A kind of beer made from ancient yeast(酵母) up to 5, 000 years old has been shown to the public by Israeli researchers.

These researchers got six types of yeast from the old pottery(陶器)discovered in the Holy Land. The beer is believed to be similar to drinks enjoyed by the Pharaohs(法老) of ancient Egypt.

"I remember that when we first brought out the beer, sat around the table and drank, l said," We'll be good, or we'll all be dead in five minutes, '" said Aren Maeir, an archaeologist from Bar-Ilan University. "We lived to tell the story. "

In the past, beer was a basic thing—like bread—enjoyed by all the people in Israel. Since there was always a risk of water pollution, fermented(发酵的)beer and wine were considered much safer to drink.

Ronen Hazan and Michael Klutstein，two biologists at Hebrew University, came up with the idea of creating beer by using old yeast. With the help of beer expert Itai Gutman, the team used modern techniques to create a drink similar to wheat beer(小麦啤酒).

"The greatest wonder here is that the yeast has lived for thousands of years—just waiting to be dug and grown. "Dr. Hazan told reporters. "By the way, the beer isn't that bad. "

The team says they hope to make more beer by using ancient techniques instead in the future.

Do you know where this photo comes from?

Well, it ( take ) on Easter Island(复活岛). The island is in the south of the Pacific, and it is very difficult tourists to find its position. It is

covered with  (hundred) of huge stone statues(雕像). Each of them weighs several tons and some are more than 30 feet tall.nobody knows who built these statues and why and how they got there.

It(seem) that the statues have been made out of the top edge of a volcano(火山) on the island. A statue have been rolled or dragged down to the foot of the volcano. Then, it was stood upright and ropes were tied around it, which was made  ( act ) as a pulley (滑轮). Over a period of months, a statue could be walked for miles down to the ocean. In the end, it was (place) in line with other statues, all of them looking towards the center of the island.

Today, Easter Island(remain) one of the most famous historical places. It is likeopen-air museum, showing a fascinating but unfortunately lost culture.

l think nothing else in the world is than love.

You may think of museums as dusty collections of old objects, but modern museums are different. They are landmarks and showcases of local culture, offering visitors insights (洞悉) into the past.

The National Museum of Qatar, which opened on March 28, 2019, is the latest example.

The building's interlocking structure of steel, glass and fiber concrete makes people think of the petals (花瓣) of a desert rose. These "roses" are actually crystallized (结晶的) sand, found just under the desert's surface. "It's surprisingly complex and poetic," the designer Nouvel told UK-based design magazine Dezeen.

This pioneering design also makes the building energy -efficient. They form a sunscreen and cast (投射) protective shadows when the sun hits the building from east or west. "I want to build a structure that keeps in line with the condition of the place, to ensure that it offers maximum (最大化的) protection from the sun and save energy," Nouvel said.

Apart from its unique shape, the museum also includes Qatar' s tradition of both nomads (游牧民) and fishermen. It's committed to preserving and showing the wooden dhows (阿拉伯三角帆船) that were once Doha's lifeblood. These boats enabled fishing, trading and the collection of precious pearls. And visitors can see over 1.5 million of them on the hand-embroidered Pearl Carpet of Baroda, the most extravagant (奢侈的) carpet ever, in the museum.

The museum also seeks to redefine(重新定义) the role of cultural institutions. It's hoped that visitors will not only observe the exhibitions but also immerse (沉浸) themselves in Qatar's history. For this purpose，it features a multilayered , 360-degree environment. For example, on the path to the Gallery of Life in Qatar， viewers see open markets, camels carrying goods, and wealthy pearl traders drinking tea and doing business.

"It creates a dialogue between the past and the future," according to a museum press release. "The scheme will give voice to Qatar's heritage (遗产) while celebrating its future."
