Social distancing is not a new concept in the natural world，where infectious diseases are commonplace.Through specialized senses animals can detect certain diseases and change their behavior to avoid getting ill.
In 1966，while studying chimps（猩猩）in a Tanzanian national park，zoologist Jane Goodall observed a chimp named McGregor who had caught a highly infectious virus.His fellow chimps attacked him and threw him out of the troop.In one instance，McGregor approached chimps in a tree.He reached out a hand in greeting，but the others moved away without a backward glance.
"For a full two minutes，old McGregor sat motionless，staring after them，" Goodall notes in her 1971 book In the Shadow of Man. "It's really not that different to how some societies react today to such a tragedy."
Not all animals are so aggressive toward their ailing neighbors.Sometimes it's as simple as avoiding those who may infect you.
When Kiesecker，a lead scientist in America，studied American bullfrog in the late 1990s，he found that bullfrogs could not only detect a deadly smell of infection in other bullfrogs，but healthy members actively avoided those that were sick.Bullfrogs rely on chemicals signals to determine who is sick or not.
Caribbean lobsters also shun diseased members of their community，well before they become infectious.It takes about eight weeks for lobsters infected with the deadly virus Panulirus argus mininuceovirus to become dangerous to others.Normally social animals，lobsters begin keeping away from the diseased as early as four weeks after infection - once the lobsters can smell certain chemicals released by sick individuals.
"Overall，it's important to note that，unlike us，animals don't realize if they stay home，they might actually reduce the infection rate，" Kiesecker explains. "As humans，we have that abiljye.aiy.It's a big difference."

2．Ever since I graduated from high school I've worked in the factories surrounding my hometown every summer.However，making the transformation between school and full-time blue-collar work during the break never gets any easier.For a student like me who considers any class before noon to be unacceptable，getting to a factory by 6 o'clock each morning is suffering.My friends never seem to understand why I'm so relieved to be back at school or that my summer vacation has been anything but a vacation.
There are few people as self-confident as a college student who has never been out in the real world.People of my age always seem to overestimate the value of their time and knowledge.In fact，all the classes did not prepare me for my battles with the machine I ran in the plant，which would jam whenever I absent-mindedly put in a part backward or upside down.
The most stressful thing about blue-collar life is knowing your job could disappear over night.Issues like being laid off and overseas relocation had always seemed distant to me until my co-workers told me that the unit I was working in would shut down within six months and move to Mexico，where people would work for 60 cents an hour.
After working 12-hour shifts（輪班）in a factory，the other options have become only too clear. "This job pays well，but it's hell on the body，" said one co-worker. "Study hard and keep reading." she added.When I'm back at the university，skipping classes and turning in lazy re-writes seems too irresponsible after seeing what I would be doing without school.All the advice and public-service announcements about the value of an education that used to sound stale（陳腐的）now ring true.
My experiences in the factories have inspired me to make the most of my college years before I enter the real world for good.

3．The size of the British Isles often leads people to think that the languages spoken in its countries of England，Scotland，Wales and Northern Ireland are somewhat the same.At first，visitors are often surprised to find that they have difficulty in understanding the accents and dialects of certain regions.Even in England there are many different dialects.
Experts believe that for most English people，the places they come from are very important to them.Accents are clues to where people were born and where they grew up.Although some people may change the way they speak during their lifetime，most people carry at least some evidence of their accents and dialects throughout their lives.In addition to the regional accents of England，there can also be class differences among the accents.People are often able to make instant and unconscious judgments about a stranger's class by listening to his or her accent.Both the words and the pronunciation of an individual reflect his or her social position.
It is agreed that in England，the kind of English spoken by a person plays a leading role that generally is not important in North America.The importance of accents and their cultural and social relationships are well represented in films and on television in Britain.The film My Fair Lady based on George Bernard Shaw's 1912 play Pygmalion is often said to be a wonderful example of how social class and the accent were，and still are，linked in Britain.
