Last year I ruined my summer vacation by bringing along a modern convenience that was too convenient for my own good: the iPad. Instead of looking at nature, I checked my email. Instead of paddling a small boat, I followed my Twitter feed (推特简讯). Instead of reading great novels, I stuck to reading four newspapers each morning. I was behaving as if I were still in the office. My body was on vacation but my head wasn't.

    So this year I made up my mind to try something different: withdrawal (退出) from the Internet. I knew it wouldn't be easy, since I'm bad at self-control. But I was determined. I started by giving the iPad to my wife.

    The cellphone signal at our house was worse than in the past, making my attempts at cheating an experience in frustration (沮丧). I was trapped, forced to go through with my plan. Largely cut off from e-mail, Twitter and my favorite newspaper websites, I had few ways to connect to the world except for radio and how much radio can one listen to, really? I had to do what I had planned to all along: read books.

    This experience has had a happy ending. With determination and the strong support of my wife, I won in my vacation struggle against the Internet, realizing finally that it was I, not the iPad, that was the problem.I knew I had won when we passed a Starbucks and my wife asked if I wanted to stop to use the Wi-Fi. “ I don't need it,” I said.  

    However, as we return to post -vacation life, a harder test begins: Can I continue when I'm back at work? There are times when the need to know what's being said right now is great. And I have no intention of giving up my convenience completely. But I hope to resist the temptation (诱惑) to check my e-mail every five minutes, which leads to checking my Twitter feed and a website or two.

    I think a vacation is supposed to help you reset your brain to become more productive. Here I hope this one worked.

    When most of us look at our hands, we might notice that we need to clean, or stop biting our fingernails, and that's about it. But if you ask a doctor, he can see a whole lot more. Everything from poor diet and stress to serious kidney (肾) problems can be revealed by a glance at your fingernails.

    There are about 30 different nail signs that can be associated with medical issues, though may indicate more than one problem, according to Dr. Amy Derick, a clinical instructor of dermatology at Northwestern University.

    Here are five of the things a doctor can tell about your health based on your fingernails.

    ⒈People who aren't eating well and lack vitamin or dietary may have thinner than normal nails, which are more likely to break.

    ⒉Horizontal lines are associated with serious physical stress. They frequently occur in people who have gone through chemotherapy(化疗).They can also occur after some illnesses, injuries, or with severe malnourishment(营养不良).Interestingly, there may be an altitude connection too. They've also been found in people who dove 1,000 feet and others who participated in an Everest exploration.

    ⒊Vertical lines, however, are generally not such a big deal. Some people are more genetically prone to them than others, but they're commonly associated with aging.

    ⒋When people lack iron, their nails can turn spoon-like. Instead of curving down and covering the finger normally, they'll start to rise up on the sides and front, like the part of a spoon that holds liquid.

    ⒌Kidney and liver problems can create “half-and-half nails”, where one part of the nail is white and the other part dark or pink, according to Derick.

    Doctors note that because disease diagnosis is complex and some symptoms can be associated with different diseases, you should always see a medical professional if you are concerned about something you notice.

    Sandra Cisneros was born in Chicago in 1954 to a Mexican American family. As the only girl in a family of seven children, she often felt like she had "seven fathers," because her six brothers, as well as her father, tried to control her. Feeling shy and unimportant, she retreated (躲避) into books. Despite her love of reading, she did not do well in elementary school because she was too shy to participate.

    In high school, with the encouragement of one particular teacher, Cisneros improved her grades and worked for the school literary magazine. Her father encouraged her to go to college because he thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the university's Writers' Workshop, however, she felt lonely－a Mexican American from a poor neighborhood among students from wealthy families. The feeling of being so different helped Cisneros find her "creative voice".

    "It was not until this moment when I considered myself truly different that my writing acquired a voice. I knew I was a Mexican woman, but I didn't think it had anything to do with why I felt so much imbalance in my life, but it had everything to do with it! That's when I decided I would write about something my classmates couldn't write about."

    Cisneros published her first work, The House on Mango Street, when she was twenty-nine. The book talks about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been used in classes from high school to graduate school level. Since then, Cisneros has published several books of poetry, a children's book, and a short-story collection.

    It is reported that a record-breaking high-speed rail will connect Inner Mongolia in the north to Hainan in the south. According to the Shaanxi Development and Reform Commission, the proposed line will operate at a speed of 350 kilometers per hour(217 mph).

    Beginning in Inner Mongolia's Baotou city and running through southern Shaanxi, Hubei, Hunan, Guangxi and Guangdong, its final stop would be in Haikou city on Hainan Island, China's southernmost province.

    Though the exact length of the proposed route has not been released, it will likely become the world's longest high-speed rail line as the journey by road between Baotou and Haikou is approximately 3, 000 kilometers(1, 864 miles) long. Currently, the world's longest high-speed rail line is almost 2, 300 kilometers long (1, 429 miles), running from Beijing to Guangzhou.

    The proposed rail is part of China's aim to create another "Silk Road of the 21st Century" and improve the country's transportation network while driving land development and urbanization(城市化) in some provincial areas.

    Many of the provinces through which the high-speed trains will travel are near major bodies of water, such as the Yellow River in Inner Mongolia and Shaanxi province, the Yangtzi River in Hubei and the South China Sea, where the line would end. It will also take passengers to popular tourist attractions including Zhangjiajie, Xi'an, Guilin and minority areas in western Hunan and Hubei.

    "The country is now shifting its focus and investing in the western regions and economically underdeveloped areas, making up for China's long debt to these areas, " Tan yuzhi, professor of the School of Economics and Management at Hubei University for Nationalities, told local media. " The project will significantly narrow regional disparities(差异) and solve minority issues."

    However, Deng Hongbing, director of China University of Geosciences' Center for Regional Economic and Investment Center, said that if the north-to-south railway is to go ahead, there needs to be a sound ecological program in place to ensure the protection of these underdeveloped and ecologically sensitive areas.

Writing out the same word again and again may bring back bad memories for some, but handwriting can boost connectivity across brain regions, some of which are involved in learning and memory, a new study shows. 

In the study, psychologists Audrey and Ruud, both at the Norwegian University of Science and Technology, stuck electrodes（电极）on the participants' heads. They asked the participants to type out or handwrite with a digital pen words that appeared on a computer screen. Sensors in a cap recorded electrical brain activity. Then the psychologists looked for when two brain areas are active with the same frequency of electrical waves at the same time. This result can reveal the connectivity among different regions across the brain. 

With handwriting, the researchers saw increased activity, specifically in low frequency bands, not only in the expected motor areas but also in others associated with learning. These low frequency bands have previously been shown to support memory processes. When the team compared the two tasks, they realized that handwriting—but not typing—increased the connectivity across parietal（顶叶）brain regions, which are involved in sensory and motor processing, and central regions, many of which are involved in memory. "Even when the movements are very similar, the activation seems much, much higher in handwriting," Audrey says. "It shows that there's more involvement of these brain regions when you're handwriting, which might give you some specific advantages."

These findings suggest that there are distinct processes of brain activation happening while a person types or writes. This boost of stimulation of handwriting facilitates learning because these particular waves between these areas are involved in memory formation and encoding（编码）. 

And although handwriting may help with learning processes, typing is often easier, faster and more practical. "Students and teachers alike should therefore consider the task at hand to decide to handwrite or type, "Audrey says. Despite the need for more studies to determine the best learning strategy, experts say that handwriting shouldn't be left behind in the digital age. "Schools need to bring in more writing into curriculum design," Ruud says.
