如果要用英语表达"大家不敢靠近"，可以说"everyone is afraid to approach"或者"no one dares to approach"。这个说法源于人们对某种事物或者情况的恐惧，从而不敢靠近。

例如：

The old house on the hill has a reputation for being haunted, so everyone is afraid to approach it.
The aggressive dog in the park has bitten several people, so no one dares to approach it.

翻译：

那座山上的老房子有闹鬼的名声，所以大家都不敢靠近。
公园里那只攻击性强的狗咬了几个人，所以没人敢靠近它。
