A study conducted by the University of Leeds in the United Kingdom suggest that watching cute animals may lead to a reduction in stress and anxiety.

The study examined how watching images and videos of cute animals for 30 minutes affects blood pressure, heart rate(心率) and anxiety. In December 2019, 19 people, including 15 students, joined in the study.

"There were some kittens, there was puppies, there were baby gorillas, there were quokkas —cute creatures found in Western Australia, are often referred to as 'the world's most cheerful animals'." Dr. Andrea Utley, a professor at the University of Leeds told CNN. The study was timed during winter exams, a time when stress is at an especially high level for students, according to Utley.

 The study recorded that the average blood pressure dropped from 136/88 to 115/71, which the study pointed out is "within ideal blood pressure range." Average(平均的) heart rates were lowered to 67.4 bpm, a reduction of 6.5%. Anxiety rates also went down by 35%.

"I was quite pleasantly surprised that during the session, every single measure for every single participant dropped some — heart rate reduced, blood pressure reduced," Utley said. "When they left, they filled the questionnaire(调查问卷) in again and showed that they were feeling less worried."

When questioning the participants, the study found that most preferred video clips over still images, particularly of animals interacting with humans.

Do you have trouble trying to create the next big idea?

Sometimes the answer isn't to just force an idea out of your mind.

Instead, you might want to try sitting back, relaxing and letting your mind wander（走神）. Yes, you heard that correctly. If you are in need of a new idea, try daydreaming.

Daydreams allow your mind to run freely and even increase productivity in some cases. Daydreaming develops creativity which is why you have an ah-ha moment and sudden insight（领悟） about a situation. Daydreaming allows you to uncover thoughts and ideas you did not realize you even had and get the thoughts hidden under the surface.

Researchers from the University of California, Santa Barbara, found a connection between daydreaming and creative problem-solving. Their study includes making participants first do an "unusual-use task". They had to try to come up with as many different ways to use an object as they could.

Then, the participants choose to do one of the following four things before doing the "unusual-use task" again; complete a difficult task, complete an easy task, take a 12-minute break, or skip a 12-minute break and move right on to the task exercise again.

Surprisingly, the group that performed best was the one that completed the easy task. Many participants reported that they were daydreaming while performing the easy task. So the researchers believed that this daydreaming might have helped unlock their creativity.

But how could daydreaming help the brain come up with creative ways? The answer is something known as "unconscious thought". Even when you are not actively working to solve a problem, it is still in the back of your mind. Your brain is still thinking about the problem, but in a way that you are unaware of.

When you daydream, your mind is allowed to think in ways it normally would not. Because it is free of control, it can create completely new and out-of-the-box ideas.

Great ideas never come easily, but that does not mean you always have to work hard to get them. Feel free to do what you want and let your mind wander.

Who do you think is the greatest English writer of all time? I think that person should be William Shakespeare. His popular sayings, like "To be or not to be, that is a question", and his stories such as the tragedy(悲剧), Romance of Romeo and Juliet, are almost known in every corner of the world.

In 1594, William Shakespeare became a key playwright(剧作家) of a popular acting company in the city. Whether comedies or tragedies, Shakespeare's plays catch people's hearts with the complicated(复杂的) characters and plots(情节) that show truths about human nature.

His comedies are always full of romance, and they always have happy endings. That's why people enjoy his comedies a lot. His tragedies, however, can be very dark, Macbeth tells the story about a Scottish man who becomes the king by killing all his enemies(敌人).

Shakespeare's works have had a big influence(影响) on the English language. He was a master(大师) of words. He created about 1,700 English words, including everyday ones like "lonely", "hurry" and "critical", according to the New YorkPost.

Of course, Shakespeare wrote 400 years ago and his English was very different from that of today. His plays have been translated into many languages and are acted more often than any other playwright. There are over 400 films and TV dramas adapted(改编) from his works. Shakespeare is not for an age, but for all time.

According to a study in Nature Climate Change, the population of polar bears will be in serious drop by the year 

2080. The cause is melting(融化) sea ice. Without ice, the bears must walk on the bank which is away from their main food source. That means the animals will be in danger because of lacking food.

" There's not enough food on land to support a polar bear population." Doctor Smith, the study's lead writer said. Lacking of food induces another problem. Mother bears may not be fat enough to produce milk for their babies. Some bear populations could stop having babies, leading to a rapid drop in numbers.

Arctic(北极) sea ice usually melts in the spring and summer, and then grows in the winter. But now, the ice is taking longer to grow back. Weather reports say the Arctic is warming twice as fast as the rest of the planet. Ice here has reduced 13% every 10 years since the 1970s. The Arctic is home to about 25,000 polar bears. Scientists have known that the animals are in danger.

But the study also notes that it is still possible to slow Arctic melting. The world can reduce the burning of fossil fuels(石化燃料) and lower the greenhouse gas." Saving the polar bears is up to us, I believe that there is hope. But humans need to act quickly to turn that hope into a reality." Doctor Smith said.
