虛擬語氣教案

Thesubjunctivemood1語氣英語的動詞一般可帶有三種不同的語氣：陳述語氣，祈使語氣和虛擬語氣。不同的語氣用動詞的不同形式（有的還借助句法形式）來表示。2虛擬語氣虛擬語氣是一種特殊的動詞形式，一是用來表示說話人所說的話不是一個事實，而是一種假設(shè)、猜測、懷疑等(在條件從句中或讓步狀語從句中)；一是表示說話人的愿望、要求、命令、建議等(在賓語從句、表語從句、同位語從句)。虛擬語氣的概念3

一、虛擬語氣在條件句中虛擬條件句主句與現(xiàn)在事實相反的假設(shè)與過去相反的假設(shè)與將來相反的假設(shè)If+主語+動詞的過去式（動詞be用were)主語+should,would,might,could＋動詞原形If+主語+had+過去分詞主語＋should,would,might,could＋havedone1、If+主語+動詞過去式2、If+主語+wereto+動詞原形3、If+主語+should+動詞原形主語＋should,wouldmight,could＋動詞原形4eg:IfIhadtime,Iwouldattendthemeeting.
