Module1语法讲练数词的用法外研版（2012）英语九年级下册

数词数词是表示数目多少或顺序先后的词。表示数目多少的数词叫基数词，表示顺序先后的数词叫序数词。1.基数词的用法(1)当hundred，thousand，million等词前面有具体数字时，词尾不加s，也不和of连用；当这些词前面没有具体数字时，其后要加s，并与of连用，表示“成百上千的/成千上万的/数百万的”。例：threehundredstudents(三百名学生)，thousandsofbirds(成千上万的鸟)(2)表示某人的年龄可以用“基数词+year(s)old”或者“attheageof+基数词”；整十位基数词的复数形式可以表示人的岁数或年代。例：inthe1980s(在二十世纪八十年代)，inherthirties(在她三十多岁时)(3)编号表达：一般用“名词+基数词”表示顺序，如Room203；如果数字较小，也可用“the+序数词+名词”，如thefirstlesson。2.序数词的用法(1)序数词通常由基数词加后缀th构成，还有一小部分为不规则变化。例：four→fourth,one→first,two→second,three→third(2)一般情况下，序数词前要用定冠词the。例：thefifthday(第五天)(3)当序数词前有形容词性物主代词或名词所有格时，定冠词the要省略。例：myfirstjob(我的第一份工作)(4)当序数词前有不定冠词a或an时，意为“再……又……”。例：Hetriedasecondtime.(他又试了一次。)(5)序数词缩写形式：数字+最后两个字母（如1st,2nd,3rd,4th…）。巧记基数词变序数词的规律：基数词，有规律，词尾加上th。一、二、三，特殊记，词尾字母t、d、d。八去t，九除e，ve要用f替。ty将y变成i，th前面有个e。若是碰到几十几，前用基来后用序。练习题习题一：基数词与序数词转换根据要求写出下列数词的对应形式。1.one(序数词)→________2.three(序数词)→________3.twelve(序数词)→________4.twenty(序数词)→________5.eight(序数词)→________6.ninth(基数词)→________7.fifth(基数词)→________8.second(基数词)→________9.thirtyfirst(基数词)→________10.onehundred(序数词)→________习题二：单项选择从A、B、C、D四个选项中选择最佳答案。1.Thereareover________studentsinourschool.A.threehundredsB.threehundredC.hundredofD.hundreds2.Mysisteris________.Sheishavingabirthdaypartytoday.A.twelveB.thetwelveC.twelfthD.thetwelfth3.Decemberisthe________monthoftheyear.A.twelveB.twelvethC.twelfthD.twelvieth4.________peopleetovisittheGreatWalleveryyear.A.ThousandofB.ThousandsofC.FivethousandsD.Fivethousandof5.Helivesonthe________floor.A.threeB.thirdC.thirdsD.thethree6.Thisismy________timetovisitBeijing.A.oneB.firstC.thefirstD.afirst7.Mygrandfatherisinhis________.A.seventyB.seventiesC.seventiethD.theseventieth8.Pleaseturnto________.A.pagetwentiethB.thepagetwentyC.pagetwentyD.twentiethpage9.Shegotthe________prizeinthepetition.A.oneB.firstC.theoneD.afirst10.The________questionismoredifficultthanthefirstone.A.twoB.secondC.twiceD.thetwo习题三：用所给词的适当形式填空1.Thisisher________(three)timetowinthegame.2.Thereareabouteight________(hundred)peopleinthehall.3.Myfatherisforty________(year)old.4.The________(five)lessonisveryeasy.5.________(thousand)oftreesareplantedeveryyear.6.Heisthe________(one)toarrivehere.7.Iwanttotrya________(two)time.8.Shebecameateacherattheageof________(twentytwo).9.Thebookhas________(ninety)pages.10.Tuesdayisthe________(two)dayoftheweek.习题四：完成句子根据汉语意思完成句子，每空一词。1.我们学校有九百名学生。Therearenine________studentsinourschool.2.今天是她二十岁生日。Todayisher________birthday.3.成千上万的人观看了这场比赛。________ofpeoplewatchedthematch.4.他住在第十二层。Helivesonthe________floor.5.这是我第二次来上海。Thisismy________timetoetoShanghai.6.我爷爷今年七十多岁了。Mygrandfatherisinhis________.7.请打开书第二十五页。Pleaseopenyourbooksat________________.8.她又试了一次，终于成功了。Shetried________________timeandsucceededatlast.9.二十世纪九十年代，这里还是个小村庄。Inthe________,itwasstillasmallvillage.10.三月是一年中的第三个月。Marchisthe________monthoftheyear.习题五：改错题找出下列句子中的错误并改正。1.Therearetwothousandsstudentsinourschool.2.ThisismythefirstvisittoJapan.3.Heisinthefifteen.4.Shewonthefirstprizeinhertwentybirthday.5.Ihavethreehundredsbooks.6.Februaryisthetwomonthoftheyear.7.Thousandspeopleattendedthemeeting.8.Heisasecondyearstudent,andI'minGradetwo.9.Room301isonthethreefloor.10.Mybrotheris10years.习题六：综合填空阅读短文，用括号内所给词的正确形式填空。Mygrandmotherisinher1________(seventy).Shehas2________(third)children–myfather,myauntandmyuncle.Myfatheristhe3________(one)child.Hewasbornin1975.Iam4________(twelve)yearsold,andI'minGrade5________(six).Todayismy6________(nine)birthday.Myfathergaveme7________(hundred)booksasagift!Iknowthat8________(thousand)ofchildrenaroundtheworldlovereading.Thisisthe9________(four)timeI'vereceivedsomanybooks.Iwilltrya10________(two)timetofinishreadingthemallthisyear.
