小考英语专题复习第17课时 数 词[巧学妙记]基数词变序数词的口诀基变序，有规律，一般词尾加上­th。一、二、三特殊记，词尾字母t，d，d。八去t，九去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。【解析】根据题意，一周有七天，days是名词复数，所以应用基数词，排除B。而基数词前不用the，序数词前应用the，因此可排除A和C。【答案】D【解析】本题考查日期的表示法。“5月2日”应为“May2nd”或“the2ndofMay”。【答案】A考点闯关17 一、写出下列单词的序数词或基数词。1．把下列基数词改为序数词。(1)one—________(2)five—________(3)eight—________(4)twelve—________(5)thirty—________(6)sixteen—________(7)twenty­two—________(8)seventy­nine—____firstfiftheighthtwelfththirtiethsixteenthtwenty­secondseventy­ninth2．把下列序数词改为基数词。(9)third—________(10)seventh—________(11)sixth—________(12)second—________(13)fiftieth—________(14)sixty­first—_______threesevensixtwofiftysixty­one二、找出下列各组单词中不同类的一个，将序号填入题前括号内。( )3.A.thirdB．threeC．thirteenD．thirty( )4.A.oneB．firstC．twoD．seven( )5.A.sevenB．elevenC．eightD．twentieth( )6.A.firstB．secondC．elevenD．seventh( )7.A.fifthB．fiveC．fiftyD．fifteenABDCA三、单项选择。( )8.Marchis________monthoftheyear.A．athree B．thethird C．athird( )9.Theclassbeginsat________(8：05)．A．fivetoeightB．eightfiveC．fiveeight( )10.Eightplus(加)eightis________．A．sixteenB．sixty­fourC．one( )11.Thereare________Englishbooksforstudentsintheschoollibrary.A．fourhundredsandfiveB．fourhundredsfiveC．fourhundredandfive( )12.Thebridgeis________．A．fourmetreslongB．fourmetrelongC．four­metreslongBBACA( )13.Helivesin________．A．310roomB．room310C．Room310( )14.Thisismy________time(次)toplaythepiano.A．atsecondB．twoC．second( )15.The________dayoftheweekisSunday.A．firstB．oneC．third( )16.Thereare________daysinayear.A．threehundredssixty­fiveB．threehundredandsixty­fiveC．threehundredandsixtyfive( )17.Jackisin________．A．ThreeClass,OneGradeB．ClassThree,GradeOneC．GradeOne,ClassThreeCCABB四、根据实际情况用适当的数词填空。(填英文)18．Thereare________lettersinEnglishalphabet(字母表)．19．Thereare________daysinaweek.20．Thereare________hoursinaday.21．Thereare________minutesinanhour.22．Thursdayisthe________dayoftheweek.23．Thereare________daysinJanuary.twenty­sixseventwenty­foursixtyfifththirty­one五、改错题：找出下列各句中的一处错误，将序号写在括号内，并在后句的横线上改正。( )24.ThereisA sixBbooksinCthebag.________( )25.TodayAismyB elevenCbirthday.________( )26.I'mA ninthB yearsCold.________( )27.FebruaryAisthetwoBmonthoftheyearC.________( )28.ThereareeighthA booksBinmyCschoolbag.________AareCeleventhBnineBsecondAeight六、阅读短文，选择正确答案。LucyisanEnglishgirl.Sheisthirteen.Sheismyclassmate.Sheisagoodgirlandwearegoodfriends.MrWangisourChineseteacher.Heisagoodteacher.Lucyhasasister.HernameisLily.Sheisnotinourclass.SheisinClassTwo.HerChineseteacherisMrLi.Heisagoodteacher,too. ( )29.LucyandLilyare________.A．brothersB．sistersC．cousins( )30.HowoldisLucy?A．Sheisthirty.B．Sheisthethirteen.C．Sheisthirteen.( )31.MrWangisa________.A．ChineseteacherB．ChineseC．Lily'steacher( )32.WhoisLily'sChineseteacher?A．MrWan.B．MrLi.C．MrWang.( )33.AreLilyandLucyinthesameclass?A．Yes,theyare.B．No,sheisn't.C．No,theyaren't.BCABC
