Black people are by no means ______ white people.

On Thursday afternoon Mrs. Clarke dressed for going out, took her handbag with her money and her key in it, pulled the door behind her to lock it and went to the over 60s Club. She always went there on Thursdays. It was a nice outing for an old woman who lived alone. At six o"clock she came home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? Had someone got in? She checked the back door and the windows. All were locked or fastened, as usual. There was no sign of forced entry. Over a cup of tea she wondered whether someone might have a key that fitted her front door "a master key" perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements? On the Thursday after that she went out at her usual time, dressed as usual, but she didn"t go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait. It was just after four o"clock when the front door bell rang. Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter box being pushed open. With the kettle of boiling water in her hand, she moved quietly towards the front door. A long piece of wire appeared through the letter box, and then a hand. The wire turned and caught around the knob on the door lock. Mrs. Clarke raised the kettle and poured the water over the hand. There was a shout outside, and the skin seemed to drop off the fingers like a glove. The wire fell to the floor, the hand was pulled back, and Mrs. Clarke heard the sound of running feet.

Some economists say that South Korea, while still deep in______, feels confident in its economy to increase its reserves.

Many people think there is no need to take special care over home security. "I"m all right, I"m insured". Maybe—if you"re fully insured. Even then you can never recover the real value you place upon your possessions. But you can"t insure against the upset and unhappiness that we all feel if our homes are seriously damaged by some stranger, our windows and doors smashed, our precious possessions ruined. "It won"t happen to me". Won"t it? A home is broken into almost every minute of the day. Thefts of all kinds, including cars and property stolen, happen twice as frequently. "I"ve nothing worth stealing". You may think not. But in fact every one has something worth a thief"s attention. And we all have things of special value to us even if they"re worth little or nothing in cash terms. "I"m only a tenant here". The thief doesn"t care whether you"re a tenant or an owner-occupier. You"re just as likely to be robbed. Have a word with the owner of the house if you think extra locks and fastenings are necessary. "They"ll get in any way". Most thieves are always looking for easy jobs. They are soon discouraged by houses they can"t get into quickly and easily. So it"s worth taking care. This booklet will help you—It"s based on the practical experience of police forces throughout the country. Most of the suggestions will cost you only a few minutes extra time and thought. A few may involve some expense, but this is small compared with the loss and unhappiness you might otherwise suffer. If you are in doubt, ask for free advice from the Crime Prevention Officer at your local police station.

At the International Snow Sculpture Championships in Colorado on January 27, people will carve the white stuff into art. Planning begins months before the first snow falls. Teams submit applications and sketches of their sculptures in July. Then, a panel of judges chooses 14 teams for the championship. The rules are simple: Electric tools are not allowed. Teams carve snow with everything but the results are not entirely in the sculptors" hands. "If it is extremely sunny and warm", DeWall, the competition"s director of public relations, explained, "we will erect old sail from sail boats into the air to block the sun from melting the sculptures". If it snows, she continued, teams have to work extra hard to scrape(刮掉) the new snow off their work. The judges look for creativity, technical skill, and overall impact on the viewer. The winner does not receive any money. "There is no cash prize because the event began with the concept of global camaraderie(情谊)", DeWall explained. Instead of focusing on money, she continued, "winners revel(纵情) in the friendship, the art, and the hard work".

New technology links the world as never before. Our planet has shrunk. It"s a new "global village" where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communications equipment is greatly enhanced by foreign language skills. Deeply involved with this new technology is a breed of modem businesspeople who have a growing respect for the economic value of doing business abroad. In modem markets, success overseas often helps support domestic business efforts. Overseas assignments are becoming increasingly important to advancement within executive ranks. The executive stationed in another country no longer needs fear being "out of sight and out of mind". He or she can be sure that the overseas effort is central to the company"s plan for success, and that promotions often follow or accompany an assignment abroad, if an employee can succeed in a difficult assignment overseas, superiors will have greater confidence in his or her ability to come back in the United States where cross-cultural considerations and foreign language issues are becoming more and prevalent(普遍的). Thanks to a variety of relatively inexpensive communications devices with business applications, even small businesses in the United States are able to get into international markets. English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn"t generally required to get a job in business, but having language skills gives a candidate the edge when other qualifications appear to be equal. The employee posted abroad who speaks the country"s principal language has an opportunity to fist-forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign clients over the telephone or by fax machine is an obvious asset to the firm.

There are more differences between the United States and Japan than conflicting values during World War II. Cultural and societal differences between the two nations and its peoples shaped beliefs and perceptions and thus interactions within those societies and between them as well. The Japanese media made sure to cast the United States in a negative light during the war. Even afterward, they would distort everything from Ted Kennedy"s car accident and the death of Mary Jo Kopechne to important battles and events. During World War II, newspapers tried to give the public what they wanted for morale. Positive news was widely broadcast, but anything negative was also distorted or hidden. Sons or husbands who died during World War II were heroes, for sure, but the concept of suicide missions was unknown to the Japanese. The dropping of "warning fliers" by the United States before the atomic bomb was let go is controversial. Some feel they were fair and that the Japanese denied their existence and failed to adequately warn the people. Others think they were a part of psychological warfare, really dropped after Anola Gay flew off to Hiroshima, and merely acting as a doubtful precursor of any future attacks. The war and the role of the Japanese government caused uncertainty and hatred among the Japanese toward Americans. Any of the few white people living in Japan sometimes had their houses searched --- not by the government, but by curious neighbors. "What I never got used to was my home being searched; nothing ever stolen, just investigated frequently," said one American woman living in Japan at the time. The Japanese looked upon Americans as crude and immoral, by their standards, as a melting pot without a culture of its own. They also underestimated America"s ability to unite for a cause and develop such a powerful bomb, perhaps because of the broadcasts by the Japanese media. The United States citizens looked down upon the Japanese as well, disgusted by the brutality of medical experimentation on human subjects by the Japanese government. The treatment of POWs angered the United States as well; the notable photo of Australian Sgt. Leonard Siffleet about to be beheaded with a sword didn"t help with anti-Japanese sentiments, which probably began with the "sneak attack" on Pearl Harbor. Similarly to the actions of the Japanese media during World War II, the United States felt it necessary to dehumanize the enemy with bombs. Their refusal to accept defeat angered and put off Americans, as did Japanese propaganda. Boycotts on Japanese products popped up in America. Culture clashes continue to leave gaps between America and Japan. News of sexual slavery during WWII on the part of Japan, and anti-Japanese sentiments evident in American societal products and business, keep the nations apart.

All the people who went to the new supermarket had one great hope: to be the lucky customer who did not have to pay for his shopping. For this was what the notice just inside the entrance promised. It said, "Remember, once a week, one of our customers gets free goods. This may be your lucky day!" For several weeks Mrs. White hoped, like many of her friends, to be the lucky customer. Unlike her friends, however, she never lost heart. Her kitchen was full of things which she did not really need. Her husband tried again and again to persuade her to give it up, but she just wouldn"t listen. She dreamed of the day when the manager of the supermarket would come up to say, "Madam. this is your lucky day. Everything in your basket today is free." One Friday morning, after she had finished her shopping and had taken it to her car, she found that she had forgotten to buy some tea. She rushed back to the supermarket, got the tea and went to the desk to pay for it. As she was walking, she saw the manager of the supermarket coming up. "Madam," he said warmly, holding out his hand, "I want to congratulate you! You are our lucky customer today. Everything you"ve got in your basket is free."

In the past, degrees were very unusual in my family. I remember the day my uncle graduated. We had a huge party, and for many years my mother called him "the genius" and listened to his opinion. Today in comparison, five of my brothers and sisters have degrees, and two are studying for their masters". However, some people think that this increased access to education is devaluing degrees. People have several arguments against the need for degrees. They say that having so many graduates devalues a degree. People lose respect for the degree holder. It is also claimed that education has become a rat race. Graduates have to compete for jobs even after years of studying. Another point is that studying for such a long time leads to learners becoming inflexible. They know a lot about one narrow subject, but are unable to apply their skills. Employers prefer more flexible and adaptable workers. However, I feel strongly that this move to having more qualifications is a positive development. In the past education was only for the rich; and powerful. Now it is available to everyone, and this will have many advantages for the country and the individual. First of all, it is impossible to be overeducated. The more people are educated, the better the world will be, because people will be able to discuss and exchange ideas. A further point is that people with degrees have many more opportunities. They can take a wider variety of jobs and do what they enjoy doing, instead of being forced to take a job they dislike. Finally, a highly educated workforce is good for the economy of the country. It attracts foreign investment. In conclusion, although there are undoubtedly some problems with increased levels of education, I feel strongly that the country can only progress if all its people are educated to the maximum of their ability.

Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing(裁判) decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees. The researcher organized an experimental tournament(锦标赛) involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge. Observers noted down the referees" errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number. The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum(最佳的) distance is about 20 meters. There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second. If FIFA, football"s international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues. He also says that FIFA"s insistence that referees should retire at age 35 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.

After a 300 million yuan renovation project, Lidai Diwang Miao, or the Imperial Temple of Emperors of Successive Dynasties, was reopened to the public last weekend. Originally constructed about 470 years ago, during the reign of Emperor Jiajing of the Ming Dynasty, the temple was used by emperors of both the Ming and Qing to offer sacrifices to their ancestors. It underwent two periods of renovation in the Qing Dynasty, during the reigns of emperors Yongzheng and Qianlong. From 1929 until early 2000, it was part of Beijing No. 159 Middle School. The temple"s Jingdechongsheng Hall contains stone tablets memorializing 188 Chinese emperors. The jinzhuan bricks used to pave the floor, the same as those used in the Forbidden City, are finely textured and golden-yellow in color. According to Xi Wei, an official from the Xicheng District government present at the re-opening of the temple, jinzhuan bricks were made in Yuyao, Suzhou, specially for imperial use. The renovation was done strictly according to that carried out at the orders of Emperor Qianlong, and only those sections of the temple too damaged to repair have been replaced.

If this kind of fish becomes ______, future generations may never taste it at all.

Why does cream go bad faster than butter? Some researchers think they find the answer, and it comes down to the structure of the food, not its chemical composition—a finding that could help rid some processed foods of chemical preservatives. Cream and butter contain pretty much the same substances, so why cream should sour much faster has been a mystery. Both are emulsions—tiny globules(小球) of one liquid evenly distributed throughout another. "The difference lies in what"s in the globules and what"s in the surrounding liquid", says Brocklehurst, who led the investigation. In cream, fatty globules drift about in a sea of water. In butter, globules of a watery solution are locked away in a sea of fat. The bacteria which make the food go bad prefer to live in the watery regions of the mixture. "This means that in cream, the bacteria are free to grow throughout the mixture", he says. When the situation is reversed, the bacteria are locked away in compartments(密封仓) buried deep in the sea of fat. Trapped in this way, individual colonies cannot spread and rapidly run out of nutrients. They also slowly poison themselves with their waste products. "In butter, you get a self-limiting system which stops the bacteria growing", says Brocklehurst. The researchers are already working with food companies keen to see if their products can be made resistant to bacterial attack through alterations to the food"s structure. Brocklehurst believes it will be possible to make the emulsions used in salad cream, for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning it into a solid lump.
