    Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy (星系).The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world. It was captured by the Event Horizon Telescope (EHT).

    The announcement was made in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo. Details have been published today in Astrophysical Journal Letters.

    Prof Heino Falckc, of Radboud University in the Netherlands, who suggested the experiment, told BBC News that the black hole was found in a galaxy called M87. "What we see is larger than the size of our entire Solar System," he said. "It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute monster, the heavyweight champion of black holes in the Universe."

    The image shows an intensely bright "ring of fire", as Prof Falckc describes it, surrounding a perfectly circular dark hole. The bright halo is caused by very heated gas falling into the hole. The light is brighter than all the billions of other stars in the galaxy combined - which is why it can be seen at such distance from Earth. The edge of the dark circle at the center is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull (万有引 力),not even light can escape.

    "It is remarkable that the image we observe is so similar to that which we get from our theoretical calculations. So far, it looks like Einstein is correct once again." said Dr Ziri Younsi, of University College London -who is part of the EHT cooperation.

    Chinese scientists were involved in the observation through a telescope in Hawaii. They were also highly involved in follow-up data processing and theoretical analysis, said Shen Zhiqiang, head of the Chinese Academy of Sciences' Shanhai Astronomical Observatory and a member of the EHT international team.

    Shanghai and Taipei were selected as two of the cities to hold news conferences, together with Washington, Brussels, Santiago and Tokyo, a recognition of China's contribution.

    "In the fields of astronomy, radio astronomy, and space astrophysics, China has made a significant contribution to this global project," Falcke said.

    I was always blamed for watching too much cartoons. As I have said goodbye to my teenage, I shift to watching more movies to prove that I was a grown-up. Surprisingly, I found that movies have something in common with cartoons. They are unrealistic.

    Sometimes movies give people hope, including the hope of justice, the hope of tomorrow and almost everything else. A great number of people were once touched by certain movies. From time to time, movies try to deliver some decisive ideas to the audience. In this way, movies do cheer up many people to go on with their lives.

    It seems that there is a set formula in movies. We usually see the hero or heroine in the movies suffer a lot in the opening. Gradually and likely, the destination of them always comes to a turning point. So they have to struggle or make some important choices. Then the movie ends up with a happy finale. Or at least the hero finally manages to face his poor life with great courage somehow. However, when audience watch movies in the cinema, most of them just follow the story. Few of them may ask, “Will it happen in the real life?”

    Movies are also imitating the real life. Thus a movie, just like a novel, can never be the same as the real life. The setting of a movie is so ideal that we could hardly find it out in reality. The moviemakers just try their best to persuade the audience to believe the story is true. In a word, it is all just make-believe.

    For quite a long time, I think that the adults' world is realistic in the opposite way of the children's cartoon. However, the movies from the adult world turn out to be a made-up thing. At the very moment, I suddenly realize that movies are somewhat of the adult's fairy tales or cartoons.

    To sum up, other than false comfort such as movies and tales, we are more in need of the maturity of mind, so that we can face our lives bravely and correctly.

    Every four years on November 8, the American people will vote for the next U. S. president. Before election day, people following the presidential campaign will see many polls (民调). A poll is a public opinion study. Research organizations ask people questions about the candidates to find out who they support.
    For example, one of the poll is run by a professor at a university in the U.S. state of Connecticut. People who work for the polling service call likely voters on the telephone.
    How can one poll be so different from others? Here are some things to remember when you are looking at polls:
Not all polling groups are the same
    Some polls target specific groups of people. Many polls make sure they collect many different opinions. Sometimes, however, polling organizations receive money from groups that support a specific political issue. It is important to look at which group carried out the poll along with the results.
A poll's method is important
    Some polls are using new technology. Traditionally, polls are done over the phone. But that is slowly changing. Many polls are now done online. While online polls can produce good information, it is sometimes hard to reach as many different types of people over the Internet.
    Also important the size of the poll. Try to find out how many people were polled before believing its results.
Polls are not predictions(预测)
    Polls only show how people feel at one moment in time. They do not show what will happen in the future. Public opinion may change before the general election on November 8. Some things that could change the opinions of voters include: the debates on television, the release of the candidates' tax or medical records, and unexpected illnesses.

    Parents can cut the chances of their children getting fat simply by keeping them longer at table. Just three minutes extra at a family mealtime could help prevent child obesity. Research found that among poor families, the extra minutes at mealtimes made great improvement of a normal weight for the youth. The factors are likely to be communication and the importance of a scheduled mealtime.

    Dr Barbara Fiese said, “Children, whose families have a 20-minute meal over four times a week, weigh less than kids who leave the table after 15 to 17 minutes. Over time, those extra minutes per meal add up and become really powerful.”

    The researchers studied 200 family mealtimes, testing the effects of factors and mealtime behavior of families with children in primary school. They found that families, who said that shared mealtimes were an important part of family life and had special meaning for them, were less likely to have an obese child. Similarly, families, who talked more together and interacted more positively during the meal, were more likely to have healthy-weight children.

    Teaching low-income families how to make the most of family mealtimes was a wise idea. Dr Fiese said, “This is something we can target and teach.” She added, “It's also important to recognize the increasing differences of families and their sometimes complex living arrangements that may challenge their abilities to plan ahead and arrange a single time to communicate with each other.”

    Families in poorer US neighborhoods faced a lot of problems, including poor access to healthy food. But even so, regular high quality family mealtimes made a difference to the children's weight. Dr Fiese said, “Three to four extra minutes per meal will make a healthy weight more possible.”

    MacDonald's will soon remove cheeseburgers and chocolate milk from its Happy Meal menu to set a good example in offering a healthy diet for kids at its restaurants.

    Customers can still ask for cheeseburgers or chocolate milk with kids' meal, but MacDonald's said that not listing them would make them less likely to be ordered. Since it removed soda from the menu four years ago, orders for it with the Happy Meal have fallen by 14%.

    As MacDonald's is known for getting more business from families with children, it is especially important for it to offer a healthy diet instead of junk food. And the Happy Meal is a key part of that. The Happy Meal has long been a target(目标) of health advocates(拥护) and parents who link it to childhood obesity(肥胖症). To get rid of its bad image, MacDonald's has made many changes on the Happy Meal over the years, including cutting the size of its fries and adding fruit.

    Recently, the company replaced its former apple juice with a new kind of juice that has less sugar. MacDonald's wants all its Happy Meal choices to have 600 calories or fewer. It also wants less than 10% of the meal calories to come from fat and added sugar. The cheeseburger and chocolate milk didn't meet those new standards. However, MacDonald's is trying to cut sugar from chocolate milk and believes it'll be back on the menu eventually.

    There will be other changes. For example, bottled water will be added as a choice to the menu, but it will cost extra. Currently, the Happy Meal menu lists milk, chocolate milk, and apple juice.

    For international restaurants, MacDonald's said that a least half of the Happy Meal choices available must meet the new standards. Some MacDonald's restaurants are adding new menu items to obey. For example, In Italy, a grilled chicken sandwich was added to the Happy Meal menu.
