题目内容
1.To finish the task,we've tried three times,and after dinner we'll try time.( )| A. | the fourth | B. | a fourth | C. | fourth | D. | four |
分析 为了完成这项任务,我们已经尝试了三次,在晚餐后,我们将再尝试一次.
解答 答案:B;序数词前加不定冠词带有"再""又"之意,在第三次基础上又一次,用不定冠词a;根据前面的叙述we've tried three times,我们已经尝试了三次,可知该空应填a fourth time;指再一次.故选B.
点评 掌握序数词的表达是解题的关键;还要根据语境,细读选项,然后通过题干中的已供信息,捕捉到解题线索.
