主谓一致的三个原则在英语中,句子的主语和谓语动词在人称和数上必须保持一致,并且大致遵循以下三个原则:1. 就近一致原则所谓就近一致原则,就是指句子的谓语动词同最近的主语在人称和数上保持一致。如:Not you but I am to blame. 不是你而是我应该受责。Not only you but also your teacher is supposed to go. 不仅你要去,而且你的也要去。2. 语法一致原则语法一致原则指的是谓语动词与主语在语法形式上保持一致,即主语是单数形式,动词用单数形式,主语是复数形式,动词用复数形式。如:The girls are busy packing. 姑娘们在忙着收拾东西。The last few winters have been very cold. 过去几个冬天都很冷。3. 意义一致原则意义一致原则则谓语动词的数取决于主语所表示的意义,而不是其语法形式。如:People are lying on the beach. 人们躺在海滩上。The steel works is closed for the holidays. 钢厂因放假关门了。
