【阅读原文】 标题：What Experts Want to Know About the Russia Plague Scare
Missing details about the death of a lab worker, including the cause, are worrying scientists.
正文：A 28-year-old worker at a research laboratory in Siberia recently died of pneumonia. The facility studies plague, among other pathogens,raising fears that she had been exposed at the laboratory.But Russian health officials so far have not linked the death of the worker,Darya Shipilova, to infection with Yersinia pestis, the bacterium that causes plague. And despite early reports that dozens had been quarantined near the research facility, health officials said that there was no risk of an epidemic.
知识点：【die of】 /daɪ əv/ 短语 英文释义：To die of something means to die because of it. It is used mainly when the cause is a disease, illness, or a condition inside the body (e.g. die of cancer, die of pneumonia, die of hunger). "Die from" is also correct and is more often used when the cause is an external event such as an injury, accident, or wound. 英文释义：to die of sth = 因（某种疾病、病症、饥饿、寒冷等）而死。die of 与 die from 意思几乎相同，区别主要在语义倾向——若病因来自身体内部（疾病、饥饿、衰老、失血等），用of 更地道；若来自外部事件（事故、枪伤、坠楼、中毒等），用from 更常见。 （本文特指：首句a 28-year-old worker ... recently died of pneumonia —— 作者用 of 而不是 from，恰恰在强调"死因是某种疾病"，为后文"到底是普通肺炎还是鼠疫"的悬念铺路。一个介词，就把"身体内部病变"这层意思钉住了） 核心搭配：die of cancer/a heart attack/pneumonia/hunger/thirst（of +疾病/身体状态）、die from injuries/wounds/a crash（from + 外部事件）、to die of a broken heart（心碎而死——文学化表达）、would rather die than...（宁死也不……）、die of boredom/embarrassment（无聊死了/尴尬死了——口语夸张用法） · Her father died of cancer three years ago.她父亲三年前死于癌症。 · In fairy tales, people often die of a broken heart.童话里，人们常常因为心碎而死。
