In（）, William Blake explores the relationship of the contraries. Attraction and repulsion, reason and energy, love and hate, are necessary to human existence.
A、Songs of Experience
B、Songs of Innocence
C、Marriage of Heaven and Hell
D、Poetical Sketches
【正确答案】：C
【题目解析】：在Marriage of Heaven and Hell《天堂与地狱的结合》(1790)中，威廉·布莱克的写作趋向了成熟，他探索了对立面之间的关系。吸引和排斥，原因和能量，爱与恨对人类的生存而言都是必要的。“Without contraries, there is no progression.”没有对立，那也就没有进步可言。
