单独使用，后不接名词提问物品价格【见考点1】howmany后接可数名词复数对可数名词数量提问表示数量多少的数词叫做基数词，如one,two,three等。(二)基数词基数词的拼写考点(1)one—twelve,无规律可言，应逐一记忆。(2)thirteen—nineteen,表示“十几”，在个位数后

加后缀­teen，读作/tiːn/，但要注意下面几个词

的拼写：thirteen(13),fifteen(15),eighteen(18)。(3)twenty到ninety,表示“几十”，以­ty结尾，但需注意下面几个词的拼写：twenty(20)，thirty(30)，forty(40)，fifty(50)，eighty(80)。(4)“几十几”的表达方法：用整十数加个位数表示，中间用连字符“­”把整十数和个位数连接起来。如：twenty­five(25)，sixty-­eight(68)。(5)一百的表示方法为onehundred或ahundred。要表示“几百”，用具体数字加上hundred,如fivehundred(500)，注意此时的hundred是单数形式。表示“几百几”时，要在百位数和十位数(或个位数)之间加and。如：onehundredandtwo(102)。基数词的用法考点表示数量，置于名词之前。Shehastwobrothers.她有两个弟弟。表示编号，置于名词之后。TheyareinClassFive.他们在五班。表示号码。Hisphonenumberis337­5683.他的电话号码是337­5683。表示时间。It's10：00now.

现在是10点。表示年龄。Mysisteris8yearsold.我妺妺8岁了。用于计算Twoandfourissix.

2加4等于6。考向(基数词只能修饰可数名词，要注意数词和名词在数上要保持一致。eg：onebanana一根香蕉fiveboys五个男孩

hundred,thousand(千)等的复数形式可表示不确定的数目。在这种情况下它们须用复数形式，且后面要加of。eg：hundredsofteachers数百位老师thousandsofstudents数千位学生【难点】Makesentencesinthechartwiththewordsinthethreeboxes.the
