Over the last week, a "poisonous kale（甘蓝菜）" theory has been going widespread after an article warned that the vegetable was associated with a variety of medical conditions. It's time to separate fear from fact on the health benefits of kale.

    As a member of the cabbage family, kale is low in calories and rich in nutrients and minerals, especially vitamin A,C and K. Consumed for thousands of years, it's been a health plus for millions of eaters throughout the world.

    However, numerous web articles have reported on some evidence offered by a medicine researcher. The researcher found that thallium（铊）was detected in a few people who were heavy consumers of kale. Thallium is a heavy metal often found in trace amounts（微量）in soil and minerals. His conclusion was that these medical conditions were connected to the impact that trace amounts of thallium detected in some kale samples had on the body.

    I don't think the conclusion is based on a strict scientific basis. It's essential to point out that the original report was in a web magazine, not a scientific journal which is subject to peer review by other scientists. A scientific review includes a careful evaluation of how the findings and conclusions were made. Certain factors are critical before an evidence-based conclusion can be made, such as: how many people were in a study; how well controlled were other factors; how much kale was consumed and for how long; how much thallium was in the kale.

    It is a fact that kale and other vegetables can absorb thallium from the soil. But the ability for a plant to absorb traces of a chemical does not automatically make it harmful to your health. And even finding measurable amounts of thallium in someone's body doesn't imply that the thallium is causing an ill health effect, according to the CDC.

    But we can still learn a lesson from this. Plants grow in soil. Growers must continue to be careful in monitoring the quality of their soil. And what about consumers? Eat your kale—and include lots of other colorful fruits and vegetables. As with all things in nature, variety is key for good health.

    Do you have cold feet in winter? But now if you wear a pair of Ugg boots, you won't be troubled by that.

    UGG means Australian Sheepskin Boots. UGG boots became popular among shearers(剪羊毛的人）in the 1920s. The shearers sheared the sheep and grabbed a bit of dead sheep, wrapped it around their feet and called them “Ugly Boots”. Good old Australian slang shortened Shearers Ugly Boots to UGG boots. Thus UGG Boots date back as far as the 1920s in Australia.

    Ugg boots became so popular because of the amazing amount of comfort they bring to the feel. The sheepskin is made incredibly soft so the boots are warm and comfortable. Ugg boots fed more like socks than shoes, yet they are tough enough for outdoor wear. The unique, wool fool-beds lake the shape of the natural edge of each wearer's feet, creating personalized arch (弓形) supports.

    Our ugg boots are handmade with Australian sheepskin of the highest quality by our factory of Ugg Original Pty Ltd.

    We can also wear ugg boots in cold weather or summer. In cold weather, the thick wool of ugg boots provides a preventing layer of warmth by trapping your body heat. In the heat of summer, the natural fibres of the wool will actually cool your feet by absorbing sweat. Ugg boots are made to be worn barefoot to maximize the cushioning and warmth provided by the sheepskin.

    At 17, Mark Merwitzer might be Florida's youngest lobbyist (游说者). The Miami high school junior appeals to authorities to keep drivers from texting behind the wheel.

    Over the past year, the teen has met with county officials and state legislators (立法者)to argue that the police should be able to pull drivers over just for using their phones. Efforts in past years have struggled to advance, but recently, the bill got full support from the Senate Transportation Committee (参议院交通委员会).

    Like many US people, Merwitzer has seen countless drivers texting behind the wheel. But last spring, while he was riding in the passenger seat of a vehicle, he saw drivers using smartphones in almost every car. A few drivers even appeared to lose control of their cars as they sped along. It dawned on (突然想到) Merwitzer that no one was doing anything to fix the problem.

    We need to teach drivers how to properly and safely use technology behind the wheel which is not using it at all,” said Merwitzer.

    For the 17-year-old teenager, advocating a new state law has been a crazy experience.

    In order to carry out his plan，he put his focus on drumming up (争取)local support by starting an online petition (请愿)and speaking to village councils,

    Merwitzer said the first time he spoke at a council meeting “was a complete stutter fest (口吃表演)，” but he quickly adapted to it.

    “It really creates some standards that help everybody realize the importance of keeping their eyes on the road,” said Miami-Dade Commissioner (专员)Levine Cava.

The commissioner has been so impressed with Merwitzer's understanding of the political process. “He really learned very quickly how to be an effective citizen lobbyist,” she said.

    So far, opposition to the bill has come mainly from police departments. Some are worried about the possibility of lawsuits (诉讼)if officers are accused of racially profiling (按种族形象定性) drivers when accusing them of texting and driving，Merwitzer said. The bill also has critics in the House, where lawmakers have yet to make plans for a hearing.

    Merwitzer said he would one day like to be a state legislator, but in the meantime he has a few short-term goals, like finishing school and going to college. Once the legislative session (期间) is over, Merwitzer plans to turn his attention to another local problem: public transportation. “I'd like to focus on that，” Merwitzer said. “It seems like it's a giant mess,”

    When men get together, they seldom talk about their feelings or inner thoughts. However, they talk about a lot, like their newest computer, how to repair their car, or even business.

    Talk might move to the best place to find fish or women, jump to computer games, then continue to the sport of the season. They also like to tell jokes each other and spend a fair amount of time playing one-up and boasting (吹牛). Men seldom call each other to chat.

    When man meets woman, he usually wants to make a good impression. Many single men try hard to carry on amusing, fun, and pleasant conversations. They use conversation to discover her interests and feelings in order to learn how to be attractive to her.

    Some men, either out of nervousness or ignorance, spend most of the time talking about themselves, often appearing to brag about their achievements or talk endlessly about their problems or work. Even the quietest man talks to his woman when love is new.

    When women get together, they talk about feelings and relationships, their work and their family. They enjoy talking but also want the give and take of talk, then listen. Women often call each other to chat. Conversation is an important part of most women's 1ives.

    As relationships progress, however, many a man turns on the television and forgets how to talk. This raises anger and cry from his woman partner who says, “You never talk to me anymore.” Some men start talking. Many, however, mainly discuss their own achievements and problems.

    When the woman starts talking about her favorite subjects: feelings, family, relationships, friends and her work, many men lose interest or bring the conversation back to themselves. Pretty soon, the man is back to staring at the television each night, wondering where his relationship has gone. The woman is talking to her friends, mom, sister, or neighbor, often about that very relationship and how she is hurting.

    Mr. Brown was a writer. He wrote many books, and he thought they were quite good. He lived in the city. One morning, he went to a small town near the city to visit a friend. He went there by bus. When he got to the town, he saw a bookshop not far from the bus stop. As it was early, he decided to go in and have a look. There were many books in the shop. He was very happy that all the books in the shop were written by him. "Where are other writer's books?" he asked the man in the shop. The man looked up at him and answered. "Oh, they are all sold out."

    Many studies have hinted(暗示) that alcohol, in moderation, can do a heart good. But new research suggests that moderate drinkers are no more likely than non­drinkers to have clear arteries(动脉).

    The scientists looked at almost 2,000 patients who underwent CT test. Overall, there was no association between people's drinking habits and their heart diseases. Researchers said an advantage of the new study is that it used objective measurements.

    “No prior studies have assessed the relationship between alcohol consumption and the presence of heart disease,” said lead researcher Dr Julia Karady. "We could not find any relation between the presence of heart disease and alcohol consumption," Karady said. At the same time, she added, there was no evidence that heavier drinking raised the risk of heart disease.

    However, groups like the American Heart Association(AHA) warn against excessive drinking, because it can raise blood pressure and contribute to heart failure and other problems.

    In general, "moderate" is defined as no more than one glass of alcohol a day for women, and no more than two a day for men. But those studies do not prove that alcohol, itself, protects the heart—in large part because alcohol also carries risks.
