OG161

[ying]

161. A wildlife expert predicts that the reintroduction of the caribou into northern Minnesota would fail if the density of the timber wolf population in that region is more numerous than one wolf for every 39square miles.
(B) would fail provided the density of the timber wolf population in that region is more than
(C) should fail if the timber wolf density is that region was greater than
(D) will fail if the density of the timber wolf population is that region is greater than
(E) will fail if the timber wolf density in that region were more numerous than
D, the best choice. Choice A misconstrues density with more numerous than, and B uses the pretentious and illogical word provided for if in a conditional clause after a negative idea(would fail) 請問og這句話解釋是什麼意思

[poli]

我覺得它要說明的是
第一個要形容比較density要用greater。
第二個要使用條件情況的子句時，前面否定語氣時，
不可使用provided。

那如果不是否定的情況下應該是可用吧?

[soaringally]

對阿 我對這題歐機的解釋也不釋很清楚 希望各為牛牛能提供一些解釋
到底什麼情況才可以用provided當作條件句? 跟if有什麼差異?
牛牛們! 咖緊出來吧~

===============================================
LDOCE
PROVIDED
used to say that something will only be possible if something else happens or is done
synonym providing
He can come with us, provided he pays for his own meals.
There's no annual fee provided that you use the credit card at least six times a year.

Cambridge Learner's Dictionary
provided (that)
only if
He's welcome to come along, provided that he behaves himself.

剑桥国际英语词典（CIDE）的解释是：
if, or only if
Provided (that) there are no objections, we will begin with item three on the agenda.
He says he'll go parachuting provided/providing (that) you do too.

SOED
provided
On the condition, supposition, or understanding that, or that; it being stipulated or arranged that or that.
Allowed to talk..provided that they did not raise their voices.
M. Keane Jane did not mind expense provided she got what she wanted.
（注：He was released on bail on condition that he did not go within half a mile of his mother’s address. On the condition表达的明显是必要条件。）

总结：虽然有些词典也认为其有IF的含义，但大多数还是认可且只认可作only if解。而only if的意思是“只有”，表达的是必要条件（上面所有的例子我们当作必要条件来理解都不会出现荒谬的意思）。相反IF表达的是充分条件。

我想請問一下：predicts that....
這題為什麼 predicts 後面是條件句 will fail...，而不是用假設句 would fail... ？

OG 裡這一段看不太懂。請牛牛幫忙解答一下。這一段是指 predicts, will fail, is 三個連起來是固定用法嗎？
D, the best choice, uses a correct sequence of present and future indicative verb forms -- predicts, will fail, and is -- in the three related clauses.

[fender]

再頂，還是不懂，請牛牛們出來解答吧^^

[hsudk]

哪裡不懂？

[fender]

我想請教
在此可不可以用would fail???

或者是一定要用will fail
是因為predict的關係所以要用未來式嗎

謝謝解答

[hsudk]

選項(A)錯的關鍵不是在前面的predict，而是在後面的if; if 的主句和從句有很嚴格的時態要求：
1.若 if 後面跟的是現在式，則從句必須用現在式或未來式(will) => A錯
2.若 if 後面跟的是過去式，則從句必須用would，表示假設語氣

謝謝大大解答
我可不可以在問一個笨問題
下列二句語意上有何差別
1.If it is rain, I will not go.
2.If it was rain, I would not go.


我知道這個問題很笨
還是請大大幫我解答
第一句的句型是否稱為條件句
第二句的句型是否稱為假設句
二句有什麼樣的差別
我總是沒搞懂過~"~

再次感謝^^

[kenlo2006]

我覺得差別大呦

1. 語意表下雨這件事機率上是極可能的
2. ...............................與事實相反的

大家請指正

請問E選項OG的解釋
(E) will fail if the timber wolf density in that region were more numerous than

OG說timber wolf density does not clear refer to the population.

我不太懂他這裡的意思, 是改變原本的句意嗎??

[dibert8]

GMAT 的考題裡,會用 N of ... 來明確指出主角是 N, 與 adj.+N 的結構比較起來,後者相對不明確,尤其是 adj. 用名詞的時候.
timber wolf density 主角是 timer? wolf? density? 是什麼 density?

[rainwang]

謝謝dibert8的回答!!!^^

[lichard]

正確答案
A wildlife expert predicts that the reintroduction of the caribou into northern Minnesota will fail if the density of the timber wolf population is that region is greater than one wolf for every 39square miles.
我想請問的 是哪兩個 東西在比較啊?? 頭有點昏了
