D

解析試題分析：句意：要是沒有雷雨的話，他們本能夠及時到達(dá)來幫助那個受傷的人的。他們對此表示很抱歉。if引導(dǎo)的從句是對過去發(fā)生的事情的假設(shè)，句子要用虛擬語氣。if從句用had done,主句用would/should/could/might +have done的形式。故選D.
考點(diǎn)：虛擬語氣
點(diǎn)評：if的虛擬語氣非常重要， 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。
