____個位十位__個位基數詞的規律總結基數詞記憶規則歌訣基數詞不難記，找出規律很容易：零至十二形各異，加上-teen為十幾；Thirteen，fifteen看仔細，eighteen只有一個；Twenty卻是很奇怪，forty本身也不乖，Eighty一起搞例外，跟著也把規則壞；十位后面是個位，表示數字“幾十幾”，表示“幾百幾十幾”，and常把百、十系。勤學妙記加練習，hundred就是你的好成績。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.
