注意：基数词及序数词重要用法
 1. 基数词的用法
基数词用于表示事物的数量，在表示基数词时，要特别注意hundred, thousand, million, billion等几个词的用法：若其前用了基数词，则不论其面是否有of，都必须用单数形式(此时若带of则通常表示特定范围中的一部分)；若泛指数百、数千、数百万等，则用 hundreds of, thousands of, millions of 等这样的结构。如：
Two hundred of the students are needed to plant trees this morning. 今天中午需要200个学生去植树。
Hundreds of people attended the famous director’s farewell concert. 好几百人出席了这位著名指挥家的告别音乐会。
Thousands upon thousands of English words come from foreign tongues. 成千上万英语单词来自外来语。
2. 基数词的复数用法
逢整“十”的基数词的复数形式可用于表示某人的大约年岁和世纪中的年代。如：
The war broke out in the nineties. 这次战争爆发于90年代。
Karl Mark began to learn the Russian language in his fiftieth. 马克思五十多岁开始学俄语。
3. 序数词的用法
序数词用于表示事物的顺序，一般由与之相应的基数词加th构成(但有特殊形式需特别记忆)；序数词主要用作定语，前面一般要加定冠词(或物主代词)。如：
Their second son is a doctor. 他们的二儿子是个博士。
The hundredth cave that George has discovered in his lifetime is near the Alps. 乔治一生中找到的第一百个山洞在阿尔卑斯山附近。
注：序数词前有时可用不定冠词，表示“每一，又一”。如：
We’ll have to do it a second time. 我们将再做一遍。
词尾加上-th(fourth,sixth)
一、二、三，特殊例，
结尾字母t,d,d(first,second,third) 八去t,九去e,(eighth,ninth)
ve要用 f替;(fifth,twelfth)
ty将y改成i, th前面有个e。
若是碰到几十几， 前用基来后用序。 
或记忆为：一、二、三，特殊记，词尾字母t,d,d  八加h,九减e,逢十改y为ie
 f要把ve替，还有th莫忘记
【语言实践内容梳理】
1. 数词分基数词和序数词。基数词表示数目，序数词表示顺序。
基数词
(1)1～12为独立的单词，有其各自的形式。如one，two，three，…twelve等。
(2)13～19都以teen结尾，单词中的两个音节都读重音。如thirteen，fourteen…nineteen等。
(3)20～90十位数的整数都以-ty结尾，单词中的第一个音节重读。如twenty，thirty…ninety等。
(4)hundred是“百”，thousand是“千”，ten thousand是“万”，one hundred thousand 是“十万”，million是“百万”，ten million 是“千万”。
(5)在表示一个具体的数目时，hundred，thousand，million 后面都不能加“s”。如:two thousand，seven million等。在表示一个不确定的数目时，hundred， thousand，million 后面要加“s”。如：“成千上万”thousands of，“数百万”millions of 等。
(6)20以上的基数词的读法：
a. 两位数的读法，在十位和个位之间加连字符(即“-”)如：22 twenty-two， 35 thirty-five
b. 三位数的读法，在百位之后加“and”。如：136 one hundred and thirty-six， 498 four hundred and ninety-eight
c. 四位及四位以上数的读法，只在百位之后加and，而千位、万位以上的数后面不加任何词，只按顺序读。如：1 234 one thousand two hundred and thirty-four，
5 864 327 five million eight hundred and sixty-four thousand three hundred and twenty-seven
2. 序数词
(1)第一、第二、第三分别为first，second，third。
(2)第四到第十九都由相应的基数词加th构成。如：fourth，seventh等。要注意fifth，eighth，ninth和twelfth的拼写法和读法。
(3)十位数的序数词由相应的基数词去掉词尾y加ieth构成。如：twentieth，fiftieth等。
(4)第二十一到九十九等，前面的十位数用基数词，后面的个位数用序数词，中间用连字符“-”连接。如：twenty-first，twenty-ninth，seventy-eighth 等。
(5)第一百、第一千、第一百万分别在相应的基数词后面加th。即:hundredth，thousandth，millionth。
(6)序数词之前一般要加定冠词或代词。如：
The second truck is carrying fewer baskets than the first one.
This is her first visit to China.
有时，序数词前用不定冠词，表示“再一、又一”的意思。如：
He failed once. Then he tried a second time. 他曾经失败一次，然后他又试了一次。
3. 年月日表达法
(1)年份，每两位数读一个词。如：
1949 nineteen forty-nine 1900 nineteen hundred
(2)先月后日，日子要读成序数词。如：
5月1日 May (the) first可写成 May 1
3月8日 March (the) eighth可写成March 8
(3)先日后月，在月份之前加of。如：
5月1日 the first of May
3月8日 the eighth of March
(4)年月日同时出现，把年代放在最后，年代前用逗号隔开。
如1949年10月1日，可写成：the first of October，1949或October (the)first，1949。
4. 时刻表达法
(1)用基数词，按顺序读。如：
7：30 seven thirty， 8：15 eight fifteen， 12：00 twelve (o’clock)
(2)用介词past，past之前为分钟数(须在半小时以内，包括半小时)，
past之后为钟点数。
如： 6：11 eleven past six ，7：15 fifteen (a quarter) past seven
9：30 thirty (half) past nine
(3)用介词to，to前为分钟数(须在半小时以上,不包括半小时)，to之后为下一个钟点数，
表示“差几分到几点”。如：
6：58 two to seven，7：45 fifteen (a quarter) to eight
5. 编号表达法
(1)用No. No. (读Number)后加数字，数字读基数词。
如：No. 1 Number One， No. 3 bus Number Three bus
(2)用序数词 词序为：the + 序数词+名词 如:
the first lesson，the Second World War
(3)用基数词 词序为：名词(词首字母大写)＋基数词(如用英语拼写，词首字母也要大写)如：Lesson One，Class Four，World War Two。此种方法较常见，特别是当数字较长时。如：
Room 306，No. 106 Middle School。
6. 分数表达法
分子用基数词，分母用序数词，若分子大于1时，分母要在序数词后加s。如：
1/3，one third，2/5，two fifths等。
7. 数学运算的表达法
“加”用plus或and，“减”用minus，“乘”用times，“除”用divided by，动词多用单数。如：
3+5=8 Three plus/and five is eight. 9-2=7 Nine minus two is seven.
6×5=30 Five times six is thirty. 8÷2=4 Eight divided by two is four

31. D【详解】句意：这座塔建于数百年前。
考查数量表达。hundred of为错误选项；two hundreds为错误选项；two hundred of……中的二百；hundreds of上百。根据情境和“years ago”可知，应该使用“hundreds of”，表示“上百年前”。故选D。
32. D【详解】句意：外星人在几千年前来到地球并建造了一些建筑物。
考查thousand的用法。thousand“千”，其前没有具体数字时后+s, 并跟of，即thousands of“几千，成千的”，故选D。

数字运算。two thirds 三分之二；two fifths 五分之二；one third三分之一；one fourth四分之一。根据“There are sixty students in our class.”以及“You have thirty-six girls.”可推知，女孩占班级人数的五分之三，那么男孩就占班级人数的五分之二。故选B。

考查介词辨析。at在；for后接一段时间；by到……为止；in后接某年某月某季节。at age+年龄，表示“具体的年龄”，故第一空填at。in one’s+基数词的复数形式，表示“在某人几十岁时”，故第二空填in，故选C。

44. thousands of tourists come to【详解】根据中英提示可知，空格处表示“成千上万的游客来……”，thousands of“成千上万的”，后面跟复数tourists“游客”，come to do sth.“来做某事”；根据“is”可知，句子陈述一般事实，应用一般现在时，主语为复数“thousands of tourists”，谓语动词用原形come。故填thousands of tourists come to。
45.      thousands     of【详解】根据中英文对比可知，英语部分缺少的是“数以千计的”，可用短语thousands of“数以千计的”，故填thousands；of。
46.      first     place【详解】空处缺少“第一的位置”；“第一”first，常与定冠词the连用；“位置”place，被the first修饰，应用单数形式。故填first；place。
47.      Neither Lily nor her mother is satisfied with the sofa     takes up two thirds【详解】根据汉语可知，本句时态是一般现在时；表示“……和……都不”应用短语neither...nor...连接两个主语，谓语动词遵循“就近原则”；“她妈妈”her mother；“满意……”即“对……满意”be satisfied with；“这个沙发”the sofa。主句的谓语动词由her mother决定，用三单形式；“占用”take up；“三分之二的……”two thirds of；从句主语是it，谓语动词用三单形式。故填Neither Lily nor her mother is satisfied with the sofa；takes up two thirds。
48. one hour and a half##one and a half hours##an hour and a half【详解】固定句型“It takes/took sb+时间+to do sth”表示“做某事花费某人多少时间”，“一个半小时”有三种表达方法one hour and a half/one and a half hours/an hour and a half。故填one hour and a half/one and a half hours/an hour and a half。
49.      to make clothes for me by     her forties【详解】表达“过去常常做某事”用used to do sth.，“为我手工制作衣服”make clothes for me by hand，故第一个空填to make clothes for me by；表达“在某人四十多岁的时候”用in one’s forties，forties表示的是时间段，即年龄上的四十岁到四十九岁之间，故第二个空填her forties。故填to make clothes for me by；her forties。
50.      thousands      of【详解】由汉语和英语翻译可知，“成千上万”译成：thousands of；注意：与of连用thousand需用复数。故填thousands；of。
51. took up three fourths of##took up three quarters of【详解】根据中英文对比可知，take up“占据”；“四分之三”英文表达是“three fourths”或“three quarters”；由于本句中but后面的分句使用的时态是一般过去时，因此前面也应该是一般过去时；of“……的”。故填took up three fourths of/took up three quarters of。
52. millions of【详解】根据汉语句意，可知空格要填入表示“数百万本”的表达，“数百万”可用millions of来表示，后接可数名词的复数形式。故填millions of。
53. a regular job until he was in his thirties【详解】“一份固定的工作”a regular job；“直到……才”not...until...，until引导时间状语从句，主语是一般过去时，从句也应用一般过去时；in one’s thirties“在某人的三十岁”，主语是he，所以用his代替one’s，be动词用was。故填a regular job until he was in his thirties。
54.      Millions     of     were     sent【详解】通过中英文句子对照可知，英文句子中需要翻译的部分是“数百万的”和“送到”，“数百万的”英文表达是millions of，因其位于句首，首字母要大写；“送到”英文表达是send，动词；主语“rescue things”和谓语动词“send”之间是被动关系，因此用被动语态，再由时间状语“three days ago”可知用一般过去时的被动语态，即was/were+动词的过去分词，主语是复数，用were，send的过去分词是sent；故填Millions；of；were；sent。
55.      hundreds     of     were     sent【详解】hundreds of“数百个”，send“派出”，根据“by the government”可知，此处用被动语态，且根据“Last week”可知，句子用一般过去时被动语态was/were done，主语是复数形式，助动词用were，故填hundreds；of；were；sent。
56.      Millions     of【详解】本题考查数词的使用，“数以百万计”应用“millions of”表示，句首单词首字母大写。故填Millions；of。
57. it necessary to finish three quarters##it necessary to finish three fourths【详解】根据中英文可知，本句用“sb. thinks it+形容词+to do sth.”的结构，这里it是形式宾语；有必要：necessary；完成：finish，本结构用动词不定式作真正的宾语，所以这里用to finish；四分之三：three quarters或three fourths。故填it necessary to finish three quarters/it necessary to finish three fourths。
58.      hundreds     of【详解】此处表示概数，应用短语hundreds of“数百”，故填hundreds of。
59.      hundreds     of【详解】固定搭配：hundreds of表示“数以百计的”，故填hundreds；of。
60. the third【详解】third第三，在序数词前加定冠词the，故填the third。
61.      quarter     to【详解】表达时间时，分钟数超过30，用“所差分钟数+to+下一整数点”表示，quarter表示“一刻钟”，故填quarter，to。
62.      thousands     of【详解】根据中英文对照可知，thousands of“成千上万的”。故填thousands；of。
63.      thousands     of【详解】此处缺的是“成千上万的”，表达为thousands of，是概数的表达，故填thousands；of。
64.      Hundreds     of【详解】根据中英文对比可知，空格处应填入意为“几百……”的短语。hundreds of为固定搭配，意为“数百、成百上千的”，用于修饰名词，且位于句首hundreds首字母应大写。故填Hundreds；of。
65. spent twenty minutes【详解】花费时间做某事spend time doing sth.；20分钟twenty minutes。陈述过去事实，用一般过去时，spend的过去式是spent。故填spent twenty minutes。
66. four hundred and ninety【详解】结合中文句意提示，可知缺少的是“四百九十”，hundred百，与基数词搭配表示具体的数字时hundred不加s；ninety九十。故填four hundred and ninety。
67.      Hundreds     of【详解】hundreds of“数百……”，后加名词复数；hundreds of people“数百人”，注意首字母大写。故填Hundreds of。
68. have been interested in dancing since I was three.【详解】句意：——你为什么这么擅长跳舞？——我自从三岁起就对跳舞感兴趣了。“对……感兴趣”用be interested in，动词短语；be interested in+doing…，对做……感兴趣；跳舞，dance，动词；我三岁时，I was three。当since引导的时间状语从句为一般过去时态时，主句应该用现在完成时态。现在完成时态构成：have/has+过去分词。主语是I，所以应该用have，故填have been interested in dancing since I was three.
69. on January 12, 2020【详解】“2020年1月12日”为具体的一天，其前应加介词on；January 12, 2020“2020年1月12日”。故填on January 12, 2020。
70. 5 meters long【详解】根据中文可知英文句子缺少部分为“长5米”。在英文中表示“事物的长、宽、高等”时，其表达方式为：基数词 + 表示“度量”的名词（meter，foot等）+ 形容词（long，wide，tall等）。所以 “长5米”的英文表达为：5 meters long。注意因为5表示复数，所以meter后要加s，故填5 meters long。
71.      twentieths     regarded/regard【详解】根据题干中汉英对比可知要翻译“二十”和“视……为……”。分数中分子在前，用基数词，分母在后，用序数词，分子seven大于1，分母要用复数形式；“二十”译为序数词twentieth，其复数是twentieths。视……为…… regard ... as ...，题干中无明显信息说明时态，结合事实可知可用一般过去时或一般现在时，主语是“Seven twentieths of the students”，谓语用过去式regarded或动词原形regard。故填twentieths；regarded/regard。
72.      one      fifth
【详解】根据语意可知，本题考查分数的表达。分数表达适合“子基母序”的原则，即分子为基数词，分母为序数词，当分子大于一时，分母用其复数形式，故“五分之一”应表示为one fifth。故填one；fifth。
73.      four     more     magazines【详解】基数词+more还需要……，再几个，故此处应为four more；magazine杂志，可数名词，此处用其复数形式。故填four，more，magazines。
74.      hundreds     of【详解】根据中英文对比可知，句子缺少“成百上千”，表达约数含义，其英文表达为“hundreds of”，修饰“medical workers”。故填hundreds；of。
75.      Hundreds     of【详解】根据中英文对比可知，空格处应填入意为“数百人”的短语。hundreds of为固定搭配，意为“数百”，符合句意，且位于句首，hundreds首字母应大写，故答案为(1). Hundreds (2). of。
76. hundreds of【详解】根据翻译可知英语句子缺少“数百棵”含义，用hundreds of，后面直接跟名词。故答案为hundreds of。
77.      Walk along/down     at the second crossing【详解】根据中英文对照可知，这里缺的是“沿着”和“在第二个十字路口”，英语中表达“沿着……”是walk along/ down，这里是祈使句，以动词原形开头，所以直接填原形；而表达“在第几个路口”要用介词at，“第二”是second，序数词前面要加定冠词the，“十字路口”是crossing，所以这里应该填at the second crossing，故答案为Walk along/down，at the second crossing。
78.      Hundreds     of【详解】根据原句，可知此处缺少“成百上千”的表述，可知是hundreds of，意为“数百，成百上千”，故答案为Hundreds of。

88. 句意：从下个秋季学期开始，中小学生将每周至少上一节课，来学习做饭和打扫卫生之类的基本家务劳动技能。根据句中的“basic household skills like cooking”以及首字母提示可知此处是指做饭和打扫，应填动名词cleaning，和前面的cooking作为介词like的并列宾语。故填(c)leaning。
