基数词到序数词的变化一二三单独记；八去 t，九除e，?ve要用f替，整十基变序，先把ty变成tie；要是遇到两位数，十位基数个位序，th最后加上去。
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。Review the Ordinal Numbers.1st first 2nd second 3rd third 4th fourth

I went to bed after I had finished my homework.(在……后)
He has worked in the factory since it opened in 1992.(从……起)
I’ll give him the book as soon as I see him.(一……就……)
注意1、when 和while区别
when后面的动词可以是延续性动词，也可以是非延续性动词。 while意思是“当……的时候”，由它引起的从句中必须用动词be、延续性动词或动词的进行时态，而不可用终止性动词。如：
I was walking in the street when the UFO landed.
He came to see me while I was having dinner.
while 还可以表示两者同时进行。
I was doing my homework while my parents were watching TV.
2.until和till
均可引起时间状语从句，表示“直到某时为止”，当主句动词为延续性动词时常用肯定式，当主句动词为终止性动词时常用否定式，如：
He kept working until (till) it began to rain.
He didn’t go to bed until (till) he finished his homework.
(他直到做完作业才上床睡觉。)
区别：
till和until用作连词或介词均可表示“直到……为止”，但放在句首时一般不用till而用until，如：
Until then, I knew nothing about it.
Until it began to rain, they kept on working in the field.
