2016屆高考英語第一輪虛擬語氣語法專題教案
【結論1】名詞性從句中，表示“建議，命令，要求”等意義時，名詞性從句用(should)＋ 動詞原形。
一個堅持：insist
兩個命令：order, command (名詞是order, recommendation)
三個建議：advise, suggest，propose(名詞是advice, suggestion, proposal)
四個要求：demand, require, request, desire(名詞是demand, requirement, request, desire)
注意：1. suggest 意為“表明，暗示”時，不用虛擬語氣；
如：his face suggested that he was very sad.
2. insist意為“堅持認為，堅持說”時，不用虛擬語氣；
如：the man insisted my little brother was a thief.
【例句觀察】
我們應該掌握電腦知識，這是很重要的。
it is important that we (should) have a good knowledge of computer science.
你居然沒參加會議，真是可惜。
it is a pity that you (should) be absent from the meeting.
他竟然是名醫生，我們很驚訝。
we are surprised that he (should) be a doctor.
【結論2】虛擬語氣用在“it's＋形容詞 / 名詞＋that…”這類句型中，表示說話人“強烈”的感情色彩，此時，從句用should ＋動詞原形 / should ＋ have done (表示動作在過去已經發生)，should 可譯為“應該；居然，竟然”。should 可以省略。
①it is important / necessary / strange / surprising / funny / natural ＋ that－從句
②it is a pity / a shame / an honour / no wonder that－從句
③主語 ＋ be ＋ sorry / disappointed / surprised ＋ that－從句
【例句觀察】
以防錯過第一班車，我們一大早就起床了。
①we got up early for fear that we should miss the first bus.
②we got up early lest that we should miss the first bus.
【結論3】在in case, for fear (that), lest等引導的狀語從句中，謂語動詞用“should＋動詞原形”。
