※ 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...
