谁能帮我看看这句话到底有没有问题?
It is a kind of ending which you may find unexpected for the first time you read it,but after deeply thinking,you have to admit that it is real and reasonable.
这句话有没有语法问题啊?为什么我提交作文时总是说这句话语法不规范?若有,应该怎么修改?

答案

for the first time you have read it.
整个句子可以改成：Though it's a kind of ending which you may find unexpected when the first you have read it,you have to admit that is real and reasonable after deeply thinking.
