【推荐1】Have you ever walked into a room and felt relaxed? It could be because the walls were painted blue, a calm and peaceful color.

Sometimes colors can affect our feelings and moods. Some colors can make us feel calm and peaceful. Blue is one of these.Wearing blue clothes or sleeping in a blue room is good for our mind and body, because this color makes a good feeling. Blue is also the color of sadness, so you may say you're feeling blue when you are feeling sad. White is another calm color. You should wear white clothes if you are feeling nervous. White is also the color of purity (纯洁). Many women like to be in white on their wedding day. Green is the color of nature. It can give us more energy when we are feeling tired.

Some colors can make you feel warm. These colors can give you a happy feeling. People who live in cold climates use warm colors in their homes like orange and yellow instead of white and blue.

Orange shows joy. It can bring you success and cheer you up when you are feeling sad. Yellow is the color of the sun, so it can remind you of a warm, sunny day. Yellow is also the color of wisdom. Some people prefer this color when they study for exams. For example, they may use yellow school things. Red is one of the strong colors. Wearing red often makes us active.In short,we can try out different colors if we aren't feeling our best.

【推荐2】Horses can talk to one another.     1     They communicate with one another and with us through gestures and expressions.

Expressive Ears

When a horse turns its ears to the side or half way back, the horse is listening. It can listen with both ears.     2     If the sound is on the left, the horse moves its left ear. When a horse moves both ears back and forth, it’s paying attention to the activity around it.

Meaningful Looks

A horse that is relaxed and happy will have “soft” eyes, which look kind and round in shape. A horse that is unhappy will have “hard” eyes, which look angry.     3     When white shows around a horse’s eyes, it is frightened or anxious.

Kicking

Do horses kick only when they are angry? Not always. A horse sometimes kicks to get flies off his stomach or legs.     4     Horses in a field may also kick while they are playing.

Tails Tell Tales

A horse also talks with its tail.     5     If there are flies around, it will swish(刷刷地移动） its tail in a relaxed manner to chase(驱逐）the flies away. A horse that is playing in a field may hold its tail high, almost over its back. This shows that the horse is feeling good. If a horse swishes its tail when there are no flies, the horse is bored or impatient. A horse will swish his tail hard while they are playing.

【推荐1】Climate science has been rapidly advancing in recent years, but the foundations were laid hundreds of years ago.

In the 1820s, French scientist Joseph Fourier theorized that Earth must have some way of keeping heat and that the atmosphere may play some role. In 1850, American scientist Eunice Newton Foote put thermometers(温度计)in glass bottles and experimented with placing them in sunlight. Inside the bottles, Foote compared dry air, wet air, N₂, O₂ and CO, and found that the bottle containing humid air warmed up more and stayed hotter longer than the bottle containing dry air,and that it was followed by the bottle containing CO₂. In 1859, Irish scientist John Tyndall began measuring how much heat different gases in the atmosphere absorb. And in 1896, Swedish scientist Svante Arrhenius concluded that more CO₂ in the atmosphere would cause the planet to heat up: These findings planted some of the earliest seeds of climate science.

The first critical breakthrough happened in 1967 when Syukuro Manabe and Richard Wetherald connected energy absorbed by the atmosphere to the air movement vertically over Earth.They built a model which first included all the main physical processes related to climate changes. The predictions and the explanations based on their model still hold true in the real world almost half a century later.

The model was improved in the 1980s by Klaus Hasselmann who connected short-term weather patterns with long-term climate changes. Hasselmann found that even random weather data could yield insight into broader patterns.

“ The greatest uncertainty in the model remains what human beings will do. Figuring it out is 1,000 times harder than understanding the physics behind climate changes,” Manabe said.“ There are many things we can do to prevent climate change. The whole question is whether people will realize that something which will happen in20 or 30 years is something you have to respond to now.”

So, it’s up to us to solve the problem that these pioneers helped the world understand.

【推荐2】Many things make the 2022 World Cup one of the most unique world cups in the history of football. Let’s take a closer look at some of the most interesting facts about the 2022 World Cup that make it unique in every way.

1. Application of the new technology

Earlier this year Adidas revealed “Al Rihla,” the official match ball of the 2022 World Cup. Al Rihla translates as “the journey” in Arabic and it is designed to support the highest game speeds as it travels faster in flight than any FIFA World Cup ball created before it in the tournament’s 92-year history. The new ball features the latest Adidas Suspension System at its core, containing a motion sensor that tracks every touch of the game at a rate of 500 times per second.

2. Record number of visitors

One of the most interesting facts about FIFA 2022 in Qatar is the number of visitors expected to arrive in the country during the event. As expected, the 2022 World Cup Qatar will probably receive a record number of visitors by the time the tournament ends. The reason behind this is simple to understand. Being one of the best countries in the Middle East, Qatar is also located right in the center of the world and close to most of the countries in the world.

3. Stadium is equipped with Centralized Air Conditioning

While the World Cup is nearly impossible to hold during the summer given the fact that temperatures in Qatar can touch 50 degrees Celsius, switching to the winter slot has brought some peace. However, is the problem solved? As far as winter is concerned, even daytime temperatures during winter can be quite high. Therefore, Qatar has found a solution to this. For the first time, the country host the World Cup in an air-conditioned stadium. All eight stadiums are fully air-conditioned, providing fans with a comfortable viewing experience.
