A.four thousand three hundreds and ninety-two B.four thousand three hundred ninety-two C.forty thousand three hundred and ninety-two D.forty thousand and three hundred and ninety-two 【答案】C 【详解】句意:40,392这个数字怎么读? 考查数字读法。英语中没有“万”这个单位,4万,应该用forty thousand表示,千位和百位之间不用and连接,但百位和十位之间需要用and连接,故选C。 2.The number 4,158,019 can be read as _. A.four million one hundred and fifty-eight thousand and nineteen B.four millions one hundred fifty-eight thousands and nineteen C.four million one hundred fifty-eight thousands and nineteen D.four millions one hundreds and fifty-eight thousands and nineteen 【答案】A 【详解】句意:4,158,019这个数字可以读作四百一十五万八千零一十九。 考查基数词。million“百万”;thousand“千”。million和thousand前有具体数词时,不用复数形式。故排除BCD。故选A。 3.—How do you read the number 40, 391?—It’s _.

A.55567085 B.55056785 C.55506785 D.55560785 【答案】A 【详解】句意:“五千五百六十七万八十五”是55,567,085。 考查基数词。从右至左数,每三位数加一个逗号 (即以此把数目分为若干段),第一个逗号前的数为thousand (千),第二个逗号前的数为million (百万)。所以“Fifty-five million five hundred and sixty-seven thousand and eighty-five”可以写成55,567,085。故选A。 5.About _ families chose the island to travel during the summer holiday. A.hundreds of B.two hundred C.two hundreds D.hundred of 【答案】B 【详解】句意:大约有两百个家庭选择暑假期间在该岛旅行。 考查数词用法。hundreds of数百个,表概数;two hundred两百,表确数;two hundreds错误表达;hundred of错误表达。根据“About”可知,空处需具体的数字,故选B。 二、基数词表示数量 6.There are _ floors in the building and my home is on the _ floor. A.twenty; twelfth B.twenty; twelve C.twentieth; twelfth D.twentieth; twelve 【答案】A 【详解】句意:这栋楼有二十层,我家住在十二楼。 考查数词。根据“floors”可知第一个空表达的是数量,英语用基数词表达数量,所以第一空应填基数词twenty;再由“the ... floor”可知第二空表达的是“第十二层”,英语中表达顺序用序数词,且空格前有定冠词the修饰,所以第二空用序数词twelfth,故选A。 7.The school has _ floors, and my classroom is on the _ floor. A.five; fifth B.fifth; five C.five; five D.fifth; fifth 【答案】A 【详解】句意:学校有五层楼,我的教室在第五层。 考查数词。five五,基数词;fifth第五,序数词。根据“The school has…floors, and my classroom is on the…floor.”可知,第一个空需要填写楼层数量的基数词,第二个空需要填写序数词,修饰空后的名词,表示顺序。故选A。 8.My mother will be _ years old next week. I’m planning to make something special as her _ birthday gift. A.fortieth; fortieth B.forty; forty C.forty; fortieth D.fortieth; forty 【答案】C 【详解】句意:我妈妈下周就四十岁了。我打算做些特别的东西作为她的第四十个生日礼物。 考查数词用法。fortieth第四十,序数词;forty四十,基数词。第一空,根据“… years old”可知,此处是指四十岁,应用基数词表示数量,排除A和D;第二空,根据“her … birthday gift”可知,此处是指她的四十岁生日礼物,应用序数词表示顺序,排除B。故选C。 9.There are _ books on the desk and the _ book is about the history of Vairo. A.five; five B.fifth; fifth C.five; fifth D.fifth; five 【答案】C 【详解】句意:桌子上有五本书,而且第五本书是关于瓦伊罗的历史。 考查数词。five五,基数词;fifth第五,序数词。根据“books”可知,空处①需要数量词来修饰,因此five符合句意;根据“the…book is about the history of Vairo”可知,空处②指的是第五本书,需要序数词,因此fifth符合句意。故选C。 10.Tom, it is the _ time in _ days that you’ve been late for school. A.two; three B.second; three C.two; third D.second; third 【答案】B 【详解】句意:汤姆,这是你三天来第二次上学迟到了。 考查数词的表达。two二,基数词;three三,基数词;second第二,序数词;third第三,序数词。结合“the…time”及语境可知,此处time表示“次数”,为可数名词单数,应用序数词second“第二”与之搭配;再结合“in…days”及语境可知,此处days表示“天”,为可数名词复数,应用基数词three“三”与之搭配,表示“三天”。故选B。 三、时间表达法 11.How do you say “9: 50” in English?

A.half past six B.six thirty C.Both A and B D.A or B 【答案】C 【详解】句意:——现在几点了?——现在是六点半。 考查时间表达法。half past six六点半;six thirty六点半;Both A and B意为“A和B都正确”;A or B意为“A或者B”。英语中表示时间的“半点”的表达结构为“half past +小时数”,也可直接用基数词表示小时和分钟,因此“half past six”和“six thirty”这两种表达都可以。故选C。 14.I come to school at a quarter _ eight and we start the class at 8:00 a. m A.at B.past C.in D.to 【答案】D 【详解】句意:我七点四十五分到学校,我们早上八点开始上课。 考查介词辨析。at在;past超过;in在里面;to差。根据“we start the class at 8:00 a. m”可知早上八点开始上课,所以是七点四十五分到学校,此处是a quarter to eight表示“七点四十五分”。故选D。 15.—What time is it now?—Look at the clock. It’s _. A.a quarter past seven B.a quarter to seven C.a quarter to eight D.a quarter past eight 【答案】C 【详解】句意:——现在几点了?——看看时钟。现在七点四十五了。 考查时间的表达方法。a quarter past seven七点十五分;a quarter to seven六点四十五分;a quarter to eight七点四十五分;a quarter past eight八点十五分。根据图片可知,目前是七点四十五。故选C。 四、编号表达 16.—Which class is Andy in?—He is in _.

A.the three grade B.Grade Third C.Grade Three D.grade three 【答案】C 【详解】句意:杰克现在上三年级。 考查数字的用法。一般编号用“名词+基数词”表达,Grade Three“三年级”,注意首字母要大写,C项符合。故选C。 19.—Where are the students now? —They are in _.

B.Seventy-nine. C.Seventy nine. D.Seven Nine. 【答案】B 【详解】句意:——Sue,你的爷爷多大年纪了?——79岁。 考查数词的正确表达。根据英语数词的书写规则,79应写作 “seventy-nine”,中间需用连字符连接。故选B。 23.Jerry is an _ boy, but he can take good care of himself.

A.in his thirty B.in his thirties C.in the thirty D.in the thirties 【答案】B 【详解】句意:John在他三十多岁的时候开始自力更生。 考查年龄表达法。in his thirty错误表达;in his thirties在他三十多岁时;in the thirty错误表达;in the thirties在三十年代。根据“John began to make a living by himself”可知,此处用in his thirties,表示“在他三十多岁时”。故选B。 六、大数表达 26.More than ten _ tourists went to see the flower show on that day. A.thousand B.thousands C.thousands of D.thousand of 【答案】A 【详解】句意:那天,超过一万名游客去观看了花展。 考查thousand的用法。thousand千;thousands复数形式;thousands of成千上万的;thousand of表述错误。ten为基数词,意思是“十”,基数词后需跟thousand单数形式。thousands为复数形式,表示概括,不可与基数词连用;thousands of是固定短语,用来修饰可数名词复数,不可与基数词连用。故选A。 27.The sun is shining. _ people are lying on the beach.

A.Million B.Million of C.Millions D.Millions of 【答案】D 【详解】句意:每年有数百万游客来参观拙政园。 考查数词用法。Million百万;Million of错误表达;Millions of数百万以上的。根据“visitors come to visit Humble Administrator’s Garden every year.”可知,本句想要表达的是“每年有数百万游客来参观拙政园”。表示不确定的“数百万”时,通常使用“millions of”这一固定表达。故选D。 29.How do you read 6,425,200? A.Six million four hundred twenty-five thousand two hundreds. B.Six million four hundred and twenty-five thousand two hundred. C.Six millions four hundred twenty-five thousand two hundred.
