Greece's finance minister says his country's financial situation is “terribly urgent” and the crisis could come to a head in a couple of weeks. Yanis Varoufakis gave the warning after eurozone finance ministers met in Brussels to discuss the final €7.2bn tranche(援助资金) of Greece's €240bn EU/IMF bailout(紧急援助).

    Ministers said Greece had made “progress” but more work was needed.

The Greek government is struggling to meet its payment obligations（责任）.Earlier, Greece began the transfer of €750m (£544m, $834m) in debt interest to the International Monetary Fund - a day ahead of a payment deadline.

    “The liquidity（资产流动性） issue is a terribly urgent issue. It's common knowledge, let's not beat around the bush,” Mr Varoufakis told reporters in Brussels. “From the perspective of timing, we are talking about the next couple of weeks.”

    Greece has until the end of June to reach a reform deal with its international creditors. Its finances are running so low that it has had to ask public bodies for help. The crisis has raised the prospect that Greece might default（违约） on its debts and leave the euro.

    In a statement, the eurozone finance ministers said they “welcomed the progress that has been achieved so far” in the negotiations,” but added: “We acknowledged that more time and effort are needed to bridge the gaps on the remaining open issues.” Eurogroup chairman Jeroen Dijsselbloem said there had to be a full deal on the bailout（紧急财务援助） before Greece received any further payments. “There are time constraints(限制；约束) and liquidity constraints and hopefully we will reach an agreement before time runs out and before money runs out.” he said.

    There had been fears that Greece would default on its IMF debt repayment due on Tuesday. However, a Greek finance ministry official was quoted as saying that the order for repayment had been executed（实施） on Monday. Almost €1bn has been handed over to the IMF in interest payments since the start of May.

    It is unclear how the government came up with the funds, but the mayor of Greece's second city Thessaloniki revealed last week that he had handed over cash reserves in response to an appeal for money.

    Almost everyone wants to be happy, but not all know how to find happiness. Money and success alone do not bring lasting happiness. Aristotle, a Greek thinker, said, “Happiness depends upon ourselves.” In other words, we make our own happiness. Here are a few suggestions to help you be happier.

    The first secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future that we fail to enjoy the present, for example, getting into college or getting a good job. You should enjoy life's simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have several close friends often live happier and healthier lives.

    Another secret to living a happy life is to be active, and have hobbies where you forget your problems and time. Many people experience dancing, or playing a sport, such as swimming. You can forget about your problems and only think about the activity.

    Finally, many people find happiness in helping others. Studies show that people feel good when they spend their time helping others. If you want to feel happier, do good things for someone. You can help a friend with his or her studies, go shopping to buy food for an elderly person, or simply help out around the house by washing the dishes.

    If you see a group of people dancing and singing on the street or in the railway station, you don't need to feel surprised. They are a flash mob(快闪族). Who are they Are they mobs? Don't be confused by their name. Actually, a flash mob is a group of people who gather suddenly in a public place, do something unusual for a brief period of time, and then quickly disappear.

    They are usually organized with the help of the Internet or other digital communications networks. The messages may be sent to friends, who send to more people. At a predetermined time, they gather and perform some activities such as exchanging books, coming together to look at the sky, waving their hands and yelling something at the top of their voice for 30 seconds. Then, they quickly disappear before the police can arrive Using mobile phones, the flash mob can change its place if the first one has been cancelled for any reason.

    Bill Wasik, senior editor of Hamper's Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob gathered on June 3, 2003. Wasik claimed that he created the flash mob as a social experiment designed to laugh at fashion seekers and stress the cultural atmosphere of wanting to be an insider or part of "the next big thing”.

    Flash mob gatherings can sometimes shock people. Such an activity might seem amusing and magical, but it also might frighten people who are not aware of what is taking place. Undoubtedly, flash mob can serve as good political tools and have great potential, such as using flash mob to advertise a product.

    The flash mob is now becoming more and more popular. People use it to do many things. Flash mobs give people from all walks of life an opportunity to come together to create a memory.

    Based on new analysis, we are rapidly approaching major climate change and the effects on society and the environment could be quite severe. Geographers predict that within the next eighty years, current world climate zones could shift and some could completely disappear. Polar regions will get colder while tropical regions will get even hotter, forcing animals to migrate  (迁徙) north.

    Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes will not only increase but may also become more intense. If the changes come too quickly, animal and plant species may not be able to adapt fast enough and could disappear.

    According to Science Daily, a new study predicts that by the year 2100, many of today's familiar climates will be replaced by climates unknown in today's world. It is urgent that we reduce the risks of these far-reaching consequences for the whole world. The planet itself has been showing signs of change. In 2004, a serious tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands died in China because of another severe earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.

    Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously thought. At this point, it doesn't matter what is causing it, but rather, what can be done about it. What's more, our world is getting more and more unstable every year. There is war and threat of war everywhere. Natural disasters are becoming more frequent and serious.

    However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connection between this. No one knows anything for sure at this point because there is simply not enough data.

    If all the food that's thrown away in three American cities could be saved, it would provide 68 million meals for people who don't have enough to eat, according to a recent study.

    The researchers found that, in the cities they surveyed（调查）, more than a kilogram of edible food per person is wasted each week. Edible food is food you can eat. It doesn't include things like apple cores（果核）, egg shells, or bones from meat. Fruits and vegetables were the most common edible foods found in the dustbin, followed by food leftover from meals. Eggs, bread and milk were also commonly thrown out.

    The people taking part in the survey gave several reasons for throwing edible food away. Most said the food went off. Some said they weren't interested in eating leftovers. A few said the food had passed the “Best Before” date printed on the label（标签）. When food is wasted—by families, restaurants or grocery stores—we are also wasting all of the resources that go into producing that food. That means we are wasting water, land, energy and labour, as well as the fuel needed to transport food.

    A lot of food is wasted before it even reaches the grocery store（食品杂货商）. Some food is damaged while it is being transported from the farm to the stores. Fruits and vegetables that don't look attractive enough don't even get put onto the shelves because most people won't buy them. Grocery stores, restaurants and hospitals also waste a large amount of food. The researchers suggest that grocery stores should donate any food that is still okay to eat to homeless shelters, instead of throwing it away. Prepared meals from hospitals or restaurants could also be donated to shelters.
