John has been painting the door．（a）John has painted the door．（b）（a）句表示约翰刚刚把门油漆过，现在油漆还未干，所以你要小心。（b）句则无此含义，油漆可能已干了。2、现在完成进行时有时有延续性，现在完成时往往没有。如：They have been widening the road．（a）They have widened the road．（b）（a）句的意思是他们在加宽马路，但尚未完工。（b）句的意思则是已完工了。3、现在完成进行时往往表示动作在重复，现在完成时则常常不带重复性。如：Have you been meeting her lately？（a）Have you met her lately？（b）（a）句有“经常相会”之意，（b）句则没有。（b）句如与often，every day等时间状语连用，当然也表示动作在重复。1. — I’m sure Andrew will win the first prize in the final.— I think so.
