参考答案:
1.D
短语be good for意为“对…有益”,短语be good at意为“擅长于…”,healthy是形容词“健康的”,health是名词“健康”,这里是说“对健康有益”,故选D。
2.D
考查不定式作宾补和名词的格。ask sb to do sth表示“要求某人做某事”,不定式作宾语补足语。第二个空是名词of所有格,“名词+of+名词”表示所有关系,此处表示“鱼翅的销售”。故选D。
3.B
考查现在完成时。A选项为第三人称的现在完成时;B选项为第一、二人称的现在完成时;C和D非正确形式。此处表示现在为止的生活经历,用现在完成时。主谓一致,主语是you,因此完成时用have you heard表示。故选B。
4.B
考查固定搭配和情态动词用法。lead导致,动词原形;leads第三人称单数形式;lead to通向;leading to动词ing 形式。and连接两个并列的成分,can为情态动词,后接动词原形,因此and后也是动词原形。lead to固定搭配,表示“通向”。故选B。
5.A
考查状语从句。drop下降,动词原形;drops第三人称单数形式;bring带来,动词原形;will bring将带来,一般将来时。此句为if引导的条件状语从句,主句一般将来时,从句用一般现在时代替一般将来时。并且从句主语their numbers为复数形式,谓语动词用drop。
6.A
考查动词辨析。cost花费;take花费;拿;pay付款;花费;spend花费。四个词均有“花费”的意思。spend和pay的主语通常为人,故排除C和D。take一般指“花费时间”,此处anything表示“任何事”,并没有说是时间,排除B。cost用法sth. cost sb. + 时间/金钱/力气。故选A。
7.A
A.to drink喝,动词不定式; B.drank喝,过去式; C.to drinking不定式符号to后应使用动词原形,故该选项形式错误; D.drink动词原形。本题考查stop后跟动词不定式的用法。stop是及物动词,后跟动词不定式,指“停下手中的事去做某事”,是固定搭配。故选A。
8.C
A.有帮助的;B.有用的;C.有害的;D.有希望的,这里是说要远离游戏,肯定是因为游戏有害青少年,be harmful to…意为“对…有害”,故选C。
9.C
A.或者…或者…;B.既不…也不…;C.不仅…而且…;D….和…都…。从答句可以看出麦克和他兄弟都是认为这样的方式是有益的,所以他们两个都是骑车去上班的,排除AB,both…and连接两个主语的时候谓语动词用复数形式,Not only…but also连接主语的时候谓语动词参照后一个连接的主语,这句话中的谓语动词是rides,用了三单形式,说明不是采用both…and结构,而是Not only…but also结构,故选C。
10.C
考查感叹句辨析题。英语中感叹句有两种形式:1.what引导的感叹句,其构成:what+a/an+形容词+可数名词单数+主语+谓语!/ what +形容词+可数名词复数+主语+谓语!/ what +形容词+不可数名词复数+主语+谓语! 2. How引导的感叹句,其构成:how+形容词/副词+主语+谓语!本句中fast快速地,是副词;the time flies在主谓结构。结合句意和语境可知选C。
11.B
考查情态动词辨析题。must/have to必须,should应该,can可以。按照英美的语言习惯,由must引起的一般疑问句,其肯定回答用must,意思是“必须,一定”;而否定回答则用needn’t,表示“不需要”,或者用don’t have to表示“没必要”。根据句意和语境,可知选B。
12.C
考查被动语态。主语the club是动词organize的承受者,需用被动语态,即be+过去分词;又因为the club是第三人称单数,be动词需用is。故选C。
13.C
comfortable舒服的;relaxed放松的;harmful有害的;useful有用的。be harmful to对….有害,是一个固定短语。根据句意可知应选C。
14.D
本题考查短语辨析。give back“归还”;get back“回来;取回”;go back“回去”;bring back“恢复;唤起,想起”,根据所给空前面的the photo“照片”以及后面的her memories“她的记忆”可知,唤起符合语境,故答案选D。
15.C
根据“比较级+and+比较级”表示“越来越……”,为固定用法,可排除A、B两项;由常识可知,春天到来后,白天会变得越来越长,故答案选C。
【点睛】形容词比较级的用法:1、修饰比较级的词有even、far、much、a little等;2、比较级+and+比较级表示“越来越”;3、the+比较级……,the+比较级……表示“越……,就越……”;4、否定词+比较级表示“最高级含义”。
例如题目中考的是“比较级+and+比较级”表示“越来越……”,所以选的是longer and longer。
16.A
考查动词短语。A. pulled down意为“拆毁";B. put down意为“放下”;C. turned down意为“调小”;D. let down意为“使……沮丧”。根据Where did you get these old doors?结合From the old houses which were _____ by the workers.可知意思是说从被工人拆掉的旧房子里得到的这些旧门,所以此处表达的意思应是“拆毁”,故答案选A。
17.B
考查一般现在时的被动语态。A. polluted一般过去时;B. is polluted一般现在时的被动语态;C. is polluting现在进行时;D. have been polluted现在完成时的被动语态。根据题干可知,从句主语the river是动作pollute的承受者,所以要用被动语态,排除A、C两项;由主句的谓语动词die可知句子时态用一般现在时,排除D选项;一般现在时的被动语态结构为am/is/are+动词的过去分词,主语the river是第三人称单数,所以be动词用is,pollute的过去分词是polluted;故答案选B。
18.D
考查一般现在时及动词非谓语。由句意可知句子时态用一般现在时,第一个空,主语My aunt为第三人称单数形式,所以谓语动词用第三人称单数opens;第二个空,设空处作后置定语修饰前面的名词shop,所以用现在分词selling,selling recycled things出售回收物品;故答案选D。
19.C
考查固定句型。importance重要,名词;important重要的,形容词。根据题干可知本题考查固定句型:It's+形容词+for sb.+to do sth.意为“做某事对某人来说是……的”,所以第一个空,应填形容词important,第二个空,定冠词the用于名词前,所以应填名词importance,the importance of recycling回收利用的重要性;故答案选C。
20.C
cut down意思是砍倒,A选项是过去时,B选项是现在完成时(但是句子主语是复数,而此选项谓语动词是单数),故B选项排除;have been cutting down是现在完成进行时,它表示发生在过去的动作,一直持续到现在,并有可能继续持续下去,此时和现在完成时表达的意义一样,D选项是现在进行时。根据时间状语in recent years及句意可知,砍树这个动作发生在过去,并一直持续到现在,并可能会一直持续下去,结合选项故选C。
21.A
只需要20分钟,比坐出租车花费更少。故选A。主语是it,表示花费时间用take,花费金钱用cost;spend的主语必须是人,故选A。
22.D
考查介词辨析。be made up of“由……组成,由……构成”;make from“用……制成”,看不出原材料;make… into“把……做成,把……转变为”,make后面跟原材料,into后面跟制成品;make...out of“用……制造出,用……制成……”,make后面跟制成品,out of后面跟原材料。some iron是能看出材料的,故不用from,some iron是原材料,故不用into。故选D。
23.D
考查动词短语辨析。cut down“砍倒;减少”;pull down“拆下;摧毁”;turn down“调低;拒绝”。由上句句意“这座旧房子很危险”可知,此处表示“它必须尽快被拆掉”,故排除A和C两项;it(the old house)与谓语pull down为被动关系,谓语动词应用过去分词,故选D。
24.B
A. went into进入,一般过去时;B. go into进入,动词原形;C. was going into正在进入,过去进行时;D. came out of出来,一般过去时。notice是感官动词,在主动语态中后面用不带to的不定式作宾语补足语。故选B。
25.C
考查动词短语辨析。take out去除;take off关掉;take part in参加;take care of照顾。“参加某项活动”用词组take part in 表达。其它短语意义与句意不符,故选C。
26.A
考查动词短语和动词时态用法。hear of指偶尔听说;hear from收到某人的来信;hear about得知。根据第二句and后面的knew是一般过去时可知,第二空是一般过去时,排除C;短语hear from意为收到某人来信,故选A。
27.C
考查动词时态用法。固定搭配there used to be sth.意为过去曾经有某物,现在没有了;根据句意第二空用现在完成时have become,故选C。
28.C
考查动词短语和时态辨析。used to do sth.意为“过去常做某事”,其否定形式为didn't use to do… 意为“过去不做某事”。be used to doing sth.意为“习惯于做某事”;be used to do sth.意为“被用来做某事”,它们的否定形式在be动词后加not。由前句I'm surprised to see you smoking.可推知对方过去不吸烟。根据句意语境,可知选C。
29.B
考查主谓一致和副词辨析。the number of:…的数量,of后面跟可数名词复数,做主语时谓语动词使用单数,可排除A和C。little:小的,几乎没有,很少,形容词和副词,一般修饰名词或形容词;low:低,低下地,低的,形容词和副词。修饰drop只能使用low,drop too low:下降得太低;结合句意和选项可知选B。
30.D 本题主要考查the number of和a number of之间的区别。The number of译为“……的数量”,当它作主语时,谓语动词用单数形式;a number of译为“大量的”,当它作主语时,谓语动词用复数。本题中,第一空表示“……的数量”,第二空表示“大量的”,故选D。
