原文： Just because chance had been ruled out as an explanation did not prove telepathy must exist; there were many other ways of getting positive results.
这里as使用方法是什么？我理解：作介词，讲解为“作为”；
must是表示“一定”的语气吗？；
这句话中主语是什么？an explanation吗？那Just because chance had been ruled out as 是作什么成分呢？
谢谢！
Just because chance had been ruled out as an explanation did not prove telepathy must exist; there were many other ways of getting positive results.
1 as为介词，意为“作为”，在because从句中作方法状语。
2 must在此表示推断意义，意为“一定、一定”
3 原文中just because从句作了主语。这是不规范的英语，是口语中说话人考虑不周而犯的口误。应该改为:
The fact that chance had been ruled out as an explanation did not prove telepathy must exist; there were many other ways of getting positive results.
