單獨(dú)使用，后不接名詞提問物品價格【見考點(diǎn)1】howmany后接可數(shù)名詞復(fù)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(diǎn)(1)one—twelve,無規(guī)律可言，應(yīng)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(jié)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(dá)方法：用整十?dāng)?shù)加個位數(shù)表示，中間用連字符“-”把整十?dāng)?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)?；鶖?shù)詞的用法考點(diǎn)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.

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(fù)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(fù)數(shù)形式，且后面要加of。eg：hundredsofteachers數(shù)百位老師thousandsofstudents數(shù)千位學(xué)生【難點(diǎn)】Makesentencesinthechartwiththewordsinthethreeboxes.the
