弱弱問GWD-TN-21 Q15

Reptiles, by drawing their body heat directly from the Sun rather than burning calories to generate it, can survive on ten percent of the nourishment that a mammal of similar size would normally require

 

1. rather than burning calories to generate it
2. rather than the generation of body heat by burning calories

3. and not from generating it by burning calories

4. instead of by burning calories for generating it

5. instead of body heat generated by burning calories

 

Buring calories to generate it 是與drawing 並列還是同the sun 並列？

同问，若选A，则drawing their body heat directly from the Sun 与burning calories to generate it平行，it是不是还可以就近指代sun，造成歧义？
另外burning前面不需要加个by构成平行吗？还是by可以省略。

E选项，可不可以理解为the Sun与body heat平行，即：from A instead of B

搞不清楚rather than, instead of 有木有哪个表达更好的说法。

求解释T T

quote：


"instead of" contains "of" -- a preposition -- and so it must be followed by a noun.
i bought a car instead of a truck --> this sentence is fine.
the sleeves were long instead of short --> this is not fine, because "long" and "short" are not nouns.


i bought a car rather than a truck --> this sentence is fine.
the sleeves were long rather than short --> this sentence is also fine.


there's also a slight difference in meaning between the two.


* "instead of" carries the implication that the following noun is some sort of standard, and/or was expected in the situation at hand.


so, i bought a car instead of a truck means that i was supposed to buy a truck, but nonetheless bought a car instead.


* "rather than" carries no such implication that one of the two items is standard/expected.


i bought a car rather than a truck just means that i had both options but chose the car.

原句是一个并列，by drawing their body heat directly from the Sun 和by burning calories to generate it，然后省略了后一个by。
