After her college closed for the first lockdown in March 2020, Finty Royle was looking for something to do in her community to help people. When a local company said that it wanted someone to deliver free meals for families in need, it was perfect for Royle. She cycled 25 miles around her area every day to hand out the meals. Speaking to The Week Junior, she said, “The children got very excited to see me every day. There was even one family who had drawn a picture in chalk of someone cycling through a rainbow in front of their house.”

Royle, aged 19, has now become a youth member of a charity called Magic Breakfast, which aims to provide pupils across the UK with healthy breakfasts to help them learn as well as they can at school. She says the best thing you can have for breakfast is porridge because it’s good for you and it keeps you going for the whole morning.

Magic Breakfast’s youth members, including Royle, have written to Prime Minister Boris Johnson to ask him to increase the government’s funding for free school breakfasts by £75 million. As food prices rise across the UK, more families may find it hard to afford school meals. Royle believes it is important to try your best to help your local community. “You can create change yourself,” she said.

What did your street look like a hundred years ago? It has probably changed over time. U.S. Route 66 was a road that saw many changes, too. This famous road has been written about in books. It has been the subject of TV shows and songs. Route 66 stretched 2,448 miles (3,940 km)across the United States, and it carried a lot of history.

For hundreds of years, native Americans followed animal tracks to hunt. Later, mountain men blazed trails along the same paths in order to set their fur traps. Next came the pioneers moving west in wagons. Gold was discovered in California in 1849. People used the same route to seek their fortunes（财富）there. About 10 years later, railroads were built along the flat and wide route.

In 1908, Henry Ford began to manufacture automobiles. Motorists took off into the countryside. They wanted to drive on paved roads! In 1926, Route 66 became an official U.S. highway. It was the first paved road to run all the way from Illinois to California. During the 1930s and '40s, people drove west on U.S. Route 66. They were looking for work on farms and in wartime plants. In the 1950s and '60s, many Americans enjoyed taking road trips. They drove along Route 66 to visit the Grand Canyon and Disneyland.

Wider, straighter, and safer highways were built. Old Route 66 was used less and less. In 1985, it was officially removed from the U. S. highway system. The parts that still exist today are called Historic Route 66. Most of the old Route 66 filling stations, diners, and motels are closed. But U.S. Route 66 is still remembered as a road of dreams that carried people west.

What do Batman, Black Panther, Spider-Man and Superman all have in common? Not only are they all superheroes, they’re all orphans too.

Bruce Wayne is inspired to fight crime as Batman after his parents are killed in a robbery. Peter Parker is raised by his Aunt May and Uncle Ben after his parents die in a plane crash. The alien Kal-El, otherwise known as Superman, is sent to Earth by his parents before his home planet of Krypton is destroyed. Upon his arrival he is discovered by Martha and Jonathan Kent, who raise him as their own. T’chala means “Orphan King”, after he takes the title of Black Panther from his late father.

Now, a new exhibition at London’s Foundling Museum is exploring the way orphans are shown in comics and other types art from around the world. Opened in 2004, the Foundling Museum was built on the site of the Foundling Hospital, which looked after children who had been left without people to care for them. “Foundling” is a term used for children who have been given up by their parents and left somewhere for others to find. The Foundling Hospital still works today with the children’s charity Coram. Superheroes, Orphans & Origins: 125 Years in Comics looks at famous DC and Marvel comic book characters, old newspaper comic strips, graphic novels such as Zenobia and Japanese manga including Sunny. The collection includes international comics rarely seen in the UK, and original art drawn for the exhibition, such as Up in Flames by Woodrow Phoenix.

The exhibition runs until 28 August. You have to book but under-21s get in free. You can find out more about the show at tinyurl.com/TWJ-comicorigins.
