新課備課備考 | 英語學科21世紀教育網(www.21cnjy.com)21世紀教育網(www.21cnjy.com)參考答案及試題解析1.C【解析】句意:東江湖是一個好玩的地方,成百上千的游客夏天去那里露營。考查大數表達。hundred“百”,可用“基數詞+hundred”指具體的數量,也可用hundreds of“數百”表示約數,空前無具體數字,用hundreds of。故選C。2.C【解析】句意:她的新連衣裙200元。考查價格表達。hundred與基數詞連用時,不加s。“yuan”是貨幣計量單位,不可數。故選C。3.C【解析】句意:長城非常有名,以至于每年都有數百萬的人來參觀。考查數詞用法。million前面有具體數詞時,不能加s,也不和of連用,表示泛指時用millions of,表示“好幾百萬的”。million of和two millions形式錯誤,可排除;millions of數百萬的,符合語境。故選C。4.A【解析】句意:——你能讀出數字10,307,115嗎?——是的,我能。它讀作一千零三十萬七千一百一十五。考查數字的讀法。按照英語數字的讀法規則,大數通常是從左到右,每三位數用逗號分隔,分別對應million、thousand等單位。該數字第一個逗號左邊是10,也就是million的部分,接下來是307,屬于thousand的部分,最后是115,是基本的百位數;一般來說,在百位和十位、個位之間要加“and”;此外,當hundred、thousand、million等詞前面有具體數字時,這些詞本身不需要加s。故選A。5.B【解析】句意:西藏每年一月到四月接收數以千計的游客。考查數詞。thousand前有基數詞時,用“基數詞+thousand原形”,前無基數詞時用thousands of表示“數以千計的”。故選B。6.C【解析】句意:在我們市博物館里,有許多兩千年前的古物在展覽。考查thousand的用法。thousand表示概數時,前面沒有具體的數字修飾,要用thousands of結構,如果前面有具體的數字修飾,thousand要用單數形式,其后不能加of,空前有two修飾,故選C。7.B【解析】句意:山洞里有成千上萬只蝙蝠。考查數詞的用法。當thousand有具體的數字時,用單數形式,且不與of連用;前面沒有具體數字時,使用thousands of表示“成千上萬的”。空前沒有具體的數字,所以此處用thousands of表示約數。故選B。8.A【解析】句意:他們有五百本書。它們都是新的。考查數詞表達。空前有five修飾,hundred不能用復數形式,其后也不加of,排除C/D選項;后接復數名詞,故選A。9.B【解析】句意:我們年級的學生大約有三百人。考查hundred用法。當hundred前有具體數詞時,hundred用單數形式,后不用介詞of;當hundred前沒有具體數字時,要加s加of;hundreds of“成百上千的”,不指確數,故選B。10.A【解析】句意:很多人去看電影《熱辣滾燙》。其中大約五千人是年輕人。考查數詞。Millions of成千上萬的……;five thousand五千。當hundred/thousand/million 等詞前無確切數字時,其后要加“s”,而且要和of連用,表示不確切的數目,故排除B、D兩項;當hundred/ thousand/million等詞前有確切數字時,其后不加“s”,直接修飾可數名詞復數形式或of+代詞復數形式。故選A。11.B【解析】句意:據說世界上三分之二的水被污染了。考查分數的表達和主謂一致。分數的表達:分子用基數詞,分母用序數詞,分子大于一,分母加s,因此第一空two thirds符合句意;結合“the water”是不可數名詞,謂語動詞用is。故選B。12.D【解析】句意:珠穆朗瑪峰是世界上最高的山峰。它有8000多米高。考查大數表達。如果thousand前面有數字,就用“數字+thousand”,表確切數字。thousands of“成千上萬的”,表概數。根據空前有具體數字,可知用thousand。故選D。13.C【解析】句意:——中國是一個有著約五千年歷史的偉大國家。——是的。每年都有成千上萬的外國人來參觀。考查數詞。根據第一空前“five”可知,與具體數字連用時,表示大數的單詞通常不加s,所以第一空用thousand,排除選項B和D。結合答句語境可知,當大數表示不確定的泛指時,則不僅要加s且要后接of,這樣才能接名詞,構成“thousands of成千上萬”。故選C。14.C【解析】句意:——各國之間的“貿易戰”已成為當今最熱門的話題之一。——是的,它每天收到數以千計的互聯網點擊。考查數字表達法。表示具體數字時,thousand要用單數,后面不能接介詞of;表示概數時,thousand要用復數,后接of,即thousands of,表示“成千上萬的”。此處應該表示一個概數,表示“成千上萬的”;故選C。15.C【解析】句意:我們都知道冬天有成千上萬的鳥飛到洞庭湖。考查數詞的用法。million百萬;millions of成百上千萬。英語中數詞hundred、thousand、million在表示具體數字時,不用復數形式;當與of連用表示一個多而不具體的數字時加s。根據“birds”可知,此處表示多而不具體的數字,用millions of。故選C。16.C【解析】句意:上世紀30年代,數百萬烏克蘭人餓死或被驅逐出境。考查million的用法。數詞million有兩種用法:1.基數詞+million,表示“幾百萬”;2.millions of“數百萬”,表示概數。結合選項,故選C。17.B【解析】句意:據說世界上三分之二的水被污染了。考查分數表達及被動語態。分數表達中分子用基數詞,分母用序數詞,當分子大于一時,分數要變為復數。表示“三分之二”要用two thirds,排除C;主語water與動詞之間是被動關系,應該用被動語態be done,表示“被污染”用be polluted,此處是一般現在時的被動語態,可排除A和D,故選B。18.D【解析】句意:這個小鎮非常有名,每年夏天都有成千上萬的游客來這里。考查數詞的表達。表示具體的數量,要用基數詞+數詞的單數形式;表示概數,用數詞的復數形式+of,四個選項中只有D選項表達正確,故選D。19.A【解析】句意:那天,超過一萬名游客去觀看了花展。考查thousand的用法。thousand千;thousands復數形式;thousands of成千上萬的;thousand of表述錯誤。ten為基數詞,意思是“十”,基數詞后需跟thousand單數形式。thousands為復數形式,表示概括,不可與基數詞連用;thousands of是固定短語,用來修飾可數名詞復數,不可與基數詞連用。故選A。20.A【解析】句意:在我們學校五分之三的學生是男生。考查分數表達和主謂一致。分數表達法為“分子基數詞,分母序數詞,分子大于一時,分母要加s”,所以“五分之三”的正確表達為“three fifths”;“分數+of+名詞”作主語時,謂語動詞的形式要和該名詞保持一致,此處名詞students是復數,be動詞要用are,故選A。21.A【解析】句意:我們學校有數百名學生。考查大數的表達。當hundred與數詞連用時,表示一個具體的數字,后面不加s;當hundred與of+復數名詞連用時,表示一個多而不具體的數字,后面加s。 根據“students”可知,設空處前沒有數字,此處表示不確定數量的大概數目,hundreds of “數百”符合題意。故選A。22.A【解析】句意:你是如何正確地讀出8,465,700這個數字的?考查數字的讀法。hundred,hundred和million等表示單位的數量詞前有具體數字時,這些詞不能加s,排除CD;百位和十位之間加and,其余不加and,排除B。故選A。23.D【解析】句意:這里的環境變得越來越好。成百上千的鳥回來了。考查數詞用法。Hundred百;Hundreds of成百上千。當表示不確定數目時,其結構是“hundreds of+名詞復數”;但表示確定數目時,其結構是“基數詞+hundred+名詞復數”。結合題干這里沒有指明有多少只鳥回來,四個選項中只有D選項表達正確,Hundreds of birds表示“成百上千的鳥”,故選D。24.D【解析】句意:到去年年底為止,我們已經種植了大約500棵樹。考查數詞的表達。當hundred前有明確的數詞時,后面不加s,也不加of;當它不與具體數字連用,而是表示不確定的泛指數時,則不僅要加復數詞尾s,而且要后接介詞of,然后才能接名詞。故選D。25.A【解析】句意:——這臺新車多少錢?——大約八萬元。考查數詞的表達。根據“eighty”可知,此處表示確切的數量,應填thousand的單數形式,故選A。26.A【解析】句意:——南京真是個好地方,不是嗎?——是的,每天有成千上萬的游客來這里旅游。考查數詞的用法。thousand意為“千”。和具體數字連用時,不加s;前面沒有具體數字,表示不確切的數量時,用“thousands of+名詞復數”,意思是“成千上萬的”。故選A。27.C【解析】句意:大約有成千上萬的人在海灘上享受日光浴。考查大數的表達。hundred/thousand前有具體數字時,hundred/thousand后不加s、不加of;hundred/thousand前沒有具體數字時,hundred/thousand后加s、加of。故選C。28.C【解析】句意:暑假期間,數以百萬計的人參觀長城。考查大數的表達。million可用“基數詞+million”或“millions of”來修飾其后的名詞,故選C。29.D【解析】句意:——我們鎮上的人在植樹節那天種了數百棵樹。——干得好!每個人都可以做些事情讓我們的城市變得更綠色。考查hundred用法。空前沒有具體的數字,是概數的表達,應用hundreds of“數百”表示,故選D。30.C【解析】句意:成千上萬的人在春節來到這里。考查大數的表達。thousand與具體數字連用時,其后通常不加s,后面也不跟介詞 of;當thousand不與具體數字連用,表示概數時,其后不僅要加s,而且要后跟介詞of;當thousand與many連用時,其后帶不帶s 均可,但是若不帶s,后面的介詞of可以省略,若帶s,則后面的介詞of不能省略;空前無具體數字,此處需用短語Thousands of。故選C。31.D【解析】句意:它在右側大約500米處。考查數詞hundred的用法。“基數詞+hundred”表示具體數字;metre“米”,可數名詞,根據“5…”可知,此處應用其復數形式。故選D。32.A【解析】句意:我們學校有大約三千名學生。考查數詞的用法。表示確切數量:基數詞+thousand;表示模糊數量:thousands of +名詞。結合本題的分析可知,只有選項A符合。故選A。33.A【解析】句意:今年的6月2日,成千上萬的人在東花江附近慶祝端午節。令我們感到高興的是,幾乎沒有垃圾留下來。考查大數表達。表達具體數字,thousand等數詞單位后不加s不加of;表達不具體數字,數字單位后加s加of。空處為不具體數字,需加s加of。故選A。34.C【解析】句意:大廳里有數百人。他們正在開會。考查大數的表達。hundred前無具體數詞,則hundred要用復數形式,且在名詞前要加of;若hundred前有具體數詞,則hundred用單數形式,與名詞之間無需加of。根據“There are...people in the hall.”可知,空前無數詞,空處應是hundreds of“數以百計的”。故選C。35.C【解析】句意:每年在五一的時候有成千上萬的游客參觀這個島。考查基數詞。thousand與具體數詞連用時,要用單數形式,后面不能加of;thousand與of連用時要用復數形式,即thousands of,意為“成千上萬的”,為固定用法。故選C。36.C【解析】句意:每年上百萬本書被捐獻給貧困地區的孩子們。考查數詞用法。million意為“百萬”,前有基數詞時,million用原形;millions of意為“上百萬的”,后接可數名詞復數。選項BD形式錯誤,故排除;設空前面沒有基數詞,故選C。37.A【解析】句意:上周,五百名學生參加了我們學校的運動會。考查數詞。hundred百,其前加具體數字;thousands后常加of;hundreds of成百上千;thousands of成千上萬。“five”是具體數字,故選A。38.B【解析】句意:中國是世界上人口最多的國家,世界上大約五分之一的人生活在中國。考查形容詞最高級和分數的表達。lager形容詞large的比較級;one fifth五分之一;the largest形容詞large的最高級,最大的;largest形容詞large的最高級,前面有物主代詞或名詞所有格等情況時使用;one fifths表述錯誤;large大的,形容詞原級。根據第一空前后has和in the world可知,中國在世界上人口最多,所以這里用最高級the largest。第二空是分數的表達:分子用基數詞,分母用序數詞(如果分子大于一,分母序數詞用復數),所以“五分之一”是one fifth,排除選項C和D。故選B。39.B【解析】句意:圖書館里有數百種不同的書。考查數量表達。hundred表示“一百”,前面有具體數字時用單數形式,如two hundred(兩百);hundreds of表示“數百”,用于泛指數量多,前面不加具體數字。根據“different kinds of books”可知此處表示泛指“數百種”,故選B。40.D【解析】句意:——它是個美麗的地方嗎?——是的。它是成百上千只鳥兒的家園。考查數詞的用法。hundred意為“百”,表示某個確定的數量,與數字連用,應使用單數形式。表示某個不確定的數量,用復數形式,與of連用,hundreds of意為“成百上千的”。故選D。41.B【解析】句意:大約有兩百個家庭選擇暑假期間在該島旅行。考查數詞用法。hundreds of數百個,表概數;two hundred兩百,表確數;two hundreds錯誤表達;hundred of錯誤表達。根據“About”可知,空處需具體的數字,故選B。42.D【解析】句意:根據一項調查,五分之四的女性在家做家務,但只有五分之二的男性愿意這樣做。考查分數表達。根據空前的but only可知此處表示做家務的男人數量比女性少,分數應該比五分之四小,排除AB;結合選項可知,“五分之二”符合題意。在英語中表達分數時,分子用基數詞,分母用序數詞。如果分子大于1,分母要用復數形式。故選D。43.B【解析】句意:6,425,200這個數字怎么讀?考查數字的讀法。數字的讀數均為基數詞,從右往左,第一個逗號讀成thousand,第二個逗號讀成million;且hundred,thousand,million前面有具體數字,不加s;百位數和十位數之間用and 連接。故選B。44.B【解析】句意:西藏每年從一月到四月接待成千上萬的外國游客。考查大數表達。thousand“千”,前面有具體數字時,不加s,不加of;當后面加s時,需要和of連用。結合選項,故選B。45.B【解析】句意:南湖公園真是個好地方。成千上萬的人在春天去那里放風箏。考查thousand的用法。thousand一般不單獨使用,與具體數字連用時需用其單數形式;與介詞of連用時需用其復數形式,前面不用具體數字,thousands of表示“數以千計的;成千上萬的”,分析選項可知,B選項表達正確。故選B。46.D【解析】句意:這個城市五分之二的土地被樹木和草覆蓋著。考查分數表達方式。分數表達方法: 基數詞+ 序數詞,基數詞作分子,序數詞做分母, 如果分子(基數詞)是大于1,分母(序數詞)要變成復數,表示“五分之二”用two fifths。故選D。47.C【解析】句意:他的作品有四分之三是在五十幾歲時寫的。考查數詞。分數的表達:當分子大于一時,分母加s,排除B選項。分析和分母之間的表達不加連字符,排除A選項。fifties五十幾;fiftieth第五十;表示某人幾十多歲這樣的約略年齡,用“in one’s+逢十的基數詞的復數(如tens, twenties, thirties等)”來表達。in one’s fifties在某人五十幾歲時,故選C。48.C【解析】句意:每年,數以百萬計的外國人來中國旅游。考查數詞的用法。million“百萬”,表示具體數字時,million前有基數詞,且million不用復數形式;表示不具體數字時,million變復數,且與of連用。由“Every year, ... foreigners come to visit China.”可知,此處表示不具體數字,應用millions of,表示“數以百萬計的”,故選C。49.B【解析】句意:——Jack,現在中國的人口是多少?——讓我想想。大約是14億。考查特殊疑問句以及常識。固定句式:what is the population

of“數以百計的”;第二空前有基數詞five,因此第二空是單數形式hundred。故選C。51.A【解析】句意:長城太壯觀了,所以成千上萬的人來這里參觀。考查基數詞的表達。表示概數時候,應用短語thousands of表示“上千的”,表示具體數字的時候,應用基數詞+thousand,表示“幾千”。故選A。52.B【解析】句意:——你的工作進展如何?——我們已經完成了五分之二。考查分數表達。英語表達分數時,分子為基數詞,分母為序數詞,分子大于1,分母加-s,所以五分之二表達為two fifths,故選B。53.A【解析】句意:馬克,一個十三歲的男孩,是一名優秀的電腦程序員。他制作了一個應用軟件,許多學生用它學英語單詞。考查hundred的用法。hundred前面有具體數字表確切數目時不能加-s;表示不確切的數目時,強調數量之多,要用復數形式,且與of連用。空前無數詞,此處用結構hundreds of。故選A。54.C【解析】句意:看!農場里有數百頭牛。考查基數詞的用法。hundred“百”,表示具體數字時,與基數詞連用,且不用復數形式;表示概數時,hundred要變復數,且與of連用。根據“Look!
