完整版)小升初英语数词专项数词是用来表示数目或顺序的词语。
基数词和序数词是数词的两种类型。
基数词表示数量,而序数词则表示顺序。
基数词的构成有以下几种规则。
首先,1-12的基数词是独立的单词,例如:one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve。
其次,13-19的基数词以-teen结尾,例如:fourteen,seventeen等,但13,15,18较特殊,13—thirteen。
15—fifteen。
18—eighteen。
第三,20-90的整十位均以-ty结尾,例如:sixty,y,但20,30,40,50,80较特殊,20—twenty。
30—thirty。
40—forty。
50—fifty。
80—XXX,十位数与个位数之间要加连字符号"-",例如:enty-eight,y-six。
第五,百位和十位(若无十位则和个位)之间加and,例如:148—one hundred and forty-eight。
406—four hundred and six。
第六,hundred(百),thousand(千),n(百万),n(十亿)等前面即使有具体的数词,several。
some。
many也不能在它们的后面加-s,例如:six hundred,eight n。
如果表示不确定数目时,用XXX名词复数,前面不能再加数字。
第七,1000以上的数字,从后往前数每三位加一个逗号","第一个逗号前为千(thousand),第二个逗号前为百万(n),n(十亿)。
英语中无“万”这个词,我们可以用"几十个千(thousand)"表示几万,"几百个千(thousand)"表示"几十万"。
例如:2,510=two thousand five hundred and ten。
