B. a 19-year-old, washes
C. an 18-year-old, washed
D. an 8-year-old, washing
答案：
A. a 17-year-old, to wash
B. a 19-year-old, washes
(答案→)C. an 18-year-old, washed
D. an 8-year-old, washing
解析：
试题分析: 句意:安娜已经是个18岁的姑娘了，但是她很懒惰。她又想让别人给她洗衣服。get+ something+动词过去分词，让某物被别人做，表被动；eighteen的首音标是元音，前加不定冠词an，故答案选C.
