2013版初中英语全程复习方略课件（语法专项案）四 数词（译林牛津版）

课件25张PPT。四、数词 考点一 基数词 【巧学妙记】巧记100以内的基数词
基数词不难记，找清规律很容易；十二以内词各异，
十三数到十九去，后加teen莫忘记；
二十、三十至九十，正式之后有-ty；
要说“几十几”，中间“-”别丢弃；
a hundred是“一百”，请你记住莫大意。 考点二 序数词 【温馨提示】
(1)序数词要加定冠词the，但若序数词前有形容词性物主代词或名词所有格时省略the。例如：
Tom made the mistake for the third time. = It was Tom’s third time to make the mistake. 这是汤姆第三次出错。(2)序数词前加a/an表示“又一，再一”。例如：
Even though the Greens have 3 children, they still want a fourth one.
尽管格林夫妇已有3个孩子，可他们还想再要一个。
(3) 序数词可以用阿拉伯数字和序数词拼写的最后两个字母简写。例如：
1st第一，2nd第二，3rd第三，4th第四。【巧学妙记】基数词变序数词规律
基变序，有规律，末尾加上-th。
一、二、三特殊记，面目全非要注意。
八加th，九去e，ve要用f替。
逢十改y为ie，后跟-th莫忘记。
若想表示几十几，只变个位就可以。 考点三 数词应用 Ⅰ. 用所给数词的适当形式填空
