《How much are these socks?》PPT課件15
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(gè)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 twentyfour
(5)三位數(shù)的詞需注意百位和十位之間加and。eg：
148 one hundred and fortyeight
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(gè)一個(gè)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，forty去掉字母u，thirty，fifty更出奇，十位數(shù)后個(gè)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。
