1、句子(句子分类，句型转换）句子的分类:由句子结构来讲，可分为三类简单一、简单句：由一个主语(或并列主语)和一个谓语（或并列谓语）构成的句子。eg.Wecleanedthewindowsandtidiedtheroom.二、并列句：由并列连词and,but,so,or,for等把两个或两个以上的简单句连起来的句子。eg.1)IcomefromChinaandhecomesfromJapan.2)Hurryup,oryou'llmissthetrain.3)Helookedforiteverywhere,
2、buthecouldn'tfindit.4)Shedidn'tknowtheanswertothequestion,sosheaskedtheteacher.5)He'sinterestedinmusicwhileJohnisinterestedinsports.三、复合句A.宾语从句：宾语从句在复合句中作主句的宾语，引导宾语从句的关联词有that,if/whether,what,who,whose,which,why,when,where,how等。1、连接词1) 由连接词that引导陈述句
3、，在口语中that常省略。eg.Hesaidthathewouldliketoseetheheadmaster. 2)由连接词whether/if引导一般疑问句，whether和if常可互换，但下列场合一般用whether.①介词后的宾语从句：I'mthinkingofwhetherhe'llcome.②与ornot连用：Idon'tknowwhetherIshouldgoornot.3)由连接代词what,who(whom,whose)which或连接副词when,where,why,how引导特殊
4、疑问句。eg.Doyouknowwho/whomsheiswaitingfor?2、语序：不管宾语从句是陈述句、一般疑问句或特殊疑问句，都要用陈述句语序，也就是说主谓次序不能颠倒。连接词＋主谓结构(1).Billwantedtoknowwhodidthis.(2).Idon'tknowwhat'sthematterwithBob?(3).Idon'tknowwhat'swrongwiththem?3、时态：一般说来，主从句时态要统一。如果主句是一般现在时，从句可根据需要用其它任何时态；如果主句是一般过
5、去时，从句应该用相应的过去时态范畴（也就是用一般过去时，过去进行时，过去将来时，过去完成时）。eg.①Lilywantedtoknowwhetherhergrandmalikedthehandbag.②Iaskedtheteacherwherewewouldhavethemeeting.③CouldyoutellmehowIcangettothezoo?如果从句表明的是一个客观事实或真理，那么无论主句是什么时态，从句都只能用一般现在时。eg.Theteachertoldusthatlighttrave
6、lsmuchfasterthansound.注意：在think后的宾语从句，如果需要表示否定意义，一般不在宾语从句中否定，而是在主句中否定。eg.Idon’tthinkthatEnglishiseasy.IthinkthatEnglishisnoteasy.(误)练习题：（一）①Howdoeshegetonwithhisnewclassmates?Couldyoutellme?(改为含有宾语从句的复合句)Couldyoutellmehow_________onwithhisnewclassmates?
