Painting

    The art of creating pictures using colors, shapes and lines is called painting. Museums and galleries show the paintings of professional (专业的) artists. But painting is also a popular form of entertainment and creative expression.

    {#blank#}1{#/blank#}Experienced painters usually use a brush to apply oil paints to a canvas cloth surface. Young painters usually use watercolors on pieces of paper. Very young children may use finger paints to create paintings.

    Painters can use their art to express devotion to a religion, to tell a story, to express feelings and ideas, or simply to present a pleasing picture. Religious paintings often show a god or a scene from a sacred text (圣典). Other common subjects have been famous legends and events in history, as well as scenes from daily life. Artists also paint portraits (画像), or pictures of people{#blank#}2{#/blank#}All of these types of paintings show the human figure in some way.

    Some kinds of paintings do not focus on people. In landscape (风景) painting the focus is on scenes from nature. Artists also paint still objects such as fruits and vegetables{#blank#}3{#/blank#}Some artists communicate their ideas through pictures that do not represent any object.

    {#blank#}4{#/blank#}Paintings dating back 15,000 years have been found on the walls of caves in France and Spain{#blank#}5{#/blank#} Samples of painted pottery (陶器) from at least 5,000 years ago have been found in China and Iran. The ancient Egyptians decorated their temples with beautiful paintings. People in ancient Greece painted decorative objects such as vases in addition to the walls of temples.

A. These works are called still-life paintings.

B. These works can communicate a special feeling.

C. Humans have been making paintings for thousands of years.

D. People of all ages create pictures using a variety of materials.

E. Cave paintings generally show animals that early humans hunted.

F. The design of a painting is the plan of its lines, shapes and colors.

    Most of us would be traveling for the rest of our lives if traveling abroad were not so expensive. But there is no need for you to cut down on the number of holidays you're having this year. Below are some of the cheapest places to travel to this year.

    Sri Lanka

    Great seafood, beautiful beaches, and amazing jungles await you in Sri Lanka. It is definitely one of the cheaper places to travel to as well. It will be possible for you to live in high-class hotels and resorts for as little as 70 dollars a night! If you don't want to spend that much money, you can find hostels, and smaller hotels for as little as 20 dollars a day. You can just spend the day exploring Anuradhapura or go adventuring in Habarana Lake as well!

    Hungary

    It might be surprising to see Hungary on the list of cheap places to travel to this year. It is located in the most expensive continent on the earth, after all. However, Hungary is the country where you get rooms for as little as 16 Euros, and beer for about 4 Euros each! This is definitely a bargain! You can get a travel card to use the public transport throughout the country, and save quite a few dollars on that as well. Spend a few nights in Budapest or head out to the northern hills where you can hike and swim in the clear lakes!

    Greece

    There was a time when Greece was unbelievably expensive, but due to its recent economic problems, Greece has become quite cheap to travel to. Price of accommodation and food is at an all-time low, so this might definitely be a great time for you to visit! There are some areas of the country that will be expensive like Santorini or Mykonos, but if you just want to explore local Greek culture, you can walk on the streets of Greece, or adventure across the smaller islands around like Kefalonia or Piraeus or Los!

    With Disney parks recently raising their ticket prices to $89 now is the perfect time to start thinking about smaller, regional theme parks. Here are four theme parks where the daily price of adult admission is under $50.

    Luna Park, Coney Island, NY.

    How much you spend in enjoying Luna Park really depends on which rides you choose to go on. For anyone as indecisive as I am, stick with the $29 four-hour Unlimited Luna Park Ride Wristband or the $39 Ride and Play package, a four-hour unlimited ride wristband that comes with a $20 game card.

    Dorney Park, Allentown, PA.

    Dorney Park is a popular theme park located about an hour outside of Philadelphia. Kids love Planet Snoopy, a fun area with attractions centered around the lovable Snoopy. Adult tickets are available online for $39.99 (or at the gate for $49.99) and kids are $27.99 online or ($29.99 at the gate). You can also buy a Starlight Admission ($27.99 online or at the gate), good for visits between 5 p.m. and 10 p.m. during the summer months when the park is open late, or from 3:30 p.m. to 8 p.m. when the park closes earlier.

    Knotts Berry Farm, Buena Park, CA.

    Home to some of the country's craziest rides, Knotts Berry Farm also has calmer, more family-friendly rides. Ages 12-61 get in for $39.99 when tickets are bought online, while children ages 3-11 and adults over 62 pay $26.99.

    Santa Cruz Boardwalk, Santa Cruz, CA.

    Sitting on the warm beaches of Santa Cruz — about 90 minutes south of San Francisco — the Boardwalk is home to big roller coasters, mini-golf, enough food and games to keep people of all ages busy. The best part? An all-day unlimited rides wristband is only $31.95.

    Teenagers around the world can be happy with the news that the brain will ignore parents' order when they tap on their smartphones. A new scientific study from the University College London has shown that humans may temporarily go deaf when they're focusing on something visual at the same time.

    The researchers played the normal-volume sounds in the background. And 13 volunteers experienced inattentional deafness as their visual tasks became increasingly difficult. “We found that when volunteers were performing the demanding visual task, they were unable to hear sounds that they would normally hear,” Maria Chait said in a statement. “The brain scans showed that people didn't filter out the sounds on purpose. They were not actually hearing them in the first place.”

    The findings, published in the Journal of Neuroscience, suggest that the centre of sights and the center of sounds share limited resources. Inattentional deafness is a common everyday experience and the study explains why, according to UCL Institute of Cognitive Neuroscience Professor Nili Lavie.

    If you try to talk to someone focusing on a book, game, or television program and don't receive a response, they aren't necessarily ignoring you. They simply might not hear you at all. This could also explain why you might not hear your bus or train stop being announced if you're absorbed in your phone, book or newspaper. However, some loud sounds will still be able to break through.

    Some situations could become potentially dangerous when the quieter ones go unheard. As you can imagine, in the operating room, when a doctor concentrates on his work, he might not hear the equipment beeping. It also applies to drivers who concentrate on complex directions. Fortunately, experts have given us some useful tips on preventing such situations.

    Cao Zhawa has been planting trees for most of his life. He lives and works in the heart of Mu Us Sandyland, an area in the southwest part of Inner Mongolia.

    In 1958, when he was just 16 years old, Cao started planting trees. Cao's trees now cover an area of more than 1.3 million square meters. Cao's forest is worth an estimated 10 million yuan and can produce 100,000 kilograms oxygen, enough to sustain a full-grown adult for nearly a year.

    Mu Us Sandyland is one of the places in China most affected by erosion(侵蚀) and desertification. The amount of annual rainfall ranges from 150 to 300 millimeters, while evaporation(蒸发) between 2,000 and 3,000 millimeters. Cao recalls that his growing-up was troubled by sandstorms. This was one of the factors that motivated Cao to join and stay on the tree-planting program.

    Popularly known as the "Green Great Wall", the project, which is set for completion in 2050, would be a 4, 800-kilometer greenbelt of trees and shrubs(灌木) protecting the area from strong winds and preventing soil erosion. Since the start of the Three-North Shelter Forest Program, millions of people have joined in and become a vital part of the plan.

    However, the tree-planters face a host of challenges, with watering the most difficult among them. "When I was young, the level of groundwater was high," said Cao, "But with less rain, the trees are hard to plant and keep alive."

    Planting trees has also become harder for Cao as he ages. However, he doesn't want to leave the forest in the care of his children, and he insists the land belongs to the government. "When I die, I just want to be buried under the trees," Cao said. "Then I will be with them forever."

    Some things should just be common knowledge by now. The Earth isn't flat. Nope, your hair and nails don't grow after you die. The holes at the top of Bic biro pens are there so that, if you swallow one accidentally, you can still breathe and won't choke to death. It's debatable whether that last one there is common knowledge or not. A quick Google search of the fact, rewritten as a question, shows articles addressing this point going back several years, with the latest (re)appearing just this week over on ScienceAlert. We suppose it's one of those things that come up from time to time, like what would happen if you attack Yellowstone with a nuclear weapon (not much, as it turns out).

    If you jump over to Bic's website, under their FAQs (frequently asked questions), it quite clearly states: "The reason that some BIC® pens have a hole in their cap is to prevent the cap from completely obstructing the airway if accidentally breathed in. This is requested by the international safety standards ISO11540, except for in cases where the cap is considered too large to be a choking risk."

    That's rather lovely of them. In appreciation of their want to not kill off their more clumsy customers, we thought we'd share a few more random facts about Bic that are probably going to come up in a pub quiz one day. Did you know, for example, that each Bic ballpoint pen can produce at least 2 kilometers (1.2 miles) of ink before it begins to run out? In fact, in 2018, 7,250 kilometers (4,505 miles) of writing tests on such pens were carried out on ballpoint pens, gel pens(中性笔), and rollers to make sure they worked to the highest standard.

    The best part of the Bic site, however, is this rather curious fact: "100 percent of pen balls are made through a highly-controlled process." As opposed to a highly uncontrolled process, involving explosions and bouncy castles and total chaos, we suppose.
