倒装句的单选 怎么办啊

  选C。

碰到 倒装题，先看【考查点】。

考点熟于心，抉择 自然顺。

此题考查【虚拟语气中的倒装】，即在if引导的虚拟条件句中含有

were，should，had时，可将if省略，将were，should，had提前至句首，用成倒装。

  如：

Were I you,I wouldn't speak to my mother like that。

Should it rain tomorrow,we would not go out for a walk。

Had it not been for the your help,we couldn't have finished the work on time。

你所给的原句可还原为：

If energy were to flow spontaneously from a block of ice to a surrounding volume of water, this could occur in complete accord with energy conservation。

Were energy to flow spontaneously from a block of ice

to a surrounding volume of water, this could【要害 信息】

occur in complete accord with energy conservation。

选B.

Energy不可数，用单数，AC都错。

D时态/语态错。
