求教大神这一题
When studying shrimp feeding from hydro-thermal vents at the bottom of the ocean, biologists
were surprised that the shrimps’ reproductive cycles followed seasonal patterns. Far beyond the
reach of sunlight, and with food abundant around the vents all year round, why should such
animals reproduce seasonally? The answer might involve their offspring, which in their larval form drift in the currents to colonize new vents. The larvae must feed during their trip, and their
springtime release coincides with a peak in algae raining down from surface waters. So far,
researchers have found no evidence of seasonal breeding among vent-dwelling species
that provide their offspring with yolk to sustain them or among vent-dwelling species found
in areas of the ocean with not seasonal algae blooms.

1. Which of the following best describes the function of the highlighted sentence?
A. It casts doubt on the accuracy of earlier observations of seasonal breeding among shrimp
species living near hydro-thermal vents.
B. It undermines the explanation proposed for seasonal breeding among some shrimp species
living near hydro-thermal vents.
C. It suggests that alternative theories are needed to explain seasonal breeding among shrimp
species living near hydro-thermal vents.
D. It describes the survival benefits to shrimp of mating in parts of the ocean where algae blooms
rain down abundantly.
E. It supports the explanation proffered for the seasonal breeding observed among some shrimp
species living near hydro-thermal vents.

我不是很懂为什么是答案是E，highlighted sentence不是说no evidence of seasonal breeding吗，那不应该是反对之前给出的seasonal的解释吗？为什么是支持呢？

我的理解是这样的， 原句是no evidence ..... in the areas of the ocean with not seasonal algae blooms, 说明在没有seasonal algae 的地方， shrimp 也不会有seasonal breading, 但是near hydro-thermal vents 的区域是有seasonal algae raining的，因此可以推断出住在hydro thermal vent附近的shrimp是有seasonal breeding 的
简单说就是 no seasonal algae=> no seasonal breeding
seasonal algae=> seasonal breeding

唔。。我大概懂了。但是researchers have found no evidence of seasonal breeding among vent dwelling species that provide their offspring with yolk to sustain them or among vent-dwelling species found in areas of the ocean with not seasonal algae blooms.求大神能翻译下吗？

我看的有点蒙蔽的就是感觉这句话分开就是researchers have found no evidence of seasonal breeding among vent dwelling species that provide their offspring with yolk to sustain them or researchers have found no evidence of seasonal breeding among vent-dwelling species found in areas of the ocean with not seasonal algae blooms.

然后这个researchers have found no evidence of seasonal breeding among vent dwelling species that provide their offspring with yolk to sustain them 怎么感觉跟 The larvae must feed during their trip 这句话冲突了？

没冲突啊，我觉得是前提不一样。。no evidence 的前提是not seasonal algae bloom，而the larvae must feed 的前提是with a peak in algae raining, 这里的peak 就是默认了algae raining 有季节性（否则全年都一样就不会有peak了）

是的，之前没发现这个两个no。。。。
