The son said, "Father, I have just now told you 'It's a crow'." After a little while, the old father again asked his son the 3 time, "What is this?" At this time some expression of was felt in the son's tone when he said to his father. "It's a crow, a crow, a crow." A little after, the father again asked his son the 4 time, "What is this?"

A little later the father went to his room and came back with an old tattered diary, which he had maintained since his son was born. On opening a page, he asked his son to read that page. When the son read it, the following words were written in the diary: "Today my little son aged three was sitting with me on the sofa, when a crow was sitting on the window. My son asked me 23 times what it was, and I replied to him all 23 times that it was a crow. I hugged him lovingly each time he asked me the same question again and again for 23 times.

According to the Centers for Disease Control and Prevention,more than 126 million Americans who don't smoke are exposed to secondhand smoke in their homes,vehicles,workplaces,and public places.This exposure causes thousands of lung cancer and heart disease deaths among nonsmokers every year,according to the California Environmental Protection Agency. "Making the leap from the effects of secondhand smoke on humans to their effects on pets isn't a big one," says veterinarian Carolynn MacAllister of Oklahoma State University. "There have been a number of scientific papers recently that have reported the significant health threat secondhand smoke poses to pets," MacAllister said."Secondhand smoke has been associated with oral cancer and lymphoma in cats,lung and nasal cancer in dogs,as well as lung cancer in birds." Studies have also shown that dogs living in a smoking household are susceptible to cancers of the nose and sinus area,particularly if they are a long-nosed breed,because their noses have a greater surface area that is exposed to carcinogens and a greater area for them to accumulate.Dogs affected with nasal cancer normally don't survive for more than one year. "Short and medium-nosed dogs are more susceptible to lung cancer,because their shorter nasal passage aren't as effective at accumulating the inhaled secondhand smoke carcinogens," MacAllister said."This results in more carcinogens reaching the lungs." Birds are also at risk for lung cancer,as well as pneumonia,because their respiratory systems are hypersensitive to any type of air pollutant. To help prevent animals from being adversely affected by smoking,pet owners who smoke should have a designated smoking area that is separated from the home or stop smoking altogether,MacAllister said. Question: What can be suggested according to the passage? - Smokers can smoke anywhere. - Smokers can smoke at any time. - Smokers should smoke in the designated place. - Smokers must give up smoking at once.
Smokers should smoke in the designated place.

Proper table manners are likely to help you make a good impression. According to a US expert, Emily Post, "All rules of table manners are made to avoid ugliness." While Henry Hitchings of the Los Angeles Times admits that good manners can reduce social conflict, he points out that mostly their purpose is protective - they turn our natural warrior-like selves into more elegant ones. So where did table manners come from? In medieval England, a writer named Petrus Alfonsi took the lead to urge people not to speak with their mouths full. And King David I of Scotland also proposed that any of his people who learned to eat more neatly be given a tax deduction . Disappointingly, that idea never _ . It was during the Renaissance, when there were real technical developments, opinions of correct behavior changed for good. "None of these was more significant than the introduction of the table fork," wrote Hitchings. "Gradually, as forks became popular, they brought the new way of eating, making it possible, for instance, to consume berries without making one's fingers dirty." Forks were introduced to Britain in 1608 and 25 years later, the first table fork reached America. Yet while most of the essentials are the same on both sides of the Atlantic, there are a few clear differences between what's normal in the US and what holds true in the UK. For example, in the US, when food needs cutting with a knife, people generally cut a bite, then lay aside the knife and switch the fork to their right hand. Then they pick up one bite at a time. By contrast, Britons keep the fork in the left hand and don't lay the knife down. Though globalization has developed a new, simpler international standard of table manners, some people still stick with the American cut-and-switch method.The Los Angeles Times noted, "They are hanging on to a form of behavior that favors manners above efficiency." Question: What does the story mainly talk about? - The importance of proper table manners . - The development of table manners in Western countries. - Some unwritten rules of table manners in the US and UK. - Differences between American and British table manners.
The development of table manners in Western countries.
