Panacea
What you think it means: A cure。你以为单词的含义是：治愈。What it really means: A cure for a lot of things。单词的真正含义是：万灵药。
This one is easy to confuse because the explanation is virtually the same even if the definitions are vastly different. A panacea is something that cures a lot of things all at once. For instance, penicillin is a panacea. It cures a bunch of diseases. The flu vaccine is not a panacea because it only protects against the flu.这个单词很容易混淆，因为即便定义迥异，解释起来实质还是一样的。Panacea(万灵药)能立刻治愈各种疾病。比如说，盘尼西林就是panacea(万灵药)，它能治疗很多疾病;而流感疫苗就不是panacea(万灵药)，因为它只预防流感。
