Question

If the island               a tourist attraction, last week’s earthquake would have caused far more deaths.

A．is to remain

B．has remained

C．remained

D．would remain

Answer 1

C

試題分析：句意：如果那個島現(xiàn)在仍然是個旅游景點(diǎn)的話，上周的地震可能會造成更多的傷亡。本題屬于考察混合虛擬語氣，if從句是對現(xiàn)在的情況進(jìn)行虛擬，用一般過去時，主句是對過去的虛擬，用would have done.故選C.
點(diǎn)評：if的虛擬語氣非常重要，對于混合虛擬語氣要根據(jù)各個時態(tài)的不同來選擇。if的虛擬語氣基本用法簡要概括如下：1、表示與現(xiàn) 在事實(shí)相反的情況，從句：If主語+過去時(Be動詞用were)；主句：主語+should/would/could/might+do：　2、表示與過去事實(shí)相反的情況，從句：If主語+had+done；主句：主語+should/would/could/might+have done　3、表示對將來情況的主觀推測，從句：①if+主語+were to do②if+主語+should+do ③if+主語+did（動詞過去式）/were ；主句：主語+should/would/could/might+do。
