用hold your tongue表达“保持缄默”

如果有人让你hold your tongue，那意思就是让你闭嘴，别说了，尤其是在你说了不中听的话时。

• I‘m going to have to hold my tongue because I keep saying what I think and people get upset!
• I had to tell Jane to hold her tongue; what she was saying didn‘t help us move forward in our planning meeting.

值得注意的是，短语slip of the tongue的意思是口误、失言。

• I meant to tell her she was fun not fat; it was just a slip of the tongue!
