followed by 的用法We sat and watched The Music Man followed by

followed by
意思是 come, go or take place after sb/sth else in space, time or order 就是使某事物在空间,时间或顺序上在他人或者他事物之后,
例如：The lightning was quickly followed by heavy thunder.闪电过后紧接着是响雷
follow还有跟随；追捕的意思,

还有沿着……的意思
比如 Follow this road until you get to the corner, then turn left. 沿着这条路走到拐角处, 然着向左转

比较常用的就是这些意思了 希望有所帮助

我是英语系的学生 请给分哦
首先 此题可以有两种理1.老师跟着同学进教室 那么 逻辑主语就是老师 老师和“跟”是主动 因此用Following 因为是主动 所以不用加BY
2.老师进教室,后面跟着学生 那么 逻辑主义是学生 所以逻辑主语与跟 是动宾关系 因此用followed by 有被动含义

你问的是follow的非谓语动词的用法：
following是表示主动的：如：
following Miss Li,i went into the meeting room.
我跟着李小姐后面,我走进了会议室.
followed是表示被动的：如：
followed by some boys,he went into the meeting room.
他身后跟着几个男孩子,走进了会议室.

A came to the classroom(who is) followed by B A跟在B后面进入了教室
A came to the classroom, following by B B跟在A后面进入了教室

是呀,不是在作谓语,是在作非谓语.eg.1.The singer was followed by many fans.(谓语） 2.There was a singer followed by many fans.(后置定语）

4.5％至5.5％的氧气30秒,接着, 21％的氧气30秒, 每天8小时（8 hour/day）,在日间
这一句该分拆来看：
30 seconds of 4.5% to 5.5% O2
followed by
30 seconds of 21% O2
for 8 h/d during the daytime
猜这是说每天在日间时间,8小时的供氧气分量及每节的时长.
h/d = hour/day 时/天
