选择题
--- Did you go to her birthday party held the day before yesterday?
--- I ____, but something unexpected happened at my home.
A．intended
B．had intended to
C．had intended to go
D．intended to go
答案
答案：B
考察虚拟语气同时考察不定式的省略。Had intended to do sth本打算做某事；根据后半句的过去时可知是与过去事实相反的虚拟语气。结合句意可知B正确。同时不定式省略时，可以省略后面的do,只保留不定式符号to.故B正确。
