until she had arrived home_her appointment with the doctor.adid she remember bthat she rememberedcwhen she remembered dhad she remembered解析此句为强调句型,基本结构为 it is /was 被强调部分that其他成分。该句中是对not until.句型进行强调。答案b2all the employees except the manager_to work online at home.aencourages bencouragecis encouraged dare encouraged解析考查动词的一般现在时与语态问题以及主谓一致原则。主语为all the employees,而except the manager为介词短语,不影响主语与谓语关系,即谓语动词应用复数形式,排除a项和c项;又因 all the employees 与encourage之间为被动关系,故选d项。答案d3if your race car isnt insured,you may_losing everything when it hits something solid.adelay bdeny cavoid drisk解析句意:如果你的赛车不入保险的话,当它撞了硬物后,你可能会一无所有。risk doing sth冒着做某事的危险,符合题意。答案d4_i ask you something if you are not too busy?yes,of course you_.ashould;should bcould;canccould;could dcan;could解析考查情态动词。could 用于疑问句中,表示有礼貌的请求,不表示时态,因此回答时用can。答案b5_the poem a second time,the meaning will become clearer to you.ayour reading bwhile readingcif reading dwhen you read解析read的主语和become的主语不一致,所以应用从句。答案d6the newcomers found it impossible to_themselves to the climate sufficiently to make permanent homes in the new country.asuit badapt cregulate drelate解析adapt oneself to使自己适应;suit(1)合某人意;(2)衣服款式(色彩)适合某人;(3)使适合于(口味、兴趣、工作);regulate v(用法律)掌管;控制(机器、设备);调节;relate.to把联系到一起。答案b7the bomb exploded,_victims in the building.atrapped btrappingcbeing trapped dhaving trapped解析句意:炸弹爆炸了,受害者被困在大楼里。现在分词作结果状语,“trap sb in.”。答案b8it is wellknown that advertising is often the most effective method of_.amotivation bextensionccontribution dpromotion解析promotion表示“推销;促销活动”,为不可数名词。句意:大家都知道广告是最有效的促销方法。motivation动机;extension延长,扩充;contribution贡献。答案d9to keep market prices steady,the government should first keep demand and supply_.astocked bpreserved cprovided dbalanced解析keep demand and supply后面需要一个形容词作宾语补足语,balanced意为“平衡的”。句意:为了使市场价格稳定,政府首先应该使供需平衡。stock进货,采购;preserve 保护,维持;provide提供。答案d10one of the important factors in determining whether you get good grades is your_of mind.acondition bstate ccase dsituation解析state在这里表示“状态;状况”。句意:决定你是否能够取得好成绩的重要因素之一是你的思想状态。答案b11he was_being killed yesterday.a car passed him at what he thought was a dangerous speed.aused to bgoing to cup to dclose to 解析close to表示“接近于,几乎”。句意:昨天他几乎死掉了。一辆小汽车以他认为很危险的速度从他旁边擦肩而过。答案d12young as she is,the girl_because she won the first prize in the super girls

cbecame;is dis becoming;is解析the rich表示“富人”,作主语时看作复数。后面which is a social problem是非限制性定语从句,其中which指代的是前面的这个现象,所以看作单数。答案b15it is_that so many young athletes are coming into the team.aencouraging bdiscouragingcencouraged ddiscouraged解析由句意推断“如此多的年轻运动员加入进来”应该是“令人鼓舞的”。答案a.完形填空antarctica is the continent which is the most southern area of land on the earth and is mostly_1_with ice.this is one of the driest and_2_in the world.but people from all over the world come to_3_there.near the south pole,three thousand people live together in a place_4_amundsenscott station.the

continent!”1a.filled bfullcdiscovered dcovered解析 be covered with由覆盖。答案d2a.warm areas bcoldest placesccool areas dhottest places 解析由常识可知,南极洲气温很低,所以是coldest places。答案b3a.travel bsettle cwork dlive解析由第五段可知,生活在这儿的人大部分是科学家,他们研究,可以推出此空应为“工作”。答案c4a.called bcall ccalls dcalling解析called为过去分词做定语。答案a5a.built bhas cexists dlies解析exist和lie是不及物动词,后不加宾语,故排除;build应为被动,所以选b。答案b6a.telephone bfilmctelevision drecord player解析根据句中的have a conversation with someone可以选出答案。答案a7a.other banother cthe other dothers解析此处用作定语来修饰place,place为单数,可用another或the other来修饰。another为“另一个”;the other为“(两个中的)另一个”。答案b8a.printers biconscmice dcomputers解析破折号有解释说明的作用。此处由后面的electronic machines that store information and use programs to help them find,organize,or change the information可知作者指的是电脑。printer打印机;icon图标;mice(mouse的复数形式)鼠标。答案d9a.dont bmustntcneednt dshouldnt 解析由下文because th
