Art comes in two main categories: realistic and abstract. Realistic art aims to show real-life scenes, people, and objects exactly as they appear. It involves paying close attention to details, making things look like photographs.. It's more about expressing feelings, emotions, and ideas.

Realistic art is easy to understand. Viewers can easily recognize what is portrayed. Take the Mona Lisa, for example一it's a realistic painting of a lady with a mysterious smile. ，helping us to learn about the past.

Unlike realistic art, abstract art is more about being creative. . They use shapes, colors and patterns to express feelings and ideas. Abstract art means different things to different people. Some people enjoy trying to figure out what the artwork conveys.

. Realistic art needs precision in drawing or sculpting to make things look real.

Abstract art requires imagination to use shapes and colors in new ways. Many artists are skilled in both. They create realistic pieces to demonstrate their technical skills and abstract ones to display their creativity.

As for personal preference, some people prefer the clear stories of realistic art while others are attracted to the mystery of abstract art, interpreting meanings in the shapes and forms.

Together, the two kinds of art make the art world diverse and engaging.. 

A. Both types of art take skills to make

B. Photographs preserve faces of folks from long ago

C. Grasping abstract art demands more artistic training

D. Both ways of creating art have their own value and beauty

E. In contrast, abstract art focuses less on realistic appearances

F. Artworks like this tell stories about history and everyday life

G. Artists have the freedom to go beyond real-life representations

Each year, the world loses about 10 million hectares of forest一an area about the size of Iceland一because of cutting down trees. At that rate, some scientists predict the world's forests could disappear in 100 to 200 years. To handle it, now researchers at Massachusetts Institute of Technology (MIT) have pioneered a technique to generate wood-like plant materials in a lab.

This makes it possible to"grow" a wooden product without cutting down trees.

In the lab, the researchers first take cells from the leaves of a young plant. These cells are cultured in liquid medium for two days, then moved to another medium which contains nutrients and two different hormones (激素). By adjusting the hormone levels, the researchers can tune the physical and mechanical qualities of the cells. Next, the researchers use a 3D printer to shape the cell-based material, and let the shaped material grow in the dark for three months. Finally,

the researchers dehydrate (使脱水) the material, and then evaluate its qualities.

They found that lower hormone levels lead to plant materials with more rounded, open cells of lower density (密度), while higher hormone levels contribute to the growth of plant materials with smaller but denser cell structures. Lower or higher density of cell structures makes the plant materials softer or more rigid, helping the materials grow with different wood-like characteristics. What's more, it's to be noted that the research process is about 100 times faster than the time it takes for a tree to grow to maturity!

Research of this kind is ground-breaking."This work demonstrates the great power of a technology," says lead researcher, Jeffrey Berenstain. "The real opportunity here is to be at its best with what you use and how you use it. This technology can be tuned to meet the requirements you give about shapes, sizes, rigidity, and forms. It enables us to 'grow' any wooden product in a way that traditional agricultural methods can't achieve."

"Why does grandpa have ear hair?" Just a few years ago my child was so curious to know "why" and"how" that we had to cut off her questions five minutes before bedtime. Now a soon-to-be fourth grader, she says that she dislikes school because "it's not fiun to learm." I am shocked. As a scientist and parent, I have done everything I can to promote a love of learning in my children. Where did I go wrong?

My child's experience is not unique. Developmental psychologist Susan Engel notes that curiosity defined as"spontaneous (自发的) investigation and eagerness for new information -drops dramatically in children by the fourth grade.

In Wonder: Childhood and the Lifelong Love of Science, Yale psychologist Frank C. Keil details the development of wonder 一 a spontaneous passion to explore, discover, and understand. He takes us on a journey from its early development, when wonder drives common sense and scientific reasoning, through the drop-off in wonder that often occurs, to the trap of life in a society that devalues wonder.

As Keil notes, children are particularly rich in wonder while they are rapidly developing causal mechanisms (因果机制) in the preschool and early elementary school years. They are sensitive to the others' knowledge and goals, and they expertly use their desire for questioning.

Children's questions, particularly those about ""why" and"how," support the development of causal mechanisms which can be used to help their day-to-day reasoning.

Unfortunately, as Keil notes, "adults greatly underestimate young children's causal mechanisms." In the book, Wonder, Keil shows that we can support children's ongoing wonder by playing games with them as partners, encouraging question-asking, and focusing on their abilities to reason and conclude.

A decline in wonder is not unavoidable. Keil reminds us that we can accept wonder as a desirable positive quality that exists in everyone. I value wonder deeply, and Wonder has given me hope by proposing a future for my children that will remain wonder-full.

I used to believe that only words could catch the essence of the human soul. The literary works contained such distinct stories that they shaped the way we saw the world. Words were what composed the questions we sought to uncover and the answers to those questions themselves. Words were everything.

That belief changed.

In an ordinary math class, my teacher posed a simple question: What's 0.99 rounded to the nearest whole number? Easy. When rounded to the nearest whole number, 0.99 = I. Somchow, I thought even though 0.99 is only 0.01 away from I, there's still a 0.01 difference. That means even if two things are only a ltte different, they are still different, so doesn't that make them completely different?

My teacher answered my question by presenting another equation (等式): I = 0.9, which could also be expressed as 1 = .99999.... repeating itself without ever ending.

There was something mysterious but fascinating about the equation. The left side was unchangeable, objective: it contained a number that ended. On the right was something endless, number repeating itself limitless times. Yet, somehow, these two opposed things were connected by an equal sign.

Lying in bed, I thought about how much the equation paralleled our existence. The left side of the equation represents that sometimes life itself is so unchangeable and so clear. The concrete, whole number of the day when you were born and the day when you would die. But then there is that gap in between life and death. The right side means a time and space full of limitless possibilities, and endless opportunities into the open future.

So that's what life is. Obijective but imaginative. Unchangeable but lniess. Life is an equation with two sides that balances isef out. Sill, we can't ever truly seem to put the perfet words to it. So pssibl numbers can express ideas as eually well as words can. For now, let's leave it at that: 1 = 99999... and live a life like it.

The entire town displays the ski-chic atmosphere,hosting dozens of ski and snowboardcompetitions and festivals annually. In the warmer months, more outdoor enthusiasts come outto play. Visitors can try hiking or cycling up the mountains. While Whistler is an ideal vacationspot for the active types, other travelers can enjoy the local museums and art galleries filled withinformative exhibits. Plus, there are family-friendly activities and attractions like summerconcerts, along with plenty of shopping options.

When to visit

The best times to visit Whistler are from June through August and between December and March.

How to get around

The best ways to get around Whistler are on foot or by bike. Or, you can take the shuttlebuses from Whistler Village, which transport visitors to Lost Lake Park and the Marketplace.Meanwhile, having a car will allow you the freedom to explore top attractions like WhistlerTrain Wreck and Alexander Falls without having to spend a lot of cash on a cab.

What you need to know

●Whistler receives feet of snow each year. If you're driving in winter, slow down and make sure to rent or come with a reliable SUV.

●Snowslides are likely to occur on Backcountry routes, so only advanced skiers should take to this off-the-map area.

●Whistler's wildermess is home to many black and grizzly bears. Keep your distance and do not feed them.

I worked at a local station of the Berlin fire department．We got an alert（警报）around 8:25 pm that Friday and rushed to the fire engine, where the printout from the dispatcher（调度员）said there was a nine-year-old boy locked in a safe．

I asked myself: if it were a safe, would it be airtight? I was aware that it might already be too late by the time we arrived．I had to plan for a bad outcome．On the other hand, if we were in time, how long would it take us to open the safe? I knew it would be an incredibly difficult task．It's what safes are designed for—not to be opened．

It took less than five minutes to reach the property．When I saw a woman crying on the street, I knew the situation was serious．She was the boy's mother and she led us into the basement．She told us the boy was alive and we started talking to him; he was very calm．We asked how it had happened: during a game of hide and seek with his five-year-old brother, he had thought the safe would be a good place to hide．

The boy's parents had got the house from his mother's father．The unlocked safe had been there when they moved in and was in an area they didn't use much．The boy's little brother had shut the safe, then, when he couldn't open it again．The only person who knew the combination was the boy's late grandfather．

From the outset, the biggest priority was getting oxygen to the boy．We got oxygen from the hospital．The boy said that he could feel a thin stream of air．I asked his parents if anyone had opened the safe before and they said no．So we had to guess a six-digit code（密码）．We started typing them in—but we had to wait 10 minutes between each attempt before we could try again． So quickly we tried them all．No luck．

What did you have for dinner Tuesday night of last week? If someone （ask）you that question Wednesday morning, you would （possible）have had no problem recalling what you had for dinner the night before．

But as days pass, the memories of all the other meals you （eat）since then start to interfere（干扰）with your memory of that one particular meal．This is a good example of  psychologists call the interference theory of forgetting．Forgetting is the result of （vary）memories interfering with one another．The more similar two or more events are  one another, the more likely interference will occur．

Getting rid of interference altogether is impossible, but there are a few things you can do to minimize its effects．One of the best things you can do is rehearse（排练）new information in order to better commit it to memory．In fact, many experts recommend overlearning important information,  involves rehearsing the material over and over again until it can be reproduced perfectly with no errors．Another strategy for fighting interference is to switch up your routine and avoid （study）similar material back to back．Sleep also plays an essential role in memory （form）．Sleeping after you learn something new is  efficient way to turn new memories into lasting ones．

I used to stutter（口吃）quite badly．I felt very 1 , like I was less of a human being．

I didn't have any 2 when I left special school．So I got a job as a trainee hotel porter．I enjoyed it because I was meeting new people and earning my own 3 ．I felt like a proper adult．But the other men 4 me mentally because of my disability．They'd imitate（模仿）me 5 because of my speech impediment（障碍）．I got very down．I was 6 inside．

The stepping stone to self-belief for me was 7 I got help from KeyRing—an organization which helps disabled people to live 8 ．I couldn't write very well, but I could 9 that．Apps on computers meant I could dictate（口授）my emails．I got the government 10 for disabled people in work．It paid for me to help with paperwork two mornings a week．

11  I heard about a job going at the human rights charity CHANGE．I got an 12  that got me the job of international project consultant．I travel all over the world to 13  professionals to work better with people with learning disabilities．This builds my 14 ．I lost my stutter in the end．

My learning disability was a bit of me, but it doesn't 15 me．It's just a label people put on me．It hasn't stopped me having a life．

The art of learning how to think

Learning how to think is really the whole point of going to university because it is one of the few periods in your life when you get time to do it．

Like any skill, successful thinking takes practice．The more time you spend thinking and the more ideas you come up with, the more likely it is that some of them will be good ones． Your thinking will never improve if it consists entirely of thinking how much of a failure you are．

 Geniuses generally come up with their brilliant innovations by thinking about a subject in lots of different ways and establishing connections between apparently different ideas．On the other hand, there are times when you need to know what you are supposed to be thinking about and why, and to stay reasonably focused．

If you are having trouble thinking, it may be because you lack another skill that would make it easier．It could be that you don't have a wide enough vocabulary to put your thoughts into words． If you share a house with violinists and pianists, you may have trouble hearing yourself think．

One way to sharpen this skill is to think critically about what other people are thinking．Thinking is not always something that needs to be done alone． So, if your housemates ever abandon their instruments, engage them in conversation, look for holes in their arguments, and explain your own．

If you get really good at thinking while at university, you may be able to think of a way to carry that on．

A．Proper thinking is about creating an argument．

B．It enables us to become more independent thinkers．

C．If they're all rubbish, try not to keep thinking about it．

D．And thus it saves you actually doing anything once you leave．

E．You may also be in the wrong environment for productive thought．

F．Having a one-track mind won't improve your power of thinking anyway．

G．In fact, communicating your thoughts can help to develop and clarify them．

Bottled water has long been marketed as a safe drink—if it doesn't come straight from a mountain spring, it's at least clean and free of chemicals．But a new study demonstrates that bottled water may not be so safe when it comes to microscopic plastic pollutants capable of passing into the bloodstream．

For years scientists have raised the alarm over microplastics, which form when plastics break down into increasingly smaller particles（微粒）, ranging from five millimeters down to one micrometer．Previous studies have found that a liter of bottled water can contain tens of thousands of identifiable plastic particles．But they stopped at the one micrometer level due to technological restrictions．

The study used a new technology to find even smaller particles, and detected an average 240,000 plastic particles per liter of bottled water．About 90% of the particles were considered nanoplastics, smaller than one micrometer. Unlike microplastics, they are capable of passing through some organs like lungs into the bloodstream．From there they can stay in the heart muscle and other organs, pass into the brain, and even into the bodies of unborn babies．

So far, little research shows what nanoplastics exactly do once they enter the bloodstream．But there is much evidence that chemicals used in plastic production are bad for human health．Even if nanoplastics themselves are not deleterious, they can serve as carriers for the dangerous chemicals, increasing the risk of cancer and impacting key organs such as the heart．

"There is a huge world of nanoplastics to be studied," said the researchers．Even if nanoplastics make up 90% of the number of plastic particles found in bottled water, they make up far less in mass, they said．However, this fact provides little comfort: It's the numbers rather than mass that matter, and the smaller things are, the more readily they can get inside us．

The impact of technology on language is a topic that often causes concern, with many assuming that it is simply ruining it．However, language experts resist such pessimism, noting that there is little evidence to support the view that speech is getting worse．Gretchen McCulloch, in her book Because Internet, focuses on what can be learned about language from the internet rather than talking about its supposed negative effects．

McCulloch compares studying language online to growing bacteria（细菌）in a Petri dish, where trends emerge and disappear quickly, allowing language experts to observe changes that would otherwise take a considerable amount of time．The influence of strong ties like friends or family vs weaker ties on language change is analyzed, with computer simulations（模拟）revealing that having both strong and weaker ties helps spread updates in a community．

The role of social media platforms in language change is also discussed．Twitter, with its mix of strong and weak ties, is shown to drive more language change than Facebook, which is controlled by stronger ties．Emoji is highlighted as a universal digital expression of gestures, not a language．Additionally, there is evidence that the use of internet "innovations" such as "omg" dates back to pre-computer eras．

McCulloch's book focuses on the birth of a new medium rather than a new language．The rise of mass writing on the internet, characterized by frequent, error-filled, and short-lived communication, challenges traditional ideas about writing's importance．McCulloch suggests future historians should see this as a return to more casual（随意的）language, paying more attention to the value of tools that improve social interaction online．The book argues against the idea that these changes might lead to the end of "real" writing, advocating for an appreciation of anything that enhances human connect ion and the enjoyment of each other's company．

In the joyful summer Chadalavada spent with Jayasree, his grandmother in 2018, the pair watched endless movies．Late one evening, Jayasree, who had recently been diagnosed（诊断）with Alzheimer's, got up in her nightdress and went to make tea at her home in India．After she returned to her bedroom, Chadalavada went into the kitchen to find that his grandmother had left the gas on!

Chadalavada decided to invent a wearable device to help people like his grandmother．Now aged 17, Chadalavada is ready to start making the Alpha Monitor．The device, which can be worn as an armband, sets off an alarm when the wearer with Alzheimer's starts to move and warns a caregiver if the patient falls or wanders off．

Most similar devices run on Wi-Fi or Bluetooth, so when a person moves out of their frequencies' limited range the connection is lost and with it the monitoring．But the Alpha Monitor can detect a person more than a mile away in cities and three miles in the countryside thanks to the long-range technology, known as LoRa, it uses．

Teaching himself with YouTube videos about robotics and electronics, Chadalavada has developed several prototypes（模型）．To understand the needs of people with Alzheimer's, he spent time in a day centre run by the Alzheimer's and Related Disorders Society of India．There, the co-founder told him that the device "had to be something light that can be worn on any part of the body"．She says: "Many patients don't like having to wear a watch and they take it off."

In March, when Chadalavada's school exams are over, he will put the finishing touches to the monitor, with the aim of getting the device ready for market by September．He is confident that it should be sold at an affordable price for most people．

Chadalavada hopes to study robotics at a university abroad．His aim is simple: "I want to create products to help people in India for the whole world."

Is it possible to build muscle and meanwhile lose fat? Please allow us to bring the following two facts to your attention first．

Fact1: Losing fat requires a caloric deficit, which means consuming less calories than your body needs so that stored body fat is used for energy instead．

Fact 2: Building muscle requires a caloric surplus, which means consuming more calories than your body needs so that new muscle tissue can be created．

And it's this realization that leads those of us who want to build muscle and lose fat ideally at the exact same time to wonder just how we're supposed to make it happen．

The 4-week Online Workout Course professionally designed by Super Fitness will perfectly resolve the conflict, making it possible for you to both build muscle and lose fat．
