While watching the Olympics the other night, I came across an unbelievable sight. It was not a gold medal, or a world record broken, but a show of courage.

    The event was swimming and started with only three men on the blocks. For one reason or another, two of them false started, so they were disqualified. That left only one to complete. It would have been difficult enough, not having anyone to race against, even though the time on the clock is important.

    I watched the man dive off the block and knew right away that something was wrong. I'm not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold—his arms were waving in an attempt at freestyle. The crowd started to laugh. Clearly this man was not a medal competitor.

    I listened to the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes and you could tell he was worn out.

    But in those few awful strokes, the crowd had changed.

    No longer were they laughing, but beginning to cheer. Some even began to stand and shout “Come on, you can do it!” and he did.

    A clear minute past the average swimmer, this young man finally finished his race. The crowd went wild. You would have thought that he had won the gold, and should have. Even though he recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors.

    Just a short year ago, he had never even swum, let alone race. His country had been invited to Sydney.

    In a competition where athletes remove their silver medals feeling they have somehow been cheated out of gold, or when they act so proudly in front of their competitors, it is nice to watch an underdog.

    Soft winds blew throughout the Windy City today. We welcomed the winds, as it was another hot day in Chicago. The wind blew, bringing us some coolness—and making the weather not that hot. But it was a beautiful summer day with a blue sky.

Chicago is a great city for eating, and we have enjoyed tasting the different foods. Last night, we tried one of the city's most famous foods: deep-dish pizza. Chicago claims credit for the rich and cheesy thick-crust pizza, covered with a sweet tomato sauce. We topped it with olives and green peppers.

       We were touring the city, mainly looking for delicious local foods. Today, we enjoyed a Polish specialty at lunch: Pierogis, an Eastern European dumpling-like dish, filled with foods like potatoes, cheese, mushrooms, cabbage and meat. Polish immigrants started settling in Chicago in the 1850s, and the city has one of the largest Polish communities in the U.S.

    We took a break from exploring the city to talk with some of you! Ashley and Caty logged onto the Internet for an on-the -road version of TALK2US. We spoke to an English teacher in Tokyo, Japan, and a graduate student in India.

Meanwhile, Adam searched for some locations around the city to shoot some video. He chose a spectacular spot: Navy Pier, Chicago's most-visited attraction. The winds from Lake Michigan keep visitors cool, and the view of the Chicago skyline never fails to impress. In fact, the view made all of us head over heels!

    Our time in Chicago has come to an end. Tomorrow, the true journey begins, as we pass through Illinois and into Missouri via Route 66. Springfield, the home of Abe Lincoln, and St. Louis, the “gateway to the West,” wait for us.

    Fix it on your own

    Did you know that a bowl of rice could save your iPod if you drop it in a swimming pool by accident? Or that the camera on your phone could tell you what's wrong with your TV remote control(遥控器)? The experts at Geek Squad have made a gadget (小机件) rescue guide. So, let's take a look at some of their useful advice.

    How to get more juice out of your phone battery (电池)

    If your battery goes dead but you need to get a number or send one last text, try warming it up. That may give you a tiny bit of power. Take the battery from the phone and rub it between your hands. Or warm it under your arm for a few minutes. Then try to start the phone-but use it quickly.

    What to do if your gadget gets wet

    First, try drying it out with a vacuum cleaner(真空吸尘器). If a vacuum cleaner isn't at hand, fill a pot or bowl with uncooked rice and put your wet gadget inside. The dry, uncooked rice will absorb all the water and, after a few hours, you should be able to use the gadget. Don't forget to remove the battery and SIM card before you dry it.

    What to do if your TV remote control stops working

    If replacing the batteries doesn't work, get the camera function up on your phone and point the remote at the lens (镜头). When you press a button on the remote, if it is working, the glass bobble (小球) at the front of the remote will light up when you look at it on the screen of your phone. This is because the screen on a phone or digital camera picks up infrared rays (红外线), even though your eyes don't. If the glass bobble doesn't light up, the remote is broken. If it does, the receiving device is broken.

    Philadelphia, Pennsylvania is America's fifth largest city. Once a major American colonial city, it is the home of America's first library, its first hospital, and its first zoo. Now it is also the first US city to be named a World Heritage City. On November 6, 2015, Philadelphia joined more than 260 other cities that have been recognized for their influence on the world. These cities include Paris, France, Florence, Italy, and Cairo, Egypt.

    "Today marks the start of a new and exciting chapter in the history of Philadelphia," remarked Philadelphia Mayor Michael Nutter when the announcement was made. "As a World Heritage City, Philadelphia is being officially recognized on the global stage for its wealth of contributions to the world.

    To be named a World Heritage City, a city must be home to a UNESCO World Heritage site. UNESCO World Heritage sites are selected for their universal value and significance. For Philadelphia, the site is Independence Hall.

    Independence Hall is where two of the most important documents in US history—the Declaration of Independence and the US Constitution—were adopted. The Declaration of Independence, approved on July 4, 1776, united the 13 former British colonies and declared them independent from British rule. The US Constitution, signed in 1787, established the American democratic system of government. A democracy is a system of government in which the people elect their leaders. The Constitution later spelled out the basic freedoms American citizens have.

    Philadelphia Deputy Mayor Alan Greenberger says the city's selection as a World Heritage City also reflects its educational, cultural, and economic achievements. The city is home to dozens of colleges and universities, and many museums, such as the Philadelphia Museum of Art. "Philadelphia has rightfully earned its place as one of the greatest cities in the world." Greenberger says.

    A hospital has been forced to ban Pokemon Go players from the site after a monster hub(妖怪枢纽站) was found in the A&E department. Royal Stoke University Hospital discovered that its casualty unit(急诊室) is on the same spot as a Pokemon Go 'gym' ­­ where players can train their newly caught Nintendo creatures.

    The University Hospitals of North Midlands Trust agreed last week that patients can play Pokemon Go on wards because walking around is healthy. But the Trust has been forced to post a warning on its website about public access to A&E. It said if Pokemon Go becomes a major annoyance it would ask Nintendo­­ which decides on the locations of the virtual gyms according to GPS­­to have it removed from the premises(道馆).

    Kevin Parker, associate chief nurse, said, "Members of the public who do not need to be at Royal Stoke should not attempt to enter A&E or any other part of the hospital building to play the game. The A&E department is incredibly busy this summer. We want the public to understand that anybody who visits the hospital solely to play the game will provide an unwanted distraction to the important work of the hospital. I'm also aware of various reports in the media of unsafe areas that the game has been played in."

    "Royal Stoke University Hospital is a safe area where gamers can enjoy Pokemon Go." Michelle Harris, the Trust's manager, said the game could still be played by those already in hospital. "We recognize that the Pokemon Go game encourages walking and exercise, which is something that the Trust is equally keen to promote," she said.

    There are a number of "walking routes" established throughout the Trust that can be used to combine walking and playing the game. "Walking just 30 minutes, five times a week, can help reduce the risk of preventable illnesses such as obesity, diabetes, and heart disease."

    There have been several warnings about the game since its UK release. Last week a group of teenagers in Wiltshire were left stranded almost 100ft underground after they got carried away searching for Pokemon Go characters. The four boys, aged 16 and 17, ended up getting lost and had to wait to get a phone signal before they could call for help. Eventually, they contacted Dorset and Wiltshire Fire and Rescue team, who took them to safety. Damien Bence, of the fire and rescue team, said: "Pokemon Go is obviously leading people into dangerous situations."
