[求助]OG11-37 紫皮书

37．Certain messenger molecules fight damage to the lungs from noxious air by telling the muscle cells encircling the lungs’ airways to contract．This partially seals off the lungs．An asthma attack occurs when the messenger molecules are activated unnecessarily, in response to harmless things like pollen or household dust．

 

Which of the following，if true，points to the most serious flaw of a plan to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules referred to above?

 

(A)  Researchers do not yet know how the body produces the messenger molecules that trigger asthma attacks．

(B)  Researchers do not yet know what makes one person's messenger molecules more easily activated than another's．

(C)  Such a medication would not become available for several years，because of long lead times in both development and manufacture．

(D)  Such a medication would be unable to distinguish between messages triggered by pollen and household dust and messages triggered by noxious air．

(E)  Such a medication would be a preventative only and would be unable to alleviate an asthma attack once it had started．

 

看了N遍也无法理解原文的意思，糟糕的阅读啊有哪位高手帮我翻译一下？谢谢！

一個已知的訊息傳遞分子 會藉由通知圍繞在肺部的那些會經由空氣被傳染的肌肉細胞,來對抗那些從有毒的空氣對肺所造成的損害.

這個機制可以部份的將肺部防護起來

而氣喘的發生 是由於這些訊息細胞因著一些並非真正有毒的物質 如:花粉 或 灰塵, 而做出不必要的反應並啟動上述的傳遞機制, 

Hope helps
