Grapes can be consumed in many ways. It can be either eaten raw, consumed in a juice form or used to prepare wine. During autumn, you will find different kinds of grapes in the market. As it is the main season of grapes, the amount of consuming this fruit is very high.
Although grapes are tiny in size, it has numerous health benefits. A lot of people are unaware of the health benefits of grapes. For example, drinking grape juice is one of the easiest ways to treat acidity. Moreover, the fruit juice is also a healthy drink for those who are on a diet.
Grape juice is loaded with nutrients, vitamins and mineral which keep us fit. For example, drinking grape juice is one of the traditional ways to cure a painful headache.
It would be interesting to know that grape juice is good for skin as well. Drinking a glass of grape juice every day helps get a clear and perfect skin naturally.

3 . There has long been a view that in ancient times men were the hunters-out getting the neat — while women were gatherers-searching for fruit, vegetables and wild plants.
However, this stereotype has been overthrown by an archaeological discovery. Scientists found the remains of a teenage girl, who lived around 9,000 years ago, at a site in Peru alongside a hunting toolkit(工具箱).There was a knife and fakes(薄片)of rock for removing internal organs(内脏), and other hunting tools.
"It took a strong case to help us recognize that the archaeological pattern indicated actual female hunting behavior," said Randy Has, he lead author of the study.
The remains were recovered in 2018 when an archaeological site was being excavated(挖掘). Actually, Haas' team didn't plan to study female hunters. They found six bodies in a burial pit, a site 3,925 meters above sea level, on a windy plateau in southern Peru. The researchers used a new method to determine the sex of the found bones. The technique analyzed a protein in the remains' tooth enamel(釉质)to tell their gender. It turned out that the remains with an impressive hunting kit belong to a female.
According to the study and previous records of 107 other burial sites throughout North and South America, the team thinks that between 30 percent and 50 percent of big-game hunters who lived more than 10,000 years ago in the Americas could have been women.
However, some people think the hunting tools could have been placed there for symbolic or religious reasons, so the girl might not be a hunter.
In response, Haas pointed out the 9,00-year-old tomb contains a wide variety of tools-some are very rare, some are common — so this suggests that these tools were not some kind of sacrificial(献祭的)offering. Rather, they were the object that individuals used regularly.
Haas said this debate has great significance in today's world. "This insight-for me at least-stresses that many of the gender inequalities we see today do not have a biological basis," he said.

4 . If the world wants to control global warming, water shortage and pollution, then we all need to welcome “flexitarian” diets, say scientists.
This means eating mainly plant-based foods, and is a key step toward an environment friendly future for all in 2050, they say. Food waste will need to be halved ad farming practices will also have to improve, according to the study arid out by the Intergovernmental Panel on Climate Change (IPCC). Without action, the influence of the food system could increase by up to 90%
The authors say that he present food industry has a number of considerable environmental effects including being a great driver of climate change, using up freshwater and causing pollution through heavy use of chemical fertilizer. The study says that thanks to the population and income growth expected between 2010 and 2050, these effects could grow between 50-90%. This could push our world beyond is planetary boundaries, which the authors say represent a “safe operating space for humanity and the international community”.
However, the study finds that no single solution will avoid the dangers, so a combined approach is needed. So when it comes to climate change, the authors looked at what they called a “flexitarian” diet.
“We can eat a range of healthy dies but what they all have in common, according to the latest scientific evidence, is that they are all relatively plant-based,” said Dr. Marco from the University of Oxford. “You can go from a diet that has small amounts of animal products (some might call it a Mediterranean-based diet; we call it a flexitarian diet) over to a vegetarian(素食的) diet—we tried to stay with the most traditional one of these which in our view is the flexitarian one, but even this has only one serving of red meat per week.”
If the world moved to this type of diet, the study found that greenhouse gas emissions(排放物) from farming would be reduced by more than half.
Dr. Marco says that all measures combined can result in keeping both the planet and people healthy.

In addition to its portability, the kayak also has the high performance capability of a professional kayak. It consists of five independent air chambers(气囊). Even if two of them don't work, the kayak floats are enough for sports enthusiasts to return to the shore safely.
Myopia prevention glasses
Frequent exposure to electronic devices has led to poor eyesight among teenagers. To address this issue, French company Essilor released a myopia(近视) control lens.
With the help of advanced technology, the lens can create a beam in front of the retina(视网膜) to slow down the increase of the eye axis.
“After more than two years of clinical research, the results show that the lens has an obvious effect on slowing down myopia progression in children,” said La Fan, a professor at Eye Optical Hospital Affiliated to Wenzhou Medical University.

6 . A dear friend sent me a letter and handmade card in the mail today. On the outside of the card was a cutout picture of a hummingbird(蜂鸟) in mid-Night. With is wings, it flew deep into a flower Below. it was a quote by Russian writer Fyodor Dostoyevsky: “The world will be saved by beauty.” I smiled with both my face and heart when I saw it.
Looking at it reminded me of all the beauty in this world. I thought about the beautiful green forested mountains of my home. I thought of the fields of summer wildflowers blessing the world with their colors. I thought of the blue oceans that stretched from horizon to horizon. I thought of the sunsets in the desert wit their deep, rich reds and glorious golds. I thought of the endless variety of animals: green hummingbirds, white polar bears, red birds, gray wolves and blinking lightning bugs. I thought of the silver moon smiling down from the sky surrounded by a sea of stars.
Yet, I knew that it wasn’t the beauty of any of these things that would save the world. It was instead the beauty of human souls filed with light and love. It was these souls so full of love for each other and for this world that would save our planet. It was this love working through people that would make this world the place it was truly meant to be in the end.
My friend who sent me the card is one of these people. She, her husband and her family are going through so many struggles right now. Still, she continues to share her love and make this world a better place every single day. She continues to work to save our home by giving it the beauty of soul. She continues to shine her light.

7 . When I was four years old，I got stung(螫) by a bee－twice in one week！After that，I had a fear of bees.That's when my parents suggested that I learn about bees instead of being frightened. I read picture books and watched videos about bees，and I learned that bees help make the food we eat because of their pollination(授粉). Take pizza，for example. If we didn't have bees to pollinate tomato plants，we wouldn't have tomatoes for sauce. And we wouldn't have cheese without pollination，either.
The bad news is that bees are struggling to survive. Many are dying. Some scientists think it might be because of chemicals that are used to kill other insects. What would happen if there were no more bees? I wanted to help. I thought, “What if I make lemonade，sell it，and raise money to help bees?” I talked to my grandmother Helen. She gave me her recipe(调制法) for lemonade. It came from a cookbook from 1940.
I added honey to her old recipe. That way，I could sell the lemonade and donate some of the money to groups that are helping to save bees. I could also support local beekeepers by using their honey in my product. And I would be educating others on the importance of bees and helping to save them.
My dad showed me how to work out what supplies I needed to buy. At first，I sold lemonade at a stand at a kids' business event. But I wanted to help bees all year round. We talked to a pizza place near where I live. They said they wanted to sell it. Now more than 30 stores sell it，too. This year we sold about 140,000 bottles. I love helping to save bees. It's the sweetest feeling ever.
