areyousupposed

todonow?现在你应该做什么？GrammarFocus一、besupposedtodosth.用法示例当besupposedto的主语是人时，意为“应该……”表示劝告、义务、责任等。当besupposedto的主语是物时，表示“本应；本该”。表示“某事应该发生却没有发生”。“besupposedto+have+及物动词过去分词”表示“本该做而没做”，是虚拟语气的一种表达方式，含有责备、失望之意。Youare(not)supposedtobowwhenyoumeetsomeoneforthefirsttime.你第一次见到某人时（不）应该鞠躬。Thetrainwassupposedtoarrivehalfanhourago.火车本应在半小时之前到达。Heissupposedtohavearrivedanhourago.他本该一小时前就到。作为青少年，我们应该学会如何照顾自己。Asteenagers,

we_____________________learnhowtolookafterourselves.(suppose)可用固定搭配法解答本题。besupposedtodosth.意为“应该做某事”，根据主语we可知be动词应选用are故填aresupposedto。

典例点拨aresupposedtoGrammarFocus一、besupposedtodosth.1.Itisveryimportanttorememberthis.2.Itishardworkclimbingmountains.3.Itisunknownwhenhewillcome.不定式为真正主语形式主语动名词为真正主语从句为真正主语形式主语形式主语

当不定式、动名词、从句等复杂成分作句子主语时，为保持句子平衡，通常把真正的主语放在句末，而在句首使用形式主语it。二、“Itbe+形容词+todosth.”句型GrammarFocusGrammarFocus二、“Itbe+形容词+todosth.”句型“Itbe+形容词+todosth.”意为“做某事是……的”，其中，it是形式主语，真正的主语是后面的动词不定式。常用于此句型的形容词有：important、necessary、easy、difficult等。e.g.It’seasytolearnEnglishifyouworkhard.如果你努力，学习英语很容易。GrammarFocus二、“Itbe+形容词+todosth.”句型①“Itbe+形容词+forsb.+todosth.”意为“对于某人来说做某事是……的”。此句型中的形容词是描述事物特征的，如：possible、difficult、necessary等。e.g.Itispossibleforyoutopasstheexam.对于你来说通过考试是可能的。②“Itbe+形容词+ofsb.+todosth.”意为“某人做某事是……的”。此句型中的形容词是描述人的性格、品质的，这类形容词有：polite、nice、kind、good、friendly等。e.g.It’skindofyoutohelpme.你帮我真是太好了。拓展Itisnecessary____ustohelpourfriendsoutwhentheymeetdifficulties.A．toB．ofC．withD．for可用固定搭配法解答本题。在句型“Itbe+形容词(for/ofsb.)+todosth.”中，of前的形容词通常是描述人的品质、性格的，for前的形容词通常是描述事物特征的。句中的形容词necessary并非指人的品质，而是描述事物的特征，所以此处用for。
