Return of the New World Screwworm to the United States
新世界螺旋蠅重返美國
Introduction
The United States Department of Agriculture has confirmed that the New World screwworm has been found in Texas, leading to a coordinated effort across several states to contain the pest.
美國農業部已確認在德克薩斯州發現新世界螺旋蠅，導致多個州展開協調行動以控制該害蟲。
Main Body
The New World screwworm is a dangerous parasite that attacks warm-blooded animals. Its larvae enter open wounds and destroy healthy tissue, which poses a serious threat to livestock. This situation is particularly concerning because the parasite had been completely removed from the U.S. in 1966. Consequently, officials have introduced strict biosecurity rules to prevent major losses in animal production.
新世界螺旋蠅是一種危險的寄生蟲，會攻擊溫血動物。其幼蟲會進入開放性傷口並破壞健康組織，對牲畜構成嚴重威脅。這種情況尤其令人擔憂，因為該寄生蟲在1966年已從美國完全清除。因此，官員已引入嚴格的生物安全規定，以防止畜產遭受重大損失。
Government responses have been diverse. Secretary of Agriculture Brooke Rollins announced the use of the 'sterile insect technique' (SIT) to reduce the fly population. Meanwhile, state governments have taken their own steps; for example, the Governor of Texas declared a disaster, and Florida created emergency rules to stop the import of animals from high-risk areas. Furthermore, authorities in Louisiana, New Mexico, and Arkansas have received guidance to stop the parasite from spreading further.
政府的應對措施各異。農業部長 Brooke Rollins 宣布使用「不育昆蟲技術」(SIT) 來減少蠅群數量。與此同時，各州政府採取了各自的措施；例如，德克薩斯州州長宣布進入災害狀態，而佛羅里達州則制定了緊急規則，停止從高風險地區進口動物。此外，路易斯安那州、新墨西哥州和阿肯色州的當局已收到指引，以防止寄生蟲進一步擴散。
Conclusion
Federal and state agencies are now using sterile flies and travel restrictions to keep the parasite contained within Texas.
聯邦與州政府機構目前正利用不育蠅及旅行限制，將該寄生蟲控制在德克薩斯州境內。

🚀 The "Logic Link" Secret
To move from A2 to B2, you must stop using only and, but, and because. B2 speakers use Connectors to show how one idea leads to another.
Look at this specific sequence from the text:
*"...the parasite had been completely removed from the U.S. in 1966. Consequently, officials have introduced strict biosecurity rules..."
The Magic Word: Consequently At A2, you would say: "The parasite was gone, so they made rules." At B2, you say: "The parasite was gone; consequently, they introduced rules."
Why this matters:
Consequently is a formal way to say "as a result." It transforms a simple sentence into a professional observation. It tells the reader: 'I am not just giving you facts; I am explaining the cause-and-effect relationship.'
🛠️ Level-Up Your Transitions
B2 fluency is about variety. The article uses three different "Bridge Words" to add information without sounding repetitive:
-
Furthermore (Use this instead of 'also' or 'and') Example: "Authorities received guidance... Furthermore, they are using sterile flies."
-
Meanwhile (Use this when two things happen at the same time in different places) Example: "The Secretary announced a plan. Meanwhile, Texas declared a disaster."
-
Particularly (Use this to highlight the most important part of a problem) Example: "This situation is particularly concerning..."
💡 Quick Tip for the Jump: Next time you write a paragraph, challenge yourself to replace one 'and' with 'furthermore' and one 'so' with 'consequently'. You will instantly sound more academic and precise.
