Unit10SectionAGrammarFocus～4c单元语法清作业课件人教版九年级英语全册

第三课时GrammarFocus～4c——单元语法清►besupposedtodosth.中的to是动词不定式符号，其后要跟动词原形；be随主语的人称、数和时态的变化而变化。(1)besupposedtodosth.意为“应该做某事”，它可以表示劝告、建议、义务、责任等，相当于情态动词should。Everyoneissupposedtowearaseatbeltinacar.每个人在坐车时都应该系安全带。(2)其否定形式为：benotsupposedtodosth.，常用于口语中，意为“不被许可/不应该做某事”。Youarenotsupposedtosmokeonthebus.你不应该在公交车上抽烟。(3)其一般疑问句形式为：Be＋主语＋supposedtodo＋其他？WasLucysupposedtolockthedoorwhenshelefttheclassroom?当露西离开教室时，她应该锁门吗？(4)其特殊疑问句形式为：特殊疑问词＋be＋主语＋supposedtodo＋其他？Whatarewesupposedtodotosavewaterinourdailylife?在日常生活中，我们应该做什么来节约用水？(5)was/weresupposedtodosth.相当于shouldhavedonesth.表示过去本应该做某事而并没有做。Thetrainwassupposedtoarrivehalfanhourago.火车本该在半小时之前到达。【注意】表示根据规定或传统习惯，人们应该做某事的时候，besupposedtodo和beexpectedtodo两者可以互换。但是beexpectedtodo比besupposedtodo的主观性更强。Sheisexpectedtobeagooddoctor.她有望成为一名好医生。►“Itis＋adj.＋todosth.”为固定句型，其中it是形式主语，真正的主语是动词不定式(短语)。因为动词不定式(短语)作主语相对较长，为了避免头重脚轻，所以用it作形式主语。【拓展】①“Itis＋adj.＋forsb.todosth.”意为“对某人来说做某事是……的”。此句型中的形容词常用于表示事物的特征、特点，如easy，hard，difficult，interesting，important，impossible等，用来说明后面的动词不定式。It'shardformetoansweryourquestion.我很难回答你的问题。②“Itis＋adj.＋ofsb.todosth.”意为“做某事某人是……的”。此句型中的形容词常用于表示人物的性格、品德，如good，kind，nice，clever，polite等，用来说明of后的sb.。It'sverykindofyoutohelpmewithmyEnglish.你帮助我学习英语真是太好了。to
