1、主谓一致要点归纳英语句子中，要根据主语的人称和数来决定谓语动词的形式变化，这就叫主谓一致。它通常依据三项原则:1)语法一致;2)意义一致;3)就近一致。现分述如下:一、语法一致原则I.主语的人称决定谓语动词的形式。例如:I love music.She loves music.II.主语的数决定谓语动词的形式1.不可数名词、可数名词单数、单数代词作主语，用单数谓语形式；复数的名同、代词作主语，接复数谓语形式。例如:The work is important.They have gone to Chengdu.2.单个动名词、不定式或主语从句作主语，用单数谓语形式;一个以上的动名词、不定式或主语

4、ker and the writer have come.3.and前、后的单数词语有each,every,many，no等修饰时，仍作单数用。例如:Many a teacher and many a student is watching the football match on the playground.Every boy and every girl enjoys equal rights here.No teacher and no student is excused from taking part in the activity.IV.主语前、后加表数、量等的修饰语时:1.
