英语基数词变序数词口诀
基变序,有规律,词尾加上-th。
一,二,三,特殊记,词尾字母t,d,d。
八去t,九除e,ve要用f替,ty将y变成i,th前面有个e。
若是碰到几十几,前用基来后用序。
整十基数变序数,先把ty变成tie,要是遇上两位数,十位基数,个位序,th最后加上去。
一,二,三变字体;th从4上起;8加h,9减e;用f代ve;ty变为tie。
解析口诀:
one→first,two→second,three→third这三个词变化特殊,要单独记;eight→eighth,nine→ninth,八去t,九去e后再加-th;five→fifth,twelve→twelfth,五、十二把ve换成f再加-th;twenty→twentieth,thirty→thirtieth...整十先把词尾y改为ie再加-th。
两位数时则十位数用基数词,个位数用序数词,如:
twenty-first。
