Question

__________you were coming today, I’d have met you at the railway station.

A．Have I known

B．Had I known

C．I have known

D．I had known

Answer 1

B

解析試題分析：考虛擬條件句的省略倒裝句：句意：如果我知道你今天要來這兒，我就會到火車站去接你了。這是一個虛擬條件句，正常的表達(dá)是：if I had known you were coming today, I’d have met you at the railway station.在虛擬語氣里面，如果有if就用正常的語序，省略if是要把had，were，should提前，選B。
考點(diǎn)：考查條件句的虛擬語氣的省略倒裝句
點(diǎn)評：if的虛擬語氣非常重要，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，從句也可以省略if，把had，were，should提前。
