hcoatdidyouprefer?注：当宾语从句是陈述句时，用that连接从句。that在句中无词汇意义，在从句中不能充当成分，在口语当中往往省略。e.g.1.Ihear(that)_______________________.（一小时后他会回来）2.Hesaid(that)_________

_____________.（他非常想念我们）hewillbebackinanhourhemissedusverymuch由连词whether,if引导的宾语从句e.g.1.Askhim_____________________.（他是否能来）2.Idon’tknow_____________

_______.（是否要下雨）whether(if)hecancomewhetheritisgoingtorainornot当句末为ornot时，引导词只能用whether而不能用if.注：当宾语从句是一般疑问句时，用if/whether连接从句，意思是是否，注意

要将一般疑问句改为陈述语序。If与whether的区别1.Idon’tknow_____hewillcomeornot.2.Idon’tcareof______heishandsome.3.Hewondered____

是谓语的承受者时，用被动语态。汉语中常用“被，给，由，受”等词来表示被动，而英语中则用“be+动词的过去分词”来表示。Example:Wecleantheclassroomeveryday.我们每天都打扫教室。Th

eclassroomiscleaned(byus)everyday.教室每天都被(我们)打扫。1.被动语态的概念Presentation2.一般现在时的被动语态的结构肯定句：主语+am/is/are+过去分词+其他.Exa

+主语+过去分词+其他？Example:Whenwasthebridgebuilt?主动语态变被动语态第一步：主宾互换。第二步：谓语动词变为“be+过去分词”，并通过be的变化来表达出不同的时态。第三步：“be+过去分词”+by+原主语。（有时b

y+原主语可省）第四步：时间、地点状语等保持一致。主变被四步曲被动语态变化步骤宾变主,主变宾,前加by动变被,看清be,结构分别be+pp.bymanystudents.ManystudentsstudyEnglish.
