标题: 还有一道题~~~~GWD3-Q40!!!! [打印本页] 作者: carvinhuang 时间: 2011-3-22 20:13 标题: 还有一道题~~~~GWD3-Q40!!!! Two centuries ago, Tufe Peninsula became separated form the mainland, isolating on the newly formed Tufe Island a population of Turfil sunflowers. This population’s descendants grow to be, on average, 40 centimeters shorter than Turfil sunflowers found on the mainland. Tufe Island is significantly drier than Tufe Peninsula was. So the current average height of Tufe’s Turfil sunflowers is undoubtedly at least partially attributable to changes in Tufe’s environmental conditions.
Which of the following is an assumption on which the argument depends?
文中我有一句话理解不了:Tufe Peninsula became separated form the mainland, isolating on the newly formed Tufe Island a population of Turfil sunflowers. 请问Tufe Peninsula 和 Tufe Island 不是同一个地方吗???为什么后面会说:Tufe Island is significantly drier than Tufe Peninsula was.作者: cycyang 时间: 2011-3-22 20:43

那它文中后来那句:Tufe Island is significantly drier than Tufe Peninsula was。 就是说独立后的Tufe Island 比 原来还是Tufe Peninsula 更要干旱咯?而 Tufe Peninsula 原本是跟大陆连在一起的,所以在这里就代表了大陆的意思?作者: boozy 时间: 2011-3-23 15:47
是的。作者: carvinhuang 时间: 2011-3-23 19:36

请教为何第四个选项错误?D. The soil on Tufe Island, unlike that on the mainland, lacks important nutrients that help Turfil sunflowers survive and grow tall in a dry environment.作者: dawn19 时间: 2011-12-7 11:16
解释一下为什么D错:D说是岛上的土的原因没有帮助花在干旱环境下长高。还是跟环境有关。 注意结论说at least partially,这并不是一个绝对化的结论。作者的结论只是说至少部分是环境因素导致的,没有绝对化,没有否定其他原因。就算有跟岛上气候相关的其他原因也不能削弱作者的结论。所以正确答案是这样来削弱的:根本一点不管岛上的什么事,是大陆的变化问题。 欢迎指正~作者: love凤巢 时间: 2013-4-11 15:03
为什么我觉得那个 form 的单词放在那边那么的奇怪呢?感觉那句话读不通啊。是不是应该改成from 呢?作者: ScarlettDeng 时间: 2018-8-9 15:04
和大陆连在一起的时候,并不是四面环海,所以叫做peninsula半岛,和大陆分开之后就是四面环海啦,就可以单独成岛了。
