The Parthenon(帕特农神庙) in Athens is a building with a long and complex(复杂的) history. Built nearly 2,500 years ago as a temple celebrating the Greek goddess Athena, it was for thousands of years the church of the Virgin Mary of the Athenians, then a mosque (清真寺), and finally a ruin. The building was changed and the sculptures(塑像) much damaged over the centuries. By 1800 only about half of the original sculptural decoration remained.

    Between 1801 and 1805, Lord Elgin, the British ambassador to the Ottoman Empire(奥斯曼帝国), which controlled Athens, acting with the full knowledge and permission of the Ottoman authorities，removed about half of the remaining sculptures from the fallen ruins and from the building itself. Lord Elgin loved Greek history and transported the sculptures back to Britain. The arrival of the sculptures in London had a huge effect on the European public, greatly increasing interest in ancient Greek culture and influencing contemporary artistic trends. These sculptures were gained from Lord Elgin by the British Museum in 1816 and since then they have all been on show to the public, free of charge.

    Since the early 1980s, however, the Greek government has argued for the return of all the Parthenon sculptures in the British Museum. They have also challenged the British Museum Board of Trustees' legal title to the sculptures.

    The British Museum, however, insists that it exists to tell the story of cultural achievement throughout the world, from the dawn of human history over two million years ago until the present day. The museum considers itself an important resource for the world: the breadth and depth of its collection allows the world public to re-examine cultural identities and explore the complex network of interconnected world cultures.

    It also says that, within the context of this unparalleled collection, the Parthenon sculptures are an important representation of ancient Athenian civilization. Each year millions of visitors admire the artistry of the sculptures and gain insights on how ancient Greece influenced — and was influenced by — the other civilizations that it came across.

    Some parents can't resist the strong desire to help their children play hooky (逃学) for a trip. Five-year-old Erica and her siblings Alex, 9, and Kate, 12, missed school in Denver on Aug. 21, 2017. Their father Mr. Reed took them on a camping trip to Halsey to see the solar eclipse (日食). Kate had told her teachers she'd be absent and Mr. Reed let Erica's and Alex's teachers know, too. But he didn't ask for permission.

    Mr. Reed has loved astronomy since seeing Neil Armstrong walk on the moon on his sixth birthday. He says, “I want my own kids to have a similar kind of wonderment and hope about future discoveries.”

    Parents often dream of traveling with their children to teach them about science, geography and culture. Many teachers support them, as the Reed children's teachers did. Other teachers were angry about the extra work.

    Teacher Amanda says she feels frustrated when parents take students out of school for family trips. If she sends homework, she finds it's often returned incomplete or incorrect, because the absent student didn't hear her explanation in class. Some students suffer anxiety as they struggle to catch up. Research shows that students who are absent often, for any reason—excused or unexcused—performed more poorly in school.

    Garrick agreed to miss five days of school for the Antarctic trip last year as a senior high school student, however. Managing the homework was a challenge, but it helped him gain time management skills. “And the trip is worth the effort,” he says, “sparking his interest in international relations. You can't really put a price on changing your world view,” Garrick says. “That's what travel has done for me. It has changed how I think about things.”

    Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.

    Perhaps the best answer lies in our genetic makeup as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.

    Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

    Exploration also allows minerals and other potential resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by products(副产品) of technological developments in the space industry!

    While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human beings to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

    While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

    Both honeybees and ants are social insects that live in groups called colonies. They survive by means of their collective intelligence. Their decision-making power is distributed throughout the group; that is, no one ant or bee makes decisions for the group. Instead, they work together. As Deborah M. Gordon, a biologist at Stanford University, says," Ants aren't smart. Ant colonies are."

    The same is true for bee colonies. Although bees and ants are quite different physically, they have a lot in common in terms of their social behavior. Specifically, honeybees and ants have similar roles within the colony, both have communication systems, and both have the capacity for learning.

    Ants communicate by using chemicals called pheromones, which can alert others to danger or to a food source. For example, when worker ants find a promising source, they let the rest of the colony know how to find it by leaving a trail of pheromones on the way back to the colony. The other ants pick up the message using their sense of smell. Bees, on the other hand, use movement to communicate with each other. Worker bees send messages to each other by means of a "dance". Different speeds and movements send different messages. For example, when worker bees called scouts go out to find a new home for the colony, they return and do a dance for the other worker bees that indicates the location of the new home and how suitable it is. The faster the scouts dance, the better the new location is.

    Honeybees and ants are both capable of learning. One Chinese study found that bees can be trained to learn and remember a route to a food source. The researchers also found that bees can be taught to recognize hidden objects and use the concepts of "sameness" and" difference" to accomplish certain tasks. Ants take this one step further. Recent American research has shown that ants not only have the ability to learn, but also can teach their foraging skills to other younger ants.

They observed that older ants accompany young ants in search of food and teach them the route and how to avoid obstacles.

    As we can see, the social behavior of honeybees and ants is quite similar. Both coordinate complex actions and accomplish crucial survival tasks by cooperating in groups consisting of many individuals. Unintelligent as they may be as individuals, as groups they often show amazing brilliance as they go about their everyday activities.

Rich as a King

    William 1, who conquered England some 930 years ago, had wealth, power and an army. Yet although William was very rich by the standard of his time, he had nothing like a flush toilet (抽水马桶), paper towels, or riding lawn mower (除草机). How did he get by?

    History books are filled with wealthy people who were poor compared to me. I have storm windows, Croesus did not. Entire nations trembled before Alexander the Great, but he couldn't buy cat food. Czar Nicholas lacked an electric saw.

    Given how much better off I am than so many famous dead people, you'd think I'd be content. The trouble is that, like most people, I compare my wealth with that of living person: neighbors, school classmates, famous TV people. The greed I feel toward my friend Howard's new kitchen is not reduced by the fact that no kings ever had a refrigerator with glass doors,

    There is really no rising or falling standard of living. Over the centuries people simply find different things to feel sad about. You'd think that simply not having disease would put us in a good mood, but no we want a hot bath too.

    Of course, one way to achieve happiness would be to realize that even by today's standards the things I own are pretty nice. My house is smaller than the houses of many investment bankers, but even so it has a lot more rooms than my wife and I can keep clean.

    Besides, to people looking back at our era from a century or two in the future, these bankers' fancy counter tops and my awn worn Formica will seem equally shabby, I can't keep up with my neighbors right now. But just wait.

A group of foreigners visited Weihai, a coastal city, to explore what the rising star in China's tourism market can offer.

Driven by social media and short video platforms, Weihai's tourism industry saw a huge growth, with the city of just 2.92 million residents welcoming over 59 million visits.

Their first stop is the Dongchu Island in Rongcheng, a county-level city in Weihai, where the scenery is characterized by the region's unique seaweed-roofed houses. "I've never seen a roof made of seaweed. I can't believe my eyes at the houses," said Nick Ive, a British editor.

The group then visited the Sanggou Bay Marine Ranch（海洋牧场）, a hot family-friendly tourist destination to experience marine farming. "Visiting Sanggou Bay Marine Ranch was a pleasant experience because I could see and experience firsthan d how the sea fishes are kept," said Desca Lydi Natalia, a journalist with Antara, Indonesia's national news agency. "This experience not only increased my understanding but also provided enjoyment, as I could directly eat clams（蛤蜊） freshly harvested from the sea. I even had the opportunity to feed the seagulls."

Sanggo u Bay Marine Ranch receives about 80,000 visitors every year since it was established in 2015. Visiting the marine ranch has become one of the must-dos in Weihai.

Desca said that her favorite experience was living in a homestay in Weihai. "While staying in a hotel is comfortable, a homestay offers a different experience, especially since the yard is large and full of flowers, making it feel like home. So I chose a homestay,"said the Indonesian journalist. The homestay Desca chose is just a stone's throw away from the beach. Desca said that her country is a maritime country and also has many homestays. "So when I stayed in the homestay, the atmosphere reminded me of Indonesia," she added.
