“主谓一致”是指句子的谓语动词与主语在“人称”和“数”上保持一致。即主语是复数，谓语也用复数形式，如are, were, have等; 主语是单数，谓语要用单数形式，如：is, was, has等。
在具体处理一致关系时可遵循以下三原则: 意义一致、就近一致、语法一致。 (Meaning Agreement, Adjacent Agreement , Grammar Agreement)
I.语法一致(Grammar Agreement):
1. I often ______( help/helps ) him and he often______( help/ helps ) me.
2. I _____ (is / am ) seventeen, she _____ ( is / are ) sixteen.
3. Two girls ______(are/were) standing on the corner now.
一、主语要和谓语动词保持人称和数的一致。主语为单数形式，谓语动词就采用单数形式；主语为复数形式，谓语动词也就采用复数形式。
