People in general have always assumed that the temperature of a leaf should be in sync with the temperature of the
surrounding air. However, it’s amazing that burning temperatures seldom turn the leaves on the tree into flames.
According to a study published in a famous science journal, Nature, this can be accounted for by the fact that as a result
of evolution, leaves tend to maintain at a comfortable, climate-conditioned 21 degrees Celsius. For instance, plants from
the subtropics, say Kaohsiung, have evolved mechanisms to adjust the temperature of their leaves by angling themselves
away from the sun. On the other hand, plants in mountain areas (e.g., Mountain Jade), where the weather is often chilly,
have developed ways to “heat” their leaves by putting out more leaves per branch to huddle for warmth. After all, what
other option does a plant have in an unpleasant environment? It cannot just migrate to a cooler place. 【題組】48 Which of the following words can replace the underlined word “angling” in the passage?
(A) Turning (B) Fading (C) Pulling (D) Sailing
