就近原则是指一个句子的谓语动词与靠近的名词、代词在“人称、数”上一致(也就我们是我们常说的主谓一致)。比如说我们知道I 后面的be 动词要用 am, He 后面的be 动词要用is;但是Not only I but also he ________ interested in chemistry. 这个句子中的be动词是该填am 呢,还是is呢,还是are呢?答案是is,因为就近原则告诉我们,谓语动词的定位只要找与之最靠近的名词或代词,在这一题中就是he,所以后面的be动词就只需与它相关,那就是is.

采用就近原则的句型有:
1. There be 句型;
2. either…or 句型
3. neither…nor句型;
4. whether…or句型;
5. not only…but also句型;
