points4.twenty~ninety(20-90)表示“幾十”，幾十的整十位數是在個位數后加后綴-ty,讀[ti]。但要注意加了-ty之后，個位數上的聽定就有變化。eg：twenty(20),thirty(30),forty(40),fifty(50)...5.21-29直到91-99表示“幾十幾”，用整數十位數加個位數，中間用連字符“-”把整十位數加個位數，中間用連字符“-”把整十位數和個位數連起來。eg：twenty-three(23);thirty-seven(37);forty-five(45);fifty-two(52);sixty-one(61);

seventy-three(73);eighty-four(84);ninety-nine(99).6.onehundred“一百”，表示“一百”用ahundred。要表示200-900，用“數詞（two至nine）+hundred”構成。在此結構中，無論“幾百”，hundred都不能加-s變復數形式。7.hundredsof+復數名詞或代詞賓格是固定結構，表示“數以百計的”、“成千上萬的”，是個模糊數字，不是具體數字。在此結構中，hundredsof前面不能加數詞，hundredsof后面只能用復數名詞或復數代詞賓格形式。eg：hundredsofteachers成百上千的教師

hundredsofthem他/她/它們中數以百計的（人和物）1)表示數量，置于名詞前。2)表示編號，置于名詞后。名詞和基數詞首字母通常大寫。Ihavefiveapples.我有五個蘋果。I'minClassTwo,GradeSeven.我在七年級二班?；鶖翟~的用法數詞是表示數量或順序的詞，可分為基數詞和序數詞兩種。表示數目多少的詞叫基數詞，如one,two,three等?；鶖翟~可指代或修飾可數名詞。Languagepoints3)表示號碼。4)表示年齡。5)表示時間。6)表示計算。我的電話號碼是。Myfatherisfortynow.我的爸爸四十歲了。It'seighttwentynow.現在是八點二十分。Fiveandthreeiseight.五加三等于八。Languagepoints數詞“幾十幾”

(1)表達“幾十幾”用:

“幾十”+連字符“-”+“幾”37→thirty-seven;

98→ninety-eight(2)“幾十幾”是一個單詞,不能漏掉連字符。shoppingDemonstratives（指示詞）PricesStructures（句型）ColorsClothesthe,this,that,these,thosebig-smalllong-shortyuan,dollar(s)numbersblack,white,green,red,blue,yellow,purple,brownT-shirt,sweater,skirt,hat,jacket,socks,shorts,shoes,trousersA:HowmuchisthisshortredT-shirt？B:It’ssevenyuan.A:Howmucharethoseblackshoes?B:They’reninedollars.Sizes(大小)我都學會了!本課句型Summary一、WritethenumbersinEnglish．1.Myuncleis____________(25)yearsold．2.--Howmuchisthishat?--It’s_________(11)dollars．3.Myteacherisonly__________(22)yearsold．4.Theyhave_______(12)balls．5._______(15)and_________(13)is____________(28)．twenty-fiveeleventwenty-twotwelveFifteenthirteentwenty-eightExercises二、選擇填空。1.–________istheTV?–It’s2000yuan.A.Howmany
