When it comes to cultural heritage protection, the Grand Canalof China is probably the world's greatest project of its kind. The big inland waterway system in thenorth-eastern and central eastern plains passes through eight of the country'spresent-day provinces.

The Canal runs from Beijing in the north to Zhejiang Province inthe south. Constructed in sections from the 5th century BC onwards, it wasdesigned as a means of communication in the 7th century AD. The Canal is the world's greatest civilengineering project before the Industrial Revolution.

The Grand Canal reached a peak in the 13th century, providing aninland navigation(航行) networkconsisting of more than 2,000 kilometers of artificial waterways, linking fiveof the most important river basins in China, including the Yellow River and theYangtze. It entered a bid as a UNESCO(联合国教科文组织) culturalheritage site in 2008.

The Grand Canal cultural square is located in Beijing's Tongzhoudistrict. Ever since the Yuan dynasty 800 years ago, the Tongzhou section ofthe Grand Canal has been the life blood of Beijing. Grain and buildingmaterials were all transported to meet the endless demands of the big cities.Even today, the Grand Canal plays a major role in the lives of its citizens.

"I grew up near the Grand Canal. In the past the waterwaywas a lot narrower, but now it's nice and wide and bridges are built over it. Ithink if the bid for world heritage status succeeds, it will greatly makeTongzhou more famous in the world, especially with Tongzhou aiming to be asub-center of the capital Beijing," a citizen said.

The result of the bid is set to be released next week, and nodoubt it will certainly make it into the history books if the Canal is listedas a world heritage site.

    He says the problem with teachers is, “What will a kid learn from someone who chose to become a teacher?” He reminds the other dinner guests that it's true what they say about teachers: Those who can, do; those who can't, teach.

    I decide to bite my tongue instead of biting his and stop myself from reminding the other dinner guests that it's also true what they say about lawyers—that they make money from the misfortune of others.

    “I mean, you're a teacher, Taylor,” he says to me. “Be honest. What do you make?”

    I wish he hadn't asked me to be honest, because now I have to teach him a lesson.

    You want to know what I make?

    I make kids work harder than they ever thought they could.

    I can make a C+ feel like a great achievement and an A－ feel like a failure.

    How dare you waste my time with anything less than your very best?

    I make parents tremble in fear when I call them: I hope I haven't called at a bad time, I just wanted to talk to you about something Billy said today.

    Billy said, “Leave the kid alone. I still cry sometimes, don't you?”

    And it was the bravest act I have ever seen.

    I make parents see their children for who they are and what they can be.

    You want to know what I make?

    I make kids wonder.

    I make them question.

    I make them criticize.

    I make them think.

    I make them apologies and mean it.

    I make them write, write, write.

    And then I make them read.

    I teach them to solve math problems that they once thought impossible.

    I make them understand that if you have brains then you follow your heart and if someone ever tries to judge you by what you make, you teach them a lesson.

    Let me make this simple for you, so you know what I say is true;

    I make a great difference! What about you?

    There are many places to go on safari（观赏野生动物）in Africa, but riding a horse through the flooded waters of Botswana's Okavango Delta must rank as one of the world's most exciting wildlife journeys.

    Several safari camps operate as the base for this adventure, providing unique rides twice a day to explore deep into the delta. The camps have excellent horses, professional guides and lots of support workers. They have a reputation for providing a great riding experience.

    The morning ride, when the guides take you to beautiful, shallow lakes full of water lilies, tends to be more active. It is unlike any other riding experience. With rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face. It is truly exciting. You are very likely to come across large wild animals, too. On horseback it is possible to get quite close to elephants, giraffes and many other animals. The sense of excitement and tension levels rise suddenly though, as does your heart rate, as you move closer to them.

    In the evening, rides are usually at a more relaxed and unhurried pace. With golden light streaming across the grassy delta and the animals coming out to eat and drink____though they are, rides at this time of day are still very impressive. As the sun's rays pass through the dust kicked up by the horses, the romance of Africa comes to life.

    Back at the camp you can kick off your boots and enjoy excellent food and wine. Looking back on your day, you will find it hard to deny that a horseback Safari is as close as you will ever come to answering the call of the wild.

    Now women are free to enter any career that attracts them, and working can bring them pride, confidence and independence. Working women make up nearly half of the U.S. workforce, and 51 percent of professional workers, like doctors, lawyers, nurses and accountants, are female. While climbing the career ladder can be rewarding, it often comes with one big disadvantage: weight gain!

    New research published this week in the International Journal of Obesity shows that working women are more likely to be overweight, and the more you work, the more pounds you're likely to pile on. Like many women, I work... a lot! As a self-employed nutrition communications specialist, I sit at my desk, in front of a computer, for hours on end. Sitting alone is one of the worst things you can do for your health, and it's directly linked to being overweight and increased fatness, so the fact that women in the workforce gain weight isn't that surprising. If you work, you have less time to move around. Obesity researchers are revealing many other ways that employment is harmful to your diet and waistline(腰围).

    In the International Journal of Obesity study, some 9,276 Australian women aged 45-50 had their body weight and employment status monitored for two years. Results? Those who worked more than 35 hours were likely to gain weight compared to those who worked fewer hours or were out of the workforce. What's more, the more hours a woman worked in a week, the more weight she gained.

    The authors of the Australian study attribute weight gain among working women to inactivity, lack of time for food preparation, more use of prepared foods, high levels of stress, lack of sleep and consuming more alcohol. I'll also add in travel, meals eaten out and working at night as other factors that I can find to make balancing work with a healthy diet a challenge.

    I've come back to check on a baby. Just after dusk I'm in a car down a muddy road in the rain, past rows of shackled (戴镣的) elephants, their trunks swinging. I was here five hours before, when the sun was high and hot and tourists were on elephants' backs.

    Walking now, I can hardly see the path with my phone's flashlight. When the wooden fence post stops me short, I point my light down and follow a current of rainwater across the floor until it washes up against three large, gray feet. A fourth foot twisted above the surface, tied tightly by a short chain and choked by ring of metal spikes (尖刺). When the elephant gets tired and puts her foot down, the spikes press deeper into her ankle.

    Meena is four years and two months old, still a child as elephants go. Khammon Kongkhaw, her caretaker, told me earlier that Meena wears the spiked chain because she tends to kick. Kongkhaw has been responsible for Meena here at Maetaman Elephant Adventure, near Chiang Mai, in northern Thailand, since she was 11 months old. He said he keeps her on the spiked chain only during the day and takes it off at night. But it's night now.

    I ask Jin Laoshen, the Maetaman worker, why her chain is still on. He says he doesn't know.

    Maetaman is one of many animal attractions in and around tourist-crowded Chiang Mai. Meena's life is set to follow the same track as many of the roughly 3,800 captive (被捕获的) elephants in Thailand. When Meena is too old or sick to give rides—maybe at 55, maybe at 75, she'll die. If she's lucky, she'll get a few years of retirement. She'll spend most of her life on a chain.

After years of teachers asking for the right answers, students aren't used to someone asking for the wrong ones. Students' failure tends to create mental burden that negatively affects learning. Lifting the burden requires us to face failure bravely and encourage students to accept it as a natural part of getting educated. While educators have to make sure that students have the right content and support to avoid long-term failure, it is just as important to accept mistakes as a normal part of education.

Sadly, our culture is so focused on success or perfection that students generally aren't taught about failure. To fill the gap, I share with students a Samuel Beckett quote "Ever tried. Ever failed. No matter. Try again. Fail again. Fail better". It suggests one becomes better after each failure. I also play a video on game designed by Extra Credits, which shows people can quickly declare their ways as a failure if they don't work out and then learn from. them to move on. Both the quote and the video can help students get a more positive attitude towards failure.

Teachers can help students accept failure better. In her piece "5-Minute Film Festival: Freedom to Fail Forward", Edutopia author Amy Erin Borovoy had a set of videos-and articles on the subject of failure. Borovoy reminds readers that "a true thinker learns as much from failure as from success." Taking these short videos as monthly or weekly reminders can, be a great way to start "how have we failed and what have we learned" discussions with students.

Teachers can actually use a technique called "Effective Failure" to teach about failure at any time. In my writing class, I often have students volunteer to pick out the worst writing of their own. This lets writers deepen their understanding of why a sentence, word choice, or paragraph construction has failed, and it inspires a sincere interest in better writing. This makes failure work well in class.

Also, remember that students are not the only ones who can learn from their mistakes. As those who teach students, we should do that too.
