5.3.13带to的情态动词
带to的情态动词有四个：oughtto,haveto,usedto,beto,如加上havegottost,beableto，为六个。它们的疑问、否定形式应予以注意：
dotheyhavetopaytheirbillbeforetheendofthenth
shedidoplaytennisbeforesheeen.
yououghtnottohavetoldherallaboutit.
oughthetoseeaheartspecialistatonce.
oughtto本身作为情态动词使用。栗子网
www.lizi.tw其他的词作为实义动词使用，变疑问，否定时，须有do等助动词协助。
典型例题
toughtnottoyourse.
a.havetold b.tell c.betelling d.havingtold
答案a。由于后句为过去时，告诉秘密的动作又发生在其前因，此地应用过去完成时，但它在情态动词oughtto后，所以用havetold。
5.3.14比较need和dare
这两词既可做实义动词用，又可做情态动词用。作为情态动词，两者都只能用于疑问句，否定句和条件句。need作实义动词时后面的不定式必须带to，而dare作实义动词用时,后面的to时常可以被省略。
1实义动词：need需要,要求odosth
2情态动词：need，只用原形need后加do，否定形式为。例如：
needyougoyet你要走了吗
yes,ist.no,i.是的，我要走了不，不急着走。
5.4短语动词
动词加小品构成的起动词作用的短语叫短语动词。例如：
tuofftheradio. 把收音机关上。tuoff是短语动词
短语动词的构成基本有下列几种：
1动词副词，如：blackout；
2动词介词，如：lookinto；
3动词副词介词，如：lookforo。构成短语动词的副词和介词都统称为小品词。
