※ 引述《lovekyoko (匹茲堡的天空)》之銘言： : 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. : 答案是D : 但是我連題目都看不太懂 : 好心的牛人可以翻譯一下嗎 Premise是說有種訊息傳遞的分子要避免有毒氣體傷害肺的方法是碰到有毒氣體的時候,會叫肌肉細胞把肺包起來. 這樣肺會被封起來. 氣喘就是這些訊息傳遞分子碰到無害的花粉或是灰塵也這樣而發生的. 題目是問....如果要避免氣喘就不要接受這些訊息傳遞分子的任何訊息.... (這麼一來,不管是有毒的或是花粉塵埃, 肌肉細胞都不會進行保護) 這麼做最嚴重的flaw會在哪邊? D就是說....這樣的方法無法分辨哪些是花粉灰塵哪些是有毒的... 有毒進去肺部裡面, 老命就歸西了... 翻譯參考一下即可, 向來不大會翻譯QQ" 不知道你問題在哪... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 123.192.191.99 ※ 編輯: giyoshi 來自: 123.192.191.99 (03/27 11:02)
