Do you ever have problems describing people? No worries! We’ll give you practical ways to define someone’s personality using popular film characters to help you remember! So, join us at the cinema and learn the useful character adjectives!

1. Narcissistic

Meaning: If someone is narcissistic, they think — they’re very special and more important than others.

Example: In the movie Beauty and the Beast directed by, Bill Condon, the villain Gaston is narcissistic. He admires himself and his appearance too much (he’s always looking in the mirror), and he has a lack of sympathy for others.

2. Culculating

Meaning: If someone is calculating, they make careful plans so they can get what they want in life.

Example: In the movie The Lion King directed by Rob Minkoff and Roger Allers, the baddie Scar is extremely calculating. He plots a plan to kill his brother, King Mufasa. After doing that, he blames this on his nephew, Simba.

3. Demanding

Meaning: If someone is demanding, they have very high standards and want everyone else to have these standards too.

Example: In the movie The Devil Wears Prada directed by David Frankel, the boss Miranda Presley is very demanding. She has always worked very hard, and she expects everyone else to do the same.

4. Naive

Meaning: If someone is naive, they're very innocent and have a Jack of experience in life.

Example: In the movie Elf directed by David Berenbaum, Buddy is a naive character. He’s a human who grew up in the North Pole with elves (小精灵). One day, he goes to New York City for the first time and soon realises that things are very different there.

Hayley Arceneaux, 29 will be the youngest person to go to space when she joins Inspiralion4, a private mission led and funded by Jared Isaacman, a- billionaire businessman and pilot. The mission which is scheduled to launch in October from Cape Canaveral, Florida, will be the first mission to include non-professional astronauts. For that , the crew are receiving training in areas such as the operations of the spacecraft and the rocket that will launch it, working in microgravity, emergency preparedness and mission simulations (模拟).

Arceneaux underwent treatment for bone cancer from the age of ten in St Jude Children's Hospital in Tennessee. She endured a dozen rounds of chemotherapy (化疗) and surgery to replace her left knee and thigh bone with titanium (钛) implants after her diagnosis nearly 20 years ago. She now works at the hospital as a physician's assistant.

“Honestly, I'm not nervous at all — I am just so excited," said Arcencaux, "I think having cancer made me tough." Dr. Michael Neel, who operated on Arceneaux, said, “Hayley's story will show people that not even the sky is the limit for what you can do, whether it's in medicine, commerce or life in general."

"Right now we are at step zero. The door is closed to persons with disabilities. With this pilot project, we have the ambition to open this door and make a leap, to go from zero to one,"the European Space Agency said.

My neighbor Mrs. Gargan first told me about it; " Have you seen the tree? she asked as was sitting in the backyard enjoying the October twilight.

"The one down at the corner," she explained. "It's a beautiful- all kinds of colors. You ought to see it."

I told her I would. But I soon forgot about the tree. Three days later,   I was jogging down the street, my mind swimming with worries, when a splash of bright orange caught my eye. For an instant, I thought someone’s house had caught fire. Then I remembered the tree.

As I approached it, I slowed down. There was nothing remarkable about the shape of the tree, a medium-sized maple. But Mrs. Gargan had been right about its colors. With its varied nation of color, this tree seemed to become a globe, embracing (拥抱) in its broad branches all seasons and continents: the spring and summer of the Southern hemisphere in the light-and dark greens, the autumn and winter of the Northern in the bunting yellows and bare branches.

As I wondered at this beauty, I thought of Ralph Waldo Emerson's words about the stars. If the stars appeared only once in a thousand years, he observed in Nature, imagine what an exciting event it would be. But because they're up there every night, we barely give them a look.

I felt the same way about the tree. And I had almost missed it.

Once when Emily Dickenson's father noticed a brilliant display of northern lights in the sky over Massachusetls, he lolled (鸣钟)a church bell to alert town's people. That’s what I felt like doing about the tree. I wanted to become a messenger of autumn, awakening the countryside to its wonder. I didn’t have a church bell, but as I walked home, I did ask each neighbor I passed the same simple question "Have you seen the tree?"

By four months of age, the cognitive performance of ravens in experimental tasks testing their social   intelligence and understanding of the physical world parallels that of adult great apes according to a new study.

Previous studies have demonstrated impressive cognitive abilities in ravens. These birds are capable of considering the visual perspective of others, planning for the future, and insightful problem-solving. Ravens have even been called “feathered apes”. But can they really compare with, primates when it comes to higher cognition?

To put this question to the teal, Pika and colleagues adapted a battery of experimental tests designed for primates to meet the needs or ravens. They include both physical and social cognitive skills. Physical cognitive skills include special memory, understanding relative numbers and addition, and causal reasoning, while social cognitive skills include social learning, communication, and theory of mind.

Pika and colleagues conducted their tests with eight hand-raised ravens. The researchers found that, at four months old, ravens already possessed a full-blown set of cognitive skills and did not significantly change over the time period investigated.

Comparing the performance of the ravens with chimpanzees, Pika and colleagues found that, with the exception of special memory, the ravens' performance equalled that of the great apes. The findings strengthen the idea that ravens, like great apes, have evolved general, flexible cognitive skills, rather than being highly specialized in a few ones only.

However, the researchers caution that the performance of these eight ravens may not be representative of the species as a whole. The birds in this study were tested by two highly familiar people who had hand-raised them. Such socialization factors could affect how the birds perform in cognitive tests designed and administered by humans.
