【推荐1】Engineers in the US have created a group of robots that are able to work together to overcome obstacles（障碍物）. “When ants collect or carry objects, if one comes upon an obstacle, the group of ants work together to overcome that obstacle,” explained Dr. Ozkan-Aydin, who led the research. “If there’s a gap（裂缝）on the road, for example, they will form a bridge by holding together so the other ants can travel across. That is the inspiration for this study.”
Ozkan-Aydin and her workmates 3D-printed a group of four-legged robots. They have touch sensors（传感器）at the front and back, so that they could sense and connect with other robots in the group. The robots were under tests of finding their way over different surfaces, including grass and rocky ground. Ozkan-Aydin also made some obstacles for them to climb up. If a robot couldn’t find its way out, it would send a signal（信号）to the other robots. Then, they would hold together with their touch sensors.
Ozkan-Aydin said this technology could be used in the future to make groups of robots to help look for people in accidents, carry things over rocky surfaces and do research in dangerous places. However, for that to become true, she says battery（电池）technology will need improving so that the robots can work for up to 10 hours without running out of power.

Chinese Puzzle Nowadays, a large number of mobile and computer games come out one after another.

| The Luban lock was first created by the well-known Chinese woodworker Lu Ban during the Spring and Autumn period. It was said that Lu used six wooden pieces to make it to test his son’s cleverness. It requires one’s sense of space to move the six pieces apart. Now, there are Luban locks made up of nine or more pieces. |
| The tangram has seven pieces in different shapes. For each puzzle, players need to use all the pieces to make a shape, like an animal, a person, a plant or some other things. To do it, they have to know about space, shapes and sizes. The game was popular in the Ming and Qing dynasties. In the 18th century, it was brought to the West and became popular. |

【推荐3】Do Encyclopedias Know Everything?
LONG BEFORE Wikipedia or Encyclopedia Britannica (《大英百科全书》), there was Pliny the Elder. He was a first-century Roman researcher. His assistants (助理) read to him while he ate dinner and while he bathed. All the while, Pliny took notes. He even considered walking a waste of time. His assistants carried him around Rome in a chair while he read.
All of this was preparation for his Historia Naturalis (《博物志》). The book was published in A.D. 77. It is considered the oldest surviving encyclopedia on Earth. There are 2,500 chapters. They cover everything from mice to Mars.
“No Roman author has completed such a project,” Pliny proudly announced. Unluckily, two years after publishing (出版) the encyclopedia, he died in a natural disaster.
Accidents can hardly be avoided (避免). However, they can be recorded. Editors of encyclopedias, like Pliny, organize the knowledge of our world. Like a valuable gift, the books pass through the ages. They begin their lives as a tool and end them as a historical record.
Therefore, in my opinion, an encyclopedia is not just a record of what its editors know. It’s also a record of what they don’t know.
Pliny was wrong when he said there were seven planets, including the Sun and the Moon. He was wrong, too, when he said Africans were black from being burnt by the Sun. After all, Historia Naturalis is a book edited by a Roman thousands of years ago. These were all he truly knew.
Similarly, both Wikipedia and Encyclopedia Britannica have some incorrect information. Even the biggest encyclopedias only represent what their editors know.
“The task of editing an encyclopedia can never be completed,” said Roger Lewinter, an American researcher. Encyclopedias can’t record all of the human knowledge but just some of it. They are always waiting for someone — you, perhaps — to improve them.

| A．In A.D. 79. | B．In A.D. 77. | C．In A. | D．75. D. In 77 B.C. |
| A．We should destroy Pliny’s encyclopedia because it contains too many mistakes. |
| B．Modern encyclopedias — such as Wikipedia — have fewer mistakes. |
| C．In the biggest encyclopedia, we can find all of the human knowledge. |
| D．In all encyclopedias, there is some incorrect information. |
