---No,___you hanve reached the age of 18.
A.up to
B.not until
C.till when
D.as far as
答案是B，请问为什么？
P194／26
not until
直到什么时候才
到十八岁的时候才可以
这里not until 是you can't until的简写
直到...才
省略句
全句：you can't have some sort of social life until you have reached the age of 18
until前是否定式,那到until后的时间就可开始怎么样了.
所以得选择B
这是省略句，全句是
You can't have any sort of social life until you have reached the age of 18.
not until
直到...才..
就是说到18岁才可以有社会生活
