When you travel in other countries, you'll have to get yourself well prepared to ensure your safety and handle emergencies.

Before you leave, you'd better:

1). Take out medical insurance policy and learn what the plan covers and whether departure or return to the hometown is covered. Figure out payment choices, such as whether you have to speak directly with the insurance company, before or after treatment, whether you have to pay first and get compensation later.

2). Keep up to date on all required vaccinations (接种疫苗) .

3). Learn about the city or area where you are going to travel. Know how to say street names and landmarks in the local language. Figure out unique climate issues such as altitude, seasonal changes, potentially risky animals and insects.

4). Visit some local hospitals and write down addresses in the local language along with emergency entrance locations; do the same for dental/pediatric (小儿科的) services. Get first aid equipment with necessary medications. Take enough prescribed medication from the home country.

5). Carry a card or note written in both English and the local language listing your emergency contact numbers, name, basic medical information such as blood type and allergies (过敏) .

6). Ensure a reliable means of communication is available and carry an extra phone battery and a charger. Ensure that housemaids, drivers, office assistants, those who work or travel know how to call for medical assistance since they may be the only ones available in an emergency.

7). Make sure to bring all documents and visas along with you. Plan your journey carefully and carry copies of documents (ID, insurance policy records, medical records) and keep in a place where someone else could access them in an emergency.

    It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness(荒野).

For Killing Wolves

    In Alaska，the wolf almost disappeared a few years ago，because hunters were killing hundreds of them for sport. However, 1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur．So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply.

    A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life．When the deer can't find enough food，they die.

    If the wolves continue to kill large numbers of deer, their prey(猎物) will disappear some day. And the wolves will, too. So we must change the cycle of life in the wilderness to balance the ecology. If we killed more wolves, we would save them and their prey from dying out. We'd also save some farm animals.

    In another northern state, wolves attack cows and chickens for food. Farmers want the government to send biologists to study the problem. They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population．

Against Killing Wolves

    If you had lived long ago，you would have heard many different stories about the dangerous wolf．According to most stories，hungry wolves often kill people for food．Even today，the stories of the “big bad wolf” will not disappear．

    But the fact is wolves are afraid of people, and they seldom travel in areas where there is a human smell．When wolves eat other animals，they usually kill the very young, or the sick and injured. The strongest survive. No kind of animal would have survived through the centuries if the weak members had lived. And has always been a law of nature.

    Although some people say it is good sense to kill wolves，we say it is nonsense! Researchers have found wolves and their prey living in balance．The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life.

    The real problem is that the areas where wolves can live are being used by people. Even if wilderness land is not used directly for human needs, the wolves can't always find enough food. So they travel to the nearest source, which is often a farm. Then there is danger. The “big bad wolf” has arrived! And everyone knows what happens next.

    “Helicopter parent” may not sound pleasant, but given the chance, most parents would probably prefer a vehicle to zoom (快速移动)little ones between school, football practice and piano lessons. Getting children where they need to go is a huge task and expense, especially in homes where both parents work. Hailing rides (专车服务)through firms like Uber and Lyft has made life more convenient for adults. But drivers are not supposed to pick up kids who travels without an adult aside (although some are known to bend the rules).

    Children represent a fresh-faced opportunity. Ride-hailing for kids could be a market worth at least $50bn in America, hopes Ritu Narayan, the founder of Zum, one of the startups in want of the prize. These services are similar to Uber's, except they allow parents to schedule rides for their children in advance. Children are given a code word to ensure they find the right driver, and parent sreceive warnings about the pick-up and ride, including the car's speed. These services promise more careful background checks finger printing and training than typical ride-hailing companies.

    Annette Yolas, who works in sales at AT&T, says that she spends around $200 a month on Hop Skip Drive, a service that operates in several markets in California, for her three kids to get to the school bus on time and to ballet practice. She says it has been a “life-saver” by allowing her to work longer hours. Meanwhile, kids avoid the embarrassment of a relative pulling up at school. But ride-hailing firms for kids may end up like the children in Neverland, and never fully grown. They face several challenges. One is finding enough drivers. All users need rides during the same limited set of hours: before and after school, which makes it hard to offer drivers enough work. It can also be challenging to persuade parents, who have drilled it into children never to get in a stranger's car.

    And while ride-sharing companies can annoy adult passengers by cancelling or being late, such behavior can be a disaster when children are involved. Shuddle, an early entrant in the taxis-for-kids business, which shut down in 2016, had only two out of five stars on Yelp (点网站)for that reason， and lots of negative reviews from parents. It had made money on rides mainly by raising prices ever higher.

    Shuddle's failure has not discouraged Uber itself, which is expected soon to launch a pilot programme for teenagers under 18. Parents may be happier to use services they are familiar with. But Uber's entrance is likely to add to the struggle of child-focused ride-hailing businesses as they compete for customers and new funds.

    Let us all raise a glass to AlphaGo and the advance of artificial intelligence. AlphaGo, DeepMind's Go-playing AI, just defeated the best Go-playing human, Lee Sedol. But as we drink to its success, we should also begin trying to understand what it means for the future.

    The number of possible moves in a game of Go is so huge that in order to win against a player like Lee. AlphaGo was designed to adopt a human—like style of gameplay by using a relatively recent development--deep learning. Deep learning uses large data sets," machine learning" algorithms （计算程序） and deep neural networks to teach the AI how to perform a particular set of tasks. Rather than programming complex Go rules and strategies into AlphaGo DeepMind designers taught AlphaGo to play the game by feeding it data based on typical Go moves. Then, AlphaGo played against itself, tirelessly learning from its own mistakes and improving its gameplay over time. The results speak for themselves.

    Deep learning represents a shift in the relationship humans have with their technological creations. It results in AI that displays surprising and unpredictable behaviour. Commenting after his first loss, Lee described being shocked by an unconventional move he claimed no human would ever have made. Demis Hassabis, one of DeepMind's founders, echoed this comment:"We're very pleased that AlphaGo played some quite surprising and beautiful moves."

    Unpredictability and surprises are—or can be—a good thing. They can indicate that a system is working well, perhaps better than the humans that came before it. Such is the case with AlphaGo. However, unpredictability also indicates a loss of human control. That Hassabis is surprised at his creation's behaviour suggests a lack of control in the design. And though some loss of control might be fine in the context of a game such as Go, it raises urgent questions elsewhere.

    How much and what kind of control should we give up to AI machines? How should we design appropriate human control into AI that requires us to give up some of that very control? Is there some AI that we should just not develop if it means any loss of human control? How much of a say should corporations, governments, experts or citizens have in these matters? These important questions, and many others like them, have emerged in response, but remain unanswered. They require human, not human - like, solutions.

    So as we drink to the milestone in AI, let's also drink to the understanding that the time to answer deeply human questions about deep learning and AI is now.

Comments on the July Issue of Reader's Digest

    I couldn't agree more with Lee Child, that books are really important. Yes, you can get lost in them but you can also find yourself and new worlds and possibilities in them. Books help us to forget and remember. They remind us both of what's really important and what's not.

    And, as Lee says, they let us hold the whole world in our hands, We can feel the weight of this word, we can mark our favourite spots, add in our own thoughts and see our progress through the pages as the story leads us back home, allowing us to re-find ourselves along the way.

    Brian Blessed's I Remember was most enjoyable. I love Brian, a popular actor of stage and screen. It was interesting to learn more about his life. I noted how he enjoyed being involved in the Space Program, doing 600 hours training in Moscow and I have to agree with his thought："We need to get out to Mars because the Earth has got to rest." Mars has always been a source of inspiration for explorers and scientists.

    I was thrilled to read author Lee Childs If I Ruled The World. I was most impressed that he wanted to make teachers the most respected and highest paid professionals.

    I work as a teaching assistant in a primary school and have done so since my youngest daughter began school 12 years ago. Until then I had no idea just how much planning was involved in each lesson and how much patience was required in a class of 30 children! I also agree with Lee that there's nothing more rewarding than finishing a good book.

Njobati, a young woman from Cameroon, faced a challenging journey when she moved from her English-speaking area to a French-speaking area of the country to attend university. The sharp differences between these areas, once part of the British and French empires, made it difficult for her to fit in, which led her to examine her own identity—who she truly was. 

Seeking guidance, she turned to her grandfather who also felt disconnected from his own culture. He expressed sadness about what the Nso had lost both culturally and materially, including Ngonnso statue. Ngonnso was the founder of Nso dating back to the 14th Century, whose statue was an important cultural symbol for the Nso. However, it was taken by the Germans in 1902 and has been housed in Berlin's Ethnological Museum ever since.

Inspired by her grandfather's desire and saddened by the loss of culture, Njobati made a promise to bring back the statue. She believed it would not only achieve her grandfather's wish but connect her with her Nso heritage again.

Njobati did many researches about the statue and former unsuccessful attempts. She realized that restitution ( 归还) was actually about facing the colonial ( 殖民主义的) past. Njobati decided to try differently. To gather support online and offline, Njobati began a grassroots campaign. She organized meetings in community halls and churches, met people one-on-one, and used the power of social media. Through Twitter, she established contact with the Ethnological Museum. 

Njobati's tireless efforts paid off. She was told that a decision about Ngonnso statue was coming, which was an important moment for her.

"Finally, this is happening. Not just for me, but for the Nso people, and for Cameroon, " She cried. "This also lends a hand to other communities that are seeking justice for stolen culture relics. "
