(2) This is Alan’s (twelve) birthday. (3) January is the (one) month of the year. ninth twelfth first 序数词的用法： 一般情况下，序数词要加定冠词the。但当序数词前有物主代词(his, her…)、指示代词(this, that…)等修饰时，则不必再用the。 e.g. on the third floor 在三楼 on his twelfth birthday 在他十二岁生日这天 the first one 第一个 第一本书 the first book 我的第一本书 序数词+单数名词 my first book 第二个 the second one 第二个女孩 the second girl 他的第三支笔 his third pen 她的第四个问题 her fourth question 第二次 the second time 第五课 the fifth lesson Ⅰ. 用所给词的适当形式填空 March 6th is my (twenty) birthday. 2. I’m the (one) student to come here. 3. Mike and Tom (be) 13 years old. 4. Today is (Bob) birthday. 5.
