這是一段由BBC擷取的文字,(網站: http://www.bbc.co.uk/history/ancient/greeks/greek_olympics_print.html)

其中的一段:
For the first 13 Olympics there was only one event, the stadion race , which was a running race up one length of the
stadium. How long this race was is a matter for conjecture, as the ancient stadium, 192 meters long, visible at Olympia now,
did not exist then.

從How long....開始到 did not exist then 這句中有3個動詞: was, is, and exist 那至少要有2個連接辭, 但我怎找都找不到,是不是有人可以幫我分析一下, 感恩
