  • The world-famous Statue of Liberty standing in New York Harbor was built in France. It was France's gift to the American people. Its designer, a Freemason, was Brother Frederic A. Bartholdi (1834-1904) who conceived its design while on a visit to America. As his ship sailed into New York, Bartholdi had a vision of a woman standing on a pedestal, holding a torch and welcoming immigrants to a new life in a free land.

  • Some people believe that the aurora makes sound that accompanies the ripples and flow of the light. If the aurora does make sound, the sound would have to be generated here on Earth by some electromagnetic effect. Any noise generated by the aurora would take a long, long time to travel all the way to Earth, and the air up by the aurora is much too thin to carry sound.

  • World wide, about 1.5 million people are killed in road accidents every year. Road accident research has pointed towards driver error in the majority of cases. In the U.S. about 42,000 traffic fatalities occur every year and about 6.5 million injuries annually at a total cost of 200 billion dollars. Almost all of "driver error" can be traced to lack of emotional intelligence behind the wheel.

  • Taking tea has been a London tradition for more than 150 years. The practice was launched by the Duchess of Bedford in 1830 when she ordered a little something to ward off pangs between lunch and dinner. By the 1840s, wafer thin slices of bread spread with chopped cucumber along with light sponge cakes and freshly brewed pots of tea were being served up with tidbits of gossip all over London.

  • Alcohol is a depressant—not a stimulant as many people think. Alcohol slows down activity in the central nervous system, including the brain. Depressants affect concentration and coordination, and slow the response time to unexpected situations. In small quantities, depressants such as alcohol cause people to become relaxed and lower their inhibitions. They feel more confident and often act in a more extroverted manner. In larger quantities, depressants can cause unconsciousness and death. Benzodiazepines, heroin and cannabis are also depressant drugs. (来源:英语论坛 http://bbs.englishcn.com)

  • There are now 6 million active divers worldwide. They engage in many different types of diving, of which wreck, cave, commercial, and military diving are just a few. The most common form of diving is sport diving, or recreational diving, which is practiced at depths of less than 130 ft (39 m). Diving beyond this limit requires advanced training. The amount of time a diver can remain underwater depends on several elements. The deeper the descent, the more rapidly the diver consumes air. In addition, some people consume air at a quicker rate than others. Several factors influence how efficiently a diver uses air, including diving experience, physical fitness, general relaxation, and a healthy lifestyle that limits tobacco and alcohol intake. Most divers can spend 45 minutes to an hour at 40 ft (12 m) below the surface.

  • Business letter is a formal document typically sent externally to those outside a company but is also sent internally to those within a company. It is estimated that close to 100 million business letters are written each workday.

  • In the year 1888, the Norwegian Fridtjof Nansen made the first crossing of Greenland, travelling from East to West on skis. The report on his expedition, Paa ski over Gronland, was published in 1890 in both Norwegian and English, and later in German. It aroused great interest in skiing in Europe and the United States, as well as creating a Norwegian national hero.

  • Lewis Carol who wrote "Alice's Adventures in Wonderland" and "Alice through the Looking Glass" lived in Christ Church college, Oxford as a student and lecturer. His real name was Charles L. Dodgeson and he became a lecturer in mathematics. Alice was the young daughter of the Dean of Christ Church and the book "Alice's Adventures in Wonderland" a Christmas gift for her.

  • Leonardo da Vinci left fewer than 30 paintings, and these aren’t even all finished.

  • Mona Lisa has no eyebrows in Leonardo da Vinci's painting because during that time, a woman was considered more beautiful if she shaved her eyebrows.

  • Leonardo became a vegetarian out of pity for animals and was even known to purchase birds at the market and set them free.

  • Power from the sun comes to the Earth as heat and light. This heat and light are the effect of the Sun's constant nuclear fusion of hydrogen nuclei. The process of fusion produces helium nuclei along with large amounts of energy. This energy is expressed as electromagnetic radiation (light is a specific frequency range of this radiation) as well as radiated temperatures of more than 6,100 degrees C. Only a small fraction of these extreme levels of energy that are released by the Sun come into contact with the Earth.
