喉嚨不舒服怎麼說 Have a Frog in One's Throat

喉嚨不舒服怎麼說 Have a Frog in One's Throat



frog是「青蛙」,throat指「喉嚨」,have a frog in one's throat字面意思是「某人的喉嚨裡有青蛙」,實則用來形容某人「喉嚨不舒服」。類似的用法有:raspyhoarsehave a sore throat.。這個俚語的來源有好幾種說法,最具可信度的解釋就只是因為喉嚨痛時,發出的聲音聽起來跟蛙鳴聲很像。

提早偵測流感的方法

提早偵測流感的方法

I've spent most of the week with the flu. I'd heard flu season was starting early this year, but I wasn't prepared for it to be this early, in part because predictions for flu outbreaks are still not that precise—especially in germy places like here in New York City.

But a new approach, borrowing real-time analysis techniques from the latest weather prediction models, might be able to forecast the next flu season.

Weather modeling draws on current conditions and filters to make predictions. Now that we're all Googling flu-related queries when we get sick, real-time influenza infection rates are available online. Epidemiologists can feed this info into models like the ones used for weather that can sort through the chaos to predict sickness or health.

Researchers tested the flu formula against data from five actual recent flu seasons in New York City. Given online flu search information, they were able to predict the peak of the outbreak in the city nearly two months in advance. The findings are in Proceedings of the National Academy of Sciences.

Now, I would love a prediction of when I'm going to be fully recovered.
