Q32:

Macrophages are cells that play a role in the response of the immune system of mice and other mammals to invasive organisms such as bacteria. Unlike other mice, mice that are genetically incapable of making these particular cells do not show elevated levels of nitrates when infected with bacteria.

The statements above, if true, provide the most support for which of the following conclusions?

A.Mice that are unable either to make macrophages or to make them in sufficient numbers will protect themselves from bacterial infections in some other way.
B.Mice that show elevated levels of nitrates can easily fight off most types of bacterial infections.
C.In mice, macrophages play a role in the production of nitrates or inhibit a process by which nitrates are broken down or otherwise eliminated.
D.When a healthy mouse becomes infected with an invasive organism, the number of macrophages in the mouse’s body decreases.
E.Injections of nitrates into mice that lack macrophages will not enhance the ability of these animals’ immune systems to fight off infection

答案C我能夠接受
想知道大家排除E的原因???

除了E有點過分推論外,我認為E若是比較正確的話,應該是will enhance而非will not enhance.從題目來看,似乎nitrate可以抵抗bacteria的入侵

macrophages可以防止一種過程(是一種nitrates被破壞,或消失的過程)
(C)的意思是說:M存在N就存在

很抱歉..這題有一點舊了..不過我還是有一些問題
請教一下大家

從哪裡看出來
nitrate對bacteria ineffection 有幫助
我只看出
正常老鼠
infected with bacteria...則nitrate會升高.....

incapable of making these particular roles--->do not show elevated levels of nitrates(when infected with bacteria)

請問(B)選項是錯在 N can easily fight off most types of B超過題目給的資訊嗎?
還是因為跟M沒有扯上關係?
麻煩指點,謝謝大家!

應該說
用題目所給的那些資訊
是推不出b這個結論
因為題目只說1.m很重要 2.沒有m cell沒有n的上升
推不出有n可以抵抗大部分病毒

這裡可以看得出來嗎?
incapable of making these paticular cells只是說沒有辦法製造Macrophages的老鼠沒有elevated levels of nitrates的跡象~~
並沒有說nitrates 可以抵抗細菌~
我把題目再讀了兩遍還是沒有辦法連結起來耶~~

剛剛看了CD~~覺得這題也許不用想得那麼複雜把它跟bacteria infection連起來~
因為我本來是選(E),錯了~~
下面轉貼自CD~

lawyer:
1。 关键在于理解UNLIKE,Unlike other mice, mice that are genetically incapable of making these particular cells do not show elevated levels of nitrates when infected with bacteria意思为:不能造M的老鼠感染细菌时硝酸盐没有显示升高。能造M的老鼠感染细菌时硝酸盐显示升高(UNLIKE)。C选项说出硝酸盐升高的两种方式,PRODUCTION和 INHIBIT。

2。其它易排除,A较混淆。A的问题在于sufficient。怎样才算sufficient,这概念太含糊,归纳题是不允许这种含糊概念的,再说对那些造M量不足的老鼠,不见得会用其它方式抵抗细菌,难道就不允许由于M细胞不够而生病或根本没事吗。其实我一眼就不喜欢A,它不象归纳题选项,好像跟原文关系不大。感觉上新信息太多,又是some other way,又是sufficient。

若A要能對,問assumption比較像是答案:P
這樣C可以接受,感謝NN們的討論:)

laywer講的對... 他後來又解釋了這個.. 大家看看降有沒更清楚...

1。从单纯找答案角度,对原文的理解仅限于M细胞对老鼠的硝酸盐含量有影响便可以。只有C有这层意思

2。C的意思仅限于“对硝酸盐的产生有作用或抑制硝酸盐的减少”,起作用的结果是“维持升高”(大概念)。也即有两种情况都可以:“维持”,“升高”。原文说的是“升高”的情况(小概念)。原文如果为小概念,那末选项为大概念必然对。比如:原文为leslie123456789GMAT考了800分(小概念),那末选项leslie123456789GMAT考了750分以上(大概念)必然对。

我覺得(e)改成... will enhance the ability of ...也不對

因為文中只說1.m在免役系統抵抗細菌中扮演很重要的角色 2.正常情況下細菌出現-->M上升-->N上升
但是文中都沒說到N能不能抵抗細菌所以(b)(e)都錯
