Roughly the size of a soda can, sitting on a bookshelf, a relatively harmless gadget may be turning friends away from your home. The elephant in your living room is your Internet-connected security camera, a device people are increasingly using for peace of mind in their homes. But few stop to think about the effect these devices may have on house guests. Should you tell your friends, for instance, that they’re being recorded while you all watch the big game together?“It’s certainly new territory, especially as home security cameras become easier to install, “says Lizzie Post, president of the Emily Post Institute, America’s foremost manners advisors.” I think it will be very interesting to see what etiquette(礼仪)emerges in terms of whether you tell people you have a camera or not, and whether guests have a right to ask that it be turned off, if it’s not a security issue.”Post wants to make clear that she’s not talking about legal rights, but rather personal preferences. She also wants to explain that there are no right or wrong answers regarding manners on this front yet, because the technology is just now becoming mainstream. Besides, the Emily Post Institute doesn’t dictate manners.When it comes to security cameras, Post says it’s a host’s responsibility to make sure guests feel comfortable within their home. “I’m always a fan of being open and honest.” For instance, if the host casually acknowledges that there is a camera in the room by telling a story about it, which may be enough to provide an opening for a guest to say if they are uncomfortable.However, if a contractor is working in your home, you don’t need to tell them that there are cameras watching. Then again, the air of accountability that the camera generates can also work in contractors’ favor. “If anything does go wrong while they’re in the house, they don’t want to be blamed for it,” she says. “In fact, the camera could be the thing that proves that they didn’t steal the $20, or knock the vase off the table.”1.For what reason may your friends feel reluctant to visit your home?A.The security camera installed may intrude into their privacy.B.They don’t want their photos to be circulated on the Internet.C.The security camera may turn out to be harmful to their health.D.They may not be willing to interact with your family members.2.What does Lizzie Post say is new territory?A.The effect of manners advice on the public.B.Cost of applying new technologies at home.C.The increasing use of home security devices.D.Etiquette around home security cameras.3.What is Lizzie Post mainly discussing with regard to the use of home security cameras?A.Legal rights.B.Moral issues.C.Likes and dislikes of individuals.D.The possible impact on manners.4.What is a host’s responsibility regarding security cameras, according to Lizzie Post?A.Making their guests feel at ease.B.Indicating where they are.C.Turning them off in time.D.Ensuring their guests’ privacy.5.In what way can the home security camera benefit visitors to your home?A.It can satisfy their curiosity.B.It can prove their innocence.C.It can help them learn new technology.D.It can make their visit more enjoyable.

For thousands of years we Chinese have always regarded chopsticks the simplest possible and the most efficient tool for transporting bite-sized morsels of food form. a bowl to the mouth. As early as in the Zhou Dynasty， chopsticks were used for picking up meat and vegetables， while hands were used for rice.// Chopsticks， which are roughly uniform. in size throughout China， can be made of a variety of materials， including bamboo， wood， lacquer， jade， ivory， plastic， aluminum， silver and gold. Special long bamboo chopsticks are generally used in the kitchen.// The way we Chinese handle our chopsticks is quite artistic and varied from person to person like one's signature. An average Chinese can very easily pick up a single tiny grain of rice， or a tiny piece of peas， or a slippery button mushroom or sea cucumber.// When using chopsticks， one should place both sticks between the thumb and forefinger. The point is to keep one stick still and move the other so as to make them work like pincers.

There are an extremely large number of ants worldwide. Each individual （个体的） ant hardly weigh anything， but put together they weigh roughly the same as all of mankind． They also live nearly everywhere， except on frozen mountain tops and around the poles. For animals their size， ants have been astonishingly successful， largely due to their wonderful social behavior.

In colonies （群体） that range in size from a few hundred to tens of millions， they organize their lives with a clear division of labor. Even more amazing is how they achieve this level of organization. Where we use sound and sight to communicate， ants depend primarily on pheromone （外激素）， chemicals sent out by individuals and smelled or tasted by fellow members of their colony. When an ant finds food， it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying， it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit.

In fact， when it comes to the art of war， ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves， attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy.

Behaving in this selfless and devoted manner， these little creatures have survived on Earth， for more than 140 million years， far longer than dinosaurs. Because they think as one， they have a collective （集体的） intelligence greater than you would expect from its individual parts.

precedented change in the nation's economy would bring social chaos. In the years following 1820 after several decades of relative stability the economy entered a period of sustained and extremely rapid growth that continued to the end of the nineteenth century. Accompanying that growth was a structural change that featured increasing economic diversification and a gradual shift in the nation's labor force from agriculture to manufacturing and other nonagricultural pursuits.

Although the birth rate continued to decline from its high level of the eighteenth and early nineteenth centuries the population roughly doubled every generation during the rest of the nineteenth century. As the population grew, its make up also changed. Massive waves of immigration brought new ethnic groups into the country. Geographic and social mobility — downward as well as upward — touched almost everyone. Local studies indicate that nearly three quarters of the population in the North and South, in the emerging cities — the Northeast and in the restless rural counties of the West — changed their residence each decade. As a consequence, historian David Donald has written, "Social atomization affected every segment of society," and it seemed to many people that "all the recognized values of orderly civilization were gradually being eroded.

Rapid industrialization and increased geographic mobility in the nineteenth century had special implications for women because these changes tended to magnify social distinctions. As the roles of men and women played in society became more rigidly defined, so did the roles they played in the home. In the context of extreme competitiveness and dizzying social change, the household lost many of its earlier functions and the home came to serve as a haven of tranquility and order. As the size of families decreased, the roles of husband and wife became more clearly differentiated than ever before. In the middle class especially, men participated in the productive economy while women ruled the home and served as the custodians of civility and culture. The intimacy of marriage that was common in earlier periods was rent, and a gulf that at times seemed unbridgeable was created between husbands and wives.
