____个位十位__个位基数词的规律总结基数词记忆规则歌诀基数词不难记，找出规律很容易：零至十二形各异，加上-teen为十几；Thirteen，fifteen看仔细，eighteen只有一个；Twenty却是很奇怪，forty本身也不乖，Eighty一起搞例外，跟着也把规则坏；十位后面是个位，表示数字“几十几”，表示“几百几十几”，and常把百、十系。勤学妙记加练习，hundred就是你的好成绩。1aListenandrepeat.1cListenandcirclethenumbersyouhearin1a.10111213141516171819202122232425262728293031PracticeListenandcirclethenumbersyouhearin1a.Enrichyourlifetoday,yesterdayisowismystery1c1bWritethenumbersin1anexttothecorrectwords.Whichrowsofnumbersareinthewrongplaces?Doit!ten___eleven___twelve___thirteen___fourteen___twenty-five____twenty-six_____twenty-seven____twenty-eight____twenty-nine____twenty____twenty-one____twenty-two____twenty-three_____twenty-four____fifteen______sixteen______seventeen______eighteen_____nineteen_____thirty____thirty-one_____10111213142526272829202122232415161718193031Row2shouldberow4;row4shouldberow2.√1dListenagain.CirclethethingsinthepicturethatKateandhermomtalkabout.Check(√)thethingKatebuys.Readtheconversation.Mom:Oh,look!Ilikethatbluesweater.Howmuchisit?Kate:Fifteendollars.Oh,Ilikethesesocks.Mom:Oh,no.Idon’tlikered.Kate:DoyoulikethisT-shirt?Mom:Yes,Ido,butit’selevendollars.Kate:Oh,howmuchisthegreensweater?Mom:It’stwentydollars.Butyouhaveagreensweater.Kate:Mmm.Mom:Oh,doyoulikethesetrousers?Kate:Oh,yes.Howmucharethey?Mom:Onlysixteendollars.Kate:OK,I’lltakethem.While-readingReadtheadagainandanswerthequestions.Scanning1.CanyoubuybluesweatersinMr.Cool'sClothesStore?____________________________________2.Whichischeaper,purpleskirtsorblackshoes?____________________________________3.Howmucharesixpairsofsocks?____________________________________No,Ican't.Purpleskirts.Fourdollars.Enrichyourlifetoday,yesterdayisowismysteryFinishtheblank.Mom:Oh,look!Ilikethat______________.Howmuchisit?Kate:__________dollars.Oh,Ilikethese___________.Mom:Oh,no.Idon'tlikered.Kate:Doyoulikethis_________?Mom:Mmm,yes,Ido,butit's__________dollars.Kate:Oh.Howmuchisthe_________________?Mom:It's__________dollars.Butyouhaveagreensweater.Kate:Mmm.Mom:Oh,doyoulikethese_____________?Kate:Oh,yes.Howmucharethey?Mom:Only___________dollars.Kate:OK,I'lltakethem.bluesweaterFifteensocksT-shirtelevengreensweatertwentytrouserssixteen1eAskandanswerquestionsaboutthethingsin1b.
