TPO13 passage2第5题

Paragraph 2: When crayfish are kept continuously in the dark, even for four to five months, their compound eyes continue to adjust on a daily schedule for daytime and nighttime vision. Horseshoe crabs kept in the dark continuously for a year were found to maintain a persistent rhythm of brain activity that similarly adapts their eyes on a daily schedule for bright or for weak light. Like almost all daily cycles of animals deprived of environmental cues, those measured for the horseshoe crabs in these conditions were not exactly 24 hours. Such a rhythm whose period is approximately—but not exactly—a day is called circadian. For different individual horseshoe crabs, the circadian period ranged from 22.2 to 25.5 hours. A particular animal typically maintains its own characteristic cycle duration with great precision for many days. Indeed, stability of the biological clock's period is one of its major features, even when the organism's environment is subjected to considerable changes in factors, such as temperature, that would be expected to affect biological activity strongly. Further evidence for persistent internal rhythms appears when the usual external cycles are shifted—either experimentally or by rapid east-west travel over great distances. Typically, the animal's daily internally generated cycle of activity continues without change. As a result, its activities are shifted relative to the external cycle of the new environment. The disorienting effects of this mismatch between external time cues and internal schedules may persist, like our jet lag, for several days or weeks until certain cues such as the daylight/darkness cycle reset the organism's clock to synchronize with the daily rhythm of the new environment.

5. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
○Stability, a feature of the biological clock's period, depends on changeable factors such as temperature.
○A major feature of the biological clock is that its period does not change despite significant changes in the environment.
○A factor such as temperature is an important feature in the establishment of the biological clock's period.
○Biological activity is not strongly affected by changes in temperature.

原文中加黑的那句话，我怎么后半句话的that would be expected to affect biological activity strongly我理解的是会有很大的影响呢？参考译文里面翻译的是确实，稳定性是生物钟最重要的特性之一，即使是在生物所处的环境的诸多要素中发生了相当大的改变，例如温度，不能对生物钟产生很大影响。
由于原句意思领会错了，导致选错了。求各位大神指点。。。。

选第二个吧。
这个句子的核心是前半句，stability是一个主要特征，even引导的是一个让步，你看到的这个翻译：“即使是在生物所处的环境的诸多要素中发生了相当大的改变，例如温度，不能对生物钟产生很大影响。”
即使诸多要素发生改变，仍然stability，实际上是对前半句的一个类似strengthen的肯定，强调的还是stability。所以这个句子的核心就是前半句的意思。
第一个选项你看它的意思depends on chageable factors把重心放错了。
第二个表示的就是stability的意思->does not change despite....相当于同义改写
第三个选项扯到一边去了。
第四个也扯远了。。。

原句中“that would be expected to affect biological activity strongly"我无法理解affect strongly，说影响很大，又说是没有影响，会一直stability，求大神解答啊

你说的这个句子时修饰temperature的，不是削弱主句的。
“even blahblah...（举例）temperature被认为会对Biological activity影响很大，但即使它有这个作用，仍然stability”。
看出来了吗？

就是说affect strongly的是biological activity,尽管对biological activity 有很大的影响，但不会影响其stability,是这样吧？？我理解的对不？？

对的。
整个的意思就是说，尽管有对其影响很大的因素，但它仍然保持了稳定。
