2019屆高考英語非謂語動詞語法專題教案
have you noticed the student losing himself / lost in thought?
【疑難剖析2】devote，absorb，lose，seat，dress，hide等動詞作狀語和定語時可以用它們的－ed形式(devoted, absorbed，lost，seated，dressed，hidden)或－ing＋oneself形式(devoting / absorbing / losing / seating / dressing / hiding oneself)。
【疑難3】
generally speaking，the more expensive the camera, the better its quality .
【疑難剖析3】有些to do 短語，doing短語和done 短語已經當作插入語使用，此時，句子的主語在邏輯上與它們不存在主動或被動關系：
① to tell you the truth(實話說)，needless to say(不用說)，to be honest / frank(老實說，坦白說)，to be more exact(更確切地說)，to make things worse (更糟的是)，not to mention…(更不用說)
② generally / frankly / roughly speaking (一般說來 / 坦白說 / 粗略地說)，considering…(鑒于 / 考慮到……)，judging by / from…(從……來看，依據……來判斷)，supposing that…(假定……)，providing that… (假定……)，according to…(依據……)，including…(包括……)，owing to…(由于……)，talking / speaking of…(談及……)
③given…(考慮到……), provided that…(如果……)
【疑難4】
it being sunday, we needn't go to school.
→ because it is sunday, we needn't go to school.
all the work done, you can have a rest.
→ if all the work is done, you can have a rest.
【疑難剖析4】獨立主格結構：n. / pron. ＋doing / done / to do / adv. / adj. / prep. 短語
前后主語不一致時，分詞作狀語需有自己的邏輯主語，且分詞與邏輯主語之間存在著邏輯上的主動或被動關系，此時，視為獨立主格結構。若把獨立主格結構還原為狀語從句，則主句的主語與從句的主語是不同的。
【疑難5】
連詞＋分詞(短語)
while waiting there, he saw two pretty girls come out of the building.
he will not attend the party unless invited.
【疑難剖析5】
有時為使分詞短語與主句關系更清楚，可在分詞前加連詞。連詞有when，while，if，unless，though，after, before, as等。但分詞的主語和主句的主語必須為同一個。
六、不定式和分詞作賓語補足語
【完成例句】
(26)我爸爸允許我周末上網。
my father permits me to surf the internet at the weekend.
【結論1】like, hate, encourage, wish, warn, tell, want, desire, expect, get, permit, order, allow, invite, force, ask, cause, advise, request, prefer, beg, persuade, teach, lead等動詞＋賓語＋to do sth. ，賓語與to do 為主動關系。
