動詞的語態(tài)教學(xué)目標(biāo):被動語態(tài)的定義:2.被動語態(tài)的結(jié)構(gòu):3.被動語態(tài)的用法:一.重點:二.難點:1.靈活運用被動語態(tài)2.動詞的過去分詞
英語動詞有兩種語態(tài):
主動語態(tài)
(theActiveVoice)
被動語態(tài)(thePassiveVoice)A.主動語態(tài)表示主語是動作的執(zhí)行者。B.被動語態(tài)表示主語是動作的承受者。Weplantedthetree.Thetreewasplantedbyus.語態(tài)的概述:WespeakEnglish.主語謂語賓語Englishisspokenbyus.主語謂語賓語主動語態(tài)被動語態(tài)(1)不知道或沒有必要說明動作的執(zhí)行者是誰,不用by+動作執(zhí)行者短語。如:
Thedictionaryiswellkept.這本詞典被保存完好(不需要說明是誰保存的)。(2)強(qiáng)調(diào)動作的承受者,這時應(yīng)用by短語。
The
cup
was
broken
by
David.
這個杯子被大衛(wèi)打碎了。
(3)做客觀說明時,常采用一種被動語態(tài)句型:It’s
/
was
said
/
believed
/
reported
/
+
that
…據(jù)說/據(jù)報道……如:It’s
reported
that
about
three
hundred
people
were
killed
in
this
earthquake.被動語態(tài)的用法:
被動語態(tài)的構(gòu)成:
be+動詞的過去分詞如:Thedeskismadeofwood.Thedesksaremadeofwood.Heisaskedaquestionbytheteacher.Iwasgivenanicepresentbymyfriendyesterday.被動語態(tài)的結(jié)構(gòu):在改寫中應(yīng)注意:1.把原來的賓語提到前面作被動語態(tài)的主語;2.把動詞變成“be+過去分詞”;3.主動語態(tài)中的主語變?yōu)榻樵~by的賓語。主動語態(tài)變被動語態(tài)的方法:
例1將下列句子改為被動語態(tài)。
We
cleanourclassroomeveryday.
Ourclassroomiscleaned(byus)everyday.
