till與until也有細微區別。till常用在非正式文體或口語中，而until則常用于正式文體及比較正式的場合。另外，在句首多用until.to可用在表示鐘點的詞前。我們說It’ssixt436.by,beforeby表示時間時，意思是“到……以前”、“不遲于”、“到……時（為止）”。例如：bysuppertime,bytheendoflasttermbefore表示時間，意為“在……以前”。例如：beforeliberation,thedaybeforeyesterday6.by,before44c）by與before的區別在于，by短語表示時間，強調“終止點”，而before短語表示時間，強調“起始點”。如：Yoursonwillbeallrightbysuppertime.句中的bysuppertime表示從說話時到晚飯前這段時間。而before構成短語則表示從某一時間或事件之前，如：Thepoorchildrencouldn’tgotoschoolbeforeliberation.c）by與before的區別在于，by短語表示時間，強調“終45表示地點的介詞above
