2020屆中考英語虛擬語氣專題復習教案
⒈ 在表示愿望的動詞wish后的賓語從句中，需用虛擬語氣。（wish后的that 常省略），根據主句時態，從句謂語時態相應退后一位，例如：how she wished his family could go with him.
⒉ 在具有愿望、請求、建議、命令等主觀意愿的動詞(desire, demand, advice, insist, require, suggest, propose, order, recommend, decide …) 后的賓語從句中需用虛擬語氣。謂語動詞用(should) +動詞原形。值得注意的是，如果賓語從句的動詞是否定的，否定詞not的位置應在動詞之前，而不是動詞之后。例如：the head nurse insisted that the patient not be move.另外，如suggest表達“暗示”，insist表示“堅持某種說法”時，后面的從句不用虛擬語氣，例如：her pale face suggests that she is ill.或he insisted that he did not kill the boy.
除此之外，上述動詞也要求用虛擬式
① 在it is+上述動詞的過去分詞，其后所跟的主語從句中，如it is suggested that pupils wear school uniforms.
② 在上述動詞相應的名詞形式作主語+連系動詞，其后的表語從句中，例如his suggestion was that classed be re-scheduled.
③ 在對上述動詞相應的名詞進行解釋的同位語從句中，如：the workers raised the demand that their pay be increased to cope with the inflation.
⒊ would （had）rather , would sooner也用來表達主觀愿望，它們之后的賓語從句中需用虛擬語氣。謂語動詞用過去式表示現在或將來，用過去完成式表示與過去事實相反，例如：i would rather he went right now.
ⅲ其他形式的虛擬語氣
⒈ it is +necessary等形容詞后，that主語從句中虛擬形式使用，這類形容詞包括necessary, important, essential, imperative, urgent, preferable, vital, advisable等，例如it is necessary that you listen to the teacher carefully.或者it is essential that you be able to pronounce every single word correctly.
⒉ 在it's (high/about) time 之后的定語從句中需用虛擬語氣。謂語動詞用過去式，例如it is high time that you went to school
⒊ 虛擬語氣在as if / as though 引導的方式狀語從句中的應用（謂語動詞形式與wish后的賓語從句基本相同）表示與現在事實相反或對現在情況有懷疑，謂語動詞用過去式。例如：he felt as if he alone were responsible for what had happened. 表示過去想象中的動作或情況，謂語動詞用過去完成式。
⒋ 在lest 引導的狀語從句中，謂語動詞多用虛擬語氣，(should )+ 動詞原形。例如： the mad man was put in the soft-padded cell lest he injure himself.（1998年1月四級第38題）
⒌ 在if only 引起的感嘆句中需用虛擬語氣。謂語動詞用過去式或過去完成式。例如： look at the terrible situation i am in! if only i had followed your advice.
