there exsisted a certain doubt among the students as to the necessity of the work
这里there exsisted ,用it exsisted 也通啊,为什么不能用,如果硬是要用it该怎么改

这个是一个句式而已,就是外国人有这样用的
there be 句型中的be 可以用exist代替,表示事物静止、存在、有等.
不懂欢迎追问
再问：如果硬是要用it该怎么改
再答：不能换成it existed。。这个不能表达有的意思，而it不具备那个功能～这句话的意思是学生中间存在普遍的怀疑就是关于这个工作的必要性问题。学习语言关键是要有模仿能力，创造语言的新用法不是学习语言的途径，不过质疑是好的
