Q25.
C.The commuter diatom’s biological clock is likely to be more accurate than the biological clock of a species that is subject to less intense environmental pressures.

答案C的意思應該是說，承受較少環境壓力的藻類，他們的生理時鐘會比較不準確，意思就是壓力較多，生理時鐘就較正確。
文章說明藻類的生理時鐘之所以準確，是因為承受環境壓力下所造成的結果，只要不準確的話，就會來不及隱藏到沙中而被海浪沖走。
所以25題應該是選(C)。如果有錯還請各位指正。

我想這題的考點應該就是直接定位 32-38 行∼
謝啦！

GWD 18 一樣的文章 不過有個題目不一樣

Q23:
Which of the following can be inferred from the passage about the effect of the solar-day cycle on the tide-associated periodic behavior displayed by commuter diatoms?

A. The solar-day cycle makes this behavior less advantageous to the commuter diatoms at certain times of the year.
B. The solar-day cycle makes this behavior somewhat more erratic.
C. The solar-day cycle makes this behavior less important to the survival of the commuter diatoms.
D. Because of the solar-day cycle, this behavior is forced to proceed at a more rapid pace at certain times during the 24-hour day.
E. Because of the solar-day cycle, this behavior is not expressed at certain times during the 24-hour day.


答案E 請問是從哪裡看出來的 ??

答案E 請問是從哪裡看出來的 ??

Commuter diatoms, for example,
(65) emerge only during those low tides
that occur during the day.

代表不只潮汐有影響,還有日夜也有影響
只有白天會發生這種現象
因此可以推出e
因為solar-day cycle,使得這種現象只發生在白天,也就是不會24小時都有

請指教嚕

請問一下:
27.
According to the passage, the periodic behavior displayed by commuter diatoms under constant laboratory conditions is characterized by which of the following?

這句問題該怎麼理解??
