动词不定式具有名词、形容词和副词的特征，因此可以在句中作主语、宾语、宾语补足语、定语和状语等。★可以放在一些动词后面用作宾语，这些动词有want,plan,agree,ask等。你必须学着照顾自己。Youmustlearn

tolookafteryourself.我让他周日到达。ItellhimtoarriveonSunday.★可作宾语补足语，表示宾语所做的动作，这些动词有tell,ask,want,like等。PractisePractise★有一些动词后用作宾语补足语的不定式通常不带to。一类是感官动词，常见的有see,hear,watch,feel,notice等；另一类是使役动词，常见的let,make,have等。听说你病了我很难过。Iamsorry

tohearthatyouareill.★动词不定式作状语常用在“be+形容词+不定式”这种结构中。如：Whentostartisnotdecidedyet.还没决定什么时候开始。(作主语)Theproblemiswheretohavetheparty.问题是去哪办聚会。(作表语)Idon’tknowwheretogo.我不知道去哪。(作宾语)★动词不定式可以和what,which,where,when等连用，在句中可作主语、表语和宾语。如：根据汉语提示补全句子。1.你愿意帮忙打扫城市公园吗？
