well-off
释义：“生活富足的”，一般用来形容巨富以下、温饱以上的家庭经济状况及相应的社会地位。与rich和wealthy相比显得这个词要更温和一些，没有那么俗气。
例句：
The Tahoma family was well-off by comparison to most.
When it comes to terrorism and extremism, intelligence agencies in the U.S. and Europe have been grappling with a bewildering phenomenon---that a surprisingly large number of Islamic radicals are relatively well-off and well-educated Westerners.
