【推荐1】Animals can laugh, too. Their “laughter” may not sound like ours, but scientists have learned that many animals make sounds and faces, just like us.

A 2021 study by Sasha Winkler and Greg Bryant found that at least 65 animals make special noises when they are playing “When dogs play,they like to bark really heavily. Monkeys like to whistle(吹口哨), and even birds will make short high sounds.” Bryant said. “The animals are telling each other they are having fun.”

Playing can look a lot like fighting among animals, so these play sounds help show that an animal means no harm. Bryant said, “They look like attacking someone, but they don’t really want others to think so, because others might be afraid and even attack back!” These sounds help to show that animals are not attacking when playing.

But it’s not just about the sound of a laugh. In 2022, scientists Marina Davila-Ross and Elisabetta Palagi looked at the faces animals make during play. Some animals,including chimpanzees, lions and African wild dogs, open their mouths wide in a laughing expression(表情)when they are having fun. Researchers think this might come from the movements during playful biting (咬).

Animals’ play sounds and laughing faces can help them to know each other’s feelings and play with each other better. According to Davila-Ross, this research also helps us to empathize with animals’ feelings more.

【推荐3】Hooray! Here comes 2022, the Year of the Tiger! Let’s learn more about tigers!

For Chinese people, the tiger is the king of all the animals. It is a symbol of bravery and power. You can often see pictures of tigers on the walls of people’s houses. Chinese parents like making tiger hats and shoes for their children. They are in the shape（形状）of a tiger’s head. Parents think that their kids will grow to be as strong as little tigers.

You must be surprised to see the tiger paintings in Japan, because most of them look like big cats! In old times, Japanese people loved Chinese paintings a lot. But there were no tigers in Japan, so the artists painted the pictures with their imagination!（想象）

In western countries, tigers are also thought to be powerful animals. There are lots of cool sayings in English. If your father is very strict with you and always pushes you hard, you can call him a “tiger father”. If someone looks strong or dangerous, but is not really so, then he is a “paper tiger”. If you want someone not to be angry and calm down（冷静）, you can say to him “Easy, tiger!”.

2022, the Year of the Tiger means a lot to every one. Enjoy your day and work like a tiger! Never take a job without thinking twice, or you may ride a tiger!

【推荐1】Being thankful and expressing it to others is good for our health and happiness. It also helps us build trust and closer relationships with the people around us.

These benefits have mostly been seen when two people are involved: one person gives thanks and the other receives thanks. Now, a new study suggests that expressing gratitude (感谢) not only improves one-to-one relationships, but could bring whole groups together—inspiring (激发) a will to help and connect in people who simply see an act of gratitude.

In this study, Sara Algoe and her team ran several experiments to find out how seeing gratitude influences people’s feelings toward the thankful person and the person who is thanked.

In one experiment, participants (参与者) were tasked with reading a movie review draft and underlining eye-catching parts for the reviewer’s benefit. First they saw an example. Several lines of text were underlined, as the task required, but many mistakes were also corrected, showing effort that went beyond the task. Some participants could see a handwritten note from the reviewer saying, “Thank you so much for catching those mistakes!”

Afterward, participants underlined parts in another article by the reviewer. Then researchers counted how many mistakes participants corrected, and asked them how much they might like to be friends with the reviewer.

The results showed that participants who had seen a note of gratitude were more willing to correct mistakes and help out, and more likely to want to become friends with the reviewer, than those who hadn’t.

Algoe and her team also discovered from other survey questions that participants wanted to help and connect with the person receiving the gratitude. “That’s because receiving gratitude marks you as a person who is effective at being supportive or helpful,” says Algoe.

These findings show that expressing gratitude not only strengthens the relationships between the people involved but also influences the people who see it in ways that could reverberate throughout a group. If people in a group notice others’ good acts and thank them for their kindnesses, the whole group could be encouraged to be kinder to one another.

Does this mean we should all express gratitude more often? Yes. We can give a hug, bring a gift of flowers, or just say thank you. Gratitude expression seems to be a special kind of emotional experience that is great for building relationships.

【推荐2】A Dry Ice Experiment

Did you know that carbon dioxide sent out by dry ice can actually put out flames? Encourage your kids to try this simple experiment. It’s suitable for young kids in first and higher grades, so long as there is plenty of adult direction. The experiment takes no longer than five to ten minutes.

Materials

*Three candles

*A lighter

*A glass or bowl

*One-half cup of water

*A block of dry ice (the size does not matter)

*Dry ice gloves

Instructions

1. Light the candles with a lighter and fix them in a glass or bowl.

2. Put on your gloves.

3. Pour one-half cup of water into the glass or bowl.

4. Place a piece of dry ice into the glass or bowl with water, and watch the dry ice vapor (蒸气) begin to rise.

What’s Happening

When you add dry ice to water, it produces carbon dioxide, the gaseous form of dry ice. Since flames need oxygen to burn, the flames go out once the oxygen is taken over by carbon dioxide.

Safe Handling Instructions

Because dry ice is so cold, it isn’t safe to touch it to your skin or put it in your mouth. Always use insulated (隔热的) gloves when handling dry ice to avoid ice bite and other injuries to your skin. If you put dry ice into a bottle, avoid capping the bottle as the pressure from dry ice can push the cover off forcefully.
