A new groundbreaking study reveals a landmark breakthrough in the field of snakebite treatment. Researchers, led by David Baker from the University of Washington, have designed new proteins—unlike any found in nature—that can inactivate some of the most poisonous components of snake bite toxins (毒素).

Snakebites represent a substantial global health issue, affecting millions of people each year. According to the World Health Organization, over 2 million people suffer from snakebites annually, with more than 100, 000 deaths and 300, 000 cases of permanent disabilities. Current treatment options, mainly obtained from animal blood, often present drawbacks, including high production costs, limited efficiency, and severe side effects, such as causing shock and breathing difficulties.

Q: Which is a shortcoming of the current snakebite treatments?

They mainly rely on animal blood.

They are effective in certain regions.

They can lead to serious health risks.

They may leave toxins in patients’ bodies.

细节理解题。根据第二段“Current treatment options, mainly obtained from animal blood, often present drawbacks, including high production costs, limited efficiency, and severe side effects, such as causing shock and breathing difficulties. (目前主要从动物血液中获取的治疗方案往往存在缺点，包括生产成本高、效率有限和严重的副作用，例如引起休克和呼吸困难。)”可知，目前蛇咬伤治疗的缺点是会导致严重的健康风险。故选C。
