3.其它⾮整⼗的两位数21—99是由整⼗位数加连字符“-”,再加个位数构成。

2)4-19都是在后面加上th,特殊的有fifth, eighth, ninth,twelfth。
3)20-90把y变成ie然后加th,如twentieth。
4)21-99的序数词变后面的个位数。
序数词可以用缩写,如1st, 2nd, 3rd ,4th…序数词的用法(1)序数词主要用作定语,前面要加定冠词,例如:The first truck is carrying a food baskets.John lives on the fifteenth floor.(2)序数词有时前面可加不定冠词来表示“再一”,“又一”这样的意思,例如:We'll have to do it a second time.Shall I ask him a third time?When I sat down,a fourthman rose to speak.(3)表示年,月,日时,年用基数词表示,日用序数词表示。

(8) 在…世纪:in the twenty-first centuryin the nineteenth century1. About ________ students in our class can describe that place in English.A. three-fifthsB. three-fifthC. third-fiveD. third-fifths答案:A。
该题考查的是分数的表示法。
分子用基数词表示,分母用序数词表示。
分子大于1时,分母应加-s,因此应选A。
2. Nine _______ pounds a week? That’svery good.A. hundred ofB. hundreds ofC. hundredsD. hundred答案:D。
