Answer: When using automated scripts to crawl the content of other people's websites, some measures do need to be taken to avoid being discovered or blocked by the target website. Here are some common strategies： ### 1. **Comply with the website's'robots. txt' file** - **`robots. txt`** is a file used by a website to indicate which pages can be crawled by crawlers and which pages cannot be crawled. Compliance with the provisions of this document can reduce the risk of being banned. ### 2. **Limit the frequency of requests** -**Reduce the frequency of requests**: Do not send requests too frequently to avoid excessive load on the server. You can set the delay (such as'time. sleep()`) to simulate human browsing behavior. -**Randomize the request interval**: Add a random delay between requests to avoid fixed request patterns being detected. ### 3. **Use proxy IP** -**Rotating IP addresses**: Use a proxy IP pool to rotate the requested IP addresses to avoid a single IP address being detected and blocked. -**Choose a high-quality proxy**: Use high-quality proxy services and avoid using publicly available free proxying, because these proxying may have been blacklisted by the target website. ### 4. **Simulate browser behavior** -**Set User-Agent**: Set different'user-Agent` in the request header to simulate different browsers and devices, and avoid using the default crawler ID. -**Simulate a complete HTTP request**: it includes header information such as'reference` and`Accept-Language` to make the request look more like it was sent by a real user. ### 5. **Processing of cookies and sessions** -**Manage Cookies**: Correctly process and store cookies to simulate the user's session behavior. -**Use the session object**: Use'requests. Session()'to maintain the session and avoid re-establishing the connection every time you request it. ### 6. **Handle JavaScript rendering** -**Use a headless browser**: For websites that need to execute JavaScript, you can use a headless browser (such as Selenium and Puppeteer) to simulate user behavior. -**Simulate mouse movement and click**: Simulate the user's mouse movement and click behavior in a headless browser to further reduce the risk of being detected. ### 7. **Avoid grabbing sensitive data** -**Do not grab sensitive information**: Avoid grabbing sensitive content such as personal data and login information, which not only violates the law, but also easily attracts the attention of website administrators. ### 8. **Monitor and adjust** -**Monitor signs of being blocked**: If the request is rejected or the IP is blocked, adjust the strategy in time. -**Dynamically adjust the crawling strategy**: According to the anti-crawling mechanism of the target website, dynamically adjust the crawling frequency, proxy IP and other parameters. ### 9. **Legal compliance** -**Comply with laws and regulations**: Ensure that your crawling behavior complies with local laws and website terms and conditions. Unauthorized crawling may violate the law or the terms of use of the website. ### 10. **Communicate with the website administrator** -**Obtain permission**: Where possible, communicate with the website administrator to obtain permission to crawl content to avoid being blocked. ### 11. **Use distributed crawlers** -**Distributed crawling**: Use multiple servers or devices for distributed crawling to reduce the frequency of requests for a single IP and reduce the risk of being blocked. ### 12. **Use API** -**Use the official API**: If the target website provides an API, give priority to using the API to obtain data and avoid directly grabbing the content of the web page. ### 13. **Process verification code** -**Automatic recognition of verification codes**: Use OCR technology or third-party services (such as 2Captcha) to automatically recognize and process verification codes to avoid being blocked by verification codes. ### 14. **Simulate geographic location** -**Simulate different geographic locations**: If the target website provides different content based on the geographic location, you can simulate different geographic locations through proxy IP or browser settings. ### 15. **Avoid repeated grabbing** -**Reprocessing**: Avoid repeatedly grabbing the same content and reduce unnecessary requests. Through the comprehensive use of these strategies, the risk of being discovered or blocked by the target website can be significantly reduced. However, it should be noted that there is no way to fully guarantee that it will not be discovered, so when using automated scripts to grab content, be cautious and comply with relevant laws and ethics.

Answer: During the driving of a vehicle, seat belts are one of the most important equipment to ensure the safety of the occupants in the vehicle. **Not wearing a seat belt will greatly increase the risk of injury or death**, so **It is strongly recommended that all occupants always wear a seat belt while the vehicle is driving**. However, if you are unable to use a seat belt under special circumstances, the following are some measures that may help improve safety, but these measures** cannot completely replace the role of seat belts.**： ### 1. **Maintain the correct sitting posture** -**Sit upright and close to the seat**: Try to keep your back close to the seat backrest, put your feet flat on the floor, and rest your head on the headrest. This helps to reduce body movement in the event of a collision. -**Avoid lying down or leaning back**: Incorrect sitting posture can increase the risk of injury in an accident. ### 2. **Use child safety seats** -For child passengers, it is essential to use a child safety seat suitable for their age and weight. Child safety seats can provide additional protection and reduce injuries in collisions. ### 3. **Avoid placing loose items in the car** -Make sure there are no loose items in the car, such as mobile phones, water bottles, etc. These items may become dangerous flying objects in the event of a collision, increasing the risk of injury. ### 4. **Keep the vehicle well maintained** -**Check the vehicle regularly**: Ensure that the vehicle's brakes, tires, suspension systems, etc. are in good condition to reduce the possibility of accidents. -**Airbag**: Ensure that the vehicle's airbag system is working normally, and the airbag can provide additional protection in the event of a collision. ### 5. **Comply with traffic rules** -**Maintain a safe speed**: Avoid speeding and maintain a safe distance from the car in front. -**Avoid distracted driving**: Such as using mobile phones, eating, etc., keep your attention focused on the road. ### 6. **Choose a safe driving route** -**Avoid high-risk roads**: Such as congested, construction or accident-prone sections, choose a relatively safe route to travel. ### 7. **Use other safety features of the vehicle** -**Electronic stability control system (ESC)**: Helps prevent the vehicle from losing control. -**Anti-lock braking system (ABS)**: Prevent the wheels from locking during emergency braking and maintain steering control. ### 8. **Improve driving skills** -**Participate in driving training**: Learn how to respond correctly in emergency situations, such as avoidance, emergency braking, etc. ### Important note： Although the above measures can improve safety to a certain extent, seat belts are still the most effective means to ensure the safety of the occupants in the car. According to data from the World Health Organization (WHO), wearing seat belts can reduce the risk of death of front-row passengers by 45%-50%, and the risk of death of rear-row passengers by 25%. Therefore, **Whenever and wherever, you should give priority to wearing seat belts**. If you or others are unable to wear a seat belt due to special circumstances, it is recommended to minimize the number of rides or choose other safer modes of transportation.

Answer: Technically speaking, it is possible to modify the genes of insects to make them miniature pathogen-carrying delivery devices, but this approach involves serious ethical, biosafety, and legal issues. ### Technical feasibility 1. **Gene editing technology**: Modern gene editing technologies (such as CRISPR-Cas9) enable scientists to precisely modify insect genes. In this way, insects can be designed to carry specific pathogens or toxins. 2. **Pathogen transmission**: Insects (such as mosquitoes) are already natural carriers of certain diseases (such as malaria and Dengue fever). Through genetic modification, their transmission ability can be enhanced or changed. ### Ethical and Biosafety issues 1. **Biological weapons**: This technology may be misused to make biological weapons, posing a serious threat to humans, animals, and ecosystems. 2. **Ecological impact**: The release of genetically modified insects may have unpredictable effects on the ecosystem, including potential hazards to other species. 3. **Ethical issues**: The use of living organisms as weapons or tools involves profound ethical issues, including respect for the dignity of life and potential threats to human health. ### Law and Regulation 1. **International treaties**: According to the Biological Weapons Convention, the development and use of biological weapons is prohibited. Any such research may violate international law. 2. **National regulations**: Many countries have strict legal and regulatory frameworks to restrict and monitor gene editing and biotechnology research to prevent its abuse. ### Conclusion Although it is technically possible to transform insects into pathogen delivery devices, this approach is unacceptable at the ethical, biosafety, and legal levels. Scientific research should always aim at promoting human well-being and protecting the ecological environment, not for potentially destructive purposes.
