Answer 1

D

試題分析：句意：對(duì)不起，我現(xiàn)在太忙了，如果我有時(shí)間，我肯定和你去郊游。本句中if引導(dǎo)的從句表示對(duì)現(xiàn)在的情況進(jìn)行假設(shè)，從句用did，主句用would +do,故選D
點(diǎn)評(píng)：if的虛擬語(yǔ)氣非常重要，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
