第二部分基础知识运用（共30小题，计40分）

一、选择填空（共15小题；计20分）

A.从以下各题的A、B、C三个选项中选择正确答案。（共10小题；每题1分，计10分）

（）1.—Lily,doyouknow?

一Attenthisevening.

A.whenwasJohnborn

B.howlongtheconcertwilllast

C.whattimeAlicewillarrive

D.iftheywillattendthemeeting

［答案］c

［详解］核心短语/词汇:when（什么时候）;howlong（多长时间）;whattime（几点）;if（是否）向意:----多

里斯，你知不知道爱丽丝几点到?——今晚十点。根据答句可知“今晚十点”是一个时间点，而how

long是提问时间段的，排除B;if是提问是否的，排除Dewhen（什么时候）、whaltime（几点）都可以

提问时间，但宾语从句中句子要用陈述句语序，A中be动词提前了，是疑问句语序，所以选择C.

（）2.Theyouare,thefewermistakesyou'llmake.

A.carefulB.morecarelessC.morecareful

［答案］B

［详解］careful,careless;The+比较级……lhe+比较级;句意:在考试中，你越细心，你犯的错误就越少。固

定句式themore,themore越.....越.…前后都用比较级。故选B。固定句式的考查也是英语考查的一个

重点，熟记这些句式可以减少答题中的分析判断时间，所以平时加强句式记忆也是学好英语的关键

环节。

（）3.—Excuseme!Doyouknow?

—It'sontheSecondStreet.

A.whereisthesupermarket

B.whendoesthesupermarketopen

C.wherethesupermarketis

［答案］c

［详解］一打扰一下!你知道超市在哪里吗？

一在第二条街上。

考查宾语从句，A超市在哪里；B超市什么时候开门；C超市在哪里;根据题干"Doyouknow...?”和选

项可知，此题考查宾语从句，宾语从句三要素:语序，时态;引导词，宾语从句要用陈述句语序，选项

AB为疑问句语序，排除。故选C。

()4.Themothertoldherchildrentoelectricity.Itisdangerous.

A.makefriendswith

B.stayawayfrom

C.begoodat

［答案］B

［解析］句意:这位母亲告诉她的孩子们远离电。这很危险。makefriendswith.....交朋友；stayawayfrom

远离；begoodat擅长。根据Itisdangerous.可知,这位母亲告诉她的孩子们远离电。故选B。

()5.Mr.Greenstillwenttothemeetinghehadabadcold.

A.becauseB.unlessC.though

［答案］C

［解析I句意:尽管得了重感冒，格林先生还是去参加了会议。because因为；unless除非;though尽管。

根据填空处前后的内容可知，此句是(hough弓卜导的让步状语从句。意思是“尽管”。故选C。

()6.WhydoesTinalooksotoday?

一She'swonthefirstprizeintheEnglishcontest.

A.happyB.happierC.happiestD.happily

［答案］A

［解析］句意：一蒂娜今天怎么这么高兴？一她在英语竞赛中得了一等奖。happy幸福的；happier更

快乐的;happiest最幸福的;happily高兴地。look+adj构成“感官动词+形容词"，即“系表结构”。

”so+adj.原级”，意为“如此…。”故答案选A。

()7.MysisterseldomspendstimeonTVorcomputeratweekendsbecausereadingmostofher

freetime.

A.takesonB.takesupC.takesawayD.takesoff

［答案］A

［解析］Sandy周末很少外出，因为读书占用了她大部分的空闲时间。本题主要考查动词词组。

A项，takeup"拿起；开始从事;占据"。B项，lakeon”承担；呈现;具有;流行;接纳;雇用;穿上”.C项，

takeoff，起飞;脱下;离开;突然成功“。D项，takeout”取出；去掉;出发;发泄根据句中Sandyseldom

goesoutatweekends和because可知，because后的句子是在解释Sandy周末很少外出的原因，因此

此处表示的是:读书占用(takeup)了她大部分的空闲时间。故正确答案为A。

()8.—WhatwasyourlittlesisterdoingwhenIcalledyouyesterday?

—Sheforlosingagame.

A.criedB.iscryingC.wascrying

［答案］D

［解析］考查动词时态。句意:——昨天我打电话给你时你妹妹在干什么?一一她为输掉一场比赛而哭

泣。根据问句中"was...doing”可知答句应用过去进行时回答，主语she为第三人称单数，所以用was,

后接动词现在分词crying。A项用于一般现在时下主语为第三人称单数时，B项为动词过去式和过

去分词，C项用于现在进行时下主语为第三人称单数时。故答案为D。

()9.FollowtheP.Eteachers'instructions,___youmaygethurtwhenexercising.

A.soB.orC.but

［答案］B

［解析］

考查连词辨析。句意:按照老师的指示去做，否则你在运动时可能会受伤。A.所以;B.否则;C.但是;D.

并且。根据前后句句意和逻辑关系可知，这里应该为。r引导的并列句。故选B。

()10.Thechildrengotexcitedwhentheyheardthegood.

［答案］news

［解析］句意:听到这个好消息，孩子们很兴奋。形容词修饰名词，根据Thechildrengotexcited，结合首字

母提示，可知news，消息，符合题意,好消息让孩子们兴奋，故答案为news.

尽可能多的病毒。我们可以用抗生素杀死细菌，但无法杀死病毒，任何药物对病毒的感染都是无效的，

它只能通过自身的免疫能力来保护自己。
