关于“also”后是否加be动词的问题，需根据句子结构和时态来决定。以下是具体说明：
一、基本规则
also作为副词，通常放在be动词、助动词或情态动词之后，实义动词之前。
be动词的选用
be动词的形式（am/is/are）需根据主语的人称和数来决定，与是否加also无关。
二、具体用法示例
一般现在时
- 正确：
- The students are also reading books.
- I am also interested in music.
- 错误：
- The students also are reading books. [冗余]
- I also am interested in music. [冗余]
现在进行时
- 正确：
- They are also playing football.
- 错误：
- They are also playing footballing. [错误拼写]
一般过去时
- 正确：
- He was also at the meeting yesterday.
- 错误：
- He was also was at the meeting yesterday. [冗余]
三、注意事项
否定句与疑问句
also不用于否定句和疑问句。例如：
- 否定句：He is not only intelligent but also hardworking. [正确]
- 疑问句：Are they also coming to the party？ [正确]
- 错误：
- He is not also intelligent but also hardworking. [语法错误]
- Are they also not coming to the party？ [双重否定错误]
强调语气
为加强语气，also可置于句首：
- Also, we need to check the data again. [正确]
四、总结
加be动词： 当需要表达“也处于某种状态或进行某种动作”时。- 不加be动词
