2019屆高考英語非謂語動詞語法專題教案
【疑難剖析3】can not (help / choose)but do，can do nothing but do，have no choice / alternative to do表示“不得不”。
【疑難4】
why not take a holiday?
【疑難剖析4】“why not ＋動詞原形”表達向某人提出建議，翻譯為：“為什么不……？”“干嘛不……？”
【疑難5】
you had better have your eyes examined.
【疑難剖析5】“would rather / had better＋(not)＋動詞原形”意為“寧愿 / 最好(不)做某事”。
【疑難6】
we don't want there to be any comrades lagging behind.
i don't mind there being a chair here.
there being nobody else at hand, i had to do by myself. [ ]
【疑難剖析6】there be的非謂語形式：
作動詞expect，like，mean，intend，want，prefer，hate賓語時，通常用there to be結構，在mind, object to等后面用there being。作狀語多用there being結構。
【疑難7】
john didn't pass his driving test, but i expected him to.
— hasn't he finished writing the report？
— no, but he ought to have.
— aren't you the headmaster?
— no, and i don't want to be.
【疑難剖析7】為避免重復，在hope, expect, wish, want, like, love, decide, plan, need, mean, forget, refuse, tell, know, have to, be going to, used to, ought to等動詞后面再次出現相同的不定式作賓語時，常出現單獨使用的to，而把曾出現過的動詞省略掉。但是，如果在省略的不定式結構中含有be, have, have been時，要保留這些詞。
三、不定式、動名詞和分詞作表語
【完成例句】
(11)我的建議是馬上開始工作。
what i would suggest is to start work at once.
(12)他的愛好是集郵。
his hobby is collecting stamps.
【結論1】不定式作表語一般表示具體動作，特別是表示將來的動作。動名詞作表語，表示抽象的一般性的行為。
【完成例句】
(13)旅行很有趣但有些累。
travelling is interesting but tiring.
(14)學生被迫學得太多會混亂的。
the pupils will get confused if they are made to learn too much.
【結論2】表心理狀態的interesting, exciting, delighting, disappointing, encouraging, worrying, puzzling, satisfying, surprising, pleasing等形容詞化分詞作表語時，表示“令人……的”；interested, excited, delighted, disappointed, encouraged, pleased, puzzled, worried, surprised等表示“感到……”。
【完成例句】
(15)工人們被告知他們按小時計酬。
what the workers have been told is that they get paid by the hour.
【結論3】除be done外， get, become, look, seem, appear, remain等系動詞都可跟done。如remain seated / hidden，get paid / dressed / changed / stuck / hurt / injured / burnt等。
