Shadow puppetry (皮影戏), also called shadow play, got (it) start thousands of years ago in China and India. This unique form of storytelling is the (old) type of puppetry in the world .

Shadow puppets are figures that (place) between a light and a screen. Moving them creates the illusion (假象) of moving pictures on the screen.experienced puppeteer can make figures appear to walk, talk, fight and dance.

China, India, Indonesia and Turkey have been very important in the (develop) of this art form over time. The types of stories (tell) with shadow puppetry vary from country to country.

For example, in China, shadow plays are usually based on Chinese folk tales.

Traditional Chinese shadow puppets are made out of animal skin. Today, you might see different kinds of shadow puppets, many ofalso contain paper, plastic, wood or cloth. There's really no end to how creative puppeteers can be when (make) their puppets.

Shadow puppets are usually constructed from separate (piece) that are then put together with strings or wires. The strings or wires are usually attachedlong sticks that the puppeteer will use to control the movement of the puppet.

The aim of this2 is to create dolls that would have the same characteristics as their owners with disabilities or3 conditions. Amy created such dolls to make the children feel needed and4. To do so, Amy goes out of her way to make each doll5 the child. Each doll is unique,6 they still have one thing in common — all dolls wear a smile. Not only beautiful, the dolls make a7 in the lives of hundreds of children.

"Typically, parents pay for the dolls — about $ 100 with shipping per doll. When they can't afford it, I'll find a way to8 it myself. Whatever it costs, whatever I have to do, I'm going to get a doll in the9 of these children. "

A Doll Like Me has provided over 300 dolls so far which have been10 to children all around the world. Amy's11 goal is to turn her small business into an official non-profit organization where every child in need could get their one-of-a-kind doll12.

And many people are responding13 to her mission, as she has already reached $ 38,000 out of $50, 000 goal on GoFund. me. Amy is already cooperating with a children's14 to make it easier to identify kids whose well-being could be15 by a stuffed toy which looks just like them!

Trying new things is good for our brain. It helps us think more creatively and enhances confidence. It also helps us destress in that a new experience can help break harmful or negative routines. We will consider things from new and different perspectives.

It is obvious that trying new things is good for our mental health. Participating in new physical activities can improve our physical fitness, boost our energy levels, and enhance our overall health. For example, trying a new sport or exercise routine can increase our flexibility and strength. Having new experiences can also have a positive impact on our social lives. . When we step out of our comfort zones and engage in new activities, we· meet people with different backgrounds and perspectives, which can broaden our horizons and enrich our lives. Building new relationships can provide us with a sense of belonging.

Still, it can be scary to break routine and try something totally different. Start small by breaking a goal into smaller steps. And be very specific about the goal. For example, instead of aiming to work on arm strength, make a goal of doing twenty arm curls (弯曲) a day. In addition, be realistic and make sure the goal î s practicable in terms of finances and free time.

While it is easy to get caught up in the daily tiring activities of life, always keep in mind that doing something new can be the best thing we can do for ourselves. So we'd better make the wise choice.

A. However, it is also good for our body.

B. It can help us expand our social connections.

C. Luckily there are practical tips to make a change.

D. New experiences are critical for overcoming fears.

E. Doing something new also promotes flexible thinking.

F. Every new experience contributes to our personal growth.

G. And yet, new experiences are vital for our overall wellbeing.

But a question remains in science: Are we the only species who do this? As one of out closest relatives, chimpanzees have long been studied for signs of this. So far, research has provided mixed results on the question.

Some studies show that chimps cooperatively hunt, share food and comfort each other. But one study came to a very different conclusion. The study used a controlled lab experiment where chimpanzees in enclosures were given two options: push a button to give food to themselves or push the button to give food to themselves AND a partner chimp. If they chose the latter, it was seen as a prosocial behavior. But the result is that chimps showed no special preferences for feeding themselves and a friend over feeding just themselves. Another study conducted by DeTroy, however, discovered a totally different result.

Compared to previous controlled lab-based experiments, the setup for DeTroy's research was very naturalistic. "We installed a button and a fountain into the chimpanzees' outer enclosures. When an individual pushes the button, it releases juice from the fountain. However, since the button and fountain are approximately five meters apart, the individual pushing cannot directly drink from the fountain. And if any other chimpanzees are at the fountain when the button is pushed, they, and not the pusher, will be able to drink the juice.

In this experiment, chimpanzees showed a willingness to act in the interest of others, with individual chimpanzees prepared to push the button without benefiting themselves.

"It is really fascinating to see that many of the chimpanzees were willing to prosocially provide valuable resources to the group members even if they couldn't benefit themselves from their behavior." said DeTroy.

Further research may reveal what lies behind their prosocial motivation. But for now, it's safe to assume that chimpanzees are not simply aping human behavior.

The body's circadian clock-the biological clock that organizes bodily activities over a 24-hour period-contributes to normal variations in blood pressure and heart function over the course of the day. In most healthy humans, blood pressure dips (下降) at night. People who do not experience this temporary drop, called "non-dippers", are more likely to develop heart disease. The circadian clock is made up of four main proteins (encoded by "clock genes") that regulate close to half of all genes in the body, including those important for blood pressure regulation.

Previous research has shown that male mice that are missing one of the four clock genes (PER1) become non-dippers and have a higher risk for heart and kidney disease. A research team studied the circadian response and blood pressure of female mice that lack PER1 and compared them with a healthy female control group. On both low-and high-salt diets, both groups "retained an apparent circadian rhythm" of blood pressure, the researchers explained. Unlike the male mice in previous research, the females without PER1 showed normal dips in blood pressure overnight.

These results suggest that the lack of PER1 acts differently in males and females. The findings are consistent with research showing that women are less likely to be non-dippers than men of the same age. "This study represents an important step in understanding sex differences in the regulation of cardiovascular (心血管) function by the circadian clock," the researchers wrote.

The possibility of time travel is indeed attractive. Stories exploring the subject have been around for hundreds of years. Perhaps the best-known example is science fiction novel The Time Machine, written by H. G. Wells and published in 1895. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term "time machine", coined by Wells, is now universally referred to a vehicle transporting people into the far future.

But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called "wormholes", which could be used as shortcuts to other periods. Einstein's theory of relativity allows time travel in extreme conditions. And Stephen Hawking says you could travel into the future with a really fast spaceship, going at nearly the speed of light. Though building such a spaceship wouldn't of course be simple.

Even if you could travel into the past, there is something called the "grandfather paradox". It asks what would happen if a time traveler were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born. If the time traveler wasn't born, how would he travel back in time?

And would you really like to visit the future? In H. G. Wells' book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30 million years into the future where the only living thing is a black object with tentacles.

If that's what's in store, maybe we are better just living in the present day after all.

Here's the thing — I do not have a cat. And this was not the first time this particular cat had demanded my attention.

I immediately calmed down and realized my error — I had left a window open. I approached to entertain my house-guest by giving her some treats and a scratch under her collar (颈圈).

Like so many others, I shifted from working in an office to working from home. Living alone can be isolating at the best of times. It was around the one-month mark of the lockdown when I heard a meow outside my window. Sitting outside on the grass was a long-haired, golden-colored cat. I opened the window, and this beautiful cat jumped into my home. Her short visit brightened my day.

A few days later, I heard a familiar meow. I saw a name tag on her collar: Mika. On this second visit, I also noticed Mika was cross-eyed, which only made her more lovely.

Over the next few weeks, Mika would stop by occasionally. Sometimes, she only stayed for a few minutes; other times, she would wander around my apartment much longer. Each visit brightened me. Mika even helped me connect with some new neighbors, who asked if Mika was my cat. Apparently, Mika visited them as well.

While the lockdown has been awful, I suspect I might not have ever met Mika if it had not happened. But perhaps she came by at this time because she sensed a need for connection on my part.

While dogs are said to be man's best friend, a good cat can be everyone's best friend.

Visit an "abandoned" Tube station underworld and discover what secrets are hidden beneath our busy streets in our new Hidden London exhibition at London Transport Museum!

Hidden London: the Exhibition takes you on a journey of some of London's most secret spaces in the world's oldest underground system. These "forgotten" parts of the Tube network have incredible stories to tell about Britain's wartime past.

You can enjoy the largest number of rare photos and objects from disused stations that have been brought together in one location.

Discover stories about how Churchill took shelter at the height of the Blitz deep underground at Down Street station. See how shelterers lived down at Clapham South station, where they slept and how they kept entertained.

You can also explore other locations that we have recreated in our Global Gallery, including the historic abandoned ticket hall at Aldwych station with an original 1930s ticket office.

The exhibition uncovers why these "lost" parts of the underground network exist. Changes in population, economic priorities and political pressures have all led to spaces being abandoned. But they rarely stay that way. While some sections of the Tube system lie "forgotten", many have been repurposed for new activities and are used for special Hidden London tours, growing salad leaves, and for filming locations, including Charing Cross, which featured in Skyfall (2012).
