Unit 1 Home 基数词和序数词 （时间：60分钟，满分：100分） 一、单项选择(本大题共30小题，每小题2分，共60分) 1．—Your son is so smart. How old is he? —________. We had a special party for his ________ birthday last night. A．Nine; nine B．Ninth; nine C．Nine; ninth D．Ninth; ninth 【答案】C 【详解】句意：——你的儿子真聪明。他多大了？——九岁。昨晚我们为他的九岁生日举办了一个特别的派对。 考查数词。nine九，基数词；ninth第九，序数词。根据“How old is he?”可知，第一空回答年龄，用基数词；根据“his...birthday”可知，第二空表达“第九个生日”，用序数词。故选C。 2．There are ________ months in a year. December is the ________ month. A．twelve; twelve B．twelve; twelfth C．twelfth; twelve D．twelfth; twelfth 【答案】B 【详解】句意：一年有十二个月。十二月是第十二个月。 考查数词。twelve十二，基数词；twelfth第十二，序数词。根据“months in a year”可知，空一处是指一年有十二个月，用基数词表示数量；根据“the ... month”可知，空二处表示第十二个月，用序数词表示顺序。故选B。 3．Our hometown, Harbin, attracts (吸引) ________ tourists from all over the world in winter. A．thousand of B．thousands of C．two thousands 【答案】B 【详解】句意：我们的家乡哈尔滨在冬天吸引了来自世界各地的成千上万的游客。 考查数词用法。thousand of错误搭配；thousands of成千上万的；two thousands错误搭配。当表示概数“成千上万”时，应用“thousands of”，且thousand后不加s时需与具体数字连用。此处为泛指大量游客，无具体数字。故选B。 4．________ of people come to the park. A．Thousand B．Thousands C．Hundred D．Hundreds 【答案】B 【详解】句意：成千上万的人来到这个公园。 考查数量短语。Thousand千，单数；Thousands千，复数；Hundred百，单数；Hundreds百，复数。表示概数“数以千计的”应用短语“thousands of”，其中“thousands”用复数形式。故选B。 5．________ people came to celebrate the ________ birthday of the People’s Republic of China. A．Thousands of; seventy B．Thousands of; seventieth C．Five thousand of; seventy D．Five thousands; seventieth 【答案】B 【详解】句意：成千上万的人前来庆祝中华人民共和国第七十个生日。 考查大数表达和序数词。Thousands of成千上万的；seventy七十；seventieth第七十；Five thousand of错误表达。表示概数时，用“thousands of”，意为“成千上万的”，故第一空选Thousands of；表示“第七十个生日”应用序数词seventieth。选项A中seventy为基数词，C中five thousand后不能接of，D中thousands错误使用复数形式。故选B。 6．There are ________ students in the school. A．thousands of B．two thousands C．thousand of 【答案】A 【详解】句意：这所学校有数千名学生。 考查数词短语辨析。thousands of 数以千计的；two thousands 错误表达，thousand前面有具体数字时，不加s，thousand of 错误表达，应是thousands of。根据“students in the school”可知，此处表示学校有“数以千计的”学生。故选A。 7．—What’s seven and ________? —It’s twenty. A．eleven B．twelve C．thirteen 【答案】C 【详解】句意：——七加十三是多少？——是二十。 考查基数词辨析。eleven十一；twelve十二；thirteen十三。根据“It’s twenty”以及“seven and…”可知，此处是数字运算，20-7=13，空处应填thirteen。故选C。 8．There are ________ months in a year. Our National Day is in the ________ month of a year. A．twelve, ten B．twelfth; tenth C．twelve; tenth 【答案】C 【详解】句意：一年有十二个月。我们的国庆节是在每年的第十个月。 考查数词的用法。twelve十二，基数词；ten十，基数词；twelfth第十二，序数词；tenth第十，序数词。根据“There are…months”可知，此处表示数量，应用基数词twelve；根据“in the…month of a year”可知，此处表示顺序，应用序数词tenth。故选C。 9．—Lucy, how many girls are there in your class? —There are ________ students in ________ class. A．twenty, my B．twentieth mine C．twenty, mine 【答案】A 【详解】句意：——露西，你们班有多少女孩？——在我的班有二十个学生。 考查基数词和物主代词的用法。twenty二十，基数词；my我的，形容词性物主代词；twentieth第二十，序数词；mine我的，名词性物主代词。表示数量时用基数词，所以第一空用基数词；根据“class”可知，第二空用形容词性物主代词。故选A。 10．________ wild flowers color the mountains, especially in April and May. A．Millions of B．Million C．Two millions 【答案】A 【详解】句意：数百万的野花点缀着群山，尤其是在四五月份的时候。 考查million的用法。million前无具体数字时，需用复数形式millions，并搭配介词of，表示“数百万的”，用于修饰可数名词复数；单独使用million时，前面必须有具体数字 (如 one, two)，无论数字多大，million用单数形式。本题选项中，选项B，“Million”缺少具体数字，无法直接修饰名词；选项C，“Two millions”在具体数字后误用复数，不符合语法规则。故选A。 11．I can see _________ books on Mary’s desk, six science books and five music books. A．twelve B．eleven C．thirteen 【答案】B 【详解】句意：我能看到玛丽桌上有十一本书，六本科学书和五本音乐书。 考查数词及数字的计算。twelve十二；eleven十一；thirteen十三。根据“six science books and five music books”可知，书的总数为6+5=11本。故选B。 12．We planted ________ trees last year. Three ________ of them are in the park. A．thousands of; hundred B．thousand of; hundred C．thousands of; hundreds D．thousand of; hundreds 【答案】A 【详解】句意：去年我们种植了几千棵树，其中的三百棵在公园里。 考查数词。thousand是一个数量单位，千，它和具体的数词连用的时候，不用复数形式；或者构成短语thousands of表示约数，成千的。hundred是百，用法与thousand相同。结合选项可知，空一用thousands of表示“成千的”；由“Three”可知，空二表示具体的数字，不用复数。故选A。 13．There are ______ floors in the building. I live on the ______ floor. A．fifth; five B．five; five C．five; fifth 【答案】C 【详解】句意：这栋楼有五层。我住在第五层。 考查数词用法。 fifth第五，序数词；five五，基数词。根据“There are...floors in the building.”可知，此处描述总数，需基数词five；根据“on the...floor.”可知，此处表顺序，需序数词fifth。故选C。 14．—How do you read the number 40, 391? —It’s ________. A．four thousand, three hundreds and ninety-one B．forty thousand and three hundred and ninety-one C．forty thousand, three hundred and ninety-one 【答案】C 【详解】句意：——你怎么读数字40, 391？——它读作forty thousand three hundred and ninety-one。 考查数词表达。在英语中，当thousand、hundred等词前有具体数字修饰时，其后不能加s，所以“四十千”应表达为forty thousand；“三百”应表达为three hundred；在表示“几十几”时，十位数和个位数之间要用连字符“-”连接，但当表达几百几十几时，百位和十位之间用and连接，十位和个位之间不用连字符，所以“九十一”应表达为ninety-one，且“三百”和“九十一”之间也要用and连接。综上，40, 391应读作forty thousand three hundred and ninety-one。故选C。 15．—How do you say 803,156,009? —______. A．Eight hundred and three million, one hundred and fifty-six thousand and nine B．Eight hundred and three million, one hundred fifty-six thousand and nine C．Eight hundreds and three millions, one hundred fifty-six thousands and nine D．Eight hundred and three million, one hundred and fifty-six thousand, nine 【答案】A 【详解】句意：——803,156,009这个数字怎么读？ ——八亿零三百一十五万六千零九。 考查基数词的朗读。英语中数字的读法是从右往左每三位划为一个单位，每组内部百位和十位之间用and连接，若十位为0，百位和个位之间也用and，且单位词 (billion、million、thousand和hundred) 前有具体的数字时用单数；803156009可划分为803,156,009，其中“803”对应的单位是“million”，“803”读作“eight hundred and three million”；“156”对应的单位是“thousand”，“156”读作“one hundred and fifty-six thousand”；在“009”中，百位和十位均为“0”，所以应读作“and nine”；所以，“803,156,009”应读作“eight hundred and three million, one hundred and fifty-six thousand and nine”。故选A。 16．I have seen Nezha 2 twice. I plan to see it ______ time during this May Day Holiday. A．a second B．a third C．the third D．three 【答案】B 【详解】句意：我已经看过两次《哪吒 2》了。我计划在今年五一假期再看一次。 考查序数词用法。a second time再一次；a third time再一次，又一次；the third time第三次；three三，基数词。根据上文“I have seen Nezha 2 twice.”可知，说话人已经看了两次《哪吒 2》，所以此处是计划在五一假期再看一次，应用“a third time”强调在原有次数 (两次) 基础上的“额外一次”，不强调顺序。故选B。 17．— Can you read the number “40,424,000” in English? — Yes, ________. A．forty thousand, four hundred and twenty-four million B．forty million, four hundred, twenty four thousand C．forty million, four hundred and twenty-four thousand 【答案】C 【详解】句意：——你能用英语读出数字“40424000”吗？——是的，四千零四十二万四千。 考查数字表达。40424000读作forty million, four hundred and twenty-four thousand。故选C。 18．— Can you say the number 567,120 in English? — Yes. ________. A．Five hundred and sixty-seven one hundred and twenty B．Five hundreds and sixty-seven thousands one hundred and twenty C．Five hundred and sixty-seven thousand one hundred and twenty D．Five hundreds and sixty-seven thousands one hundred and twenty 【答案】C 【详解】句意：——你能用英语说出数字567,120吗？  ——可以。Five hundred and sixty-seven thousand one hundred and twenty. 考查数字表达。million、hundred前有具体数字时不变为复数，排除B和D；百位和十位中间加and，百万和千、千和百中间均不用连词and，故选C。 19．On her ________ birthday, she got an iPad as a gift from her father. A．twelve B．twelfth C．the twelve D．the twelfth 【答案】B 【详解】句意：在她十二岁生日那天，她从父亲那里得到了一台iPad作为礼物。 考查数词。twelve十二，基数词；twelfth第十二，序数词。根据“On her…birthday”可知，此处表示顺序，用序数词；因空格前有物主代词“her”，所以此处不再使用冠词the。故选B。 20．My grandma told me the number “9” stands for “long lasting”. So I chose the ________ floor to live on. A．nine B．eighty C．ninth D．eight 【答案】C 【详解】句意：我奶奶告诉我数字“9”代表着“长长久久”。因此我选择住在九层。 考查数词。nine九；eighty八十；ninth第九；eight八。由单数名词floor及定冠词the可知，此处应用序数词，the ninth floor指“第九层”，故选C。 21．This building has ________ floors. Our classroom is on the ________ floor. A．four; two B．four; second C．fourth; two 【答案】B 【详解】句意：这座大楼有四层。我们的教室在第二层。 考查基数词和序数词辨析。four四，two二；fourth第四，second第二。根据题意可知，第一空表数量，用基数词，four floors；第二空是第二层，用序数词，second floor。故选B。 22．There are ________ months in a year. March is ________ month of the year. A．twelve; third B．twelfth; the third C．the twelve; third D．twelve; the third 【答案】D 【详解】一年有12个月。三月是一年的第三个月。 考查基数词和序数词辨析。根据题意可知，一年有12个月，且months是名词复数，所以应填基数词twelve，基数词前不用the；第二空是第三个月，所以应填序数词third，序数词前要用the。故选D。 23．—Today’s ________ class is music and it is my favorite. —I like music, too. A．one B．the one C．first D．the first 【答案】C 【详解】句意：——今天的第一节课是音乐，这是我最喜欢的。——我也喜欢音乐。 考查序数词。one一个；first第一。根据“class is music”和题干语境可知，是指今天第一节课是音乐。当序数词前有名词所有格修饰时，去掉the。故选C。 24．—What is twenty and forty? —It’s ________. A．fifty B．sixty C．seventy 【答案】B 【详解】句意：——二十加四十是多少？——六十。 考查数字运算。fifty五十；sixty六十；seventy七十。根据“What is twenty and forty”可知二十加四十是六十。故选B。 25．This morning we have ________ classes, and the ________ class is math. A．four; four B．fourth; four C．four; fourth 【答案】C 【详解】句意：今天早上我们有四节课，第四节课是数学。 考查基数词与序数词的用法。four四；fourth第四。根据“we have...classes”可知，第一空表示数量，修饰复数可数名词，因此应用基数词；第二空位于定冠词the之后，用序数词表示顺序。故选C。 26．My grandparents have _________ daughters.
