【題目】An oval-shaped (橢圓形) structure, which is believed to be 121meters across, is shown in a picture of Antarctica.

Some say the structure is evidence that human civilization once lived in the South Pole, while others say it may be a natural phenomenon.

“What if, in the distant past, an ancient civilization developed in Antarctica, creating splendid structures and temples there?” Peter Turney says in a post on Ancient Code.

The post says scientists first thought the discovery could be a sastrugi (雪面波紋)a natural phenomenon formed by years of battering (磨損) by strong, freezing winds and heavy snowfalls. But sastrugi are not known to form in oval shapes.

This is not the first time people have suggested there was a lost civilization in Antarctica.

Ever since last year, some people have been claiming (聲稱) that a strange pyramid in the Antarctic has appeared.

A video posted on YouTube by Third Phase of the Moon, a YouTube channel, showed a picture of a pyramid-like structure in the snow. Responses to the picture were varied, with some users backing-up the claims, such as James Jason, who commented: “Excellent report by Third Phase!I also believe things are about to get very dramatic (戲劇性的),and that is for everyone on our planet.”

Ashoka Tripathi from the University of Calcutta said the pictures showed clear evidence of an ancient human settlement beneath the ice sheet. “These are clearly characteristics of some sort of human-made structure, like some sort of pyramidal structure,” he said. “The patterns clearly show nothing we should expect from nature. We clearly have evidence of human engineering here,” John Emerson, his colleague, added.

But others were against it, such as Gordon Anderson, who said, “I have spent a lot of time on snow covered mountains—skiing down, and this looks natural to me—not man made anyway!”

Good morning, everyone. I'd like to share my ideas about books in the future to you.

I think the books will be quite different from that they are now. First of all, they will look like the pads today, but their sizes will be changeable, too. Secondly, their colors will change depend on how the surroundings change, which will be good for eye what's more, they will be very much more practical. For example, if you met a question when reading, you can immediate get an answer by “talking” with the book. In word, I think books in the future will be more useful and interested.

That's all. Thank you!
