5、ifteen，18eighteen需要特殊记。 (3)20以上的整十的基数词均以ty结尾。 20twenty，30thirty，40forty，50fifty，80eighty等。 (4)“几十几”要加连字符号“”。 48fortyeight, 97ninetyseven等。 (5)“几百几十”或者“几百几十几”在“百”后加and。 156one hundred and fiftysix, 509five hundred and nine。 (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)，
6、第三个逗号读作billion(十亿)，hundred后莫忘“and”。 3,610three thousand six hundred and ten; 94,295ninetyfour thousand two hundred and ninetyfive； 274,350two hundred and seventyfour thousand three hundred and fifty等。2.序数词的构成first 1stsecond 2ndthird 3rdfourth 4thfifth 5thsixth 6thseventh 7theighth 8thninth 9thtenth

8、dred and first 101st (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：thirtythirtieth; fiftyfiftieth。 (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：twentyone
9、twentyfirst; one hundred and oneone hundred and first。基数词变序数词的巧记口诀：基数词变序数词的巧记口诀：基变序，有规律，一、二、三特殊记， first, second, third，从四开始加th, 八去t，九去e，五和十二变ve为f再加th，整十变y为ie再加th, 若想表示几十几，只变个位就可以。3.分数的构成 分数是由基数词作分子，序数词做分母构成的。除了分子是“1”的情况外，序数词都要用复数。 1/3 one third 7/9 seven ninths 注意注意 一些特殊的分数表达法：a half 二分之一 a quarter
10、=one fourth 四分之一 three quarters=three fourth 专项集训专项集训1. volunteers will give out leaflets to ask people to protect the wetlands. A. Two hundreds B. Hundreds of C. Two hundred of D. Hundred of2.
