不一樣的。結(jié)合選項,B項“It
is
apparent
that
vegan
agriculture
is

the

上文“Additionally,vegan

cropping(混作),using
mechanical
barriers
such
as
nets,or
even
attracting

might
be
less
effective
against
certain
plant
diseases
or
pests.”介紹這種方法的弊端,且為轉(zhuǎn)折關(guān)系??赏浦仗帒?yīng)是這種方法的優(yōu)勢。結(jié)合選項,E項“Those
ways

than
the
ways

上文“By
contrast,in
conventional
agriculture,synthetic
pesticides
are
on
a
very
high

上文“Doing

beneficial
to

【語篇解讀】本文是一篇記敘文。當林占熺第一次向?qū)幭母瓯跒┚用窠榻B蘑菇種植時,他沒有想到會取得如此驚人的成功。菌草技術(shù)是一種以草屑為基質(zhì)種植食用蘑菇和藥用蘑菇的方法,其發(fā)明者長期以來一直致力于在扶貧中推廣這種方法。1.The
考查冠詞。此處為特指一種以草屑為基質(zhì)種植食用蘑菇和藥用蘑菇的方法,所以用定冠詞。故填The。2.to
考查介詞。be

to致力于,故填to。3.readily
考查詞性轉(zhuǎn)換。分析句子結(jié)構(gòu),修飾形容詞使用副詞。故填readily。ⅠⅡⅢⅣ4.whose
考查定語從句。先行詞是grass,設(shè)空處在定語從句中作定語,使用whose引導(dǎo)定語從句。5.was

考查動詞的時態(tài)和語態(tài)。分析句子結(jié)構(gòu),設(shè)空處在句子中作謂語,與主語之間為被動關(guān)系,使用被動語態(tài),因句子表達的是發(fā)生在過去的動作,使用一般過去時的被動語態(tài)。故填was
adopted。6.taking
考查非謂語動詞。advocate
doing
sth.主張做某事。故填taking。
