Australia has promised to introduce the most comprehensive （全面的） carbon trading program outside Europe in 2010. The government in Canberra plans to cut greenhouse gas emissions (排放) by at least five percent by 2020, but it could make bigger reductions if other countries agree to tougher targets.

    The Australian government warns that without tough environmental measures the country could lose key industries and jobs. Climate Change Minister Penny Wong says the economy is under threat and decisive action is needed.

    Central to the government's climate change plan is a carbon emissions trading program that will be introduced within two years. It would involve one thousand of the nation's biggest companies and would cover about three-quarters of Australia's greenhouse gas emissions.

    Many scientists believe that greenhouse gases, such as carbon dioxide and methane, contribute to global warming. Many of them are released by burning fuels such as coal and oil.

    Companies will be required to buy permits for each ton of carbon they emit, although big polluting exporters will receive up to 90 percent of their carbon licenses free.

    Many business leaders want the government to delay the plan because of the current global financial crisis, which is slowing the Australian economy. Peter Anderson from the Australian Chamber of Commerce and Industry says it is irresponsible to bring in a carbon trading plan now.

    Environmentalists, on the other hand, say Prime Minister Kevin Rudd has not properly addressed the threat of climate change. Activists had sought a minimum emissions cut of 25 percent.

    Instead, the Rudd government aims to cuts carbon emissions by at least five percent of 2000 levels by 2020. That amount could rise to 15 percent, if future global agreements set such a target.

    Ray Nias of the environmental group WWF says Australia will pay the price for low targets. “This is a deeply, deeply disappointing target,” Nias said. “It commits Australia to long-term climate change. It will make Australia's ability to negotiate (协商) global agreements very, very difficult. It is much lower than even we had imagined.”

    Australia has one of the highest per-person greenhouse emissions rates in the world because of its reliance on coal for electricity.

    Some scientists warn that the vast, dry Australian continent, which has been suffering a series of droughts in recent years, could be one of the region's hardest hit by global warming.

    Why we cry with happiness show: Responding with a negative reaction helps us deal with extreme joy. If you cry with happiness at weddings, you are responding to a happy experience with a negative reaction. The researchers believe the unusual reaction may help renew emotional balance in us and keep extreme emotions under control. The findings make it clear how people express and control their emotions, which could help improve their understanding of people's mental(精神的) health.

    Dr Oriana Aragon set out to explore the phrase “tears of joy”, which she said never made sense to her. But after studying a series of incongruous(不和谐的) expressions, she now understands better why people cry when they are happy. “People may be renewing emotional balance with these expressions,” she explained. “They seem to take place when people are struck by strong positive emotions. People, who do this, seem to recover better from those strong emotions.”

    The report show various examples of responding to a positive experience with a negative emotion, such as, a crying wife seeing the husband returning from war again, and teenage girls screaming at a Justin Bieber concert. Examples also include a baseball player who hits a home run, only to be slapped(拍) on the back by teammates, as well as when people cannot help kissing babies' faces who they consider lovely.

    Dr Aragon and her team discovered that people, who expressed negative reactions to positive news, were able to moderate(缓和) strong emotions more quickly. There is also some evidence that strong negative feelings may provoke positive expressions. For example, nervous laughter often happens when people are faced with a hard situation. We've seen people smiling during times of extreme sadness.

    “The findings affect our knowledge of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together,” Dr Aragon said.

    On Wednesday, January 13th, I performed on stage for the first time. As someone who takes part in so many activities, it's extremely difficult to find the time to be a part of any production. For me, it was a once-in-a-lifetime opportunity to try acting through the Senior Play Project.

    Auditions (试镜)came first. They weren't particularly difficult, more to see who may be a better fit tor certain roles. We were told our roles in the various plays, and started to work immediately.

    I was unsure of how I was as an actor, and I had to learn a lot fast: actions, my place in the story, my reactions, and countless other small details... As I began to improve as an actor, I was able to understand my characters better.

    My first character is a man named Roger who is a senior advisor to a presidential candidate in a play called "The Spot." He's a short-tempered guy who says what he wants and takes what he wants to assist his candidate in today's tough political races. He's on the set of The Spot, an advertisement for the candidate, to make sure everything runs smoothly and that any problems are dealt with quickly and efficiently.

    While I had really interesting characters, and the plays were funny and such a great experience to act in, I really love the Senior Play Project for the people. I worked with 12 other seniors who not only loved what they were doing, but offered help and advice throughout my entire learning process.

    Between the lights, sounds, costume and makeup, and plenty more, theatre is a team sport just like basketball or baseball. There are no small parts; there is no one who isn't needed. I've learned to appreciate live theatre, and the effort that every person in the show, both onstage and offstage, puts into it.

    When I was a boy, my parents and I traveled from New York City to the Pennsylvania countryside for a weeklong taste of rural life. We stayed in a guesthouse on a farm, joining the daily routines and eating meals with the farmer and his family. We got up early to see the cows as they were milked. I even tried my hand at milking one, and then joined the farmer as he released the cows into the field afterward.

    Decades later I still have vivid memories of that trip which made me realize the value of a vacation, of seeing new things, meeting new people and sharing memorable experiences with family members. To this day, I still consider that family trip when I plan to take time off with my wife and kids. Vacations are a time for resting and connecting. As a bank manager, I spend much of my workday encouraging my customers to save their money. One of the reasons I give is that we should all have enough for a family vacation every year. In our busy lives, family is what we should be saving our money and time for.

    For my family, our vacation starts when we begin planning the trip. We talk about destinations and our budget (预算) ahead of time. Among the things we discuss: Can we save money by renting a house instead of spending six nights in a hotel? Would it be better to buy groceries and cook for ourselves rather than eat out every night? Involving (使参与) the kids in planning the vacation makes sure that they have a great vacation too. I prefer to visit historical sites and museums while they love to fish and swim. So I build in some relaxation time for us all so that the vacation can work for everyone.

    Each year, setting aside vacation time to spend together is especially important to us. A relaxing environment opens the doors to all kinds of conversations—deep, silly or meaningful. There's no pleasure from the usual everyday tasks. What matters is that everyone is having a great time.

    I grew up on a farm outside Port Clinton, Ohio. I was the youngest son, with four brothers and four sisters, plus a girl my relatives took in when she was in sixth grade and was raised along with us.

    By the late 60s, most of us were married and had families of our own. One day, while we were visiting my parents in late summer or early fall, Dad mentioned he'd always wanted a Crimson King maple tree for the yard. Mom agreed that they were pretty.

    Like many parents, mine were hard to shop for, so I figured this was a great opportunity to get them something they'd appreciate. I checked the price at work and decided it was a bit more than I could afford but all of my brothers and sisters agreed to help.

    In northern Ohio, people don't plant maple trees at Christmas, so we decided to surprise Mom and Dad with a special Christmas in October before the ground froze. We asked my aunt if she'd help us with the trick, and she called my parents in advance to say she was coming for a Sunday visit. Then my sisters and sisters-in-law went into action, planning a big holiday turkey dinner.

    On the chosen Sunday, we all met at my house and loaded the trees in a pickup truck. I dressed up as Santa Claus, though at the time I weighed about 140, so all the padding(填料) in the world couldn't make me look like St. Nick. Then off we went, nine or ten cars loaded with people and food, plus the pickup truck.

    When the truck arrived at my parents' house, Dad came out of the back door, convinced something was wrong. He and Mom were amazed when we told them why we were there.

    When Christmas rolled around, of course, we couldn't go to our parents' house empty-handed, so Mom and Dad got double presents that year. Almost half a century later, I still drive by the old farm and smile when I see those big, handsome trees.
