till与until同义, 但在主句前的从句或短语中, 通常用until。例如:
Until then, I knew nothing at all about it.
在那时以前, 我对这事一无所知。
用法
USAGE: In most contexts, till and until have the same meaning and are interchangeable. The main difference is that till is generally considered to be more informal than until. Until occurs much more frequently than till in writing. In addition, until tends to be the natural choice at the beginning of a sentence: until very recently, there was still a chance of rescuing the situation. Interestingly, while it is commonly assumed that till is an abbreviated form of until (the spellings 'till and 'til reflect this), till is in fact the earlier form. Until appears to have been formed by the addition of Old Norse und (‘as far as’) several hundred years after the date of the first records for till.
