5. I can well remember that there was a time when a deep blue sky, the song of the birds, moonlight and flowers could never have kept me spellbound. (reading p2)

(1)well= quite, much thoroughly非常,彻底,完全

(2)句式一:I can well remember that…(宾语从句)

句式二:there was a time when…(when为关系副词,引导定语从句,修饰前面先行词a time)

★(3)could never have done 结构表示“对过去情况的否定推测”,其否定副词never也可根据情况用not, hardly等此替换。

用法拓展:“情态动词 + have done”小结

(1) must have done  对过去发生事情的肯定推测。“一定……“

(2) could have done 过去可能做却未做。“本来可以做……”

(3) might / may have done 过去可能做了某事(可能性小)。“可能已经……”

(4) would have done 过去愿意做某事却不能做。“本来想要做……”

(5) shouldn’t oughtn’t to +have done 本来不该做却做了。

(6) should / ought to have done 应该做某事却没做。

(7) can’t / couldn’t have done 对过去发生事情的否定推测。“一定没有……”

(8) needn’t have done 过去没有必要做却做了。

I met him at the Grand Theater yesterday afternoon, so he __________ your lecture.

A. couldn’t have attended   B. needn’t have attended

C. mustn’t have attended   D. shouldn’t have attended

(A. 根据意思,他那时不可能去听讲座。此句式对过去的否定推测,用 couldn’t have done)

-------I didn’t go to see our former teacher while in Wuhan.

-------But I think you _________.

A. should  B. should have   C. could have  D. must

(B, 根据上下句意表责备,因此用should have done 结构。注意此处 have 不能省,是对过去的虚拟)
