In many businesses, computers have largely replaced paperwork, because they are fast, and do not make mistakes. And they are honest. Many banks say that their business is “untouched by human hands” and therefore safe. But they have no thought that the growing number of computer crimes (犯罪) show they can be used to steal.

    Computer criminals (罪犯) don't use guns. And even if they are caught, it is hard to punish them because there is often no proof. A computer cannot remember who used it. It simply does what it is told. The head teller(出纳主管) at a New York City bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this because he moved the money from one account (账户) to another. Each time a customer whose money he had stolen questioned the balance in his account, the teller said it was a computer mistake, then replaced the missing money from someone else's account. This man was caught at last.

    Some workers use the computer's power to punish their bosses they consider unfair. Recently, a large company fired its computer record assistant for reasons that were connected with her personal life rather than her job. She was given thirty days notice. In those thirty days, she stole all the company's computerized records.

    Most computer criminals have been common workers. Now police wonder if this is “the tip of iceberg”. As one official says, “I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing—the ones who really know a computer works.”

    Global warming threatens to hold back human progress, and make unachievable all UN targets to reduce poverty, according to some of the world's leading international and development groups.

    In a report published today, Oxfam, Greenpeace and other groups say rich governments must immediately address climate change to avoid even “unbearable levels” of worldwide poverty.

     “Food production, water supplies, public health and people's livelihoods are already being damaged and weakened,” the report says. “There is no approach possible. The world must meet its commitments to achieve poverty reduction and also deal with climate change, which are closely linked.”

    The report, which draws on UN predictions of the effects of climate change in poor countries over the next 50 years, says poor countries will experience more flooding, declining food production, more disease and the extinction of entire eco-systems on which many of the world's poorest people depend.

     “Climate change needs to be addressed now. The poor will bear the great consequence of it. The frontline experience of many of us working in international development indicates that communities are having to fight more extreme weather conditions.”

    Climate change will cause great damage to agriculture and water supplies and will increase diseases. “By 2025 the number of the world's population living in countries of significant water stress will almost double, to 6 billion people. Tropical (热带的) and sub-tropical areas will be hardest hit — those countries already suffering from food shortage”.

    Poor countries mostly do not need hi-tech solutions, but would most benefit from education, research and being shown how to farm better. The report says unchecked global warming, more than wars or political upheaval (政变), will displace millions of people and unsettle many countries.

    Throughout much of human history, man has been the measure of many, if not all, things. Lengths were divided up into feet and smaller units from the human hand. Other measures were equally characteristic. Mediterranean traders for centuries used the weight of grains of wheat to define (定义) their units of mass. The Romans used libra, forerunner of the pound, by referring to the weight of a carob (角豆树) seed.

    The sizes of similarly named units could also differ. The king's foot, used in France for nearly 1, 000 years after its introduction by Charlemagne in around 790 AD, was, at 32.5cm, around a centimeter shorter than the Belgic foot, used in England until 1300.Greek, Egyptian and Babylonian versions of water in a fixed container varied from one another by a few kilos, Nor was there agreement on such things within countries. In France, where there was no unified (统一的) measurement system at the national level, the situation was particularly terrible. The lieue (former measure of distance), for example, varied from just over 3 km in the north to nearly 6 km in the south.

    Although John Wilkins, an Englishman, first put forward a decimal system (十进制) of measurement in 1668, it was the French who in 1799 made it law. The Système International d'Unités (SI, or the metric system, as it is better known) developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States. Now the International Bureau of Weights and Measures in Paris is set to give the metric system its biggest shake-up yet.

    At a meeting in Versailles, France, on November 16th, 2018, the world's measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常数).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20^th 2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.

    Many animal and plant species have become extinct and many more are in critical danger. Finding ways to protect the earth's wildlife and conserve the natural world they inhabit (居住) is now more important than ever.

    Dodo

    The Dodo is a classic example of how human caused damage to the earth's biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island's trees and lived unthreatened until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and the last one was killed in 1681.

    Rhinos

    The Rhino (犀牛) horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most Rhinos now live in protected natural parks and reserves (保护区). Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers (偷猎者).

    The Giant Panda

    The future of the World Wildlife Fund's symbol is far from certain. As few as 1, 000 remain in the wild. The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison. However, the panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose (造成) one of the most serious threats to the animals continued existence.

    Whales

    The International Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that one-third the world's oceans have been declared whale sanctuaries (保护区), 7 out of 13 whale species remain endangered. Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.

    Tigers

    The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5, 000 and 7, 000 and the Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tigers' bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.

    Scientists, psychologists and English academics at Liverpool University have found that reading the works of the classical writers like Shakespeare and Wordsworth has a great effect on the mind, catches the reader's attention and triggers moments of self-examination.

    Using a special machine, they monitored the brain activity of 30 volunteers as they read works by William Shakespeare, William Wordsworth, T.S. Eliot and others.

    In the first part of the research, the brain activity of 30 volunteers was monitored as they read passages from Shakespeare's plays, including King Lear, Othello, Coriolanus and Macbeth, and again as they read the text rewritten in a simpler form or modern language.

    While reading the common texts, normal levels of electrical activity were shown in their brains. When they read the works of Shakespeare, however, the levels of activity jumped because of his use of words which were unfamiliar to them. The result of the test showed that the more challenging passages cause a greater degree of electrical activity in the brain than the common ones.

    Scientists went on to study the brain activity as it responded to each word and recorded how it lit up as the readers came across unusual words, surprising phrases or difficult sentences in the classical works. As a result, this lightening up process of the mind lasted longer than that when volunteers read common texts, encouraging further reading.

    The research also found that reading poetry especially increases activity in the right hemisphere (半 球) of the brain, an area connected with" autobiographical memory", driving the readers to think carefully about their own experiences based on what they have read. The academics said this meant the classical works of literature are more useful than self-help books.

    Philip Davis, an English professor who has worked on the study in the university's magnetic resonance center, announced this week:" Classical literature acts like a rocket-booster to the brain, which provides extra power for the brain. You may never imagine how powerful it is. The research shows such kind of literature can create new thoughts and connections in the young and the old."

Soccer is played by millions of people all over the world, but there have only been few players who were truly great. How did these players get that way—was it through training and practice, or are great players "born, not made"?

First, these players came from places that have had famous stars in the past—players that a young boy can look up to and try to imitate (模仿). In the history of soccer, only seven countries have ever won the World Cup. There has never been a great national team—or a really great player—from North America or from Asia.

Second, these players have all had years of practice in the game. Pele, who is often named as the greatest soccer of all time, was the son of a soccer player. He began to play soccer with his father when he was only three. Most players begin playing the game at the age of three or four.

Finally, many great players come from the same kind of neighbourhood—a poor, crowded area where a boy's dream is not to be a doctor, lawyer, or businessman, but to become a rich, famous athlete or entertainer (艺人). For example, Liverpool, which produced the Beatles, had one of the best English soccer teams in recent years. Pele practiced in the street with a "ball" made of rags (破布). And George Best learned the tricks that made him famous by bouncing the ball off a wall (对着墙壁踢球) in the slums (贫民窟) of Belfast.

All great players have a lot in common, but that doesn't explain why they are great. Hundreds of boys played in those Brazilian streets, but only one became Pele. The greatest players are born with some unique quality that sets them apart from all the others.
