Answer 1

C

試題分析：句意：如果那個(gè)島現(xiàn)在仍然是個(gè)旅游景點(diǎn)的話，上周的地震可能會(huì)造成更多的傷亡。本題屬于考察混合虛擬語(yǔ)氣，if從句是對(duì)現(xiàn)在的情況進(jìn)行虛擬，用一般過(guò)去時(shí)，主句是對(duì)過(guò)去的虛擬，用would have done.故選C.
點(diǎn)評(píng)：if的虛擬語(yǔ)氣非常重要，對(duì)于混合虛擬語(yǔ)氣要根據(jù)各個(gè)時(shí)態(tài)的不同來(lái)選擇。if的虛擬語(yǔ)氣基本用法簡(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。
