Question

 (2010年南通二模)—Sorry indeed，I________to your birthday party if...

—Forget it.I know you were out on business.

A．must come                          B．would come

C．must have come                   D．would have come

Answer 1

解析：選D。考查虛擬語氣。此處表示對過去的虛擬，if后面省略了過去完成時(補充完整應該是if I had not been out on business)，所以主句中應該用should/would/could/might have done結(jié)構(gòu)，因此選D項。
