朋友已催，回信如下，大家看是凶多吉少还是凶少吉多？
Dear Prof. wang,

Thank you for your patience. One reviewer who had accepted the invitation, failed to submit their review so there was a delay while an alternative reviewer was sought. However we have now received comments from two reviewers and will be able to make a decision on your manuscript within one week.

Sincerely,
Jane，

依照AC的速度，估计是审稿人意见不统一。我觉得不要催，相信ACS的效率。

第三方仲裁或者审稿人拒审，编辑估计也急，现在你只有等等等
