How do you decide if someone is smart? One way is to find (A)______the person’s intelligence quotient(智商), or IQ.

A 12-year-old girl recently took an IQ test. People found that her IQ is higher than Stephen Hawking’s!

Rajgauri, an Indian girl studying in England, scored 162 in the famous Mensa (门萨) founded in England in 1946, is the largest and oldest high IQ society in the world. Hawking got a score of 160. Although Einstein never took the test, (B) Hawking’s, his, said, as, would, same, experts, score, the, be.

Then, what does having a high IQ mean? Will those with a high IQ surely become the next Einstein on Hawking? Not necessarily. Most IQ tests, including the Mensa one, language and memory. (C)______, (D)they don’t test your creativity or interest, either. Also, a lot of things can affect one’s IQ score, including stress and how familiar(熟悉).

A Mensa expert said that good habits, willpower and a strong work ethic(职业道德) are just as important as intelligence.“If you don’t develop those other qualities, you can waste a smart IQ.” she said.

Do you drink milk every day? We all know that milk is good for our health. But is that the whole? Let’s take a closer look!

Milk might be one of the best things we can drink. It has a lot of nutrients (营养物质) to help children grow. It’s rich in calcium (钙) and vitamins (维他命). Calcium gives us strong bones (骨骼). Doctors say that milk is also good for our teeth and heart. And a glass of warm milk helps us get a good night’s sleep. Milk is great!

However, some studies show that milk may cause some health problems. For example, drinking a lot of milk (three or more times a day) may make children obese (肥胖的), Live Science reported. Also, milk might not actually make our bones stronger. Scientists found that some people who drank more milk also had more broken bones.

So should we still drink milk? Milk may not be a super food. But it does give us a lot of nutrients. Drink milk if you like it, but not because you think it is the best thing for your health.

Our world is in danger. We must do something to protect the environment. What are the main problems we face?

The greenhouse effect

When we burn fuels such as petrol and coal, a gas called CO₂ is produced. Too much of this gas pollutes atmosphere, and causes it to keep in too much heat. As a result of the greenhouse effect, the earth’s temperature is increasing. This causes sea level to go up, and in the future may cause cities to disappear.

Cutting down forests

Every year, we destroy nature by cutting down huge areas of forests. This makes the greenhouse effect worse because trees take in CO₂ and give out O₂. Cutting down trees also destroys the homes of the animals that live in our forests, and causes the surface of the soil to be easily destroyed by rain. This can result in floods and even more damage to the environment.

Bad habits

Many of our habits cause pollution. People often use things once and then throw them away, or leave them on the ground as liter. This creates tons of rubbish and pollutes our land and seas.

In order to protect the environment, we need to take proper action. Chinese government has made laws and rules about dealing with the waste. We are getting serious about our bad habits now. We should only buy and use products friendly to the environment. We should also recycle as many things as possible. To reduce air pollution, we can take the bus or subway instead of driving.

If we just learn to live in new and different ways, we can make a difference.

When Cash Daniels was given “The Conservation Kid” for his efforts to protect the environment in 2021, he was only 12 years old. He got interested in environmental problems a few years ago, when he found plastic on a beach. It got him thinking about the influence that plastic pollution has on the environment, especially on rivers and oceans.

In his research, Cash found that rivers are at the heart of the problem. According to a 2021 report from Science Advances, far more rivers than thought—at least 1, 000 of them—are carrying large number of plastic into our oceans. This hit close to home for Cash. He lives in Chattanooga, Tennessee. The city sits on the Tennessee River, one of the most polluted in the world.

This information motivated（激发）Cash to take action. He made it his mission to clear litter from public spaces and local waterways.

At first, he and his parents worked together to pick up litter near the Tennessee River. But Cash soon realized that he would need more help.

So he organized community cleanup outings. Finally, he and other volunteers removed more than 11, 000 pounds of litter from the river.

Cash has also teamed up with businesses to recycle aluminum cans （铝罐）. So far, he has recycled more than 2, 000 pounds of them. The money he earns from that supports river protection efforts.

Cash enjoys getting people, especially other kids, involved in environmental activism. He wrote a children’s book called One Small Piece, which he has read to students in his community. In it, he spent much time explaining the problem of pollution and how streams, rivers, and oceans are interconnected.

In January 2022, together with his friend Ella Grace, he founded Cleanup Kids. So far, The Cleanup Kids has had more than 50 members across the US, Canada, and Australia. The group encourages children to pick up and recycle litter, as well as to raise awareness（意识） among young people to understand how much human life depends on the nature. The goal for the young volunteers is to collect 1 million pieces of litter by the end of 2022. “Kids may be a small percentage of the population,” Cash says. “But they are 100% of the future.”

【推荐1】Have you ever taken PE classes with face masks(口罩), running, jumping, throwing? If so, that can be dangerous and risky.

When doing exercise or sports, breathing is faster and harder than at rest. It increases(增加) the risk of passing the disease on. As a result, people are considering having masks on, others may follow suit(跟着做), especially during the outbreak of COVID-19.

We know that exercise leads to faster and harder breaths, a mask makes it harder to take in enough air when you perform at the highest levels. At low to moderate-intensity(中低) exercise, effort will feel a bit harder than normal with a mask, but you still walk comfortably. The challenge appears to be more during heavy exercise, like rugby or football, taking in air at rates(率) of about 40-100 litres per minute.

When we do heavy exercise, our muscles(肌肉) produce lactic acid(乳酸), which causes the sense of burning. It is then turned into CO₂ and stored. But what happens if the CO₂ is stopped by the mask? As you move from moderate to heavy exercise, you may be re-breathing CO₂. It can be bad for your health. There may also be less oxygen in the recycled air. It could be like exercising at highland. So it is important to understand the limits(限度) of heavy exercise with masks.

【推荐2】Please Touch Museum is a special museum where people can touch everything. It is in Philadelphia, the USA. The museum was built in October, 1976. It is a very big and interesting museum. It is popular among children, especially(尤其) among children under the age of 5.

There are many things you can play and touch in the museum. In each area, there are different activities for children to do. Come with me to enjoy it!

Walking Piano

There’s a super big piano on the ground. Do you want to play it? It’s very easy. Just walk on the piano. Then you can play beautiful music.

Alice in Wonderland

You can go down along the rabbit hole like Alice did in the famous story. There you can meet the queen（王后）and Mr. Rabbit. You can even have tea with them. That would be a fantastic trip!

Flight Fantasy

Do you want to make your own rocket (火箭)? Please come to Flight Fantasy. You can also dress like an astronaut and get into a rocket. You can have a chance to feel the sky. That is a special experience for every child.

Here is some advice can help you make your parents be healthy.

★ Make an idea list (清单). Is there an unhealthy thing you’d like to see them stop doing, or do less often? Is there a healthy habit—like exercising or eating fruits and vegetables—that you’d like to see them do more often? __1__ And don’t forget to add relaxing more and getting more sleep—two great, healthy ideas for patents and kids!

★ Practice how to say it. Changing can be hard. And it’s not always easy to hear that someone you love thinks you need to do it. So you’ll want to bring up this topic in just the right way. __2__ Pick a time when everyone is relaxed and there’s time to talk.

★__3__ You might like to go for a walk after dinner, help make a healthy meal together every Sunday, or do a few more chores if it helps your parents feel less stressed.

★__4__ Both you and your parents should decide on which steps to take next.

Cheer them on! Encourage your parents as the family starts making changes. A hug or a homemade card can encourage them to keep going down the healthy road.
