What about February?A: It has 28 days.
And a leap year makes it twenty-nine.When is your birthday? 你的生日是什么时候？
【巧解句构】本句是由when（意为“什么时候,何时”）引导的特殊疑问句，用来对“时间”进行提问。例如：
When will you have lunch? 你何时吃午饭？
When do you go to the store? 你何时去商店？
【要点剖析】birthday意为“生日,开始日”，它是由birth“出生”与day“天,日子”两个词组成的合成词。Language Points基数词变序数词英语中基数词变为序数词时，一般在基数词后加词尾-th，
但有几个词变化特殊，只要记住下面口诀，这些问题即可迎刃而解。? 一、二、三，单独记；八去t，九除e，?ve要用f替; 整十基数变序数，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。 补全对话PracticeA：___________________？
