小学六年级下英语数词复习讲解小升初专项练习题含答案

小学六年级下英语数词复习讲解小升初专项练习题含答案一、考点讲解数词是表示人或事物数目和顺序的词,分为基数词和序数词2大类,还有本身不表达数量但能形容数量多少的词。

1.基数词:表示数目多少的词。

2.序数词:表示先后顺序的词。

区别:基数词前面没有“the”,除1外,其他基数词后一般加可数名词复数;序数词前一定要有“the”,其后名词一般用单数形式,翻译为“第几”。

如:①I live on the third floor.(译为“我住在三楼”,指的是“第三层楼”)②My house has three floors.(译为“我家房子有三层楼”,指的是“楼层数有三个”)3.其他词表示数量多少的词。

例举如下:4.基数词的变化基数词1~12为特殊变化;13~19都是以teen结尾,其中13/15拼写特殊,需重点记忆;20/30/40...这样的逢十整数都是以ty结尾,二十几、三十几这样的数就用逢十整数加1~9,如25—twenty-five。

5.序数词的变化序数词1~3为特殊变化;4以后在基数词在词尾加th构成,注意five、nine、twelve拼写更特殊,需要单独记忆;在表达二十几、三十几。

这样的序数词时,前面不用变,只需把后面改成第一到第九即可,如32的序数词为:thirty-second。

6.对数量词的提问对基数词提问一般用How many/How old/ How long等;对序数词一般用Which提问。

二、专项练习(一)单项选择( )1. (沈阳市铁西区)September is month of a year.A. ninthB. the ninthC. the ninethD. nine( )2. There not milk in the bottle.A. is; someB. are; anyC. is; anyD. are; some( )3.
