Question

请详细分析这句英语的语法结构

The big question for utilities is how much of coal’s declining share to replace with natural gas, and how much with renewables.

Answer 1

你提出了一很好的问题，这是 N。E。C。（4）lesson 2 中的句子，我理解这句是这样的：原句省略了一些字，as many people think （they are insects）。原句可写成： Spiders are not insects nor even nearly related to them，as many people think （ they are insects）。这句又相当于： Spiders are not insects nor even near related to them， though many people think（they are insects）。是带有表示相反（constrast）意思的状语从句的句子。为了更突出 “Spiders are not insects”与很多人的想法不一致，把 “as many people think” 移到前面，以插入语的形式出现——实际上是状语从句。它的意义为：尽管很多人以为蜘蛛是昆虫，但蜘蛛并不是昆虫……… 或与很多人的想法相反，蜘蛛不是昆虫……（意译）
