Digital Technology and Wildlife Protection
In recent years, digital technology has become a powerful tool in protecting endangered wildlife species. For example, camera traps equipped with AI algorithms can automatically identify and track rare animals like snow leopards, reducing the need for human rangers to patrol dangerous remote areas.
However, traditional methods of wildlife monitoring often face challenges such as high costs and limited coverage. Poachers also use advanced technology to avoid detection, making it harder to stop illegal hunting.
To address these issues, conservation organizations have started using satellite tracking systems to monitor the migration paths of endangered species. Additionally, they are developing mobile apps that allow local communities to report poaching activities quickly and securely. These apps also provide real-time training on wildlife protection for villagers.
Thanks to these digital solutions, the success rate of stopping illegal poaching has increased by 30% in some regions. Local communities have also become more engaged in protection efforts, as the apps offer them a convenient way to contribute.
36. What is one of the digital tools mentioned for tracking rare animals
A. Satellite navigation systems
B. AI-equipped camera traps
C. Mobile payment platforms
D. Virtual reality devices
37. What is a major challenge of traditional wildlife monitoring methods
A. Low cost and wide coverage
B. Lack of public support
C. High costs and limited coverage
D. Too many digital devices
38. What measure are conservation organizations taking to fight poaching
A. Developing mobile apps for reporting poaching
B. Banning all digital devices used by poachers
C. Reducing the number of human rangers
D. Stopping satellite tracking of migration paths
39. What can we conclude from the passage
A. Digital technology has no effect on wildlife protection
B. Local communities are not involved in protection efforts
C. Digital solutions have helped improve anti-poaching success rates
D. Traditional methods are better than digital tools for wildlife protection

参考范文
Dear Editor,
Digital technology has made our lives more convenient than ever: we can attend online classes, communicate with friends far away, and access abundant information in seconds.
However, excessive use of digital devices can cause problems. Spending too much time on screens harms our eyesight and reduces face-to-face interactions, which may lead to feelings of loneliness.
As middle school students, we should set daily time limits for using digital devices. We can use them to learn new skills and search for study resources instead of mindlessly scrolling through social media. Let’s make digital technology our helpful friend rather than a distraction!
Yours sincerely,
Li Hua
