We wish we could have learned__when we were at high school.
A.what you did
B.that you had done
C.that what you did
D.what did you do
【解释下子哦~谢谢！！】

选A
这里是复合句， 两个复合从句， 第一个是 we could have learned__when we were at high school整个从句做宾语，作为宾语从句， 另一个， __when we were at high school这个做learn的宾语从句， 从句中的语序必须是陈述句语序， 所以排除D，D是疑问句语序。 you did 后面需要一个宾语，所以要what，当主谓宾都存在的时候才能用that，所以排除了B和C
