试题详情

题目:

Most of the year, the hermit thrush, a North American songbird, eats a diet consisting mainly of insects, but in autumn, as the thrushes migrate to their Central and South American wintering grounds, they feed almost exclusively on wild berries. Wild berries, however, are not as rich in calories as insects, yet thrushes need to consume plenty of calories in order to complete their migration. One possible explanation is that berries contain other nutrients that thrushes need for migration and that insects lack.

Which of the following, if true, most seriously calls into question the explanation given for the thrush’s diet during migration?

选项:

A、Hermit thrushes, if undernourished, are unable to complete their autumn migration before the onset of winter.
B、Insect species contain certain nutrients that are not found in wild berries.
C、For songbirds, catching insects requires the expenditure of significantly more calories than eating wild berries does.
D、Along the hermit thrushes’ migration routes, insects are abundant throughout the migration season.
E、There are some species of wild berries that hermit thrushes generally do not eat, even though these berry species are exceptionally rich in calories.

答案:

C

提问:

这道题留下B,C和D中错选了D。原文是这个鸟在冬天迁移是只吃果类,即使需要大量的能量。给出的一个解释是果子里含一些营养,而这些营养是虫子不具备的。请问一下 B和D,相对于C来讲,犯了什么逻辑错误。谢谢。

提问:

怎么判断选项是有关无关呢,是要出现原文中的单词吗,像这里的explain中既有berry又有insect,怎么知道哪一个是重点呢,是看主语吗?如果对选项有关无关判断不是很敏感要怎么提高?

提问:

选了E,根据管老师方法,问题明确指向explanation,因此在文章中定位只读最后一句:berry有一种t需要的但是insect没有的营养物质。开始排除选项,A讲时间,排除。B讲营养,有关。C讲卡路里的多少,和营养无关。D。insect数量的多少,无关。E讲卡路里,无关。 根据管老师说法,5个选项如果只有一个相关,不用管方向是否一致,直接选这个选项。因此选了E。

提问:

C和D都是认为“berries包含thrushes没有的营养物质是hermit吃berries的原因”怎么区分?

提问:

老师,这题问哪个选项能质疑文中的解释,我觉得c反驳不了文中的解释啊。文中说浆果含有虫子没有的物质是一种可能的解释,c又给出了另一种解释说是因为抓虫子消耗的卡路里更多,但这只是另一种解释,它成立也并不说明文中的解释不成立啊。请老师解释一下谢谢

提问:

还是跟那个选E的同学是一个思路。我听懂的说能量要考虑获取跟消耗这个逻辑。但我还是听不懂选e的逻辑错误在哪

提问:

要给thrush’s diet during migration找问题,所以就看了最后一句One possible explanation这句。发现是说 berries有一些insects没有的东西,所以这个动物要吃berries。 问驳斥,只有E是说吃不吃berries的,所以选了这E
