Question

he planed _ this expriement yesterday,but he didn't find time to do so. A.to have made b.to make

具体说明原因 谢谢

Answer 1

答案是A。
plan to have done 本计划做而没有做的事。
这个句型相当于用过去完成时表示想做而没有做的事。如：
I had wanted to help him, but I was too busy.
I had planned to go to the cinema with my husband, but I had to go to the hospital to see a friend of mine.

Answer 2

b.to make题写错了，应该是planned

Answer 3

B 表示plan 将来的动作，故用不定式的一般式
不定式的一般式常表将来动作，其完成式常表过去动作

Answer 4

看 叻 二楼的回答，我觉得有道理。

Answer 5

选 B。就是最普通的一般过去时。

Answer 6

planned to have made had planned to make 用过去完成时，或过去式＋to have done表示本成而未
