修辞目的题(rhetorical purpose questions)是新托福阅读中难度较大的题型之一。这种题型对于国内考生来说较为陌生，在考场上时间紧张的情况下考生往往不知该在文中什么地方找答案。本文将通过实际解题方法的透彻分析，为大家揭秘托福阅读中的修辞目的题应该遵循什么样的步骤。
Paragraph 1：Survivaland successful reproduction usually require the activities of animals to becoordinated with predictable events around them. Consequently,the timing and rhythms of biological functions must closelymatch periodic events like the solar day, the tides, the lunar cycle, and theseasons. The relations between animal activity andthese periods, particularly for the daily rhythms, have been of such interest andimportance that a huge amount of work has been done on them and the specialresearch field of chronobiology has emerged. Normally, the constantly changinglevels of an animal's activity—sleeping, feeding,moving, reproducing, metabolizing, and producing enzymes and hormones, forexample—are well coordinated withenvironmental rhythms, but the key question is whether the animal's schedule isdriven by external cues, such as sunrise or sunset, or is instead dependentsomehow on internal timers that themselves generate the observedbiological rhythms. Almost universally, biologists accept the idea that all eukaryotes (a category that includes mostorganisms except bacteria and certain algae) have internal clocks. Byisolating organisms completely from external periodic cues, biologists learnedthat organisms have internal clocks. Forinstance, apparently normal daily periods of biological activity were maintained for about a week by the fungusNeurospora when it was intentionally isolated from all geophysicaltiming cues while orbiting in a space shuttle. The continuation of biologicalrhythms in an organism without external cues attests to its having an internalclock.
2. In paragraph 1, the experiment on the Neurospora is mentioned to illustrate
A the existence of weekly periods of activity as well as daily ones
B thefinding of evidence that organisms have internal clocks
C the effect of space on theinternal clocks of organisms
D the isolation of one partof an organism's cycle for study
解题步骤：
1 在题目中找关键词，词组，句子。
本题关键词为Neurospora
2 用关键词在段落中定位，找到定位句。
本题定位句为For instance,apparently normal daily periods of biological activity were maintained for about a week by the fungus Neurospora when it wasintentionally isolated from all geophysical timing cues while orbiting in aspace shuttle.
一般啊，如果定位句里有for instance，for example等时，必定要看前一句的，那么把这两句综合起来就是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 fungusNeurospora when it was intentionally isolated from all geophysical timing cues while orbiting in a space shuttle.
句意：通过彻底地把有机体与外部周期信号隔离开来，生物学家发现有机体尤其内在的生物钟。例如，Neurospora真菌在梭形空间中做轨道运动时，人为地将其从所有地球物理时间信号中隔离开来，很明显其每天正常的生理活动周期维持约有一周。显然呀，举得例子是为了说明organisms有自己内在的生物钟。
3看选项，选出符合句意的选项。
A the existence of weeklyperiods of activity as well as daily ones
每周和每天生理活动周期的存在
B thefinding of evidence that organisms have internal clocks
有机体有内在生物钟的发现
C the effect of space on theinternal clocks of organisms
空间对有机体内在生物钟的影响
D the isolation of one partof an organism's cycle for study
隔离有机体生理周期的一部分用来研究
显然B选项最符合题意。
