1 . Wouldn’t it be wonderful to travel to a foreign country without having to worry about the headache of communicating in a different language?

In a recent Wall Street Journal article, technology policy expert Alec Ross argued that, within ten years or so, we would be able to communicate with one another through small earpieces with built-in microphones. That’s because technological progress is extremely fast. It’s only a matter of time. Such is the belief among certain parents that the technology is imminent and they’re wondering if their kids should learn a second language.

It’s true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at translating “Noes Bueno dormer mucho” into “It’s not good to sleep too much”. Replacing a word with its equivalent (对等词) in the target language is actually the easy part of a translator’s job. But even this seems to be a difficult job for computers.

It’s so hard for computers because translation doesn’t — or shouldn’t — involve simply translating words, sentences or paragraphs. Rather, it’s about translating meaning. And in order to infer meaning from a specific expression, people need to understand a lot of information all at once. Think about all the related clues that help us understand what someone is trying to say: volume, gesture, situations, and even your culture. All are likely to convey as much meaning as the words you use.

Therefore, we should doubt a machine that can’t understand our world like we do. If people from different cultures can upset each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully take our place.

2 . Is It Worth Buying Organic Food?

Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.

The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”

For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.

While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.

Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

3 . Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website Book Crossing.com turns the page on the traditional idea of a book group.

Members go on the site and register (登记) the books they own and would like to share. Book Crossing provides an identification number (识别码) to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

Bruce Pederson, the managing director of Book Crossing, says, “The two things that change your life are the people you meet and books you read. Book Crossing combines both.”

Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

People who find a book can also leave a journal entry describing what they thought of it. E— mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

Book Crossing is part of a trend (趋势) among people who want to get back to the “real” and not the virtual (虚拟).The site now has more than one million members in more than one hundred thirty—five countries.

4 . John von Neumann was the oldest of 3 children of a banker, and his speed of learning new ideas and loving problems stood out early. At 17, his father tried to persuade him not to become a mathematician because he might lead a poor life being a mathematician, so von Neumann agreed to study chemistry as well. In 1926, at 23, he received a degree in chemical engineering and a Ph. D. in mathematics. From then on, mathematics provided well enough for him, and he never had to turn to chemistry.

In 1930, von Neumann visited Princeton University for a year and then became a professor there. His first book was published in 1932. In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics (Einstein was one of the others).

World War Ⅱ hugely changed von Neumann’s areas of interest. Until 1940 he had been a great pure mathematician. During and after the war, he became one of the best mathematicians who put mathematical theories into practice. During the last part of the war, he became interested in computing machines and made several fundamental contributions. After the war, von Neumann continued his work with computers, and was generally very active in government service. He received many awards, was president of the American Mathematical Society and was a member of the Atomic Energy Commission. He died of cancer in 1957.

Von Neumann made several great contributions and any one of them would have been enough to earn him a firm place in history. He will be remembered as one of the greatest minds of the 20^th century.

Von Neumann really was a legend in his own time, and there are a number of stories about him. His driving abilities is a part of his legend. He reported one accident this way: “I was driving down the road. The trees on the right were passing me in an orderly fashion at 60 miles per hour. Suddenly one of them stepped in my path.”

6 . Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.

Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1, 500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-­year-­old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e­mail to “speak” with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast­food restaurant or under the trees — anywhere at all!

Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher­education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too.

At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”

7 . Back in the early 2000s, lots of people couldn’t have imagined life without alarm clocks, CD players, calendars, cameras, or lots of other devices. But along came the iPhone and other smartphones, and they took over the functions of dozens of things we used to think were essential.

The smartphone story could even be a model for fighting climate change; not because smartphones use a small part of the energy of all the things they replace - although they do-but because they represent a different approach to design in general. And that approach is to focus on function rather than form. That requires focusing on understanding the underlying problem，and then engineering a wide range of potential solutions. This approach could revolutionize how we think about energy efficiency.

Traditionally, improvements in energy efficiency have mostly focused on individual devices, which can be quite fruitful. But focusing on individual devices is like if Apple had spent effort inventing a better alarm clock, a better CD player, a better calendar, and a better camera. Now with an iPhone, we don’t need the standalone(独立运行的) devices at all, because it can function as all of them.

So when it comes to using energy efficiently, rather than just installing a more efficient heater，some people have focused instead on the desired function: staying warm. They designed and coated their house so well that they could get rid of their heater altogether, letting them heat their house with 99% less energy.

In the same way, rather than just making cars more efficient, what if we focus on the desired function-getting where we want when we want-and create an efficient transportation system where we can drive less or get rid of our personal cars entirely?

The most energy efficient car or heater is no car, or no heater, while still being able to get around and stay warm. In other words, it’s not thinking efficient, it’s thinking different.

8 . There is an old Chinese proverb that states “One generation plants the trees; another gets the shade,” and this is how it should be with mothers and daughters. The relationship between a mother and a daughter is sometimes confusing. The relationship can be similar to friendship. However, the mother and daughter relationship has unique characteristics that distinguish it from a friendship. These characteristics include a hierarchy (等级) of responsibilities and unconditional love, which preclude mothers and daughters from being best friends.

Marina, 27 years old, said, “I love spending time with my mom, but I wouldn’t consider her my best friend. Best friends don’t pay for your wedding. Best friends don’t remind you how they carried you in their body and gave you life! Best friend: don’t tell you how wise they are because they have been alive at least 20 years longer than you.” This doesn’t mean that the mother and daughter relationship can’t be very close and satisfying.

While some adult relationships are still troubled, many find them to be extremely rewarding. This generation of mothers and adult daughters has a lot in common, which increases the likelihood of shared companionship. Mothers and daughters have always shared the common experience of being homemakers, responsible for maintaining and passing on family values and traditions. Today contemporary mothers and daughters also share the experience of the workforce and technology, which may bring them even closer together.

Best friends may or may not continue to be best friends, but for better or worse, the mother and daughter relationship is permanent, even if for some unfortunate reason they aren’t speaking. The mother and child relationship is closer than any other. There is not an equal relationship. Daughters should not feel responsible for their mother’s emotional well-being. It isn’t that they don’t care deeply about their mothers. It’s just that they shouldn’t be burdened with their mother’s well-being.

The mother and daughter relationship is a relationship that is not replaceable by any other. Mothers never stop being mothers, which includes frequently wanting to protect their daughters and often feeling responsible for their happiness. Mothers always “trump (胜过)” friends.

9 . There is more of a connection between food and culture than you may think. On an individual level, we grow up eating the food of our culture. It becomes a part of who we are. Many associate food from our childhood with warm feelings and good memories and it ties us to our families, holding a special and personal value for us. Food from our families often becomes the comfort food we seek as adults in times of frustration and stress.

On a large scale, traditional food is an important part of culture. It also operates as an expression of cultural identity. Immigrants bring it wherever they go, and it is a symbol of pride in their culture and means of coping with homesickness.

Many immigrants open their own restaurants and serve traditional dishes. However, the food does not remain exactly the same. Some materials needed to make traditional dishes may not be readily available, so the taste and flavour can be different from what they would prepare in their home countries. Additionally, immigrants do not only sell dishes to people from the same countries as them, but to people from different countries. Therefore, they have to make small changes in the original dishes to cater to a wider range of customers. Those changes can create new flavours that still keep the cultural significance of the dishes.

We should not only embrace our heritage (传统) through our culture’s food, but also become more informed about other cultures by trying their food. It is important to remember that each dish has a special place in the culture to which it belongs, and is special to those who prepare it. Food is a window on culture, and it should be treated as such.

10 . A British friend told me he couldn’t understand why Chinese people love eating sunflower seeds(嗑瓜子) as a snack so much.“I’ve met a lot of older Chinese and many have a crack in their front teeth, I believe that’s from cracking the seeds,”he said.

I had never noticed the habit, but once he mentioned it, I suddenly became more aware, I realized that whenever I’m watching TV or typing a report, I always start mindlessly cracking sunflower seeds. My friend doesn’t like sunflower seeds, and, to him, it seems unnecessary to work so much just to get one small seed.

When we were young, the whole family would usually get together for Chinese New Year. Then, we all lived close to one another, usually in a small city, and sometimes even neighbors would go door-to-door on Chinese New Year’s Eve to check out what every household was making.

I remember my parents would be in the kitchen cooking. Out in the living room, a large table would already be laid out, complete with fancy tablecloth, ready-made dumpling fillings, and dishes full of candy, fruits and sunflower seeds. Some of the dishes were to be offered to our ancestors later, while others were for neighbors and children to eat before the evening feast. I must have learned how to crack sunflower seeds back then.

I don’t think it’s right to criticize one’s choice in food or eating habits, no matter how strange they may seem.

It’s not only in China. When I went abroad, I found people had all sorts of strange habits when it came to food. In Denmark, they put salted red fish on bread and eat it for dinner, no matter how much it ruins your breath. They think it’s a delicacy(美味佳肴), and it’s connected to their certain culture. I think it’s a wonderful tradition.
