C. two three

D. second three

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; four

B. an; fourth

C. 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; forty

B. Forty; forty

C. Forty; fortieth

D. 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。第一个空回答年龄用基数词;第二个空表示第40个生日,用序数词,因此选C.

基数词表示数目和顺序,序数词表示数目的顺序。

4. The road is over ______ meters long.

A. six hundred and fifty-two

B. six hundreds and fifty-two

C. six hundred, fifty-two

D. six hundred, fifty and two

本题考查的知识点是长度的表达。

句意:这条公路超过652米长。652是三位数,应该先读百位数,再加and,最后读52,因此选A.

在读三位数或者三位数以上的基数词,,需在十位数之前(如十位

数是“0”,在各位前)加连词and.

5.---How much does it cost to build the school library?

---Four _____ yuan.

A. million

B. millions C .millions of D. million of

本题考查的知识点是数词作为定语的用法。

句意:——修建学校图书馆需要多少钱?——四百万元。在million (百万)前如果有具体数字,则要用单数形式,且后面不能与of连用,因此选A。

hundred, thousand, million, dozen, score这些词前面如有表示具体数字的词,它们不能加-s,若与of连用则需加of。

6. I got a beautiful bike on ________ birthday. I like it very much.

A. fifteenth

B. fifteen

C. my fifteen

D. my fifteenth

本题考查的知识点是形容词性物主代词与序数词作定语的用法。

句意:在我15岁生日时,我得到了一辆漂亮的自行车。我非常喜欢它。我的15岁生日,也就是第15次生日,应该用序数词,所以选D。

7. She went to the countryside _____________.

A. in the morning at 9/on June first,1968

B. on June first, 1968/ in the morning at 9

C. at 9 in the morning/ on June first,1968

D. on June first, 1986/ at 9 in the morning

本题考查的知识点是时间的写法。

句意:在1968年六月一日的早上九点她去了乡下。时间的写法是从最小的开始,依次从左至右写过来。

如果在早上/中午/晚上与日期之间有of连接,则需要把早上/中午/晚上前的in 改为on,如on the morning of May 1st,2012

8. Could you tell us how to read the number 18,306,211?

A. eighteen million, three hundred and six thousands, two hundred eleven

B. eighteen million, three hundred and six thousand, two hundred and eleven

C. eighteen millions, three hundred and six thousands, two hundreds and eleven

D. eighteen thousand, three hundred and six , two hundred eleven

本题考查的知识点是较长数字的读法。

句意:你能告诉我怎么读18,306,211这个数吗?读数时,数字不需要加上s, 故排除A和C, 而百位和十位之间需要用and连接,故选B.

读数字时要先从右边开始确定出数位,右边开始数第三位要读thousand,再往前读三位读million,接着往前再数三位就是billion;数词单位hundred, thousand, million和billion之间读时要加and;如果十位是0,也读and。

9. Bill said they were going to have ________ holiday.

A. a two-weeks’

B. a two-week

C. two weeks’

D. two weeks

本题考查的知识点是形容词数词与名词连接作定语。

句意:Bill说他们打算度假两个星期。holiday是可数名词,所以前面不能丢了冠词;形容词放在a holiday的中间,two和week作形容词,应该在中间加上连字符,故选B.

由数词、连字符和名词组合可组合成形容词,但词不能加-s。

10. ---How many teachers are there in your school?

---__________, but I am not sure.

A. Hundreds

B. Hundred

C. Hundreds of

D. One hundred

本题考查的知识点是数词在肯定语气中的运用。

句意:——你们学校有多少?——一百名,但是我也不确定。

由题干问句中“How many”可知设空处应表示一个具体数目,故选

D.

hundred, thousand, million和billion后面加s,再加of,表示成百上千等不确定的数目。

11. ---What can I do for you?

---I’d like to take _________ these potatoes.

A. two dozen of

B. two dozen

C. two dozens

D. two dozens of

本题考查的知识点是数词与量词的搭配使用。

句意:——想买些什么?——我想买两打西红柿。因为前面有数字two,所以dozen不需要加s, 而后面有限定词these,所以要加of,故选A。

dozen, score前面有基数词时,不能用复数形式,后面通常不能接of,但如果后面有the, these,those等限定词,还需加of.

12. ---How long will you stay there?

---For ________.

A. one and two days

B. one and two day

C. one or two day

D. a day or two

本题考查的知识点是二者选一与数词的综合运用。

句意:——你会在那儿呆多久?——两天吧。如果two后面紧接着day,则需要在day上面加s,因此排除C和D。

A的意义不明,故选D. a day or two是习惯用法,意为“一两天”。

13. _______ the students usually surf on the Internet and get information.

A. 60 percents of

B. 60 percent

C. 60 percent of

D. 60 percents

本题考查的知识点是百分数的表达。

句意:百分之六十的学生都喜欢上网和搜资料。因为后面有the students,所以要加上of, 而且表示percent后面不需要加s,故选C。

百分数的表示法:“基数词+percent of”。Percent后不加s。

14. Which is right?

A. 2009, June 25

B. 25th June,2009

C. June 25, 2009

D. June 25st,2009

本题考查的知识点是年月日的表达法。

A和B的顺序不对,而且25的序数词是twenty-fifth, D的表达不对,故选C.

日期的表达法:“月份+日期,年代”,日期写序数词或基数词都可,一般都习惯写基数词,但读时要读成基数词。

15. It took me ____ to find out the key to the drawer.

A. one and half hours

B. one and a half hours

C. one and a half hour

D. one and half hour

本题考查的知识点是时间段的表达。

答案:eight-fifth two hundred and forty-third

三、将下列句子补充完整。

1.他每两天跑步一次。(用third表示)

初中英语数词专项练习

数词 数词分为基数词和序数词两种。表示数目或数量多少的词叫基数词;表示数目顺序的词叫序数词。 一. 基数词 1. 基数词就注意以下几点: (1)几十几的基数词的十位数与个位数之间要用连字符“-”连接。如: eighty-five 85 twenty-six 26 (2)三位数的基数词须在百位和十位(若无十位则和个位)之间用and连接。如: three hundred and sixty-five 365 two hundred and six 206 (3)基数词的复数形式。当基数词hundred, thousand, million, billion等词前有具体数词或several修饰时,必须用单数。如: several hundred year’s ago几百年前 two thousand students两千个学生 2. 基数词的特殊用法: (1)表示“几十年代”或“几十岁”时,用逢十的基数词的复数形式。如: in the 1990’s 20世纪90年代 in o ne’s twenties在某人20多岁时 (2)用在习语中。如: in twos and threes三三两两地 二. 序数词 序数词应注意的几点事项: 1. 多位数的基数词变成序数词时,只需将末位基数词变成序数词,前边的基数词不变。如: forty-two 42 forty-second第42 nine-hundred 900 nine-hundredth第900 2. 当序数词用阿拉伯数字表示时,必须在数字后加上序数词的最后两个字母。如: 21st第21 32nd第32 3. 序数词前一般要用定冠词the,如果序数词前用a或an时,则表示“又一;再一”(没有具体范围的限制)。如: Though he had failed twice, he wanted to try a third time. 尽管他已失败了两次,他还想再试一次。 The little monkey had had three apples, and he wanted to eat a fourth one. 那只小猴子已经吃了3个苹果,他还想再吃一个。 三. 分数和百分数 1. 分数 (1)分数的分子用基数词,分母用序数词。如: one fifth五分之一 one tenth十分之一 (2)当分子大于1时,分母用序数词的复数。如: two thirds三分之二 five eighths八分之五 (3)当分子是1时,可以用one也可以用a。如: a second = one second a third = one third (4)当分母是2和4时,分别可以用half和quarter代替。如:

小学英语名词数词专项练习题

名词语法和练习题 1. 定义 名词可以分为专有名词和普通名词,专有名词是某个(些)人,地方,机构等专有的名称,如Beijing,China等。普通名词是一类人或东西或是一个抽象概念的名词,如:book,sadness等。普通名词又可分为下面四类:1)个体名词:表示某类人或东西中的个体,如:gun。 2)集体名词:表示若干个个体组成的集合体,如:family。 3)物质名词:表示无法分为个体的实物,如:air。 4)抽象名词:表示动作、状态、品质、感情等抽象概念,如:work。 个体名词和集体名词可以用数目来计算,称为可数名词,物质名词和抽象名词一般无法用数目计算,称为不可数名词。 2. 名词复数的规则变化(情况,构成方法,读音,例词) a. 一般情况在名词后加-s 清辅音后读/s/ map-maps 浊辅音和元音后读/z/ bag-bags /car-cars b. 以s, sh, ch, x等结尾的名词加-es

读/iz/ bus-buses/ watch-watches/brush-brushes/box-boxes c. 以ce, se, ze,等结尾加-s 读/iz/ license-licenses d. 以辅音字母+y结尾的名词把变y 为i再加es 读/z/ baby---babies e. 以o 结尾的名词,变复数时: 1). 加s,如:photo---photos piano---pianos radio---radios zoo---zoos; 2). 加es,如:potato--potatoes tomato--tomatoes 3). 上述a和b两种方法均可,如zero---zeros / zeroes。 f. 以f或fe 结尾的名词变复数时: 1). 加s,如:belief---beliefs roof---roofs safe---safes gulf---gulfs 2). 去f, fe 加ves,如:half---halves knife---knives leaf---leaves wolf---wolves

中考英语数词专项练习题及答案详解

人教版中考英语九年级英语数词专项练习题及答案详解 一、初中英语数词 1.There were about six___________ students in the school building during the earthquake. A. hundred B. hundreds C. hundreds of D. hundred of 【答案】 A 【解析】【分析】句意:地震期间,校舍里大约有六百名学生。hundred,百,基数词,表示具体的数量,其前要用基数词;hundreds of +可数名词复数,表示不确定的数量,固定短语。空格前有基数词six,要用hundred,故答案选A。 【点评】考查基数词hundred的用法。注意hundreds不能单独使用,必须与of放在一起使用。 2.The number of the students in our school is about four __________. _______ of them are girls. A. thousand; Two thirds B. thousands; Two third C. thousands; Two thirds D. thousand; Two third 【答案】 A 【解析】【分析】句意:我们学校的学生人数大约是四人。三分之二是女孩。four基数词后用thousand的原形,分数表达形式是分子是基数词,分母是序数词,分子大于一,分母用复数形式,故三分之二是two thirds,故选A。 【点评】考查数词,注意分数的用法。 3.Two students to the opening ceremony last Friday. A. hundreds; were invited B. hundred; were invited C. hundreds of; invited 【答案】 B 【解析】【分析】句意:上周五有200名学生被邀请参加开幕式。根据题干中的two与选项中的hundred可知此题考查确切数量的表达方式,hundred要用单数形式;students与invite存在动宾关系,此处要用被动语态,由last Friday,可知要用一般过去时,故选B。【点评】考查数量的表达方式以及被动语态。注意确切数量与不确切数量在表达上的不同。 4.We gave away ________ books to the school library last year. A. six thousands B. six thousand C. six thousands of D. six thousand of 【答案】 B 【解析】【分析】句意:去年我们向学校图书馆赠送了六千本书。数词后thousand用单数,thousands of,固定搭配,几千个,不与数字搭配;因此是six thousand或者thousands of,只有B对,故选B。 【点评】考查数词,注意识记thousand的用法。 5.Every year, ________ books are given away to the poor children in the countryside.

2018-2019年广东小升初英语真题及答案解析

2018-2019年广东小升初英语真题及答案解析 班级:___________ 姓名:___________ 分数:___________ 一、选择题 1.当别人对你说Let’s go shopping,你想去应该说: A. Yes,I am. B. OK. 【答案】B 【解析】略 2.When is World Environment Day? It’s ___________.

A.some B.any C.many D.an 【答案】B 【解析】 思路分析:本题考查的是There be 句型否定句。 名师解析:there be句型中的主语是milk,为不可数名词,there be中的be动词用is。There be的否定式直接在is后加not缩写为:there isn’t。表示没有。瓶子里面没有牛奶了。此处需要填一个修饰牛奶的形容词。根据排除法,many,an都是用来修饰可数名词

的。肯定句中用some修饰不可数名词,否定句或疑问句中用any修饰不可数名词。因此,答案为:B。 易错提示:否定句中some变any修饰名词。 6.—Where was my purse? —_______ A.Yes, it was.B.No, it wasn’t. C.On your bed.D.They are in your pocket 【答案】C 【解析】 思路分析:本题考查的是特殊疑问句及其回答。 名师解析:问句以where开头,应该回答地点,不能直接用Yes或No来回答,选项A、B错误,问句的主语my purse(我的钱包)是单数,选项D错误,故答案为:C。 易错提示:注意问句及其答语的时态、人称保持一致。 7.( ) —__________ are you from? —Beijing. A. Do B. What C. Where 【答案】C 【解析】问地点应使用疑问词where(哪里)。 8.( ) Matt likes geography very much. He thinks it ________. A. interesting B. difficult C. boring 【答案】A 【解析】主要考察学生对句意的理解,故选A 9.()_________ can we get there? A. Where B. What C. How 【答案】C 【解析】 10. ______it often ______in winter?
