《How much are these socks?》PPT課件15
1.基數詞
基數詞的寫(xiě)法：
(1)1～12，拼寫(xiě)和讀音沒(méi)有什么相似之處，無(wú)規律可言，應逐一進(jìn)行記憶。
(2)13～19，表示“十幾”，在個(gè)位數后加后綴teen，并且重音在后。注意(13)thirteen，(15)fifteen分別由three和five轉化而來(lái)；(18)eighteen是eight中加een而來(lái)。
(3)twenty～ninety整十以ty結尾。
(4)幾十幾要用連字符。
eg：24 twentyfour
(5)三位數的詞需注意百位和十位之間加and。eg：
148 one hundred and fortyeight
2.基數詞的巧記方法：
英語(yǔ)數詞不難記，
找出規律就容易。
零至十二樣各異，
一個(gè)一個(gè)單獨記，
后加teen變十幾，
thirteen，fifteen看仔細。
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，十位數后個(gè)位數，表示數值幾十幾，按序排列不費力，連字符號莫丟棄，巧學(xué)巧記加努力，hundred是你好成績(jì)。
