1、今天我们讲数词数词一去二三里，烟村四五家。亭台六七座，八九十枝花。数词数词：表示数目的词数词基数词序数词数词其他数词相关数词基数词强调数目多少的数词one,two,three,four,five,six,seven,eight,nine,ten一、二、三、四、五、六、七、八、九、十数词基数词的用法：1、除了one以外，数词后面都要接可数名词且为可数名词复数;Example:There is one chalk on the table.There are two/three/four/five/six/seven/eight/nine/ten chalks on the table.数词基数词
2、的用法：2、如hundred，thousand，million，billion四个词一般只有两种用法：A、several/基数词+h/t/m/b+名词复数；B、h/t/m/b+s+of；其中：A表示几百、几千、几百万、几十亿的意思；B表示数以百计、数以千计、数以百万计、数以十亿记的意思；数词Example:The projector costs 4 hundred yuan.The Huawei sells 5 thousand yuan.20 hamburgers needs a hundred yuan.There are hundreds of residents in Xiaodian

5、and again.数词序数词的用法：3、用来表示分数时，基数词在前，序数词在后；其中基数词为one时，序数词用单数；基数词为one以上时，序数词用复数；这里给出几个分数表达的示例：One fourth,three fourthsOne fifth,two fifths,four fifths.数词序数词的用法：4、单纯表示第几名时，不需要加任何冠词；Example:I am first.Despite his being second,I think hes truly first from my view.数词其他数词相关：年龄的表示:基数词+years oldAt the age of+
