Detective Keeling took his client—a good­looking lady into the back yard of the store together. The lady opened a door in the wall and they entered the small room behind the store. They crossed the room to a locked door.

    Mr. Keeling took some special keys from his pocket. Moments later, one of the keys unlocked the door. The lady went into the store. She said she would hide under the table to keep watch on her husband. Mr. Keeling did not follow her.

    The detective went quickly to the policeman's house. Then the two men hurried to the jewellery store. They looked through the window. The policeman was surprised. He spoke to Mr. Keeling, “I don't understand. You told me, ‘Robbins took a young woman to a restaurant.' Where is she?”

    “There she is!” said Mr. Keeling. He pointed through the window.

    “Do you know the lady with Robbins?” asked the policeman.

    “That's his secret friend,” said Mr. Keeling.

    “No! You're wrong! That's Robbins' wife,” said the policeman. “I've known her for fifteen years.”

    “What?” the detective shouted. His face became pale. “Who is under the table in the store?” He started to kick the door of the jewellery store. Mr. Robbins came to the door and opened it. The policeman and the detective ran into the store.

    “Look under that table!” shouted the detective. “Be quick!”

    The policeman lifted the cloth and put his arm under the table. He pulled out a black dress, a black veil and a woman's wig(假发).

    “Is this young lady your wife?” Mr. Keeling asked the jeweller. He pointed at the woman.

    “Yes! She is my wife!” said Mr. Robbins angrily. “Why did you kick my door? Why are those clothes under my table?”

    “Please check all the jewellery in your store, Mr. Robbins,” the policeman said. “Is anything missing?”

    Some diamond rings and some expensive necklaces were missing. The missing jewellery was worth $800. Later that night, Mr. Keeling was sitting in his office. He was looking through a big book of photographs. They were photographs of criminals. The policeman had brought the book to the detective's office. Suddenly, Mr. Keeling stopped turning the pages. He looked at a picture of a handsome young man with a familiar face.

    The next morning, Mr. Keeling paid the jeweller $800, then closed his office.

    You've probably heard the term “you are what you eat.” If you decide to eat sugary foods that are heavy with fats then expect to feel lazy and have no energy. But if you decide to eat fruits, vegetables and make other healthy eating decisions you'll find that you're full of energy.

Never stop learning

Challenge yourself constantly—whether it is puzzles, reading, cooking or other tasks that will keep your mind working. If your mind is always learning new things and active, you'll realize that it's much easier for you to learn new things and to function.{#blank#}2{#/blank#}

    Nowadays wind is useful. Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

    For many centuries, people used windmills to grind wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s, when electricity was available to people in almost all areas of the United States, windmills were rarely used.

    During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

    An extremely enthusiastic truth seeker who runs the YouTube channel Bright Insight claims（声称）to have found the mysterious city of Atlantis and insists that its true location has been hiding in plain sight for thousands of years.

    In a video, YouTube blogger Jimmy Bright argues that the Richat Structure, a geologic dome（穹状物）in northwest Sahara also referred to as the Eye of the Sahara, is the most likely location of Atlantis.

    He mentioned measurements from the famous Dialogues of Plato, which gave birth to the mystery. The Greek philosopher（哲学家）claimed that Atlantis was a long-gone kingdom, which stretched into Europe as far as Italy and into Africa as far as Egypt thousands of years ago. The giant island was said to be wiped off the face of the planet by a natural disaster “in a single day and night of misfortune”.

    At first sight, this has nothing to do with the land-based Richat Structure, but Jimmy claims that the so-called Younger Dryas theory could be a possible explanation. According to it, a massive change in global temperatures caused unexpected climate change and sea level to rise.

    In what can be viewed as another proof to the Sahara theory, the diameter（直径）of the Richat Structure's outer circle is 23.5 km according to Google Map's measurements, which matches those mentioned by Plato — 127 stadia, which is roughly 23.5 km in today's terms.

    Another thing that helps solve the mystery is a theory that the Eye of the Sahara closely matches the description from Plato's dialogues. The ancient philosopher wrote that the main city of Atlantis consisted of circles of water and land, which, Jimmy said, looks very similar to the circular form of the Richat Structure.

    Although the majority of researchers believe that Plato's story was nothing but a moral story used to describe a failed idea of seeking power and searching for fortune, it has raised quite a few theories, Since the Middle Ages, explorers have been pointing fingers at different places around the world, including the Atlantic Ocean and the Mediterranean Sea, with the most amazing theories linking the location of Atlantis to the Antarctic and the North Sea.

    Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the "on/off" button on the TV. But some buttons are actually fake, like the "close" button on a lift.

    Many people are in the habit of pressing the "close" button because they don't have the patience to wait for the lift doors to shut. But lifts "close" buttons are a complete scam, at least in the US-the doors will not close any faster no matter how hard you press.

    It started in the 199os when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

    But to normal lift riders, the buttons aren't completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control." Perceived（能够感知的）control is very important. It reduces stress and increases well-being," Ellen J. Langer, a psychology professor, said," Having a lack of control is associated with depression."

    Experts have revealed that a lot of buttons that don't do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats（温度调节器）because people tend to feel better when they think they can control the temperature in their workspace.

    But psychologists found it interesting that even when people are aware of these little" white lies", they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

   "That habit is here to stay," John Kounios, a psychology professor, said," Even though I have real doubts about the traffic light buttons, I always press them. After all, I've got nothing else to do while waiting.  So why not press the button in the hope that this one will work?"
