People who like travelling have their reasons. They believe that travelling can help them expand their field of view, especially in the geographical and historical sense. They also think that touring will give them more chances to enjoy different kinds of food and experience new things that would never be brought by other activities. But those who dislike travelling also have some reasons.

    Travelling, in my opinion, does more good than harm. Most importantly, it broadens our mind. We can get in touch with other civilizations (文明), cultures, customs and ideas.

    Through history, most people travelled because of necessity (必要性)-not for pleasure. People travelled just in order to remain alive. They searched for food to eat or places to live in. They sometimes ran away from enemies. This is not to say that no one ever travelled just for the fun of it. In ancient times, for example, rich Romans travelled all the way to Greece to take part in the Olympic Games, and festivals. Of course, some people decided to travel just out of curiosity. They wanted to find out what it looked like beyond the horizon (地平线). Also business travel has been going on for centuries. Traders could not only make money but also learn to speak several languages and be introduced to different cultures.

    So, travelling does enrich our mind and draw new ideas to us. There is no doubt that we can get much from it.

    Chinese writer and translator Yang Jiang died early on May 25, 2016 in Beijing at age 104. The longest-living Chinese woman writer, she was known for her modest, subtle and witty writing style.

    Yang became a household name in China for her novels, essays, plays and translated works. Her most popular novel, Baptism, describing a group of intellectuals (知识分子) adjusting to a new society in the early 1950s, has been translated into French and English.

    Yang began learning Spanish in 1959 at age 48, and started to translate Don Quixote in 1962. She was the first to translate Don Quixote into Chinese. The work was stopped twice due to the "cultural revolution". She completed it in 1976, and the Chinese edition was published in 1978 and has sold more than 1 million copies. In that year, the Spanish king and queen visited China, and then-leader Deng Xiao-ping gave the royal couple Yang's translation as a gift. Yang was received by Deng at the Great Hall of the People. While shaking hands, Deng asked her when she had completed the translation. "It's just published," she replied, having no time to tell the full story.

    She was married to Qian Zhongshu, a well-known scholar and author of the best-selling novel Fortress Besieged. Yang's memoir about her family, The Three of Us, written after her husband and daughter died, in 1998 and 1997 respectively, was translated into German.

    Yang never stopped writing. At 94, she started writing the book Walking onto the Edge of Life to reflect on her life. It won China's top book award in 2007. At 100, she was still writing articles for newspapers.

We are what we eat. That is an old expression, but one worth knowing. A recent look at diets around the world shows that people who eat healthy food—and not too much of it—live longer. But which areas of the world have the best diets？Researchers found that foods in some of the healthiest diets—Mediterranean, New Nordic, Japanese and French—may be very different, but they are all heavy on local, seasonal and limit processed foods, which are high in vegetables and seafood and low in red meat.

Mediterranean diet contains lots of fruits, vegetables, whole grains, nuts and olive oil. The diet has proper amounts of fish and poultry (禽肉). Red meat and foods high in sugar and salt are not big parts of this diet.

New Nordic diet has whole grains like oats and rye, vegetables such as carrots, broccoli and eggs, seafood, fruits, oil, low­fat milk and cheese. Very sugary desserts are not common in this diet.

Japanese people are some of the longest­living people on the planet, with women up to 87 years old and men up to 80. The Japanese diet is the reason for such lengths of life. The diet has many foods that are low in calories and high in nutrients. Japanese people eat a lot of seaweed, tofu, rice, vegetables and fish. The tradition there is to stop eating when your stomach feels 80 percent full.

However, French people eat fatty foods but do not get fat. And they live a long time. This phenomenon is called the "French Paradox". The reason why the French eat fatty foods without getting fat may be simple. They eat less. Serving sizes in French restaurants and in products sold in stores are smaller than those in most countries. And generally speaking, most French people do not snack. This means they do not eat food between meals.

I was a lecturer for 10 years when I met my greatest teacher. It wasn't in a 1 but in a hospital. She was my daughter Kelsey.

She was born with congenital cerebral palsy（先天性脑瘫). At four, she still 2 to tie her shoes. It was 3 for her. After three years of 4 , Kelsey made it. Her accomplishment taught me that pace wasn't going to be crucial—achieving goals according to her own 5matters most.

At age 5, she won a battle against cancer. Kelsey 6 through creative play. In the hospital, the game was always "restaurant" with her playing waitress and the rest of us 7 as customers. She enjoyed herself in the 8 for several hours 9 , as if we weren't in the hospital at all. At home, the play turned to "hospital." Her game included medical terms even we adults didn't understand. We'd just play along as she 10 herself in her roles.

At six, she wished to take ballet lessons. I'm embarrassed to admit how much this 11 me. I wasn't just afraid for her body, but for her 12 .

I worried about the 13 she might get from the class. But she wouldn't 14 and the expectation in her eyes 15 all the drawbacks, so we enrolled her in a ballet school.

Kelsey danced with 16 ! Did she fall? Of course. Was she awkward? Very. But she was completely 17 by her situation. The sheer joy of dancing was enough. After four years, she 18 to horse riding. This time, I signed her up without 19 .

Now a seventh grader, Kelsey continues to embrace her life and teach us invaluable 20 about persistence and the power we could never have otherwise.

Kelsey, I'll never have a greater teacher!

Between 1945 and 2000, educators employed a fairly uniform approach. The teacher was the sun in the classroom, and all lessons and activities centered around him or her. Educators stressed the importance of discipline and obedience(服从) within the classroom, and students were expected to follow very rigid standards for behavior and academic performance. The stated goal of this model was to ensure fairness by applying the same expectations; however, the result was that only a few students succeeded while many others were left behind.

When computers and Internet technology entered the classroom a few decades ago, another pattern appeared and progressive educators immediately saw the opportunity to change the way school worked. Instead of needing to focus on the teachers for the vast majority of the day, students could use computers, websites, and even games to learn new materials and improve their skills and knowledge. Not all educators welcomed this shift, however, as some believed it took power and responsibility away from the teachers and cheapened the educational experience for learners.

Over the last decade, two distinct camps of educators have emerged. Tech advocates stress that computers and Internet technology allow students to learn at their own pace in an environment that makes them feel comfortable, while the traditional classroom sets a pace that many learners can't keep up with and often makes students feel uncomfortable. Traditionalists, on the other hand, believe that over-reliance on tech limits students' ability to develop their own knowledge and skills and does little to prepare them for the realities of being adults in the real world.

Regrettably, the inability of these two parties to find an agreement has prevented the growth of our education system. We must learn from what worked in the past while adopting the best of our new technologies to create an education system that reflects our modern world. If we can't get all our teachers on the same page, then we will be at risk of failing future generations.

Edward Ndiritu joined Lewa Wildlife Reserve in central Kenya in 1996 as a rhino monitor. Back then, illegal hunting had greatly reduced the country's black rhino population. Worried that they might become extinct, he worked his way up to lead Lewa's anti-hunting team. In 2015, his team's community-focused conservation method won him the first Wildlife Ranger Award from conservation charity Tusk.

He grew up in a village between Mount Kenya and the Aberdare Forest, which was once a wildlife route for migrating elephants and black rhinos. He saw them disappear gradually. He realized that hunting and the disruptive actions of the community were the reasons. The demand for rhino horn(角), which is very valuable in Asia, drives hunters. They are part of a big and rich crime network. There are people who help them by giving them equipment. In 2011 and 2012, Lewa had many difficulties. They lost rhinos. It was found that those involved in hunting were also linked to human smuggling(走私) and other illegal activities.

The hunting challenge has changed. Hunters now have networks, get information from the local community, and use technology like phones and motorbikes. Edward's team has adapted by using cameras, sensors, trackers, and a system that tells them when and where hunting might happen. They also work closely with the community, which is now the first 

line of defense. Lewa gives agricultural training, medical help, and business support to rural women. This makes locals more likely to report hunting before it happens.

To be a good forest guard, one needs to be honest, tough, and motivated. Edward now knows that making sure the forest guards are happy and well is very important. He is hopeful about wildlife conservation in Lewa. Funding is a problem, but organizations like Tusk are helping. Conservation is about people. Looking after those outside the reserve is necessary for the future of wildlife. Only when communities can live in harmony with the animals they see every day will there be a good future for wildlife.
