Gout is a bone disease. When uric acid (尿酸) builds up in someone’s body, it can be bad for bones.
T. rexes were once the scariest meat eaters on Earth. A T. rex could weigh (重) as much as two African elephants. What did T. rexes eat? Well, the answer might be “Anything they wanted”. T. rexes ran fast and they had sharp teeth. So they always won the battle against other animals.

Remember that breakfast is the most important meal of a day. If you don’t have time to sit down and have a healthy breakfast, try vegetable juice before you go to school. This is much better than coffee.
It’s a good idea to eat less salt. Food like hot dogs have lots of salt in them. So give them up.
You should also stay away from food with much fat (脂肪). You can eat vegetables, fruit, fish and chicken. They are healthy for you and help you relax as well. For example, you can eat chicken hamburgers instead of beef hamburgers.

It took place at Huntington Beach, California, US. For the dog’s safety, they must wear life vests (救生衣) while in the water. They get scores after riding on five waves during a 12-minute surf. The event is free to watch. |
 | What are these people doing? They are helping a stranded (搁浅的) humpback whale go back to sea. On 3 October 2021, people found the whale on a beach near Buenos Aires, Argentina. It was the second stranded whale found there. The first was found one day before. One is a 9.8-metre-long female whale. She weighs about eight tons. The other is a smaller male. About 30 people came to save them. They used a digger (挖掘机). |

【推荐2】Bees are famous for making honey(蜂蜜), but did you know that they have another skill too? They can tell the difference between works (作品) of art. A bee knows French painter Monet’s paintings from Spanish artist Picassos.
This discovery was made in late October 2021. Scientists at the University of Oueensland (UO) Australia did an experiment to find out how bees find food. The results also tell us something about how humans respond (作出反应) to art.
Judith Reinhard, a scientist, of the UQ said bees are cleverer than we realized. “Although their brains are small, bees have a well developed ability for understanding visual (视觉的) information,” she said.
The scientists put sugar in a hole behind one of two paintings of Picasso and Monet. They then sent bees to find the sugar. They had to pick the right painting to get the food. The bees could tell from five different pairs of paintings.
Scientists said that the bees had learned how to know the paintings “artist’s style”. They didn’t think it was because the bees were attracted by the smell of sugar. The scientists said that the human brain might use the same way to tell the difference between artworks.
Reinhard said that the experiment showed that bees do not use light, color or other things to know different artworks. They could find food even when the paintings in front of them were black and white. It turns out their brains might be bigger than we thought!

In stormy weather, we can stay safely indoors. But for birds, rain may be a matter of life and death. So, how do birds stay safe in bad weather?
Rain brings two problems to birds: being too cold and hungry. A bird’s feathers keep warm air close to its body. But if the feathers are wet, the birds will get very cold quickly. So many birds waterproof (使……防水) their feathers by using oil stored at the base of their tails. This allows them to fly in the rain for a short time. If the rain lasts for more than a few hours, birds will have no choice but to brave the bad situation in search of food. Small birds have an especially hard time in the rain. Their small bodies lose heat quickly, and the bugs (昆虫) they feed on stay out of sight.
Since rain is dangerous for many birds, it’s not surprising that more extreme (极端的) weather can be even more so. However, birds can tell when a storm is coming as they feel changes in air pressure. As a result, birds that plan to fly to other places may leave earlier to avoid the storm, while others look for shelter and try their best to survive.
Birds in cold places also have to deal with snowstorms and very low temperatures. Thankfully, birds’ bodies are made in a way that helps them stay safe. Birds’ feet are always cold, so the icy ground doesn’t hurt them. They can keep air in their feathers to stay warm, and they get ready for winter by eating more to help stay warm. As you can see, birds have a number of ways to deal with bad weather. When storm clouds gather, your feathered friends will probably be just fine.
