英语句子连词 副词能放一起吗？

Question

就是An old man was counting his money in the front of the bank while suddenly a young man came running and knockedhim down.这句话对吗?

Answer 1

这句话对。
while是连接An old man was counting his money in the front of the bank和suddenly a young man came running and knockedhim down两句的。suddenly是后一句的状语，它和while无关系。
