youvisittheScienceMuseum.1.if从句的构成：条件状语从句表示主句动作发生的条件，在初中阶段常由if(如果)引导。e.g.Pleasecallmeifheisathome.如果他在家,请给我打电话。2.if从句的位置:在“if从句+祈使句”结构中，if从句可以放在主句之前，也可放在主句之后。如果if从句放在主句前，从句与主句之间要用逗号隔开。e.g.Ifyouseehim,givehimthisnote.你要是见到他，就把这个便条给他。Youcanstayhereandreadthenovelifyoulike.你如果愿意就留在这里再看本小说吧。3.时态：在以if引导的条件状语从句中，

如果主句为祈使句，

从句通常用一般现在时。e.g.Putupyourhandifyouhaveanyquestionstoask.如果你有问题要问,请举手。在if引导的条件状语从句中，符合以下原则：原则1：主将从现主句是一般将来时，从句用一般现在时。e.g.Ifmybrothercomesback,hewilltakemetothepark.如果我哥哥回来了，他会带我去公园。原则2：主情从现

主句含有情态动词can/may/might/must/should等，从句用一般现在时。e.g.Ifyouwanttobehealthy,youshouldkeepagooddiet.如果你想要健康，你应该保持良好的饮食习惯。原则3：主祈从现主句是祈使句，从句用一般现在时。e.g.Don’tplaywiththeknifeifyoudon’twanttogethurt.如果你不想受伤，就不要玩刀子。7.Completethepassagewiththeexpressionsinthebox.Well,hereweareattheScienceMuseum.Todaywewillbelookingatancientandmoderntechnology.Youcanlearnabouthistory(1)_____________technology.That'sbecausechangesintechnologyhavechangedtheworld.aswell
