托福阅读否定事实信息题是阅读考试十大题型之一，通常每篇阅读中都会出现;tpo是托福阅读备考最权威的材料，所以托福小编综合二者，为大家集中整理了tpo阅读中考察的否定事实信息题及其对应的解析，供大家参考使用。本文带来的是TPO13-2的否定事实信息题，一起来看看吧。
TPO13-2 Biological Clocks
Paragraph 1：
Survival and successful reproduction usually require the activities of animals to be coordinated with predictable events around them. Consequently, the timing and rhythms of biological functions must closely match periodic events like the solar day, the tides, the lunar cycle, and the seasons. The relations between animal activity and these periods, particularly for the daily rhythms, have been of such interest and importance that a huge amount of work has been done on them and the special research field of chronobiology has emerged. Normally, the constantly changing levels of an animal's activity—sleeping, feeding, moving, reproducing, metabolizing, and producing enzymes and hormones, for example—are well coordinated with environmental rhythms, but the key question is whether the animal's schedule is driven by external cues, such as sunrise or sunset, or is instead dependent somehow on internal timers that themselves generate the observed biological rhythms. Almost universally, biologists accept the idea that all eukaryotes (a category that includes most organisms except bacteria and certain algae) have internal clocks. By isolating organisms completely from external periodic cues, biologists learned that organisms have internal clocks. For instance, apparently normal daily periods of biological activity were maintained for about a week by the fungus Neurospora when it was intentionally isolated from all geophysical timing cues while orbiting in a space shuttle. The continuation of biological rhythms in an organism without external cues attests to its having an internal clock.
3. According to paragraph 1, all the following are generally assumed to be true EXCEPT:
○ It is important for animals' daily activities to be coordinated with recurring events in their environment.
○ Eukaryotes have internal clocks.
○ The relationship between biological function and environmental cycles is a topic of intense research.
○ Animals' daily rhythms are more dependent on external cues than on internal clocks.
解析：EXCEPT题，排除法。A的activities和coordinate做关键词定位至第一句，正确，不选;B的E做关键词定位至倒数第四句，明确指出有internal，所以正确，不选;C的intense research做关键词定位至第三句，正确，不选;D的比较原文没说，错，选
[1]通常动物的繁衍生息需要动物的活动与周围可预测活动同步。因此，生物功能的时间与节律也就理所应当必须与昼夜交替、潮涨潮落、月圆月缺和四季更迭这样的周期性事件保持大体一致。动物的活动与这些周期之间的关系，特别是与昼夜交替之间的关系，引起人们浓厚的兴趣，而且因为大量的工作都是在其基础之上完成的而意义重大，从而也延伸出了一个特别的研究领域：生物钟学。通常意义上讲，动物活动的经常性转变——例如，睡觉、喂食、活动、繁殖、新陈代谢以及产生酶和荷尔蒙，都与环境的节律同步。但是关键问题在于，动物的作息时间是否受制于外界环境，比如日出日落，又或者是依赖于他们自身独立的生物节律。生物学家普遍认为，所有真核生物(包括除病毒和某些藻类之外的所有生物)都有内部的生物钟。通过将生物与外界的周期性现象完全隔离，生物学家们发现生物的确有生物钟。例如，一种叫脉孢菌 的细菌在航天飞机中与一切地球时间线索隔离的情况下，所有生物日常活动周期可以持续一个礼拜左右。在没有外界信号的时候生物也能延续生物节律，这说明生物是具有生物钟的。
