Heating B. To be heated C. Heated D. Heat答案C. 本题要选分词作为状语。现在分词表主动,正在进行的;过去分词表被动的,已经完成的。对于液体来说是加热的受动者,是被动的,因而选C。它相当于一个状语从句 When it is heated,,连词+分词(短语) 有时为使分词短语与主句关系更清楚,可在分词前加连词。 连词有: when,while,if though,after, before, as. 但分词的主语和主句的主语必须为同一个。例如:While waiting there, he saw two pretty girls come out of the building. 等在那儿时,他看见两个靓妹走出大楼。(waiting 和saw 的主语相同),Exercises:,1. _ some officials, Napoleon inspected his army.,Followed B.
