1 . Within the beautiful scenery of Wisconsin’s Lake Chippewa lies a natural wonder that is a unique challenge for the local community. This hidden wonder is exactly a giant floating island. The island, made up of plants and trees, sometimes floats around the lake, causing a major inconvenience by blocking (阻塞) an important bridge. Later, the local people came up with a solution to this problem. Every year, local boat owners work together and push the island away from the bridge.
Lake Chippewa was born in 1923 when a vast bog (沼泽) was changed through flooding. Soon after that, many of the dark bogs started rising to the surface and became perfect growing places for plants, with seeds carried by wind and wild birds to this floating place. Over the years, these bogs have grown plants and trees and turned into full islands. As time goes by, plants take root, and the oldest islands even have trees that act as sails (船帆) when the wind blows, moving the entire floating island around the lake.
Although the years-old floating island does not relocate (重新迁移) so often, when it does, it causes trouble for the community by blocking the important bridge that serves as the only passage between the lake’s East and West sides. The only solution is to gather a group of boats, and not just one or two, but dozens of boats working together to push the island away. “It takes a community’s effort, and you must have the winds at your back to push them in,” said a resident. Moving the island also requires precision (精确), as just relocating it a short distance may result in its return within days.
Some people have suggested destroying the floating islands to get rid of the problem. However, the big bog in Lake Chippewa has been around for many years, and during that time a variety of animal and plant species have made it their home. Therefore, local government advises they be dealt with in a way that won’t do harm to wildlife, paying more attention to the fine-drawn balance between human convenience and environmental protection. The annual tradition of relocating Lake Chippewa’s floating island is evidence to the coexistence of man and nature, a heartwarming display of community unity, and a reminder of the importance of preserving the unique areas that enrich our world.

4 . Zhu Dejun’s first job after graduating from college was as a road design engineer in his hometown, Alshaa League, North Chin’s Inner Mongolia autonomous region(内蒙古自治区). In 2011, when Zhu was conducting a road survey along with his colleagues, he saw a plant that he didn’t recognize. Later, Zhu learned that the plant was a saxaul (灌木梭梭) tree which is an excellent tree species for sand fixation and afforestation (造林) in desert areas. Known as a desert guardian, a fully grown saxaul tree can hold together a 10-square-meter patch of desert land, according to Zhu.
Zhu quit (辞去) his job at the design institute in 2014 and joined a nonprofit organization, the Society of Entrepreneurs and Ecology Conservation, or SEE, in the same year, concentrating on dealing with desertification (沙漠化) .During the past eight years, Zhu has been leading a team from SEE to plant saxaul trees in sandy areas in Alshaa League and other places of Inner Mongolia.
In 2014, the SEE launched a project titled “one million saxaul trees”, aiming to reach that number from 2014 to 2023, turning the desert of more than 133, 330 hectares (公顷) back into a satisfying ecosystem. By the end of 2018, half of the organization’s goal had been achieved. In 2016, Ant Finance cooperated with SEE to introduce the Ant Forest platform, not only encouraging people to choose “a low-carbon way” of shopping, traveling and living, but also to help control desertification.
Through the participation of a greater number of online users, who grow virtual trees, the SEE Foundation, set up in 2008, has been providing subsidies (补助金) for local herdsmen and farmers while also offering technological support to plant saxaul trees in desert areas. Now, Zhu is the head of the foundation’s project to fight desertification. He also gives lectures about saxaul trees and the fight against desertification at schools, hoping to raise awareness among young people.

6 . The climate change has become an issue that no one can escape from. If the world wants to limit climate change, water shortage and pollution, we all need to choose “flexitarian” diets, say scientists.
This means eating mainly plant-based food, which is one of three key steps towards a sustainable future for all in 2050, they say. Food waste will need to be halved and farming practices will also have to improve, according to the study. Without action, the impacts of the food system could increase by up to 90%. Fast on the heels of the landmark report of the Intergovernmental Panel on Climate Change(IPCC) comes this new study on how food production and consumption impact major threats to the planet.
The authors say that the food system has a number of significant environmental impacts including being a major driver of climate change, providing freshwater and reducing pollution through over use of nitrogen (氮) and phosphorus (磷).
The study says that thanks to the population and income growth expected between 2010 and2050, these impacts could grow between 50%~90%. This could push our world beyond its geographic boundaries. So when it comes to climate change, the authors looked at what they called a “flexitarian diet”.
“We can eat a range of healthy diets but what they all have in common, according to the latest scientific evidence, is that they are all relatively plant-based,’’ said lead author Dr. Marco Springmann from the University of Oxford.
“You can go from a diet that has small amounts of animal products; some might call it a Mediterranean-based diet; we call it a flexitarian diet. We tried to stay with the most conservative one of these which in our view is the flexitarian one, but even this has only one serving of red meat per week,” he added.
If the world moved to this type of diet, the study found that greenhouse gas emissions (排放) from agriculture would be reduced by more than half.
1. What benefit will the new diets bring to the world?| A．The animals will be saved. | B．People will need more water. |
| C．The climate change will stop. | D．The pollution will be controlled |
| A．Eat animal products every meal. |
| B．Eat plant-based vegetables every meal. |
| C．Eat mainly vegetables and never eat animal products. |
| D．Eat plant-based meal mainly and animal products sometimes. |
| A．The climate will become warmer. | B．The food consumption will increase. |
| C．People will have less greenhouse gas. | D．People will produce more food waste. |
| A．Supportive. | B．Doubtful. | C．Opposed. | D．Indifferent. |

8 . The Great Barrier Reef is the result of millions of years of continental (大陆的) shifts, sea-level changes, and layers of coral (珊瑚) growth. The Reef was built over millennia (数千年) by coral attaching itself to existing dead coral, as it continued to reach toward the light. Like most living things, coral needs the sun to survive and generally lives in shallow waters, where enough sunlight can penetrate (穿透) the water. Sea levels began to rise at the end of the last most recent ice age, about 14,000 years ago. As a result, the previously exposed Reef was covered by water and the coral expanded along the length of the newly revived Reef.
Climate change is having a dangerous impact on this natural wonder. Although coral and algae (海藻) have evolved despite climate change, allowing them to survive, coral has begun producing products that are poisonous to the Reef and block the growth of algae. Additional concerns include the overwhelming amount of pollution and chemical runoff into the water which harms the already affected coral and reduces biodiversity.
The Great Barrier Reef is well known as one of the best diving destinations in the world. You can do your part to help scientists preserve the Reef’s ecosystem while visiting. By paying a visit to the Reef, visitors pay a reef tax that will be used for the management and conservation of the Reef. A lesser-known contribution visitors can make to Reef preservation is signing up for REEFSearch. After signing up, you’ll be sent a field guide that will teach you how to collect information that scientists can use to study the Reef’ s health. During each dive, using the information sent to you, you will look for key species, check for coral conditions, and make note of any garbage found near the Reef. These small contributions can ultimately have a large impact and save one of the great wonders of the world.
