参考答案

正确答案：C
解析：本题四个选项在拼写上较接近，但词义不同。dwarf常用意思为to cause to appear small by comparison，即“使相形见绌”，如：The new tall building dwarfs all the little shops．(新建的高楼使所有那些小商店相形见绌。)diminish的意思是cause to become or seem smaller，即“减少，缩小”，如：His illness diminished his strength．(他的疾病使他身体变弱了。)drown的意思是to cover up a sound by making a loud noise，即“(噪音)掩盖”，如：The noise of the train drowned his voice．(火车的噪音淹没了他的声音。)devastate的意思是to destroy completely，即“毁灭，破坏”，如：Their houses were devastated in the flood．(他们的房子在洪水中被毁了。)相比之下，drowned应该是正确答案。
