8(這道題目是一個(gè)混合虛擬語(yǔ)氣的句子。條件句省19/37精品文檔略了if,把助詞had提前到主語(yǔ)前面,表示對(duì)過(guò)去情況的假設(shè),而主句中now表明了對(duì)現(xiàn)在情況的假設(shè),所以應(yīng)選would+動(dòng)詞原形這種表達(dá)形式。四個(gè)選項(xiàng)中只有是正確表達(dá)形式,故為正確答案。9(untilrecently,因此是正確答案,而主句是隱含的對(duì)現(xiàn)在情況的假設(shè),該句是一個(gè)混合虛擬條件句。10(假設(shè)的情況有時(shí)不是用一個(gè)條件句表示,而是隱含在一個(gè)由介詞如butfor、butthat、without,由連詞主格等表示的而沒(méi)有去即若不是因?yàn)橛⒄Z(yǔ)考試,我本可以去but、副詞otherwise、比較級(jí)、形本句主句表示對(duì)過(guò)去情況的假設(shè),但事實(shí)上由于英語(yǔ)考試聽(tīng)音樂(lè)會(huì),所以應(yīng)選Butfor為容詞、獨(dú)立上下文中。成,正確答案。11(題目中的第一句話表示的是現(xiàn)在真實(shí)的情況,而第二句話中所要表達(dá)的是應(yīng)該做但事實(shí)上沒(méi)有做的事,這種情況導(dǎo)致第一句話中真實(shí)情況的發(fā)生,故Ifonly條件句假設(shè)的是過(guò)去一種情況,因此應(yīng)該用had+過(guò)去分詞,所以正確答案是。12(D(注意主句now表示現(xiàn)在的時(shí)間狀語(yǔ),所以主句是對(duì)現(xiàn)在虛擬,從句是對(duì)過(guò)去虛擬。13(A(從句對(duì)過(guò)去的虛擬。14(B(從句表示虛擬,而主句是事實(shí)。15(it是形式賓語(yǔ),urgent是賓語(yǔ)補(bǔ)足語(yǔ),that引20/37精品文檔
