From visiting museums to watching Changing the Guard, there are some amazing experiences for you to get while in London. Here we pick some of the best free activities in London.

    Changing the Guard

    For a display of British ceremony, watch Changing the Guard outside Buckingham Palace. This is where one member of Queen's Guards exchanges duty with the old guard. Both guards are dressed in traditional red uniform and bearskin hats, and the handover is accompanied by a Guards band. Guard Mounting takes place at 11:30 am. It is held daily from May to July, and on alternate(间隔的)dates throughout the rest of the year.

    Sir John Soane's Museum

    Sir John Soane was an architect. During his lifetime he collected some valuable antiquities(古董) from all four corners of the globe. They are now on display in Sir John Soane's Museum which gives a real insight into the life of this outstanding Victorian gentleman.

    Geffrye Museum

    A very unique experience, the Geffrye Museum, located in 18th century almshouses(救济院),gives a fascinating insight into the lives of the British middle classes from the 1600s to the present day. Explore a series of room sets, complete with furnishing and textiles(纺织品)from each period.

    Hogarth's House

    In one of the world's most forbidding environments, Polar bears spend !heir summers roaming (漫步) the Arctic on large pieces of floating ice. They drift(漂移) for hundreds of miles, finding mates, hunting for seals , and fatting themselves up for the winter. Without the floating ice , the world's largest bears could not survive Yet at this moment , the polar bears' Arctic habitat (栖息地) is melting away under it because of global warming.

    Over the past three decades, more than a million square miles of floating ice has disappeared Scientists predict that, if the current rate of global warming continues, most, if not all, of the bears' floating ice will be gone by 2100. As a result, the world's polar bears could face global dying out by the end of this century.

    Already, the ice on the southern edge of the polar bears' habitat is melting about three weeks earlier than in the past. The loss of those key weeks leaves the bears less time to hunt, eat and store up fat. Once the ice melts, the bears must fast for up to eight months on land until the floating ice returns. As a result of early melting, there has been a 14 percent decline in the Hudson Bay polar bear population over the past ten years- a fall clearly caused by global warming.

    Besides, a growing number of polar bears may be drowning (溺水) as they are forced to swim more often, and for longer distances, looking for ice sheets(冰原). According to a report by the US Mincrals Management Service, researchers observed four dead polar bears floating 60miles off Alaska in September of2006 and said it was likely that many other bears swimming far off shore also drowned. Scientists have concluded that the worldwide population of about 20,000polar bears is likely to become smaller by more than 30 percent in the next 35 to 50 years alone.

    Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning experiences increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables (乘法口诀表) are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

    The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.

    Why does night fall but never break and day break but never fall？Why are people who ride motorcycles called bikers and people who ride bikes called cyclists？In what other language do people drive in a parkway and park in a driveway？In what other language do they call the third hand on the clock the second hand？

    Let's face it: English is a crazy language. There is no egg in an eggplant, neither pine nor apple in a pineapple and no ham in a hamburger. Sweet-meats are candy， while sweetbreads, which aren't sweet, are meat.

    We take English for granted. But when we explore its paradoxes(悖论), we find that quicksand can work slowly, boxing rings are square, public bathrooms have no baths in them.

    And why is it that a writer writes, but fingers don't fing, grocers don't groce, and hammers don't ham？If the plural of tooth is teeth, shouldn't the plural of booth be beeth? One goose, two geese - so one moose, two meese?

    How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can overlook and oversee be opposites, while quite a lot and quite a few are alike? How can the weather be hot as hell one day and cold as hell the next？

    English was invented by people, not computers, and it shows the creativity of human beings. That's why, when stars are out, they are visible; but when the lights are out, they are invisible. And why, when I wind up my watch, I start it; but when I wind up this essay, I end it.

Linda Brown, a real estate agent, believes that when it comes to solving homelessness, it takes a village. She spent nine years supporting homeless people in Springfield, Missouri, through a charitable organization called The Gathering Tree, which welcomed people a few times each week during daylight hours, providing a safe and welcoming place for them to take showers, socialize, or simply rest. But they had to close their doors for the night. "One cold winter night, I watched as my friends walked off into the darkness to a wet, cold camp, while we went home to a warm bed," Linda said, "I realized I had to do something."

She had an idea to create a village of tiny houses to make sure no one slept outside on her watch! Linda started fundraising. She began by appealing to her fellow estate agents in the area before branching out into local businesses.

Using these donations, Linda purchased a nearby abandoned area that already had the infrastructure in place. By February 2019, they'd built 31 tiny homes for their Eden Village and found residents for each one. All the residents must be good neighbors in order to stay in the village, and they certainly are! Linda was happy when she learned that the village actually increased local property values rather than lowering them as some people had feared.

Linda hasn't stopped working since Eden Village began. A second village opened in the fall of 2020, and there's a third location in the works as well! She hopes to have five villages across Springfield within the next five years, helping more than 200 homeless people get off the streets and into a new life.

To this day, Linda firmly believes that there are a million reasons someone can become homeless, but each of them can be solved with love and community involvement.
