作业帮选择(主谓一致)
来源：学生作业帮 编辑：作业帮 分类：英语作业 时间：2024/05/08 05:25:54
a series of meetings _about the best way to market the new product.为什么是was held 不是were held
解题思路： a series of +复数名词做主语,谓语动词要用第三人称单数。
解题过程：
series 连续,系列(单复数同形),做主语时谓语动词根据series单复数概念决定,不根据of后的名词决定。
a series of 表示“一系列”用来修饰主语时，表示一个整体概念，谓语用单数形式。在语义上都强调的是“一个”整体，动词之所以用单数，原因就在这里。
请看下题:
A series of lectures on university study ______ to the freshmen enrolled this year.
A. have delivered B. has delivered
C. have been delivered D. has been delivered
此题选D。a series of +复数名词做主语,谓语动词要用第三人称单数; 讲座 'lectures'应该是动词 'deliver'的宾语,这里要用被动语态.D. has been delivered 符合上述两项要求,是正确答案;
A.have delivered 和B.has delivered 均为主动语态,不符合句子要求;
C.have been delivered 谓语动词是复数,不符合主谓一致原则.
最终答案：略
