In US, the potato is one of the most widely consumed crops. French fries are commonly found in typical American fast-food burger joints and cafeterias. French fries were introduced to the US when Thomas Jefferson served them in the White House during his presidency from 1801 to 1809. Potato chips are popular with consumers as well.

    The humble potato is more than just a kind of food. In many ways it's part of the American pop culture. Let's take a look at some pop culture potatoes.

Mashed Potato dance

    The Mashed Potato dance is a craze that began in 1962. The name of the dance came from the song it accompanies, Mashed Potato Time, performed by American R&B singer Dee Dee Sharp. The move vaguely resembles that of the Twist dance style, by Sharp's fellow Philadelphian.

Hot Potato!

    Hot Potato! is an action puzzle video game released in 2001. In the game the player must drive a bus and clear the road of alien potato beings. The potato beings are either red or blue; when two like-colored potatoes touch each other, they disappear. Over the years, Hot Potato! has received mostly positive reception from critics.

Mr. Potato Head

    Mr. Potato Head is an American toy invented by George Lerner in 1949. The toy consists of a plastic potato model and a variety of plastic parts like hands, feet, ears and mouths. In 1952, Mr. Potato Head became the first toy advertised on television. This commercial revolutionized marketing and caused a boom that solidified this toy's place in American pop culture.

    Do you find yourself reaching for just one more cup of coffee to get through the day?Are you tired of being tired?Instead of relying on things like coffee or sugar for energy,get happy by eating more foods that give you energy through nourishment.Here are four foods that can help improve your energy levels.

    Hemp Seed

    A complete protein,rich in fiber and omega-3s,hemp is a great low-glycemic（低胰岛素）addition to any diet.The glycemic index (GI) is a measurement of how fast the carbohydrates in food are broken down into glucose（葡萄糖）and how much it will affect your blood sugar.Fiber,fat and protein all lower the GI of a food,which is why hemp seeds (along with nuts,seeds,whole grains and legumes) are low-glycemic.Look for hemp seed oil for salad dressing,and hemp seeds to be added into salads.

    Soaked Almonds

    Raw almonds are nutrient dense,and soaking them releases（释放）higher nutrition potential.Soaking increases vitamin levels and removes the enzyme（酶）inhibitors that slow down digestion.I soak my almonds in water overnight (at least eight hours) and then dry them.

    Quinoa

    It is 20-percent protein,making it a balanced source of carbohydrates.Even though you feel like you're too busy to make home-made meals,quinoa is a fast food that cooks in less than 15 minutes.

    Green Tea

    Caffeine from green tea feels steadier and less sharp than the spike and crash with caffeine from coffee.This is likely because green tea contains L-theanine,a kind of acid found in tea that helps promote relaxation.      .

    I first met Paul Newman in 1968, when George Roy Hill, the director of Butch Cassidy and the Sundance Kid, introduced us in New York City. When the studio didn't want me for the film - it wanted somebody as well known as Paul - he stood up for me. I don't know how many people would have done that; they would have listened to their agents or the studio powers.

    The friendship that grew out of the experience of making that film and The Sting four years later had its root in the fact that although there was an age difference, we both came from a tradition of theater and live TV. We were respectful of craft(技艺)and focused on digging into the characters we were going to play. Both of us had the qualities and virtues that are typical of American actors: humorous, aggressive, and making fun of each other - but always with an underlying affection. Those were also at the core(核心)of our relationship off the screen.

    We shared the brief that if you're fortunate enough to have success, you should put something back - he with his Newman's Own food and his Hole in the Wall camps for kids who are seriously ill, and me with Sundance and the institute and the festival. Paul and I didn't see each other all that regularly, but sharing that brought us together. We supported each other financially and by showing up at events.

    I last saw him a few months ago. He'd been in and out of the hospital. He and I both knew what the deal was, and we didn't talk about it. Ours was a relationship that didn't need a lot of words.

    Fire Prevention Information

    The University of Adelaide employs a full-time staff of fire prevention professionals. They inspect all campus buildings and test and maintain all sprinkler(喷水灭火装置) systems, fire alarms, and fire extinguishers (灭火器). They also provide educational programs on fire safety in the residence halls. Whenever you move to a new area, you should locate the fire alarm pull stations and the two exits nearest your room.

    Fire Alarms

    The floors of all campus buildings are equipped with manual(手动的) fire alarm systems which include fire alarm pull stations and pipes. Most are also equipped with automatic fire alarm systems consisting of heat detectors, smoke detectors and sprinklers. For your safety, never tamper with(胡乱摆弄) these systems. False fire alarms are illegal and may lead to imprisonment.

    Fire Drills

    A fire drill will be conducted in your residence hall every semester. During a fire drill, please do the following:

    ·Take your room key and ID, close and lock the door to your room.

    ·Exit immediately from the nearest emergency exit; do not use a lift.

    ·Meet outside of your residence hall and wait for further instructions.

    Fire Extinguishers

    Fire extinguishers are located on each floor and in each apartment. Use a fire extinguisher only if you have been trained to do so. Irresponsible use of a fire extinguisher can create a dangerous situation for other residents and could result in damage to personal property. Misuse of a fire extinguisher will result in fines.

    Smoke Detectors

    A smoke detector is on the ceiling in your room. Some buildings also have heat detectors on the ceilings. Do the following to ensure the safe operation of your smoke detector:

    If your smoke detector is working properly, the red light should be on. If the red light is not blinking(闪动), contact residence hall staff immediately.

    Do not cover or block your smoke detector in any way.

    If a smoke detector sets off an alarm and there is no fire or smoke, inform your hall staff.

    I had about 10 minutes to exercise before I had to pick up my two older daughters from school yesterday. It was a busier day than usual for me with a couple of meetings besides my regular work.

    Years ago, I would have put off my workout and would have left things for the next day. But since it was a busy day as well, I knew that I may not have all that much time either. So, I picked up my kettle-bell (哑铃) and went to town for 4 minutes.

    See, 4 minutes, if that's all you've got, is enough to give your body a great fat-burning exercise. How did I get a killer workout in 4 minutes? I used a training workout discovered 10 years ago by a Japanese Sports Scientist called a TABATA.

    It includes 20-second periods of warm-up, followed by 10-second periods of rest and 4-minute straight exercise. How is a 4-minute exercise able to burn fat? It all depends on the quality of work you do. Not on the quantity. Here's how I did it yesterday.

    You should never forget your warm-up. A TABATA workout is 20 seconds of 2-arm Kettle-bell swings, 10 seconds rest, 20 seconds push-ups, and 10 seconds rest. You should do those 4 rounds. That's it. I was done in a total time of 8 minutes by the time and when I got to school my heart was still pumping pretty hard.

    A healthy body is needed for studying and working, and efficiency (效率) is the key to building a great body in the least amount (数量) of time possible and you can't get more efficient than a 4-minute workout.

    Record fires sweeping across the Amazon this month have been catching global headlines as scientists and environmental groups are worried that they will worsen climate change and threaten biodiversity(生物多样性).

    As the largest rainforest in the world, the Amazon is often called "the lungs of the world". It is also home to about 3 million species of plants and animals, and 1 million local people. The vast lands of rainforest play an important role in the world's ecosystem because they take in heat instead of it being reflected back into the atmosphere. They also store carbon dioxide (二氧化碳)and produce oxygen, making sure that less carbon is given off, mitigating the effects of climate change.

    "Any forest destroyed is a threat to biodiversity and the people who use that biodiversity," Thomas Lovejoy, an ecologist at George Mason University told National Geographic. "The shocking threat is that a lot of carbon goes into the atmosphere," he stressed. "Facing the global climate change, we cannot afford more damage to a major source of oxygen and biodiversity. The Amazon must be protected," U.N. Secretary General Antonio Guterres said.

    Data from the National Institute for Space Research (INPE) show that the number of forest fires in Brazil quickly increased by 82 percent from January to August this year from a year ago. A total of 71,497 forest fires were recorded in the country in the first eight months of 2019, up from 39,194 in the same period in 2018, INPE said. "It's reported that the forest areas in the Brazilian Amazon have decreased something between 20 and 30 percent compared to the last 12 months," Carlos Nobre, a researcher at the University of Sao Paulo, told German broadcaster Deutsche Welle.

    Brazil owns about 60 percent of the Amazon rainforest, whose drop could have severe results for global climate and rainfall. The size of the area ruined by fires has yet to be determined, but the emergency has transcended(超出）Brazil's borders, reaching Peruvian, Paraguayan and Bolivian areas.
