Every man wants his son to be somewhat of a clone, not in features but in footsteps. As he grows you also age, and your ambitions become more unachievable. You begin to realize that your boy, in your footsteps, could probably accomplish what you hoped for. But footsteps can be muddied and they can go off in different directions.

    My son Jody has hated school since day one in kindergarten. Science projects waited until the last moment. Book reports weren't written until the final threat.

    I've been a newspaperman all my adult life. My daughter is a university graduate working toward her master's degree in English. But Jody? When he entered the tenth grade he became a “vo-tech” student(技校学生). They're called “motorheads” by the rest of the student body.

    When a secretary in my office first called him “motorhead”, I was shocked. “Hey, he's a good kid,” I wanted to say. “And smart, really.”

    I learned later that motorheads are, indeed, different. They usually have dirty hands and wear dirty work clothes. And they don't often make school honor rolls(光荣榜).

    But being the parent of a motorhead is itself an experience in education. We who labor in clean shirts in offices don't have the abilities that motorheads have. I began to learn this when I had my car crashed. The cost to repair it was estimated at $800. “Hey, I can fix it,” said Jody. I doubted it, but let him go ahead, for I had nothing to lose.

    My son ,with other motorheads, fixed the car. They got parts from a junkyard, and ability from vo-tech classes. The lost was $25 instead of $800.

    Since that first repair job, a broken air-conditioner, a non-functioning washer and a non-toasting toaster have been fixed. Neighbors and co-workers trust their car repairs to him.

    These kids are happiest when doing repairs. They joke and laugh and are living in their own relaxed world. And their minds are bright despite their dirty hands and clothes.

    I have learned a lot from my motorhead: publishers need printers, engineers need mechanics, and architects need builders. Most important, I have learned that fathers don't need clones in footsteps or anywhere else.

    My son may never make the school honor roll. But he made mine.

    A recent study presents the possibility of “carbon farming” as a less risky alternative to other carbon capture and storage technologies. It suggests that a significant percentage of atmospheric CO₂ could potentially be removed by planting millions of acres of a shrub known as the Barbados nut（麻疯树）, in dry, coastal areas. But other experts doubted whether the Barbados nut would be able to grow well in sandy desert soils and absorb the quantity of carbon their models predict.

    The researchers behind the study say Barbados nut plantations（种植园）could help to reduce the local effects of global warming in desert areas, causing a decrease in average temperature and an increase in rainfall. If a large enough portion of the Earth were blanketed with carbon farms, these local effects could become global, capturing between 17 and 25 metric tons of CO₂ per hectare each year over a 20-year period.

    Carbon farms would not compete with food production if they were concentrated in dry coastal areas. In their analysis, oceanside desalination（海水淡化）plants provide a low-emission irrigation method. The study states that the Barbados nut is uniquely suited to growing in regions unsuitable for other crops .The plant, which produces a non-edible seed that can be used to create biodiesel（生物柴油）, is comfortable growing at temperatures exceeding 100 degrees Fahrenheit. It can also stand up to high levels of pollution in the soil, making waste water another potential source for irrigation.

    The cost of carbon farming is comparable to the costs associated with other carbon capture and storage technologies, the study claims. Wulfmeyer stressed that carbon farming could have “fantastic value for the local people” if international carbon markets pick up, promoting rural development and opening up the possibility of additional agriculture as the soil quality improves around the plantation.

    In an email, Van Noordwijk, a chief science advisor, questioned the growth rate and the atmospheric carbon capture rate assumed by the study's authors, calling the estimated carbon price of the plantations a “considerable underestimate”. “We are talking about a plant with a shrubby growth habit and a long track record of misleading farmers with production potentials that are not being realized,” he said, and “Even with abundant water, the nutrient storage in sandy desert soil is low. He added, “The estimated carbon price of this option already indicates that there are far better opportunities for reducing ongoing emissions from peatland（泥炭地）use and deforestation.”

    Do you like eating processed meat? If you do, think twice now if you want to eat such meat for the sake of your health. Why? It's because eating processed meat can cause cancer, World Health Organization (WHO) experts said last Monday.

    Processed meat is the meat that has been preserved by salting, smoking, drying or canning. Experts from the WHO's International Agency for Research on Cancer (IARC) in Lyon, France studied 800 patients. The experts connected processed meat, such as hot dogs and bacon, with at least three kinds of cancer. A person who eats 50 grams of processed meat per day—about two pieces of bacon—increases his or her risk of bowel(肠) cancer by 18 percent.

    The IARC has included processed meat in its Group 1 list, for which there is “enough evidence” of connection with cancer. Tobacco is also on the Group 1 list.

WHO experts also say red meat, including beef, lamb and pork, is “probably” carcinogenic (致癌的) to humans. Dr. Kurt Strait is with the IARC. He said in a statement that the risk of cancer increases with the amount of meat a person eats. Health experts in some countries advised against eating large amounts of red and processed meat. But those suggestions had been centered on the increased risk of heart disease and obesity.

    However, meat industry groups protest the result of the WHO study. They say that meat is part of a balanced diet. They also say the causes of cancer are broad, and include environment and lifestyle factors.

    The WHO report cites the Global Burden of Disease project, which shows that diets high in processed meat lead to 34,000 cancer deaths per year worldwide.

    Vatican Museums: Vatican City

    The Vatican draws more than five million people each year, and queues can reach four hours during peak season. Christie Hudson, senior communications manager at Expedia，recommends, choosing a skip-the-line tour.“ This not only lets you avoid the ticket counter，but also includes the use of a private partner entrance.” Extra time to visit the Sistine Chapel? Yes!

This will give you entry to the pyramid within a half-hour window. The Louvre is also open until 9:45 p.m. on Wednesdays and Fridays, if you're up for some late-night art visits.

    Learning Chinese could be one of the most important decisions you ever make. Chinese is becoming the language to learn in the 21^st century. With the world's largest population and a rapidly growing middle class, China stands to become the engine of the world's economy in the coming years. This will make learning Chinese very important for people in many industries, or for those of us who wish to visit China or learn from its culture and history.

    There is an ongoing effort to modernize the writing system and standardize the language. An increasing number of people learning Chinese are learning the Mandarin, so unless you absolutely need to learn another dialect (such as Cantonese), be sure you are studying Mandarin.

For native English speakers Chinese is one of the most difficult and most different languages to learn. The vocabulary is wholly unfamiliar and unlike anything we know. In addition, in the Chinese tone system, words are spoken in rising or falling tones, which help to distinguish between them. Furthermore, there is the Chinese writing system— a collection of thousands of individual ideograms (表意文字), or symbols, which represent a word or an idea. These ideograms have no phonetic value—that is to say, we can't tell how the word is pronounced by how it is written. There is a method to present written Chinese in a phonetic script called pinyin. If you are learning Chinese, you'll be working with this pinyin system, but the beauty of the traditional writing system shouldn't be passed up. All these factors make learning Chinese difficult for us. Yet, for a determined learner, there's always a way to overcome it.
