China’s first artificially-bred(人工繁殖) second-generation finless porpoise (江豚) is named Hanbao. The name’s meaning is divided 【小题1】two parts: “han” means it was born in Wuhan, Hubei province,【小题2】 “bao” means little baby in Chinese. As the fattest porpoise at a local Baiji dolphin museum in Wuhan, Hanbao 【小题3】(weigh) about 70 kilograms.

Finless porpoises, also called “smiling angels”, have become 【小题4】 sign of the health of the Yangtze River ecosystem. To prevent their extinction, finless porpoises have been bred artificially. Despite efforts to protect the finless porpoise for over 40 years, 【小题5】(it) numbers continued to fall. However, a scientific survey of Yangtze finless porpoises 【小题6】(carry) out on Oct 25 indicated the species’ recovery. The change is owed to a 10-year fishing ban on the Yangtze River, 【小题7】 began on Jan 1, 2021 and the Yangtze River Protection Law that came into effect two months later.

Because of these measures,【小题8】(region) along the Yangtze River have relocated their chemical plants, restored wetlands and reorganized the sailing route. All these efforts 【小题9】(ultimate) improved the river’s ecological environment, 【小题10】(help) to breathe life into the finless porpoise species.

I'm not sure 【小题1】 is more frightened, me or the female gorilla(大猩猩）that suddenly appears out of nowhere. I'm walking on a path in the forest in the Central African Republic. Unexpectedly, I'm face-to-face with the gorilla, who begins screaming at 【小题2】 top of her lungs. That makes her baby scream, and then a 400-pound male appears. He screams the

【小题3】(loud)of all. The noise shakes the trees as the male beats his chest and charges toward me. I quickly lower myself, ducking my head to avoid 【小题4】(look) directly into his eyes so he doesn't feel【小题5】(challenge).

My name is Mireya Mayor. I'm a 【小题6】(science)who studies animals such as apes and monkeys. I was searching 【小题7】 these three western lowland gorillas I'd been observing. No one had seen them for hours, and my colleagues and I were worried.

When the gorillas and I frightened each other, I was just glad to find 【小题8】(they) alive. True to a gorilla's unaggressive nature, the huge animal 【小题9】(mean)me no real harm. He was just saying: "I'm king of this forest, and here is your reminder!" Once his message was delivered, he allowed me 【小题10】 (stay)and watch.

Scientists have exposed that around two-fifths of the world’s plants are in danger of extinction. A top scientist studying plants, Professor Alexandre Antonelli, said, “We are living in 【小题1】 age of extinction. It’s a very 【小题2】 (worry) picture of danger and need for immediate action. We’re losing the race against time【小题3】 species are disappearing   【小题4】 (fast) than we can find and name them. Many of them could hold important clues for solving some of the most pressing 【小题5】 (challenge) of medicine and even perhaps of the new and current diseases we are seeing today.”

There   【小题6】 (be) positive signs in the past few years. More than 4, 000 species of plants and fungi (真菌) were discovered in 2019, among 【小题7】 are possible future foods that could be a lifeline to millions of people on the earth suffering from being poor and unsafe food. Professor Antonelli stressed strongly the 【小题8】 (important) of protecting these and all plant life on the earth. He said, “We would not be able【小题9】 (survive) without plants and fungi—all life depends 【小题10】 them. Every time we lose a species, we lose an opportunity for humankind.” Leading scientists will demand world leaders act against biodiversity loss.
