TPO15 A Warm-Blooded Turtle - 英檢

Paragraph 3: Leatherbacks keep their body heat in three different ways.
The first, and simplest, is size. The bigger the animal is, the lower as
surfaceto-volum e ratio; for every ounce of body mass, there is proportionately
less surface through which heat can escape. An adult leatherback is twice the
size of the biggest cheloniid sea turtles and will therefore take longer to
cool off. Maintaining a high body temperature through sheer bulk is called
gigantotherrny. █ It works for elephants, for whales, and, perhaps, it worked
for many of the larger dinosaurs. █ It apparently works, in a smaller way,
for some other sea turtles. █ Large loggerhead and green turtles can maintain
their body temperature at a degree or two above that of the surrounding water,
and gigantothermy is probably the way they do. █ Muscular activity helps,
too, and an actively swimming green turtle may be T C (12.6° F) warmer than
the waters it swims through.

12. Look at the four squares [█] that indicate where the following sentence could be added to the passage.
However, these animals have additional means of staying warm.
Where would the sentence best fit?

答案是4 我選2

想請問這題的解題思路？

寫到這題時 我時間不多了 看到these animals就覺得是指那些大型動物

看到解答後 就想說是不是因為It指gigantotherrny 所以1 2 都不可在插入其他句子

不然會造成主詞混淆

3 4 我就不知道要怎麼解釋了......

麻煩哪位強者幫幫我壓～～～
