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.

    There is always something that happens in the world that everyone fears will happen to their town, city or country: natural disasters. The scariest part of it is that no one will ever see it coming. Though technology helps us prepare, but it never actually tells the people when it's going to hit. It is always estimated but the result is never 100% accurate.

    However, that is not the point of this article. Two different natural disasters in two different parts of the world have happened in the past few weeks. One was a major flood that has hit Louisiana in the United States. The other was an earthquake that hit Amatrice, Italy. However, there is a major difference in the news coverage of the two tragedies.

    As for the flooding in Louisiana, it is reported that this disaster is the worst to hit the United States since Super-storm Sandy and it'll cost at least $30 million. In only the first couple of weeks, 13 people had died. However, like me, many people did not hear about this tragic event. I did not learn about it until about three weeks after it happened.

    In Italy, however, it covered all media instantly. The earthquake in Italy happened on Tuesday morning. That same day, I was on Twitter and that was all that was over the news feed. Every other post was about the earthquake. Some would have the opinion that Amatrice, Italy was one of the most beautiful towns in that country. I got in deep sorrow because there were more people killed in this quake than the flooding. So far, they have a total of 73 dead and over one hundred missing.

    I understand that technically the earthquake in Italy was worse than the floods in Louisiana. However, I believe that if a natural disaster happens, they all should be equally covered and taken equally seriously. We are one world united and should be there for all of the people who are in need of help. We may not be able to accurately predict disasters but, we can surely lend a hand out for the needy.

    Friendships can be difficult-because often people aren't as honest and open as they should be. Sometimes, people end up getting hurt.

    Most problems with friendships come up because people are just too selfish to care about the things that their friends need. They care about their own needs much more, which makes it hard for friendships to work. However, being selfish is part of human nature. A person is put together in order to take care of himself and their own needs, not necessarily those needs of other people. Even though being selfish is something that all humans are born with, it is something that everyone should be against.

    The best thing to remember when you are a friend to anyone is that you need to treat your friends the same way as you'd like to be treated. This is wonderful advice for a friendship because it is really the only way to make sure that you are giving your friends everything you would want to be given in a friendship. Whenever you have a question about how you should treat a friend, it is easy to find an answer simply by asking yourself what you would like your friend to do for you, if he or she is in your shoes.

    Even if you're always thinking about how you'd like to be treated, and your friends are too, there are issuer(问题，忧虑) that come up from time to time in each friendship, and it is important to understand how to deal with these issues so that you can build stronger and healthier friendships. Issues like friends getting boyfriends or girlfriends and not spending enough time with their friends, or even friends finding new friends and leaving old friends behind are issues that will probably come up with one or more of your friendships. It is important to know how to deal with these issues so that you can keep your friends and make new ones. No one wants to have a broken friendship.

    One of the great concerns that ornithologists have is that climate change will throw the nesting activities of birds out of sync (同步) with the availability of food for the raising of chicks. For one species, the pied flycatcher, a new study shows that some of its clan are proving to be remarkably adaptable.

    Upon returning to Europe from their African wintering grounds, the flycatchers time their egg-laying to the short period when juicy caterpillars (毛毛虫) are most abundant. During the past three decades this caterpillar peak has advanced by three weeks. Pied flycatchers initially had difficulty adjusting, but over time have started laying their eggs earlier to grab the caterpillars. Some, though, are doing a lot more to improve their reproductive chances of success, according to a study in the Journal of Avian Biology led by Christian Both of the University of Groningen, in the Netherlands.

    Like most bird species, pied flycatchers have long been thought to lay a single clutch of eggs during the breeding (繁殖) season. This was widely considered to be a trait that wouldn't change. Then, in 2007, a Swiss team led by Dr Ravussin began to suspect that clutch numbers were flexible. They discovered a female pied flycatcher that immediately produced a second brood with a new male after raising an early set of chicks. Aware of Dr Ravussin's findings, Dr Both wondered whether this was just a single, odd instance or if second broods might be happening on a larger scale driven by the arrival of earlier springs. So, they cooperate to delve into the data to find out.

    The team studied pied-flycatcher populations in the Netherlands and Switzerland that were known to be among the earliest nesting members of the species. In total, they tracked the egg-laying times and hatchling-rearing success of 8,848 breeding pairs in the Netherlands and1, 372 in Switzerland between1980 and 2018. They found that since 2006, 11 cases of second broods were observed, all of them among the earliest breeders in both populations.

    Further studies ruled out that the birds were making up for a failed first attempt at raising chicks or that the second group of nestlings suffered.

    With no obvious downside to laying a double clutch, Drs Both and Ravussin conclude that the birds are attempting to double their annual reproductive output. While this behavior is still rare, they argue that if the tendency is driven by heritable genes (which it may well be), then a succession of early springs could make the strategy much more common.

    Last Thursday, Michael and Linda stood behind large food trucks distributing meals to 4,000 homeless people for their wedding reception on the border town of Kilis. The couple had decided that instead of hosting their friends and family for a traditional feast reception, they would feed the victims from an earthquake-stricken area.

    The idea came from the bridegroom's father, Ted, who volunteers for a Turkish relief organization. For the past few years, the organization has distributed daily meals to thousands of people who have suffered from natural disasters. He approached a representative of the organization and suggested that the family cover part of the costs of feeding them for the day.

    Then he told his son, who was surprised by the suggestion, but soon won over. When he told that to the bride, she was really shocked but finally accepted because in southeastern Turkey there is a real culture of sharing with people in need. They love to share their food, their table and everything they have. And afterwards she was quite amazed about it. So, they arrived at the distribution center on Thursday to spend the day serving food and taking photographs with their grateful recipients(接受者).

    On Tuesday evening, the newly married couple were still pleased with their decision to quit a personal celebration for one with a greater good. "It's like sharing a dinner with your friends and family who have this kind of thing on a daily basis or sharing something with people who don't even have the most basic things," Michael said. "Hopefully, this will also give the start for other wedding dinners to be held here with our brothers and sisters in need."

    In the shadow of Kenya's Mount Kilimanjaro, nine Rothschild giraffes, the rarest giraffes on the planet, are free to wander at the English-style manor (庄园). Every day shortly before 9am, they come up to the house and stick their heads through the windows and doors in search of morning treats. The manor's owners, Tanya and Mikey Carr-Hartley, share their dining table with them. And now the couple are sharing the fantastic experience with the public by opening the manor gates to guests at the giraffe hotel, the only hotel of its kind in the world. Now, guests can feed the giraffes at breakfast but can also get up close to them from their second-floor bedrooms.

    Mr and Mrs Carr-Hartley, both 38, spent their childhood living close to the house in Nairobi and have always been enthusiastic about the animals. Tanya said, "Mikey and I grew up near this manor house when we were children. We are both third generation Kenyans and have always wanted to work in conservation. Mikey's family have been related to the protection of animals for many generations. His granddad helped the removal of giraffes as far back as the 1930s because the Rothschild giraffes lost much of their natural living space. When the house came up for sale, we jumped at the chance to buy it as we had always dreamed of owning it. Now, we were absolutely overjoyed to do something for the giraffe protection. Having the giraffes so close is very special and something which people can now experience by staying in one of the ten rooms at the hotel."

    A conservation project to save them was started at the manor in 1974 by the previous owners. "The previous owners ran a very successful breeding (繁殖) programme, where many giraffes were set free into the wild and we hope to continue," said Tanya.
