“bury one's head in the sand”可不只是“把头埋进沙子里”的意思，还表达的意思是“逃避现实，完全忽略某件事，自欺欺人”。

【例句】
You're going to have to face the situation and not bury your head in the sand.
你要面对事实，不要自欺欺人。

You can bury your head in the sand if you want to, but Bruce is stealing, and sooner or later we’re going to have to deal with it.
如果你愿意，你可以面对现实，但是布鲁斯在偷东西，我们迟早要对付他。
