另外还要注意序数词的用法:
1.在使用时一般要在序数词前加上定冠词THE来强调.
2.如果在有前后文的基础上,表达又有或再有的概念时,要把THE换成A.如:
He came late the first time,but he came even later a second time。
第一次他来晚了,第二次他又来晚了,甚至比第一次更晚.
3.在分数的英语表达中要注意:分子用基数词,分母用序数词;当分子大于一时分母用"复数"形式.如:
one fifth (五分之一);two fifths(五分之二)。
4.在有些名词后可以用基数词来表达序数词.如:
Number 5 ; Picture 6= the sixth picture
