each与be动词的搭配使用规则如下：
each作主语时，必须置于be动词、助动词或情态动词之后，行为动词之前。例如：
- Each student has a unique identifier.
- The teacher praised each student for their effort.
与every的对比
- every是形容词，只能作定语修饰单数名词，表示整体概念（如：every member of the team）。 - each是形容词或代词，可用作主语、宾语、定语等，强调个体（如：each member of the team）。3. 常见搭配示例
- each + of短语： - Each of the students submitted their assignments on time. - each与动词顺序
- The company rewards each employee for outstanding performance.
注意：
当each与of短语连用时，of短语需置于each之后。例如：
Each of the books on the shelf is well-loved.
通过以上规则，可以避免混淆并正确使用each。
