How To Improve Your Studies Scientifically

Our brain can potentially memorize 2.5 petabytes (千亿兆) of information, which is roughly equal to three million hours of YouTube videos.

*Find your style. 

While listening to the history teacher, Tom draw a picture, and Jane finishes one kilo of nuts. Some study with friends, and some like siting in silence among a million books. Everybody is different. 

*

Sleep and dreams are very important to processing and storing new information. A Harvard study showed that students who had a goodnight sleep remembered their study materials 35% better than those who had poor sleep. 

*Hard start first. 

Once you are done with the hard thing, you will feel better for the rest of the day, and probably more motivated to get other things done. In this way, you will find yourself doing things more effectively. 

*Take fun seriously. 

Learning motivation is like hunger. You cannot force yourself to be motivated. If you can't recall things clearly at some moment, don't worry. Take a break, and do something funny instead. 

A．Take a good rest.
B．Good night sleep.
C．Physical exercise, regular relaxation in mind and good conversations apparently grow your brain.
D．In order to use your brain a little more effectively when you learn, here are some tips.
E．Do the things that are difficult first, because you have the strongest will power in the morning.
F．Some enjoy watching videos over reading books, and some are fond of listening to music while studying.
G．Modern learning science believes that positive emotions are very important for increasing your learning potential.

People who frequently eat fruit are more likely to report greater positive mental health and are less likely to report symptoms of depression than those who do not, according to new research from the College of Health and Life Sciences, Aston University. The team also found that people who eat savoury （咸味的） snacks such as crisps （薯片）, which are low in nutrients （营养）,  are more likely to report greater levels of anxiety. 

Published in the British Journal of Nutrition, the study surveyed 428 adults from across the UK and looked at the relationship between their consumption of fruit, vegetables, sweet and savoury snacks, and their psychological（心理的） health. The research found that both nutrient-rich fruit and nutrient-poor savoury snacks appeared to be linked to psychological health. They also found that there was no direct association between eating vegetables and psychological health. Based on the survey, the more often people ate fruit, the lower they scored for depression and the higher for mental health, independent of the overall quantity of fruit intake. By contrast, there was no link between these everyday memory lapses（差错）and fruit and vegetables intake or sweet snacks, suggesting a unique relationship between these nutrient-poor savoury snacks, everyday mental lapses,  and psychological health. 

Lead author, PhD student Nicola-Jayne Tuck commented, "Very little is known about how diet may affect mental health, and while we did not directly examine causality here, our findings could suggest that frequently snacking on nutrient-poor savoury foods may increase everyday mental loss, which in turn reduces psychological health. "

"It is possible that changing what we snack on could be a really simple way to improve our mental health. It is also possible that the future limit of processed （特殊处理的） snacks at checkouts, could not only improve the country's physical health, but mental health too. "

"Overall, it's definitely worth trying to get into the habit of reaching for the fruit bowl."

Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan. 

Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious (难为情的) when they're in poorly lit places—and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness. 

Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it's time to repaint, go blue. 

Don't forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal. 

Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass. 

Leg over leg, a furry brownish—black spider pulls on a single silk thread, tightening the frame of its web. It pulls and pulls and it waits. Minutes pass, sometimes hours. Then, when an unsuspecting insect flies by, the spider releases the thread, springing itself and its satellite dis—shaped web toward its prey. All of this happens in the blink of an eye. 

Those eye—watering numbers led Georgia Tech chemical engineer Saad Bhamla to wonder：How are these tiny spidersachieving such fast movements？Then he started to investigate. He checked the literature and found only a few papers. The papers were decades old and only described the slingshot motion, not the speeds or G—forces the spiders experienced. So Bhamla enlisted the help of his assistant, Symone Alexander, and together they "went out hunting for spiders in the Amazon rainforest, " Alexander says. 

After locating one of the spiders, which measures roughly 2 millimeters in length, the researchers would set up portable high —speed cameras with special lenses and record its motions. Then, either Alexander or Bhamla would snap their fingers (打响指) to get the spider to launch itself through the air. Only later did the pair learn that a human finger-snap closely matches the frequency of a buzzing mosquito—and that seemed to be the only frequency that set the spiders' spring off. "It's just amazing that we can snap our fingers and get this magical thing, "Bh am la says. Analyzing the footage, Alexander and Bhamla could watch exactly how the spider adjusted itself on the tension line at the front of its web. "The speed and acceleration of this spider are impressive, but so is the fact that, unlike most web-building spiders, it's actively hunting, "Bhamla says. "It's changed the function of its web, " he says. "Instead of waiting for something to bump into it, the spider is going after things. . . actually catching flying insects in midair. "

Honesty, considering as a good quality, is of vital important. Honest people win respect while a liar is looked down because dishonesty results in distrust and even ruins one's name. So how to be the honest student? Firstly, don't copy homeworks or cheat in the exam. Beside, you'd better to keep your promise and try to do things well. More importantly, tell the truth instead of lies. Only in this way can you make progress in your studies and made more friends. If you're honest with other, you'll be treated the same way. There is no doubt whether honest students will have a bright future.

Our brain is changing (constant). Adults lose thousands of brain cells every day as part of the natural aging process. But here is good news. Scientists used to think that lost cells couldn't (replace), but the latest research shows they were wrong. Adults even generate new brain cells well into their eighties. However, that doesn't happen its own. You have to help this process along.

The brain (account)for just 2 percent of total body weight, it requires up to around 20 percent of the body's blood supply. Why? Blood carries oxygen and sugar, which are the fuels (need) to keep all brain cells working. Blood circulation also removes harmful substances.

In short, good circulation is vital to brain health. If you're suffering from brain fog or finding hard to concentrate, poor circulation is probably to blame.

What can we do? One option is (take) a walk. Exercise can boost the circulation of blood to the brain. That is why exercise has been linked with more new ideas and greater (creative). Next time you hit a mental block, do your brain a favor and go for a walk near your office. When you get back to your desk, make sure you're sitting up straight with your shoulders back and your neck long. That's by far the (simple) way of keeping blood flowing to your brain.

In January 2023, I was commuting (通勤) from Brooklyn to New Jersey. With two little kids and a busy business, a quiet train ride felt like a mini1  . Yet I found myself spending that 2  time scrolling (浏览) through social media feeds. 

One day, I 3 my phone and started writing thank-you notes to people who had 4 to a money-raiser I had organized. Getting off the train, I was in a noticeably 5  mood. The next day, I wrote more 6  and felt the same. Something 7  . What if I kept it up?

I decided to write one thank-you note for every day. I had no shortage of people I was 8  to. I picked out a different 9  for each month. January was charity. February would be neighbors, and I thought of a dozen names immediately. I remembered when the owners of our 10  bookstore let me and my son, Henry, 11 before the store opened and 12 to play his favorite soundtrack. I 13 when our babysitter dropped off some board games for our 14 .

Writing the notes wasn't that 15 : Each was two or three sentences long, taking just a few minutes. I 16 on the person I was writing to and what I wanted to say, and the words came fairly 17 . That focus felt refreshing.

I eventually 18 why this task was the perfect cure to my social feeds. Scrolling through Instagram, I was admiring others' 19 . However, writing thank-you notes was an act of 20 and honoring my own life.

Lizzy Greene's official website says it all: "Actress, Artist & Animal Lover. " At 13, Lizzy has performed in children's theater, and she is a trained gymnast. She is most known for her role as Dawn Harper on Nickelodeons Nicky, Ricky, Dicky & Dawn. Now Lizzy is taking on another role—as a voice for animals.

She grew up with dogs, and her family's pet is a 110-pound German shepherd(牧羊犬) named Jett. On the show, Lizzy shares the screen with a lovable 20-pound dog named Squishy Paws. In second grade, she stationed herself outside her school to ask for donations (捐款) to a local animal shelter.

Now Lizzy is also speaking out for farm animals. She's recently joined The Humane Society of the United States, Meatless Monday movement. She encourages young people to take a break from eating meat on Mondays. And she's encouraging the under-20 crowd to take part.

Lizzy knows that raising animals for meat causes pollution, uses a lot of natural resources (资 源) like water and also harms animals.  Choosing meat-free meals one day a week is also a great way to feel healthy.

Many K-12 schools, universities and hospitals nationwide have started Meatless Monday programs.

"It's so easy to love animals." Lizzy says. For some kid-and-animal-friendly meatless recipes(食谱), visit humonesociety. org/kindnezws.

A. It's easy to eat animal-friendly foods, too.

B. Lizzy has only just begun her bright career.

C. Animals have always been a big part of Lizzy's life.

D. And Lizzy says she has always wanted to help animals.

E. Cutting meat from our diet once a week helps the environment and animals.

F. Kids'breakfast can be as simple as trying a vegetable burger instead of a hamburger.

G. After the movement, Lizzy says she wants to save a few more lives and force humans to eat healthier.
