ixtwenty-seventwenty-eighttwenty-ninetwenty+one=twenty-one★十位数数词构成：整十位数数词后加个位数词，中间用连字符号“-”连接。Sayarhyme英语数词不难记，找出规律就容易。一至十

二词各异，一个一个单独记。后面加teen变十几，thirteen，fifteen看仔细。Eighteen只有一个t，两个音节念清晰。二十至九十后加ty，twenty不同重点记。Forty去掉字母u，thirty，fifty更出奇。十位数后个位数，表示数值几十几，按序排列不费力，

连字符号莫丢弃。巧学妙记加努力，hundred是你的好成绩！CanyousayitinEnglish?2132435465twenty-onethirty-twoforty-threefifty-foursixty-fiveLearn76879899100seventy-sixeighty-sev
