It’s hard to say no to hamburgers, French fries and all of the other junk food. However, eating too much junk food can harm your body, especially if you’re between the ages of 10 and 19. “Junk food shapes teenage brains in ways that harm their ability to think, learn and remember. It can also make it harder to control impulsive (冲动的 ) behaviors,” said Amy Reichelt, at Western University, Canada. “It may even raise a teen’s risk of mental (精神上的) problems.”
Reichelt and two other researchers reviewed more than 100 studies, about how poor food choices can affect teenage brains. They found teenagers are more sensitive (敏感的) than any other age group to foods with a lot of fat and sugar as their brains are not yet fully formed.
Teenage brains are still developing the ability to notice risks and control actions. The prefrontal cortex (前额皮质) is the part of the brain that tells us we shouldn’t eat chips all the time and helps us control ourselves. However, this part doesn’t fully develop until we are in our early 20s.
Meanwhile, teen brains get more excited from rewards (奖励). The parts of the brain that make us feel good when we do something enjoyable — like eating tasty foods — are fully developed by the teen years.
In fact, these parts are even more sensitive when we are young. That’s because dopamine (多巴胺 ), a natural chemical that makes us feel happy when we experience something good, is especially active in teenage brains.
Therefore, the teen brain has two attacks against it when it comes to saying no to junk food. “It has an increased drive for rewards and reduced self-control,” said Reichelt.
Reichelt and her team did their own study using mice, whose brains develop much like our own. They discovered that “teenage” mice that had high-fat foods performed worse on memory tests than those eating normal foods. Researchers said the high-fat foods may make the mice’s prefrontal cortex work less effectively.
So, what’s the best way to say no to junk food? The answer is exercise. When we exercise, the brain becomes less sensitive to food, besides this, it also helps our brains grow and become better able to make wise decisions and control our behaviors.

4 . Today, there are many ads on social media and most ads are impossible to avoid, especially when people follow some famous influencers. The influencers are Internet celebrities(名人) with lots of social media followers, and their posts can influence lots of people. The new data from a research made by a teen researcher shows that these influencers promote(推销) more unhealthy foods and drinks than other celebrities.
The new findings come from Nyasha Nyoni, 17. Nyasha is an athlete who likes cooking in the kitchen. Being healthy is important to her. She used to look at food and drink ads on mainstream ( 主 流 ) media. “I thought it would be interesting to look at social media,” Nyasha says, “because it’s a newer technology and it is growing so quickly.” Social-media platforms are often paid to promote foods and drinks. Nyasha wondered how healthy those products were, so she chose to make a research about it.
First, Nyasha needed a list of Internet celebrities’accounts(账号). She picked 100 athletes from a Forbes list of the world’s highest-paid athletes. Her list of 100 musicians came from Billboard’s hot 100 songs. And she picked 100 biggest influencers on social media. Nyasha looked through their posts about promoting foods and drinks in 2019 and 2020. It turns out that the influencers promoted more snack products than other groups. Snacks were the unhealthiest food on social media.
Nyasha was surprised by the result of her research. It didn’t match up with her experience or other studies. She’d expected influencers to promote more diet-related products. However, snacks were the most popular type of products by all three groups. Fruits, vegetables and water were least promoted.
“These findings could encourage new social media rules to protect young users from unhealthy ads,” Nyasha says, “Nearly four out of every ten social media users are between the ages of 13 to 24. Influencers’ ads may be especially alluring(有吸引力的),” she says, “The influencers may be seen as more relatable than mainstream celebrities. As a result, young users may have fewer doubts about the products they promote”.
This study has changed the way Nyasha sees her own social media. She has unfollowed some people who pushed unhealthy habits. She honestly thinks everyone should do that. Young users should get to construct(建构) their own social-media feeds to make that online space as healthy and positive as possible.

6 . During the 2016 Rio Olympics, people were surprised to see the round, purple marks on the body of the famous American swimmer Michael Phelps. What happened to him? In fact, he just visited a doctor of Traditional Chinese Medicine (TCM) and had “cupping” (拔火罐).
Massage (推拿) and acupuncture (针灸) are two other important kinds of TCM. Chinese massage can make you relaxed and fresh. Acupuncture takes away pain, though the look is funny.
TCM is an important part of Chinese culture. The earliest medical classic in China, Huangdi’s Classic on Medicine, came out more than 2,000 years ago. The book is about the relationship between man and nature. Nature keeps balanced if yin and yang work well together. TCM helps to do that Quit especially, for some health problems, a doctor of TCM will not give you medicine. Instead, he may give you just a food plan and right ways to eat.
For example, it is common to eat on the way to school at our desk, or in front of the TV. But TCM thinks it’s wrong. Here are the correct ways: sit down to eat. While eating, turn off the TV and get away from the work desk. Eat seasonal foods. Do not miss any of the three meals. Also, get your body moving often. Just as the saying goes, “Running water is never stale.”
Nowadays, Traditional Chinese Medicine is becoming more and more popular around the world. A government report says that people in 183 countries and areas are now using TCM.

7 . ① One day, you open the fridge and find some moldy(发霉的) food. But before you can throw it away, your mother stops you. She doesn’t want to waste food. She cuts off the moldy part and eats the rest. Is it safe to do this?
② Most kinds of mold(霉菌) are bad for us. It can grow on almost all kinds of food. Mold is usually green, white, black or grey. Mold makes food soft and changes its color. Moldy food tastes quite bad and it’s not safe to eat. So how do you deal with this situation?
③ If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains water. This allows mold to easily grow below its surface. Bacteria(细菌) can also grow along with it. It’s easy to remove mold from hard food. The mold can’t grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold to remove it. It’s OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away.
④ But some kinds of mold have good influence. Some kinds of mold can be used to make food. For example, penicillium(青霉菌) can be used to make many different kinds of cheeses, such as blue cheese. These cheeses are safe to eat and they’re quite delicious as well.
