3D printing is becoming more and more popular. We are now able to print things such as clothing, musical instruments and model cars. People and businesses are able to create the things they need very quickly and easily using 3D printers.

But can you imagine printing food? Some scientists are trying to create a new dining experience by doing this. They hope that having a 3D printer in the kitchen will become as common as the microwave or the fridge. Scientists say that they are easy to use: you simply have to choose what you want to eat and put the uncooked food ‘inks' into the printer. You can also change the instructions to make the food exactly how you want it. This means that it would be very quick and easy to create tasty and healthy meals.

Using 3D printers to create your meals would also be saving the environment. There would be less need for traditional growing and transporting as food production would be much simpler. Printing food could also help people who are experiencing the swallowing disorder. They could make the printer to print softer foods so that they would not have trouble swallowing them.

However, some people think that a future of 3D-printed food would cause many problems. It could take away many jobs, including those for growing and transporting food. Likewise, traditional cafés and restaurants might lose business. Also, people are worrying about whether the printed food is nutritious: Is it really possible to get the nutrients we need from foodbased inks? What's more, cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button.

Surfing the Internet for fun will make you a better employee, according to an Australian study.

The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive (有效率的) than those who do not. Study author Brent Coker said "Surfing the Internet at times helps increase an employee's attention."

"People need to relax for a bit to get back their attention," Coker said on the university's website." Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day's work, and as a result, increase productivity (生产效率)," he said.

According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos." Firms spend a lot of money on software to block their employees from watching video, using social networking sites or shopping online," said Coker. "That's not always a good idea."

However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. "Those who spend too much time surfing the Internet will have a lower productivity than those without." he said.

When I was nine years old, I loved to go fishing with my dad. But the only thing that wasn't very fun about it was that he could catch many fish while I couldn't catch anything. I usually got pretty upset and kept asking him why. He always answered, "Son, if you want to catch a fish, you have to think like a fish." I remember being even more upset then because "I'm not a fish!" I didn't know how to think like a fish. Besides, I reasoned, "How could what I think influence what a fish does?"

As I got a little older I began to understand what my dad really meant. So, I read some books on fish. And I even joined the local fishing club and started attending the monthly meetings. I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature. That is why fish prefer shallow water to deep water—the former is warmer. Besides, water is usually warmer in direct sunlight than in the shade. Yet, fish don't have any eyelids and the sun hurts their eyes. The more I understood fish, the more I became effective in finding and catching them.

When I grew up and entered the business world, I remember hearing my first boss say, "We all need to think like sales people." But it didn't completely make sense. My dad never once said, "If you want to catch a fish you need to think like a fisherman." What he said was, "You need to think like a fish." Years later, with great efforts to promote long-term services to people much older and richer than me, I gradually learned what we all need was to think more like customers. It is not an easy job. I will show you how in the following chapters.

China is the native place of tea. Originally(起初), tea (use) as a kind of medicine instead of a drink. Later, as (far) into the features of the ancient Chinese explored  herbs(药草) and made it into atea, they separated it kind of drink and (gradual) it developed into Chinese tea culture.

Records show that the custom of tea drinking,  started from the Western Han Dynasty, already became  fashion for people in a high (society) position during the Northern Wei Dynasty. In the Tang Dynasty it was common (drink) tea. And people tried out even more (approach) to drinking tea. In the Song Dynasty, tea planting and trade were on the increase and the technique of (make) tea was greatly improved. By the Yuan Dynasty, drinking tea had become something very common in everyday life. In the Ming and Qing Dynasties, people drank tea in almost the same way as we do today.

Some people bring out the best in you in a way that you might never have fully realized on your own. My mom was one of those people.

My father died when I was nine months old. While I was growing up, we lived a very hard life. We had little money, but my mom gave me a lot of love. Each night, she sat me on her lap(大腿部) and spoke the words that would change my life, "Kemmons, you are certain to be a great man and you can do anything in life if you work hard enough to get it."

At fourteen, I was hit by a car and the doctors said I would never walk again. Every day, my mom spoke to me in her gentle, loving voice, telling me that no matter what those doctors said, I could walk again if I wanted to. She drove that message so deep into my heart that I finally believed her. A year later, I returned to school—walking on my own!

When the Great Depression(大萧条) hit, my mom lost her job. Then I left school to support both of us. At that moment, I was determined never to be poor again.

Over the years, I experienced various levels of business success. But the real turning point occurred on a vacation I took with my wife and five kids in 1951.I was dissatisfied with the second-class hotels available for families and was angry that they charged an extra $2 for each child. That was too expensive for the average American family. I told my wife that I was going to open a motel(汽车旅馆) for families that would never charge extra for children. There were plenty of doubters at that time.

Not surprisingly, Mom was one of my strongest supporters. She worked behind the desk and even designed the room style. As in any business, we experienced a lot of challenges. But with my mom's words deeply rooted in my soul, I never doubted we would succeed. Fifteen years later, we had the largest hotel system in the world—Holiday Inn. In 1979 my company had 1,759 inns(小旅馆) in more than fifty countries with an income of $1 billion a year.

You may not have started life in the best situations. But if you can find a task in life worth working for and believe in yourself, nothing will stop you.
