篇1：中考英语的数词语法讲解
中考英语的数词语法讲解
（一）数词概述
英语的数词可以分为基数词和序数词两大类。基数词表示数目的多少，如：three，thirty，forty-nine等。而序数词表示的则是这些数目的顺序,如：third，thirtieth，forty-ninth等。数词与不定代词很相似，其用法相当于名词与形容词。中考对数词的考查主要是数词的“复数形式”的应用、分数的构成形式以及词形变化中的基数词转换为序数词。当表示确切的数目时，hundred，thousand，million等数词用单数形式；表达不具体的数目，如成百上千，成千上万等时，hundred，thousand等数词用复数形式，且在其后加介词of。英语中的分数是由“基数词+序数词”构成的。分子用基数词表示，分母用序数词表示，分子大于“1”时，作为分母的序数词要用复数形式。基数词转换为序数词常在词形转换中考查，要特别记住某些序数词的一些特殊变化形式。如：one——first, two——second, three——third, five——fifth, eight——eighth, nine——ninth, twelve——twelfth, twenty——twentieth等等。
（二）基础知识梳理
1．基数词
1）基数词表示数量。13~19的基数词都以-teen结尾，如：thirteen，nineteen等。20~90十位数的整数都以-ty结尾，如：twenty，ninety等。
2）表示两位数词时，十位与个位之间要加连字符。三位以上的'数词，在百位数与后两位数之间，要用and连接。如：four hundred and ninety-seven。注意，千位数与百位数之间用逗号分开，如：five thousand，three hundred and twenty。
3）在表示一个具体的数目时，hundred，thousand，million都要用单数形式。如：several hundred，two thousand，ten million等。在表示大概数目时，则用hundreds of，thousands of，millions of。
4）数词与其他词构成复合形容词时，其中的名词要用单数形式。如：an eight-cent-stamp， a three-month-old baby。
2．序数词
1）序数词表示顺序，使用时一般前面要加定冠词。基数词变序数词有一定的规律，下面的口诀可帮助你记忆：
基变序有规律，123特殊记。
th要从4加起，8减t，9去e。
ty变成tie，ve要用f替。
若要变为几十几，只变个位就可以。
2）有时序数词前不用定冠词，表示“再一、又一”的意思。如：
Soon the Greens had a second child--a son.很快格林夫妇又有了一个孩子——一个儿子。
3．分数，小数和百分比
1）表示分数时，分子用基数词，分母用序数词。当分子大于1时，分母须用复数形式。如：
1/2上读作one half或a half, 1/4读作one fourth或a quarter，2/3读作two-thirds, 3 2/5读作three and two-fifths。
2）读小数时，小数点前的基数词与前面所讲的基数词读法完全相同，小数点读作“point”，小数点后只需将数字一一读出。如15.07读作fifteen point zero seven。
3） 百分数的读法为：先读基数词，再读百分号。如5%读作five percent。
4．年份和日期
1）年份的读法为每两位数读一个词。如：
1950读作nineteen fifty
1800读作eighteen hundred
读作two thousand
2）日期的读法有两种
（1）先月后日，日子要读成序数词。如：9月29日可读作September (the) twenty-ninth
（2）先日后月，在月份之前加Of。 如：9月29日也可读作the twenty-ninth of September
3）年月日同时出现，年代放在最后，年代前用逗号隔开。如：2月1日可写成the first of February ,或February( the) first, 2005
5．时间和钟点
6:00读作six (o'clock)
7:30读作seven thirty／half past seven
9:45读作nine forty-five／a quarter to ten
2:15读作two fifteen／a quarter past two
6．编号的表达
1）事物名词（不加冠词）+基数词。如：Lesson One，Part Three，Channel Five，Gate Nine,，World War Ⅱ
2）定冠词+序数词+事物名词。如：the first lesson，the third part，the fifth channel，the ninth gate，the Second World War
7．加减乘除的英语表达
plus/and加，minus减，time/multiplied by乘，divided by除。如：
1）12 +8=？ How much is twelve plus/and eight?
2）40—11=29， Forty minus eleven is/equals twenty nine.
3）3×6 =18， Three times six is/equals eighteen.
4）56÷7=？ How much is fifty-six divided by seven?
篇2：英语数词语法讲解：数词的词形
数词，表示数量和顺序的词。数词具有名词性质，兼有形容词性质。
数词有基数词和序数词两类，基数词表示数量，序数词表示顺序。
基数词：one, two, four, …1, 2, 3……
序数词：first, second, third,fourth…第一，第二，第三，第四……
数词的词形
英语数词的构成很有规律性：
1)13-19的基数词在个位数上加-teen构成，-teen是10之意。
thirteen,fourteen, fifteen…
2)20-90的各十位整数都以ty结尾。
twenty,thirty, forty,sixty, seventy,eighty, ninety
3)21-99的个位数同1-9的个位数，在十位和个位之间加连字号“-”
twenty-one, twenty-two, twenty-three, twenty-four…
thirty-one, forty-one, fifty-one, …ninety-nine
4)三位数数词的百位和十位(没十位则和个位)之间要加and。
178 one hundred and seventy-eight
890 eight hundred and ninety-six
907 nine hundred and seven
990 nine hundred and ninety
5)在数字超过4位数时，每3位标一个“，”，以方便念。
2,121
8,023,286
9, 8 7 6, 5 4 3, 2 1 8
billion million thousand
十亿 百万 千
5)注意英语中没有“万，十万”的专门数词，必须把万念成10个千，十万念成100个千。初学者常在这两处念错。
26，000 应该念成twenty-six thousand
769,323应该念成seven hundred sixty-nine thousand three hundred and twenty-three
6)序数词除first, second, third外，其余都是在基数词后面加th上。
fourth, sixth, seventh, twenty-first,thirty-second…
注意十位整数的序数词，要先 改y为ie再加th，千万别让中间长出脚y来!
篇3：助动词语法讲解及练习题
一、助动词语法讲解
1. 助动词be的用法
1) be +现在分词，构成进行时态。例如：
They are having a meeting. 他们正在开会。
English is becoming more and more important. 英语现在越来越重要。
2) be + 过去分词，构成被动语态。例如：
The window was broken by Tom.. 窗户是汤姆打碎的。
English is taught throughout the world. 世界各地都教英语。
3) be + 动词不定式，可表示下列内容：
a. 表示最近、未来的计划或安排。例如：
He is to go to New York next week.. 他下周要去纽约。
We are to teach the freshmen. 我们要教新生。
说明： 这种用法也可以说成是一种将来时态表达法。
b. 表示命令。例如：
You are to explain this. 对此你要做出解释。
He is to come to the office this afternoon. 要他今天下午来办公室。
c. 征求意见。例如：
How am I to answer him? 我该怎样答复他?
Who is to go there? 谁该去那儿呢?
d. 表示相约、商定。例如：
We are to meet at the school gate at seven tomorrow morning. 我们明天早晨7点在校门口集合。
2. 助动词have的用法
1)have +过去分词，构成完成时态。例如：
He has left for London. 他已去了伦敦。
By the end of last month, they had finished half of their work. 上月未为止，他们已经完成工作的一半。
2)have + been +现在分词，构成完成进行时。例如：
I have been studying English for ten years. 我一直在学英语，已达十年之久。
3)have +been +过去分词，构成完成式被动语态。例如：
English has been taught in China for many years. 中国教英语已经多年。
3.助动词do 的用法
1)构成一般疑问句。例如：
Do you want to pass the CET? 你想通过大学英语测试吗?
Did you study German? 你们学过德语吗?
2)do + not 构成否定句。例如：
I do not want to be criticized. 我不想挨批评。
He doesn't like to study. 他不想学习。
In the past, many students did not know the importance of English.
过去，好多学生不知道英语的重要性。
3) 构成否定祈使句。例如：
Don't go there. 不要去那里。
Don't be so absent-minded. 不要这么心不在焉。
说明： 构成否定祈使句只用do，不用did和does。
4)放在动词原形前，加强该动词的语气。例如：
Do come to my birthday party. 一定来参加我的生日宴会。
I did go there. 我确实去那儿了。
I do miss you. 我确实想你。
5)用于倒装句。例如：
Never did I hear of such a thing. 我从未听说过这样的事情。
Only when we begin our college life do we realize the importance of English. 进了大学以后，我们才认识到英语的重要性。
说明： 引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。
6)用作代动词。例如：
---- Do you like Beijing? --你喜欢北京吗?
---- Yes, I do. --是的，喜欢。(do用作代动词，代替like Beijing.)
He knows how to drive a car, doesn't he? 他知道如何开车，对吧?
4. 助动词shall和will的用法
shall和will作为助动词可以与动词原形一起构成一般将来时。例如：
I shall study harder at English. 我将更加努力地学习英语。
He will go to Shanghai. 他要去上海。
说明：在过去的语法中，语法学家说shall用于第一人称，will 只用于第二、第三人称。现在，尤其是在口语中，will常用于第一人称，但shall只用于第一人称，如用于第二、第三人称，就失去助动词的意义，已变为情态动词，试比较:
He shall come. 他必须来。(shall有命令的意味。)
He will come. 他要来。(will只与动词原形构成一般将来时。)
5.助动词should, would的用法
1)should无词义，只是shall的过去形式，与动词原形构成过去将来时，只用于第一人称。例如：
I telephoned him yesterday to ask what I should do next week. 我昨天给他打电话，问他我下周干什么。
比较：“What shall I do next week?” I asked. “我下周干什么?”我问道。
可以说，shall变成间接引语时，变成了should。
2) would也无词义，是will的过去形式，与动词原形构成过去将来时，用于第二、第三人称。例如：
He said he would come. 他说他要来。
比较：“I will go,” he said. 他说：“我要去那儿。”变成间接引语，就成了He said he would come。原来的will变成would，go变成了come.。
6. 短语动词
动词加小品构成的起动词作用的短语叫短语动词。例如：
Turn off the radio. 把收音机关上。(turn off是短语动词)
短语动词的构成基本有下列几种：
1)动词+副词，如：black out;
2)动词+介词，如：look into;
3)动词+副词+介词，如：look forward to。构成短语动词的副词和介词都统称为小品词
