选择题
I really don’t know how to express my thanks to Mr. Li, my high school English teacher, without whose help I__________ to college that year.
A．weren’t to go
B．hadn’t been able to go
C．couldn’t go
D．couldn’t have gone
答案
答案：D
考查虚拟语气。此题考查与过去事实相反的虚拟语气，主句应用：would/could/might + have done结构，句意：我真的不知道如何对李老师，我的高中英语老师表达感谢，没有他的帮助那一年我就上不了大学。所以选D。
