According to the data, animal populations across the world decreased by an average of 69% between 1970 and 2018. Experts say the rapid loss of biodiversity is a serious and worrying sign of what’s to come for the natural world. “The message is clear and the lights are flashing red.” said WWF International Director General Marco Lambertini. Many scientists believe that the main cause of biodiversity loss island-use changes driven by human activities such as the development of basic facilities, energy production and deforestation. But the report suggests that climate change, which has had a wide impact on plant and animal species globally, could become the leading cause of biodiversity loss if rising temperatures aren’t limited to 1.5℃. Lambertini said biodiversity loss and climate change are already responsible for a series of problems for humans, including death and homelessness from extreme weather, a lack of food and water and an increase in the spread of specific diseases. But the terrible news comes with signs of hope: Experts say there are possible solutions to the loss of biodiversity. Solutions range from protecting forests to establishing a cross-border trade system in Africa, the report said. WWF chief scientist Rebecca Shaw said that humans have the opportunity to change how they do things to benefit nature. “Little things that we can do every day can change the direction of these population declines,” said Shaw. 1. What does the new report focus on according to the first paragraph? A. Climate change. B. Forest protection. C. Earth’s biodiversity. D. Wildlife habitat. 2. What maybe the main cause of biodiversity loss currently? A. The spread of specific diseases. B. Climate change on Earth. C. A lack of food and water. D. Human impacts on land. 3. What can be inferred from the last two paragraphs? A. It’s unnecessary for humans to continue benefiting nature. B. There is something humans can do to stop biodiversity loss. C. It’s impossible for humans to stop the decline of biodiversity. D. There is no need for humans to worry about biodiversity loss. 4. In which section of a newspaper may this text appear? A. Environment. B. Economy C. Education. D. Science. 五、（2022-2023学年下学期·福建漳州·高一期末）完形填空 Several years ago, teacher Jennifer Thiessen was writing report cards. Something 1 her.

(世界自然基金会(WWF)和伦敦动物学会的一份新报告发现，通过多年来对全球数千种野生动物种群的数据分析，地球的生物多样性正在减少。)”可知，新报告关注的是地球上的生物多样性。故选C。 2. 细节理解题。根据第四段“Many scientists believe that the main cause of biodiversity loss island-use changes driven by human activities such as the development of basic facilities, energy production and deforestation.(许多科学家认为，生物多样性丧失的主要原因是由人类活动驱动的岛屿利用变化，如基础设施的发展、能源生产和森林砍伐。)”可知，目前，物多样性丧失的主要原因是人类对土地的影响。故选D。 3. 推理判断题。根据倒数第二段末句“Solutions range from protecting forests to establishing a cross-border trade system in Africa, the report said. (报告称，解决方案包括从保护森林到在非洲建立跨境贸易体系。)”以及末段“WWF chief scientist Rebecca Shaw said that humans have the opportunity to change how they do things to benefit nature. “Little things that we can do every day can change the direction of these population declines,” said Shaw. (世界自然基金会首席科学家丽贝卡·肖说，人类有机会改变他们做事的方式，造福大自然。肖说：“我们每天做的一些小事就能改变这些数量下降的方向。”)”可知，人类仍然可以做一些事情阻止生物多样性的下降。故选B。 4. 推理判断题。根据首段“A new report from the World Wildlife Fund (WWF) and the Zoological Society of London found Earth’s biodiversity is decreasing through years of data on thousands of wildlife populations across the world.
