1 . Ninety-seven percent of Earth’s water is ocean. No blue, no green. If you think the ocean isn’t important, imagine Earth without it. Fifty years ago, when I began exploring the ocean, no one realized that we human being could do anything to harm the ocean.
For me, as a woman scientist, it all began in 1953 when I first tried diving. In 1979, by using a submersible, I had a chance to reach the ocean floor which was six miles offshore and 1,250 feet down. Since then, I’ve used about 30 kinds of submarines. We need new deep-diving submersible. We need to see the undersea mountains and understand life in the deep sea. Exploring and protecting the wild ocean is my big wish.
What’s worrying us is that an ice free Arctic Ocean may happen in this century. That’s bad news for the polar bears. Additional CO2 is not only driving global warming, but also changing ocean chemistry, making the sea more acidic. That’s bad news for coral reefs and oxygen-producing plankton(浮游生物). Actually, nearly half of the coral reefs have disappeared. We’re putting hundreds of millions of tons of plastic and other rubbish into the sea. We’re blocking the ocean, poisoning the planet’s circulatory system. Most of the turtles, sharks, tunas and whales are way down in numbers. All of these are part of our life support system.
Health to the ocean means health for us. I wish we would use all means—films, explorations, the web, new submarines—and campaign to stimulate public support for ocean protected areas. My wish is a big wish, but if we can make it happen, it can truly save and restore the ocean, the blue heart of the planet. For the children of today, for tomorrow’s children: as never again, now is the time.

2 . In July 2017, Hoh Xil became a world heritage (遗产) site and there live more than 70, 000 Tibetanantelopes. Every year, pregnant (怀孕的) Tibetan antelopes migrate (迁徙) to Hoh Xil between the end of May and early June to give birth and leave with their children around August. Zonag Lake at the heart of Hoh Xil is known as the “delivery room” for the species.
About 40 female Tibetan antelopes with three young were spotted crossing the Qinghai-Tibet Railway Saturday. Experts say that in recent years, the number of young Tibetan antelopes among the migrating groups consisted of between a fifth and quarter of the population.
“In the early stage of migration, Tibetan antelopes face a high risk of falling prey to predators (盗猎者) so the number of young Tibetan antelopes is relatively small, and there may even be none,” said Lian Xinming, an associate research fellow at Northwest Institute of Plateau Biology, Chinese Academy of Sciences.
According to research, the number of Tibetan antelopes that migrate back has been rising. A total of 5, 952 Tibetan antelopes were spotted migrating in 2020, and 233 more in 2021. “This year’s migration season is expected to finish in early September. The population is expected to continue to increase,” Lian said.
Tibetan antelopes are mostly found in Tibet autonomous region, Qinghai province, and Xinjiang Uygur autonomous region. The species is under first-class state protection in China.
In the 1980s, the Tibetan antelope population declined sharply from 200, 000 to 20. 000, due to illegal hunting. It has recovered thanks to the country’s efforts to improve its habitat and crack down on poaching (盗猎).
To make sure the species go back to their habitats safe and sound, the reserve’s management bureau has staff monitor their migration. When they come over in large groups, they temporarily close some sections of the road to make way for the animals and prevent them from having interactions with humans.

3 . Wolves once ranged over most of North America. But they were nearly wiped out by the early 20th century in the neighbor U. S. by widespread hunting and trapping. Much of them were funded by government , and only a small population were hanging on in the Great Lakes region. They were put on the Endangered Species List in the 1970s, and in 1995 and 1996 the federal government reintroduced wolves to Yellowstone National Park and Idaho. But wolves still don’t have stable numbers in Colorado. Voters narrowly(勉强地)approved a proposal, giving the way for gray wolves to be reintroduced into Colorado, where they nearly died out by the 1940s.
Colorado Parks and Wildlife will lead the effort to establish a sustainable (可持续的)population of the animals in the western part of the state, beginning in 2022 or 2023. The Southern Rocky Mountains contain millions of acres of suitable habitat land that could support several hundred wolves or more, biologists say.
Those who were against the proposal admitted they lost, but the vote was close. As of Thursday afternoon, with 90 percent of the votes in, there were 1,495,523 votes for and 1,475,235 against. “Reintroducing wolves will help thin out sick animals, keeping healthy populations of deer, and thus protecting the grass and reducing erosion (土壤侵蚀). ”says Jonathan Proctor.
People in rural areas are against the reintroduction proposal, including farmers, who worry that wolves will kill their cattle. Many don’t agree to leave the question of reintroduction to voters.
Supporters point to the successful reintroduction of wolves to the Northern Rockies in the 1990s, where only one in 10, 000 cattle in wolf-occupied counties is killed by the hunters, Proctor says. The Colorado proposal will also fund a program to make up for the farm animals being killed.

Last Thursday, we have had a class meeting to discuss where to go for our autumn trip. We came up with several choices such as going boating, climbing a mountain, and going to park. Finally, we decided to go mountain climbing. The next day, we left to the mountain early in the morning. While climbing the mountain, we enjoyed the warm sunshine and the beautiful sceneries. However, when we reached the top, we were shocking to see rubbish here and there, such as bottles and banana peels. We felt sadly that many tourists didn’t take good care of nature. Soon, they started to pick them up. With all the rubbish putting in the rubbish bin, the place looked many more beautiful than before. When we came back, it was 5:30 in the afternoon. We were tired and happy.

8 . A leaked IPCC draft reports, “Widespread use across millions of square kilometers globally of tree-planting and bioenergy crops could have potentially serious consequences for food security and land degradation (退化).” In other words, more massive monocultures (单种栽培) and more bioenergy crops, fueled by more fertilizers, could damage the structure of the environmental soil and its capacity to absorb carbon.
Everyone knows that to help ease the increasing climate crisis, we need to plant new trees. It’s said that the earth could support an additional 9,000,000 square kilometers of forest, potentially hosting 500 billion trees capable of capturing more than 200 billion tonnes of carbon dioxide at maturity. It would be a serious help to the environment.
Bioenergy now holds a 50 percent share of the world’s renewables consumption—as much as hydro, wind, solar and all others combined. It’s good news, but not entirely. If we consider that increasing desertification and rising ocean levels will take away more arable (可耕种的) land, we arrive at a crucial “trilemma”(三难困境). Should we use our spare soil for agriculture, reforestation or bioenergy?
Such a question would make sense in a multilateral, harmonious world, not on a planet where the richest country cancels an environment-saving agreement, thus encouraging the most tropically-forested nation to set about cutting trees.
Last year, 36,000 square kilometers of forest was cut down. Wouldn’t it be better to start by stopping deforestation altogether? Animal farming takes up 77 percent of the world’s arable land and provides us with 18 percent of the calories. Shouldn’t we cut back on global meat consumption? Modern bioenergy is already available. Shouldn’t we get rid of first-generation biofuels, which are produced from food crops?
1. What’s the IPCC’s attitude to the widespread planting?A.Ambiguous | B.Positive | C.Disapproving | D.Uncaring |
A.Add some background information. | B.Summarize the previous paragraphs. |
C.Provide some advice for the readers. | D.Introduce a new topic for discussion. |

10 . A young Dutch inventor is widening his effort to cleanup floating (浮动的) plastic from the Pacific Ocean. He has developed a floating device (设备) to trap plastic waste moving into rivers before it reaches the oceans.
Boyan Slat was just 18 years old when he invented a system for catching waste in the ocean. He also founded an environmental group called “The Ocean Cleanup”. Its purpose is to develop the system. Last year, Slat showed the next step: a floating device which is called Interceptor. It removes plastic out of rivers. The device is powered by energy from the sun. “The 1,000 rivers are responsible for about 80% of plastic going into the world’s oceans,” said Slat. Three of the machines have already been used. Each machine costs about $775, 660, but the cost might drop as production increases.
Since they were used, the machines have been doing very well, collecting the plastic bottles and all the rubbish in the rivers. According to Slat, it is necessary to close “the tap”, which means preventing more plastic from reaching the ocean in the first place. He wanted to clean them all in the next five years. “This is not going to be easy, but if we do get this done, we could truly make our oceans again, ”said Slat.
The device is designed to be safe in rivers. Its nose is shaped to change directions to keep it away from larger floating things. It works by guiding plastic waste into an opening in the front of the device. The waste is then carried inside the machine where it is dropped into containers. The devices ends a text message to local operators that can come and empty it when it is full.
