單獨使用，后不接名詞提問物品價格【見考點1】howmany后接可數名詞復數對可數名詞數量提問表示數量多少的數詞叫做基數詞，如one,two,three等。(二)基數詞基數詞的拼寫考點(1)one—twelve,無規律可言，應逐一記憶。(2)thirteen—nineteen,表示“十幾”，在個位數后

加后綴-teen，讀作/ti?n/，但要注意下面幾個詞

的拼寫：thirteen(13),fifteen(15),eighteen(18)。(3)twenty到ninety,表示“幾十”，以-ty結尾，但需注意下面幾個詞的拼寫：twenty(20)，thirty(30)，forty(40)，fifty(50)，eighty(80)。(4)“幾十幾”的表達方法：用整十數加個位數表示，中間用連字符“-”把整十數和個位數連接起來。如：twenty-five(25)，sixty--eight(68)。(5)一百的表示方法為onehundred或ahundred。要表示“幾百”，用具體數字加上hundred,如fivehundred(500)，注意此時的hundred是單數形式。表示“幾百幾”時，要在百位數和十位數(或個位數)之間加and。如：onehundredandtwo(102)。基數詞的用法考點表示數量，置于名詞之前。Shehastwobrothers.她有兩個弟弟。表示編號，置于名詞之后。TheyareinClassFive.他們在五班。表示號碼。Hisphonenumberis337-5683.他的電話號碼是337-5683。表示時間。It's10：00now.

現在是10點。表示年齡。Mysisteris8yearsold.我妺妺8歲了。用于計算Twoandfourissix.

2加4等于6。考向(基數詞只能修飾可數名詞，要注意數詞和名詞在數上要保持一致。eg：onebanana一根香蕉fiveboys五個男孩

hundred,thousand(千)等的復數形式可表示不確定的數目。在這種情況下它們須用復數形式，且后面要加of。eg：hundredsofteachers數百位老師thousandsofstudents數千位學生【難點】Makesentencesinthechartwiththewordsinthethreeboxes.the
