中考英语主谓一致考点10大类
在there be句式中,动词be不仅有时态上的变化,而且有单复数的变化:确定其时态的方法是看句子意思和句中的时态状语或其他相关时态;确定其单复数的方法是看与动词be最靠近的名词是单数还是复数。
【例1】Look, there ________ many students on the playground at the moment. (浙江衢州中考题)
A. is B. are C. was D. were
解析:there be句式中的be与其后的所接名词(其实是用作主语)保持一致,故可排除A和C;再根据句中的look和at the moment可知,句子应用一般现在时,即答案选B。
【例2】—Why are you late, Jim?
—Because there ________ a lot of traffic when I came here. (江苏泰州中考题)
A. is B. are C. was D. were
解析:因traffic(交通)为不可数名词,故此处的there be句式中的be用单数is;再根据when I came here中的一般过去时可知,句子说的是过去的情况,故选C。
八、考查一段时间或一笔钱作主语时的主谓一致
当一段时间(如ten years)和一笔钱(如100 dollars)用作主语时,若是将其视为一个整体看待,其后的谓语动词应用单数。
【例1】— How soon can you finish this job?
— Two days ________ enough for me to finish the work. I need a week. (四川自贡中考题)
A. isn’t B. aren’t C. is D. are
解析:虽然句子主语two days为复数形式,但从句意来看,它在此是被作为一个整体看待的,故谓语动词应用单数,即可排除B和D;再根据句中的I need a week(我需要一周)可知,“两天”肯定是不够,故答案选A。
【例2】—How much is the pair of shoes?
—Twenty dollars ________ enough.(四川广安中考题)
A. is B. are C. am D. have
解析:根据句意,twenty dollars在此被看成一个整体,表示单数概念,故用is,即答案为A。
