(2)用to与past表示。
在半小时包括半小时以内用几分past几点

过了半小时用下一个钟点差几分
如7:45读成a quarter to eight; 9:50读成ten to ten;
基数词变序数词的方法
基变序有规律,结尾加上th; 一二三特殊例,结尾字母t、d(即first, second, third);
八去t, 九去e, ve要用f替(即eigh—eighth; nine—ninth; five-- fifth ;twelve—twelfth);
ty改y为ie后加th别忘记(即整十数如twenty—twentieth;forty—fortieth);
几十几十位为基个位为序(如第二十一为twenty-first)。
另外强调序数词前一定要加the。
