Unit1 Lights, camera, action 1.2 Grammar：主谓一致 主谓一致的定义个三大原则 主谓一致是句子主语和谓语在“人称”和“数”方面保持一致，一般遵循三个原则：语法一致原则、意义一致原则和就近一致原则。 （一）语法一致原则 主语的单复数决定了谓语动词的单复数。 （1）动名词、动词不定式、从句、不定代词作主语时，谓语动词常用单数。 ①Smoking is a bad habit. 吸烟是一个坏习惯。 ②To have known you is a privilege. 认识了你真是荣幸。 ③what you can see here is that you get this interesting pattern. 现在你们可以看到这个有趣的图形。 ④Everything is in a complete mass, which drives people crazy.　 所有的事情都毫无头绪，让人发疯。 （2）主语后接介词短语或其他插入语，如with, together with, as well as, like, but, except, along with, rather than, including, in addition to等，谓语动词的数要与前面的主语保持一致。 ①Coursework, as well as exam results, is taken into account. 除考试结果外，课程作业也要计入成绩。 ②I think Tom, rather than you is to blame for the accident. 我认为是汤姆而不是你该为这起事故负责任。 ③The teacher, along with his students, was present at the meeting yesterday. 这个老师和他的学生都参加了昨天会议 （3）and, both...and...连接两个不同的主语，谓语动词用复数形式。 ①Mike and Sue are always rowing. 迈克和休总是吵架 ②Both Beijing and Shanghai are big cities. 北京和上海都是大都会。 注意：如果and连接两个单数可数名词或不可数
