Although she is only 17 years old, she _________ drugs for two years.
A．AddictsB．has addicted to
C．has addictedD．has been addicted to
D

試題分析：句子有for+一段時(shí)間，很明顯要用完成時(shí)，根據(jù)句型sb be addicted to sth.某人沉迷于做某事。故選D 。句意：盡管她只有17歲，但她沉迷于毒品已經(jīng)兩年了。
點(diǎn)評(píng)：本題不難，掌握好固定詞但be addicted to.沉溺于，對(duì)…上癮，再注意要用現(xiàn)在完成時(shí)。
