(1)0—12单独记。如: zero, one, two, three等。
(2)13—19的词尾都是teen。如:fourteen, seventeen等,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,80—eighty等。
(4)“几十几”要加连字符号“-”。如:48-forty-eight, 97—ninety-seven等。考点一 数词的构成语法互动(四)┃数词(5)“几百几十”或者“几百几十几”在“百”后加and。如:156—one hundred and fifty-six, 509—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=three thousand six hundred and ten; 94,295=ninety-four thousand two hundred and ninety-five;274,350=two hundred and seventy-four thousand three hundred and fifty等。语法互动(四)┃数词   2.序数词的构成
(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i,再加“-eth”。如:thirty→thirtieth; fifty→fiftieth。
(4)第一百hundredth; 第一千thousandth; 第一百万millionth。
(5)20以上的非整十的基数词变序数词时,只变化个位数。如:twenty-one→twenty-first; one hundred and one→one hundred and first。语法互动(四)┃数词基数词变序数词的巧记口诀:
