过去分词作表语

学科班级设计教师使用时间课题必修5 Unit1 Great scientists ( The Past Participle )学习目标：enable students to learn how to use the past participle as the predicative correctly.学习重点：get students to learn and consolidate how to use the past participle as the predicative correctly.学习难点：the usage of the past participle as the predicative.导疑：一. 过去分词的含义:过去分词有“被动”或“完成”的意思，及物动词的过去分词既表被动也表示完成，但有时只表被动；不及物动词的过去分词只表完成。如：abrokenheart一颗破碎的心（被动和完成）arisensun已升起的太阳（完成）fallenleaves（落叶）（完成）导学：过去分词作表语1）过去分词作表语时总是用在系动词之后，构成系表结构，表示主语所处的状态，如：1. Shelookeddisappointed._2. Hebecameinterestedintwotheoriesthatpossiblyexplainedhowcholerakilledpeople._3. Hebecameinspiredwhenhethoughtabouthelpingordinarypeopleexposedtocholera._常用的系表结构be/getmarriedtosb. be/getstuck受困，被卡住，陷入belostinthought beseated bedevotedto bedressedin besurprised/astonished/shocked.at2.系表结构与被动结构的区别：1）二者都是由“be+done”构成，但系表结构中的过去分词表示主语所处的状态，被动语态则表示主语是动作的承受者。如：1Thelakeisbadlypollutedbythepapermill.这个湖被一家造纸厂严重污染了。（被动语态）2Heisdressedinwhiteuniform.（系表结构）_2)过去分词作表语时，句子主语多是人，表示主语的感受；现在分词作表语，句子主语多是物，它表示给别人造成的感觉。如：Thematchisexciting；Theaudienceareexcited._导行：跟踪训练1.The_glasscupwas_byTom.A.broken;breaking B.broken;broken C.breaking;breaking D.breaking;broken2.Aftertheheavyrain，manycarsgot_inthemud.A.catch B.catching C.caught D.beingcaught3.Whatsurprisedmemostwasthattheleaderofthatcountrygot_.A.kill B.killing C.killed D.tobekilled4.
