withoutdelay=quickly毫不拖延地9/40易混辨析：delay，putoff在表示“推遲某事”時能夠交換。e.g.Theflightwasdelayed/putoff

duetothebadweather.因為天氣不好，航班被推遲了。10/40但它們又有細微差異：（1）delay強調因某種困難或障礙厭惡，動作主體是人或困難本身，延遲時間不確定，也可能無限延遲。e.g.Mygrandmafellillallofasudden,whichdelayedourtrip.奶奶突然病倒了，延遲了我們旅行。

11/40（2）putoff強調“拖延時間”，指因客觀原因造成拖延或主觀上有意拖延。e.g.You’realwaysputtingoffthings.Youshouldgetridofthisbadhabit.你做事總是拖拉，你得克服這個壞習慣。
