数词专项练习(附答案解析)
数词专项练习(附答案解析)一、选择题。
1.Nowadays ______of business letters are written in English.A. two thirdB. two thirdsC. two threeD. second three本题考查的知识点是分数的表达。
句意:现如今,有三分之二的商务信函都是用英语写的。
分子用基数词,而且是2,大于1,所以分母用复数,而且用序数词,因此选B.分数表达法为:分子用基数词,分母用序数词;分子在前,分母在后;若分子大于1时,分母用复数。
2.---Good news! Bill won _____ medal in the long jump just now. ---Really? That’s his ____ one at our sports meeting.A. a; fourB. an; fourthC. a; fourth本题考查的知识点是不定冠词以及序数词的用法。
句意:好消息!比尔在刚才的跳远比赛中赢得了一枚奖牌。
——真的吗?那是他在我们的运动会上赢得的第四枚了。
因为Bill赢了一枚奖牌,是泛指,用不定冠词,而且medal的第一个音节是辅音,所以用a, 而后面指第四枚,应该用序数词,因此答案为C。
名词第一次出现时用a或an, 表泛指。
“第四枚”应该用序数词fourth.3.---Peter, how old is your father this year?---_____. And we just had a party for his_____ birthday last week.A. Fortieth; fortyB. Forty; fortyC. Forty; fortiethD. Fortieth; fortieth本题考查的知识点是基数词与序数词的综合运用。
句意:——彼得,你父亲今年多大?——40岁。
上周末我们刚为他举行了40岁的生日聚会。

数词的用法以与练习题
数词数词分基数词和序数词。
基数词表示数目,序数词表示顺序。
一、基数词的构成1.1—12的基数词是独立的单词,即:2.13—19的基数词以-teen结尾。
如:但13,15,18较特殊,13—15—18—。
3.20—90的整十位均以-ty结尾。
如:sixty,seventy,但20,30,40,50,80,90较特殊,20—30—40—50—80—90—。
4.十位数与个位数之间要加连字符号“-”,如:28—twenty-eight,96—ninety-six。
5.百位和十位(若无十位则和个位)之间加and,如:148—one hundred and forty-eight 406—four hundred and six。
6.hundred(百),(千),(百万),(十亿)等前面即使有具体的数词,也不能在它们的后面加s。
如:600—six hundred,8百万—-7.2,510=two thousand five hundred and ten;84,296=eight-four thousand two hundred and ninety-six;8.hundred,thousand,million用复数形式修饰名词时要用“of+复数名词”,如:数以百计的年轻人hundreds of young people;数以千计的书thousands of books。
注意:hundreds of /thousands of/millions of +复数名词,其前面不能加具体的数词,但可加several或many。
遵循两无原则9.基数词+单数名词+形容词构成合成形容词。
如:一个五岁的男孩a five-year-old boy;一座800米长的桥;10.句型:主语+is +about(大约)/over =more than(超过)/nearly(接近)+具体数词+meter(s)/kilometer(s)/kilo(s)long /high /tall /deep /away等。

1.Nowadays ______of business letters are written in English.A. two thirdB. two thirdsC. two threeD. second three本题考查的知识点是分数的表达。
句意:现如今,有三分之二的商务信函都是用英语写的。
分子用基数词,而且是2,大于1,所以分母用复数,而且用序数词,因此选B.分数表达法为:分子用基数词,分母用序数词;分子在前,分母在后;若分子大于1时,分母用复数。
2.---Good news! Bill won _____ medal in the long jump just now.---Really? That’s his ____ one at our sports meeting.A. a; fourB. an; fourthC. a; fourth本题考查的知识点是不定冠词以及序数词的用法。
句意:好消息!比尔在刚才的跳远比赛中赢得了一枚奖牌。
——真的吗?那是他在我们的运动会上赢得的第四枚了。
因为Bill赢了一枚奖牌,是泛指,用不定冠词,而且medal的第一个音节是辅音,所以用a, 而后面指第四枚,应该用序数词,因此答案为C。
名词第一次出现时用a或an, 表泛指。
“第四枚”应该用序数词fourth.3.---Peter, how old is your father this year?---_____. And we just had a party for his_____ birthday last week.A. Fortieth; fortyB. Forty; fortyC. Forty; fortiethD. Fortieth; fortieth本题考查的知识点是基数词与序数词的综合运用。

【点评】考查短语辨析及分数表达,注意平时识记,理解句意。
【答案】A
【解析】【分析】句意:——你知道那个坐在彼得旁边的男孩吗?——是的。他是彼得的朋友。他们正在庆祝他的九岁生日。分析句子结构可知,第一空所在句子是定语从句,先行词是人,连接词在从句中作主语,所以应该用who/that引导,which连接定语从句时先行词应该是物,故排除C;nine九,基数词;ninth第九,序数词;第二空根据空后的birthday为名词单数可知,此处需要序数词,表示某人几岁生日应该用序数词表示第几个生日,故选A。
小学英语数词及专项训练
小学英语数词与专项训练一、数词的分类:基数词和序数词。
基数用于表示数量多少,而基数词用于表示次序,常在日期中出现。
区别:基数词前面没有“the〞;序数词前一定要有“the〞。
1、超过二十以上的两位数需要在个位和十位之间加上“-〞。
如:21 twenty-one2、用基数词来修饰可数名词时,一定别忘了它的复数形式。
如:十八个男孩 eighteen boys3、用基数词修饰不可数名词时,如是复数,变它的量词为复数。
如:两碗米饭 two bowls of rice4、序数词一般加“th〞,特殊的有:first, second, third, fifth, eighth, ninth, twelfth;二十与二十以外的整十:twentieth, thirtieth, fortieth…“第几十几〞:前面整十不变,后面“几〞改为序数词。
如:88 eighty-eighth巧记基数词和序数词:1,2,3,特殊记,加th从4起;8少t,9去e,逢5逢12ve变f;20~90,y要变ie;若是几十几,前基后序别倒位.二、数词的表示方法:三、数词的用法1. 章节、页数的读法第一章:the first chapter ; Chapter One第二节:the second section ; Section Two第三课:the third lesson ; Lesson Three第463页:page four six three第2564页:page two five six four或twenty-five sixty-four注意:如果页码的数字较长,通常用基数词。
2. 房间、门牌、的读法第305房间:Room three o〔零〕five长安街76号:seventy-six Chang'an Street:204-2244:telephone number two o〔零〕four two two〔double two〕four four 十一路公共汽车:Bus〔No.〕eleven3. 年代、日期、时刻的读法〔1〕年份是四位数字时,各分成二位来读,eg. 公元1995年:1995〔=nineteen ninety-five〕〔2〕日期使用一般的序数词来读取eg. 5月10日:May 10th〔=May tenth〕〔3〕时刻通常用基数词来读eg. 8点45分:8: 45〔=eight forty-five〕〔4〕年代表示法:eg. 二十世纪九十年代:1990's nineteen nineties4. hundred, thousand, million用法:hundred, thousand, million前面有具体数字,要用单数形式,但如果它们后面有of,那它们要用复数形式,同时,前面不能再加具体的数目。
数词的正确用法与练习解析
数词的正确用法与练习解析以下是一些数词练习题及其答案和详解:练习题一:1.There are ___students in our class. (A) one hundred and forty-two (B)one hundred forty-two (C) one hundred and forty two答案:A详解:在英文中,当表达一百以上的数字时,需要在“hundred”前后加上“and”。

序数词一般在基数词后加“-th”,而“twelve”的序数词形式是“twelfth”。
因此,正确答案为“twelfth”。
练习题三:3.How many ___of apples do you want? (A) kilogram (B) kilograms (C)kilo答案:B详解:在英文中,当表示数量时,如果数字大于1,后面的名词需要使用复数形式。
同时,“kilogram”是可数名词,所以需要使用复数形式“kilograms”。
因此,正确答案为“kilograms”。
练习题四:4.Half of the students in our class are girls. That means ___of thestudents are boys. (A) half (B) the other half (C) another half答案:B详解:在英文中,“half”表示“一半”,如果要表示“另一半”,需要使用“the other half”。
