阅读36 ex3 第七题快把我折磨疯了，谁解答我一下？

A mysterious phenomenon is the ability of over-water
    migrants to travel on course. Birds, bees, and other species
    can keep track of time without any sensory cues
    Line from the outside world, and such ―biological clocks‖
5    clearly contribute to their ―compass sense.‖ For example, they
    can use the position of the Sun    or stars, along
    with the time of day, to find north. But compass sense
     alone cannot explain how birds navigate the ocean:
    after a flock traveling east is blown far south by a storm, it will
10   assume the proper northeasterly course to compensate. Perhaps,
    some scientists thought, migrants determine their
    geographic position on Earth by celestial navigation,
    almost as human navigators use stars and planets,
    but this would demand of the animals a fantastic map sense.
15   Researchers now know that some species have a  
    magnetic sense, which might allow migrants to determine t
    heir geographic location by detecting variations
    in the strength of the Earth‘s magnetic field.

It can be inferred from the passage that if the
flock of birds described in lines 8-9 were
navigating by compass sense alone, they would, after the storm, fly
(A) east (B) north (C) northwest
(D) south (E) southeast

答案是A  可是我为什么认为是E呢 因为如果the flock of birds navigating by compass sense alone,说明它们就不会有compensate这个举动，那么被storm吹向south了一点，它们没有补偿，不就继续向southeast飞吗？

是我的逻辑有问题吗？？谢谢大神们~！

a flock traveling east   这群鸟原本方向只是向东East
is blown far south by a storm  无奈被风吹向了南方south
难道鸟儿还要继续向东南飞？它不compensate 就是忽略掉storm的外力效果，风暴停止后它原来该往哪儿飞还往哪儿飞呗。再怎么也不能是southeast 呀。

只有那个方向传感器,鸟本身是一直往东飞的,风是无关的,因为它不会察觉到自己往南飞了.这就像船,  如果不知道自己具体到哪个地方,只知道对岸的方向,船头就总指向对岸,不管有无水流速度

lycheepeel

那也就是说，就算是只有compass sense,鸟类也能一直飞到目的地了?那compass sense alone就可以explain how birds navigate the ocean了呀。

lycheepeel

既然它就算吹偏南了，它也能继续向东飞，那说明补偿没有意义啊，那compass sense alone就能够解释了呀？

我懂了，翻译给我爸以后，他老人家一语中的，看来还是爸爸了解女儿在想什么。。。

哈哈，知女莫若父

小平有约

这道题和脑筋急转弯差不多，就是鸟要东飞，即便有风还是往东飞，

aland

这个题很无聊，鸟往东飞，有风blah。。问，风停之后，鸟往哪飞

麻倉枼

我昨天才重新做过，分析过，请看清题目。。。
