选 修 7 Units 3～ 专项语法十四 主谓一致 要点精析 一、语法一致原则 主语单复数决定谓语动词的单复数形式，即主语是单数，谓语用单数，主语是复数，谓语用复数。 Two students are waiting for you in your office. 两名学生在办公室等你。 二、意义一致原则 1．谓语动词用单数的情况 (1)由连词and连接的并列成分指的是同一概念，兼具身份或匹配出现。 The worker and writer is from Wuhan. 那个工人兼作家来自武汉。 (2)“no/each/every/many a＋单数名词＋and＋no/each/every/ many a＋单数名词”作主语。 Every man and every woman has a good reason to be proud of the work done by their fathers. 每一个人都很有理由为他们的父亲所从事的职业感到骄傲。 例 (2010·陕西，24)It is reported that many a new house________at present in the disaster area. A．are being built B．were being built C．was being built D．is being built 解析：句意：据报道，现在许多新房屋正在灾区兴建。由at present 可知本句要用现在进行时态，而当“many a＋可数名词”作主语时，谓语动词要用单数形式，尽管含有复数意义。 |
