Land Art, sometimes referred to as Earth Art or Earthworks, is a form of art which involves using physical landscapes to create art, taking art out of the museum and into the outside world. Modern Land Art movement really got going in the 1960s when American artists began creating Land Art on a large scale. Today, works of modern Land Art can be seen all over the world, sometimes right alongside much older pieces of Land Art created by people who lived thousands of years ago.

    Land Art, which is not necessarily unchangeable, can take a number of forms. For examples, in 1970 Robert Smithson created the Spiral Jetty（螺旋状防波堤）, made of a collection of stones and mud, in the Great Salt Lake. The American artist made a large jetty in a spiral shape which sticks out into the waters of the lake.

    Reshaping the landscape is a common characteristic of Land Art, which can be created by moving parts around. People can also add things to the environment to create Land Art, like salt, which is added to the Spiral Jetty. It is possible to use plants. In all cases, Land Art is immovable.

    Land Art is designed to gradually form, change, and eventually decay（衰落）. That's one of the biggest differences between Land Art and most of the art one sees in the museums. Some works of art can exist only for a few hours or days. Others are exposed to rain and wind so that they develop and decay over time, which is part of the attractiveness in the eyes of the artists.

    My family was gathered for a barbecue when the discussion arose about a celebrity who earned a large amount of money. The major criteria for receiving millions of dollars seem to be determined by how much the audience will pay to watch the performer achieve.

    The discussion led to a sudden self-questioning. Why did I choose teaching for a career? I half-listened to their conversation as I pondered the answer.

    I remembered my three children watching me spend nights planning for my class. I remembered how they intently listened to my frustrations concerning materials, procedures and the amount of responsibility that seemed to endlessly be thrust into the laps of classroom teachers. I remembered when it came time for each of my own children to choose a profession. How I waited to hear if any had plans to follow Mom into teaching. Long considerations held no mention of anyone becoming a teacher.

    Dessert was being served, and everyone was still involved in the discussion of the enormous salary of one individual, when the phone rang. My husband handed the phone to me.

"Hello, this is Bonnie Block," I said.

"Is this the Bonnie Block who used to teach kindergarten?"

    A nervous sensation swelled in me, and my mind raced with memories of those days long ago.

"Yes!" I exclaimed with a lump in my throat. It seemed like forever as I waited anxiously to hear what the caller would say next.

"I am Danielle—Danielle Russ. I was in your kindergarten class."

    Tears of surprise and joy rolled down my flushed cheeks.

"Yes," I uttered softly as I remembered that darling, wonderful child.

"Well, I am graduating from high school this year, and I have been trying to find you. I wanted you to know what a difference you made in my life."

She proceeded to give details. My influence on her wasn't limited to kindergarten but remained a strong motivating force when she needed a coach to help her meet a challenge. "I pictured you praising and encouraging me all the way."

    Why choose teaching?

    The pay is great!

    An upset little boy wanted to meet God. He thought it was a long trip to where God lived, so he packed his suitcase with a bag of potato chips and a six-pack of root beer and started his journey.

    When he had gone about three blocks, he met an old woman sitting on a park bench alone. The boy sat next to her and opened his suitcase. He was about to drink his root beer when he thought that the old lady might be hungry, so he offered her some chips. She gratefully accepted it and smiled at him. Her smile was so pretty that the boy wanted to see it again, so he offered her a root beer. Again, she smiled at him. The boy was delighted! They sat there all afternoon eating and smiling.

    As dusk fell, the boy got up to leave; but before he had gone more than a few steps, he turned around, ran back to the old woman and gave her a hug. She gave him her biggest smile ever.

    When the boy opened the door to his own house, his mother was surprised by the look of joy on his face. She asked him, “What did you do today that made you so happy?” He replied, “I had lunch with God”

    Meanwhile, the old woman, also returned to her home with joy. Her son was stunned by the look of peace on her face and he asked, “Mom, what did you do today that made you so happy?” She replied, “I ate potato chips with God.”

    Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment or the smallest act of caring, all of which have the potential to turn a life around.

    LONDON­Britain prepares for a vote Thursday that will decide whether it leaves the European Union. The debate has centered on immigration and economic security. Both sides have lowered the tone of their arguments after a three­day suspension(暂停) of campaigning that followed the murder of an anti­Brexit lawmaker, an incident that polls(民意调查) suggest has shocked many previously undecided voters who now say they will vote to remain.

    These are uncertain times in a nation whose economy is the second largest in the European Union. The risks are huge. There are warnings that leaving the 28­member group may cause the British pound to lose 15 percent of its value and bring the resignation(辞职) of David Cameron, the country's prime minister; his stay or not depends on whether Britain listens to him and votes to remain.

    For months, the Leave campaign has been hitting the streets. Its arguments are based largely on immigration, and the belief that Britain has handed control of its borders(边界) to a European super state: "The U.K. has lost control over migration. We have to accept anyone into this country if they have an EU passport, no matter if they have a criminal record or not. We are not allowed to say 'no' to people and that is damaging for the security of the U.K., but it is also putting pressure on jobs and opportunities for young people," said Tom Harwood, a Brexit campaigner.

    The murder of Jo Cox, an anti­Brexit, pro­immigrant lawmaker by a far right extremist(极端分子) with a history of mental problems had a serious effect on both campaigns, and on voters.

    Polls since the June 16th murder showed the Leave camp losing ground, but with both sides still very close on a referendum(全民投票) that many believe could change the course of European history.

    A recent documentary produced by the British Broadcasting Corporation (BBC) has caused a stir in China and in the UK.

    The documentary, titled Are Our Kids Tough Enough? focuses on five Chinese teachers who are sent to teach 50 UK teens at a school in Hampshire.

    The teachers instruct the students for a month. The pupils are then tested, and the results are compared to the ones of those who have continued in the regular UK education system. The idea is to see if the Chinese method improves academic performance.

    The Chinese teachers use their own teaching methods but receive strong resistance from the students. A clip from the documentary online shows some problems, with Chinese teachers calling their students lazy and lacking in discipline, while the students say the high pressure and harsh teachers are driving them crazy.

    This has aroused a new debate in both China and the UK, with some arguing the teenagers need more regulation and discipline. Others say Chinese methods encourage rote learning (死记硬背) instead of independent thinking. For instance, Chinese language teachers should do more than pass on knowledge about words and characters. They should inspire students, helping them feel the sentiment from Chinese literature. This is a higher level of teaching.

    Yang Dongping, dean of the 21st Century Education Research Institute, says, "The Chinese teaching methods are designed to strictly train the majority. Foreign teaching methods, however, are more natural and relaxing, and designed to inspire students' interest in learning. Education methods are based on culture. That is why a successful education method in one place may not work that well when simply 'transplanted' into another place."

    Yang Dongping says, "The documentary does reflect some problems rooted in traditional Chinese teaching methods. Nobel prize winner, Yang Zhenning, gave a very fair comment on this issue. He said the Chinese-style education method works for most ordinary qualified students effectively, helping them reach high standards. However, it may weaken the training for high-potential outstanding students."

On a recent Wednesday, archaeologists announced a groundbreaking discovery that challenges our understanding of early human capabilities. They have unearthed what is believed to be the oldest wooden structure ever found, dating back nearly half a million years. This discovery at Kalambo Falls in northern Zambia, near the border with Tanzania, suggests that our ancestors were more technologically advanced than previously thought.

The wooden structure, which is exceptionally well-preserved, dates back at least 476,000 years. This timeline predates the emergence of Homo sapiens, as detailed in a study published in the journal Nature. The wood shows evidence of having been cut and shaped using stone tools, indicating a level of craftsmanship that was not previously attributed to these early humans.

The structure, which is thought to have functioned as a walkway or platform elevated above the seasonally wet ground, demonstrates a purposeful construction technique. A collection of wooden tools, including a wedge and a digging stick, were also found at the site, further supporting the idea of a developed woodworking tradition.

Larry Barham, an archaeologist at the University of Liverpool and the lead author of the study, described the structure as involving "the intentional shaping of two trees to create a framework of two interlocking supports." A notch was cut into one log, and another tree was shaped to fit through this notch, providing stability to the structure.

The use of wood by early humans was already known, but it was typically associated with basic tasks such as starting fires or hunting. However, the discovery at Kalambo Falls indicates a more sophisticated application of woodworking skills. Barham explained, "The structure involves the intentional shaping of two trees to create a framework of two interlocking supports," which required a level of planning and execution that suggests a higher cognitive ability.

The preservation of the wooden structure is remarkable, given that wood typically decays over time, leaving little trace for archaeologists to study. The high water levels at Kalambo Falls are believed to have played a crucial role in preserving the structure for centuries.

These findings from Kalambo Falls not only provide evidence of an early human ability to manipulate their environment but also suggest a more complex cognitive capacity among these early humans than what has been inferred from stone tools alone. Barham concluded, "The finds from Kalambo Falls indicate that these earlier humans, like Homo sapiens, had the capacity to alter their surroundings, creating a built environment." This discovery underscores the need to reassess our understanding of early human technological and cognitive development.
