A food additive is any substance that is added to food. Many people are put off by the idea of “chemicals in food”. The truth is that all food is made up of chemicals. Natural substances like milk, as well as man-made ones like drinks on sale in the market, can be described by chemical formulas. Some chemical substances are indeed harmful, but a person who refuses to consume any chemicals would find nothing to eat.
The things we eat can be divided into natural and man-made substances. Some people feel that only natural foods are healthy and that all man-made ingredients are to be eliminated. But many natural chemicals, found in plants and animals, are harmful when eaten, and some laboratory-made substances increase the nutritional value of food. Other chemicals have natural and man-made forms that are exactly alike: vitamin C is vitamin C, whether it comes from a test tube or from an orange.

4 . Hope to have a cultural trip? Why not try these biggest and best exhibitions around the world?
Acts of Creation
The pains and joys of motherhood are not always described with as much care and detail as in this exhibition. With over 100 artworks by over 60 artists, three themes of motherhood — creation, maintenance and loss — will be explored through paintings, photographs, sculptures, sound and films.
Time: Until November 12
Location: Midlands Arts Centre, Bristol
From the Other Side
An exhibition on horror? It might not sound a good one for those who are not brave. However, you needn’t worry: this collection is far different from scary paintings. Instead, these artworks of 19 Australian artists aim to raise questions about horror in the women’s views.
Time: Until December 23
Location: ACCA, Melbourne
Modes and Characters
This museum exhibition is taking a look at the history of modern graphic design and explores how computer-based publishing technology has changed the world of design. Special focus is given to the work of Japanese designers and Japan’s different graphic culture, with individual exhibits ranging from magazine covers to the posters seen on trains.
Time: Until October 30
Location: 21 Design Sight, Tokyo
Hip Hop and Contemporary Art
Hip hop has had an influence on culture over the last 50 years, and this exhibition is taking a deep dive into its history. It ranges from fashion and photography to video and sculpture. Highlights include a large-scale installation from Lauren Halsey, the work of artist Hank Thomas, and photographs from Deana Lawson.
Time: November 5
Location: Art Gallery of Ontario, Toronto

6 . “Never give up! Never give up!” sang my two young children, Max and Charley, as they marched barefoot behind their grandmother Mimi on another adventure, off the beach where they had spent the day building sand castles and beating the waves. This time, they were seeking the ice-cream truck.
Over the years, Mimi had become our family’s source of positivity through her effort. My father’s death left her to raise me and my ten-year-old brother alone at forty. She faced tragedy that is powerful enough to cloud just about anyone’ s outlook. Instead, she challenged herself to find joy every day. She was always up for a new challenge, whether parasailing over the Gulf of Mexico, or signing up for tap-dancing classes at fifty. Leading by example, Mom taught us how much one could accomplish with a positive attitude.
She has taken the same approach in her relationship with her grandchildren. Prior to starting her adventure with Max and Charley that hot July afternoon, Mimi heard the familiar sound of the ice-cream man’s bell from her beach chair. The ice-cream man’s visit is a daily occurrence at the beach, but one must be quick to catch his truck. Max and Charley were disappointed when they didn’t catch him in time that day, until Mimi’ s eyes sparkled and explained that they could rush to find it at its next stop.
They walked block after block. My kids’ tiny legs were tired, but they went on. After about twenty minutes’ walking, Max spoke out loud, “Maybe we should give up.” Charley responded with a quick “No way! Never give up!” and resumed her singing with Mimi.
Just two blocks later, they found it. Max and Charley screamed with excitement, “Never give up!” Simple though it was, that phrase has become our battle cry (口号) for the challenges we face. Upon hearing those words, they are instantly transported to a positive state of mind—where the next ice-cream truck is just around the corner.

In Mr. Russo’s classroom, excitement filled the air as he announced, “We’re down to our final two spellers!” Jasmine couldn’t hide her joy, confident she was going to win. Finn, her competitor, reached out for a handshake, wishing her good luck. But Jasmine replied with a smile, “Luck has nothing to do with it,” leaving Finn embarrassed.
Then, it was Finn’s turn to spell his word. “Apology,” Finn took a deep breath and spelled, but he got it wrong. Jasmine watched closely, waiting for her turn. When she spelled “apology”, she stressed the letters Finn missed. After spelling the final word “Arrogant” (傲慢), Jasmine was announced the winner.
At lunch, Jasmine couldn’t stop herself from showing off as she walked by Finn and his friends. “How hard can it be to spell a few words?” she bragged (吹牛). Before they could answer, she walked away with pride.
The big day of the spelling bee showed Jasmine a different picture. Surrounded by older students, she started to doubt herself for the first time. She hadn’t thought about the tougher words she might face. A comment from Josh, a fourth grader, that “apology” was an “easy” word, made her worry. “Maybe I should have studied the list of words Mr. Russo gave the class,” Jasmine thought to herself.
As Principal Lopez introduced each of the spellers, cheers from each student’s classmates came from different areas of the hall. When Jasmine’s name was announced, most of Mr. Russo’s class clapped for her except Finn, who seemed to be looking at her angrily.
As the bee went on, Jasmine felt increasingly nervous with each word spelled right by others. Finally, it was her turn. Jasmine walked slowly to the front of the stage, her earlier confidence now mixed with caution. The audience watched, waiting. “Please spell ‘caterpillar’,” Principal Lopez asked.
Jasmine’s heart sank as she didn’t know the word.
