小学英语语法知识要点总结1

  一、序数词——由基数词转变而来,表示“这是第几个”

  1.口诀巧记基数词变序数词:“一、二、三,要全变;其余都加th;th里有例外;八去“t”;九去“e”;“ve”要用“f”替,见“y”变成“i”和“e”,词尾加上“th”;若是遇到几十几,只变个位就可以。”第一、第二、第三分别:first,second,third,eight—eighth nine—ninth,five—fifth,twelve—twelfth,twenty—twentieth,forty—fortieth,twenty-five—twenty-fifth。

  2.序数词有时用缩写形式:

  *数字+序数词末尾两个字母(只有1st,2nd;3rd为特殊形式,其他都是th)

  二、序数词的基本用法

  1.序数词在句子中时,前面一般要加定冠词:

  如:I like the second dog.

  2.有时前面可以加一个不定冠词a/an来表示“再一”, “又一”这样的意思:

  We’ll have to do it a second time.

  3.基数词也可以表示顺序,要将基数词放在名词之后:

  the first part------part one

  the third lesson------lesson three
