  希望后面有大牛能把这道题定位出来....

  原文还是很难懂的!

  本月狗主:问其他科学家认为意大利那个科学家的研究’’unbelievable’’的assumption 是什么?我选了AP的开口很小只有很tiny 的虫子能进去…(不太确定);还有选项说AP 植物模仿菌类吸引虫子神马的。

  *Q9:下面哪个是正确的?/以下哪些是受到文章support 的?

  选项有:

  1、意大利植物学家(Italian botanist)没有假设(hypothesize)昆虫对授粉起很大作用(insect plays an important role in pollinating)

  2、没有附加的尾巴和没有模仿蘑菇来授粉是一致的(the absence of appendix coincide with the absense of mimicrying funga to pollinate)

  750 狗主确认答案:the absence of appendix relate to the absense of mimicrying funga to pollinate

  *Q10:那个叫Y 什么的特殊结构的假设。

  *Q11:关于鼠尾伪装这个事情,文章strongly suggest 了什么?

  答案选:other lily 不会伪装成mushroom。

  定位这句话:这个mousetail,not like it is in other lily, 伪装成菌菇(mushroom/fungi)的样子。

  *Q12:以下哪项对于AP 的研究成果哪项是正确的?

  但是选项之前蛮类似的,都包括了关于mousetail 啊mimic 什么的。

  备注:

  1 屏半,大把不认识的单词

  背景资料:

  The "tail" has a mushroom odor which is known to attract female fungus gnats as mouse tail pollinators.In the process the gnats lay their eggs in the mouse tail. These eggs hatch 孵化 but the larvae 幼虫 fail to develop, having no actual fungus to eat. Possibly the fly larvae, starving while in pursuit of food inside the spathe, are also needed for full pollination. If the mouse plant happens to gain any degree of nutrient from the eggs & the dead larvae, that would qualify as carnivorous behavior. If not to any degree carniverous, the Mouse Plant is at least parasitic 寄生的, in that it attracts pollinators it in no wise 决不 provides an exchanged benefit.

  来自维基百科

  The plants are monoecious. The spadix has tiny flowers: female flowers, no more than a pistil, at the bottom, then male flowers, actually a group of stamens, and then a blank sterile area. This last part, called'the appendix', consists of sterile flowers, called staminodes, and can be especially large. There is no corolla.

  Once the spathe opens, pollination must happen the same day. The inflorescence, in many species, emits a scent of decaying flesh, in order to attract insects, though a number of species give off a pleasant odor.

  Through a number of ingenious insect traps, pollinating insects are kept inside the spathe to deposit pollen on the female flowers, which stay receptive for only one day, while the male flowers are still closed.

  These open the next day, but by then the female flowers are no longer receptive and so self-pollination is avoided. The male flowers shower the trapped insects with pollen. Once the insects escape, they can then pollinate another flower. Amorphophallus species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) species including Palpifer sexnotatus and Palpifer sordida
