Built 4,000 years ago, the three great pyramids at Giza, in the Egyptian desert remain the most colossal1 buildings ever constructed.The pyramids were built by Egyptians under the orders of the Egyptian leader, whose title was Pharaoh2. There was a sequence of Pharaohs culminating3 around 2615 B.C., with the Pharaoh Cheopswho built the biggest thing ever built, the Great Pyramid, also known as Khu?fu. Cheops built a pyramid 770 feet on one side and 481 feet tall. How ancient builders managed to build these massive structures has never been fully answered but the effort clearly required brains and brawn4.Was there engineering genius involved? Yes, there was. For example, when you're putting the block right at the top, how are you going to lug5 a block of stone that weighs several tons 480 feet up a structure? How are you going to do it, and how are you going to do it without leaving scratches6 on all the rest of the structure? And how many people does it take to drag a block weighing several tons 480 feet up into the sky? Approximately, 2.3 million blocks of stone were cut, transported and assembled to create the Great Pyramid.The Pharaohs may have set out to build magnificent tombs for themselves, but in the end they created monuments to human potential. There's a universal message in the pyramids. The pyramids belong to Egypt, but the pyramids also belong to the world. That's why we can all identify the pyramids as an early monument of human greatness.For being a man?made wonder that has survived the sands of time1, the pyramids rise to the number two spot.矗立在埃及沙漠中吉萨的三座大金字塔建于4000年前,它们一直都是有史以来最宏大的建筑。
金字塔原理英文版The Pyramid Principle English Version。
The Pyramid Principle is a powerful tool for communication and problem-solving, originally developed by Barbara Minto at McKinsey & Company. This principle provides a structured way to organize and present information, making it easier for the audience to understand and absorb the key message.At the core of the Pyramid Principle is the idea that ideas should be presented in a logical order, with the most important points at the top of the pyramid. This means starting with the conclusion or recommendation first, followed by the supporting arguments, and then the details or evidence. By structuring information in this way, the audience can quickly grasp the main message and then delve into the supporting details as needed.One of the key benefits of the Pyramid Principle is its ability to streamline communication. By starting with the main point, the presenter can immediately capture the audience's attention and ensure that the key message is not buried within a mass of information. This is particularly important in business settings, where time is often limited and decisions need to be made quickly.In addition to improving communication, the Pyramid Principle also helps with problem-solving. By organizing information in a logical and structured way, it becomes easier to identify the root cause of a problem and develop effective solutions. This can be especially valuable in complex and ambiguous situations, where clarity and precision are essential.The Pyramid Principle is not only applicable to written documents and presentations, but also to verbal communication. Whether it's a formal presentation, a team meeting, or a one-on-one discussion, the principle can be used to ensure that ideas are communicated clearly and effectively.To apply the Pyramid Principle effectively, it's important to start by identifying the key message or recommendation. This forms the apex of the pyramid and serves as the guiding light for the rest of the communication. Once the main point is established, the supporting arguments can be developed, each building on the previous one to lead to the ultimate conclusion.In conclusion, the Pyramid Principle is a valuable tool for anyone involved in communication and problem-solving. By organizing information in a logical and structured way, it enables clear and effective communication, streamlines decision-making, and enhances problem-solving capabilities. Whether in a business setting or in everyday life, mastering the Pyramid Principle can greatly improve one's ability to convey ideas and make informed decisions.。

世界未解之谜金字塔作文英语Deep within the deserts of Egypt, stand the ancient monuments that have fascinated and baffled historians, archaeologists, and the general public alike for centuries. These structures, known as the pyramids, are not just monolithic tombs for ancient Egyptian royalty, but a testament to the engineering prowess and architectural genius of a civilization gone by.The largest among them, the Great Pyramid of Giza, stands as a monumental structure, visible from miles away. Constructed over a period of more than 20 years, it is estimated to have taken the efforts of tens of thousands of workers to complete. The pyramid's design is not just aesthetically pleasing but also mathematically precise, with each of its sides being almost perfectly aligned to the cardinal directions.What makes the pyramids truly mysterious, however, is not just their scale and precision but the secrets they seem to hold within their stone walls. Despite being studied and analysed for centuries, there are still many unanswered questions surrounding the constructiontechniques, purpose, and the exact methods used to align them with the cardinal directions.One of the most intriguing mysteries is the means by which the ancient Egyptians transported the巨大石块used in the construction of the pyramids. The blocks, weighing several tons each, were quarried from far-off locations and then transported to the construction site, often over distances of hundreds of miles. The question is, how did they move these巨石without the aid of modern machinery?Another mystery is the purpose of the pyramids themselves. While it is generally accepted that they were tombs for the ancient Egyptian royalty, their exactfunction and the role they played in Egyptian religion and society remain enigmatic. Some theories suggest that they were used as observatories or temples, while others believe that they were built to house the souls of the dead kings. The alignment of the pyramids with the cardinal directions is also a subject of much speculation. How did the ancient Egyptians, without the aid of modern technology, align the pyramids to within a fraction of a degree of accuracy? Some theories suggest that they used the sun andstars as guides, while others propose that they had a sophisticated understanding of geometry and trigonometry. Despite centuries of research and numerous theories, the mysteries surrounding the pyramids remain unresolved. However, it is this mystery that continues to fascinate people and spurs them to delve deeper into the past, seeking answers to the riddles posed by these ancient monuments.The pyramids of Egypt are not just structures of stone and mortar; they are symbols of human ingenuity and the boundless curiosity that drives us to explore and understand the unknown. As we continue to unravel the secrets of the pyramids, we also gain a deeper understanding of our own history and the capabilities of the human mind.**金字塔:世界未解之谜**在埃及的沙漠深处,矗立着几世纪以来一直令历史学家、考古学家和公众着迷和困惑的古老纪念碑。
