1.序数词前面一般要加定冠词the(或物主代词):
英语中的数词包括基数词和序数词两大类,为了便于同学们系统地复习数词,
现就小学阶段数词的主要内容作以下归纳。
一、基本构成
(一)基数词(表示几)
1.1—12的基数词是独立的单词,即:one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve。
2.13—19的基数词以-teen结尾,但13,15,18较特殊,13—thirteen 15—fifteen18—eighteen。
3.20—90的整十位均以-ty结尾。但20,30,40,50,80较特殊,20—twenty,30—thirty,40—forty,50—fifty,80—eighty。
4.十位数与个位数之间要加连字符号“-”,如:28twenty-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),thousand(千),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,
(二)序数词——由基数词转变而来,表示“这是第几个”
1.口诀巧记基数词变序数词:
“一、二、三,特殊记,(第一first第二second第三third)
八去“t”,九去“e”,(eight—eighth nine—ninth)
“ve”要用“f”替,(five—fifth,twelve—twelfth)
见y变成i和e,词尾加上th(twenty—twentieth,forty—fortieth)
若是遇到几十几,只变个位就可以。(twenty-five—twenty-fifth)
2.其余情况均在基数词后加th
3.序数词有时用缩写形式:
First缩写1st,twenty—second缩写22th.
二、基本用法
(一)基数词的基本用法
用基数词来修饰可数名词时,一定别忘了用该名词的复数形式。
如:十八个男孩eighteen boys
(二)序数词的基本用法Autumn is the third season in a year.
2.如果数字较长,序数词总避免使用,而且读的方法也常常简化:
第201房间:Room201第319页:page319
3.在谈编了号的东西时,我们可以用基数词表示顺序:
the first part------part one
三、特殊数字的表示法
(一)年月日表示法
1.年代前用in.
(in)1905读作(in)nineteen and five
(in)1800读作(in)eighteen hundred
2.月份开头第一个字母须大写,表示“在某月”时,月份前面用in。
(in)January Jan.(in)March Mar.(in)December Dec.
3.日期用序数词(前需要加the)表示;“在某日”,前面用介词on. (on)October the first
4.某年某月某日
in Sep.1954
on Oct.1,1949(读作on October the first,nineteen forty-nine)
(二)时刻表示法
1.在具体时刻前通常用at。如:(at)six or six o’clock
2.如说几点几分,常将时和分钟分别读出来,如:7:40读作seven forty 注:上午可以用am表示,下午用pm表示,例如:9.50am11.05pm
(三)一些数学加减的读法:
3+8=11three plus eight is eleven.9-7=2nine minus seven is two.
