这几个英语句子有语法问题吗?请一处一处改出来
She(Liu Mei) tried her best help this old woman.She asked a pliceman.He told her to take the No.72 bus.Liu Mei went to the old women to the hospital.When the old woman saw her husband,Liu Mei left the hospital.She did not wait their thanks.
远山和叶06可以解释一下，She tried her best help this old woman为什么改成She tried her best to help this old woman吗？要分析的具体一点。
还有，这句话中有什么固定短语吗？

Answer 1

her best to help
take NO.72
old woman(整个句子有逻辑错误,liu mei took the old woman to the hospital才对）
wait for their thanks
NO随便啦
