【2021·四川泸州·中考真题】—When was the Communist Party of China founded?
—In 1921. It’s her ______ birthday this year.
A.hundred
B.hundredth
C.hundreds of
D.the hundredth
【参考答案】B
【试题解析】句意:—中国共产党是什么时候成立的?—1921年。今年是她的第一百个生日。考查序数词。hundred百(基数词);hundredth百(序数词);hundreds of成百上千;the hundredth第一百个。根据“It’s her ... birthday this year.”可知,空格处表达“第一百个”生日,并且空格前有“her”修饰,空格处不需要其他限定词修饰。故选B。
此题考查基数词和序数词,大部分同学都掌握住了基数词的用法和写法,但是一些同学可能因为记不住序数词的形式而做错题。故掌握住基数词变序数词的规则很重要。
基数词的构成
(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。
20—twenty,30—thirty,40—forty,50—fifty,80—eighty等。
(4)"几十几"要加连字符号"-"。
48—forty-eight, 97—ninety-seven等。
(5)"几百几十"或者"几百几十几"在"百"后加and。
156—one hundred and fifty-six, 509—five 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),第三个逗号读作billion(十亿),hundred后莫忘"and"。
3,610=three thousand six hundred and ten;
94,295=ninety-four thousand two hundred and ninety-five;
