选择题
Alcohol is also classified as a downer (镇静齐Ij), and though it is legal, it can damage the liver and do great harm if in large quantities.
A．consume
B．to consume
C．consuming
D．consumed
答案
答案：D
考查非谓语动词。句意“酒精也是镇静剂的一种，虽然是合法的，但是它也会对肝脏造成损害，如果大量吸收，会带来极大的伤害。”consume和alcohol是动宾关系，故用被动。相当于if it is consumed...。故选D。
