想請問一下各位高手~~~ 14.Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points. The activity of animals is usually coordinated with periodically recurring events in the environment. ○ Most animals survive and reproduce successfully without coordinating their activities to external environmental rhythms. ○ The circadian period of an animal's internal clock is genetically determined and basically unchangeable. ○ Environmental cues such as a change in temperature are enough to reset an animal's clock. ○ Animals have internal clocks that influence their activities even when environmental cues are absent. ○ Animals are less affected by large differences between their internal rhythms and the local solar day than are humans ○ Because an animal's internal clock does not operate on a 24-hour cycle, environmental stimuli are needed to keep the biological day aligned with the solar day. ----------------------------------------------------------------------------- 我選 2 4 6，但正確答案是1 2 6。可是第一段的第一句話不是說 Survival and successful reproduction usually require the activities of animals to be coordinated with predictable events around them. 還有，第一段的最後一句話 The continuation of biological rhythms in an organism without external cues attests to its having an internal clock. 不正是support第四項嗎? 請各位高手幫忙解惑，謝謝! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.119.175.109
