【语篇解读】本文是一篇记叙文，讲述了“我”一家人与继父之间的故事。

1.C句意：我很怀念有爸爸的日子。由“Momwasayoungwidow”可知，“我”的母

亲是个寡妇，所以"我”很怀念(missed)有爸爸的日子。recommended推荐；slopped停止；

minded介意。

2.A句意:然后我走进厨房。iX**Iquietlyplacedmyearagainstthekitchendoor.**

可知，"我"在厨房外偷听，这次直接走进了厨房(kilchen)。bathroom浴室；bedroom卧室；

garden花园。

3.C句意：“帕蒂！”妈吗难为情地责备着我。由"LookingtowardsMom,Iasked,

4Don'tyouthinkmymom'spretty?'"可知，妈妈对于"我“同乔治的问题感到尴尬

(embarrassment)oexcitement兴奋：doubt怀疑；pride自豪。

4.D句意：乔治俯身低声说：“是的，我也是这么认为。”“我”还是个孩子，所

以乔治低声地(whispered)对“我”说，也是为了避免让母亲感到尴尬。也说明乔治是一个温

柔且喜欢孩子的人。yelled喊叫；complained抱怨；reported报道。

5.B句意：乔治开始更频繁地看望妈妈。由“moreoften”可知，乔治开始更加频繁地

看望(callingon)妈妈。takingon呈现；focusingon集中；puttingon±.,上演。

6.A句意：他见到我似乎总是很高兴，对我没完没了的问题从不感到厌烦。由“never,

endlessqueslions”可知，乔治对作者没完没了的问题从不感到厌烦(tired)。uncertain不确定的；

fond喜欢的；confident自信的。

7.C句意：不久他们就结婚了。由"inloaready-madefamily”可知，不久乔治与母

亲就结婚了(marriage),成了作者的继父。conflict矛盾：contact联系；competition竞争。

8.B句意：安妮大声抱怨说，照顾那个被宠坏的孩子不是她的职责。由“Bennywas

cryingonthekitchenfloor.”可知，本尼正在地板上哭，而安妮只有10岁，面对弟弟在地板上

哭个不停，她也没有好办法，所以安妮大声地抱怨(complaining)。warning警告；wondering

想知道；demanding要求。

9.B句意：乔治面色木然，咕哝道：“我一定是疯了(mad),娶了一个有三个孩子的

女人“。talented有天赋的；brave勇敢的；unbelievable难以置信的。

10.C句意：妈妈含泪跑回卧室，乔治走了出来。母亲看到孩子们这么吵闹，再加上

乔治说的那一番话，这一切使母亲泪流满面(lears)。shock震惊；vain徒劳；ruins废墟。

11.A句意：请不要离开。根据"Georgewalkedout.Ihurriedtotheporch.”可知，乔治

走到门厅要走，因此"我”请求乔治不要离开(leave)。refuse拒绝；approach接近;escape

逃跑。

12.B句意：他轻轻地擦着我的眼泪，他说：“我们是朋友，朋友从不抛弃他们所爱

的人。”由前文可知，乔治对“我”所提出的问题从不感到厌烦，所以乔治对待“我”是很

温柔的且很喜欢孩子。所以当“我”请求乔治不要离开时，他轻轻地(Gently)擦着“我”的

眼泪。Deeply深深地；Properly哈当地；Skillfully熟练地。

13.C句意参考上题。根据下文“Georgehasalwaysbeenthereforme.”可知，乔治没有

抛弃(abandon)“我”一家人。persuade劝说；suggest建议;threaten威胁。

14.D句意：然后他去安慰妈妈。乔治对“我”说完话，又去安慰(comfort)妈妈，因

为妈妈哭了。persuade说服；inform告知；auract吸引。可见乔治是很温柔且很爱这个家。

15.B句意：尽管他已经85岁了，我仍然向乔治请求帮助来解决问题。由“myendless

questions”可知“我”小时候会问乔治无尽的问题。现在“我”已经是成年人了，乔治也已

经85岁了，但是"我”在生活中有问题(problems)时，仍然向乔治请教。suggestions建议；

experiences经历；achievements成就。

【语篇解读】本文是一篇说明文，介绍了树对人类的作用非常大，可以给人类提供木材

和遮阴，还可以帮助阻止干旱和洪水。但实际情况是很多人砍掉了很多树木，破坏了植被，

引起了生态危机。

1.ways考查名词复数。句意：树对人类有三个重要的用处。根据空前ihree可知，

本空应用名词复数形式。

2.and考查并列连词。句意：它们给予人类木材和其他有用的东西，它们给予人类凉

爽的地方，并且它们帮助人类阻止干旱和洪水。本空前后句为顺承关系，故应用并列连词

ando

3.the考查冠词。句意：不幸的是，在世界上许多地方，人类还没有发现第三点是最

重要的。序数词third前应用定冠词the。

4.in考查介词。句意：人类想从树木中赚钱，所以他大量地砍伐树木，结果发现没

有了它们，人类失去了最好的朋友。inlargenumbers意为“大量地”，故本空应用介词in。

5.toplant考查动词不定式。句意：而且，他通常太粗心大意，不能种植和照料新树。

本句为too…to…句型，意为“太……而不能……”，故本空应用不定式形式。

6.slowly考查副词。句意：所以森林慢慢地消失了。本空修饰动词disappear,故应

用副词slowly<,

7.worse考查形容词比较级。句意：结果甚至更糟。根据句意及空前even可知，本

空应用形容词比较级形式。

8.beingwashed考查动名词。句意：树木的根部使土爆裂开，雨水渗入，也固定了土

壤，从而阻止土壤轻易被冲走。preventt,,fromdoingsth.意为“阻止做某事”，故应用动名

词的被动式。

9.falls考查时态。句意：没有树的地方，雨水落在坚硬的地面上，然后流走，造成

洪水，带走肥沃的表层土壤。根据空前are及空后flows可知，本空应用一般现在时。

10.isleft考查时态及语态。句意：当所有的表层土壤都消失时，除了无用的沙漠什

么都没留下。本句表述的是客观事实，应用一般现在时，且主语nothing和动词leave之间

为被动关系，故本空应用一般现在时的被动语态。

【语篇解读】本文是一篇记叙文，主要讲述了小狗Luke在一场森林大火中，奋不顾身

地拯救四只小猫和一个消防员的故事。

1.C细节理解题。根据第二段中“There'snolongeranyhopeatthemomenttowaitfor

Luketocomebacktotheshelter.Infact,Iwaswaitingfbrthefirementoannouncemehisdeathin

theforest.”可知，作者原来认为自己的狗有可能在森林中被烧死。

2.A细节理解题。根据第四段中“Thatday,IwasveryproudofLukeforhistwoheroic

actions.”可知，作者对小狗Luke的两次英勇行为感到自豪。根据第二段中“…mydogLuke

succeededinsavingfourcatswhichweretrappedbytheflames.n和第三段中“…theyfound

himbarkingloudlybythesideofaninjuredfiremanwhowaslyingontheground.w可知，这两

次英勇行为指的是救火中被困的四只小猫和一名消防员。

3.B词义猜测题。根据画线词后句“Weshouldloveandprotectihem.Littleanimalscan

makeenormousthingsforhumans.“可知，作者呼吁我们要关爱和保护动物，小动物也能为人

类作出巨大的贡献，我们不要小瞧了它们。由此可推断出Don,tbelittlethem中的画线词意

为“瞧不起(Lookdownupon.)”。

4.D推理判断题。本文主要讲述了小狗Luke在一场森林大火中，奋不顾身地拯救四

只小猫和一个消防员的故事。由此可推断出作者讲述Luke的英勇事迹是为了与读者分享宠

物的爱与关心的故事。

【语篇解读】本文是一篇说明文，介绍了在地震中防止死亡和受伤的一些安全知识。

1.G根据空前句“Ifyou'reinsideabuilding,staythere!Oneofthemostdangerousthings

todoinanearthquakeistotrytoleaveabuilding.“可知，G项和上句有对应的关键词“people

insidebuildingstrytogoout"，而且G项（大多数的伤亡发生在大厦里的人们试图出去的时候）

也能承接上句。

2.B根据空后"Don'ttakeshelterunderatree,streetlights,electricpolesortall

buildings（不要在树下、街灯下、电线杆下或高楼下躲避）.”可知，B项（如果你在外面，你

就要到一个开阔的地方）符合本段的意思。

3.D因D项有与本段上文相同的句式结构（即Don、…），且D项（不要把车停在树下

或任何一个高的物体之下）是补全主题的其他细节，也能承接上文。

4.C根据空前句“Don、shout.”可知，C项中相对应的关键词：shouting,且C项（大喊

会使你吸入灰尘）正好承接上句。

5.F根据本段的主题句“Bepreparedforaftershocks.”和空后的描述可知，F项（余震在

地震后的最初几个小时里就可能发生）正好说明主题的细节，而且和空后的句子构成转折关

【语篇解读】本文是一篇说明文，介绍了中国正在建设世界上最大的地震预警系统。

1.reliable考查形容词。句意：不幸的是，我们没有一个可靠的方法来预测。本空修

饰名词way,故应用形容词reliable,意为“可靠的，可信赖的”。

2.possibly考查副词。句意：它可能是最先进的。本空修饰形容词advanced,故应用

副词possiblyo

3.aresetting考查时态。句意：工程师们正在全国范围内安装超过15,000个传感器，

并将它们连接到一个网络上。根据后面and并列的动词wiring及句意可知，本空应用现在

进行时aresetting(>

4.When/If/Once/After考查状语从句连接词。句意：当/如果/一旦/地震发生时(地震

发生后)，传感器可以向控制中心发送电脉冲。根据句意可知，本空可填When/If/Once/Afier。

5.giving考查现在分词。句意：该信号的传送速度几乎达到光速，比地震的震动速

度还要快，给当地居民一点时间做准备。本空在句中作状语，且和主语“Thesignal”之间为

主动关系，故应用现在分词作状语。

6.which考查非限制性定语从句。本空引导限制性定语从句，修饰“Thesystem"，本

空在从句中作主语，指物，故应用关系代词which。

7.movement/move考查名词。句意：不仅可以探测大陆的运动。根据空前冠词ihe

及空后介词of可知，本空应用名词形式movement或move。

8.of考查介词。ihepossibleimpact8.anearthquake意为"地震可能的影响”，

故本空应填介词of。

9.itself考查代词。句意：它会自动向当地人发出警告，比人类的观察速度快得多。

making的逻辑主语为句子的主语it即thesystem,和本空人称一致，故本空应用反身代词itself

作宾语，代替语境中的“预警系统本身”。

10.tobecompleted考查不定式。句意：该系统由中国应急管理部监管，预计将于2022

年完工。根据句中时间状语“in2022”可知，这里用不定式的一般式表示将来要进行的动作，

且句中主语，4Thesystem”与“complete”之间为被动关系，故本空应用不定式的被动结构tobe

completed.,
