英语语法填空问题The headmaster went into the lab,________ (follow) b

用followed,这是过去分词短语作状语,逻辑主语是句子主语the headmaster,主语承受follow动作,用过去分词.至于问到的being followed是现在分词的被动形式,表示分词动作和谓语动作同时发生.§分词做状语时,逻辑主语就是句子的主语.也就是说,主语发出分词动作时,用现在分词,当主语承受分词动作时,用过去分词.如：Carrying a pen in her hand,the girl was thinking about a maths problem.
Carried by its mother,the baby stopped crying.
On the bus,I found an old man being stolen.
In the police station,I noticed a thief being questioned
最后两句就表示同时进行

你好！
这里填followed,作伴随状语
真诚为您服务！

因为校长是被两位外宾跟随的，所以这里用被动形式followed。
being followed强调是一种状态，而句子没有强调状态，只是普通的描述一个动作。

句中有went, 而follow 不是与之并列的，故用非谓语动词。又因headmaster与guest是被动关系，故用过去分词作伴随状语。希望能帮到你！

主语是the headmaster，followed过去分词做状语，表示被动

首先同意楼上回答
being followed动名词的话就是做主语，而这句话已经有主语the headmaster.句子用逗号隔开，主语与谓语动词主语一致，就用伴随状语。伴随状语有主被动之分，这里就是被动。
用being followed 情况举例：
Being followed by his sister all day made him angry.
不用担心...
