如何区分beside和besides

1、介词beside作“在...旁边”讲，可引申为“比起来”，“和...无关”等，如their discussion is beside the question他们的讨论离题了

3、副词besides作”此外“，”况且“讲，如the second颍骈城茇-hand car he bought was almost new. besides, it was in excelle荏鱿胫协nt condition他买的那辆二手车几乎是新的，而且运行状况极佳

5、若besides 与否定句连用，则表示除...外不再有...之意，可与except互换，如there is nothing on the table besides a floppy disk,桌上只有一个软盘
