notice一定要放在前面，怎么改？

1 Notice / remember that John never apologies to Grace,which
is one of the factors THAT lead to the conflict afterwards
2 Notice / remember that one of the factors that lead to the conflict afterwards is that John never apologizes to Grace.

notice that one of the reasons that lead to the conflict afterwards is that john never apologies to Grace.

这是祈使句Notice谓语动词，that后面都是宾语从句，其中包含着两个which引导的两个定语从句。没什么要改的。很通顺。
