寄托兑换店纪念章 寄托16周年纪念勋章 2016 US-applicant

发表于 2017-8-7 10:04:16 |显示全部楼层
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.

答案给的是E,但我觉得应该选A,理由是最后一句的 no evidence 就是削弱

the answer: seasonal breeding 原因是他们幼虫转移过程中需要藻类(而藻类随季节变化)
researchers 没有发现这样的两类species:提供蛋黄的(幼虫不用藻类可以成活,不用选季节繁殖),没有季节性藻类爆发(任何时候都有藻类,不用选季节繁殖)
所以支持上文的answer

不知道楼主想明白没有,我也不理解这道题,为什么没有找到季节性的海藻就支持了seasonal breeding的猜想…………
