题目内容
11.The number of students in this university grown quickly over the past ten years.( )| A. | have | B. | has | C. | is |
分析 过去的十年里,这所大学的学生数量增长很快.
解答 答案:B
根据"over the past ten years"可知,这句话的时态为现在完成时,现在完成时的构成为have/has+过去分词.通过分析句子成分可知,这句话的主语为"The number of students",表示"学生的数量",所以这里应该用助动词的单数形式has,答案为B
点评 做这样的题时要根据句中的现有词语,确定句子的时态,然后根据时态的构成选出正确的选项.
