选C是过去分词做状语的用法,表示条件,即“如果被加热,液体能变成气体。”而B项是不定式结构,虽能做状语,但其本身常含有将来的意味,而句中所述情况为自然真理,并不依时间为转移,所以要选C,而不选B。
)___,liquids can be changed into gases.A.Heating B.To be heated C.Heated D.Heat本题要选一分词作为状语.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,…、为什么不...
Conduction in a Rotary Dryer or Rotary Kiln is at work by transferring heat from the shell of the rotary drum, to the bed of material, via direct contact. Convection With convection, which is the primary mode of heat transfer for gases and liquids, heat transfers from a heat source, ...
