A child who has once been pleased with a tale likes, as a rule, to have it retold in almost the same words, but this should not lead parents to treat printed fairy stories as formal texts. It is always much better to tell a story than read it out of a book, and, if a parent can produce what, in the actual situation of the time and the child, is an improvement on the printed text, so much the better.

    A charge made against fairy tales is that they harm the child by frightening him or making him sad thinking. To prove the latter, one would have to show in a controlled experiment that children who have read fairy stories were more often sorry for cruelty than those who had not. As to fears, there are, I think, some cases of children being dangerously terrified by some fairy story. Often, however, this arises from the child having heard the story once. Familiarity with the story by repetition turns the pain of fear into the pleasure of a fear faced and mastered.

    There are also people who object to fairy stories on the grounds that they are not objectively true, that giants, witches, two - headed dragons, magic carpets, etc. do not exist; and that, instead of being fond of the strange side in fairy tales, the child should be taught to learn the reality by studying history. I find such people, I must say so peculiar (奇怪的, 异常的) that I do not know how to argue with them. If their cases were sound, the world should be full of mad men attempting to fly from New York to Philadelphia on a stick or covering a telephone with kisses in the belief that it was their beloved girl -friend.

    No fairy story ever declared to be a description of the real world and no clever child has ever believed that it was.

    Venom (毒液) from a local scorpion (蝎子) in Cuba is being used by Cuban scientists as an effective weapon to fight cancer. The venom, with stopping pain, anti-inflammatory (炎症) and anti-cancer properties, is the active ingredient in the medicine “Vidatox 30 CH,” which can be used to treat liver, brain, lung and other cancers. The treatment has been successfully used for more than four years in humans after being first tested in biological models. Labiofam, a Cuban laboratory, has breeding (繁殖) centers for both the Red Scorpion and Blue Scorpion. Each month, some 30,000 scorpions in Las Minas town, 270 km east of Havana are made to give the venom. After two years, the scorpions are released back into their natural habitat.

    Denyer Sanchez, a biologist from Labiofam, explained that the conditions are adjusted for reproduction, proved by the high number of breeding female scorpions. He said when the offspring (后代) becomes able to live in the environment, we release them because they do not have the necessary size yet to remove their venom, said Sanchez. Sanchez also said that there is still much to research on the exploitation process of scorpions, such as female death rate or the ability to survive of the released scorpions.

    Cuban research on the scorpion's venom began at the end of 1980s in Guantanamo province, the island's eastern tip, where a group of biologists and doctors became interested in the stories told by the peasants about the venom's benefits. However, the first discovery was made by Cuban biologist Misael Bordier. In 2001, Bordier visited Mexico's National Autonomous University (UNAM) and presented the research progress in a professional journal. Bordier died in 2005, one year before Cuba's Industrial Property Office gave Labiofam the rights to exploit the patent related to the venom.

    Body language is the quiet, secret and most powerful language of all! It speaks1 than words. According to specialists, our bodies send out more 2than we realize. In fact, non-verbal communication（非言语交际）takes up about 50%of what we really 3. And body language is particularly 4 when we attempt to communicate across cultures. Indeed, what is called body language is so 5 a part of us that it's actually often unnoticed. And misunderstandings happen as a result of it.6, different societies treat the 7 between people differently. Northern Europeans usually do not like having 8 contact（接触）even with friends, certainly not with9. People from Latin American countries, 10, touch each other quite a lot. Therefore, it's possible that in 11, it may look like a Latino（拉丁美洲人）is 12a Norwegian（挪威人）all over the room. The Latino, trying to express friendship, will keep moving 13. The Norwegian, very probably seeing this as rudeness, will keep 14 which the Latino will in return regard as 15.

    Clearly, a great deal is going on when people 16. And only a part of it is in the words themselves. And when partners are from 17 cultures, there's a strong possibility of 18 But whatever the situation, the best 19 is to obey the Golden Rule: treat others as you would like to be20.

    In the years ahead, AI will raise three big questions for bosses and governments. One is the effect on jobs. Although bosses publicly praise the broad benefits AI will bring very much, their main interest lies in cutting costs. One European bank asked a technology company to find a way of reducing the staff in its operations department from 50,000 to 500. This special report has shown that AI-enhanced tools can help reduce staff in departments such as customer service and human resources by a large amount. The McKinsey Global Institute finds that by 2030 up to 375m people, or 14% of the global workers in companies or countries, could have their jobs automated away. Bosses will need to decide whether they are prepared to offer and pay for retraining, and whether they will give time off for it. Many companies say they are all for workers developing new skills, but not at the employer's expense.

    A second important question is how to protect privacy as AI spreads. The Internet has already made it possible to track people's digital（数字的）behaviour in extremely small detail. AT will offer even better tools for businesses to monitor consumers(客户) and workers, both online and in the physical world. Consumers are sometimes happy to go along with this if it results in personalised（个性化的）service. But AI probably brings privacy violations (侵犯) that are seen as shocking and morally unacceptable. In the wrong hands, useful technology could be against fair and equal treatment. Countries with a record of the careful watching of a person place, especially by the police or army and human-rights abuses already using AI to monitor political activity. The police around the world will use AI to spot criminals, but may also look on ordinary citizens secretly, in order to discover things or find out information about them. New rules will be needed to ensure agreement on what degree of monitoring is acceptable.

    The third question is about the effect of AI on competition in business. Today many firms are competing to provide AI-enhanced tools to companies. But a technology company that achieves artificial intelligence could race ahead of competitors, put others out of business and lessen competition. This is unlikely to happen in the near future, but if it did it would be of great concern.

In order to bring down the number of accident and make drivers aware of the danger of driving much fast, many speed cameras are fixed on the roads. Most of them were placed in bright yellow boxes, so drivers can see it clearly from a distance and slow down. On other hand, some officials have the opposite ideas.They believe hiding cameras are more effective than visible ones. The reason is because drivers, not knowing the exact locations of the cameras, will drive more cautious. The police are now gathered related data to make sure which is good.
