Buried deep in the ruins of the Shang Dynasty, 【小题1】 (specific) in Anyang City of Henan Province, bones of the rhino (犀牛) were found.

A collection of archaeological evidence has confirmed the 【小题2】(exist) of rhinos in ancient China. The animal【小题3】(distribute) across China’s Central Plains, 【小题4】 Chinese civilization originated.

Nevertheless, the rhino was no longer wandering in the region after the Han Dynasty. One explanation is that it was the colder climate of Northeast Asia that saw the creature【小题5】(appear) from the pages of history. However, Zhou Yu, the writer of History of Chinese Armor (盔甲), offered up【小题6】 explanation: the crafting of armor.

Armor was originally made of bamboo but the material possessed limited【小题7】(defend) capabilities. Leather armor later became popular during the pre-Qin period. Zhou’s book【小题8】(read) that the rhino’s thick skin was a primary material for the creation of warriors’ armor. Many ancient accounts recorded the killing of rhinos and 【小题9】(turn) their skin into protective covering. “The huge demand 【小题10】 rhino skins might have caused the animal’s disappearance or at least its migration from the Central Plains to the southwestern regions,” Zhou told Beijing Review.

Four years ago, Danielle Crull rescued a stray cat from a forest in Pennsylvania. Now, the cat, Truffles, is changing hundreds of lives by helping children 【小题1】 have eye problems feel more relaxed about wearing glasses. Truffles, famous for her charming glasses, works alongside “her mom”, an optician. When kids come in, they are often terrified of anything 【小题2】(come) near their eyes. That's when Truffles comes to the rescue. “With little ones crying, Truffles comes out 【小题3】 I put glasses on her. They immediately slop crying and put their own glasses on.” Crull said, Truffles is literally magical with little kids.

Forrest, a biologist, uses a metal clicker to count every penguin he sees. It’s not easy. He is part of a team 【小题1】 (work) on the Antarctic environment. The survey will help scientists better understand the Antarctic environment. Over the years, the number of penguins in Antarctic 【小题2】 (go) down. Scientists say climate change is making the ocean warmer. “Penguins give us an idea about what is going on in the ocean around us,” Forrest says. This year, robotics engineers fly a drone to help him record each colony’s 【小题3】 (locate) and size.
