The Centers for Disease Control and Prevention describes social distancing as "remaining out of congregate settings, avoiding mass gatherings and maintaining distance (approximately 6 feet or 2 meters) from others when possible."
疾病控制與預(yù)防中心將社交距離描述為“遠(yuǎn)離人員聚集場(chǎng)所，避免大規(guī)模聚集，并盡可能的保持與他人的距離（約6英尺或2米）。
Why? When someone coughs or sneezes, small drops of liquid spray from their nose or mouth. If you're standing too close, you can breathe in the droplets, which may contain the coronavirus if the person coughing is infected, according to the World Health Organization.
為什么？ 當(dāng)某人咳嗽或打噴嚏時(shí)，會(huì)從他們的鼻子或嘴里噴出一小滴飛沫。 根據(jù)世界衛(wèi)生組織的說(shuō)法，如果您站得太近，則可以吸入飛沫，如果咳嗽的人已經(jīng)被感染，飛沫中則可能含有冠狀病毒。
The "6 feet of distance" rule comes from studies of respiratory physiology, said Dr. William Schaffner, infectious disease expert at Vanderbilt University.
范德比爾特大學(xué)（Vanderbilt University）傳染病專家威廉·沙夫納（William Schaffner）博士說(shuō)，“ 6英尺遠(yuǎn)”的要求來(lái)自對(duì)呼吸生理學(xué)的研究。
"Without a cough or a sneeze, if we exhale, the distance 3 to 6 feet from each other is called the breathing zone. And it's in that kind of volume of air that what I exhale begins to mix with the air that's already in the room," Schaffner said. "So if you're standing within 3 to 6 feet of me, you may well inhale some of what I exhale. And of course if I have the virus, what I'm exhaling microscopically contains the virus."
“沒(méi)有咳嗽或打噴嚏，如果我們?cè)诤魵猓舜酥g的3到6英尺的距離則稱為呼吸區(qū)。而我呼出的氣體與房間中在這個(gè)距離內(nèi)的已經(jīng)存在的空氣混合，”沙夫納說(shuō)。 “因此，如果您站在我3至6英尺的范圍內(nèi)，您可能會(huì)吸入一些我呼出的東西。當(dāng)然，如果我感染了這種病毒，那么我從微觀上我呼出的就含有這種病毒。”
If you're finding it hard to estimate what exactly 6 feet looks like, we've got a list of animals, people and things you can keep in mind to help you judge the appropriate distance you should keep from other people.
如果您很難估算6英尺長(zhǎng)到底有多少，我們可以記住一系列動(dòng)物，人和事物，以幫助您判斷是否與他人保持適當(dāng)?shù)木嚯x。
Two Golden Retrievers standing nose to tail
The average Golden Retriever has a body length of 37 to 42 inches. Two of these dogs should amount to just over 72 inches, or 6 feet.
兩只金毛獵犬頭對(duì)著尾站著
一般金毛獵犬的平均體長(zhǎng)為37到42英寸之間。兩只狗的總長(zhǎng)應(yīng)該超過(guò)72英寸，也就是6英尺。
A man wearing a top hat
A man of average height stands at 5 feet 9 inches tall -- if that man wears a President Abraham Lincoln-esque top hat, he'd be just over the distance we're advised to keep from others.
一個(gè)戴禮帽的男人
一個(gè)中等身高男人的身高有5英尺9英寸--如果他戴著一頂亞伯拉罕·林肯總統(tǒng)風(fēng)格的禮帽，他身長(zhǎng)就剛好超過(guò)了我們被建議的應(yīng)與其他人保持的距離。
An average sedan
Think of the width of your car when trying to gauge an appropriate distance -- an average large sedan is a little more than 6 feet wide.
普通轎車
當(dāng)你在測(cè)量一個(gè)適當(dāng)?shù)木嚯x時(shí)，請(qǐng)考慮一下汽車的寬度--一輛普通的大型轎車的寬度略大于6英尺。
A sofa
A standard three-seat sofa can be up to 6 feet long -- which means that you and the person sitting on the other end of it probably aren't far away enough from each other.
沙發(fā)
一個(gè)標(biāo)準(zhǔn)的三人座的沙發(fā)可達(dá)6英尺長(zhǎng)--這意味著你和坐在沙發(fā)另一端的人之間的距離可能不夠遠(yuǎn)。
The length of a mattress
The lengths of full- and twin-size beds are about 6.2 feet from top to bottom.
床墊的長(zhǎng)度
全尺寸床和雙人床的長(zhǎng)度從床頭到床尾大約為6.2英尺。
Two adult cats
Cat lovers may find it easy to commit this comparison to memory: Two male adult cats, at 35 inches each from their heads to the tips of their tails, can amount to nearly 72 inches.
兩只成年貓
愛(ài)貓人士可能會(huì)很容易的記住這樣的比喻：成年雄性貓，每只從頭部到尾部各長(zhǎng)35英寸，兩只大約有72英寸。
A door
A door should be relatively easy to find when questioning whether you and your friend should move farther apart. Six feet is a little shorter than the average modern door, which runs from 78 to 80 inches.
一扇門
當(dāng)您和您的朋友對(duì)兩人是否應(yīng)該距離更遠(yuǎn)產(chǎn)生疑問(wèn)時(shí)，門應(yīng)該相對(duì)容易找到的。六英尺距離比普通的現(xiàn)代的門要短一點(diǎn)，現(xiàn)代門的長(zhǎng)度從78英寸到80英寸不等。
