【第一篇:基数词变序数词口诀】
基数词变序数词(之一)
基变序,有规律,
词尾字母th。①
八减t,九减e,
f要把ve替。②ty把y变成i,
记住th前有个e。③
①按:指first、second、third。
②按:指eight去掉t,nine去掉e,five和twelve去掉ve加上f。
⑦按:指twenty→twentieth等。
基数词变序数词(之二)
第一、二、三要全变,①
其余“th”加后边,⑧“th”里有例外,
你需格外记明白:
八减t,九减e,②
字母f代ve,④ty变tie。⑥
①one——first,two——second,three——third。
②four-fourth,seven-seventh,hundred-hundredth。
③eight——eighth,nine—ninth。
④five—fifth,twelve—twelfth。
⑤twenty—twentieth,sixty——sixtieth。
直接引语间接引语的记忆口诀、定语从句记忆口诀、被动语态的口诀
人称变更怎么办? “一主①、二宾②、三不变”③
若是自引自的话, 听者不变称不变。
注:①“一主”指在直接引语中的第一人称变为间接引语时,要和主句中的主语在人称上保持一致。如:
He sad,“I am forty,”→He said that he was forty.
②“二宾”指直接引语中的第二人称变为间接引语时,要和主句中的间接宾语保持人称一致。如:
He said,“Are you coming tomorrow?”→He asked me if I wascoming the next day.
③“三不变”指直接引语中的第三人称变为间接引语时,人称不变。如:
He said,“Is she an English teacher?”→He asked if she was an English teacher.
另外注意直接引语为复数,引述者主语为单数,间接引语主语相应变复数。如:
He said,“Are you interested in English?”→He asked me/us if Iwas/we were interested in English.
一般现、过用be done,be有人称、时、数变。
完成时态have done,被动将been加中间。
一般将来shall (will) do,被动变do为be done。
将来进行无被动,shall (will) be doing,
现在完成进行同,have (has) been doing。
现、过进行be doing, 被动be加being done。
情、助、有、是妥安排,一律随新主语变。
否定助后加not,疑问一助置主前。
主语恰是疑问词,直陈语序主在前。
一般情助加be done,双宾多将间宾变。
复合宾语宾变主,宾补、主补相应变。
【第二篇:数词的分类及表示】
一 数词的种类 数词分基数词和序数词
基数词是表示自然数列的词, 例如; one , two ,three,four.....
序数词是表示先后顺序的词, 例如: first, second ,third,fourth...
二 基数词和序数词的表示法
1.基数词单词的拼写:1~12为单词,13~19都以后缀-teen结尾,20至90这样的整十数都以后缀-ty结尾,其他基数词中间加连字符号“-”再按照上述的变化进行。
例:21→twenty-one 56-- fifty-six 85→eighty-five
三位数的构成为:几+百+and+末两位(或末一位)数
例:132→one hundred and thirty-two
205→two hundred and five
千以上的数字的读法:从后面往前,每三位数作为一个单位,分别为thousand, million.
32, 548, 652, 读作:thirty two million, five hundred and forty eight thousand, six hundredand fifty two
2. 序数词=基数词+th (1、2、3为 first, second, third)。但以下几种情况要注意:
1) fifth (第五),eighth (第八),ninth (第九),twelfth (第十二)
2) 以ty结尾的基数词变词尾为tieth
例:twenty→twentieth, ninety→ninetieth
3)复合序数词只需要将相应基数词中最后一位变成序数词,其余不变。
例:第二十一→twenty-first
第二百四十五→two hundred and forty-fifth
【第三篇:基数词、序数词的用法】
三 基数词、序数词的用法
1. hundred, thousand, million 与数字连用,表示一定量的具体数字,不用复数,但表示不定概念可用复数
例:three hundred people, millions of people
2. 基数词表示时刻。
例:7点 seven o‘clock, 7:20 seven twenty
3. 给某些事物编号
例:Lesson One=the first lesson
Bus No. 2 7月1日=July I (July Ist)
1996年6月3日=June 3, 1996=June the third, nineteen ninety-six
4. 有关分数表示法。分子是基数词,分母是序数词。当分子大于1时,分母就用复数。
例:I’ve read one-fifth of the books.
I‘ve finished three-fifths of the words.
5. 有关倍数表示法
两倍用twice, 三倍以上用数词+times, 要注意倍数在句子的位置。
例:The door is three times the size of this.
6. 十位数字(个位为零)的基数词以复数形式出现时,表示年代、年龄
例:She is a good-looking woman in her forties. (forties 指40-49岁之间)
【第四篇:数词练习题及解析】
四. 数词实练习题解析:
1. The English for 10,440 is .
A. ten thousand , four hundreds and forty
B. ten thousand, four hundred and forty
C. ten thousands, four hundred and forty
D. ten thousand and four hundred, forty
本题在于掌握千以上数字的读法,在千、百前面有数字,不加复数;百位、十位中间加and ,每三位为一组,再加相应的单位即可,故选B
2. of the workers in the factory is about two hundred, of them are women workers.
A. The number, first-third B. The number, one-third C. A number, half D. A number, threequarters
分数表达法前文阐述已经很多,应表示为one-third. 要区分the number of 与a number of , thenumber of 指“......的数量” ,谓语动词用单数;
a number of 意为“许多”,谓语动词为复数。故选B
3. --- Can you write the number eighty-five thousand , six hundred and twenty-six?
--- Yes, it is .
A. 85662 B. 85626 C. 85006 D. 85000
千以上的数字,从后往前三个数为一个单位,即从85之后顺次写出三个数即可,即626,连在一起即为85626。故选B.
4. About of the books in our school library arewritten in Chinese.
A. fouth-fifths B. four - fifth C. four -fifthsD.fourths-fifth
本题考查分数的表达法,分子用基数词,分母用序数词,当分子大于1,
分母用复数,因此它的表达法为four-fifths,故选C。
5. 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
百、千、百万等词与数字连用不用复数,因此不加s。其次表示百位数时要在百位和十位之间(无十位,则在百位和个位之间)加and ,再次在个位与十位之间要有连字符“-”,故本题选A
6. January is New Year’s Day.
A. one B. two C. the first D. the second
某月的几号要用序数词表示,读时序数词前要加the 。故选C
7. Take the turning on your night.

根据题意判断本题考第几个转弯处需用序数词,拼写正确的只有B
