單獨使用，后不接名詞提問物品價格【見考點1】howmany后接可數(shù)名詞復數(shù)對可數(shù)名詞數(shù)量提問表示數(shù)量多少的數(shù)詞叫做基數(shù)詞，如one,two,three等。(二)基數(shù)詞基數(shù)詞的拼寫考點(1)one—twelve,無規(guī)律可言，應逐一記憶。(2)thirteen—nineteen,表示“十幾”，在個位數(shù)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(shù)加個位數(shù)表示，中間用連字符“-”把整十數(shù)和個位數(shù)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(shù)字加上hundred,如fivehundred(500)，注意此時的hundred是單數(shù)形式。表示“幾百幾”時，要在百位數(shù)和十位數(shù)(或個位數(shù))之間加and。如：onehundredandtwo(102)。基數(shù)詞的用法考點表示數(shù)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(xiàn)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?？枷?基數(shù)詞只能修飾可數(shù)名詞，要注意數(shù)詞和名詞在數(shù)上要保持一致。eg：onebanana一根香蕉fiveboys五個男孩

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