Itissaidthat.句型结构Itissaidthat.相当于Peoplesaythat.,意为“人们说”,属于“It+be+过去分词+that从句”结构，其中it是形式主语，真正的主语是that引导的从句。Itissaidthattheyhavewonthegame.据说他们赢得了那场比赛。【归纳拓展】It+be+过去分词+that从句(1)Itisbelievedthat.人们认为(2)Itissupposedthat.据猜测(3)Itisreportedthat.据报道(4)It'sknownthat.众所周知3. remain的用法remain用作不及物动词时，意为“剩下；停留；逗留”等。(2)remain用作连系动词时，意为“保持；仍是“，后接形容词、名词、分词或介词短语作表语。Theroomremainscoolallsummer.这个房间整个夏天保持凉爽。Sheremainedsittingwhentheycamein.他们进来时，她仍然坐着。4.smell的用法smell用作名词，意为“气味”。smell还可用作连系动词，后面跟形容词作表语，意为“闻起来”。Itgivesoffnicesmell.它散发出芳香的气味。Theflowerssmellgood.这些花儿闻起来很香。5.一般过去时的被动语态(1)构成：主语+was/were+及物动词的过去分词。(2)各种句式：肯定句：主语+was/were+及物动词的过去分词+其他。否定句：主语+was/were+not+及物动词的过去分词+其他。一般疑问句：Was/Were+主语+及物动词的过去分词+其他？特殊疑问句：特殊疑问词+一般疑问句式?(3)使用被动语态应注意的几个问题不及物动词无被动语态。Whatwillhappenin100years?100年后将会发生什么事？有些动词用主动形式表示被动意义。Thispenwriteswell.这支钢笔好用。Thisnewbooksellswell.这本新书很畅销。感官动词或使役动词使用省略to的动词不定式,主动语态中不带to,但变为被动语念时，必须加上to。Mymothermakesmedohouseworkeveryday.=Iammadetodohouseworkbymymothereveryday.妈妈每天让我干家务。Isawthemplaybasketballyesterday.=Theywereseentoplaybasketballbymeyesterday.昨天我看见他们打篮球了。作业布置1 .ReviewGrammarFocus.2 Readthepassageof3aafterclass.教后反思记2
