It is five years before I began to study English.有这种用法吗?答案是这样的
通常情况下是it is .since或者是it has been .since

有这样的用法.before常用作表时间关系的连词.但是,在这里,before是一个时间副词.另举例：Long long before,there was a war between the beasts and birds.很久很久以前,鸟和兽之间爆发过一场大战.（本句出自1984年全日制英语教材初中第五册第一课,为课文的首句）since则有介词和连词两种功能.
It is five years before I began to study English.正是五年前,我开始了学英语.这个句子是一个简略的强调结构句.如果把省略掉的先行词补出来,那就是It is five years before（that）I began to study English
再问： before是做时间副词？那它修饰什么呢？是before后面的从句吗？
再答：作为时间副词的before当然是用来限定行为动作（began to study English）的，把行为发生的具体时间说明白。当副词用来说明行为状态时，那是修饰关系。当副词用来具体说明行为发生的条件或度量的时候，那应该称作限定关系。修饰和限定是形容词、副词拥有的两种不同的功能。另外补充两个与本句对before的用法情况相同的句子。 ① I called him up last night， but his mother told me he had left for Wuhan two days before. ② She said that she had married him five years before.
