题目内容
15.There ____ a big birthday cake at yesterday's party.( )| A. | was | B. | were | C. | is | D. | are |
分析 在昨天的聚会上有一个大的生日蛋糕.
解答 答案:A.
在there be句型中,be动词的单复数应用就近原则(即要看后面的名词来判断),如果这个名词是可数名词的单数或者不可数名词,就用be的单数is;如果这个名词是复数就用be的复数are;根据a big birthday cake.在这里cake可数名词单数形式,所以be动词用单数,yesterday是昨天,表示一个过去的时间,所以本句的时态应该是一般过去时,be动词的单数形式的过去式是was.故选A.
点评 在做题时先掌握考点,本题考点是there be 句型的系动词be的变化形式(应借助于后面的主语来判断即就近原则),根据其用法做出正确的选择.
