60、done”形式，故應在told前加had。 9．(2018·銀川模擬)She is always talking as though she knows everything under the sun． ________________________________________________________________________ 答案：knows→knew　句意暗含她不可能知道世界上所有的事情，因此此處要用虛擬語氣，且是對現在情況的虛擬。所以句子用一般過去時。 10．(2019·安徽皖南八校聯考)If he should not come tomorrow, we

61、put off the meeting till next Wednesday． ________________________________________________________________________ 答案：we后加would/could/might/should　句意：如果他明天不來的話，我們將把會議推遲到下周三。對將來情況的虛擬，主句謂語用“would/should/could/might＋動詞原形”。 虛擬語氣 一、虛擬語氣在非真實條件句中的用法 1．基本用法 2．混合虛擬語氣(錯綜時間條件句) 有時非真實條件從句的動作和主句的動作不同

62、時發(fā)生，或主從句的動作有一個是事實，這種情況下謂語動詞要根據各自的具體情況來確定。 If it had_rained last night, it would_be wet now． 3．含蓄虛擬語氣 有時非真實條件不是通過if引導的條件句來表現的，而是通過一些詞或短語來表示，如：without, but for, otherwise, but等。 I couldn't_have_finished the work on time without your help． But_for your timely warning, we would_have_got_into great

63、trouble． 4．非真實條件句中省略if的用法 如果非真實條件句的謂語動詞中有had, were, should，可省略if，而將had, were, should提前形成部分倒裝。 Had he taken my advice, he would not have made such a mistake． Should it be sunny tomorrow, we would go hiking． Were there no air or water, there would be no living things on the earth． 二、虛擬語氣用于其他從句中

64、 1．用于表示要求、命令、建議、推薦等意義的動詞，如：order, require, demand, suggest, advise, propose, command, request, insist, recommend等后接賓語從句時，從句謂語動詞為“(should＋)動詞原形”。由上述動詞派生或轉化的名詞的同位語從句或表語從句中也要用虛擬語氣。 The teacher ordered that all of the students (should)_be here on time． We followed his advice that we (should)_give up

65、the plan． His suggestion is that we (should)_accept these gifts． 注意：①suggest作“建議”講時，后面的從句用虛擬語氣；作“暗示，表明”講時，后面的從句用陳述語氣。 I suggest that you (should)_come here early tomorrow． All the evidence suggested that we were right． ②insist表示“堅決要求”或“堅持主張”之意時，其后用虛擬語氣，即(should＋)動詞原形；但表示“堅持說，堅持認為”之意時，其后使用陳述語氣。

66、 She insists that we (should)_leave at 6：00 tomorrow morning, or we might miss the flight． Little Tony insisted that he had_seen a man flying in the sky last night． 2．在as if, as though, if only引導的從句及wish引導的賓語從句中，與現在情況相反，從句謂語用過去式(be動詞常用were)；與過去情況相反，從句謂語用“had＋過去分詞”；與將來情況相反，從句謂語用“would/could/might/should＋動詞原形”。 He works with such enthusiasm as if he were never tired． He talked about the film as if/as though he had really seen it． 3．在“It is desired/suggested/requested/recommended/ordered/stra
