题目内容
10.-My father will be back for their school's anniversary ceremony.-I see.That means they'll have a get-together with his classmates in years.
( )
| A. | twenty;twenty | B. | twentieth;twenty | ||
| C. | twenty;twentieth | D. | twentieth;twentieth |
分析 --我爸爸将将返校参加他们学校的二十周年庆典.
--我明白了.那就意味着20年后他将和他的同学们聚在一起.
解答 答案:B.
根据their school's anniversary ceremony,可知这里指学校二十周年庆典,即"第二十个周年庆典",所以第一空应用二十的序数词twentieth;再根据in years,可知这里是二十年后,表示数量用基数词twenty,故选B.
点评 英语中数词分为两种,序数词和基数词,序数词的构成是重点,即1)序数词1━19 除第一,第二,第三,第五,第八,第九,第十二变化不规则外,其余均由在基数词后加上-th. 2)十位整数的序数词的构成方法是,是将十位整数基数词的词尾-y 变成 i 再加-eth. 3)几十几的序数词,只是把个位数变成序数词,十位数不变. 序数词的用法:序数词主要用作定语,表语.前面要加定冠词 the.
