Step 2 Reading comprehension.
The world’s animal populations have decreased by more than two-thirds since 1970, according to a recent research from the World Wildlife Fund (WWF).
The London group provided information on 32,000 wildlife populations which included more than 5,000 species. The researchers found that population sizes had declined by 69 percent on average. They said the loss of forests, human exploitation（开发）of the environment, pollution, and climate change were great causes of the loss. Land-use change is still the biggest threat to wildlife. However, the researchers added, “if we cannot limit warming to 1.5°C, climate change is likely to become the dominant（首要的） cause of biodiversity loss in the coming years.”
Wildlife populations in Latin America(拉丁美洲) and the Caribbean Sea area（加勒比海地区）were greatly affected. The research showed a 94 percent drop in those areas in over 50 years. Wildlife populations in river and lake habitats decreased the most. Freshwater populations have declined by an average of 83 percent since 1970. For example, one population of pink river dolphins in the Amazon River area of Brazil fell by 65 percent between 1994 and 2016.
These findings are a red flag that warns of a larger system failure on the horizon（很可能即将发生）. Even one species’ population decline can affect other species, eventually impacting the ecosystem’s ability to function. Humans depend on a stable(稳定的) climate, predictable weather patterns（天气模式）, and productive farmland and fisheries（渔业） to thrive（蓬勃发展）, but the current trends are severe（严重的） enough to threaten many life-sustaining（维持生命的） systems.
Our future depends on reversing（扭转）the loss of nature just as much as it depends on addressing（处理） climate change. And you can’t solve one without solving the other. Everyone has a role in reversing these trends, from individuals to companies to governments. If nothing changes, animal populations will undoubtedly continue to fall, driving wildlife to extinction and threatening the integrity（完整） of the ecosystems on which we all depend.

A. Illegal hunting. B. Global warming.
Land-use change. D. Environmental pollution.
2. How does the author explain the decline of freshwater wildlife in paragraph 3
A. By listing figures. B. By analyzing the causes.
C. By making a comparison. D. By referring to a concept（概念）.
3. What can we learn from paragraph 4
A. Climate change threatens many wild animals.
B. Farmland is the basis of life-sustaining systems.
C. Species diversity is important to maintain a stable ecosystem.
D. Extreme weather events have become more frequent.
4. What is the main purpose of the text
A. To explain the difficulty of restoring ecosystems.
B. To call on people to take action to protect nature.
C. To present the increasing trend of climate change.
D. To show people’s efforts in reversing the loss of nature.
