标题: OG-122will 和would求教
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 39 square
miles.
?? (A) would fail if the density of the timber wolf
population in that region is more numerous
?? (B) would fail provided the density of the timber wolf
population in that region is more
???? (C) should fail if the timber wolf density in that region
was greater
???? (D) will fail if the density of the timber wolf population
in that region is greater
?? (E) will fail if the timber wolf density in that region
were more numerous

为什么用will呢，OG解答说是对于将来的一种预测，可是预测不是用虚拟语气吗？求好心人解答

zhao的解答每次都那么高深莫测。。。。
首先给一个统计学规律吧~关于predict，我之前搜过所有prep和og的句子，除了一道题里在prediction之后所有选项都用了could之外，其它所有有predict的正确句子中，都是主句是现在时就用will,主句是过去式时才用would
再给出ron关于predict后时态的看法：'predict' doesn't go with command subjunctive, which goes with orders, requests, wishes, and the like, but not with predictions.
predictions should take the future tense, because they're predictions about ... the future!

ron还说过
if you see a SPLIT between “will” and “would”, then it's most likely that we are dealing with a tense issue.
* if we are actually talking about an event that has not occurred yet -- i.e., an event that is genuinely in the future -- then we should usually use “will”.
* if we are talking about an event that was still a future event at the time described in the sentence (but is no longer a future event), then we should use “would”.
a couple of examples:
several experts have predicted that brazil will win the world cup in 2014. (as of this writing it is not 2014 yet, so the future tense is appropriate)
last year, several experts predicted that brazil would win this year's world cup. (this year's world cup is now over, so it's inappropriate to use the future tense. therefore, we use “would”, which is a tense that we use to describe something that was once a future event, but is no longer)
in ancient times, the mayans predicted that the world will end in the year that corresponds to A.D. 2012 on the modern gregorian calendar. (2012 has not happened yet, so we still use the future tense for the prediction -- even though the prediction was made a really, really long time ago)
