巧学妙记1)序数词前一般要加定冠词the。2)序数词常用来修饰名词，但当名词前有形容词性物主代词等限定词时，序数词前不用定冠词the。序数词的用法Iliveonthesecondfloor.我住在二楼。Todayismyninthbirthday.今天是我的九岁生日。onefifth五分之一twothirds三分之二4)序数词前有时也可加不定冠词a/an，这时表示的不再是具体范围内的“第几”，而是表示在原有基础上的“又一个，另一个”。Ithinkyoumustdoitasecondtime.我觉得你必须再做一次。（已经做过一次了）3)表示分数时，分子用基数词，写在前面；分母用序数词，写在后面。当分子大于1的时候，表示分母的序数词要加s。3aMatchthequestionsandanswers.QuestionsAnswers1.WhenisJenny’sbirthday?__2.Whenaretheirbirthdays?__3.Whenisyourbrother’sbirthday?____4.IshisbirthdayinJuly?____a.No,it’sonthe6th.b.HerbirthdayisonMay24th.c.Yes,itis.d.TheirbirthdaysareinJanuary.5.IsyourbirthdayonFebruary1st?___e.It’sonJune16th.bdecaPresentation3bCompletetheconversationandpracticeitwithyourpartner.A:How_______areyou,Grace?B:_______twelve.A:And_______isyourbirthday?B:My__________isonMarch12th.HowaboutyouandTom?A:Well,mybirthdayis_____July5th,andTom’sbirthdayis_____December.oldI’m/Iamwhenbirthdayonin3cFindoutyourgroupmembers’birthdaysandages.Lineupfromtheyoungesttotheoldest.A:Howoldareyou,LiHai?B:I’mthirteenyearsold.A:Whenisyourbirthday?B:It’sonFebruary20th....年纪最小的，最年轻的年龄最大的twelve________nine________一、写出下列基数词对应的序数词first1one________ninth2twenty__________twelfth3twentieth4eight_________thirty-two____________eighth5thirty-second6Exercises二.用所给词的适当形式填空1.The_______(five)unitisveryinteresting.2.Doyouwanttogoto_______(Tim)birthdayparty?3.Todayishis________(three)birthday.4.Dave’swatchisthesameashis_________(brother).fifthTim’sthirdbrother’s1.—Who’sthewomanunderthetr
