Every time we get behind the wheel of a car, we put our lives and the lives of others at risk. Self-driving cars are designed to reduce those risks by letting technology control our vehicles.

    Accident rates for self-driving cars have been much lower than the rate, for human-driven cars. {#blank#}1{#/blank#}

    As humans, we can make moral choices in avoiding accidents. To avoid hitting a child, for example, human drivers might sharply turn a car away from the child even if others may be injured. {#blank#}2{#/blank#} Researchers studied this issue. They have developed the Moral Machine website to help explore the choices self-driving cars should make.

    {#blank#}3{#/blank#} You are shown two possible traffic situations and you choose between them. An accident will take place. You choose how many living beings would be hurt or killed.

    In one situation there may be a female doctor, a child, two dogs and a homeless person who would be killed. In the other situation, you might have two babies and a cat who would be killed. {#blank#}4{#/blank#}

    The Moral Machine website has many situations and many possible outcomes. When you click on the situation of your choice, it will be highlighted. {#blank#}5{#/blank#} At the end of the situation, you are shown the results, based on the choices you made. The results show which character you were most likely to save and which character you were most likely to have die.

    Recently there has been a discussion on a website about “what would you miss most and least if you were stuck on a desert island?”

    Here are some of the answers:

Post 1

    Steve USA—Hi, everyone. What would you miss most and least if you were stuck on a desert island? For me, it would be the changing seasons in New England. I guess this will sound stupid but I'd probably miss the rain, too. I wouldn't miss getting up at six every day to go to work, though! What about you?

Post 2

    Tomas Germany—Good question. Steve, I think I'd miss different types of bread, and shopping at the supermarket. I'd miss the food most. What would I miss least? My mobile phone—I'd like to be completely quiet—at least for a little while.

Post 3

    Paola Italy—I would miss the company of people because I know I'd like to have someone to share experiences with. I'd go mad on my own. And I sure wouldn't miss junk mail—I hate coming home every evening and a pile of junk mail in my post box.

Post 4

    Miko Japan—Hi, I would miss Manga cartoon, the Internet and Japanese food, like sushi. I'd also miss TV shows and shopping for clothes… In fact, I'd miss everything.

Post 5

    Roger UK—I would miss my daily newspaper and listening to the news on TV and radio. I'd feel very cut off if I didn't know what was happening in the world. What I'd miss least would be traffic jams in the city, particularly my journey to work.

Post 6

    Jayne Russia—Why hasn't anyone mentioned their family? I'd be lost without my husband and two kids. They're the most important for me. And I can't get started in the morning without a cup of black coffee. I wouldn't miss doing the housework!

Post 7

    Jaime Mexico—It would have to be music. I couldn't live without my music. I wouldn't miss going to school at all or doing homework!

    Do you like air travel with a service dog? Air travel makes some people very nervous. The crowds, the noise and flying itself can cause unease. But there are classes people can take to help them defeat their fear of flying. And, let me introduce similar training for service dogs that suffer the same problem

    Service dogs almost never leave the side of the people they care for. You will see them working on buses, trains and other public transport systems. But the busy environment found at an airport can trouble even the best trained working dog.

    People with disabilities depend on their dogs. They want the animals to safely guide them through security areas. They also need the dogs to remain calm on duty on the plane, even when the flying is not smooth. This takes special training. The Air Hollywood K9 Flight School is one place where such help can be found.

    The school has a piece of equipment that provides the sights, sounds and even the feel of an airplane in flight. It is called a flight simulator, which was built for filming airplane scenes in movies.

    Sandy Alexander has a disability that requires his two-year-old dog, Doc, to be always at his side. Mr. Alexander took the dog to the flight school to get him ready for plane trips. He says Doc did not like the bumpy part of the flight simulation( 模拟).

    Dog trainer Mary Segall is with Canine Companions for Independence. It provides dogs for people with disabilities. Ms Segall says successful training is based on a simple rule: preparation.

    "Dogs need to be exposed gradually and repetitively to stimulation, to the environment, to loud noises, to sounds and to other dogs so that when this experience happens to them on a daily basis, they are able to act in a way that they're used to acting and that they don't get excitable."

    Dog owners who attended the training at Air Hollywood K9 Flight School say they now feel much more at ease about future flight. Their dogs also seem ready for take-off.

    Growing up in the mountainous Sierra de Penamayor, in Asturias, northern Spain, Aladino Montes had been shooting deer ever since he was a child, but his life as a hunter came to an abrupt end 10 years ago, when he met Bambi, an adorable deer that has remained by his side ever since. Aladino has never shot an animal since.

    53-year-old Aladino recalls driving through the mountains in his little jeep, ten years ago, when he saw a couple of cows being followed by a skinny little deer. Deer don't usually hang out with cows, so he approached the animals for a closer look. That's when he noticed that the deer had several wounds and would have probably died without proper medical care. He put the injured animal in his car and drove back to his house where he nursed it back to health. But instead of running back towards the forests, the deer stayed by Aladino's side. They've been best friends ever since.

    He always loved animals, but his father had taught him to hunt deer as a child. He did it for food, not sport, but ever since he adopted Bambi, he hasn't shot a single animal.

    Aladino's cabin sits at 1,140 meters above sea level, offering tourists a beautiful view of the surrounding mountainside. On clear days, one can see all of central Asturias all the way to Gijon, but most people don't travel to Les Praeres for the view, they come to see Bambi, the friendly deer.

    Sometimes, Bambi will walk straight into the bar in search of Aladino and leave everyone with their mouth open, or even let people pet her. But she's always most comfortable at the side of her rescuer. She's so relaxed around him that she makes other deer feel safe as well.

    Confident, smart and high-tech, they're followers of pop culture and know what social networking is all about. They're tweens, children between the ages of 10 and 12. These young people are no longer little kids but they are not yet teenagers, because tweens are in a state of transition (转变).

    The tween years are hard for children. From a social point of view, tweens are dealing with quite a lot. They have to face changing relationships, middle school and a whole lot of pressure (压力) to succeed and fit in. They may become angry over seemingly small things. A bad test grade, an argument with a friend, a bad day on the ball field, or a request to clean a bedroom might set them off.

    Elizabeth Hartley-Brewer, a parenting expert in London and author of Talking to Tweens, says, "The tween years are when young people begin to realize the wider world and to see themselves as separate from their families."

    Right now, tweens' friends are everything to them. It's universal for the age, but they show it in different ways. For boys, the whole friendship thing is through technology and sports. Girls like to talk.

    Tweens are also a hot market. What do tweens consider cool? Music is at the top of the cool list, followed by going to the movies. "Being smart" comes third, tied with video games, followed by electronics, sports, fashion and protecting the environment, according to a report.

    Undoubtedly, tweens have great spending power in the United States. It was the tween market that made Justin Bieber and Harry Potter household names. Retailers(零售商) know tweens are a hot market for clothes, music and entertainment. Tweens have their own sense of fashion and enjoy their own parts of popular culture.

    Carri Kessler and her husband Will named their daughter Ottilie after a friend from the UK, who helped them a lot. However, right after their baby girl was born, the couple noticed a big problem: "No one could remember her name and no one could pronounce it, were going to keep having to introduce her!" Kessler told Today.com.

    The situation then grew worse as Kessler's grandmother admitted to sticking Post-it notes around the house to help remind her of Ottilie's name which can be pronounced either Ott-ill-ee or Oh-TEEL-ya. Three months after Ottilie was born, the Kesslers have decided to legally change their daughter's name. The couple came up with two possible names. They then settled on Margot after talking to a name expert.

    The Kesslers situation is not uncommon as an increasing number of parents experience the same as the Kesslers. According to Baby Center Canada, 11% of its users wish they could change their children's names due to being over popular mispronounced or simply unfitting. Parents care a lot more and think a lot more about names now than their parents.

    To deal with this, a number of name experts now offer services to help parents choose the right name. Couples have also looked for help from the Internet to choose their baby's name. However, parents can change their child's name in the event that they regret their choice. In Canada, the rules vary in each province. For instance, in Ontario, the child must have lived in the province for the past 12 months, or since birth if under the age of one. Each of the child's legal guardians(监护人)must also give permission.
