用了什么语法？
为什么翻译成它已经迅猛发展了。
为什么since放在这个位置呢？
它是什么形式的啊？

It has since developed very rapidly！
此句是非常普通的现在完成时.现在完成时表示过去发生或完成的某一动作对现在造成的影响或结果.这点应该不难理解.

比较奇怪一点的是since一词出现在句中的位置，因为平常我们用since一般是放在句首的；其实此句是作者将since提前到句句前部，since是时间状语，强调那个时间点之后，可以意译为"之后，以后".

也许将since还原为这样就比较好理解了：it has developed very rapidly since...(此句之前提到的事情)

同It has developed very rapidly since.这里since解释为以后，后来，用完成时表示已经发生的事情，所以这么解释。

have done 它就是一般现在完成时态啊表示现在完成了并对将来有影响.它还在发展着.
如果用was developed的话就是表示它已经发展完成了没有继续发展了.
very rapidly 是副词修饰动词develop 意思是迅速的发展.
