Could you show me _________ one? A．other B．the other C．another D．others 参考答案： 1．B 【详解】句意：第一中学的九百多名学生将于七月离校。 考查hundred的用法。表示具体的数量：基数词+hundred的单数形式；表示概数：hundreds of。结合选项可知，此处表示具体数量“九百”。故选B。 2．B 【详解】句意：这个城市有800万人。 考查数词。million“一百万”，表确切数目时不能加s，后接复数名词；表示不确切的数目时，要用复数形式，且与of连用。故选B。 3．B 【详解】句意：今年是我们祖国的七十一岁生日。 考查数词辨析。seventy-one七十一，基数词；seventy-first地七十一；the seventy七十，基数词；the seventies七十，基数词复数。根据“birthday”可知，此处应用序数词，表示第七十个生日。故选B。 4．A 【详解】句意：格林夫人住在一个有五层的老公寓里，她将要庆祝她的五十岁生日。 考查数词的用法。在表示有多少楼时，应使用基数词，因此选项B和D不正确；第二空指第五十岁生日，应使用序数词，her后不跟冠词the，排除选项C。故选A。 5．D 【详解】句意：那所学校有500名学生。 考查大数的表达。hundred“百”，当其前有基数词限定时，hundred不加s，也不与of连用；当表示概数时，hundred后要加s，且与of连用。结合选项可知，D选项为正确表达方式。故选D。 6．A 【详解】句意：他们有一个11岁的儿子。 考查复合形容词及不定冠词。根据“son”可知，此处应用复合形容词“基数词-year-old”的结构，即11-year-old，作定语，且此处表示泛指一个11岁的儿子，需用不定冠词，11是以元音音素开头的单词，不定冠词用an。故选A。 7．B 【详解】句意：那辆新车是我父母的。这是他们的第一辆车。 考查名词所有格和序数词。主语That new car是单数形式，可知是两人共同拥有的一辆车， 所以在最后一个名词后加“-’s”即可， 排除选项C、D；序数词前已经有形容词性物主代词their，不再加定冠词the，排除选项A。故选B。 8．D 【详解】句意：国庆节期间，广场上有数百万人。 考查数词表达。millions of意为“数百万”；million表示“百万”，前面有具体数字的时候，不能变复数，故选D。 9．A 【详解】句意：人们在20世纪90年代建造了很多高楼。 考查年代表达。根据“People built many tall buildings”可知，此处表达为许多高楼建立于20世纪90年代。固定短语“in the+年代+s”，意为：某个世纪某个年代。故选A。 10．C 【详解】句意：——看右边！一本书昨天是500美元。今天多少钱？——350美元。 考查数字运算。根据图片中“All Books Today 30% OFF”可知，今天所有图书打七折，所以一本书的价格为：500×70%=350美元。故选C。 11．B 【详解】句意：贵州的夏季十分凉爽，因此成千上万的人来这里度假。 考查大数的表达。thousand意为“千”，前有具体数字时，其后不加s，也不加of；可构成thousands of表示“成千上万的，数以千计的”，修饰可数名词的复数形式，其前不加具体数字。故选B。 12．A 【详解】句意：我有一个9岁的妹妹，她坐校车上学。 考查年龄的表达和介词辨析。9-year-old九岁的；9 years old九岁；by通过；on在……上面。“基数词-year-old”，中间用连字符连接，表示“多少岁的”，是复合形容词，用于修饰名词。“by+交通工具”和“on+冠词/物主代词+交通工具”表示“乘坐某种交通工具”。第一空后的sister是名词，所以第一空应填9-year-old；第二空后的school bus是交通工具，其前没有任何冠词或物主代词，所以第二空填by。故选A。 13．D 【详解】句意：一些科学家说，制造看起来像人的机器人可能需要两年多的时间。 考查数词。hundred数词，“百”，若与数字连用，其后不加s，排除B与C；若不与数字连用，则要加s，即hundreds of “数百的”；more than“超过”，后跟具体数字，排除A。故选D。 14．D 【详解】句意：我昨天花费了一个半小时做我的家庭作业。 考查时间表达法。“一个半小时”的英文表达为an/one hour and a half或one and a half hours。故选D。 15．C 【详解】句意：这个故事发生在两千年前。 考查数词的表达。thousand“千”，前面有具体数字时不能变复数，thousands of…表示“成千上万”，这里表示约数；根据“...two thousand years ago.”可知此处表示两千年之前。故选C。 16．A 【详解】句意：到那花费我大约一个半小时。 考查数量“半”的表达。表达“一个半小时”有两种说法：one and a half hours和one hour and a half。故选A。 17．B 【详解】句意：从上海乘船到曼谷大约需要三天半的时间。 考查时间段的表达。表示“三天半”可用结构three and a half days或者three days and a half。故选B。 18．C 【详解】句意：在这个大城市有800万人。 考查大数的表达。million前有数字eight修饰，此时million只能用单数形式，且后不能加of。故选C。 19．D 【详解】句意：我通常每天花一个半小时做家庭作业。 考查时间表示法。“一个半小时”的表达为：one and a half hours 或者one hour and a half。故选D。 20．A 【详解】句意：我表妹露西将第二次来香港。 考查序数词。second第二；two二；twice两次；twins双胞胎。根据“for the...time.”可知此处表示次数，应用序数词second，故选A。 21．B 【详解】句意：母亲节在五月的第二个星期天。 考查序数词和常识。first第一；second第二；third第三；last最后的。根据常识可知，母亲节在五月的第二个星期天，故选B。 22．B 【详解】句意：——17加23等于多少？——很简单。等于40。 考查数字运算。sixteen16；seventeen17；eighteen18；nineteen19。根据“It’s forty”，可知是问17加23等于多少，故选B。 23．C 【详解】句意：根据以下信息，19名学生喜欢球类运动。 考查数字计算。根据表格中“Soccer 9”和“Tennis 10”可知，喜欢球类运动的是19人，故选C。 24．A 【详解】句意：——这是我的第三个篮球。 ——哇，我觉得你很喜欢打篮球。 考查数词辨析。third第三，前面可用定冠词、名词所有格或形容词性物主代词修饰；the third第三；three基数词，三；the three这三个。根据“This is my … basketball”可知，序数词前已有形容词性物主代词修饰，就不用需要再用the修饰，意为“我的第三个球”。故选A。 25．C 【详解】句意：在我们学校有数百名学生。 考查数词。three hundreds错误写法；three hundreds of错误写法；hundreds of数百；hundred of错误写法。根据选项可知此题考查数词hundred的用法，此题空前没有具体数字，故用hundreds of。故选C。 26．A 【详解】句意：在我们市博物馆里，展出了许多两千年前的旧物。 考查thousand的用法。thousand“千”，表示概数时，前面没有具体的数字修饰，要用thousands of“成千上万的”结构，如果前面有具体的数字修饰，thousand要用单数形式，其后不能加of；根据“there are many old things from two…years ago on show”可知，空前有two修饰，此处应填thousand。故选A。 27．D 【详解】句意：Linda现在12岁了。她经常周末和她三岁的弟弟一起玩。 考查年龄段的用法。根据“Linda is … now”可知，第一空应用“基数词 + years old”表示“某人几岁”的确切年龄，在句中作表语；又根据“with her … brother”可知，第二处应用复合形容词“基数词-year-old”，表示“几岁的”，在句中作定语，修饰brother。故选D。 28．D 【详解】句意：——现在是十点五十分吗？  ——是的，差十分钟十一点。
