1.基數(shù)詞基數(shù)詞的寫法:(1)1~12,拼寫和讀音沒有什么相似之處,無規(guī)律可言,應(yīng)逐一進(jìn)行記憶。(2)13~19,表示“十幾”,在個位數(shù)后加后綴-teen,并且重音在后。注意(13)thirteen,(15)fifteen分別由three和five轉(zhuǎn)化而來;(18)eighteen是eight中加-een而來。(3)twenty~ninety整十以-ty結(jié)尾。 (4)幾十幾要用連字符。eg:24 twenty-fur(5)三位數(shù)的詞需注意百位和十位之間加and。eg:148 ne hundred and frty-eight
2.基數(shù)詞的巧記方法:英語數(shù)詞不難記,找出規(guī)律就容易。零至十二樣各異,一個一個單獨(dú)記,后加teen變十幾,thirteen,fifteen看仔細(xì)。eight原本就有t,eighteen只缺een。二十至九十后加ty,twenty不同重點(diǎn)記,frty去掉字母u,thirty,fifty更出奇,十位數(shù)后個位數(shù),表示數(shù)值幾十幾,按序排列不費(fèi)力,連字符號莫丟棄,巧學(xué)巧記加努力,hundred是你好成績。
