第4讲 逻辑关系解疑难
内容索引
解题策略
语篇是由一些意义相关的句子根据一定的逻辑关系组织起来的语义整体。逻辑关系隐藏在句子中、句与句之间以及段落的衔接中,体现作者的写作思路和篇章意义,是贯穿整篇文章的主线。
完形填空中的任何一道题该选哪个选项,在文中必有依据。因此,解答完形填空最基本的方法就是根据空格前后所提供的信息或上下文之间的逻辑关系,由逻辑关系中已知部分推断出未知部分,做出符合逻辑的判断。
完形填空中主要考查七大逻辑关系:对立关系、并列和递进关系、目的和因果关系、条件关系、时间关系、层次和顺序关系、例证关系。
1.对立关系
对立关系包括让步、对比和转折关系,常见的标志词和短语有:but,however,yet(然而,但是),on
the
contrary(相反),by
contrast(相比之下),unfortunately,although,even
though,while,nevertheless(然而,不过),whereas(然而,反之),in
spite
of(尽管),regardless
of(不管,不顾),anyhow,after
all(毕竟),instead
of(而不是),rather
than(而不是),not...but,otherwise(否则),or
else,to
the
opposite(对立面),compared
with等。

17.A.experienced
B.suffered
C.prevented
D.felt
解析 根据空格前的but与空格后的in
a
clever
way及“Chat
benches.”可知,虽然孤独会导致很多问题,但可以通过长椅聊天的方式来预防(prevent)。

it
42.easy

tunes.
40.A.Therefore
B.However
C.Thus
D.Moreover
解析 本空应用过渡词,后文提到他在随意地弹钢琴(playing
idly
on
the
piano),音乐老师也在倾听(listen),由此可知他开始接触乐器了,与上文构成语意上的转折关系,因此选however“可是”。therefore和thus表示因果关系;moreover表示递进关系。

2.并列和递进关系
并列和递进关系常用的标志词和短语有:and,or,neither...nor...,not
only...but
(also)...,similarly等。

28
conversations.
28.A.formal
B.joyful
C.awkward
D.crazy
解析 空格前的and连接两个表达相同感彩的词,均用来修饰conversations。由active可知,人们进行着积极愉快的(joyful)谈话。

3.目的和因果关系
目的和因果关系常用的标志词和短语有:because,for,since,as,thus(因此),hence(因此),therefore,so,so...that,such...that,in

4.条件关系
条件关系常用的标志词和短语有:if,unless,whether,supposing,on
condition
that,provided
that,depending
on等。

the
first
place,last,next,second,secondly,third,thirdly,to

深度演练
第一步:请快速阅读下列短文,并利用上面所学完形填空的解题技巧巧解下列试题。
体裁:议论文 主题语境:人与社会——堆积如山的垃圾
语篇解读 
文章主要讲的是堆积如山的垃圾给环境带来的影响。
In
our
modern
world,when
something
wears
out,we
throw
it
away
and
buy
a
new
one.The
1
is
that
countries
around
the
world
have
growing
mountains
of
2
because
people
are
throwing
out
more
rubbish
than
ever
before.
1.A.key
B.reason
C.project
D.problem
2.A.gifts
B.rubbish
C.debt
D.products
解析 联系后文的“countries
around
the
world
have
growing
mountains
of...rubbish
than
ever
before”可知,堆积如山的垃圾已经成了社会问题(problem)了。key关键;reason原因;project工程。
解析 根据下文中的“throwing
out
more
rubbish”可知,因为人们扔的垃圾越来越多,垃圾已经堆积成山。故选B。


How
did
we
3
a
throw-away
society?First
of
all,it
is
now
easier
to

an
object
than

time
and
money
to
repair
it.
3.A.face
B.become
C.observe
D.change
4.A.hide
B.control
C.replace
D.withdraw
解析 由空后的“a
throw-away
society”及后文的几个原因可知,此句意为:我们是如何成为(become)一个随手扔的社会的?face面对;observe观察;change改变。
解析 结合空前的“easier
to”和后文的“than
to
spend
time
and
money
to
repair
it”可知,替换(replace)一件东西比花时间和金钱修理它要容易得多。hide隐藏;control控制;withdraw撤回,退出。

.
5.A.Thanks
to
B.As
to
C.Except
for
D.Regardless
of
6.A.safe
B.funny
C.cheap
D.powerful
解析 “modern
manufacturing(制造业)
and
technology”是“companies
are
able
to
produce
products
quickly
and
inexpensively”的原因,因此用thanks
to“多亏,由于”。as
to至于;except
for除了;regardless
of不管,不考虑。
解析 结合前文的“quickly
and
inexpensively”可知,此处是指“产品充足,价格便宜(cheap)”。safe安全的;funny有趣的;powerful强有力的。


Another

is
our
7
of
disposable(一次性的)
products.As
8
people,
7.A.love
B.lack
C.prevention
D.division
8.A.sensitive
B.kind
C.brave
D.busy
解析 从后文的“to
save
time
and
make
our
lives
easier”可知,此处指忙碌的(busy)人们。sensitive敏感的;kind善良的;brave勇敢的。
解析 从后文“we
are
always
looking
for
to
save
time
and
make
our
lives
easier”可知,我们对于一次性产品的喜爱(love)是我们制造太多垃圾的另一个原因。lack缺乏;prevention阻止;division分开,分割。

9.A.ways
B.places
C.jobs
D.friends
10.A.donate
B.receive
C.produce
D.preserve
解析 前文讲到一次性产品的使用,因此我们总是寻找能节省时间和让我们的生活变得更容易的方式(way)。place地方;job工作;friend朋友。
解析 由主语Companies可知,工厂应该是生产(produce)大量的一次性产品。donate捐赠;receive收到;preserve保存。


Our
appetite
for
new
products
also
11
to
the
problem.We
are
12
buying
new
things.
11.A.adapts
B.returns
C.responds
D.contributes
12.A.tired
of
B.addicted
to
C.worried
about
D.ashamed
for
解析 联系空前的“Our
appetite
for
new
products
also”可知,我们对新产品的渴望也导致了(contribute
to)这个问题。adapt适应;return返回;respond回答,回应。
解析 结合“Our
appetite
for
new
products”可知,我们是对购买新的东西上瘾(be
addicted
to)了。be
tired
of厌倦;be
worried
about担心;be
ashamed
for为……感到羞愧。

13.A.newer
B.stronger
C.higher
D.larger
14.A.pick
up
B.pay
for
C.hold
onto
D.throw
away
解析 上句中的“new
things”及后面的“with
the
latest
products”都暗示该空填newer。句意为:广告说服我们,越新的越好,有最新的产品我们会更开心。stronger更强壮的;higher更高的;larger更大的。
解析 联系后文的“to
make
room
for
new
ones”可知,我们常常是扔掉(throw
away)还有用的物品,去给新的东西腾出地方。pick
up捡起,收听,学会;pay
for支付;hold
onto抓住不放。


All
around
the
world,we
can
see
the
15
of
this
throw-away
lifestyle.
Mountains
of
rubbish
just
keep
getting
bigger.
15.A.advantages
B.purposes
C.functions
D.consequences
解析 从后文的“Mountains
of
rubbish
just
keep
getting
bigger.”可知,在全世界我们都可以看到这种随手扔的生活方式所带来的后果(consequence)。advantage好处;purpose目的;function功能。

To

16.A.show
B.record
C.decrease
D.measure
17.A.technology
B.environment
C.consumers
D.brands
解析 结合后文的“more
governments
are
requiring
people
to
recycle
materials”可知,此处指减少(decrease)垃圾的数量。show展示;record记录;measure测量。


解析 减少垃圾,回收利用的目的是保护环境(environment)。
18
,this
is
not
enough
to
solve
our
problem.
18.A.However
B.Otherwise
C.Therefore
D.Meanwhile
解析 联系空后的“this
is
not
enough
to
solve
our
problem”可知,空前后为转折关系,故用however。otherwise否则;therefore因此;meanwhile同时。

19.A.by
B.in

of
C.after
D.instead
of
20.A.spending
B.collecting
C.repairing

解析 从空前的“We
need
to
repair
our
possessions”可知,我们需要修理我们的物品以便再用,而不是(instead
of)扔掉它们。by通过;in
favour
of支持;after在……之后。
解析 结合前文“Our
appetite
for
new
products”及后文“Repairing
our
possessions
and
changing
our
spending
habits...”可知,我们也需要重新考虑我们的消费(spend)态度了。collect收集;repair修理;advertise做广告。

文体链接——议论文
1.结构清晰,脉络有序。议论文是高考完形填空较难的一种文体,一般由三个要素组成:论点、论据、结论。论点和论据形成一体,相互印证。有时作者为了使文章脉络清楚,行文流畅,会使用一些连接词,如:on
the
contrary,all
in
all,in
short,generally
speaking,worse
still,on
the
other
hand,in
conclusion,as
a
consequence等。
2.首句制胜,论点明确。议论型完形填空的首句常常是文章的主旨句。作者一般在文章的首段提出论点,然后在各段的首句提出分论点。
3.不同的议论文论点的提出方式不同,有以下三种情况:①开门见山地提出论点,然后再通过具体的论据去说明论点,论据有时候既有正面的论据,也有反面的论据,最后总结全文。②导入式提出论点。先通过叙述生活中的一件具体的事情或描述生活中的现象,然后根据事情或现象所反映的问题提出自己的论点,再用具体的论据去说明自己的论点。③最后提出论点。有些议论文一开始作者仅仅是列举生活中的现象,不表明自己的观点,是通过对具体现象的分析,最后得出一种结论。本文属于第②类。
