twenty→twentieth?forty→fortieth?????
twentieth, thirtieth, fortieth, fiftieth, sixtieth, seventieth, eightieth, ninetieth
4) 基数词几十几变成序数词时,表示几十的数词不变,只把表示几的基数词变成序数词。例如：?
????twenty-one → twenty-first?? forty-five → forty-fifth?
5) 第一百、第一千、第一百万、第十亿都是在基数词后直接加?th构成。例如：第一百→hundredth??第一千→thousandth?第一百万→millionth??第十亿→billionth?
