Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health．

    In a new study, the researchers found that pizza is a large source of calories, saturated fat(饱和脂肪)and salt in children's diets．Children should not eat more than two slices of pizza for a meal，and should pair that with salad, rather than with another high-calorie food，the researchers concluded．

    “Parents should aim to control pizza consumption(消费), particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands．”Said Lisa Powel, director of the Illinois Prevention Research Center．

    Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them．Studies have found pizza is among the greatest sources of calories for children．

    “Since pizza remains a common part of children's diet, we need to make 'healthy' pizza．”Powel said．To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content,” she said．

    Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research. “Many foods are eaten too frequently and in large sizes,” said Tindall．To solve the problem, people don't have to give up eating pizza, but instead, they can eat smaller and healthier pizza，”she said．

    “Make it at home, instead of ordering it out where you don't have any control over how it's made.” Tindall said. “When we make it at home, we can choose healthier ingredients，increase the vegetables, reduce fat, and put in less cheese．Pizza doesn't have to be just pepperoni(意大利辣香肠)and cheese．”

    November 11 is Veterans Day in the United States. A "veteran" is anyone who has served in the armed forces. The term "veteran" is not just for those who have served in wars. It describes anyone who has ever been in the army.

    On November11, people hold ceremonies(仪式) and parades(游行) to mark Veterans Day. Public officials take part in the events. Army bands play. And soldiers fire guns into the air to remember those who died in service to their country.

    The history of Veterans Day relates to World War I. Many people at the time called it "the war to end all wars." The United States entered the fighting in Europe in 1917. Over 13 million men and women were reported for duty in the army. World War I ended at 11 o'clock in the morning on November 11, 1918. The following year, President Woodrow Wilson signed an official statement to celebrate November 11th as Armistice Day in the United States. It would be a day to honor the men and women who had served in the U.S. armed forces during the war. In 1926, Congress made Armistice Day a national holiday.

    But new problems were on the way. Soon, everyone knew that World War I would not be the war to end all wars. In all, more than 4,000,000 Americans served in the armed forces during the first World War. And 16 million would serve during the second one.

    Armistice Day in 1945 was a special day in the United States. Germany had surrendered in May 1945 and Japan in August. Most men and women who had served in the war were home. So, instead of honoring just veterans of World War I, Americans also honored veterans of World War II. In 1954, Congress decided to change the name of Armistice Day. The holiday became Veterans Day.

    Have you ever pressed the pedestrian button at a crosswalk and wondered if it really worked? They're called "placebo(安慰剂）buttons"一buttons that mechanically sound and can be pushed, but provide no functionality.

    In New York City, only about 100 of the 1, 000 crosswalk buttons actually function. Crosswalk signals were generally installed before traffic jam had reached today's levels.

    But while their function was taken over by more advanced systems—such as automated lights or traffic sensors — the physical buttons were often kept, rather than being replaced at further expense. Other cities, such as Boston, Dallas and Seattle, have gone through a similar process, leaving them with their own placebo pedestrian buttons. In London, which has 6, 000 traffic signals, pressing the pedestrian button results in a reliable "Wait" light. But that doesn't necessarily mean that the "green man"— or "pedestrian stage" in traffic signal design profession — will appear any sooner.

    "We do have some crossings where the green light comes on automatically, but we still ask people to press the button because that enables accessible features,'' said Glynn Barton, director of network management at Transport for London.

    These features, such as blind tracks and hearable traffic signals, help people with visual disorder cross the road and only function when the button is pressed. As for the lights, a growing number of them are now combined and become a part of an electronic system that detects traffic and adjusts time frequency accordingly (giving priority to buses if they're running late, for example), which means that pressing the button has no effect.

    According to Langer, a Harvard psychologist, placebo buttons give us the illusion (错觉)of control — and something to do in situations where the alternative would be doing nothing. In the case of pedestrian crossings, they may even make us safer by forcing us to pay attention to our surroundings. "They serve a psychological purpose at the very least," she added.

    For many people, the Transformers movies are the greatest Hollywood blockbusters (大片). And among the Transformers themselves, the yellow Autobot named Bumblebee is certainly the favorite. He may be one of the smallest and weakest of the alien machines, but he is always loyal to his friends and shows great bravery in battle.

    In the new film, Bumblebee is found in a junkyard (废车场) and is full of honeybees. He always finds himself in awkward (尴尬的) situations, but people like his cute and naive looks. In addition to his blue eyes, Bumblebee's body language and movements are adorable. At one point, he sits with his legs straight out, with his huge feet making him look like a 5-year old trying on his dad's shoes.

    Bumblcbee is the Transformer who has the greatest affinity (亲和力) with humans. He starts journey with Watson, who is at a loss about her future and wants a friend. As a result of their adventure together. Watson grows up and starts to work toward her life goal of becoming a musician. As for Bumblebee, as we know, is a robot from outer space, he now has a better understanding of his task to protect the Earth. Every adventure has a beginning, as the movie poster puts it. More importantly, every adventure needs a good partner. The considerate, positive and warm Bumblebee is definitely a good choice according to US actress I Hailee Stcinfeld, who plays Watson in the film.
