选择题
Joe Jones, the eldest of the eight children, had to ________ out of high school at the age of 16 to help his father on the farm.
A．leave
B．drop
C．fall
D．go
答案
B
题目分析：句意：Joe Jones是八个孩子中最大的，他16岁时不得不从高中辍学去农场帮助父亲。the eldest of the eight children 作Joe Jones的同位语；A．leave离开；后直接跟名词，不用接out of； C. fall 落下； D. go去；B. drop out of…表示“退出，离开……”，是固定短语，故选B。
