【句子】Knock yourself out literally. 【The Vampire Diaries-S1E2】【发音】[nɒk] [jə(r)'self] [aʊt] [ˈlɪtərəli] 【翻译】尽情High。【适用场合】knock out原意是：打倒；击败；knock yourself out 不是把自己打倒；而是 to become unconscious or to go to sleep. 这里指的是嗑药嗑high了，随便high。literally 就按照knock out字面含义那么high。瑶瑶老师微信公众号：YaoYao_English；关注后参加每日跟读，免费微信群纠音。
