基数词变序数词
1)许多序数词是由相应的基数词后加词尾-th构成的,如four/fourth,sixteen/sixteenth;
twentieth,thirtieth,fortieth等表示整十的序数词,由相应的基数词将词尾y改为ie,再加-th构成。
几个常考的不规则变化序数词需注意:
ninth,twelfth,fortieth,ninetieth等。
(
2)非整十的多位数,将个位数变成序数词即可:
twenty-first(第21),thirty-sixth(第36),
ninety-ninth(第99),threehundredandsixty-fifth(第365)等。
3)序数词前通常要用定冠词,但当序数词前有形容词性物主代词时,通常省略其前的定冠词。
Todayismyfather’sfortiethbirthday.
4)序数词前一般要用定冠词the,如果序数词前用a或an时,则表示“又一;
再一”(没有具体范围的限制)。
Though
he
had
failed
twice,
wanted
to
try
a
third
time.
尽管他已失败了两次,他还想再试一次。
