In Britain, it's bottoms up from the week before Christmas till the last firework explodes in the sky announcing the new year. The last Friday before Christmas, popularly known as ‘Mad Friday', is one of the busiest periods for the country's pubs and clubs.

    But it's not just the bars that get busy. Ambulances and A&E departments around Britain get packed out too. Head injuries, cuts, falls…it's easy to end up hurting yourself or others when self-control disappear and your head is spinning due to alcohol revelers have been warned by the health authorities about the dangers of deadly drinking but drinking crazily seems to be part of the festivities for some.

    The charity Alcohol Concern is running a campaign of restriction by encouraging people to have a dry January.

    Jackie Ballard, the charity's Chief Executive, believes the campaign has been successful in recent years. She says, “More than two-thirds of people even six months later are drinking at reduced levels having had amonth off drink. But also a study has shown the impact it has on people's health reducing their blood pressure and blood sugar levels.”

    The study by the University of Sussex followed up nearly 900 participants in Alcohol Concern's Dry January campaign and found out that 72％ of them hadkept harmful drinking sessions down and 4％ were still not drinking.

    Moderation (适度) seems to bethe key to everything. The official recommendation for women is not to regularly drink more than 2 to 3 units of alcohol a day. The limit for men is 3to 4 units of alcohol — no more than a pint of 5.2％ ABV lager, beer or cider.

    BEIJING — The launch of a new manned space mission brings China closer to the establishment of a permanent space station, international experts say.

    Chinese taikonauts, Jing Haipeng, 50, and Chen Dong, 37, were blasted off into space onboard Shenzhou-11 at 7:30 am Monday and will spend 30 days in the Chinese space laboratory Tiangong-2.The launch marks a key step toward China's plan to eventually operate a permanent space station. The successful launch of the Shenzhou-11 spacecraft is another step forward to put China among leading players in space technology, said Alexander Zheleznyakov, a Russian expert on history of space flights. China's experimental space lab will help provide solutions for spacecraft of different functions to approach and anchor, and for a long-term operation of life support system, said Zheleznyakov. Shenzhou-11 is scheduled to anchor on Wednesday with Tiangong-2, which is part of China's plan to build a permanent space station by 2022.

    China can now test technologies for cargo spacecraft anchoring, life support system operation and water recycling to ensure a long-term continuous operation of its space station in the future with less dependence on renewal from the Earth, he said. If all goes well, China will launch the unpiloted Tianzhou-1 cargo ship next spring to autonomously tie up with Tiangong-2. Tianzhou-1 will be capable of automatically transferring rocket fuels, a vital requirement for space station grouping and maintenance, according to a report by Columbia Broadcasting System (CBS).

    "That will further their anchoring abilities needed for the larger space station," Johnson Freese was quoted." Tiangong-2 is supposed to be able to stay in orbit for two years or longer, so that's taking them (Chinese) really close to 2019 or so. I think this will be their last big technology test phase before going to their large space station," said Freese.

    My parents were in a huge argument, and I was really upset about it. I didn't know who I should talk with about how I was feeling. So I asked Mom to allow me to stay the night at my best friend's house. Though I knew I wouldn't tell her about my parents' situation, I was looking forward to getting out of the house. I was in the middle of packing up my things when suddenly the power went out in the neighborhood. Mom came to tell me that I should stay with my grandpa until the power came back on.

    I was really disappointed because I felt that we did not have much to talk about. But I knew he would be frightened alone in the dark. I went to his room and told him that I'd stay with him until the power was restored. He was quite happy and said, “Great opportunity.”

    “What is it?” I asked.

    “To talk, you and I” he said. “To hold a private little meeting about what we're going to do with your mom and dad, and what we're going to do with ourselves now that we're in the situation we are in.”

    “But we can't do anything about it. Grandpa,” I said, surprised that here was someone with whom I could share my feelings and someone who was in the same “boat” as I was.

    And that's how the most unbelievable friendship between my grandfather and me started. Sitting in the dark, we talked about our feelings and fears of life — from how fast things change to how they sometimes don't change fast enough. That night, because the power went out, I found a new friend, with whom I could safely talk about all my fears and pains, whatever they may be. Suddenly, the lights all came back on. “Well,” he said, “I guess that means you'll want to go now. I really like our talk. I hope the power will go out every few nights!”

    Feeling sad is an important part of human nature.

    Jerome Wakefield, a professor at New York University, mentions that feeling down after your heart is broken is normal and may even be beneficial. Recently, Wakefield's students have been coming up to him because their parents are pressuring them to get help for their sadness; often the kids want no part of it. Rather than “listen to medicine,” they want to listen to their hearts. He believes these students' reaction represents an important part of human nature.

    Professor Diener, who has studied happiness for a quarter century, finds that the Scots and many other peoples like being sad, and don't appreciate being told they should be happier. “They say too much happiness might not be such a good thing, no matter where it comes from,” says Diener. He believes it's wrong for the “happiness industry” to send the message that not only can we all be happier, but we have a duty to be so. He argues that what is considered normal sadness is something we shouldn't avoid.

    Eric Wilson, a professor at Wake Forest University, made every effort to smooth out his habitual frown and wear a sunny smile, since a happy expression can lead to happy feelings. He even tried to be enthusiastic. When neither of these made him happy, he concluded that such a happiness movement was no good for him at all. Americans, love for happiness, he writes, creates an environment where sadness is not valued.

    These researchers believe the problem of continuous, extreme happiness should not be surprising, since negative emotions developed for a reason. Fear warns us against the presence of danger, for instance. Sadness, too, seems to be part of our DNA: monkeys, dogs and elephants all display something that looks like sadness. Being “up” all the time can cause you to play down very real threats.

    They believe that only by experiencing sadness can we experience the fullness of the human condition. Their studies show that when you are in a negative frame of mind, you become more logical and more creative. Abraham Lincoln was not limited by his dark moods, and Beethoven composed his later works in a sad state. Vincent van Gogh, Emily Dickinson and other artistic giants saw the world through a glass darkly.

    People who are somewhat unhappy are more motivated to improve both their own lot and the lot of their community. In contrast, people at the top of the happiness charts feel no such urgency. “If you're totally satisfied with your life,” says Diener, “you don't feel like working for change. Be careful when people tell you that you should be happier.”

    The Board Meeting had come to an end. Bob started to stand up and pushed the table, spilling his coffee over his notes. “How embarrassing! I am getting so clumsy in my old age.”

    Everyone had a good laugh, and soon we were all telling stories of our most embarrassing moments. It came around to Frank who sat quietly listening to the others.

    Frank began,“My Dad was a fisherman. He worked hard and would stay out until he caught enough to feed the family. Not just enough for our family, but also for his Mom and Dad and the other kids that were still at home.”

    Frank's voice dropped a bit. “When the weather was bad he would drive me to school. He would pull right up in front, and it seemed like everybody would be standing around and watching. Then he would lean over and give me a big kiss on the cheek and tell me to be a good boy. It was so embarrassing for me. Here I was twelve years old, and my Dad would lean over and kiss me good-bye!”

    He paused and then went on, “I remember the day I thought I was too old for a good-bye kiss. When we got to the school, he had his usual big smile. He started to lean toward me, but I put my hand up and said, 'No, Dad.' It was the first time I had ever talked to him that way, and he had this surprised look on his face. I said, 'Dad, I'm too old for a good-bye kiss. I'm too old for any kind of kiss.' My Dad looked at me for the longest time, and his eyes started to tear. I had never seen him cry. He turned. 'You're right,' he said. 'You are a big boy ... a man. I won't kiss you anymore.'”

    For the moment, the tears began to well up in Frank's eyes. “It wasn't long after that when my Dad went to sea and never came back.”

    I looked at Frank and saw that tears were running down his cheeks. Frank spoke again.“Guys, you don't know what I would give to have my dad give me just one more kiss on the cheek.”

    People in the United States honor their parents with two special days： Mother's Day, on the second Sunday in May, and Father's Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.

    These two special days are celebrated in many different ways. On Mother's Day people wear carnations(康乃馨). A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery(墓地).On these days, families get together at home, as well as in restaurants. They often have outdoor barbecues for Father's Day. These are days of fun and good feelings and memories.

    Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries(烘焙店), telephone companies, and other stores do a lot of business during these holidays.
