【推荐1】You may drink bottled water when you are thirsty. But plastic bottles are bad for the environment. Is there a way not to use plastic bottles to hold water?

Try the Ooho bubble（泡状物）. It is a small ball of water. The water is in a soft container. People use it instead of a plastic bottle. It has no color, no smell and no taste. It is made from seaweed（海藻）and is safe for people to eat.

You can make a hole in the container and drink water from it. Or you can just put the whole ball into your mouth.

Three creators from a college in London made the Ooho bubble. It is good for the environment. And people can only spend 0.14 yuan buying one ball. It is much cheaper than a bottle of water, so many people like it.

But there are still a lot of problems to solve. For example, each water ball doesn’t hold much water. People may have to drink a lot of them if they are very thirsty. Or some may feel it’s not clean to hold the water bubble with their hands.What do you think about it?

【推荐2】If you have a dog, you probably feel a strong bond (纽带) with it. A recent study found that this bond may not only be important to kids, but also be important to dogs.

Researchers at Oregon State University studied the relationship between kids and dogs. To do the study, they recruited (招募) 30 young people aged 8 to 17, who have dogs to do an experiment. The kids were asked to bring their dogs to an empty room. In the room, a kid was asked to walk around the huge space, sometimes stopping or changing the direction. “And the dog was left to do whatever the dog wanted to do.” says Monique Udell, one of the study’s authors.

But most of the time, the dog didn’t do any of those things. Instead, it stayed close to its owner and moved similarly to its owner. The dogs did this far more often than you would expect them to do it by chance.

What does this mean? Udell explains that this is a dog’s way of building a relationship with a human, “Dogs always stay close to kids, even though adults are usually the ones who feed and care for them. The kid may play a sibling (兄弟姐妹) role in the life of the dog,” Udell says. “This shows that the relationship between kids and dogs is of great importance to the dogs.”

So far, Udell’s team’s study has just focused on dogs. Udell wonders if the animal-human bond is important to other kinds of pets as well. Researchers say that more studies will be done.

①Every time you feel uncomfortable, you can check yourself by taking your temperature. So, what’s the average (平均的) human body temperature? Well, if you say 37℃, maybe you are wrong. It turns out that the average body temperature has dropped in the past one hundred and fifty years, according to a new study.

②“Everybody knows that our normal temperature is 37℃, but it is wrong,” said Julie Parsonnet, a Stanford University medical professor.

She and her team looked at medical data (数据) from three different time periods: 1862 to 1930, 1971 to 1975, and 2007 to 2017. Comparing the data, they found that body temperature has dropped by about 0. 02℃ every ten years. So what’s the new body temperature? It’s 36. 6℃, says the study.

③As for the reason, one possibility is that living in temperature-controlled buildings has changed our bodies. They don’t need to work hard to keep the temperature normal. Another is less inflammation (炎症) in people’s bodies. Inflammation makes your body use more energy, which increases body temperature. Progress in medical treatments (治疗) and improved standards of living have led to less inflammation in people’s bodies compared to 200 years ago. No matter what the reason is, our bodies are changing.

④Another interesting fact is that men and women have different ideas about what the comfortable temperature is. According to one study, women are comfortable at a temperature of 24—25℃, which is 2. 5℃ higher than the temperature preferred by men. What’s more, studies have shown that as the temperature drops, women’s blood runs slower than men’s.

⑤ The human body may have changed over the past hundred years, but one thing that has not changed is that men and women have different feeling about what temperature is comfortable.
