試題分析：考查虛擬語(yǔ)氣：句意：--對(duì)不起，你現(xiàn)在應(yīng)該交設(shè)計(jì)了。--對(duì)不起，我的電腦壞了，否則昨晚就已經(jīng)完成了。這里的or相當(dāng)于if my computer hadn’t broken down，主句應(yīng)該是和過(guò)去相反的虛擬語(yǔ)氣，選D。
點(diǎn)評(píng)：這題是隱含的if的虛擬語(yǔ)氣，or，otherwise相當(dāng)于非真實(shí)條件句，簡(jiǎn)要概括如下：1、表示與現(xiàn)在事實(shí)相反的情況，從句：If主語(yǔ)+過(guò)去時(shí)(Be動(dòng)詞用were)；主句：主語(yǔ)+should/would/could/might+do：　2、表示與過(guò)去事實(shí)相反的情況，從句：If主語(yǔ)+had+done；主句：主語(yǔ)+should/ would /could / might+have done　3、表示對(duì)將來(lái)情況的主觀(guān)推測(cè)，從句：①if+主語(yǔ)+were to do②if+主語(yǔ)+should+do ③if+主語(yǔ)+did（動(dòng)詞過(guò)去式）/were ；主句：主語(yǔ)+should/would/could/might+do。
