1. 这是什么词？
词：prone
英英释义：likely to do something or be affected by something, especially something bad
2. 为什么选这个词？
“prone”是个形容词，表示“易于…的” “很可能…的”，也就是说它经常可以用来替换 likely, inclined 等表示“有…可能/倾向”的词，是个在口语和写作中都高频实用的表达。
prone 最常见的用法是be prone to，后面常接有负向意义的名词或者动词。比如日本地形独特，是一个经常遭受地震或台风的国家，我们就可以说:
Japan is prone to earthquakes and typhoons.（be prone to 后接名词的用法）
或者：
Japan is prone to suffer earthquakes and typhoons. (be prone to 后接动词原形的用法）
许多人在接受测试的时候都很容易紧张不安，我们就可以说：
Most people are prone to anxiety during a test.
《经济学人》中就出现过许多这种用法，比如：
But in China and India, young women have been unusually prone to suicide.
prone 的另一个常见用法是与名词连用构成形容词，表示“易受…影响的”，和 be prone to 可以替换实用。比如像美式橄榄球、冰球等对抗性运动的球员往往很容易受伤，我们就可以说：
American football and ice hockey players are prone to injury.
或者：
American football and ice hockey players are injury-prone.
这样 -prone 的用法可以让表达简洁、灵活，比如上面的第一个例句也可以写成：
Japan is earthquake- and typhoon-prone. (注意这里连字符的用法：earthquake- and typhoon-prone 等于 earthquake-prone and typhoon-prone）
搭配：
be/seem/become prone 有倾向；好像易于；变得易于
leave sb/sth, make sb/sth 使...易于...
prone to 容易...的
翻译：
超重人群容易患高血压和高血糖。
Over-weight people are prone to high blood pressure and high blood sugar.
参考翻译:

场景：有好习惯的人更容易获得幸福感。
造句：People with good habits are prone to abtain happiness.
