这些是不该说的话?

5. The ball's in your court:
This phrase is usually thrown around (pun intended) to let others know that you've reached your limit with regard to handling a situation. "I've now done everything I can. After this, the ball's in your court."

6. Drill down:
This is too often used to denote the vigor with which a person or team will be pursuing an objective. "Yes, Bob and I are really going to drill down on that."

The following three made my list thanks to their redundancy:

7. I, personally:
Since something that is said by you is, by definition, personal, I see no need to include both words. For example, when you take the "personally" out of the following sentence, the meaning doesn't change. "Well, I, personally, don't think that X should take precedence over Y."

8. Quite unique (and its compatriots "very unique," "really unique" and "most unique"): unique这个定义本来是不分等级的
Despite the fact that things that are unique can't be qualified, I see this all the time. "Our store has the most unique items." Um ... no. You can, however, say, "Our store is filled with unique items." I have no trouble with that.

9. Past history:
This one drives me wild every time I hear it, "Well, based on past history ..." History is, by definition, something that occurred in the past, so why on earth say "past"?

And, finally, the most overused phrase in a business context:

10. Urgent (and its frequent companion "crisis"):
I include these because, as I'm sure you've discovered, the use of either, or both, of these words does little to resolve what might be going on. Instead, they either ratchet up the tension or make others wonder why you are so out of control. What do I recommend you use instead? I would substitute the use of "immediate" for "urgent," and "situation" for "crisis," as both convey the need for action but leave others room to bring their own skills and intelligence to bear -- while reflecting well on your own.
