A would not do
B hadn't done
C would not have done
D didn't do
答
答案是B. hadn't done
答
D. didn't do
前一句是虚拟，可翻译为：你本来可以通过驾驶考试的。言外之意就是没有通过。But...讲的是为什么没通过，可翻译为：但是你却练的不够。练的不够是已经发生了的，所以，用过去时didn't do。
答
选D
前面的could have done是本能够做某事却没能做 的意思.是对过去事情的评论.
but后面是对过去事情的客观阐述,直接用一般过去时.
答
d
第一句话是虚拟语气，could have done本可以做。后面是陈述语气，是客观事实。
你本可以通过驾照考试（假设），但你没有大量练习（现实）。
