单选题 .Political parties in the United States help to coordinate the campaigns of their members and A B organize the statewide and national conventions that mark election years. C D
【正确答案】 C
【答案解析】Key:C 分析:考点是平行结构。and连接平行结构,此处and 连接的是主语的两个并列谓语。应该都是不定式。C错。 改正: organizes ? organize 参考译文:美国的政党有助于协调其成员的活动,以及组织在大选年进行各州或者全国范围内的会议。
