语法复习 数词1.基数词的构成
(1)1—12单独记。如: one, two, three, four, five , six, seven,
eight, nine , ten ,eleven, tweleve。
(2)13—19的词尾都是teen。如: thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, 但13—thirteen,15—fifteen,18—eighteen需要特殊记。
(3)20以上的整十的基数词均以ty结尾。如:20—twenty,30—thirty,40—forty,50—fifty, 60 --sixty, 70---seventy, 80—eighty, 90----ninety 等。
(4)“几十几”中间要加连字符号“-”。如:48—forty-eight,
97—ninety-seven等。 中考考点 一 基数词 (5)“几百几十”或者“几百几十几”在“百”后加and。如:156读作
one hundred and fifty-six, 509读作five hundred and nine等。
(6)四位数或者四位数以上的基数词的拼写规律:用逗号从右
往左每三位加一个逗号,第一个逗号读作thousand(千),第二
个逗号读作million(百万),第三个逗号读作billion(十亿),
hundred后莫忘“and”。
如:3,610 读作 three thousand six hundred and ten;
94,295读作ninety-four thousand two hundred and ninetyfive;
14,274, 350读作fourteenmillion two hundred and seventy-four thousand three hundred and fifty等。2.序数词的构成, 一般在基数词后加th。
(1)“第一”、“第二”、“第三”分别是 first, second, third。
(2)“第四”到“第十九”除了fifth, eighth, ninth, twelfth是特殊的拼写外,其余的都在相应基数词后面加“-th”构成。如:fourth。
(3)20以上的整十的序数词由相应的基数词变y为ie,再加“-th”。如:thirty→thirtieth; fifty→fiftieth。
(4)第一百hundredth; 第一千thousandth; 第一百万millionth。
中考考点二 序数词 (5)20以上的非整十的基数词变序数词时,只变个位数。如:twenty-one→twenty-first; one hundred and one →one hundred and first。
基数词变序数词的巧记口诀:
一、二、三特殊记, first, second, third,
th从四加起, 八去t,九减e,f来把ve替,
遇到几十去y变ie加th,几十几只将个位改为序数词。
巧记序数词缩略式:阿拉伯数字+后两个字母
one--first --1st , two--second --2nd, three--third--3rd,
eighteen__eighteenth __18th
thirty--thirtieth--30th
twenty--four_twenty--fourth--24th

数,其后不加-s,也不与of连用;但若用于表示“数百、数千、
数百万”这样的笼统数目时,后面则加-s,并与of连用。
如 ,hundreds of几百, thousands of 几千 ,millions of几百万等。
