答案应该是B
The teacher came in,followed by a student.(老师进来,后面跟着一个学生.老师是被学生跟着, 所以后面用过去分词短语做伴随状语.变成定语从句就是The teacher came in,who was followed by a student.)去掉who was 就成了现在的答案.
There came a crack of thunder, followed by a flash of lighting. (一阵雷声传来,后面跟着一道闪电)
前面是一个倒装句.正常的语序应该是:a crack of thunder came there,雷声是被闪电跟着,所以还是用过去分词做伴随状语.变成定语从句就是,There came a crack of thunder, which was fllowed by a flash of lighting.
